  • There is no need for precise measurements, you can round the measurement to the nearest 1/2" size. e.g. If your duct opening measures 9-3/4" x 9-3/4" a 10x10 cover will work. - Source: Internet
  • Multiple inventions within this time frame preceded the beginnings of the first comfort air conditioning system, which was designed in 1902 by Alfred Wolff (Cooper, 2003) for the New York Stock Exchange, while Willis Carrier equipped the Sacketts-Wilhems Printing Company with the process AC unit the same year. Coyne College was the first school to offer HVAC training in 1899.[13] - Source: Internet
  • Ventilation is the process of changing or replacing air in any space to control the temperature or remove any combination of moisture, odors, smoke, heat, dust, airborne bacteria, or carbon dioxide, and to replenish oxygen. Ventilation often refers to the intentional delivery of the outside air to the building indoor space. It is one of the most important factors for maintaining acceptable indoor air quality in buildings. Methods for ventilating a building may be divided into mechanical/forced and natural types.[18] - Source: Internet
  • Sometimes, you may experience no air coming out of vents in one room in your house. If this happens, make sure that the particular room’s air vent is fully open and not accidentally closed or left partially open. Another reason for the room to experiences no airflow may be that it’s too far from the unit and this implies that you have an underpowered AC. Try closing some air vents in bathrooms, closets, and hallways to see if you get better airflow to the affected room. - Source: Internet
    1. Check the plate on your furnace to see how many British thermal units (BTUs) it produces. This number needs to be divided by 10.000. - Source: Internet
  • Each volume of the ASHRAE Handbook is updated every four years. The Fundamentals Handbook includes heating and cooling calculations. The design professional must consult ASHRAE data for the standards of design and care as the typical building codes provide little to no information on HVAC design practices; codes such as the UMC and IMC do include much detail on installation requirements, however. Other useful reference materials include items from SMACNA, ACGIH, and technical trade journals. - Source: Internet
  • The control circuit in a household HVAC installation. The wires connecting to the blue terminal block on the upper-right of the board lead to the thermostat . The fan enclosure is directly behind the board, and the filters can be seen at the top. The safety interlock switch is at the bottom left. In the lower middle is the capacitor - Source: Internet
  • The drip pan we mentioned above can become rusted with time. If you’ve changed your filters and the coils aren’t frozen, check the pan to see if it needs to be replaced. If it does, click here for instructions on how to replace it. - Source: Internet
  • If you want to focus first on what is being delivered to the exhaust fan destination by your 60 cm supply duct, insert the 2-probes or the hand-held anemometer I cited into the ductwork at a convenient accessible location downstream from the blower fan itself. By definition, in the supply duct means you are measuring “downstream’ of the blower fan itself. Measuring in the supply plenum is more difficult (rectangular) and requires more probes. - Source: Internet
  • Generally, we practices a 0.1 in.wg of friction loss when sizing ducts. Low friction loss is good for energy savings but it’ll result in much larger duct sizes which increases the overall cost of the ducts. - Source: Internet
  • However, this is obviously a very complicated measurement—and becomes all the more complicated depending upon the size and shape of your ducts. For this reason, it is usually best to leave friction loss rate calculations up to a professional contractor. But you can find a general number using an online friction loss calculator. - Source: Internet
  • Knowing the friction loss rate helps contractors determine the static pressure of air throughout the ductwork. This has a big impact on air flow. Friction loss rate is impacted by the length of the duct and number of coils, filters, registers, grills, damper, and turns. Measuring friction loss rate is complex and should be done by an experienced contractor. - Source: Internet
  • Handheld anemometers are an excellent, portable tool for performing tests on HVAC system performance; however, large rotating vanes can prevent easy access to ducts. Dwyer introduces the Model VT-200 Vane Thermo-Anemometer to eliminate this problem. Additionally, simple keypad programming enables the user to view volumetric flow rates in CFM or CMM. - Source: Internet
  • HVAC systems work a lot more efficiently when the ductwork you use is the right size for your home. Install duct sizes that are too small, and your system will have to work harder to keep your home heated and cooled. If your duct sizing is too big, the velocity will be compromised, meaning you may not be able to feel it through the air vents. - Source: Internet
  • Because an air conditioner moves heat between the indoor coil and the outdoor coil, both must be kept clean. This means that, in addition to replacing the air filter at the evaporator coil, it is also necessary to regularly clean the condenser coil. Failure to keep the condenser clean will eventually result in harm to the compressor because the condenser coil is responsible for discharging both the indoor heat (as picked up by the evaporator) and the heat generated by the electric motor driving the compressor. - Source: Internet
  • In variable climates, the system may include a reversing valve that switches from heating in winter to cooling in summer. By reversing the flow of refrigerant, the heat pump refrigeration cycle is changed from cooling to heating or vice versa. This allows a facility to be heated and cooled by a single piece of equipment by the same means, and with the same hardware. - Source: Internet

  • Winter situation: In the winter, you run heating (usually a furnace). If you don’t have enough return air, in winter you will notice that rooms closer to the furnace are hotter. Rooms further away from the furnace are colder. - Source: Internet
  • Another accessory used to help regulate room temperature or increase energy efficiency is air vent covers. Cold and heat vent covers completely cover an air register to redirect forced air to other areas. They also help you seal off locations that don’t require temperature control, like the attic. - Source: Internet
  • Central, “all-air” air-conditioning systems (or package systems) with a combined outdoor condenser/evaporator unit are often installed in North American residences, offices, and public buildings, but are difficult to retrofit (install in a building that was not designed to receive it) because of the bulky air ducts required.[23] (Minisplit ductless systems are used in these situations.) Outside of North America, packaged systems are only used in limited applications involving large indoor space such as stadiums, theatres or exhibition halls. - Source: Internet
  • Rooms closest to the HVAC unit will have a bigger airflow. Rooms that are far from the HVAC unit will have a lower airflow. In essence, an HVAC unit generates high air pressure. Close to the unit, the pressure will still be high, and you will see air blowing from the return vent. Far from the unit, the pressure will fall and you will see not enough return air from those vents. - Source: Internet

  • Ducts are made of sheet metals and metal is a commodity. Hence, we can’t ask manufacturers to buy their metals from a cheaper supplier. So, the best way to save cost is to use duct sizes with the least amount of area which happens to be square-shaped ducts. - Source: Internet
  • Mechanical, or forced, ventilation is provided by an air handler (AHU) and used to control indoor air quality. Excess humidity, odors, and contaminants can often be controlled via dilution or replacement with outside air. However, in humid climates more energy is required to remove excess moisture from ventilation air. - Source: Internet
  • Ventilating or ventilation (the “V” in HVAC) is the process of exchanging or replacing air in any space to provide high indoor air quality which involves temperature control, oxygen replenishment, and removal of moisture, odors, smoke, heat, dust, airborne bacteria, carbon dioxide, and other gases. Ventilation removes unpleasant smells and excessive moisture, introduces outside air, keeps interior building air circulating, and prevents stagnation of the interior air. Methods for ventilating a building are divided into mechanical/forced and natural types.[2] - Source: Internet
  • When the AC filters are clogged with dirt, hair, dust, and other debris, the airflow through the vents in your home may be reduced, decreasing the efficiency of your air conditioning system. This can also happen if the AC filters are blocked by some furniture placed right in front of the system. To avoid this, be sure to change or clean your AC filters at least once a month and keep the space around your AC free of obstacles. - Source: Internet
  • For this process to work perfectly, the ducts need to be the right size. If your ducts are too small, the air that your HVAC pumps will increase in pressure which will back up into the system. Over time, this will reduce the efficiency of your AC and its lifespan due to unnecessary resistance to the blower fan. - Source: Internet
  • However, we advise against eyeballing it because even though an HVAC duct sizing rule of thumb is a great start, there are many factors at play here. Additionally, this rule of thumb can vary depending on the home and the HVAC system itself. We recommend contacting an HVAC professional to get the exact size of the ducts you need. - Source: Internet
  • So change your air filters regularly. How often you’ll have to do it depends on many factors: The size of your home, how many people live in it, whether you have any pets, and whether any of you have allergies. The best thing you can do is to check them every month. If they look dirty, change them. - Source: Internet
  • Heaters exist for various types of fuel, including solid fuels, liquids, and gases. Another type of heat source is electricity, normally heating ribbons composed of high resistance wire (see Nichrome). This principle is also used for baseboard heaters and portable heaters. Electrical heaters are often used as backup or supplemental heat for heat pump systems. - Source: Internet
  • Energy efficiency can be improved even more in central heating systems by introducing zoned heating. This allows a more granular application of heat, similar to non-central heating systems. Zones are controlled by multiple thermostats. In water heating systems the thermostats control zone valves, and in forced air systems they control zone dampers inside the vents which selectively block the flow of air. In this case, the control system is very critical to maintaining a proper temperature. - Source: Internet
  • The condensate drain line is outside of your home. Just as with air filters, over time, it will become clogged with dust, dirt, debris, mildew, algae, or maybe even a rodent or bug who decided to make the drain line its home. To unclog it, you’ll need either a shop vac or distilled vinegar. - Source: Internet
  • The HVAC industry is a worldwide enterprise, with roles including operation and maintenance, system design and construction, equipment manufacturing and sales, and in education and research. The HVAC industry was historically regulated by the manufacturers of HVAC equipment, but regulating and standards organizations such as HARDI (Heating, Air-conditioning and Refrigeration Distributors International), ASHRAE, SMACNA, ACCA (Air Conditioning Contractors of America), Uniform Mechanical Code, International Mechanical Code, and AMCA have been established to support the industry and encourage high standards and achievement. (UL as an omnibus agency is not specific to the HVAC industry.) - Source: Internet
  • Heating, ventilation, and air conditioning (HVAC)[1] is the use of various technologies to control the temperature, humidity, and purity of the air in an enclosed space. Its goal is to provide thermal comfort and acceptable indoor air quality. HVAC system design is a subdiscipline of mechanical engineering, based on the principles of thermodynamics, fluid mechanics, and heat transfer. “Refrigeration” is sometimes added to the field’s abbreviation as HVAC&R or HVACR, or “ventilation” is dropped, as in HACR (as in the designation of HACR-rated circuit breakers). - Source: Internet
  • Other issues are things like making sure the windows are tightly sealed, walls are actually insulated, etc. Often the ducts are leaky too, so if you can seal them you might get more air into and out of the end runs. If you can access them you might also consider insulating the supply ducts to these registers. I’ve been able to do this for some of my other runs–particularly one running through an uninsulated storage space. - Source: Internet
  • In more complex schemes, warm air is allowed to rise and flow out high building openings to the outside (stack effect), causing cool outside air to be drawn into low building openings. Natural ventilation schemes can use very little energy, but care must be taken to ensure comfort. In warm or humid climates, maintaining thermal comfort solely via natural ventilation might not be possible. Air conditioning systems are used, either as backups or supplements. Air-side economizers also use outside air to condition spaces, but do so using fans, ducts, dampers, and control systems to introduce and distribute cool outdoor air when appropriate. - Source: Internet
  • Although HVAC is executed in individual buildings or other enclosed spaces (like NORAD’s underground headquarters), the equipment involved is in some cases an extension of a larger district heating (DH) or district cooling (DC) network, or a combined DHC network. In such cases, the operating and maintenance aspects are simplified and metering becomes necessary to bill for the energy that is consumed, and in some cases energy that is returned to the larger system. For example, at a given time one building may be utilizing chilled water for air conditioning and the warm water it returns may be used in another building for heating, or for the overall heating-portion of the DHC network (likely with energy added to boost the temperature).[4][5][6] - Source: Internet
  • If your AC vent is dripping, reach up and feel for any air escaping from around the sides of the air vents first. This is a common issue and one that is very easy to fix. If air is escaping from anywhere other than the grates, caulking the leak is all you need to do. - Source: Internet
  • If you’ve purchased floor registers, you likely won’t have to deal with screws. Installation is usually as simple as removing the registers from their packaging and carefully inserting them into the air vent slot. The wider side of your floor register will be facing up so that the lip rests on the edges of the floor, while the more narrow side will face downwards into the hole. - Source: Internet
  • Next, we need to talk about the cubic feet per minute, or CFM. This measurement indicates the air velocity or flow needed to accurately heat or cool a room. Since the size of your ductwork can increase or lower this measurement, you’ll have to find the necessary CFM for each room before you can get the right duct size for each space. - Source: Internet

  • Free cooling systems can have very high efficiencies, and are sometimes combined with seasonal thermal energy storage so that the cold of winter can be used for summer air conditioning. Common storage mediums are deep aquifers or a natural underground rock mass accessed via a cluster of small-diameter, heat-exchanger-equipped boreholes. Some systems with small storages are hybrids, using free cooling early in the cooling season, and later employing a heat pump to chill the circulation coming from the storage. The heat pump is added-in because the storage acts as a heat sink when the system is in cooling (as opposed to charging) mode, causing the temperature to gradually increase during the cooling season. - Source: Internet
  • Air cleaning and filtration removes particles, contaminants, vapors and gases from the air. The filtered and cleaned air then is used in heating, ventilation, and air conditioning. Air cleaning and filtration should be taken in account when protecting our building environments.[34] - Source: Internet
  • Why Is the Air Blowing from My Central AC Weak? If you are experiencing weak airflow from vents in the house, check whether it is happening only in one vent or multiple vents. In case only one vent shows the problem, you may be having a problem with a disconnected or leaky duct, a crushed duct flex or a closed damper. On the other hand, if you experience weak airflow in multiple vents, the problem may be blower issues, air duct problems, small or blocked return vents, a dirty air filter, or a frozen evaporator coil. - Source: Internet
  • The use of furnaces, space heaters, and boilers as a method of indoor heating could result in incomplete combustion and the emission of carbon monoxide, nitrogen oxides, formaldehyde, volatile organic compounds, and other combustion byproducts. Incomplete combustion occurs when there is insufficient oxygen; the inputs are fuels containing various contaminants and the outputs are harmful byproducts, most dangerously carbon monoxide, which is a tasteless and odorless gas with serious adverse health effects.[16] - Source: Internet

  • While registers are placed on the output end of the HVAC system, grilles are attached to the input side where the air is pulled into the system. Return grilles are considered the most economical way to return air to your heating and cooling system. To work properly, our grilles: - Source: Internet
  • Kitchens and bathrooms typically have mechanical exhausts to control odors and sometimes humidity. Factors in the design of such systems include the flow rate (which is a function of the fan speed and exhaust vent size) and noise level. Direct drive fans are available for many applications and can reduce maintenance needs. - Source: Internet
  • Refrigerant is your AC’s coolant. Unlike a car, it doesn’t need to be replaced or topped off unless there’s an issue with the unit, such as a freon leak. However, they should only be fixed by HVAC experts, since exposure to it may cause refrigerant poisoning. - Source: Internet
  • How it works is quite simple – the plenum which stores the air is attached to multiple air ducts (there are usually two of these plenums in your system). First, the HVAC fills the supply plenum with air that gets expelled through the ductwork. This new air pushes the existing air into a different set of ducts that are connected to a return plenum. - Source: Internet
  • Available in wood, plastic and a variety of metals, our vent floor registers come in a range of styles and designs to match your décor. “Vent covers” is a general term that is used to describe the covers placed over air ducts where heated or cooled air emerges from your HVAC unit. The technical term for these covers is registers. Our top-rated ceiling and floor registers include some of the following designs: - Source: Internet

Building Services is part of a sector that has over 51,000 businesses and employs represents 2%-3% of the GDP. - Source: Internet
  • The heat pump gained popularity in the 1950s in Japan and the United States.[14] Heat pumps can extract heat from various sources, such as environmental air, exhaust air from a building, or from the ground. Heat pumps transfer heat from outside the structure into the air inside. Initially, heat pump HVAC systems were only used in moderate climates, but with improvements in low temperature operation and reduced loads due to more efficient homes, they are increasing in popularity in cooler climates, they can also operate in reverse by cooling an interior. - Source: Internet
  • The three major functions of heating, ventilation, and air conditioning are interrelated, especially with the need to provide thermal comfort and acceptable indoor air quality within reasonable installation, operation, and maintenance costs. HVAC systems can be used in both domestic and commercial environments. HVAC systems can provide ventilation, and maintain pressure relationships between spaces. The means of air delivery and removal from spaces is known as room air distribution.[3] - Source: Internet

  • Keep in mind that measuring near the exhausdt fan itself or ahead of the exhaust fan (less convenient in your design) is not going to tell us the effects of downstream bends, obstructions, air registers, or other variations in the system. In fact comparing a measurement near the air handler with those made at points of supply into rooms can be diagnostic. - if I correctly understand the problems you’re solving. - Source: Internet
  • With the split system, the evaporator coil is connected to a remote condenser unit using refrigerant piping between an indoor and outdoor unit instead of ducting air directly from the outdoor unit. Indoor units with directional vents mount onto walls, suspended from ceilings, or fit into the ceiling. Other indoor units mount inside the ceiling cavity so that short lengths of duct handle air from the indoor unit to vents or diffusers around the rooms. - Source: Internet
  • Before you start, make sure your system is off. You’ll need a screwdriver to remove the screws, and a step ladder if your vents are located higher up. Most decorative or heavier plated floor registers don’t have screws, but you may want a flathead to help lift it from the floor. - Source: Internet

  • All modern air conditioning systems, even small window package units, are equipped with internal air filters. These are generally of a lightweight gauze-like material, and must be replaced or washed as conditions warrant. For example, a building in a high dust environment, or a home with furry pets, will need to have the filters changed more often than buildings without these dirt loads. Failure to replace these filters as needed will contribute to a lower heat exchange rate, resulting in wasted energy, shortened equipment life, and higher energy bills; low air flow can result in iced-over evaporator coils, which can completely stop airflow. Additionally, very dirty or plugged filters can cause overheating during a heating cycle, which can result in damage to the system or even fire. - Source: Internet
  • If your air filters are dirty, the dust and debris block the air flow. Instead of dripping condensation drops into the drip pan, the water will freeze over the AC’s evaporator coils, forming a thin layer of ice. The longer you keep the dirty filters, the thicker the layer of ice becomes. This ice will start dripping as it melts, causing the water to drip from your vents. - Source: Internet
  • In modern buildings, the design, installation, and control systems of these functions are integrated into one or more HVAC systems. For very small buildings, contractors normally estimate the capacity and type of system needed and then design the system, selecting the appropriate refrigerant and various components needed. For larger buildings, building service designers, mechanical engineers, or building services engineers analyze, design, and specify the HVAC systems. Specialty mechanical contractors and suppliers then fabricate, install and commission the systems. Building permits and code-compliance inspections of the installations are normally required for all sizes of buildings. - Source: Internet
  • Cubic feet per minute is calculated by multiplying the size of the HVAC unit (in tons) by 400. Divide the answer by your home’s square footage to find out total CFM.

  • Demand controlled kitchen ventilation (DCKV) is a building controls approach to controlling the volume of kitchen exhaust and supply air in response to the actual cooking loads in a commercial kitchen. Traditional commercial kitchen ventilation systems operate at 100% fan speed independent of the volume of cooking activity and DCKV technology changes that to provide significant fan energy and conditioned air savings. By deploying smart sensing technology, both the exhaust and supply fans can be controlled to capitalize on the affinity laws for motor energy savings, reduce makeup air heating and cooling energy, increasing safety, and reducing ambient kitchen noise levels.[33] - Source: Internet
  • Natural ventilation is the ventilation of a building with outside air without using fans or other mechanical systems. It can be via operable windows, louvers, or trickle vents when spaces are small and the architecture permits. ASHRAE defined Natural ventilation as the flow of air through open windows, doors, grilles, and other planned building envelope penetrations, and as being driven by natural and/or artificially produced pressure differentials.[2] - Source: Internet
