how does air handler unit work

The air handler also may include the heating or cooling coils. An air handler, or air handling unit (often abbreviated to AHU), is a device used to condition and circulate air as part of a heating, ventilating, and air-conditioning (HVAC) system. Components of Air Handling Unit. Here are some of the air handling unit components that may be contained in the equipment. In the worst case, the mismatched system may not work at all. Air Handler. The unit in question can be shut down, while the other units can operate independently so that cleanliness of the space is maintained. There, the metal fins on the coil absorb and disperse the heat, and the condenser fan blows the exhaust away from the building. Filter section 5. (Refer to the picture below) Yet as recently as 1993, only 68 percent of houses in the United States had some cooling equipment, either window air conditioners or central AC systems. This cold gas is then pumped into the evaporator coils. This term stands for Heating, Ventilation and Air Conditioning. The blower fan moves the air through the ductwork. Plus, Trane air handlers make a significant contribution to the overall efficiency of your system. Whereas the fridge or freezer works to cool or freeze items within itself, and air conditioner works to cool the air around it. At the core of the Air exchange there are small passage ways where the air gets warmed up with the stale air from inside the home. Fan filter units are not only easy to service and maintain as needed, but also produce a much lower noise floor when in operation. When the thermostat called for heat a burner was ignited, the fan started and it heated the area that was being controlled. Air conditioning units work in a similar manner to fridges and freezers but with one critical difference. An improperly functioning air handler can affect the efficiency with which an HVAC unit operates and one that is nonfunctional can cause the HVAC system to stop working completely. It is preferred that the occupied and non-occupied areas and spaces have smoke detectors simply because the fans in air handlers or that move air through duct work may not be operational at all times so having smoke detectors in the duct work will not offer the amount of protection that smoke detectors would offer in the spaces or area served whether those areas or spaces are occupied or not. The heat dissipates outdoors by the coil in the condensing unit. Different types of motors. The evaporator coil is usually inside an air handler (indoor) unit normally installed on the furnace. Air conditioners in cars. If you combine a condensing unit with an air handler (or furnace) it wasn’t designed to work with, in the best case the result will be reduced operating efficiency. The stale air gets sent to the outside while the new air is sent to the inside. Motor section 6. The ions may be spread through the room, or they can be generated on the surface of a catalytic plate inside the unit. The air handler is in the attic and about two months after installation, we saw water damage in the ceiling. Car air conditioners work much the same way as home and office ones, only they're a lot smaller. It is essential to any AC unit and heating forced air system. The air handler works with the outdoor unit (a condenser or heat pump) in a typical split-system by using refrigerant lines that connect the two systems. Central air conditioning, forced air furnaces and heat pumps all use air handlers. Since it was not a major problem, we waited a couple of months before the guy returned to the area. How Does a Rooftop Unit Work? The main difference is that the air handlers only circulate heat when paired with a heat pump. With an air conditioner, the heat rises and as it does the air passes through coolant coils transferring the heat out. Drain Pans and Lines. Blower section 2. Just like a furnace, air handlers contain a blower (fan), controls, and an evaporator coil that conditions and recirculates the air in your home. An air handler is usually a large metal box containing a blower, heating or cooling elements, filter racks or chambers, sound attenuators, and dampers. It can be a part of your furnace and houses the evaporator coils, the blower motor, and some HVAC controls. An air handler, or air handling unit, is the indoor part of an air-conditioning or heat pump system. Traditional HVAC systems, such as variable air volume (VAV) systems serving multiple zones, have potential problems in terms of poor thermal comfort and possible microbial contamination. So, since that shouldnt require much work, I climbed up there and on the air handler it says: Fan Coil Unit Mod NFCX 600CC3 Style FCX 6000C "MARK ELECTRIC HEATER ACCESSORY AS INSTALLED" tHEN, IT HAS KIND OF A TABLE WITH VALUES, UNDER "mark #". Unlike a dedicated air handling unit, filter servicing does not require shutting down an entire system. The cold side consists of an expansion valve and a cold coil, and it is usually part of your furnace or some type of air handler. The compressor uses electricity as its source of power to pump the refrigerant across the system collecting indoor heat and removing it from the home. They come in a variety of sizes and usually last 10 to 15 years. What does your outside air conditioner unit do? However, the current needs of comfort and hygiene are leading some manufactures to supply the units with ionizer also. In addition to the electrical components and a fan, a heat pump system includes: Compressor - Moves the refrigerant through the system. Heat Pump + Air Handler Matched Systems ... HOW IT WORKS: CENTRAL AIR AND SPLIT SYSTEMS. How Do They Work? Once a rooftop AC unit is installed, cool, low-pressure refrigerant arrives at the compressor as a gas and then compresses into a hot, high-pressure gas as it flows into the condenser coil. Then this cool air is routed throughout your home by means of a series of air ducts. Or, it may appear to run initially and then fail after a short time. How does an AC induction motor work? The ionizer is an additional filters currently the one of the most advanced air-cleaning technologies in the world (COLD PLASMA). In all these systems, a single air handler is usually responsible for both heating and cooling.
