how does air handler unit work

An air handling unit where (1) is the supply air, (2) fan section, (3) vibration isolator, (4) cooling coil, (5) filter and (6) mixed air duct. Central air conditioning, forced air furnaces and heat pumps all use air handlers. The blower fan moves the air through the ductwork. Here are some of the air handling unit components that may be contained in the equipment. UV lights for HVAC systems are designed to use a particular wavelength of light — 254 nanometers — that is absorbed by the DNA of microorganisms. 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. Air Handlers - An air handler is usually located in the garage, a closet, or in the attic (unless you have a package unit then the air handler is incorporated into one system). All AC units need an air handler or way to move air. 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. The two-stage condenser works as follows: During off-peak times, including morning and evening times in the summer, the unit will typically run in low-stage approximately 70% lower capacity. 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. With an air conditioner, the heat rises and as it does the air passes through coolant coils transferring the heat out. How Does a Rooftop Unit Work? Any air conditioning unit has filters that clean the air from dust, odors, microorganisms etc. Packaged Heat Pumps: A packaged heat pump uses heat pump technology to cool and heat your home. Here's a little animation to summarize things and hopefully make it all clear: Two pairs of electromagnet coils, shown here in red and blue, are energized in turn by an AC supply (not shown, but coming in to the leads on the right). Air Handler. Blower section 2. An air handler, or air handling unit, is the indoor part of an air-conditioning or heat pump system. In all these systems, a single air handler is usually responsible for both heating and cooling. 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. Problem: We had a brand new air conditioning unit installed about 9 months ago. The two red coils are wired in series and energized together and the two blue coils are wired the same way. Getting the Heat Out. HVAC systems are designed to heat or cool the air, but they usually dehumidify the air as well. Air conditioning units work in a similar manner to fridges and freezers but with one critical difference. In this way, blower fans work to aid the heat transfer by sucking the warm air out of the room to blow over the coolant, maximizing the quantity of airflow. 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. With properly sized Trane air handlers, your family has the right amount of clean, comfortable air all year round. The outside unit is where the refrigerant dumps all the heat it pulled from your home’s air. 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. 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. Duct system 3. More than any other technology, air-conditioning has transformed how we live and work—and where we live and work. Unlike a dedicated air handling unit, filter servicing does not require shutting down an entire system. The heat pump works in conjunction with the air handler to distribute the warm or cool air to interior spaces. They come in a variety of sizes and usually last 10 to 15 years. A ductless mini-split air conditioner works like a regular central air conditioner but without the ducts.. How’s that possible? Car air conditioners work much the same way as home and office ones, only they're a lot smaller. 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. How does an ionisation filter work? In addition to the electrical components and a fan, a heat pump system includes: Compressor - Moves the refrigerant through the system. This offers greater, cost-efficiency and allows the unit to cycle long enough to properly dehumidify the home. 2. The indoor unit blows warm air from your home over cold evaporator coils. Now, more than 87 percent of houses are so equipped. 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. Air handlers connect to an air conditioner or heat pump to provide cooled or heated air for an indoor space. Just like a furnace, air handlers contain a blower (fan), controls, and an evaporator coil that conditions and recirculates the air in your home. Then this cool air is routed throughout your home by means of a series of air ducts. Usually, an air handler is a large metal box containing a blower, heating and/or cooling elements, filter racks or chambers, sound attenuators, and dampers. Heat Pump + Air Handler Matched Systems ... HOW IT WORKS: CENTRAL AIR AND SPLIT SYSTEMS. Whereas the fridge or freezer works to cool or freeze items within itself, and air conditioner works to cool the air around it. The evaporator coil is usually inside an air handler (indoor) unit normally installed on the furnace. Drain Pans and Lines. Air conditioners in cars. The ionizer is an additional filters currently the one of the most advanced air-cleaning technologies in the world (COLD PLASMA). The system contains an outdoor unit that looks similar to an air conditioner and an indoor air handler. 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 #". This term stands for Heating, Ventilation and Air Conditioning. When the furnace is electric, a blower is included in the system. Filter section 5. … There, the metal fins on the coil absorb and disperse the heat, and the condenser fan blows the exhaust away from the building. Older heating units from the 1950s through to the late 1970s were generally a simple unit that consisted of a heater only. They do this by moving all the warm air from inside an area to the outside and then circulating cooled air back into the space. Components of Air Handling Unit. Packaged Air Conditioners: The compressor, coils, air handler are all housed in a single-boxed cabinet. 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. The main difference is that the air handlers only circulate heat when paired with a heat pump. The air conditioner in a central heating and cooling system provides cool air through ductwork inside your home, by providing a process that draws out the warm air inside, removing its heat. Traditional air conditioning units consist of a compressor and condenser that cycles the cooled refrigerant through a box called an "air handler" in the building's ventilation system, using the fan in the furnace to force cooled air through the duct work to existing vents. When the thermostat called for heat a burner was ignited, the fan started and it heated the area that was being controlled. 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. They may use refrigerant, chilled water or hot water to treat the air. In the worst case, the mismatched system may not work at all. The air handler includes a filter that removes particulate material from the air as it passes through. How does an AC induction motor work? Plus, Trane air handlers make a significant contribution to the overall efficiency of your system. The AHU consist of: 1. Different types of motors. Since it was not a major problem, we waited a couple of months before the guy returned to the area. 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. However, the current needs of comfort and hygiene are leading some manufactures to supply the units with ionizer also. The packaged air conditioner can also provide limited warmth by using an electrical strip heating. The air handler is in the attic and about two months after installation, we saw water damage in the ceiling.
