Central air conditioning has two main components: condenser and evaporator.
In most air-conditioning units, the condenser can be found outside the house or office building. The evaporator coil is usually installed in the connection of the main duct located inside the building. The function, maintenance, repair and maintenance of air conditioning are crucial to the overall output and operation of air conditioning.
Most central air-conditioning units use a split system. In other words, they are made up of one side of the "hot", or condensation, including condensation, compressor and fan - it is at your house, there is another side of the "cold", it is located in your home. A cold surface consists of an expansion valve and a cold disc, usually part of a furnace or some type of air handling unit. The furnace blows through the coil of the evaporator, which cools the air. The cold air then passes through a series of air ducts in your home.
The evaporator coil is a series of pipes connected to a furnace or air handling unit that blows indoor air through the coil to absorb heat from the air. The cooled air is piped to the room. Then the refrigerant returns to the compressor and the cycle begins again. Read more about the evaporator coil.
