Hang Zhou Dawn Air Conditioning Co .,Ltd.

In most average air conditioning units, the condenser can be found outside the house or office building. The evaporator coils are usually found mounted in the junction of the main duct on top of the furnace which is located inside the building. The function, maintenance, repair and upkeep are of the most vital importance to the overall output and workings of the air conditioner.
Most central air conditioning units operate by means of a split system. That is, they consist of a "hot" side, or the condensing unit—including the condensing coil, the compressor and the fan—which is situated outside your home, and a "cold" side that is located inside your home. 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 furnace blows air through an evaporator coil, which cools the air. Then this cool air is routed throughout your home by means of a series of air ducts.
The evaporator coil is a series of piping connected to a furnace or air handler that blows indoor air across it, causing the condenser coils to absorb heat from the air. The cooled air is then delivered to the house through ducting.
