It also cleans the air and controls the moisture level. An air conditioner is able to cool a building because it removes heat from the indoor air and transfers it outdoors. A chemical refrigerant in the system absorbs the unwanted heat and pumps it through a system of piping to the outside coil. The fan, located in the outside unit, blows outside air over the hot coil, transferring heat from the refrigerant to the outdoor air. Basic Operations. Most air conditioning systems have five mechanical components: a compressor an expansion valve or metering device an evaporator coil and blower a chemical refrigerant. 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. A window unit operates on the same principal, the only difference being that both the hot side and the cold side are located within the same housing unit. The compressor (which is controlled by the thermostat) is the "heart" of the system. The compressor acts as the pump, causing the refrigerant to flow through the system. Its job is to draw in a low-pressure, low-temperature, refrigerant in a gaseous state and by compressing this gas, raise the pressure and temperature of the refrigerant. This high-pressure, high-temperature gas then flows to the condenser coil. The condenser coil is a series of piping with a fan that draws outside air across the coil. As the refrigerant passes through the condenser coil and the cooler outside air passes across the coil, the air absorbs heat from the refrigerant which causes the refrigerant to condense from a gas to a liquid state. The high-pressure, high-temperature liquid then reaches the expansion valve. The expansion valve is the "brain" of the system. By sensing the temperature of the evaporator, or cooling coil, it allows liquid to pass through a very small orifice, which causes the refrigerant to expand to a low-pressure, low-temperature gas. This "cold" refrigerant flows to the evaporator. The evaporator coil is a series of piping connected to a furnace or air handler that blows indoor air across it, causing the coil to absorb heat from the air. The cooled air is then delivered to the house through ducting. The refrigerant then flows back to the compressor where the cycle starts over again. Perfect comfort all year round - How air-conditioning works Air-conditioning is an ingenious way of controlling not only the temperature but also the movement and cleanliness of air inside the building. Although the process is relatively complex, the operation itself is quite simple. In most systems each indoor unit is connected by inconspicuous pipe work to an outdoor unit attached to a wall, rooftop or balcony, or located in a plant room. Not just cooling but heating - Lower heating bills Air-conditioning was originally considered a cooling system. Then with the introduction of the split heat pump, air-conditioning was able to provide hot air for winter as well as cool air in the summer, ensuring optimum conditions all year round. Good for business - Better productivity Only a few years ago air-conditioning was considered as a luxury in the UK. Today many businesses regard it a necessity. In air-conditioned offices, staff work more productively and managers make better decisions.
