The most common and cost effective cooling device is the room AC Split. This consists of indoor and outdoor portions . An air filter, a fan and a cooling coil are segments of the indoor portion. The warm air is drawn through the filter and into the fan then blown over the cooling coil. The cooling coil then cools and moistens the air before it is blown into the room. The cooling coil contains a refrigerant fluid, which converts its physical condition from liquid to gas because heat from the warm air passing over the coil causes its evaporation . The outdoor portion of the unit consists of a compressor, a fan and a condenser. The cooling coil gives off low-temperature and low-pressure refrigerant gas to the compressor. The compressor on the other hand delivers high-temperature and high-pressure refrigerant gas to the condenser. Inside the condenser the high temperature, high pressure refrigerant gas is converted to refrigerant liquid. Heat from the hotter refrigerant gas is taken by the cooler outdoor air passing over the condenser.

This process causes the refrigerant gas to change to the liquid state. The refrigerant fluid circulates through the closed path leading through the cooling coil, the compressor and the condenser in a constant motion. The comparatively cool outdoor air is sucked by the fan for cooling the condenser and then blows the hotter air back outdoors. In a room air conditioner, electric motors operates the compressor and the two fans. The whole small residence can be cooled by some room air conditioners with sufficient capacity.

Although a room air conditioner as Elektronik equipment is the lowest-cost cooling device, it has its own drawbacks which contain the following: the majority of room units can provide only widely irregular room air temperature; most room air conditioners work with noise; it is hard to obtain an even distribution of cool air.

Because of the known drawbacks of a room air conditioner many people prefer to use the more expensive central cooling system.

A central cooling system is commonly consists of two parts : An indoor and an outdoor unit. A filter, a fan and a cooling coil compose the indoor unit. The outdoor unit on the other hand contains a compressor that is motor-driven, a fan for the condenser and a condenser. A cabinet mounted outdoors homes these components . Most home cooling systems provide humidity reduction but offer only very limited humidity control. The length of the compressor work determines the moisture content reduction . For instance , a low indoor dampness value of 40 percent is reached when the compressor operates permanently for several hours throughout a hot summer day, but as night time comes up and the compressor stops working , the water drops on the cooling coil tend to condense and a jump in the indoor humidity occurs . This variable moisture and its limited control however, are suitable for home owners who are using the central cooling system.
