How A Room AC Works
The most widespread and cost efficient cooling device is the room Air conditioner. This includes inner and outer portions . An air filter, a fan and a cooling coil are pieces 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 includes a refrigerant fluid, which changes its physical condition from liquid to gas because heat from the warm air going over the coil causes its evaporation . The outer portion of the unit consists of a compressor, a fan and a condenser. The cooling coil provides low-temperature and low-pressure refrigerant gas to the compressor. The compressor on the other hand brings high-temperature and high-pressure refrigerant gas to the condenser. Within the condenser the high temperature, high pressure refrigerant gas is modified 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 goes through the closed path leading through the cooling coil, the compressor and the condenser in a permanent 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 engines drive the compressor and the two fans. An entire small residence can be cooled by some room air conditioners with sufficient capacity.
Though a room air conditioner as Elektronik equipment is the cheaper cooling device, it has its own drawbacks which contain the following: the majority of room units can give only widely irregular room air temperature; most room air conditioners operate with noise; it is hard to obtain an even distribution of cool air.
Because of the known drawbacks of a room air conditioner a lot of people would like to use the more expensive central cooling system.
A central cooling system is commonly consists of two units : An indoor and an outdoor unit. A filter, a fan and a cooling coil constitute 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 houses these components . Most home cooling systems provide humidity decrease but offer only very limited humidity control. The length of the compressor work determines the moisture content decrease . For instance , a low indoor dampness value of 40 percent is reached when the compressor works permanently for several hours during a hot summer day, but as night time approaches and the compressor stops working , the water drops on the cooling coil tend to evaporate and a jump in the indoor dampness occurs . This variable moisture and its limited control however, are acceptable to home owners who are using the central cooling system.
