An air conditioner's compressor drives the heat-transfer process that cools rooms. An air conditioner works by transforming a refrigerant compound from a gas to a liquid and back again in a continuous cycle. Air conditioners consist of four basic mechanical parts: a compressor, condenser, expansion valve and evaporator. Compressor's Function The compressor is the heart of the cooling cycle. The cycle begins when the compressor draws in cool, low-pressure refrigerant gas from the indoors. The motor-driven compressor’s sole function is to "squeeze" the refrigerant, raising its temperature and pressure so that it exits the compressor as a hot, high-pressure gas. Heat Transfer The compressor pushes the hot gas to the finned condenser coil in the outdoor side of the air conditioner where fans blow cool outside air over the coil and through the fins, extracting the heat from the refrigerant and transferring it to the outside air. Turns Liquid When enough heat has been extracted from the refrigerant, it condenses into a warm liquid that passes under high pressure to an expansion valve that turns the refrigerant into a cool, low-pressure liquid.

The refrigerant goes from the expansion valve to the finned evaporator coil located in the indoor or room side of the air conditioner unit. cost of replacing outdoor ac unitAbsorbs Heat When the refrigerant enters the evaporator coil where the pressure is much lower, it is chemically compelled to evaporate into a gas. emergency ac unitThis process requires heat, which comes from the room's warm air being blown over the evaporator coil by another fan. ac unit direct reviewsAs room heat is transferred to the evaporating refrigerant, the room's air grows cooler. The refrigerant, now back to a cool, low-pressure gas, is drawn back into the compressor to continue the cycle.

Just seems to cool the area in front of the unit not to the left & rig 2 Why is the vent hose so hot? 2 Can the window frame be adapted to work with windows that open up from the side(swing open like a door?)Compresses the refrigerant from low pressure (low temperature) to high pressure (high temperature). This conversion raises the boiling point to higher temperature levels, facilitating elimination of the heat brought by the outdoor air. This component receives gas at high pressure and high temperature from the compressor. In air-cooled condensers, the metallic surfaces cool the gas which changes status and turns to liquid. In the case of water-cooled condensers, it is the circulation of the water that produces the same cooling effect.

When the refrigerant evaporates in the evaporator, it absorbs heat from the surrounding air and produces cooled air. A narrowing of the tube connected along the line between the condenser and the evaporator with diameters ranging from 1 to 2 mm. and lengths ranging between 1 and 2 m, allows the adjustment of the amount of gas fed to the evaporator. Electric and electronic components needed by the various air conditioner functions. It exhausts air from the indoor environment and conveys it through the evaporator; the air is now cool and distributed back into the environment. This causes the air to circulate through the condenser in order to cool the refrigerant. 1 Additional Year of Protection 1-Year Housewares Extended Protection Plan See price in cart Frigidaire 5,000 BTU 115V Window-Mounted Mini-Compact Air Conditioner with Full-Function Remote Control To see our price, add these items to your cart.
