Refrigerant is a general name given to a group of chemicals such as hydrofluorocarbons (HFCs), ammonia, propane, and carbon dioxide. why R32 is the best refrigerant for air conditioners, why copper pipes are used in air conditioning. Distributing the air to each and every corner of room. The refrigerant in an air conditioner goes through 4 processes which are compression, condensation, expansion, and evaporation. The temperature of the final liquid is . The blower sucks the room air inside where the thermostat takes the temperature reading. The heat energy from a room always absorbed by the cold refrigerant and carry away from the room. This cooled fresh air isthen mixed With the room air. The evaporator coil is the station located indoors and absorbs heat from the air, cooling the air. Its compression power is what pushes the refrigerant to circulate between the indoor unit and the outdoor unit of an air conditioner. No other materials are more suitable than copper. Then the refrigerant travels back indoors and enters the evaporator coil. To maintain the purity of air inside the room, fresh outdoor air is made to enter into the room through air damper. It is possible for air conditioners to make the air too dry? Evaporation is a process where the liquid turns back into gas. Like split systems, packaged systems pull warm air from the home, through return air ducts, into its evaporator coil section. For inverter type, one extra signal cable is required for the indoor unit. In a window air conditioner, air filter is located on the air entering side of evaporator coil. Window air conditioning system consists of following components: Al the above mentioned components are briefly discussed in the following manner. The condenser coil is located at the outdoor unit while the evaporator coil is located at the indoor unit of an air conditioner. Air conditioning systems work very much in the same way as your standard refrigerator . The pipe running from the condenser (outdoor unit) to the evaporator (indoor unit) is often called the liquid pipe because the refrigerant is in liquid form when traveling inside the pipe. During condensation, heat is extracted from the refrigerant gas, the enthalpy or the energy of the refrigerant gas drops, no change in pressure. In a traditional AC, the compressor switches on and off at regular intervals. The coffee will never absorb the heat from the ambient and become hotter because it will violate the second law of thermodynamics. The filter media inside a filter drier cant be replaced, one whole piece of the filter drier has to be changed. They also can control humidity, air quality and airflow within your home.
