Since heat moves from warm to cool surfaces, the heat that’s now in the high-temperature refrigerant moves to the cooler air outdoors where it can be released through the condenser. The compressor packs molecules in the gas-based refrigerant tightly together, a process which raises both the temperature and pressure of the refrigerant. To release the heat the refrigerant has absorbed, the refrigerant needs to be in a higher temperature, higher pressure form. When refrigerant leaves an air conditioner’s evaporator, it takes the form of low-pressure gas. The refrigerant travels back to the evaporator where the process begins again. The heat-filled refrigerant is pumped outdoors to the condenser unit so that the heat can be released. Coils in the evaporator unit, which are filled with a gaseous refrigerant, absorb heat. Your air conditioner pulls warm air through return air vents in rooms throughout your house. The compressor serves as a go-between between the evaporator, located inside your air conditioner, and the condenser, the unit outside your home. Air Conditioning System PartsĬentral air conditioning systems are made up of an evaporator, a condenser, and a compressor. Learn how the compressor, an essential component inside your air conditioner, functions and the maintenance required to keep it working. This also corresponds to the instructions from the compressor manufacturer Sanden specifications from the vehicle manufacturer must be observed separately in each case.Have you ever thought about how your air conditioner keeps your Whitesburg, Kentucky, home cool? An air conditioner removes heat from the air inside your home, sends the heat outdoors, and recirculates newly cooled air throughout your house. To ensure that the oil is distributed equally, the compressor must be turned 10 times by hand before installation.
The compressor must then be refilled with the entire oil quantity specified by the vehicle manufacturer (system oil quantity). For this purpose, all the oil must be siphoned off and collected.
Correct quantity of system oil in the compressor As one and the same compressor can potentially be used for different vehicles or systems, it is essential that the oil filling quantity be checked/corrected before mounting the compressor. Observe the quantity and specification of the oil Before mounting a new compressor or when refilling refrigerant oil, always check the oil quantity and the viscosity in the vehicle manufacturer’s instructions.ģ. The graphic on the right shows the average distribution of the quantities of oil within the system.Ģ. It is therefore essential to refill the appropriate quantity of oil. The oil is removed with the replaced component during repairs. Distribution of the oil There is refrigerant oil in every component of the air-conditioning system.
