There's only air. @134 Working principles of car air conditioning systems. It is a vapor or gas compression refrigeration system. The compressor (COMPRESSOR) will act to suck the refrigerant from the evaporator (EVAPORATOR) refrigerant. At that time it still existed as a gas and compressor. It also serves to compress the refrigerant into the condenser (CONDENSER), causing the refrigerant to increase in temperature and pressure. When the refrigerant flows through the condenser, the temperature drops. The refrigerant will then continue to flow. Receiver/Dryer (RECEIVER/DRYER) to filter dirt and moisture contaminants in the refrigerant flowing to application valve (EXPANSION VALVE) and then inject it as a fine mist into Evaporator This causes the refrigerant to have a low pressure and absorb heat from the outside. to achieve a gaseous state Makes the outside temperature drop. After that, the gas refrigerant It will be sucked into the compressor. to start working again Keep repeating
