As such, it … The evaporator which is the another heat exchanger used in AC takes heat from the passenger’s cabin which in turn converts the liquid refrigerant flowing through the evaporator into vapors which in turn provide cooling with the help of the blower fan. As the Freon goes through the expansion valve it returns to a low-pressure gas and rapidly cools in the evaporator. Unfortunately changing the heater core is usually not the easier job in the world as engineers tend to squeeze them into some pretty tight spaces under the dash. As we have already mentioned that air conditioning system inside a cabin is required to provide a relaxed and fatigue free atmosphere to the humans which in turn provides comfort which is essential for the health of a human being. The reduction in size of compressors and motors helps batteries run them with less energy, but materials research is playing an increasing role in development at the molecular level. For an excellent understanding about the working of a car AC system watch the video given below: Note – Between evaporator and compressor a receiver dryer is used that convert the remaining liquid refrigerant from the evaporator into the vapors before sending it to the compressor.
