What is the difference between an evaporator and a condenser?

Evaporators and condensers have different functions. The evaporator is used to absorb heat, and the condenser is used to discharge heat. Both the evaporator and the condenser are important components in car air conditioners. Air conditioning is an important comfort feature in a car. It can be used for both cooling and heating. When using a car in winter and summer, air conditioning is used almost every day. The refrigeration principle of car air conditioners is relatively simple. When the car air conditioner is cooling, the compressor clutch will engage. At this time, the engine will drive the compressor to run. When the compressor is running, it can continuously compress the refrigerant and deliver it to the evaporator. The refrigerant can expand and absorb heat in the evaporator, so that the refrigerant can cool the evaporator. The cooled evaporator can cool the wind blown by the blower, so that the car air conditioner can blow out cold air. The heating principle of car air conditioners is even simpler. During heating, the high-temperature coolant in the engine will flow through the heater water tank. At this time, the wind blown by the blower will also pass through the heater water tank, so that the air outlet of the car air conditioner will flow through the heater water tank. Warm air can be blown out. Car air conditioners need to be cleaned and disinfected regularly. If they are not cleaned for a long time, a lot of bacteria will breed inside the car air conditioning system, which is harmful to the health of passengers in the car.
