Expansion: Most cars are installed in the middle behind the dashboard, which can only be seen when the dashboard is removed. The hot water tank is installed at the position where the hot water pipe behind the engine leads to the instrument.
The heater box is only a heating component in the hot air conditioning system. When the water in the engine passes through the heater box, the heater box is heated, and the fan works to blow air against the heater box. When the wind passes through the warm air trough, it is the warm air coming out of the air outlet.
Condenser is a heat dissipation component in cold air conditioning system. Just like the water tank, it is used for cooling water, and the condenser is used for cooling refrigerant. Its heat dissipation directly affects the air conditioning effect.
