Principles of Electric Vehicle Air Conditioning System

Electric vehicle air conditioners rely on heat pumps or electric heaters for heating. The refrigeration principle of air conditioner:

On electric vehicles, after pressing the ac button, the electric ac compressor will start to work, so that the electric car compressor can continuously compress the refrigerant and deliver the refrigerant to the evaporating box. The refrigerant expands and absorbs heat in the evaporating box, so that the refrigerant can cool the evaporating box, and the cooled evaporating box can cool the wind blown by the blower, so that the air outlet ac vent of the air conditioner can blow cold air.

The heating of the air conditioner of gasoline vehicles relies on the high-temperature coolant in the engine. After turning on the warm air, the high-temperature coolant in the engine will flow through the heating water tank. At this time, the air blown by the blower will also pass through the heating water tank. Warm air can be blown out from the air outlet.

Electric cars are different. Most electric cars rely on electric heaters to achieve heating. The electric heater is equivalent to the warm air water tank. After the electric heater is turned on, the wind blown by the blower will pass through the electric heater, so that the air outlet of the air conditioner can blow out warm air.

The working principle of the heat pump is more complicated, but the heat pump is driven by an electric motor, and the heat pump air conditioner can cool and heat.

The car’s air conditioning system should be cleaned and disinfected regularly, otherwise a lot of bacteria will grow inside.
