technical field

Background technique

The total heat exchange air conditioner is a total heat exchanger, which is a kind of outdoor fresh air that is filtered, purified, and sent into the room after heat exchange treatment. A high-efficiency, energy-saving and environmentally friendly high-tech product whose temperature is basically not affected by fresh air.
