This air conditioning unit requires the introduction of the outboard air (100%) anti-temperature dehumidification and sterile air. The temperature and humidity are controlled by the temperature and humidity control system to supply clean air to each room after treatment by the sterile filter box, and the air vented from the Room is deodorized, removed from the filter box, and released to the outside. The outdoor air (100%) temperature and humidity control is a heat pump type cooling system (cooling, heating, and dehumidifying) that provides multiple control of precision cooling, dehumidification, and heating with proportional control depending on the environmental conditions of the four seasons.
