The system cools the cold water in the cold water tank through the water-cooled air-conditioning main unit, and the external circulating water takes the heat of the water-cooled air-conditioning main unit out of the tunnel; the cooled cold water is pumped to the evaporator in the secondary ventilation duct to complete the air in the pipeline. Heat exchange; cooled cold air is delivered by the fan to the work area. The system uses fully automatic control technology to automatically adjust the temperature of the cold air to ensure a constant temperature at the outlet.
The water-cooled air-conditioning main unit is tailor-made and easy to install. It does not need to be equipped with matching trailers. The custom evaporator meets the installation and performance requirements of different spaces. The evaporating coil angle is adjustable, and the cold air mode and natural wind mode can be switched. The duct filter can be used repeatedly.
