Solution 1: We recommend adopting water-cooled units/air-cooled scroll heat pump + Purification type combined air-conditioning unit. In summer, the air-cooled heat pump units provide the chilled water needed by terminals to satisfy the refrigeration demand; and in winter, the air-cooled heat pump provides the hot water needed by the end unit to meet the indoor heating demand.

Solution 2: Adopt direct-evaporation and purification type thermostatic and humidistatic rooftop air-conditioning unit to eliminate the thermal load indoor. The unit integrates air cooling, heating, humidifying, dehumidifying, air purification and other functions, and meets the relatively high requirements of air volume and air pressure, relatively small requirements of heating and refrigeration capacity, and relatively high precision requirements of temperature and humidity for the purification industry. The unit can be placed separately or placed in one place. The user only needs to connect the power supply, copper pipe and air duct to put it into use.
