Solution 1: Adopt air-cooled heat pump units (screw/scroll) + Combined air-conditioning unit/Cabinet air-handling units. 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 rooftop air-conditioning unit to eliminate the indoor cooling and heating load. The unit integrates air cooling, heating and other functions, and meets the relatively high requirements of air volume and air pressure and relatively high requirements of temperature and humidity for large-scale stadiums. 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.
