Energy problems are of great concern, and energy conservation and consumption reduction are important points of human attention. Solar energy is both a primary energy source and a renewable energy source. The energy-saving environment-friendly energy-saving vehicle is rich in resources, free to use, free of transportation, free of any pollution to the environment, and capable of being well utilized, and greatly influencing energy conservation. Radiant refrigeration has received increasing attention in recent years because it can provide "free cooling" to buildings, helping to reduce the energy consumption of conventional air conditioning systems. Recently, a radiation refrigeration film has been proposed which radiates heat to the outside space through an "atmospheric window" (8-13 um band) and reduces the surface temperature of the film to below ambient temperature by radiation heat exchange.

The air conditioning system takes a drying agent with strong moisture absorption capability and water as transfer media, the drying agent and the water are placed in a closed container, water vapor is quickly absorbed by the drying agent in the closed atmosphere to cause the water in the container to quickly volatilize and gasify, and the gasification of the water can absorb a large amount of heat in the environment to generate a refrigeration effect. Compared with the patent CN109631209A and the patent CN109489167A, the invention is a brand new device, the efficiency of the system or the equipment is improved by obtaining cold energy through heat exchange between the radiation refrigeration film and the atmosphere, the solar heat collection technology obtains heat, the natural cold source is fully utilized, a large amount of energy sources can be saved, and the energy conservation concept of a green building is met; simultaneously, this patent can realize supplying the switching between cold mode and the heat supply mode through the cooperation between each subassembly, also can adjust the switch of each valve and water pump, adopts the air supply mode of various different modes, and is simple and convenient.
