Roof type air conditioning system based on solar energy and waste heat recovery

Abstract

The invention discloses a roof type air conditioning system based on solar energy and waste heat recovery. The roof type air conditioning system based on solar energy and waste heat recovery can work under summer working conditions, winter working conditions and transition season working conditions. Under the summer working conditions, fresh air enters an efficient plate type heat exchanger, waste heat of exhaust air is obtained and is then mixed with indoor return air, and then cooling treatment is carried out through a surface type air heat exchanger to enter a room through an air supply pipe and an air supply outlet; and the exhaust air enters the efficient plate type heat exchanger through an air conditioner room air return opening and an air return pipeline, and waste heat is transferred to the fresh air and is then discharged to the atmosphere. Under the winter working conditions, fresh air is preheated for one time through an enhanced solar air heater, and then the fresh air is subjected to secondary preheating by waste heat of exhaust air through the efficient plate type heat exchanger and is then mixed with indoor return air, and finally, heating treatment is carried out through the surface type air heat exchanger and then enters the room through an air supply pipe and an air supply opening. Under the transition season working conditions, the system operates with totally fresh air. Under the summer working conditions, the winter working conditions and the transition season working conditions, the opening and closing of a fresh air opening are converted by an intelligent controller. The roof type air conditioning system based on solar energy and waste heat recovery has the advantages of being energy-saving, environment-friendly, compact in structure, low in noise, high in automation degree and the like.

Description

technical field [0001] The invention relates to the technical field of waste heat recovery air conditioning equipment and the application of clean solar energy resources, in particular to a rooftop air conditioning system based on solar energy and waste heat recovery. Background technique [0002] As people's requirements for indoor environment comfort gradually increase, air-conditioning systems have been widely used. For the air-conditioning systems in multi-storey or single-storey buildings such as lecture halls, multi-functional halls, shopping malls, exhibition halls, theaters, factories, stadiums, etc., due to the high density of people, the fresh air volume of the air-conditioning system is required to be large, so the air-conditioning system can higher consumption. In order to maintain the balance of indoor air volume, the air conditioning system in these places also has a large exhaust air volume. If it is directly exhausted, a lot of cold and heat will be wasted. ...

AI Technical Summary

Problems solved by technology

[0003] The present invention aims at the problems of high energy consumption of fresh air, waste of exhaust air energy and inability to use fresh air for cooling in the prior art, and provides a roof-type air conditioning system based on solar energy and waste heat recovery, that is, solar heaters, waste heat recovery of exhaust air and a new A new system integrating air cooling
