Solar air conditioner

Abstract

The invention discloses a solar air conditioner comprising a solar heat collector (1) and at least one application terminal. An inlet end and an outlet end of the solar heat collector (1) are connected with a first circulation loop. A fist working medium flows in the first circulation loop, and the application terminals are connected on the first circulation loop. On the same condition, boiling point of the first working medium is higher than or equal to that of water. By the structural design of the solar air conditioner, on one hand, technical construction difficulty of the air conditioner can be reduced, and on the other hand, the advantage of the solar heater collector that high temperature can be achieved can be utilized sufficiently, so that cooling and warming of the air conditioner can be improved evidently.

Description

technical field [0001] The invention relates to the technical field of solar energy, in particular to a solar air conditioner. Background technique [0002] The biggest feature of the solar air conditioner that combines solar energy with air conditioners is that it matches well with the seasons, because the better the sun in summer and the hotter the weather, the greater the cooling capacity of the solar air conditioner system. However, there is no mature product of solar air-conditioning in the existing market. One of the reasons is that the cost of existing solar air-conditioning systems is relatively higher than that of mainstream electric air-conditioners; Conversion ratio, referred to as energy efficiency ratio) is not high; moreover, the comprehensive utilization rate of the existing solar air-conditioning system is low and cannot adapt to different application requirements. [0003] The patent No. "01128404.8" discloses a solar air conditioner. In this solar air con...

Problems solved by technology

[0005] In this system, water is used as the circulation medium of the heat collection system. Under normal temperature and pressure, the maximum temperature of the medium water to maintain a liquid state is only 100 degrees Celsius. However, in order to improve work efficiency, the temperature of the water medium to maintain a liquid state needs to reach 150-200 degrees Celsius. In order to achieve this purpose, it is necessary to pressurize the circulation pipeline to increase the boiling point of the medium water; however, due to the pressure in the circulation pipeline, it increases the difficulty of technical implementation

In addition, for medium and high temperature heat collection systems, especially trough collectors, the temperature can reach more than 300 degrees Celsius, and even if the temperature of the water medium can reach 150-200 degrees Celsius under pressurized conditions, it still cannot make full use of this Advantages of medium and high temperature heat collection system

Furthermore, the refrigeration unit needs to be matched with the solar heat collection system to improve the COP of the entire system, and the solar air conditioning system cannot effectively solve the problem of heat source stability caused by changes in solar conditions
