Heat power type solar air conditioner

Abstract

The invention discloses a heat power type solar air conditioner which is characterized by comprising a solar thermal collector, an expansion machine system and a refrigerant circulation system. The expansion machine system comprises a first generator and a second generator, the solar thermal collector is in heat exchange connection with the first generator of the expansion machine system, and the refrigerant circulation system is in heat exchange connection with the second generator of the expansion machine system. The heat power type solar air conditioner is reasonable in structural design, can effectively low-grade heat generated by solar energy to convert and use mechanical energy and can effectively use low-grade hot water generated by the solar thermal collector to drive the expansion machine system to convert mechanical energy through heat exchange. The refrigerant circulation system is driven by the mechanical energy to meet requirements of a refrigeration air conditioner. The heat power type solar air conditioner is high in solar electric conversion efficiency and low in conversion cost and facilitates industrial application.

Description

technical field

[0001] The invention belongs to solar energy utilization technology, in particular to a thermodynamic solar air conditioner which utilizes solar heat collection to convert energy. Background technique

[0002] In the prior art, solar power generation technologies are mainly solar photovoltaic power generation or solar concentrating device array heating steam power generation, but at present, none of the above solar power generation technologies can meet the needs of industrialized large-scale production. The photovoltaic panels used in solar photovoltaic power generation are expensive, the manufacturing process is complicated, the initial installation cost is very high, and the power generation capacity is small. The material polysilicon used for photovoltaic panels will greatly pollute the environment. The array of solar concentrating devices requires a large site area, and at the same time, the conversion rate of solar concentrating to achieve high-grade he...
