Description

Cold/hot wind type solar absorption air conditioner

1. Technical field

The utility model relates to a solar air conditioning device, which is a cold/hot wind type solar absorption air conditioning device.

2. Background technology

Solar energy is abundant, cheap and clean energy. The intense radiation of the sun in summer coincides with the need for cooling. Therefore, using solar energy instead of conventional energy to drive absorption refrigerators for cooling, and using solar radiation for auxiliary heating in winter can not only maximize the use of clean natural resources, but also have important energy-saving and environmental protection effects. At present, all countries in the world are stepping up the research and technological development of solar air conditioners. Many countries have established or are establishing solar air conditioning systems. At present, most solar absorption air conditioning systems are mainly composed of solar collectors, absorption refrigerators, heat storage tanks, cooling towers, air conditioning boxes and auxiliary heating systems. However, the heat transfer between the refrigerant and the air in the existing solar absorption air conditioner can only be realized through two heat transfers: the refrigerant catches the cold water and the cold water catches the air twice. Due to the need for two heat transfers, it will cause excessive temperature difference loss and low cooling efficiency. Moreover, the absorption refrigerating machines used are usually industrial-scale chillers with complex structures, high costs, and inconvenient maintenance. The generation of cold air also needs to be realized with the help of the matching air conditioning box or fan coil. It is too complicated to be convenient for the vast urban and rural residents' houses to use.
