1. The seasonal adaptability of solar air conditioners is good. That is to say, the cooling capacity of the system increases with the increase of solar radiant energy, which just meets the urgent requirements of people for air conditioners in summer.
2. The traditional compression refrigerator uses Freon as the medium, which has a great destructive effect on the atmosphere, while the solar air-conditioning refrigerator uses non-toxic and harmless water or lithium bromide as the medium, which is very beneficial to environmental protection.
3. The household solar air-conditioning system can combine summer cooling, winter heating and hot water supply in other seasons, which significantly improves the utilization and economy of the solar system.
1. At present, most of the solar air conditioners that have been upgraded are large-scale lithium bromide refrigerators, which are only suitable for central air conditioners in units, and household solar air conditioners are far from popular.
2. Due to the low solar irradiance under natural conditions, the ratio of the collector lighting area to the air-conditioning building area is restricted. Currently, it is only suitable for buildings with a small number of floors.
3. Although solar air conditioners can greatly reduce the consumption of conventional energy and greatly reduce operating costs, the initial investment of the current system is still high and only suitable for a limited number of wealthy users. Many units and families do not have the economic ability to use solar air conditioners. .
