太阳·空气热源热泵系统是在传统的空气热源热泵系统的基础上,利用太阳能热源而新开发的系统。它可以制冷、供热、供生活热水,是一种利用自然能源、无污染、适用性广、效率高的新型冷热源系统。一、系统的构成及原理由压缩机组、冰(水)蓄热槽、设在屋顶上的集热/放热板及冷媒管道组成,制冷工况见图1。1.制冷工况运行原理制冷运行是在夜间进行,一是利用夜间电力(较白天便宜一半);二是利用设在屋顶上的放热板在夜间向室外散热。冷媒首先通过压缩机成为高温高压气体,然后通过屋顶上的放热板向夜空辐射、对流放热后成为液体,再通过膨胀阀变成低压低温液体进入冰蓄热槽的盘管进行制冰蓄冷。蒸发后的冷媒又成为气体返回压缩机,如此反复,形成制冷循环。在夜间制得的冷贮存到
The solar air heat source heat pump system is a newly developed system using a solar heat source based on a conventional air heat source heat pump system. It can be used for cooling, heating, and domestic hot water. It is a new type of cold and heat source system that uses natural energy, no pollution, wide applicability, and high efficiency. 1. The composition and principle of the system consists of a compressor unit, an ice (water) heat storage tank, and a collector/heater plate and a refrigerant pipe on the roof. The cooling conditions are shown in Figure 1. 1. Refrigeration operating principle Refrigeration The operation is carried out at night. The first is the use of nighttime electricity (half the cost of daylight) and the second is the use of a radiator plate on the roof to dissipate heat outdoors at night. The refrigerant first passes through the compressor and becomes high-temperature and high-pressure gas. Then it radiates into the night sky through the heat release plate on the roof, convection heats up and becomes liquid, and then becomes a low-pressure, low-temperature liquid through the expansion valve into the coil of the ice thermal storage tank for ice storage and cold storage. . The vaporized refrigerant returns to the gas and returns to the compressor. This repeats the refrigeration cycle. Cold storage made at night
