我国建筑物采暖,耗能量大,污染严重。有关部门正积极采取措施,降低能耗,改善环境。其中,较有成效的是建造集中锅炉房和热电合产厂。本文就另一种很有前途的供热方式——热泵供热的可行性进行初步探讨。一、热泵装置的工作原理及其经济指标犹如水泵可以把水由低水位抽到高水位一样,热泵能够把热量由低温热源输送到高温需用地点。如图1所示。热泵工作时,工质(通常用氟里昂)先后要经过压缩过程1-2′;在换热器内的放热过程2′-3;通过节流阀的节流过程
China’s buildings are heating, consume large amounts of energy, and cause serious pollution. Relevant departments are actively taking measures to reduce energy consumption and improve the environment. Among them, more effective is the construction of a centralized boiler house and a heat and power plant. This paper discusses the feasibility of another kind of promising heating method, heat pump heating. First, the working principle of the heat pump device and its economic indicators Just like a pump can pump water from a low water level to a high water level, the heat pump can transfer heat from a low temperature heat source to a high temperature demand location. As shown in Figure 1. When working with a heat pump, the working medium (usually freon) has to go through the compression process 1-2′; the heat release process inside the heat exchanger 2′-3; the throttling process through the throttling valve
