摘要
二氧化碳空气源热泵是以CO_(2)作为冷媒,基于逆卡诺循环原理建立起来的一种节能、环保的制冷制热技术。系统利用压缩机做功,从自然界的空气中获取低品位热能,提供可被人们所用的高品位热能。CO_(2)热泵由于改变了传统的燃煤、燃油供热模式,电能利用率较高,因此,它与常规热泵相比,除了制冷工质更加环保以外,还可以制取高温热水,比普通空气能热泵适用范围宽,可以在较低的环境温度下工作,扩大了热泵的应用领域;CO_(2)热泵的使用与当地地质条件无关,减少了施工风险和工期,扩展了热泵的应用范围。它充分利用了可再生资源——空气的能量,替代现有的燃煤、燃气、燃油或电锅炉等传统的供热方式,减少矿物能源的消耗,杜绝了温室气体、污染物的直接排放,具有显著的节能环保效果和经济效益。
Carbon dioxide air source heat pump is an energy-saving and environmentally friendly refrigeration and heating technology established based on the principle of reverse Carnot cycle with CO_(2) as the refrigerant.The system uses the compressor to do work,obtains low-grade heat energy from the natural air,and provides a highgrade heat energy that can be used by people.Because CO_(2) heat pump has changed the traditional coal-fired and oil-fired heating mode,the utilization rate of electric energy is higher.Therefore,compared with conventional heat pump,in addition to the more environmentally friendly refrigeration working medium,CO_(2) heat pump can produce high-temperature hot water,which is better than ordinary air.The energy heat pump has a wide range of applications and can work at a lower ambient temperature,which expands the application field of the heat pump;it has nothing to do with the local geological conditions,reduces the construction risk and construction period,and expands the application scope of the heat pump.It makes full use of the energy of renewable resources-air,and replaces the existing traditional heating methods such as coal-fired,gas-fired,oil-fired or electric boilers.It reduces the consumption of fossil energy,eliminates the direct emission of greenhouse gases and pollutants,and has significant energy saving and environmental protection effects and economic benefits.In particular,it is of great significance to our country's industry and heating,and its application potential is very huge,and its development prospects are very considerable.
