| 摘 要： | 热泵作为一种节能环保技术受到了世界各国的普遍重视,而空气源热泵可从大气中吸取丰富的低位能量,使用安装方便,运转费用较低,因此得以广泛推广应用。但是,普通空气源热泵的应用范围受到气候条件的约束,随着大气温度的降低,普通空气源热泵的制热量逐渐减少,不能满足用户对制热量的需求。当室外气温很低时,随着压缩机压缩比的不断增加,其COP急剧下降,排气温度迅速升高,从而导致压缩机不能正常运行甚至损坏。由于喷气增焓技术和高效过冷却等技术的应用,使得低温型空气源热泵得以在-15～-25℃的环境温度下应用,也使得空气源热泵在寒冷地区水稻芽种生产系统中的应用成为现实。

| Abstract: | Heat pump has been regarded widely as a kind of energy-saving technique,and it can extract abundant second-class energy from ambience.Because of its convenience and economization,air-source heat pump is most expersively adopted in heat pumps.However,its usage is limited by ambience.With the decrease of outdoor temperature,the heat that is required increases.When outdoor temperature is low enough,the heat of air-source cannot satisfy the request.And with the increase of pressure rate of compressor,the heatin... |
