一种空气源高温热泵
本技术涉及热泵领域,特别是涉及一种空气源高温热泵。
技术介绍
空气源高温热泵常用于为生产过程提供热水,具有安全、节能的优势。空气源高温热泵常用温熵图上饱和气相线斜率大于0的制冷剂作为工质。空气源高温热泵以这类制冷剂为工质时,压缩机排气过热度小,冷凝器(逆流式)中制冷剂和水最小温差点出现在冷凝器进出口。由于制冷剂是在等温条件下冷凝放热,导致冷凝器中制冷剂和水在除进出口外的其它部位均存在过大传热温差,有效能损失大,造成能源浪费。
技术实现思路
为减小传统空气源高温热泵因冷凝器中制冷剂和水的平均传热温差过大造成的能源浪费,本技术提供了一种设置有低温热水加热旁路的空气源高温热泵装置。本技术所采用的技术方案是:一种空气源高温热泵,它包括压缩机9、冷凝器6、膨胀阀4、蒸发器1,其特征在于:压缩机9出口设置有依次串联喷射器7、副冷凝器3和副膨胀阀2的旁路,冷凝器6和膨胀阀4间串联有冷却器5。所述喷射器7的高压蒸气进口与压缩机9出口相连,低压蒸气进口与蒸发器1出口相连并配置止回阀8,混合蒸气出口与副冷凝器3进口相连。所述副膨胀阀2的出口与蒸发器1进口相连。冷水并联通过 ...
