使用热力膨胀阀的热泵机组,由于制冷和制热运转工况不同,故所需的热力膨胀阀的最佳开度不同。为了节约成本,避免使用两个热力膨胀阀,文章提出了一种新型的用于热泵的节流机构,实现了制冷和制热的最佳匹配。

The heat pump units used thermal expansion valve have two different operation conditions： the cooling operation condition and the heating operation condition, so the best required opening degree of the thermal expansion valve is different. In order to save costs and avoid using two thermal expansion valves, the paper proposed a new throttle mechanism used for the heat pump and realizes the best match of the cooling and heating.
