用于使用环境兼容的制冷剂的热泵
Abstract:
按照本发明的热泵包括内置的热交换器和调节装置，该调节装置设计用于使压缩机出口处的工作流体的温度处于在相同压力下在露点之上的能预设的最小间距处。借助这种对热泵过程的额外介入，可以在热泵中使用新的制冷剂，所述制冷剂在温熵图中具有低于1000(kgK2)/kJ的较小冷凝曲线斜率并且其突出特点在于很好的安全性和环保性。
Abstract(English):

A heat pump includes an internal heat exchanger and a regulating device designed to bring the temperature of the working fluid at the outlet of a compressor to a specifiable minimum difference above the dew point at the same pressure. This allows the use of novel coolants in heat pumps, e.g., coolants having a low dew line slope of under 1000/kJ in the temperature-entropy diagram and characterized by very good safety and environmental properties.
