Refrigerant-switching total-heat-recovery water-to-water screw-type heat pump unit

Abstract

本实用新型公开了一种冷媒切换全热回收型水-水螺杆式热泵机组,所述压缩机的出口端连接第一四通换向阀的高压入口端;所述第一四通换向阀的左、右接口端分别与第一冷凝/蒸发器的一端及第二四通换向阀的高压入口端连接,所述第一四通换向阀的中间出口端通过第一单向阀与压缩机的入口端连接;所述第二四通换向阀的左、右接口端分别与第二冷凝/蒸发器的一端及热回收器的入口端连接,所述第二四通换向阀的中间出口端通过第二单向阀与压缩机的入口端连接;所述热回收器的出口端分别通过第四单向阀及第五单向阀与第一冷凝/蒸发器和第二冷凝/蒸发器的另一端连接;所述第一电磁阀与第四单向阀并联连接,所述第二电磁阀与第五单向阀并联连接。
The utility model discloses a refrigerant-switching total-heat-recovery water-to-water screw-type heat pump unit. The exit end of a compressor is connected with a high-pressure entry end of a first four-way reversing valve; a left joint end and a right joint end of the first four-way reversing valve are connected with one end of a first condensing/evaporating device and a high-pressure entry end of a second four-way reversing valve respectively; an exit end in the middle of the first four-way reversing valve is connected with the entry end of the compressor through a first one-way valve; a left joint end and a right joint end of the second four-way reversing valve are connected with one end of a second condensing/evaporating device and the entry end of a heat recovery device respectively; an exit end in the middle of a second four-way reversing valve is connected with the entry end of the compressor through a second one-way valve; an exit end of the heat recovery device is connected with the other ends of the first condensing/evaporating device and the second condensing/evaporating device through a fourth one-way valve and a fifth one-way valve; a first electromagnetic valve is connected in parallel with the fourth one-way valve; and a second electromagnetic valve is connected in parallel with the fifth single-way valve.
