Definitions

  • the heat pump system also includes a reversing valve 50 disposed in the refrigerant circuit for inversion of the refrigerant cycle.
  • the reversing valve can be in form of a four-way valve placed after the compressor 10 and before the first or the second heat exchanger 20, 40.
  • the four-way valve 50 can be a solenoid operated valve. When the valve is deenergized, the system is in the heating mode, and the refrigerant passes through the four-way valve via a channel from the compressor 10 to the first heat exchanger 20. When the four-way valve is energized, the system works at the cooling mode, and inside of the four-way valve, the channel from the compressor 10 to the first heat exchanger 20 is switched to another channel from the compressor 10 to the second heat exchanger 40.
  • the temperature sensor 70 Since the temperature sensor 70 is so positioned that it detects the temperature of the refrigerant before entering the four-way valve, the influence of the reversing valve in determining the super-heating degree can be avoided, thereby assuring the refrigerant evaporation is completely done in the second heat exchanger and no refrigerant in liquid state is sucked into the compressor. Moreover, the system can work more efficiently, because a relatively lower target super-heating degree can be defined.
  • the minimum steady super-heating degree can be set at 4K in this case, compared with that (3K) of a normal heat pump system without a four-way valve, it may be a little bit higher, nevertheless, if compared with that (7K) of a traditional heat pump system with a four-way valve, the minimum steady super-heating degree become much lower. Furthermore, this relatively lower target super-heating degree makes the system to be easily reach and maintain it, which results in the superheating becomes more steady, and improving the performance of the compressor accordingly.
  • Fig.2 shows a second embodiment of the heat pump system, and the only difference with respect to the first embodiment is that the location of the pressure sensor is moved from the compressor suction side to the position between the second heat exchanger 40 and the reversing valve 50, preferably, the pressure sensor 62 is located in the outlet pipe of the second heat exchanger 40.
  • Fig.3 shows another alternative position of the pressure sensor, wherein, a pressure sensor 63 is positioned between the second heat exchanger 40 and the throttling device 30.
  • Fig.4 shows a fourth embodiment of the system, and the only change with respect to the third embodiment is that the pressure sensor is replaced with another temperature sensor 64 that is able to directly detect the saturated temperature at the low pressure side.
