Refrigerant gas in condenser 9 by total condensation after, by gas pipeline 7, reduce pressure by expansion valve 3, in evaporimeter 4, evaporate, the heat absorption after get back in the compressor 1.
Because after circulation, water in the water tank 5 and high temperature refrigerant gas carry out heat exchange, water temperature just raises gradually.Because refrigerant gas also contacts with high-temperature water, its temperature also raises along with the rising of water temperature.
But the temperature of cold-producing medium rises to a certain degree will be saturated, and at this moment heat pump just can't carry out operate as normal.Therefore, only depend on common water-cooled condenser 2 inoperable shortcomings, carry out heat exchange again, so just can guarantee the operate as normal of heat pump by refrigerant gas being sent into water-cooled condenser 9 and water in order to overcome.
The ratio of condenser 9 and 2 gas pipeline sectional area is 50% when following, on the one hand refrigerant gas by total condensation, with hydrothermal exchange efficient height; On the other hand because by flowing in the gas pipeline of the little condenser 9 of gas pipeline sectional area ratio condenser 2, the intermiscibility of refrigerant gas and oil also makes moderate progress.Therefore even adopt the HFC series refrigerant gas that does not have chlorine in the molecular structure, but also operate as normal of heat pump.
As shown in Figure 3, condenser 9 and 2 also can be designed to integrated (presumptuously being arranged).The profile of the water-cooled condenser of setting up 9 as shown in Figure 4, one of 10 li of cylindrical duct configuration with helical coil around flue 12, the outlet at its two ends is stretched out from pipe 10.Water inlet/delivery port 11 is installed on cylindrical duct 10, the back shaft 14 that is used for fixing plate 13 is installed in the enclosure interior center in addition, also can reach same purpose according to this incorporate design.
