Heat pump dedicated pressure regulating valve is used to direct thermal heat pump advantages: 1, quickly adjust the pressure balance between the refrigerant system and the water system. Pressure control valve for heat pump through its own proportional computing function in a few seconds to find the balance of pressure and refrigerant pressure, refrigerant system to stabilize the high and low pressure corresponding position. And then to ensure that the water temperature is stable. 2, can effectively reduce the refrigerant system condensing pressure, protect the compressor, Dedicated heat pump pressure regulator can be a total of stable to the heat pump condenser cold water, reverse flow of water and refrigerant in the case of the condenser wall of the tube wall and the water outside the tube from top to bottom temperature according to the polar layer, the refrigerant from From top to bottom temperature is from high to low, water from bottom to top temperature is from low to high, the water temperature in the process of rising, in different sections of the absorption side of the refrigerant is not the same type of heat - in the lower absorption of liquid refrigerant heat , The central absorption of refrigerant liquefaction heat, the upper absorption of electricity and mechanical heat transfer to the refrigerant gas heat, because the refrigerant system condensation pressure is the liquefaction temperature, and the temperature in the condenser in the temperature region, so the refrigerant system condensation pressure will not be too high . 3, can increase the heat pump water temperature. Because the heat pump water absorption and mechanical conversion to the refrigerant gas heat, the temperature even up to Baidu, it will not exceed the scope of the compressor, so the system design is better, the water can be increased by about 20 degrees 4, can improve heat pump energy efficiency. Because the water outside the condenser wall and the wall of the refrigerant from top to bottom temperature by stepless layered heat absorption, so that the refrigerant flowing out of the condenser is extremely undercooled state, which means that the refrigerant side of the high heat almost all Absorbed by water. Thereby enhancing the heat pump energy efficiency ratio 5, the heat pump boot within a minute can have a preset stable hot water output. Generally in the heat pump compressor work 20-30 seconds (depending on the structure of the condenser), the heat pump refrigerant system condensing pressure will rise to 18--25kg / cm2, when the regulator valve detects the condensing pressure equal to its own set pressure 15--23kg / cm2), the water side corresponds to open the condensing pressure to stop rising, the preset stable hot water will be output 6, the main adjustment process is done by mechanical parts, and the moving parts are frictionless operation, so the product There is a long service life, and will not be affected by humidity and temperature Heat pump special pressure regulating valve in the regulation process is imported special steel to do axial telescopic movement, the centering and sealing are by foreign original rubber membrane deformation Complete without any friction. So even after tens of thousands of cycles the product will not affect the excellent performance. 7, the use of imported pressure parts, refrigerant side pressure capacity up to 50kg / cm2 water side pressure capacity to 10kg / cm2 Heat pump refrigerant system working pressure is generally 15 - 30kg / cm2, tap water pressure of 1-6kg / cm2, so do not have to worry about in adverse conditions will hurt the control valve or refrigerant leakage 8, electric series control valve panel can directly control the water temperature, so that control more convenient. At the same time be able to control the water temperature within plus or minus 0.5 degrees, In addition to all the advantages of electric control valve with manual control valve, it is part of the control valve regulator installed electric adjustment device, and connected to the control panel, when the control panel to set a water temperature, the electric control device will monitor according to their own The temperature of the water outlet is adjusted until the temperature of the water outlet matches the set temperature so as to avoid the disadvantage that the water temperature error is large due to the pressure change of the water supply or the seasonal change.
