Heat pump dedicated pressure regulating valve for direct heat pump advantages: 1, quickly adjust the equilibrium pressure between refrigerant system and waterway 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, heat pump pressure control valve for a stable total of heat pump condenser cold water, reverse flow of water and refrigerant in the case, the condenser wall of the refrigerant inside the tube wall and the external Water from top to bottom according to the temperature of non-polar layering, the refrigerant from top to bottom temperature is from high to low, water from bottom to top temperature is from low to high, water temperature in the process of rising, Not the same ----- in the lower part of the absorption of liquid refrigerant heat, the central absorption of refrigerant heat of liquefaction, the upper absorption of electricity and mechanical conversion to the refrigerant gas heat, because the refrigerant system condensation pressure is the liquefaction temperature, and the temperature in the condensation Medium temperature zone, so refrigerant system condensing 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 18--25kg / cm2, when the regulator valve detects the condensing pressure equal to the pressure set by itself ( 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, pressure resistance of the refrigerant side to 50kg / cm2 water side pressure capacity to 10kg / cm2 heat pump refrigerant system 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 directly control the water temperature, so that control more convenient. At the same time the outlet temperature can be controlled within plus or minus 0.5 degrees, electric series control valve in addition to all the advantages of manual control valve, it is part of the regulator valve installation electric adjustment device, and connected to the control panel, when the control panel settings A water temperature, the electric control device will be based on their own monitoring point temperature adjustment until the outlet temperature and the set temperature match, so you can avoid the water pressure changes or seasonal changes caused by the shortcomings of the error of the water temperature.
