Special pressure pump control valve and direct heat pump (Photos) – heat pump in
Channel Recommended: Welcome to the "air can" hot water saving Miles
Installation diagram Pump Special pressure Control Valve Heat for direct heating Pump Advantages:
1, rapid cooling system and water system regulating the balance between the pressure.
Manual adjustment Valve (Left), automatic control valve (right)
Special pressure pump control valve operation through its own function with the ratio of pressure in seconds to find the balance point with the refrigerant pressure, refrigerant system to stabilize at the corresponding position of high and low pressure. Thereby ensuring the water temperature stable.
2, can effectively reduce the refrigerant condensing pressure, protection Compressor ,
Pump pressure regulating valve can be dedicated to the heat stability of Condenser Cold water, in water and reverse flow of refrigerant, the condenser wall and the refrigerant within the outside wall of water from top to bottom according to the temperature of polar layered, high to low temperature refrigerant from top to bottom, water from down to the temperature from low to high, the water temperature rising process, the refrigerant side of the heat absorption of different segment different types of —– in the lower part (region 3) absorption of liquid refrigerant heat, central (region 2) Absorption Refrigerant liquefaction heat, the upper (area 1) absorption of electrical and mechanical transformation of gaseous refrigerant to the heat, because the impact pressure refrigerant condensing temperature is liquefied, and then the temperature in the temperature region in the condenser, the refrigerant condensing pressure is not too high .
3, can increase the heat pump water temperature.
Because the water pump section (condenser region 1) absorption of electrical and mechanical transformation of gaseous refrigerant to the heat, the temperature even up on Baidu, the compressor will not have more than the specified scope, so in the case of good system design, effluent can be increased by 20 degrees
4, can improve the heat pump energy efficiency.
Because the condenser wall and the wall of water outside the house from top to bottom according to the temperature of the refrigerant absorbs heat non-polar layered, so that out of the condenser (region 3) of the refrigerant is extremely cold conditions, that is the refrigerant Almost all of the side of the high heat absorbed by water. To improve energy efficiency heat pump
5, pump start within one minute of hot water are preset and stable. Usually in the heat pump compressor
20? 30 seconds (depending on the condenser configuration), heat pump refrigerant condensing pressure will be risen 18–25kg/cm2, when the control valve to the condensation pressure is equal to their own perception set pressure (15–23kg/cm2), the water side of the corresponding opening, condensation pressure to stop rising, then preset the stability of the hot water output
6, the main adjustment process is completed by mechanical components, and the moving parts are friction-free operation, so the products have long service life, and is not affected by humidity and temperature
Dedicated pump pressure regulating valve in the adjustment process is to import special steel membrane axial stretching exercise to do, the aligning and sealing is by deformation of the foreign original rubber membrane to complete, without any friction. Therefore, even after tens of thousands of times the product cycle to work will not affect the excellent performance.
7, with parts imported pressure, the refrigerant-side pressure ability to move side to side 50kg/cm2 water pressure capabilities up to 10kg/cm2
Heat pump refrigerant system operating pressure is generally 15–30kg/cm2, water pressure 1-6kg/cm2, so do not have to worry about bad working conditions will be hurt in the control valve or refrigerant leak
8, panel electric series control valve can be directly controlled 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,
Electric series valve manual valve than with all the advantages, which is installed in the regulation of electric valve adjustment part of the adjustment device, and connect to control the board, when the operation panel to set a water temperature, the electric control device will be control points according to their water to adjust the temperature until the water temperature and the set temperature line, so avoid the season due to water pressure changes or changes in water temperature caused by the shortcomings of large errors
