- product introduction:When the refrigerating device is running, if the condensing pressure is on the high side, the exhaust temperature of the compressor will rise, the compression ratio will increase, the refrigerating capacity will decrease, and the power consumption will increase. The higher the condensation pressure is, the greater the adverse effect is. The high condensation pressure is mainly seen in summer, when the condensation pressure should be reduced as far as possible to ensure the economy and reliability of the machine operation. Winter operation, condensation pressure may be too low, and will bring trouble to the work of the thermal expansion valve: valve before and after the pressure difference is too small, insufficient power for the liquid, so that the thermal expansion valve capacity decreased a lot; The liquid in front of the valve is easy to be gasified, which also seriously affects the flow capacity of the thermal expansion valve. It is easy to cause the evaporator lack of liquid, the unit refrigerating capacity dropped significantly. When the refrigerating device is running, only the condensing pressure is allowed to fluctuate in a reasonable range. Therefore, the condensation pressure must be adjusted. It is necessary to adjust the condensing pressure for the refrigerating equipment running all year round.The role of condensation pressure control valve condensation pressure control valve is in the operation of the refrigeration system, the condensation pressure to maintain a normal range. If the condensing pressure is too high, the refrigerating equipment will be damaged and the power consumption will increase, if the condensing pressure is too low, the refrigerant will be liquefied and the expansion valve will work, make the refrigeration system can not work normally, resulting in a substantial decrease in the refrigerating capacity. Condensing pressure control valve is usually installed in the condenser cooling water line (usually installed in the condenser inlet end) , according to the change of condensing pressure to regulate the flow of cooling water. It adjusts the valve opening by directly sensing the pressure change in the refrigerant cycle to allow enough cooling water to flow through, which saves a lot of cooling water. Simply put, it’s cooling on demand. When the condensing pressure of the compressor increases (i. e. the condensing pressure increases) , the valve will automatically open up, so that more cooling water into the condenser, accelerating the rate of refrigerant condensation; conversely, when the condensing pressure drops, the valve will automatically close small, so that the amount of cooling water into the condenser to reduce, so that the condensation pressure to maintain a certain range.
