The effect of changes in exhaust pressure (condensing pressure) on the system
The effect of changes in exhaust pressure (condensing pressure) on the system When the refrigeration system is running, the exhaust pressure corresponds to the condensation temperature, and the condensation temperature is related to the flow and temperature of its cooling medium, the amount of refrigerant injected, the efficiency of the compressor, and the amount of cooling load. When checking the refrigeration system, you can install an exhaust pressure gauge on the exhaust pipe when inspecting the refrigeration system to detect the exhaust pressure as a fault analysis data. Factors of high exhaust pressure. The exhaust pressure is higher than the normal value due to the following factors: low cooling medium flow rate or high cooling medium temperature, excessive refrigerant charge, heavy cooling load, etc. The above factors will increase the circulation of the system, and the condensing heat load will increase accordingly. In order to adjust the heat dissipation, the only way to incr...
