The influence of the change of suction pressure on the refrigeration system
The influence of the change of suction pressure on the refrigeration system When the refrigeration system is running, its suction pressure has a close relationship with the condensing temperature and the circulating amount of refrigerant. For systems that use capillary tubes for throttling, the suction pressure is related to condensing pressure, refrigerant quantity, compressor efficiency, and cooling load. Therefore, when checking the refrigeration system, a pressure gauge should be installed in the suction pipe section. Reading the suction pressure provides an important basis for analyzing faults. Factors of low suction pressure. The suction pressure is lower than the normal value due to the following factors: small amount of refrigerant, small cooling load, low condensing pressure and poor filter flow. The above factors will reduce the circulation flow of the system, and the heat load of the condenser will be correspondingly reduced, so that the condensation pressure will drop. And ...
