8-72 Explain the reasons for high condensing temperature and how to deal with it?
Explains reasons for high condensing temp, including insufficient cooling, air in the system, excess refrigerant, and more, and provides solutions.
تفاصيل القضية
Answer: (1) The cooling water (air) volume is insufficient and the water (air) temperature rises. In this case, check whether the pipeline is blocked, whether the valve is opened normally, whether the water pump is running normally, whether the water pressure is normal, etc. (2) There is air in the refrigeration system and the air should be removed. (3) There is too much refrigerant in the system and the excess refrigerant must be released. (4) The condenser outlet valve is not fully opened, causing the condensing pressure to rise. (5) The condenser has been used for a long time and the dirt on the heat transfer surface seriously affects the heat transfer, causing the condensing pressure to rise. The surface dirt should be removed in time. (6) The thermal expansion valve is not working properly, resulting in an increase in condensing pressure. (7) The compressor exhaust temperature rises, causing the condensing temperature and pressure to rise. The machine should be shut down quickly.
