1. PACKAGE BOCK CONDENSING UNIT temperature is too low (condensing temperature: refers to the condensation temperature of the refrigerant in the condenser) elimination method:
① Heat but lack of water: the high-temperature gas discharged from the compressor must not be accurately cooled, which will increase the condensation temperature, and sufficient water should be added.
②Heat but water temperature is too high: The high temperature gas discharged from the compressor must not be very badly exchanged, which will increase the condensing temperature, so appropriate cooling measures should be taken for cold but water.
③The refrigeration system is really high in emptiness and dryness, which increases the condensing temperature. The solution: the real emptiness of the system should be increased.
2. The PACKAGE BOCK CONDENSING UNIT temperature is too low:
①The amount of refrigerant in the system is insufficient: sufficient refrigerant should be added according to the instructions.
②Heat but the water temperature is too high or the water flow is too large: it should be adjusted appropriately according to the cooling capacity and the temperature difference.
3. PACKAGE BOCK CONDENSING UNIT has a lot of scale:
The important thing to form the scale in the PACKAGE BOCK CONDENSING UNIT is that the remaining amount of Ca, Ma, Na bicarbonate, sulfate and chloride, silica and other impurities in the cooling water, the existence of these substances makes the water It has a certain degree of hardness. After the formation of scale, the water flow resistance increases and the heat exchange efficiency decreases, resulting in an increase in the temperature of the PACKAGE BOCK CONDENSING UNIT, a decrease in the cooling capacity, and an increase in energy consumption. When it is slight, the pipe wall will be eroded.
In order to prevent such accidents, disinfected water should be used. If the water quality absolutely does not meet the requirements, chemical water treatment should be used. If the cooling water is seawater, measures should be taken in the design to prevent seawater from corroding pipelines and equipment, and adhesion or blockage of aquatic organisms and plants in the seawater to pipelines and equipment.
