What is the reason for the cold water outlet temperature difference of about 10 in the process of using industrial chiller

2021-07-22

Industrial water chiller in the process of use will always encounter a variety of trouble, the following collated some common problems for your reference;

1. What is the reason why the difference between high and low pressure is too low?

When the external temperature is very low, the temperature difference between the refrigerant water and the cooling water of the half-sealed screw is small, resulting in the pressure difference between the suction and the exhaust is small, and the problem of low high and low low pressure will occur.

2, low temperature chiller belongs to static equipment or dynamic equipment?

Equipment is divided into dynamic equipment, static equipment, dynamic equipment refers to the driving machine driven by the rotating equipment, such as pumps, compressors, fans, motors and molding machines, packaging machines, mixers and so on; Static equipment mainly refers to furnace, tower, reaction equipment, storage tank, heat transfer equipment, etc. Among them, the more special air cooler, air cooler needs to press the equipment management, air cooling bundle according to static equipment management. The chiller has pump, compressor, fan, motor and other components, so the chiller belongs to the dynamic equipment.

3, water-cooled screw chiller where to come out of chilled water and cooling water?

The one in the water tower is the condenser, and the water circulating there is the cooling water. Evaporator there out of frozen water, generally do insulation, and the evaporator is above the condenser, the evaporator is thicker than the condenser.

4. What is the reason for the difference between the evaporating temperature of the refrigerator and the cold water outlet temperature of about 10?

①, return temperature is too high (capillary or throttle problem)

②, the condenser heat dissipation effect is not good

③, the refrigerant amount in the refrigeration system is too little.
