Refrigerant shortage processing method

Insufficient refrigerant treatment method:

1. When the water temperature is 5 ° C In the above case, when the pressure of the low pressure gauge is less than 2 kgf/cm2, it means that the refrigerant is insufficient. First, the place where the refrigerant is leaked is subjected to trapping treatment, and then the dry filter is replaced and the vacuum is refilled to fill the appropriate refrigerant.

2. When it is found that the leakage refrigerant is partially immersed in water, stop the operation of the freezer immediately, and quickly remove the water from the water tank. Inform the company to dispatch personnel to handle the repair as soon as possible to prevent the compressor from inhaling water into the system and causing more serious damage.

Is the high and low pressure normal?

When the water-cooled compressor is in normal operation, the high pressure indicates that 12.5~15kgf/cm2 is the best, (air-cooled 14～17kgf/cm2 is the best) but not higher than 19.5kf/cm2, when the water-cooled pressure is higher than 19.5kgf/ Cm2, when the air-cooled pressure is higher than 24kgf/cm2, the high-voltage switch trip should be handled according to Note (1). The low pressure is 3.1~4.5kgf/cm2, but not less than 2kgf/cm2, less than 2kgf/cm2. Low-pressure tripping should be handled in accordance with Note (2).

When the pressure difference between the high pressure and the low pressure is very little or equal when the compressor is running, it means that the valve of the compressor itself is broken and broken. Please stop the operation immediately and inform the company to send someone to handle it. Please note that the above situation is normal when the compressor is running, if the high and low pressure balance is not running.
