The effect of insufficient refrigerant charge on the chiller: 1. If the suction pressure and discharge pressure of the compressor are lower than the normal value, then you need to check to see if it is due to insufficient refrigerant charge.
2. In the case of insufficient refrigerant charge, the compressor will run without a rated load, resulting in a light load or even idling of the chiller. At this time, the current is lower than the rated current. 3. Insufficient refrigerant charge of the ice water machine will also reduce the amount of evaporation in the evaporator, so that the cooling capacity will cause the cooling effect of the unit to be poor, and the room temperature or storage temperature will decrease slowly or not.
4. If the thermal expansion valve of the chiller is seen to be frost-free and rarely frost. There is no condensation, little or no condensate in the air conditioner, or the refrigerant may be undercharged. 5. If the evaporator of the freezer is rarely frosted, no frost, or no dew during air conditioning
