Water pressure detection of 2 unit inlet and outlet pipes
Through the detection of the return water pressure and the water pressure value, and after the unit current judgment, the water flow rate of the refrigerator under the pressure difference between the inlet and outlet water is checked in the inspection book, and the flow rate of the machine is checked by consulting the specification. The table or the graph, thus the inhalation is judged whether the system is normal by the water flow in the broken water; and the difference between the water and the water is determined by which part of the water pipe has a large resistance value, corresponding scheme and action.
3 compressor copper tube suction temperature detection (only detected during cooling operation)
If in the cold water in the steamer's suction pipe machine to measure the flow to the compression channel is still evaporating heat, it will cause the compressor suction temperature is lower than 0 degrees; in addition, it is necessary to exclude the water temperature to set the compressor to inhale at 0 Degree, that is, the unit is driven to Ang Ming 30 random minute temperature low heat exchange water side line to transport the breaker is not enough to cause the evaporation temperature and evaporation pressure to fall, and lead to low fluoride and pressure caused by the decline; temperature standard The value needs to evaporate the low water temperature unit as long as the water flow compressor has a 6-8 °C suction overheating is normal. Under the normal water volume, the compressor point can be recognized that the steaming degree of the temperature is generally 0 °C, and the low system asks for the water problem.
4 pump running current detection
Through the machine water pump, and the water of the rated current detection group, the current pump rated rectification water flow rate and the current flow rate are determined as the non-force and the large water return system is small, and the previous parameters are broken together to obtain a Indeed comprehensive judgment detection analysis report
