Hisense central air conditioner, no cooling (heating), no pressure on the low pressure side
.Fault phenomenon
Central air conditioner The unit operates normally and does not cool. Check the refrigeration system pressure when the unit is turned on.
.Fault Analysis
Most of them are caused by the lack of refrigerant in the refrigeration system, and a few are caused by blocked capillary tubes and filters.
.Inspection
The first step is to observe the high-pressure and low-pressure stop valves and connecting pipes of the outdoor unit. If there is oil leakage, it means there may be a leak here. If the connection pipe is leaking, recycle the refrigerant to the outdoor unit before repairing it. If the high and low pressure stop valves are leaking, bleed the refrigeration system and replace the stop valves with the same specification.
The second step is to stop the machine and check whether the pressure gauge rebounds. If the pressure indication value rebounds, it means that the filter is dirty and blocks the refrigerant. Replace the filter or clean it.
The third step is to check the opening of the indoor unit connecting pipe. Open the bandage. If there is oil on the connecting pipe mouth, you should determine whether there is a leak. If the connecting pipe is lengthened, the welding joint of the extended pipe must be checked for leaks. If there is a leakage point, close the high and low shut-off valves of the outdoor unit and seal the leakage point.
The fourth step is to remove the outdoor unit casing and check the condenser and pipelines for oil stains. If there is oil stain somewhere, deflate the refrigeration system and then repair the leaking spot by welding.
The fifth step is to take time out.
The sixth step is to add the appropriate amount of refrigerant.
