Compressor heat from the refrigerant compressor repair method for R22. Indoor temperature of 10 degrees, the outdoor ambient temperature of about 31 degrees, the compressor run time working pressure 3.1kgf / cm2 and 14.2kgf / cm2, low pressure shutdown is about 6.8kgf / cm2, the compressor is running a three-phase current of 9.13 A / 9.35A / 9.52A, compressor surface temperatures over 100 degrees, after a period of time to protect the compressor is running, what is the reason? Obviously the lack of fluoride, low suction pressure Xuzhou used central air conditioning recovery, superheat great. When we judged that the system is blocking me from simple to complex in accordance with the recommendations, to reduce costs to deal with. A severe fouling system, we can choose to let go of the refrigerant, welded pipe group open hand air conditioning too cold, with high-pressure nitrogen gas were blowing dirt, put fluoride in time to pay attention, the best situation in the air conditioning and heating, quickly open crude copper cut-off valve cap, let refrigerant spray instantly, you can put the system out of the dirt. In too cold weld the tube group must pay attention to the one-way valve to cool. 2 carbon tetrachloride cleaning method: This method put the system into the dust, or refrigeration compressor oil when burned after a paste using carbon tetrachloride corrosive, volatile, they must be in the cleaning system The one-way valve, four-way valve, compressor welding, to avoid its corrosion. Can be used as a power vacuum on the system piping repeated cleaning, after cleaning, use a high-pressure nitrogen blow residue, carbon tetrachloride under nitrogen volatilization quick action to reduce the corrosion of the system. 3 plus dry filter method: After the success of both methods 1 and 2 need to add air conditioning back on dry pipe filter, allows the system in the water, refrigeration oil impurities, dirt filtered out. 4-way valve commutation law: when the system is often stuck in the capillaries usually blocking the front or the back, we instantly give way valve is energized, power to change the flow of the refrigerant, the dirt stuck in the capillary at the red open, so that the normal flow of the refrigerant to achieve the cooling and heating purposes. 5 welding baking method: When the system is blocked when the oil in the capillary condensation phenomenon Xuzhou Department has used air-conditioning parts, we are available at welding bake frosting to reduce the viscosity of the oil, allowing the system to normal operation. Gree air in heating mode boot, outside the machine is working properly. But open to the five minutes or so, the screen appears a symbol HI, this is how the same thing? Gree display H1, which is conditioned defrost. Because hot air conditioning system inside and outside the machine becomes loose cold. When the heat reaches a certain temperature, Xuzhou hand air conditioning repair, condenser outside the machine will defrost, within this time, fans stop outside the machine fan stop, compressor, four-way reversing valve, change back to the outside Mechanism of heat to dissipate outside cream machine (steam and water will be produced). Because different defrost time, so sometimes can not see the water. If your air conditioner more frequently, then defrost, Jinan Gree air-conditioning repair propose to wash the filter inside the machine, while the temperature can be adjusted to give a few high.
