How to determine refrigeration system lack of refrigerant

Time:2018-04-07 21:26:16 

Globaldemand for water heating(air to water heaters)Chinesesolution,the achievements ofsome enterprisestovacuum heat collectingtechnology,heat pump technology,refrigerationtechnology,system heattechnology,intelligent control technologyand other eighttrunkTechnology Groupas the core of theorganization structureand development pattern.In a refrigeration system,evaporator,condenser,compressorand a throttle valveisessential infourlargerefrigeration system,refrigerantrefrigeration systemdeficiencyjudgmentmethod and causeanalysis are as follows.

Lack of refrigerantin the evaporator,evaporationdecreased,so therefrigerating capacitydrop,the refrigeration effect is not good.

Thermal expansion valveor rarelyfrostingfrosting.In theair condition,no condensation,condensation waterwith little or no.

Due tolack of refrigerant,the suction pressure of the compressorand an exhaustpressurevalues lower than normal.

Due tolack of refrigerant,often make thecompressor withoutthe ratedloadoperation underlight load,the unitoridling,thecurrent is less thanrated current.
