Common practice of oil return design in refrigeration system

When the condenser is installed higher than the compressor, a U-shaped bend is required at the intake pipe of the condenser to prevent oil from returning to the exhaust side of the compressor during shutdown and also help prevent liquid refrigerant from the condenser

Common system failures of refrigeration equipment

Common system failures of refrigeration equipment 1. Liquid return: For refrigeration systems using expansion valves, liquid return is closely related to the selection and use of expansion valves. Expansion valve selection is too large, the superheat setting is too small, the installation method of the temperature sensor is incorrect, the insulation bandage is damaged, and the expansion valve failure may cause liquid return.<img src="{{media url=&quot;Common_system_failures_of_refrigeration_equipment2.png&quot;}}" alt="" />
