23. iable operation at low ambient temperature is achieved with a pumpdown cycle a crankcase heater and a head pressure control valve As the ambient temperature falls and the head pressure decreases the valve maintains a minimum head pressure of 180 psi by bypassing discharge gas around the condenser to the receiver to increase the pressure at the condenser outlet This backs liquid refrigerant up in the condenser to reduce the area available for condensing which increases the head pressure to maintain the 180 psi set point A check valve is installed in the liquid line between the receiver and the condenser to prevent liquid migration from the receiver to the condenser during the off cycle The crankcase heater works in conjunction with a continuous pumpdown cycle to prevent accumulation of liquid refrigerant in the compressor oil during the off cycle This prevents compressor damage due to a flooded compressor start The low pressure control will start the condensing unit anytime the low side pressure rises above the 30 psi set point and pump the refrigerant out until the pressure falls to 10 psi The crankcase heater which is energized whenever the condensing unit has power keeps the compressor oil warmer than the coldest location in the system This minimizes off cycle refrigerant migration If power to the condensing unit is interrupted after the system is charged the compressor should not be started unless the crankcase heater has been energized for at lea
