How to adjust the capacity of refrigeration compressor

How to adjust the capacity of refrigeration compressor The capacity of the compressor is determined according to the maximum production of BOG in the storage tank. After the compressor is selected, its capacity is constant. If the amount of inhaled air is greater than the amount of BOG produced in the tank, the tank pressure will drop.
