Abstract
A refrigeration system comprises a compressor, a condenser, a receiver tank, an evaporator and a heat exchanger. The heat exchanger comprises an inlet positioned downstream of the receiver tank and an inlet positioned downstream of the compressor. The heat exchanger is configured to transfer heat between refrigerant received from the compressor and refrigerant received from the receiver tank, wherein a transfer of heat causes at least a portion of the refrigerant received from the receiver tank to transition from liquid to vapor. This process propels the head pressure of the compressor to increase to compensate for low ambient conditions. The heat exchanger comprises a first outlet in fluid communication with the first inlet, the first outlet configured to dispense the vapor refrigerant toward the receiver tank, and a second outlet in fluid communication with the second inlet and configured to dispense the refrigerant received from the compressor toward the condenser.
