Cooling device with subcooling system

A method of subcooling a refrigerant in a cooling device having a closed loop cooling cycle, the method comprising:

• connecting a heat exchanger to a condensed liquid refrigerant portion of the closed loop cooling cycle;
• providing a fluid from a fluid source in thermal communication with the heat exchanger;
• directing the refrigerant to the heat exchanger to cool the refrigerant and warm the fluid when a first temperature of the refrigerant is greater than a second temperature of the fluid;
• bypassing the refrigerant away from the heat exchanger when the first temperature of the refrigerant is less than the second temperature of the fluid;
• and
• routing the fluid from the heat exchanger to a fluid receiving device.

A cooling system having a subcooling device, the cooling system having a refrigerant in a closed loop refrigeration cycle, comprising:

• a heat exchanger having a refrigerant inlet configured to receive the refrigerant from the closed loop refrigeration cycle and a refrigerant outlet configured to return the refrigerant in a cooled state to the closed loop refrigeration cycle;
• the heat exchanger further including a fluid inlet configured to receive a fluid from a fluid source and a fluid outlet configured to discharge the fluid in a warmed state to a warm fluid usage application;
• and
• a control system operable to direct the refrigerant through the heat exchanger when a refrigerant temperature at the refrigerant inlet is greater than a fluid temperature at the fluid inlet and to bypass the refrigerant around the heat exchanger when the refrigerant temperature is less than the fluid temperature.
