Cooling system with enhanced low ambient application for low boiling refrigerant

A cooling system comprising:

• a computer air conditioning (CRAC) unit;
• a refrigerant pump coupled to the CRAC unit, wherein the refrigerant pump is configured to provide a refrigerant liquid to the CRAC unit;
• a condenser coupled to the CRAC unit, wherein the condenser is configured to cool the refrigerant liquid provided;
• and
• one or more controllers communicatively coupled to the CRAC unit and the refrigerant pump, wherein the one or more controllers include one or more processors including a set of program instructions configured to cause the one or more processors to:
• receive outdoor temperature data from a temperature sensor;
• receive a predetermined outdoor temperature threshold;
• determine whether the outdoor temperature data received exceeds the predetermined outdoor temperature threshold received by comparing the outdoor temperature data received to the predetermined outdoor temperature threshold received, wherein the outdoor temperature data received exceeds the predetermined outdoor temperature threshold received when the outdoor temperature data received is at least one of less than or equal to the predetermined outdoor temperature threshold received;
• upon determining the outdoor temperature data received does not exceed the predetermined outdoor temperature threshold received, generate one or more control signals configured to cause a compressor of the CRAC unit to be idled;
• and
• generate one or more control signals configured to cause the refrigerant pump to be activated.
