Abstract
Systems and methods for providing consistent and reliable movement of refrigerant within a cooling system for a data center are disclosed. By implementing fluid transfer valves such that a thermosyphon heat exchanger fill loop allows refrigerant to circulate between an isolated refrigerant storage space and a heat exchanger, the data center is cooled more efficiently.
Claims20
A system, comprising:
- a first heat exchanger;
- a second heat exchanger, comprising an evaporator side and a condenser side, and connected to the first heat exchanger;
- a compressor, connected to the second heat exchanger and to the first heat exchanger;
- an evaporator, connected to a condenser and to the first heat exchanger;
- the condenser;
- a pump configured to cause refrigerant to flow between the evaporator and the condenser side of the second heat exchanger;
- a first fluid transfer valve, located in between a first side of the condenser and the condenser side of the second heat exchanger;
- a second fluid transfer valve, located in between the condenser side of the second heat exchanger and a second side of the condenser;
- and
- a third fluid transfer valve, located in between the condenser side of the second heat exchanger and the pump.
