摘要： Systems and methods are provided for data center cooling by vaporizing fuel using data center waste heat. The systems include, for instance, an electricity-generating assembly, a liquid fuel storage, and a heat transfer system. The electricity-generating assembly generates electricity from a fuel vapor for supply to the data center. The liquid fuel storage is coupled to supply the fuel vapor, and the heat transfer system is associated with the data center and the liquid fuel storage. In an operational mode, the heat transfer system transfers the data center waste heat to the liquid fuel storage to facilitate vaporization of liquid fuel to produce the fuel vapor for supply to the electricity-generating assembly. The system may be implemented with the liquid fuel storage and heat transfer system being the primary fuel vapor source, or a back-up fuel vapor source.

摘要： A cooling system includes a main refrigerant circuit that includes a compressor, a heat rejection heat exchanger, one of an expander and an expansion device, at least one evaporator coupled to a thermal load, and a suction accumulator. A charge management circuit includes a charge management receiver configured in parallel with the compressor and the heat rejection heat exchanger. A controller is configured to accumulate and discharge reserve refrigerant to and from the charge management receiver to provide flexibility in system operation as refrigerant in the main refrigerant circuit operates in sub-critical, trans-critical, and super-critical modes of operation.

摘要： An apparatus and method for generating a vapor with a compact vaporizer design and exposing the gas and liquid mixture for vaporization to a reduced maximum temperature. A gas and liquid droplet flow through a metal housing configured to heat the gas and liquid droplet mixture flow for vaporization includes directing the gas and liquid droplet mixture through an inlet of the metal housing and flowing the gas through a tortious flow path defined by a plurality of tubular flow passageways arranged around a central axis for vaporization. The flow path is directed through a heat exchanger including one more changes in direction of flow path before flowing into the further tortious flow path described above. Residual liquid droplets may be further vaporized by flowing through a second metal housing configured to heat the gas and liquid droplet mixture for vaporization and having a similar construction to the first metal housing and providing a second tortious flow path.

摘要： A flow control device is used to regulate fluid flow from an upstream supply source to a downstream destination within a plant. At least portions of the flow control device are fabricated from one or more thermostatic materials selected based on the specific thermostatic properties thereof. The basic arrangement of the flow control device includes at least one housing with at least one thermostatic beam and at least one wall fixed thereto to define a void interior area with opposed open ends, and a center plug member with at least one opening in at least one wall thereof arranged within the interior area for temperature dependent fluid flow therethrough.
