摘要： The present disclosure relates to a heating ventilation and air conditioning (HVAC) system. The system includes a primary heat transfer loop configured to be disposed at least partially outside of a building, and the primary heat transfer loop includes a heat exchanger, a compressor configured to compress a refrigerant, where the refrigerant is reactive, a condenser configured to receive and condense the refrigerant, and an expansion device configured to reduce a temperature of the refrigerant. The system further includes a secondary heat transfer loop configured to circulate a two-phase fluid at least partially inside the building, wherein the two-phase fluid is less reactive than the refrigerant. The secondary heat transfer loop includes the heat exchanger, where the heat exchanger is configured to transfer energy from the two-phase fluid circulating in the secondary heat transfer loop to the refrigerant, and an evaporator configured to evaporate the two-phase fluid by exchanging energy with an air supply stream flowing across the evaporator.

摘要： A turbo-compression cooling system includes a power cycle and a cooling cycle coupled one to the other. The power cycle implements a waste heat waste heat exchanger configured to evaporate a first working fluid and a turbine configured to receive the evaporated working fluid. The turbine is configured to rotate as the first working fluid expands to a lower pressure. A condenser condenses the first working fluid to a saturated liquid and a pump pumps the saturated liquid to the waste heat waste heat exchanger. The cooling cycle implements a compressor increasing the pressure of a second working fluid, a condenser condensing the second working fluid to a saturated liquid upon exiting the compressor, an expansion valve expanding the second working fluid to a lower pressure, and an evaporator rejecting heat from a circulating fluid to the second working fluid, thereby cooling the circulating fluid.
