A combined cooling, heating, and power system, including a working fluid cycling between a compressor and a turbine in combination with a power generator. A humidifying regenerator is disposed between the compressor and the turbine, and in combination with the working fluid upstream and again downstream of the turbine to humidify and then dehumidify the working fluid. A working fluid heat exchanger is in combination with the working fluid between the turbine and the humidifying regenerator for further heat the working fluid. The heat exchanger is in combination with a heat source that heats both the working fluid and provides a separate heating medium. A cooling device is in combination with the working fluid between the humidifying regenerator and the compressor, wherein the cooling device cools the working fluid before entering the compressor and provides a separate cooling medium.

Aspects of the present disclosure include a system for turbo-compression cooling. The system may be aboard a marine vessel. The system includes a power cycle and a cooling cycle. The power cycle includes a first working fluid, a waste heat boiler configured to evaporate the working fluid, a turbine, and a condenser. The condenser condenses the working fluid to a saturated or subcooled liquid. The cooling cycle includes a second working fluid, a first compressor configured to increase the pressure of the second working fluid, a condenser configured to condense the second working fluid to a saturated or subcooled liquid after exiting the first compressor, an expansion valve, and an evaporator. The turbine and first compressor are coupled one to the other. The waste heat boiler receives waste heat from engine jacket water and lubricating oil from a ship service generator. The evaporator cools water in a shipboard cooling loop.

The application relates to a binary cycle power system for generating electrical power. The system comprises a heat exchanger for evaporating a first fluid, a turbine converter, an electrical generator, and a first condenser for condensing the evaporated first fluid. The turbine converter converts energy of the evaporated first fluid to mechanical energy and the electrical generator generates the electrical power from the mechanical energy. The heat exchanger is a second condenser, which is a part of a heat pump that transfers heat from a second fluid circulating in the heat pump to the first fluid so that the first fluid evaporates.

The present disclosure provides pumped heat energy storage systems that can be used to store and extract electrical energy. A pumped heat energy storage system of the present disclosure can store energy by operating as a heat pump, whereby net work input can be used to transfer heat from the cold side to the hot side. A working fluid of the system is capable of efficient heat exchange with heat storage fluids on a hot side of the system and on a cold side of the system. The system can also extract energy by operating as a heat engine transferring heat from the hot side to the cold side, which can result in net work output.
