A cooling and desalination system includes a humidification-dehumidification (HDH) system and an ejector cooling cycle (ECC) system. The HDH system includes a heater for heating saline water, a humidifier for humidifying a carrier gas using the saline water, and a dehumidifier for dehumidifying the carrier gas to obtain desalinated water. The ECC system includes a generator for generating a primary flow of a refrigerant, an evaporator for cooling and providing a secondary flow of the refrigerant, an ejector for the primary flow and the secondary flow to pass through to obtain a super-heated stream, and a condenser. The heater and the generator are configured to connect to a heat source. The ECC system and the HDH system are connected at the condenser for heat exchange between the super-heated stream and the saline water to pre-heat the saline water.

Cooling and desalination system

A multimode system for cooling and desalination includes a humidification-dehumidification (HDH) system, an ejector cooling cycle (ECC) system and valves. The HDH system includes a heater, a humidifier and a dehumidifier. The ECC system includes a generator, an evaporator, an ejector and a condenser. The valves are configured to connect to inlets and outlets of the heater, the generator and a heat source so that by selectively opening and closing the valves, the heat source is connected to the heater while disconnected from the generator, or connected to the generator while disconnected from the heater, or connected to both the heater and the generator, or disconnected from both the heater and the generator. The ECC system and the HDH system are connected at the condenser for heat exchange.
