An indirect evaporative cooling system for cooling a space adjacent to or containing an ablution bay is described. The indirect evaporative cooling system includes a greywater source from the ablution bay and evaporative cooler apparatus located above the space to be cooled in a dome shaped housing. The evaporative cooler apparatus includes a wet channel, at least one spray nozzle, and a dry channel. The at least one spray nozzle is located at the top of the evaporative cooler apparatus and is fluidly connected to the greywater source and the wet channel. The wet channel is located directly above the dry channel. A first side of the dry channel is connected to a first opening with a fan and outside air.

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.

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.

The integrated solar absorption heat pump system includes an absorption heat pump assembly (AHPA) having a generator, a condenser in fluid communication with the generator, an evaporator/absorber in fluid communication with the condenser and the generator, and a heat exchanger in communicating relation with the evaporator/absorber; a solar collector in fluid communication with the generator of the AHPA; a photovoltaic thermal collector in communicating relation with the evaporator/absorber of the AHPA; a plurality of pumps configured for pumping a fluid throughout the system to provide the desired heating or cooling; a power storage source, e.g., a solar battery, in communicating relation with the photovoltaic thermal collector; and a coil unit in communicating relation to the evaporator/absorber for receiving an air-stream. The absorption heat pump assembly can include an absorber and a solution heat exchanger.
