Heat pump

Desalination with humidification and dehumidification process is deemed as an efficient and promising means of utilizing the condenser and evaporator of heat pump to produce freshwater from seawater. This paper presents a new type desalination unit driven by mechanical vapor compression pump which w

This paper describes a novel system of solar assisted heat pump desalination. A single effect desalination unit has been designed and fabricated, and it is connected to an existing solar assisted heat pump. The system consists of a compressor, condenser, evaporator, solar evaporator-collector, desal

The paper, “Heat pumps as a source of heat energy for desalination of seawater”, was published in Desalination [Vol. 139, 2001]. In the paper, heat pumps using agent R12 or water and vapor were introduced to be used as a source of heat energy for desalination. The cyclic processes of heat pump were

Thermal desalination plants consume large quantities of heat energy for seawater evaporation. In condensing water vapor procured in evaporators and cooling distillate, a major part of heat energy is lost in the environment. Heat energy in processes of condensation and evaporation in desalination of

The multi-effect distillation (MED) process is the oldest process in desalination. References and patents have existed since 1840, more than 150 years ago. Vertical tubes, horizontal tubes and different types of submerged tubes have been commercialized and were used until 1960 when multi- stage flas
