Abstract
The air conditioner should efficiently control both the sensible as well as latent heat load of building in order to provide necessary indoor thermal comfort. The conventional vapor compression system usually controls the latent load by the process of condensation of water vapor in which air is cooled below its dew point temperature and then reheated again up to the required supply conditions. The conditions where latent load is dominant these two processes i.e. over cooling and then reheating again will increase the consumption of electrical energy and emission of CO2 remarkably. This increases the temperature on earth further due to global warming. To avoid this wastage of primary energy and emission of harmful gases, desiccant based dehumidification and cooling system is a good alternative to the traditional air conditioning system which is cost effective as well as environment friendly. It can be driven by thermal energy which makes a good use of solar energy which is free as well as clean. In this paper, are view of desiccant based sustainable cooling technology has been presented. The present study is undertaken from variety of aspects including background and need of alternative cooling systems, concept of conventional and desiccant based thermal coolers, system configurations, operational modes, as well as current status of the desiccant based sustainable cooling technology. The review work indicated that the technology of desiccant based cooling has a great potential of providing human thermal comfort conditions in hot and humid climatic conditions at the expense of less primary resources of energy as compared to conventional cooling systems. Various types of desiccant cooling systems have also been introduced in this paper.
