Solar Powered Adsorption Refrigeration System

Solar power is an environment-friendly source of energy which is abundant in nature. It also has the potential of reducing the world’s demand for fossil fuels. It is particularly attractive for use in adsorption refrigeration systems in areas of the world where electrical power is scarce and where there is a plentiful source of solar energy. Since there are few/no moving parts, the consumption of any mechanical energy is minimized. Such refrigeration systems function on the basis of adsorption and desorption which are the accumulation and release of gases (adsorbate) into a solid substance (adsorbent), respectively. Solar powered adsorption refrigeration systems (SPARS) have the advantage of being thermally-driven as well as the ability of operating with low-grade heat energy. In such systems, the compressor of a conventional refrigeration system is replaced by an adsorber. Moreover, SPARS are promising solar refrigeration method and have low maintenance and operating expenses. This paper focuses on the possibility of using the solar adsorption refrigeration technology for air-conditioning purposes in the UAE.
