Solar Energy And Cooling Dehumidification Technology Pan-Chen, Chan PE, FuLe M.E.M. Co., Ltd. Abstract The application of solar energy in Taiwan has been focused on solar water heater. However, since Taiwan is located in the subtropical region and surrounded by Ocean, there is less solar heat demand for heating water, especially in summer. In Fact, the unique climate and high relative humidity temperature character in Taiwan has resulted in much higher energy demand for cooling and dehumidification rather than heating. Electricity consumption for cooling demand is almost 50% or more. Absorption cooling is the popular system that applied with solar heat. Several lithium-bromide absorption chillers with solar thermal system are operated now in Europe and Japan. However, difficult operation, maintenance and high cost have moved back the more extensive application of the solar absorption cooling system. Nowadays, the new technologies on desiccant cooling, desiccant dehumidification, adsorption chillers and also thermo-acoustic refrigeration system have been introduced, which will bring better application for solar thermal. In the following article, each cooling and dehumidification technology will be discussed respectively, we look forward to see the widespread application of the solar thermal in the future, The increase in popularity of the solar thermal as alternative energy will reduce fossil fuel consumption, CO2 emission, and helps to relieve the increasingly worsen situation of the global warming.
