Since 2008, Mitsubishi Plastics, headquartered in Chuo-ku, Tokyo, Japan, has been manufacturing parts, such as heat exchangers, coated with AQSOA, a zeolitic water vapor adsorbent that is able to efficiently release water vapor, even at relatively low temperatures, the company says. Since heat exchangers coated with AQSOA are able to reduce the consumption of energy, the parts are already being used in adsorption chillers (cooling capacity of 9-350 kW) in Japan and Europe.
According to Mitsubishi Plastics, this compact adsorption chiller can be used for cooling data centers or houses through the use of hot water from solar water heaters and cogeneration systems. It can also utilize waste heat in small industrial facilities.
When combined with a solar water heater, the cooling performance of this product will surpass by 50 percent that of a traditional silica gel adsorption chiller, says the company. When the product is combined with a cogeneration system, the system is expected to reduce electricity consumption by up to 20 percent from that of coolers with compressors (based on Mitsubishi Plastics research).
