Abstract
The results of tests of the laboratory prototype of adsorption chiller based on ecologically sound working pair "water - SWS-1L adsorbent" are presented. The adsorbent relates to the family of selective water sorbents and is a mesoporous silica gel KSK modified with calcium chloride. The device produces cold water at a temperature of 5-10 oC, which can be used in air conditioning systems, to store food, etc. High coefficient of performance reaching 0.6 for low temperature of water desorption (90-95 oC) was obtained during the test of the device. This allows the investigated adsorbent to become a real alternative for traditional materials (silica gel, zeolites) for use in ecologically pure adsorption systems involving low-potential heat ( T 100 oC) |
