Experimental Study on Transition Heat Adjustment of CaCl₂·6H₂O

Abstract:

Transition heat adjustment of CaCl₂·6H₂O added small quantity of stable additives (Ba (OH)₂ and SrCl₂·6H₂O) was investigated by means of adding excess water. The experimental investigation results showed that, the transition heat adjustment of CaCl₂·6H₂O could be realized by adding excess water. With regard to CaCl₂·6H₂O, the suitable adjustment range of transition heat was 170kJ/kg-191.2kJ/kg as the proportion of adding excess water was 0-12.5% by weight; during the suitable adjustment range of transition heat, the phase change material with a random transition heat could be prepared by adding suitable excess water according to the actual requirement, and the transition heat of CaCl₂·6H₂O with different proportion of excess water could be forecasted. It is very beneficial for temperature and heat control in greenhouse.
