MnCl2/CaCl2-NH3再吸附系统的制冷性能
Performance of MnCl2/CaCl2-NH3 resorption refrigeration system
摘要
Abstract
The solid composite sorbents based on the matrix of expanded natural graphite treated with sulfuric acid are developed,and a MnCl2/CaCl2-N H 3 resorption refrigeration system driven by low-grade thermal energy is established and experimentally investigated.Results indicate that 1 6 0 ℃ heat source temperature is the inflection temperature of coefficient of performance for refrigeration (COP),and a maximum cooling power of 2.9 8 kW is achieved.When the heating temperature is higher than 1 6 0 ℃ , sensible heat load of the system increases which means keeping heating high temperature salt (H TS)sorption bed will reduce the overall refrigeration efficiency.For refrigeration temperature of 1 5 ℃ ,COP of the system ranges from 0.2 8 4 to 0.3 9 6 while specific cooling power (SCP)ranges from 1 0 0.3 to 3 3 8.8 W · kg - 1.SCP increases with the increment of heat source temperature.关键词
