摘要
为研究冷凝温度和热回收率、制冷能力之间的变化关系,结合试验数据对热回收系统进行理论分析,得出热水进水温度和冷却水流量的变化将对热回收空调系统的热回收率和制冷能力产生一定的影响。同时总结得出采用制冷剂R22的热回收系统热水箱的最佳设定温度为55℃。为今后热回收机组的设计提供了理论和试验依据。
In order to research the changing relation of heat recovery efficiency and re- frigerating capacity with condensing temperature, the heat recovery system is analyzed the- oretically according to experimental data. It is concluded that changes of hot water inlet temperature and flow rate of cooling water have impacts on the heat recovery efficiency and refrigerating capacity of heat-recovery air-conditioning system. It＇s also concluded that the optimum setting temperature of heat recovery system using R22 as refrigerant is 55 ℃. The theo- retical and experimental bases are provided for future design of heat recovery unit.
