摘要
在恒温恒湿空调系统中,为了节能环保、减少再热过程中的能量损失,提出利用制冷系统的冷凝热用于再热来代替电加热的方式。本文以此为基础,利用仿真平台对采用不同再热方式的各系统进行了系统建模与理想循环分析。通过对仿真结果的定性分析,得到了使用冷凝热再热的方式比过冷再热方式范围较广,但系统性能系数较低。
In the constant temperature and humidity air condition system,the condenser heat is used to reheat supply air instead of electric heating in order to reduce the energy consumption of reheating air,to save energy and to protect environment.Based on this heat recovery theory,system models are set up based on the simulation platform,and different parts of condenser heat for supply air reheating are numerically compared.Some meaningful conclusions for actual system design are achieved:the working range of condensing heat is wider than that of subcooling heat,while its coefficient of system performance is lower than the latter.
