空调冷凝热回收热水供应系统计算机模拟分析

Computer simulation of air-conditioning heat recovery hot water supply system

分析了空调冷凝热回收热水供应系统HRHWS(HeatRecoveryHotWaterSupplySystem)模型与控制策略,针对香港某中高档旅馆,以常规燃煤、电锅炉热水供应系统和HRHWS辅助燃煤、电锅炉热水供应系统作为对比方案,进行计算机模拟,结果显示:HRHWS系统较常规系统分别节约能量 22%、56%;不同热源形式(除煤外)HRHWS系统可节约运行费用 70%以上;城市中心区各种污染物降低 99%左右,空调期内系统逐周热污染减排率接近 43%. 模拟结果验证了HRHWS系统是一种集节能、环保、降低运行费用等多项优良性能于一身的新型系统,具有较高的应用价值.

The model and control policy of air-conditioning heat recovery hot water supply system (HRHWS) is analyzed. Four system schemes are supposed to exist in HongKong luxury hotel, two of them are the traditional hot water supply system with the fuel of coal and electric energy, the other two are the HRHWS system with coal and electric energy to be the assistant fuel. Computer simulation results show, HRHWS systems may save 22%, 56% energy respectively by different heat source; cut down more than 70% operation charge; reduce 1% contaminators output compared to the traditional ones. Weekly heat contamination may decrease nearly 43%. Therefore, the HRHWS system has much more practical value due to its excellent property in energy saving, environment protection and low operation charge.
