摘要:
针对夏热冬冷地区对冬夏两季双高效供冷/供热空调设备的需求,提出了采用热源塔热泵达到夏季高效供冷而冬季高效供热效果的解决方法.对热源塔热泵的原理和工作过程及其与冷水机组和空气源热泵的异同点进行了分析,建立了叉流式热源塔装置,并在不同室外空气参数情况下,以水和溶液(乙二醇水溶液)作为介质且在不同液气比时,对热源塔换热性能进行了研究.实验结果表明:调节室外空气温度从5.5 ℃升高到18.5 ℃,分别运行乙二醇水溶液和水,热源塔液气比优化值基本保持在0.25~0.4,而热源塔作为冷却塔使用时液气比优化值为1.33~1.67左右.冷却塔/热源塔的液气比优化值在冬季时小于夏季,此结果将为热源塔的设计及其应用提供实验数据支撑.
Abstract:
For the demand of central air-conditioning equipment with high efficiency both in summer and in winter in hot summer and cold-winter zone, heat pump with heat-source tower is put forward to realize the high efficiency for heating and cooling. Its principle and working process, as well as the principle and working process of water-cooled chiller plant and air-source heat pump, were contrastively analyzed, and the cross-flow heat-source tower equipment was built. Under different outdoor air parameters, with water and solution (glycol solution) circulating in the cross-flow heat-source tower, the optimized liquid to gas ratio was studied. Experimental results show that the optimized ratio always remains at 0. 25 to 0. 4 when the outlet air temperature is regulated from 5. 5 ℃ to 18. 5 ℃ with the medium of water and glycol solution. While heat-source tower is used as cooling tower, the liquid to gas ratio keeps at 1. 33 to 1. 67. The liquid to gas ratio of heat-source/cooling tower in winter is lower than in summer, which provides a guidance for the optimized design of the heat-source tower.
