Influence of heating regulation modes on performance of heat pump
摘要：
针对回收利用电厂汽轮机排汽余热的溴化锂吸收式热泵及其供热系统，通过VB编程进行热泵机组的热力计算，分析了不同集中供热调节方式对热泵机组性能和供热系统能耗的影响。结果表明：对于直接连接热水供热系统，在室外温度较低时质量-流量调节方式的热泵能耗最小，室外温度较高时分阶段改变流量质调节方式的热泵能耗最小。
Abstract：
For the lithium bromide-water absorption heat pump and its heating system which recovers the waste energy of exhausted turbine steam from the power plant, calculates the thermal parameters of heat pump units by VB program, and analyses the effect of regulation modes on heat pump characteristics and heating energy consumption. Results show that, for the direct connected water heating system, the heat pump consumes the least energy with the integrative flow regulation mode under relatively lower outdoor air temperature condition, and it also consumes the least energy with the regulation mode of centralized regulation with flow varied by steps under relatively higher outdoor air temperature condition.
