Suitability Analysis of Low Temperature Air Source Heat Pump Applied in the Region of Xingtai

介绍了低温空气源热泵系统的原理和适用情况,对低温空气源热泵系统在不同运行控制策略下的经济性和供热特性进行了分析,结果显示在满足采暖需求的条件下,不同运行控制策略对系统的运行费用有明显影响,得出了不同运行时长、不同入住率时系统经济效益平衡点;分析并对比了6种典型供热方式的节能性,结果表明在相同的供热条件下,低温空气源热泵系统在节能方面具有明显优势,其单位供热面积年标准煤消耗量为9.15kgce/(m^2·a),是传统燃煤锅炉能源消耗量的55%~66%,一次能源利用率略低于燃煤热电联产,证实采用低温空气源热泵系统在邢台地区冬季供暖可行。

The principle and application of the low temperature air source heat pump system are introduced.The economics and heating characteristics of the low temperature air source heat pump system under different operation control strategies are analyzed.The results show that under the condition of satisfying the heating demand,different operation control strategies have a significant impact on the operating cost of the system,and the daily working times of the system that meets the balance of economic benefits at different occupancy rates are obtained;Analyses and compares energy consumption of 6 typical heating systems.The results show that under the same heating conditions,the low temperature air source heat pump system has obvious advantages in energy saving.The annual standard coal consumption per unit heating area is 9.15 kgce/(m^2·a),which is 55%~66%of the energy consumption of traditional coal-fired boilers.the primary energy efficiency of which is slightly lower than of coal-fired cogeneration,which proves that the use of the low temperature air source heat pump system is feasible in winter in the region of Xingtai.
