摘　　要：超低温空气源热泵凭借其运行的经济性、环保性,是“双碳”政策下力推的节能型高效设备。空气源热泵不同于锅炉,其供热能力受环境温度影响较大,且单台设备基本无负荷调节能力,流经热泵的最小流量与用户末端需求流量也不一致,给输送系统选择造成较大的困扰。空气源热泵供暖循环系统有单循环与双循环两种形式,河北南宫市丽滨佳苑小区采用单循环形式,水泵耗电量超出预期145%。本文将结合河北南宫市空气源供暖项目分析两种系统形式的适应性。Due to its economy and environmental-friendly features, the ultra-low temperature air-source heat pump is referred as an energy-saving and high-efficiency equipment under the "Double Carbon" policy. Unlike the boiler, the output of air source heat pump is greatly affected by the ambient temperature, and a single equipment basically has no load regulation capacity. The minimum flow through the heat pump is also inconsistent with the end flow of users, causing great trouble for the selection of transmission system. There are two forms of air source heat pump heating: single circulation and dual circulation.Libin Jiayuan community of Nangong City in Hebei Province adopted single circulation, and the power consumption of the heat pump was 145% higher than the expectation. Combining with the air source heating project in Nangong City, this paper analyzes the adaptability of the two system forms.
