适用于寒冷地区的太阳能与低温空气源热泵复合空调系统
Low temperature air-source heat pump system combined with solar energy for cold areas
摘要：
针对我国寒冷地区的气候特点，提出太阳能复合低温空气源热泵的供暖系统形式，并介绍了系统组成和全年主要的运行模式。以乌鲁木齐市某住宅建筑为对象，分析该系统在寒冷地区应用的可行性。由分析结果可知，与热网供暖和分体空调器制冷的组合系统相比，该系统的运行费用大大降低，系统投资回收期约为5.9 a，节能率约为12.7%。

Abstract：
According to the climate characteristics of cold areas in China, proposes the low temperature air-source heat pump (LTASHP) system combined with solar energy, and describes the components and main operation modes of the system of a year. Taking a residential building in Urumqi as object, analyses the applicability of the system in these areas. Compared with heating network combined with room air conditioners for heating and air conditioning, the operation expense reduces significantly, the energy saving rate is about 12.7% and the payback period of investment is about 5.9 years.
