摘要
在建筑供热空调中采用热泵技术可以有效地提高一次能源利用率,减少温室效应气体CO2和其他大气污染物的排放。本文阐述了利用热泵供热比锅炉直接燃烧供热节能的原理,对主要的热泵供热形式,特别是地源热泵的技术特征、适用范围和经济性作了较详细的介绍。
Utilizing heat pumps for heating and air-conditioning in buildings can make more efficient use of the primary energy sources and substantially reduce emissions of carbon dioxide and other atmospheric pollutants. The reasons why heating by heat pumps is superior in the sense of energy efficiency to that by direct combustion of fuels was explored. Different kinds of heat pump systems for building HVAC were expounded such as the air source heat pump,the groundwater heat pump, the surface water hear pump and the ground-coupled heat pump with their respective advantages and limitations. Emphases were put on application of the ground-coupled heat pump systems, whose technical characteristics, applicability and economic competitiveness were discussed in comparison with traditional HVAC systems.
