摘要
地源热泵系统通过循环液在封闭的地下埋管中流动,实现系统与大地之间的换热,利用大地岩土层中的可再生热能。由于较深的地层中在未受干扰的情况下常年保持恒定的温度,与室外气温相比是冬暖夏凉,因此地源热泵可克服空气源热泵的技术障碍,且效率大大提高。在热泵机组中消耗1kW的电能可以得到4kW以上的热量,即能效比大于4。它是一种可持续发展的建筑节能新技术。
GSHP (ground source heat pump)system circulates fluid flow in the buried sealed pipes underground to realize heat exchange between GSHP system and the earth, using renewable energy in the geotechnical layer.Without interference in the deep strata condition, the ground keeps constant temperature throughout the year, compared with the outdoor temperature, which is warm in winter and cool in summer.So the GSHP ground source heat pump can overcome technical barriers of ASHP air source heat pump and its efficiency is greatly increased. GSHP unit can obtain 4 kW heat when consuming 1 kW power, which means its COP is more than 4. GSHP is a new sustainable building energy-saving technology.
