摘要：

地埋管地源熱泵系統(tǒng)是一種高效節(jié)能的空調(diào)供暖方式。在地下管道中流動的水通過土壤吸熱或排熱，實現(xiàn)室內(nèi)舒適的溫度控制。本文選擇了套管式地埋管地源熱泵系統(tǒng)為研究對象，建立了水熱耦合數(shù)值模型，分析了地表土壤層的溫度分布、熱平衡狀態(tài)以及熱泵系統(tǒng)的運行效果和能耗情況。研究結(jié)果表明，套管式地埋管地源熱泵系統(tǒng)在不同氣候條件下均能實現(xiàn)穩(wěn)定、高效的空調(diào)供暖效果，并且系統(tǒng)地面溫度變化小，不會造成生態(tài)環(huán)境影響，因此具有廣泛的應(yīng)用前景。
