新型混合地源热泵的土壤热平衡性能模拟

Soil Thermal Balance Performance Simulation of the New Hybrid Ground Source Heat Pump

地源热泵是一种新型节能环保的绿色能源利用技术,在应用过程中,存在的较大问题之一就是对土壤的吸放热不平衡。针对此问题本文提出了一种新的混合地源热泵形式,将热水系统和地源热泵空调系统进行耦合,对长沙某宾馆进行了系统设计并用TRNSYS进行了长达30年的模拟。通过和传统单一的地源热泵空调系统比较,证实了该系统不仅能有效地解决土壤吸放热不平衡问题,而且有效地提高了机组的运行效率。

Ground source heat pump is a new kind of green energy technologies which is advantage in energy conservation and environmental protection. One of the severe problems in the process of application is the thermal imbalance of the heat absorption and release to the ground. To solve this problem, this paper presents a new type of hybrid ground source heat pump in which hot water system is combined with air conditioning system of ground source heat pump. As an example, make a simulation of a newly designed air conditioning system of a hotel in Changsha. By comparison of the conventional single ground source heat pump, this new hybrid ground source heat pump has been confirmed to solve the imbalance of the heat absorption and release to the ground, effectively improved the operation efficiency of air conditioning unit meanwhile.
