一种基于土壤源热泵的空调制冷供暖系统研究

Research on air-conditioning refrigeration and heating systembased on ground source heat pump

本文提出了一种基于土壤源热泵的空调制冷供暖系统:夏季制冷,利用土壤提供冷源,末端采用毛细管网呼吸式重力空调墙装置,直接供冷方式,无需制冷机组;冬季供暖,利用土壤提供热源,末端采用毛细管网换热器。该系统虽然造价略高,但节能且运行成本低,能维持地下土壤的热平衡,有利于系统的长期稳定运行。

In this paper,an air conditioning heating and cooling system based on ground source heat pump was proposed.In summer,the soil is used to provide the cooling source.The capillary-network breathing gravity air conditioning wall device is used at the end of the system,and the direct cooling mode is adopted without refrigeration unit.In winter,soil is used to provide heat source,and capillary network heat exchanger is used at the end.Although the cost of the system is a little high,it is energy-saving and low operation cost.It can maintain the heat balance of underground soil,which is conducive to the long-term stable operation of the system.
