Energy flow Analysis of Ground Source Heat Pump Central Air Conditioning System Under Heating Mode

在满足空调供热区域热舒适性的前提下,建立了土壤源热泵热水机组集中空调系统的能流分析平衡方程,阐述了从土壤源中提取热量到最终将热量输送到空调房间的4个子系统环路能流情况,将空调供热系统各环路的能流可视化。并以深圳某大型酒店为例,绘制了该酒店土壤源热泵集中空调供热系统某一运行工况的实际能流图,定量分析了系统各部分能流的组成、大小、方向,以及各能流之间的关联性,分析了降低系统能耗的主要影响因素,为土壤源热泵集中空调系统的节能降耗提供依据。

To meet the air conditioning heating area thermal comfort, established the analysis of energy flow balance equation of central air conditioning system of ground source heat pump, introduced to the flow of extract heat from the soil source from the final heat transfer to the 4 loop subsystems in air conditioning area, visualized each loop heating air conditioning system energy flow. A large hotel＇s central air conditioning system of ground source heat pump in Shenzhen as an example, the actual energy flow diagram of the hotel soil source heat pump central air conditioning system of a running condition was drew. The quantitative analysis of the composition, size and direction of each part of the system of energy flow, and the correlation between flows was discussed. Analyzed the main influencing factors to reduce the energy consumption of the system, and provide the basis for energy saving of air conditioning system for ground source heat pump.
