地源热泵空调机组连续运行过程仿真与经济性分析
Process simulation and economical efficiency analysis of ground-source heat pump air-conditioning unit under continuous operation mode
摘要
Abstract
A mathematical model was build to modeling a ground source heat pump (GSHP) with cooling capacity rating of 5 kW, which was used to simulate the process of ground-source heat pump air-conditioning under the mode of constant 、stable、 continuous cooling supply in summer, to reveal the influence of characteristics of ground-coupled heat exchanger on GSHP air conditioning unit. It was evident that, energy consumption and COP of GSHP air conditioning unit were always in change,which could be divided into three stage: rapidly changing stage, transition stage and turning to steady stage. There was still some superiority than air source heat pump (ASHP) air conditioning unit, even the differences of energy consumption and COP in the 3 stages were obvious. The energy consumption and COP in the stage turning to steady should be taken as the basis for GSHP air conditioning unit's selection under continuous operation mode.关键词
