Abstract

A new integrated modeling and initial commissioning technology have been investigated to introduce and disseminate a more energy and cost efficient way of CO2 free GSHP (Ground Source Heat Pump) heating and cooling system for multi-family residential applications. A system modeling of key components such as heat pump, ground heat exchanger and a heat exchanger inside a RWST (Rain Water Storage Tank) for a multi-family building has been conducted and expressed as mathematical equations with EES (Engineering Equation Solver) tool and would be validated with a 10 kW (3RT) lab scale system Integral Effect Test (IET). Key results indicated that the effect of the rain water temperature on cooling and heating capacity could be visualized and also a heat pump performance data based commissioning technology could enhance the credibility of the complex integrated system properly as predesigned intentionally. This new integrated concept of a GSHP with RWST for the multi-family residential building could be the one of solutions for the CO2 free energy issues for Seoul and major cities and communities expecting more clean energy societies.
