Abstract. A thermal response test (TRT) apparatus is introduced in this paper for determination of the performance of underground heat exchanger in ground-source heat pump system. The inlet and outlet temperatures of the underground heat exchanger can be real-time tested to obtain the heat transfer data. The apparatus was used to test a underground heat exchanger for its inlet and outlet temperatures in Red Star farm, Beian City, Heilongjiang province, China. The inlet and outlet temperatures varied in the ranges of 10.62~13.57°C and 9.01~11.88°C within 24 hours, respectively.

In this paper, a hotel with hybrid geothermal heat pump system (HyGSHP) in the Pensacola is selected and simulated by the transient simulation software package TRNSYS [1]. To verify the simulation results, the validations are conducted by using the monthly average entering water temperature, monthly facility consumption data, and etc. Three types of HVAC systems are compared based on the same building model and HVAC system capacity. The results are presented to show the advantages and disadvantages of HyGSHP compared with the other two systems in terms of energy consumptions, life cycle cost analysis.

Comparative Life Cycle Assessment

Ground source heat pump (GSHP) systems are an extremely efficient space heating and cooling technology. There is a large consensus throughout the literature that GSHP systems can reduce operational CO2 emissions by up to 80% in comparison to natural gas furnace (GF) and air conditioner (AC) systems. The literature is limited; however, in regards to the specific environmental impacts associated with the systems, as well as the impacts that occur throughout the systems’ entire life cycle. In this project, a comparative life cycle assessment was conducted to compare a GSHP system with a GF/AC system, examining 14 specific environmental impact categories. Results were consistent with the literature in regards to the operational stage; however the GSHP system displayed a significantly greater overall environmental impact. While these results are specific to the region of Ontario, Canada, they call into question the prevailing opinion that GSHPs are the more environmentally sustainable option.
