A municipality water reticulation R22 ground-coupled reversible heat pump, was investigated as an alternative to conventional air source systems. The study covers the testing of a heating and cooling system that utilises the ground as its source. The ground source comprises of a municipality water supply line that is modified to allow water to flow through the outdoor coil thus delivering or extracting heat from the system. The investigation was conducted by developing analytical models that were used for the design of a ground-coupled reversible heat pump and a conventional, also reversible air-to-air system. The models were verified with a commercially available computer program as well as with measurements on the two systems. The results show an overall increase in performance with the use of a ground source system over the conventional air source systems. Thus the ground-coupled reversible heat pump system can provide a cost effective alternative to the more conventional air-to-air systems.

Future Work

This paper discusses the research and the state-of-art practices on ground source heat pump systems (GSHP) in China. It introduces the Chinese patents on GSHP. The GSHP development policies of China, including incentive mechanism, relevant codes and regulations, are also introduced. In addition, this paper discusses and summarizes the shortages and imperfects of the current research of the GSHP system and gives some recommendations for future work. At last, the authors give some advice for the development of ground source heat pump. For more reliable statistics on geothermal energy use, the obligation to supply an installation report to the relevant authority should also be imposed on the rural buildings besides urban buildings. GSHP systems are suitable for heating and cooling of buildings and so could play a significant role in reducing CO2 emissions.

Rules Of Thumb

The lack of a computerized approach to optimally size hybrid Ground Source Heat Pump (GSHP) systems leaves a glaring gap in our knowledge of their benefits when utilized in an urban environment. To address this issue, this study introduces two new, robust methodologies, one for determining optimal GSHP size as part of a hybrid system for an individual building and one for assessing the appropriateness of combining multiple buildings onto a single hybrid GSHP system. Both methodologies simultaneously consider heating and cooling and are applicable to residential, commercial and industrial buildings that are either heating or cooling dominant. Using these methodologies can result in significant reductions in initial costs of installation, payback period, and operation costs, when compared to following rules of thumb or using non-hybrid systems. In most cases, when optimization is performed, the GSHP meets very large portions of the total annual heating and cooling demand of buildings.

Heating Mode

The performance of vertical and horizontal ground loops coupled to a Ground-Source Heat Pump (GSHP) was investigated under four different scenarios. For this purpose, an experimental set-up was designed and constructed at the Archetype Sustainable houses in Vaughan, Ontario, Canada. In the first two tests, the two vertical ground loops coupled to the GSHP were tested in heating, and cooling modes. In heating mode, the GSHP COP ranged between 2.7 and 3.15. In cooling mode, the GSHP performed better than the heating mode with COP range of 3.75 and 5.4. In the last two tests, two scenarios were tested to compare the horizontal and the vertical ground loops in cooling mode. In the first scenario, the ground loop flow was divided equally between the loops and the GSHP overall COP was 5.42. The last test used equal Reynolds number in both loops and the GSHP overall COP was 5.36.
