A performance comparison between an air-source and a ground-source reversible heat pump.

Author(s) : SWARDT C. A. de, MEYER J. P.

Summary

In the study, the performance of a reversible ground-source heat pump, coupled to a municipality water reticulation system, is compared experimentally and with simulations to a conventional air-source heat pump for space cooling and heating. A typical municipality water reticulation system comprises hundreds of kilometres of pipes designed in loops, that will ensure adequate circulation of the water. This result is in a substantial heat exchaner with great potential. Indirect heat transfer occurs between the refrigerant and ground via the municipality water reticulation system that acts as the water-to-ground heat exchanger. The experimental and simulated comparisons of the ground-source system to the air-source system are conducted in both the cooling and heating cycles. Climatological statistics are used to calculate the capacities and COP of the ground-source and air-source heat pumps. Results obtained indicate that the utilisation of municipality water reticulation systems as a heat source/sink is a viable method of optimizing energy usage in the air-conditioning industry, especially when used in the heating mode.
