UK application of direct cooling ground source heat pump systems.

Author(s) : SPITLER J.

Summary

One form of ground-source heat pump (GSHP) system that appears promising for UK application is a system where building heating is provided via one or more water-to-water heat pumps coupled to the space heating system. Building cooling may be provided circulating water directly between the ground loop heat exchanger and chilled ceilings or beams. In this system, the heat extracted from the ground for heating is replaced during the cooling season. The paper presents a simulation methodology for GSHP systems, and examines a potential system for a five-story office building in Newcastle. A building simulation model is used to provide hourly building heating and cooling loads for a typical meteorological year. The system simulation is then used to predict system performance and long-term temperature response of the ground. Energy consumption for this system is compared to that of a conventional system with condensing gas boilers and vapour compression refrigeration.
