GROUND SOURCE HEAT PUMPS
January 1, 2010 - BRE

INTRODUCTION Cutting CO2 emission levels by 80% by 2050 is no easy task, and is now an international objective following the agreement reached by the G8 nations in July 2009. If businesses are to succeed in hitting the target, they will have to make significant changes to all aspects of their...

ASHRAE OR-16-C045 - Energy Use of Ground-Source Heat Pumps for Various Load Temperatures
January 1, 2016 - ASHRAE

This paper examines the impact of the secondary fluid temperatures at the evaporator and condenser on the energy use of water-to-water ground-source heat pumps (GSHP). In the first part of the paper, the energy consumption reduction associated with small temperature...

ASHRAE OR-16-C044 - In-Situ Testing of Shallow Depth Helical Heat Exchangers for Ground Source Heat Pump Systems
January 1, 2016 - ASHRAE

This paper explores the performance of shallow depth helical heat exchangers coupled with ground source heat pumps (GSHP) for residential HVAC applications. These vertical helical heat exchangers occupy considerably less land when compared to horizontal...

ASHRAE OR-16-C043 - Deep Boreholes for Ground Source Heat Pump Systems – Scandinavian Experience and Future Prospects
January 1, 2016 - ASHRAE

Ground source heat pump (GSHP) systems are commonly used in Sweden for both residential and commercial buildings. However, there are several key differences compared with GSHP systems utilized in the USA. Scandinavian systems are often heating-only, and instead of using...
