Tools for ground source heating anc cooling based on closed loop boreholes
The objective is to pave the way for a wider application in Denmark of heat pump systems based on closed loop boreholes - a technology with potential for CO2 reductions and energy efficiency. The project will develop knowledge, tools and best practice for planning and designing installations and provide education and dissemination of results
Heat pump systems based on closed loop boreholes, is a technology with potential for CO2 reductions and energy efficiency, but the application in Denmark is limited compared to our neighbour countries. There is a lack of knowledge and experience and the project objective is to pave the way for a wider use by providing knowledge, tools and best practice for planning and designing installations. The main elements of the project are: - Collection and analyses of existing information and experience and identification of key parameters for planning, designing and installing heat pump systems based on closed loop boreholes; - A comprehensive mapping and measuring program of surface temperatures, temperature gradients and thermal properties of different soil types and materials; - Optimization of system design with respect to environment and economy based on actual installations and test sites, including drilling and completion of boreholes, system control, analysis of energy balance, energy storage (heating and cooling) and modelling of heat and fluid flow; - Construction of a database with results of information gathering, measuring programme and mapping efforts; - Dissemination activities including user interface for database, course material for training and education, workshops and seminars, technical guidelines and recommendations for legal framework
The project has developed a web-tool that provides access to a large amount of usable knowledge concerning Danish earth thermal properties. The tool is available for free at GEUS homepage. The available knowledge can be used as basis for commercialized projects and strengthening of already existing business areas. The involved knowledge institutes have with impetus in the project created breeding ground for new development and demonstration projects, there has also been establish contact with foreign science institutes in the field.
The project has contributed to verification of methods and to demands on thermal conductivity witch forms a central element in a robust decision making.
