Advanced Supermarket Refrigeration/Heat Recovery Systems. Country Report, Denmark

Hans-Jørgen Høgaard Knudsen, K. G. Christensen

Research output: Book/ReportBook


Annex 26 is the first international project under the IEA Heat Pump Programme that links refrigeration and heat pump technology. Recovering heat from advanced supermarket refrigeration systems for space and water heating seems obvious and is beneficial for owners and operators. Because the great number of supermarkets that offer frozen and chilled food and further growth of this sector may be expected, the amount of energy used for refrigeration is enormous and will likely increase in the near future. Annex 26 analysed several advanced supermarket refrigeration systems and came to remarkable conclusions as far energy conservation and TEWI reduction is concerned. The conclusion justify that advanced supermarket systems with heat recovery should receive great attention and support. And there is still further research needed in several areas. The Annex also included a thorough system analyses and proposals for cost reductions are given. Annex 26 has produced three deliverables: 1. workshop (October 2000) proceedings Stockholm, Sweden (CD-ROM)-HPP-AN26-1 2. Final report Volume 1 Executive Summary (book)-HPP-AN26-2 3. Final report Volume 2 Country reports (CD-ROM)-HPP-AN26-3. Each of the reports provide valuable information for practitioners (designers, installers) and manufactures of supermarket refrigeration systems.
