Radiant Heating-cooling Performance Assessment in a Shopping Center in Sopron- Hungary

Abstract

In this study performance of a radiant heating-cooling via air source heat pump was investigated. This study is part of a project funded by European Union's FP7 for research technological development and demonstration. In the project it is aimed that a holistic retrofitting solution for commercial buildings to reduce primary energy consumption down to less than 80 kWh/m(2) per year. A shopping center called IKVA located in Sopron Hungary used as a demo building. In that building a heat pump system integrated with a radiant heating and cooling system is used. In this paper two different cases are compared regarding air source heat pump system, in Case-1 air source of the heat pump is outdoor air in Case-2 air source of heat pump is return air.
