Experimental and Numerical Investigations of Heat Exchangers in Ice Storages for Combined Solar and Heat Pump Systems
Abstract
In the present paper different heat exchangers designed to be installed into an ice storage for solar and heat pump heating applications are experimentally investigated. Analyzed heat exchangers are capillary mats and flat plate types. For each heat exchanger, different designs, materials and number of heat exchanger units are evaluated using two different mass flows. This paper aims at i) characterizing different heat exchanger designs by means of measurements in a laboratory-size ice storage of 2 m3, ii) determine specific advantages and disadvantages of different heat exchanger concepts for ice storages used in combination with solar collectors and a heat pump and iii) provide a source of experimental data for model validation.
