Betriebsverhalten einer Wärmepumpenanlage mit Luftkollektor und Erdspeicher

Abstract

This study is concerned with the investigation of the performance of a heat pump system with solar air heater and earth storage as a source of heat. After the experimental check of the collector and the earth storage a complete heating system was constructed and studied over a heating period. The heating system was simulated by a computer program. This program treats the solar air collector and the earth storage by the measured characteristics of their performance. A house simulation program used the ambient temperature, the solar radiation and wind speed to calculate the heating load of a residental house. The calculations resulting from the simulation program showed the performance of the system under the different weather conditions of Jülich and Hamburg as well as the suitable regulation and the right dimensions of the mean components
