Simulations of a roof space collector system for a multi family house for preheating of domestic hot water

Abstract

A summary of the results from computerized simulations carried out on a roof space solar collector system for a residential house in Herlev about 12 km east of Copenhagen in Denmark. The simulations have been carried out in order to define the design and size of the components of the solar heating system. It will be installed on some of the 18 blocks of the built-up area named ``Toftegaard`` owned by the co-operative housing society of 1944 in Herlev. The first solar heating system will be installed on an east-west orientated building containing 16 flats. The system will, however, also deliver domestic hot water to 72 other flats. The roof space collector system will serve as a preheater for the existing domestic hot water system. It will utilize the attic of the building for collecting heat from the sun. In its most simple form a roof space collector consists of the attic of the building divided into a north and south facing part. The normal roof of the south-facing roof is replaced by a transparent cover and the wall and floor of the attic is painted black. The hot air of the roof space can either be used directly for  More>>

In its most simple form a roof space collector consists of the attic of the building divided into a north and south facing part. The normal roof of the south-facing roof is replaced by a transparent cover and the wall and floor of the attic is painted black. The hot air of the roof space can either be used directly for space heating or the heat from the collector can be transferred to a liquid based system by means of an air to water heat exchanger, as in this case. The water heated by the air to water heat exchanger will be stored in a water tank in the basement. The system itself and the methods of simulation are described in more detail. The simulation programme is presented in the appendix. (AB).}
