Using a newly developed simulation model for electricpowered compression heat pumps, ventilation modules with an integrated exhaust air heat pump for supplying heat for passive solar houses are studied. New units are tested in the conception and design phase. Different designs can be compared before readings are taken from the first prototype. The capacity of the method is tested and the simulation model is validated on the example of a simulated integrated ventilation and heat supply unit for passive solar houses that is intensively measured.
Compact ventilation appliances appeared on the market for solar passive houses. They include a heat pump to transfer heat from ventilation exhaust air to fresh air and/or domestic hot water. This article is the second part of a serie of two. It continues to describe a model for simulating the operation and performance of such appliances which was developped to be used in the TRNSYS software environment. It compares the results of calculations with those of laboratory measurements.
