The article describes the advantages of heating designed as a system. It shows (among others) the features of balanced ventilation systems with heat recovery and compact ventilation appliances (heat recovery from ventilation exhaust air through a heat exchanger and a heat pump, to provide warm fresh air and domestic hot water).
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.
