<p>A heat pump cooling effect and heat factor rises sharply as a function of the evapn. temp. at constant condensing temp. In order to recover as much heat as possible from e.g. combustion gases, it is necessary to work with a low evapn. temp. The system makes it possible to recover heat which requires a low evapn. temp. and for the heat pump to work with a high average heat factor. On the heat carrier side, accumulators are used with a mixt. valve. A control system prioritises the charging of the accumulators in a sequence which gives the highest average effect and heat factor.</p> |
