<p>A heat transfer medium supplying an air heater (3) is carried in a heat circuit (16). A thermal store (18) is provided at a heat exchanger for heating the medium, or between the heat exchanger and the air heater. The heat exchanger is supplied from a heat pump circuit (11) which is also connected to an air cooling device (5). The extracted heat from cooling is pumped from here into the heat exchanger of the heating circuit.</p> |
