<p>The combination contains single- or multi-stage refrigerator and single- or multi-stage heat pump; and generates cold or heat, while utilizing natural heat. The cycle transmits heat from refrigerator to heat pump, while cold from the latter is transmitted to the refrigerator. The heat from the refrigerator is preferably transfered by slightly warmed cold service water. The latter may be heated by the heat pump and used for heating household water, also for heating purposes. The generated heat, or cold, may be suitably stored prior to actual use. Backflow hot water may be utilised e.g. for a swimming pool, in combination with nature resources.</p> |
