20090277203 | DEVICE FOR HEATING, COOLING AND PRODUCING DOMESTIC HOT WATER USING A HEAT PUMP AND LOW-TEMPERATURE HEAT STORE - A heating device includes a low-temperature heat store thermally coupled to a heat pump. The heat store is a buried pocket containing a permeable material and water. A high heat exchange capacity is thus achieved by exploiting both the high specific heat of the water and the high latent heat of liquefaction of the water contained in the heat store. | 11-12-2009 |
