PCT No. PCT/SE84/00388 Sec. 371 Date Jul. 11, 1985 Sec. 102(e) Date Jul. 11, 1985 PCT Filed Nov. 14, 1984 PCT Pub. No. WO85/02247 PCT Pub. Date May 23, 1985.Method and device for operation of a heating plant comprised in a heating system which works with circulation of air. A partial flow (16) of the consumed air in the heating system is supplied to a heat exchanger (4) for heat exchange with intake air (12) coming from outside and with a return flow (14) of circulation air from the heating system. After passage through the heat exchanger (4) the mixture of intake air and return air is fed as heat delivering medium to the evaporator in a circulation heat pump (5). The quantity of air circulating through the heat pump is kept greater than the partial air flow which is exhausted from the heating system via the heat exchanger. With increasing demand for energy the partial flow is exhausted by means of a suction fan (7) and can, in addition, be mixed with the flue gases from a preferable water-carried heating boiler (2). |
