<p>Heating systems of this kind use the waste heat generated inside the unit. The requisite mixing of different waste heat flows results in heat losses which are very largely eliminated by the present invention. It is proposed that all suitable heat flows are led firstly into single-stage or multi-stage heat exchangers and into direct heat exchange with mediums to be heated, the residual energy then being used to evaporate the refrigerant in the single-stage or multi-stage heat pump evaporator. All available heat flows are used at the highest possible temperature level and only heat flows at identical or similar temperature levels are mixed and used at the next lower temperature level. Certain heat exchangers (20, 21) and evaporators (10, 11, 26, 27, 28) are designed in multiple stages and allocated in a specific way to the air ducting lines (17, 18, 19, 22, 29, 32, 37).</p> |
