Abstract (en)
[origin: EP1921401A2] The method involves arranging an evaporator in an inner space of a building and acts as cooling position and has an external heat exchanger (44) arranged outside the building. A part of the heat of the cooling agent carried in the pressure line (24,24') by an internal heat exchanger (26) is used for heating the inner space of the building. The internal heat exchanger is connected with the pressure line and arranged before the condenser (36) relative to the flow direction of the cooling agent. An independent claim is also included for a refrigerating plant with heat recovery.
