Device for increasing the heating and cooling output of a heat pump in heat reclamation in air conditioning units

Abstract

In order to improve heat reclamation, a circulatory composite system having one heat exchanger each in a supply air volume flow and an exhaust air volume flow is provided in an air treatment system and connected to a buffer reservoir supplied by a heat pump with heat energy. In addition, a method for operating a heat reclamation system with the structure of a circulatory composite system with an integrated heat pump is designed such that the volume flow of the heat exchanger is divided in the line leading to the heat exchanger. The at least two volume flows serve to flow through the heat exchanger (compressor) of the heat pump with a larger or smaller volume flow than the heat exchanger in the supply air.
