ÉCHANGEUR DE CHALEUR À PLAQUES ET MACHINE DE RÉFRIGÉRATION RÉVERSIBLE COMPRENANT UN TEL ÉCHANGEUR

摘要

This exchanger (1100), including superposed plates (2A-2L) which are inserted between two end plates (11, 12) and which define channels for circulation of heat-exchanging fluid. These channels delimit a first circuit (C1) for circulation of a first heat-exchanging fluid, comprising a single pass, and a second circuit (C2) for circulation of a second heat-exchanging fluid, comprising two passes opposite one another, so that, for each direction of circulation of the second heat-exchanging fluid in the second circuit, one of the two passes of the second circuit is co-current with respect to the pass of the first circuit, while the other of the two passes of the second circuit is counter-current with respect to the pass of the first circuit.
