Water tempered air conditioning system with condensation heat recovery

摘要

Air conditioning system consisting of 3 plate heat exchangers (A, B, C), 4 fans (5,6,7,8) or blowers and 4 control elements (V1, V2, V3, V4) and external cold or hot water supply (3a, 3b, 3c , 3d, 3e), wherein the first heat exchanger (A) is an air-air heat exchanger with Kondensationswasserrückführung (4a) in the exhaust air (1d), the second heat exchanger (B) an air-water plate heat exchanger to dew point reduction of the fresh air (2b) where the condensed water (4b) is also evaporated in the exhaust air (1d) of the first heat exchanger (A), and the third heat exchanger (C) is an air-water plate heat exchanger for indoor air cooling (13), these three heat exchangers (A, B (C) being integrated in a system so as to form a single block of slabs with substantially horizontal plates (9, 10), where on each plate one sector is assigned to each of the three heat exchangers involved and connecting channels are interconnected by webs (11) defines si nd, so that the sectors and the connection channels of the individual plates are congruently superimposed.
