JPS5585889A - Heat exchanger - Google Patents

Abstract

PURPOSE: To air condition and ventilate air in one heat exchanger by heat exchanging with three passages of outer atmospheric air passage and chilled or hot air passage, an indoor air exhaust passage, and a heat source flow passage.

CONSTITUTION: When dry and low temperature air is flown through a primary passage (outer atmospheric air passage) 14, high temperature and moisture air is through a secondary passage (indoor air passage) 16, and hot water is flown through a tertiary passage (hot source passage) 20, heat and moisture are transmitted through heat exchanging plates 6, 5 of sensible and latent heats of heat exchanging materials 13 from the air in the secondary passage to the air in the primary passage to become substantially the air state at the intake air port 17 of the secondary air flow inlet. The hot water in the passage 20 transmits its heat to the primary passage 14 via fins 7. That is, higher heat is transmitted than the hot water in the passage 20 to the air in the passage 14, both the heat and moisture are transmitted simultaneously from the hot and moistened air in the passage 22 to the air in the passage 14 to thus diffuse suitably conditioned air from the outlet 15 of the passage 14.
