<p>PROBLEM TO BE SOLVED: To provide a total enthalpy heat exchanger capable of reducing a leakage amount of air in a cross portion between an exhaust side passage and an air supply side passage and improving airtightness.SOLUTION: The total enthalpy heat exchanger is configured so that moisture-permeable partition plates 1 and spacing plates 2 maintaining channel height are alternately and adhesively bonded and stacked, and so that an air supply side passage S and an exhaust side passage E are formed among the partition plates for heat-moisture change via the partition plates 1. Chamfered portions 3 are formed in cross portions between an air supply ventilation surface through which supplied air passes and an exhaust air ventilation surface through which the exhausted air passes cross each other, respectively, and covers 4 shaped to cover the chamfered portions 3 are provided on the respective chamfered portions.</p> |
