Document Type and Number:
Japanese Patent JPS6150213
Kind Code:
B2
Abstract:
A ventilating system including a heat exchanger utilizing boiling and condensation of a liquid mounted in a cabinet formed with a first air passage and a second air passage by a partition plate extending horizontally across the heat exchanger substantially in the center thereof. At least one air sucking and exhausting fan is mounted in one of the first and second air passages, and the heat exchanger is provided with at least one auxiliary heat exchanger operative to perform space cooling or space heating. The first and second air passages are each provided with ventilating ports for effecting heat recovery, ventilating ports for effecting cooling by ventilation and a ventilating port for allowing cooled air or heated air to flow therethrough, so that the ventilating system can be operated in a heat recovery mode, a cooling by ventilation mode and a space cooling or space heating mode by actuating the auxiliary heat exchanger and suitably opening and closing various ventilating ports.
