1,072,092. Ventilation. ESSO RESEARCH & ENGINEERING CO. May 20, 1964 [May 20, 1963], No. 19478/64. Heading F4V. In the regenerative ventilation of an enclosure 10 air flow through regenerators 21, 22 is reversed periodically to maintain desired conditions in the enclosure and additional air is passed into the enclosure through a duct 23. The regenerators contain a heat transfer and/or gaseous impurity or water vapour removing packing. The additional air flow may be dry or wet. The regenerators conserve heat in the enclosure, the humidity of the enclosure is controlled by the humidity of the additional air stream and, when activated carbon is used in the regenerators, carbon dioxide and ethylene are preferentially vented to atmosphere. An air withdrawl duct (24), Fig. 3 (not shown), may be included and a dehumidifier (25) may be located in the enclosure. The Specification lists preferred regenerator packings and discloses experimental data. |
