Total, or enthalpy, recovery also transfers moisture, which is valuable in humid climates where both temperature and humidity loads are high.<\/p>\n<p><strong>Which design suits buildings better, plate or rotary?<\/strong><br \/>Plate exchangers are simple, leak-tight, and good for moderate airflows. Rotary wheels suit larger volumes and can recover humidity, at the cost of slight stream carry-over.<\/p>\n<p><strong>Does recovery also improve comfort?<\/strong><br \/>Yes. By pre-conditioning ventilation air, it stabilizes indoor temperature and humidity and reduces the size of the heating and cooling plant needed.<\/p>","protected":false},"excerpt":{"rendered":"<p>Why Ventilation Wastes Energy Buildings need fresh air, but exhausting conditioned indoor air and bringing in untreated outdoor air can waste a large share of heating and cooling energy.
