FIELD: air-conditioning plants including those incorporating oxygen-enriching devices. ^ SUBSTANCE: proposed air-conditioning plant has outdoor module incorporating external heat-transfer apparatus providing exchange between heat-carrying agent and outdoor air; indoor module incorporating internal heat-transfer apparatus affording heat transfer between indoor air and heat-carrying agent; and device for feeding oxygen-enriched air incorporating air compressor that produces compressed air; oxygen-enriched air separator that functions to separate compressed air into oxygen-enriched air and nitrogen-enriched air; as well as pipe feeding oxygen-enriched air coming from oxygen-enriched air separator to indoor module; oxygen-enriched air separator has main casing, oxygen-enriched air outlet channel for passing oxygen-enriched air through delivery pipe, nitrogen-enriched air outlet channel for discharging nitrogen-enriched air into atmosphere, separating diaphragms for separating compressed air into oxygen- and nitrogen-enriched air; internal part of main case is divided into first space communicating with nitrogen-enriched air outlet channel and second space communicating with internal oxygen-enriched air outlet channel; it also has pressure control unit that functions to maintain desired pressure drop between first and second spaces above preset level. As an alternative, proposed plant can be provided in addition with heating appliance for heating separating diaphragms to desired temperature to improve selective penetrability for oxygen of separating diaphragms. ^ EFFECT: ability of oxygen-enriched air separator to maintain pressure drop between first and second spaces. ^ 12 cl, 6 dwg |
