The concentration of CO 2 and N 2 increased in, and the oxygen partial pressure decreased relatively, which could cause health problems. The present invention provides a loop for continuously processing a part of the circulating air in a room, and removes most of H 2 O, CO 2 , CO and N 2 from the air, thereby achieving a relatively high oxygen enrichment. The aim is to produce conditioned air, and as a result to keep the room comfortable without ventilation and to enhance the cooling and heating effect.

完全燃焼が起きた場合にはCOが発生する。When humans and other animals live in the house or use a gas stove or other combustor, indoor oxygen decreases while C
O 2 , N 2 and moisture increase. In addition, when incomplete combustion occurs due to a defect in the combustor, CO is generated.

Cool with air flowing outside. (4) is a suction port for taking in the air, and (5) is a discharge fan. The refrigerant cooled in this way expands in the expansion valve (6), so that the temperature further decreases, and is then guided to the indoor cooler (7). The indoor cooler (7) includes a suction filter (8),
It is equipped with an air cooling coil (9), a discharge fan (10), and a guide vane (11). The refrigerant guided to the indoor cooler (7) cools the indoor air with the air cooling coil (9), and then returns to the compressor (1) through return pipes (12) and (13). By performing this circulation continuously,

The air is supplied to one of the adsorption cylinders (25a) by the electromagnetic switching valve (24). The adsorption column is filled with activated alumina and synthetic zeolite that adsorb moisture in air, CO 2 , CO, and N 2 gas, and selectively adsorbs these gases with pressurization. The oxygen-enriched air is supplied to the outlet check valve (26
After passing through the discharge pipe (27) through a), the indoor cooler (7)
