CLEANING AND AIR CONDITIONING SYSTEM OF CIRCULATING AIR

摘要

A circulating air-conditioning device is provided to use of a filter unit for a long time by being installed in the front of the filter unit and removing harmful gas, and to have compact construction by needing no spray device and space for allowing absorption liquid to be evenly sprayed. A circulating air-conditioning device absorbing and processing harmful gas in indoor circulating air comprises a case(51), a forced circulating unit(65), an absorption device(70) and a filter unit(57). The forced circulating unit forcibly circulates air through the case. The absorption device absorbs the harmful gas contained in the circulating air through the case by circulating absorption liquid. The filter unit is formed in the rear of the absorption device.
