摘要:
The present invention discloses an improved air conditioning system which can supply fresh air prepared separately. A first preferred embodiment of the present invention provides an air conditioning system including an outdoor unit, an indoor unit installed in a ceiling, and means connected to the indoor unit for supplying fresh air stored separately to the indoor unit. A second preferred embodiment of the present invention provides an air conditioning system including an outdoor unit, an indoor unit, air supply and air discharge ducts, and means connected to the air supply duct for supplying fresh air stored separately to the indoor unit. In the second embodiment, the indoor unit includes a fan, an indoor heat exchanger, and a guide duct for guiding flow passages of the external air and room air, and, if necessary, further including a preheat exchanger arranged to surround the guide duct for indirect heat exchange between the external air and the indoor air.

A method for controlling flow rates of outdoor air supplied to a room and room air discharged to an outside of the room in ventilation. The method of the present invention includes the steps of supplying outdoor air drawn through an air supply duct to a room at a first flow rate, and discharging room air drawn through an air discharge duct to an outside of the room at a second flow rate higher than the first flow rate. The first and second flow rates vary with rotation speeds of fans respectively mounted on an air supply duct and an air discharge duct.

A surface discharge type air cleaning device including an insulating dielectric body formed in the shape of a sheet, a discharge electrode formed at the upper surface of the insulating dielectric body, and a ground electrode formed at the lower surface of the insulating dielectric body. The discharge electrode is formed of a closed pattern having a predetermined area on the upper surface of the insulating dielectric body. The discharge electrode has a non-pattern part disposed in a pattern part where the pattern is formed. The electrode is not formed at the non-pattern part. The ground electrode is formed at a predetermined position corresponding to the non-pattern part. The area of the non-pattern part is reduced to decrease generation of ozone, and the area of the pattern part is enlarged to increase generation of negative ions and hydroxyl radicals. Consequently, the number of negative ions and hydroxyl radicals is increased while the amount of ozone is decreased, and therefore, air cleaning efficiency is improved.

A compact ventilating system having an air purifying function is disclosed, which includes a case having one end buried in a ceiling of a room, and the other end projected toward the inside of the room; an air-supplying passage of communicating the outside of the room, the case, and the inside of the room with one another, to supply an outdoor air to the inside of the room; an air-discharging passage of communicating the inside of the room, the case, and the outside of the room with one another, to discharge an indoor air to the outside of the room; an air-circulating passage of communicating the inside of the room with one point of the air-supplying passage inside the case, to introduce the indoor air to the case, and to re-supply the air to the inside of the room; and a fan provided in the case, for supplying the outdoor air introduced to the case through the air-supplying passage to the inside of the room, or re-supplying the indoor air introduced to the case through the air-circulating passage to the inside of the room.
摘要:
A surface discharge type air cleaning device comprises an insulating dielectric body formed in the shape of a sheet, a discharge electrode having a pattern part of a predetermined area formed on the upper surface of the insulating dielectric body and at least one non-pattern part disposed in the pattern part and a ground electrode formed at the lower surface of the insulating dielectric body. The discharge electrode and the ground electrode have a plurality of pointed ends protruded therefrom, respectively. The pointed ends of the discharge electrode and the pointed ends of the ground electrode are disposed at the upper and lower surfaces of the insulating dielectric body, respectively, such that the pointed ends of the discharge electrode and the pointed ends of the ground electrode correspond to each other. Generation of negative ions and hydroxyl radicals is increased while generation of ozone is decreased, and therefore, air cleaning efficiency is improved.

The present invention provides an air conditioning system including an outdoor unit, an indoor unit, and air supply and air discharge duct. The outdoor unit includes a compressor and an outdoor heat exchanger, and the indoor unit in a ceiling includes an indoor heat exchanger, a fan, guide means, and a preheat exchanger. The indoor heat exchanger has a space therein in communication with a room, and the fan is in the space for drawing air and discharging through the indoor heat exchanger. The guide means is provided on an underside of the indoor heat exchanger, for guiding the external air to the room through the fan, and the room air to an outside of the room. The preheat exchanger is arranged adjacent to, and in communication with the guide means, for indirect heat exchange of the external air and room air passing therethrough. The air supply duct and the air discharge duct are respectively connected to the preheat exchanger, for guiding the external air to the room, and the room air to the outside of the room.
