  • Fig. 1 is a perspective view of a configuration of an indoor equipment of an air conditioner according to the present invention.
  • Fig. 2 is a cross-section of an internal configuration of the indoor equipment.
  • an indoor equipment 1 of the air conditioner includes a first intake 18 to take air in a room therein, and an indoor heat exchangers 2, 4, and 12 to cool or heat the air in the room that has been taken therein through the first intake 18.
  • the indoor equipment 1 further includes an outlet 10 to return the air that is heat-exchanged by the heat exchangers 2, 4, and 12 in the room, a fan 15 to take air in through the first intake 18 and to blow out the heat-exchanged air to the room from the outlet 10, a gas adsorption filter 11 that is arranged at a position between the indoor heat exchanger 12 and the first intake 18 and near the indoor heat exchanger 12 on an upper stream side in an air flow path, a ventilator 13 that is arranged on one side of the indoor equipment 1, and a prefilter 3 that is arranged inside the indoor equipment 1 from a front part toward an upper part, and that removes impurities such as dust and dirt from the air that is led to the indoor heat exchangers 12, 2, and 4 through the first intake 18, as main components. Because the first intake 18, the indoor heat exchangers 12, 2, and 4, the outlet 10, the fan 15, and the prefilter 3 are well-known techniques, the explanations thereof are omitted herein.
  • Fig. 3 is a front view of a configuration of the ventilator.
  • an opening 9 is formed long in the horizontal direction above the gas adsorption filter 11, and the ventilator 13 includes a duct 20 having a discharge fan 5 at an end.
  • the discharge fan 5 communicates on a downstream side thereof with air outside the room in which the indoor equipment 1 is installed.
  • the ventilator 13 functions as a discharge mechanism that discharges atmosphere inside the indoor equipment 1 of the air conditioner to the outside.
  • the gas adsorption filter 11 is held in a case (frame) as a holder, and has a function of absorbing and removing harmful substances such as a foul odor component and VOC included in air taken. It is not necessary to particularly limit the arrangement of the ventilator 13 from the point of view of the discharge of atmosphere inside the indoor equipment 1 to the outside. However, it is preferable that the opening 9 be arranged at a position at least higher than the gas adsorption filter 11 so that ascending gas molecules that have been desorbed from the gas adsorption filter 11 are efficiently discharged, from the view point of bearing a part of a filter regenerating function.
  • the heat exchangers 12, 2, and 4 are used as heat sources that conduct heat to the gas adsorption filter 11. Therefore, as well as being arranged on the inside of the first intake 18 for the function thereof, the gas adsorption filter 11 is preferably arranged as close to the heat exchangers 12, 2 and 4 as possible.
  • louver 19 of the outlet 10 Prior to bringing the heat exchangers 12, 2 and 4 to high temperatures by means of the heat sources, a louver 19 of the outlet 10 is closed, and the fan 15 is run at a low speed.
  • the louver 19 is not necessarily be required to be closed, it is preferable that the louver 19 be closed to prevent the gas component desorbed and concentrated in the indoor equipment 1 from leaking, and to perform the discharge of the gas components efficiently by enhancing the hermeticity inside the indoor equipment 1 to make the pressure inside the indoor equipment negative.
  • the fan 15 be run to exchange heat to some extent to prevent failure of the air conditioning system because if very little heat exchange is executed when the heat exchangers 12, 2, and 4 are set to high temperatures, a large quantity of a liquid-phase refrigerant flows into an expansion valve, and thus there is a possibility of causing malfunction such as abnormal noise.
  • the output of the fan 15 be the minimum output within an allowable range of a refrigerant system load of the air conditioner.
  • a refrigerant gas at a high temperature is fed to the heat exchangers 12, 2, and 4, and the heat exchangers 12, 2, and 4 are heated to high temperatures, for example, a temperature about 70C° ⁇ 10C°, within an allowable range for control of a compressor (not shown) and the expansion valve included in the air conditioner.
  • gas adsorption filter 11 gas components that have been adsorbed are desorbed, thereby regenerating the gas adsorption filter 11.
  • the effect can be obtained even with a temperature that can normally be set to the indoor equipment 1 with a remote control or the like as a filter regeneration temperature.
  • the temperature is set to the highest temperature allowable as an air conditioning system, more gas molecules are likely to be desorbed from the gas adsorption filter, and therefore it is preferable.
  • Fig. 8 is a flowchart of a specific filter regeneration control.
  • the air conditioner is started (Step S101), and then stopped (Step S102).
  • a total operating time since last filter regeneration control is checked, in most cases, by means of a timer integrated in a computer program that is executed on a computer of a control device. It is then determined whether the total time has exceeded a predetermined time, for example, 125 hours (Step S103). If not exceeded, it is determined that the regeneration control is not necessary, and the control is ended.
  • a predetermined time for example, 125 hours
  • Step S104 When the total time has exceeded the predetermined time, the fan of the indoor equipment is rotated at a slow speed, and a discharge fan of the ventilator is run (Step S104). Thereafter, a heating-up control is executed to heat the heat exchangers to high temperatures (Step S105). If possible, a temperature inside the indoor equipment and the duration of the filter regeneration control are measured (Step S106). When the duration has exceeded a predetermined time, for example, 1 hour, it is determined that sufficient filter regeneration has been performed, to end the control. When the filter regeneration is to be executed forcibly irrespective of the total operating time since the last filter regeneration control, a mode for forcibly executing the filter regeneration can be set independently from the flow of the control (Step S107).
  • the filter regeneration control can be executable by adding the procedure above mentioned to a computer program for a control computer that is usually included in an air conditioner.
  • a filter regeneration function for a gas adsorption filter can be given to an air conditioner having a ventilator, without changing the configuration thereof.

Moreover, a damper (rotating opening/shutting door) 21 is arranged in the second intake 7. When the damper 21 is open, air is taken also through the second intake 7, which is formed when the damper 21 is open, and a function as a normal ventilator in which pressure drop is low and that can exhaust air in large volume is obtained. When the damper 21 is closed, to efficiently discharge gas molecules that are desorbed from the gas adsorption filter 11 and concentrated inside the indoor equipment 1, air is taken through an opening 22 that is arranged above the gas adsorption filter 11.
  • the gas adsorption filter 11 when the gas adsorption filter 11 is arranged between the second intake 7 and the discharge fan 5, a strong flow of air is generated between the second intake 7 and the discharge fan 5, and as a result, the desorbed gas components can be discharged efficiently.
  • the second intake 7 is arranged to generate such an air flow.
  • a heater is used as a heat source to conduct heat to the gas adsorption filter 11.
  • various heaters are placed on a filter holder 31.
  • an electrically-heated wire (resistance wire) 34 such as a nichrome wire and a canthal wire is run throughout a surface of a filter holder 33.
  • another type of heater such as a PTC (positive temperature coefficient) heater, and an elastomer heater can be attached on the filter holder 33.
  • the gas adsorption filter 11 is directly heated up, and gas components can be desorbed efficiently.
  • a heater is arranged on the filter holder 31 or 33 as a heat source to regenerate the gas adsorption filter 11
  • the filter holder 31 or 33 which are conventionally arranged, with a heater
  • a large-scale structure is not required, and the cost therefore can also be low.
  • this arrangement does not increase airflow resistance of the gas adsorption filter 11, the need for design modification (upsizing of a fan or a motor) associated with this arrangement can be eliminated.
  • the heater can be used together with the heated heat exchangers 12, 2, and 4.
  • the gas adsorption filter 11 can take various forms such as a sheet form, a pleats form, a honeycomb form, and a corrugated form.
  • materials of the filter using a synthetic fiber such as polypropylene, polyester, and a polyamide-containing synthetic fiber, or a natural fiber such as cellulose and rayon as a base, one that carries thereon an adsorbent such as activated carbon and zeolite, one itself having a high adsorption effect such as an activated carbon fiber and polyacrylic acid, or one formed by directly shaping an inorganic porous material of clay mineral such as cordierite and sepiolite into the above forms can be used. It is preferable that the material have a property that at least odorous components are desorbed when heat of a heat source is applied. It is because removal of odorous components is the foremost requirement for the gas adsorption filter 11.
  • the air conditioner and the filter regeneration control method for the air conditioner according to the present invention are useful as an air conditioner including a discharge mechanism that discharges atmosphere inside the indoor equipment of the air conditioner to outside of a room in which the indoor equipment is installed, and useful for control thereof.
