The present invention relates to a combined-use window type air conditioner, and more particularly, to a combined-use window type air conditioner consisting of an air conditioner and a ventilation device.

In general, the air conditioner is to cool or heat the indoor air in conjunction with the refrigeration cycle while circulating the air, the configuration is largely divided into indoor and outdoor units. The indoor unit and the outdoor unit are installed in one body and are called an integrated air conditioner, and each separately installed is called a separate type air conditioner.

The representative of the former integrated air conditioner is the window type air conditioner, the latter of the separate type air conditioner is the ceiling type and package type.

The air conditioner is composed of a compressor for raising / heating a low / low pressure gas refrigerant to a high / high pressure gas refrigerant, a condenser for condensing the refrigerant introduced from the compressor by outside air, and a narrow diameter compared to the diameter of other parts. An expansion valve for reducing the refrigerant introduced from the condenser, and an evaporator for absorbing heat in the refrigerator as the refrigerant passing through the expansion valve in a low pressure state as a basic component.

Therefore, the air conditioner is to cool or heat the room by the endothermic action of the evaporator and the heat dissipation action of the condenser while the refrigerant circulates the refrigeration cycle.

On the other hand, while the air conditioner is in use, the interior is sealed to maintain a cooling or heating environment.

As such, the air in the enclosed space increases the carbon dioxide content over time due to the breathing of the living organisms, which interferes with the breathing of the living creatures. Therefore, when a large number of people stay in a small space such as an office or a school, it is often necessary to replace the indoor air with fresh air. At this time, a commonly used ventilation device.

Most conventional ventilation apparatuses employ a method of forcibly discharging only indoor air to the outside using a single blower. However, when forcibly discharging only the indoor air by using one blower, the indoor air is discharged to the outside without filtration and the outdoor air is introduced without heat exchange through a door or window gap, thereby heating and cooling the room. Cooling costs unnecessary.

In addition, due to the sudden inflow of cold air and heat from the outside, the sudden change in the temperature of the indoor air makes people feel uncomfortable, and in particular, only indoor air is discharged to the outside when the windows and doors are closed. In this case, the inflow of external fresh air may be blocked and oxygen deficiency may occur, and there is a problem in that the indoor air humidity is not controlled at all and thus does not maintain a comfortable indoor environment.

In order to solve this problem, a total heat exchange type ventilation apparatus for exchanging outdoor air and indoor air first and then supplying the indoor air has been proposed.

At this time, the outdoor air (a2) passing through the heat exchanger (3) is supplied to the air supply processing device (6) mounted on the lower part of the indoor unit (5) along the branched air supply duct (21).

On the other hand, indoor polluted air is sucked in and reaches the total heat exchanger (3) through the exhaust duct (2), and is sucked through the air supply duct (11) and passes through the total heat exchanger (3) to outdoor after heat exchange. Discharged.

Hereinafter, the configuration of the total heat exchanger 3 and the heat exchange process between the outdoor air and the indoor air in the heat exchanger 3 will be described with reference to FIG. 3.

Referring to FIG. 3, an air supply flow path 23 through which outdoor air is guided indoors is provided inside a box-type electrothermal heat exchange element 31. A guided exhaust passage 13 is provided. In addition, an electric heat exchanger 32 is provided to exchange heat between the outdoor air that is supplied at the point where the air supply passage 23 and the exhaust passage 13 intersect and the indoor air that is exhausted.

At this time, the air supply passage 23 and the exhaust passage 13 do not interfere with each other while traversing the internal space of the heat exchange element 31 up and down, respectively, around the heat exchange unit 32. This is possible by the partition (not shown) which divides the said air supply flow path 23 and the exhaust flow path 13 up and down.

On the other hand, an air supply fan 25 for forcibly sucking outdoor air is provided on the air supply outlet side of the air supply passage 23, and the air inlet and the heat exchanger 3 of the air supply passage 23 are included in various types of outdoor air.

In addition, an exhaust fan 15 for forcibly discharging indoor air is provided at an exhaust outlet side of the exhaust passage 13.

On the other hand, the heat exchange element 31 has a hexahedral shape, the upper and lower edges are supported by the case and the left and right edges are supported by the partition wall separating the air supply duct 21 and the exhaust duct 11, the air supply passage ( 23 and the exhaust passage 13 are formed independently, and a heat exchange membrane having excellent heat conduction efficiency is provided at the boundary between the air supply passage 23 and the exhaust passage 13.

The heat exchange action in the heat exchanger configured as described above is performed by the sensible heat exchange between the supplied outdoor air and the exhausted indoor air, and the hot air in the indoor or outdoor air is below the dew point temp. It is made of latent heat exchange by the condensate produced in the state of.

In the case of the electrothermal exchange ventilator as described above, the outdoor air supplied when the room is in a cooling or heating atmosphere is primarily heat-exchanged with the indoor air and then introduced into the room, thereby preventing a sudden increase or decrease in the room temperature. In addition, the air conditioning load can be reduced to save energy.

However, the air supply direct ventilation type air conditioning system of the above-described type is provided with an exhaust port installed in the ceiling of the room, and the installation work is complicated by the installation of the exhaust port and the exhaust duct, which increases the installation cost as the length of the duct becomes longer. An increasing problem arises.
