Description

[0001] The present invention relates to a heat recovery type ventilation device having a dehumidification function,

The present invention relates to a heat recovery type ventilator capable of performing a dehumidification function so as to provide a heat recovery type ventilation function and a dehumidification function by integrally forming a dehumidification device by a thermoelectric element in a heat recovery type ventilator.

Generally, the building is provided with an air conditioner for cooling and heating indoor air.

Such an air conditioner directly exchanges outdoor air and indoor air, and therefore energy efficiency is degraded when the temperature difference between indoor and outdoor is large.

In order to compensate for this, a large number of heat recovery ventilators having a heat exchange element capable of minimizing the temperature difference between the indoor air and the outdoor air during the exchange of the indoor air and the outdoor air have been installed.

However, the conventional heat recovery ventilators do not have the function of dehumidifying the indoor air, only ventilating function of discharging indoor air and exchanging outdoor air with indoor air and then entering the room.

Therefore, conventionally, in order to dehumidify the room, a dehumidifying device has to be used separately. Recently, due to the phenomenon that the weather changes due to the global warming and the high temperature and high humidity, the dehumidifying device is increasingly used There is a trend.

In order to solve this problem, the Korean Intellectual Property Office (KIPO) No. 10-1361099 discloses that a vertically erectable enclosure is divided into a dry channel and a wet channel by vertical partition walls, and an air supply blower, an indirect evaporative cooler And a condenser, a heating coil, and an exhaust blower are installed in the wetting channel, a dehumidifying rotor is installed at a lower end of the vertical partition, an inlet port formed on the dry channel side of the housing, A cooler exhaust port and a first outside air inlet port, respectively, and an exhaust port and a second outside air inlet port are formed on the wet channel side of the housing, respectively; A first damper installed at an intake port of the dehumidifying cooling apparatus to open and close the intake port; A second damper installed in a duct connected to the exhaust port of the cooler of the dehumidifying cooling apparatus to open and close the exhaust port for the cooler; A third damper installed in a duct connected to the second outside air intake port of the dehumidifying cooling apparatus to open and close the second outside air intake port; A fourth damper provided in an intake duct branched from a duct connected to a second outside air intake port of the dehumidification cooling apparatus to draw in indoor air, the fourth damper being configured to intake or block indoor air into the second outside air intake port; And a controller for controlling the first to fourth dampers according to the operation mode set by the user to perform a cooling operation or a ventilation operation.

However, since the heating coil and the dehumidifying cooling device for cooling and heating are installed in the heat recovery type device, the cost and maintenance cost of the product itself are increased, which is not economical and the volume of the heat recovery type device becomes large, There is a problem in that it is difficult to install it.

According to the function of the heat recovery type ventilator 100 capable of dehumidification according to the present invention,

First, the present invention is characterized in that a heat recovery type ventilator which provides only a ventilating function for circulating indoor air through an exhaust flow path (A) and an air supply flow path (B) around a heat exchanging element is provided with a dehumidifying function, The humidity of the indoor air is removed to maintain a pleasant indoor air.

That is, the present invention can provide the ventilation mode and the dehumidification mode through the heat recovery type ventilator 100, and the ventilation mode and the dehumidification mode are divided according to whether the dehumidification unit 20 is operated or not.

5, the sliding door 32 of the sliding damper 30 is shut off between the ventilation portion 2 and the air supply portion 5 by the role of the partition wall, and the exhaust passage A ) And the air supply flow path (B) through the heat exchanging element (1) to ventilate the indoor air.

6, when moisture is sensed from the room air sucked by the humidity sensor 41 installed in the ventilation hole 2a, the dehumidifying unit 20 is operated by the automatic control of the control unit 40 At the same time, the sliding damper 30 is operated to open the space between the exhaust part 3 and the air supply part 5 to form an indoor air circulation passage C for recirculating only indoor air, .

Here, when the ventilation mode is operated, the air supply fan 8 simultaneously operates the exhaust fan 7 to forcedly circulate the indoor air. However, when the dehumidification mode is operated, the exhaust flow path A is shut off simultaneously with the operation of the dehumidifying unit 20 The air supply fan 8 is operated so that the exhaust fan 7 is stopped and the exhaust unit 2 and the air supply unit 5 are opened to forcefully recirculate the indoor air only through the indoor air circulating flow path C .

The operation of the sliding damper 30 is controlled by the sliding door 32 in which the rack 33a is meshed with the pinion 33b rotated by the driving motor 33c of the driving means 33 and the rack 33a is integrally formed. The exhaust passage A is blocked while blocking the ventilation surface of the heat exchange element 1 so that the exhaust passage A is blocked and the exhaust portion 2 The supply unit 5 can be opened.

Accordingly, the indoor air having moisture is sucked into the ventilation part 2 while the room air is recirculated through the indoor air circulation channel (C), and at the same time, the moisture is removed by the operation of the dehumidifying unit (20) 5 and the air supply mechanism 5a.

That is, when the electricity is inputted to the thermoelectric module 21, the operation of the dehumidifying unit 20 is such that the upper side where an exothermic reaction occurs is heated and the heat sink 23 is heated. Conversely, when the endothermic reaction of the thermoelectric module 21 occurs The heat absorbing and cooling part 22 on the lower side is cooled and formed in a cool air space in the space of the ventilation part 2 so that the indoor air having humidity is cooled in the process of passing through the ventilation part 2 22) and at the same time a condensation phenomenon (a phenomenon of water droplet formation at a dew point temperature due to a temperature difference) is generated, and water is condensed on the surface of the heat absorbing and cooling section 22 to be condensed to remove moisture in the air. The water agglomerated by the heat absorbing and cooling part 22 is naturally dropped into the water receiving part 26 provided at the lower part, collected and discharged at the same time.

The room air having passed through the heat absorbing / cooling unit 22 of the dehumidifying unit 20 is re-circulated back to the room in a state in which the moisture is removed, thereby providing a dehumidifying effect of lowering the humidity of the room.

Meanwhile, the present invention can selectively use the ventilation mode or the dehumidification mode by the control unit 40 irrespective of the moisture sensor 41.
