Description

Heat recovery ventilation device to remove ultra fine dust and virus

The present invention relates to a heat recovery ventilation device that removes ultrafine dust and viruses, and more particularly, collects charged ultrafine dust and removes harmful microorganisms such as viruses and bacteria in the air. It relates to a heat recovery type ventilation system to be removed.

In general, a heat recovery type ventilation device supplies cold/hot air to a room using the heat exchange principle using a heat storage catalyst. It was possible to perform both the heat exchange function and the ventilation function at the same time or one function alone.

In such a conventional ventilation device, an air purification filter is installed to remove fine dust from polluted air containing fine dust (or fine particles) either indoors or outdoors through which a motor and a fan for air purification flow into the ventilation device.

However, the air purification filter is contaminated by adsorption of fine dust as the process of collecting fine dust is repeated, that is, the process of adsorption and dust collection is repeatedly performed as fine dust is adsorbed (or adhered) from the passing polluted air. The fine dust collection efficiency gradually decreased, and as the fine dust collection efficiency fell, it caused respiratory health problems for users of the ventilation system.

Referring to FIG. 11 , the dust collecting unit 300 is installed at the rear end of the electric charge unit 200 among the conduits of the ventilation body 110 in order to collect the ultrafine dust charged in the electric charge unit 200 .

The dust collecting unit 300 may collect ultra-fine dust by electrostatic force by a filter or an electric dust collecting method.

In this case, when the dust collecting unit 300 is implemented as a dust collecting filter, it may be installed at the rear end of the electric charge unit 200 by having a plurality of layers in order to maximize the dust collecting efficiency of the charged ultrafine dust.

In addition, the dust collecting filter may be formed with spiral or protruding protrusions on the fibers of the dust collecting filter and the outer periphery of the fibers of the dust collecting filter. Through this, the contact area between the air containing the charged ultrafine dust and the dust collecting filter may be increased.

Furthermore, although the dust collecting unit 300 is not shown in the drawing, it may be possible to hold the dust collecting filter with a gap adjusting device having the same configuration as the gap adjusting device 220 , and the lower layer having the same configuration as the lower diaphragm 230 .

Referring to FIG. 11 , the heat exchange unit 400 is installed at the rear end of the dust collecting unit 300 among the pipes of the ventilation body 110 in order to exchange heat with the air in which the ultrafine dust has been collected.

In addition, the heat exchange unit 400 ^{can exhibit, for example, a thermal efficiency of 87% of 80 m 3} per hour, and as it has a shorter air movement path than the polyethylene heat exchanger, the thickness of the unit is kept thinner than that of the polyethylene heat exchanger. It is possible to do it, while the consumption of energy and the noise can be low.

Referring to FIG. 11 , the TVOC removal catalytic filter 500 is installed at the rear end of the heat exchange unit 400 in the pipeline of the ventilation body 110 to remove TVOC (total volatile organic compounds) from the heat-exchanged air.

Since the TVOC removal catalyst filter 500 has the same configuration as a typical TVOC removal catalyst filter, a detailed description thereof will be omitted.

11 to 12, the ultrasonic generating means 600 is a TVOC removal catalytic filter (TVOC removal catalyst filter) It is installed at the rear end of the 500), and is configured to include an ultrasonic control unit 610, a signal amplifying unit 620 and a transducer (630).

The ultrasonic controller 610 may be configured as, for example, a function generator, and the function generator may serve to adjust a frequency magnitude, determine a waveform of a frequency, and adjust a voltage.

The ultrasonic control unit 610 controls the waveform of the frequency to generate ultrasonic waves of 20,000 Hz or more, and if necessary, to generate ultrasonic waves having a predetermined frequency in a set frequency range or to generate periodically variable ultrasonic waves. can

As such, the signal output from the function generator is a value of a low voltage state, is amplified by a power amplifier, which is the signal amplifier 620 , to increase the voltage, and is converted into ultrasonic waves through the transducer 630 to TVOC It is transferred to the removal catalyst filter (500).

Through this ultrasonic wave, harmful microorganisms including viruses or bacteria collected in the TVOC removal catalytic filter 500 are removed.

The transducer 630 is installed at the rear end of the TVOC removal catalyst filter 500 based on the moving direction of the air, and is spaced apart from the TVOC removal catalyst filter 500 by a predetermined distance. In this case, the intensity of the ultrasonic wave output from the transducer 630 may be controlled differently according to the distance between the transducer 630 and the TVOC removal catalyst filter 500 .

As a specific example, when the distance between the transducer 630 and the TVOC removal catalytic filter 500 is relatively long, the intensity of ultrasonic waves is increased, and on the contrary, between the transducer 630 and the TVOC removal catalytic filter 500 . When the distance is relatively close, the intensity of the ultrasonic wave may be reduced. This increases the intensity of ultrasonic waves in proportion to the distance between the transducer 630 and the TVOC removal catalytic filter 500 or increases the intensity of the ultrasonic waves in proportion to the distance between the transducer 630 and the TVOC removal catalytic filter 500 . It is possible to prevent a decrease in the removal efficiency of harmful microorganisms according to the distance.

In addition, the transducer 630 may be disposed in the conduit of the ventilation body 110 to output ultrasonic waves in a direction transverse to the air movement direction in order not to obstruct the flow of air.
