Description

Total heat recovery ventilator with electrostatic precipitator

The present invention relates to a total heat exchange type ventilator equipped with an electrostatic precipitator, and more particularly, a pre-filter, ionizer, collector (component) of the precipitator inside the ventilator. Collector), a deodorizing filter, aerodynamic air supply or exhaust air in the building, apartments, houses, etc., and recovers the heat energy of the exhausted indoor air by electrothermal exchange method, bacteria contained in the external air introduced into the room The present invention relates to an electrothermal exchange ventilator equipped with an electrostatic precipitator that removes bacteria, exhaust gases, and maintains an appropriate indoor air temperature.

The air in an enclosed space gradually changes to carbon dioxide and contaminates over time, thereby inhibiting breathing. Therefore, a place where many people stay in a narrow space, such as an office or a vehicle, needs to be frequently ventilated. In this case, a ventilation system using an electrothermal exchange method is usually used. This is for supplying external air while maintaining the indoor air temperature, and for exhausting the indoor air.

4 and 6 show a configuration of a conventional total heat exchange type ventilator and a process of sucking outside air and supplying it to the room.

As shown in the related art, the total heat exchange ventilation device is provided with an external air suction hole so as to suck external air on one side of a main body case forming an external appearance.

The opening and closing device is provided around the external air suction hole to protect the heat exchanger from the outside, and a suction duct is formed between the heat exchanger and the external air sucked from the suction hole to reach the heat exchanger. It is formed to be a passage of external air.

On the other hand, in the conventional heat exchanger, each air having a temperature difference is caused to pass through different flow paths, and thus the heat exchanged sensible heat with moisture for exchanging latent heat by high-efficiency heat exchange membranes forming layers of the different flow paths. Follow the principle of electrothermal exchange.

The outside air through the heat exchanger from the outside air intake hole is supplied to the room by the outside air supply unit located at the other side of the intake hole and formed in the main body case.

The external air air supply unit is a duct installed at a predetermined height of the main body case to control the flow of air while supporting the motor and the air supply fan and the air supply fan rotated in accordance with the driving force to the motor, the air supply fan is supplied with power Consists of

As described above, the supply path to the interior of the outside air is

Outside-> Outside air intake-> Heat exchanger-> Outside air supply fan-> Outside air supply-> Indoor

Will be followed (see Figure 6).

On the other hand, in the total heat exchange type ventilator main body casing, the indoor air suction hole is formed on the other side of the external air suction hole so as to suck and exhaust the indoor air.

The indoor air sucked through the indoor air suction hole is exhausted through the heat exchanger like the external air in the external air suction hole described above, but according to the user's convenience, the indoor air can be directly discharged in the direction of the indoor air exhaust hole. A damper is provided in the indoor air suction hole duct.

Therefore, the exhaust path to the outside of the indoor air

Indoor-> Indoor Air Suction Hole-> Heat Exchanger-> Indoor Air Exhaust Fan-> Indoor Air Exhaust-> External Air

or

Indoor air-> Indoor air suction hole-> Bypass exhaust duct-> Indoor air exhaust fan-> Indoor air exhaust hole-> Outside air

Will be followed (see Figure 6).

As described above, since the conventional heat exchange type ventilation device described above is simply configured to exhaust indoor air and suck external air, the room is exposed to contaminated air.

Therefore, the conventional total heat exchange ventilation device has the following problems.

Since the conventional heat exchange type ventilation device includes only a pre-filter, bacteria, bacteria, exhaust gas, dust, and the like may be sucked into the heat exchanger, causing failure of the heat exchanger, and accumulating and accumulating for a long time. The contaminants may degrade the efficiency of the total heat exchanger and cause an increase in power costs.

In addition, since the conventional heat exchange type ventilation device is supplied to the room without bacteria, bacteria, exhaust gas, dust, etc. of the outside air being filtered out, there is a risk of harming the health of people in the room.

In addition, since the conventional heat exchanger does not have a built-in deodorization filter for removing the odor, if there is a bad smell in the vacuum air, people in the room may be exposed to the bad smell as it is unpleasant.

Accordingly, the present invention has been made to solve the above problems,

An object of the present invention is to provide an electrostatic precipitator between the external suction hole and the total heat exchanger, so that the external air can be supplied to the room as clean air while passing through the electrostatic precipitator and the total heat exchanger.

Another object of the present invention is to provide an air sucked from the outside through the electrostatic precipitator and the total heat exchanger to be supplied to the room as the air of a suitable temperature desired by the user.

Another object of the present invention is to recover the heat of the air discharged from the room, by reusing to maintain an appropriate temperature of the air supplied to the room, to maintain the optimal temperature and humidity of the room at low energy, can reduce the heating and cooling costs The purpose is to provide.
