Description

Indoor Stand Type Total Heat Exchanger {A Ventilator}

The present invention relates to a total heat exchanger for purifying and ventilating indoor air, and more particularly, to a body comprising a lower inlet chamber through which indoor polluted air is introduced and an upper air supply chamber for supplying purified air, and is installed inside the body. A total heat exchange element and a lower chamber in which a filter for purifying polluted air is installed on the side surface of the body, a central chamber for discharging bets, and an upper chamber for discharging bets by bypass, and a stand type while supporting the body on the indoor wall It relates to an indoor stand-type total heat exchanger that further improves ventilation efficiency by installing the bet or outside air through a filter and ventilating it with electric heat, at the same time periodically backwashing the filter and discharging the bet air through a bypass without going through an electric heating element. will be.

In general, the air in a closed space provided inside a building has an increase in carbon dioxide content or is polluted over time due to the breathing or activity of the occupant, which greatly interferes with the resident's internal activity or health.

Therefore, in a large space or a narrow space where many people live, such as an office or a vehicle, it is necessary to frequently ventilate the polluted air inside to the fresh air outside. In this case, a ventilation device is commonly used.

Most of the conventionally known ventilation devices employ a method of forcibly discharging only indoor air to the outside using a blower. However, when only indoor air is forcibly exhausted using a blower, indoor cold or hot air is directly discharged to the outside without going through a separate filtering device, and outdoor air flows in through a door or window gap without heat exchange. The loss was so great that the cost of heating or cooling the room was unnecessarily high.

In addition, the sudden change in temperature of the indoor air due to sudden cold or hot inflow from the outside causes the people inside to feel uncomfortable. In addition to blocking the inflow of fresh air from the outside, oxygen deficiency may occur, and humidity control of the indoor air is not performed at all, and there is a problem that a comfortable indoor environment cannot be maintained even though a ventilation device is provided. .

In order to solve this conventional problem, a ventilation device of a total heat exchange method has been proposed that heat-exchanges the discharged indoor air first and then supplies outdoor air to the room when the indoor air is discharged to the outdoors.

The total heat exchange type ventilator as described above discharges indoor air to the outdoors and at the same time sucks in outdoor air and discharges it into the room. By allowing them to exchange heat with each other, the temperature of the outdoor air introduced into the room is adjusted so that it is close to the indoor air.

Accordingly, even when the room is ventilated by introducing the outdoor air into the room, the change in the room temperature is lowered, thereby minimizing an increase in the load required for cooling or heating.

Looking at the configuration of the ventilation device according to the total heat exchange method, a supply air duct for guiding outdoor air into the room is provided inside the hollow body, and it intersects the air supply duct at a predetermined position to guide the indoor air to the outdoors. An exhaust duct is provided. A total heat exchanger for exchanging heat between outdoor air supplied to and exhausted indoor air is provided at a point where the air supply duct and the exhaust duct intersect. At this time, the air supply duct and the exhaust duct are not interfered with each other by the partition wall dividing the interior of the body up and down.

As a related prior art, Korean Patent Registration No. 10-1272674 improves heat exchange efficiency when ventilating indoor and outdoor air.

However, the conventional ventilation device filters outdoor air with a pre-filter attached to the front end of the total heat exchanger and discharges it into the room, so the dust accumulated in the pre-filter needs to be cleaned or replaced periodically. It is very difficult and cumbersome to work because it has to go up and wash or exchange work. In particular, when the outdoor air is bad, the replacement or cleaning interval of the pre-filter becomes shorter, making maintenance more difficult.

In addition, in Registration No. 10-1819046, filed by the applicant of the present invention and registered publicly, the hollow duct body is divided by a bulkhead and a total heat exchanger is installed therein, so that heat exchange is performed while the exhausted indoor air and the incoming outdoor air intersect. At the same time, the air circulation control unit communicating with the filter device is installed on the front side of the total heat exchanger to ventilate the outdoor air in various modes depending on the quality of the outdoor air. A configuration using a filter device for cleanly ventilating a room so that each mode is switched is known.

However, the conventional electric heat ventilator as described above provides various functions. However, since ducts for outdoor air intake and indoor air exhaust are installed on the ceiling and buried so that indoor air can be ventilated through them, one room or individual office space There is a problem that installation is difficult.

In addition, since the conventional electric heat ventilator is installed inside the ceiling, the ceiling of an aged building or school is made of a material fatal to health, such as asbestos, and there is a problem that health and environmental problems may occur to remove and install them.
