Description

A heat exchanger equipped with a large-capacity filter through which air flows to the side {A Ventilator}

The present invention relates to a total heat exchanger for ventilating indoor air, and more specifically, an air heat exchange chamber provided with a heat exchange element, a filter part provided under the heat exchange part, and an air flow chamber provided to allow air to flow in the side surfaces thereof. It consists of a part, the filter part is provided with a lower chamber and an upper chamber, and the heat exchange part and the filter part are separately operated, and a large-capacity filter unit is provided between the upper chamber and the lower chamber, so that the capacity of the filter can be enlarged. At the same time, by allowing the filter to be mounted and detached in the lateral direction, it is possible to improve the ventilation performance of the heat exchanger as well as to facilitate the replacement of the filter, so that the ventilation efficiency and the convenience of operation are dramatically improved, and the heat transfer with a large-capacity filter through which air flows It is about the exchange.

In general, the air in an enclosed activity space provided inside the building increases or becomes contaminated with carbon dioxide over time due to the inhabitants 'breathing or activity, which has many harmful effects on the inhabitants' internal activities or health.

Therefore, when a person stays in a confined space such as an enclosed space such as an office, the contaminated air in the interior space must be replaced with fresh air from outside to be ventilated from time to time. At this time, a ventilation device is commonly used.

Most of the ventilation devices known in the prior art employ a method of forcibly discharging only indoor air to the outside using a single blower fan. However, when only the indoor air is forcibly discharged using a single blower fan, the indoor cold air or heat is discharged to the outside without filtration, and the outdoor air is heated without heat exchange through a door or window opening. The cost of cooling has become unnecessary.

In addition, due to the sudden change in temperature of the indoor air due to sudden cold and heat flowing from the outside to the inside, people in the interior feel uncomfortable, and in particular, when only indoor air is discharged outside when a window or door frame in the room is closed. In addition, the inflow of fresh air from the outside may be blocked, and oxygen deficiency may occur. In addition, the humidity of indoor air is not controlled at all, and there is a problem in that a comfortable indoor environment cannot be maintained despite the ventilation system. .

In order to solve this conventional problem, when exhausting indoor air to the outside, a ventilation device of a total heat exchange method for first exchanging the exhausted indoor air with heat and then supplying the outdoor air to the room has been proposed.

In the process of exhausting indoor air to the outside and ventilating outdoor air and discharging it indoors, the heat exchanger of the above-described heat exchange method exchanges them with each other by exchanging heat between indoor air discharged outdoors and outdoor air flowing into the room. In this case, the temperature of the outdoor air flowing into the room is increased to supply air to the room air.

Accordingly, even if the indoor air is introduced and ventilated by outdoor air, a change in the indoor temperature can be lowered, thereby minimizing an increase in load required for cooling or heating.

Looking at the general configuration of the general heat exchange type ventilation system, the inside of the hollow body is provided with an air supply duct that guides outdoor air into the room, and an exhaust duct that crosses the air supply duct at a predetermined position and guides indoor air to the outdoors. Is provided. In addition, an electric heat exchanger is provided for exchanging outdoor air that is supplied with air and indoor air that is exhausted at a point where the air supply duct and the exhaust duct intersect. At this time, the air supply duct and the exhaust duct do not interfere with each other by partition walls partitioning the inside of the body up and down.

As related prior arts, Patent Nos. 10-1272674 and 10-2008-0024379 discloses uniform indoor and outdoor air flow to improve heat exchange efficiency.

However, since the conventional heat exchanger is installed and operated on the ceiling, there is a problem that it is very difficult and difficult to replace and mount a filter (pre-filter) provided in the heat exchange element due to the limited space.

In addition, since the filter provided in the conventional heat exchanger is installed in the external air supply unit of the soft exchange element, there is a limitation that the size (capacity) of the filter cannot be increased due to the installation space limitation.
