Benefits of technology

The present invention is a ventilating system that aims to overcome the limitations and disadvantages of existing ventilating systems. The system has a small size and includes a fan unit with two fans that can draw air from both the inside and outside of a room. The system also includes a heat exchanger for heating the air being drawn into the room and a bypass flow passage for bypassing the heat exchanger. The system has a simple structure and is easy to install. The technical effects of the invention include improved air circulation, reduced flow resistance, and efficient heat exchange.

Problems solved by technology

Air in a closed room is gradually polluted as time passes-by due to respiration of people in the room.
Accordingly, an adequate space is required for installation of the ventilating system, to require a great height between floors of adjacent flats, i.e., a flat height, which impairs spatial efficiency and economy of a building.
However, the pre-heat exchanger can not but make the case of the ventilating system larger.

Embodiment Construction

[0044] Reference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts.

[0045]FIGS. 1 and 2 illustrate perspective views of ventilating systems in accordance with a preferred embodiment of the present invention. FIG. 1 illustrates a state an upper portion of a body is opened for the sake of description.

[0046] Referring to FIGS. 1 and 2, the ventilating system includes a case 100 and a fan unit. The case 100 has a box shape with an inside space.

[0047] It is preferable that the case 100 is attached to a ceiling of a room, and preferably, has a small height h0 and a large width for reducing a ceiling height required for installation of the case 100.

[0048] The case 100 has a first flow passage 110 for guiding outdoor air to the room, and a second flow passage for guiding room a...

Abstract

The present invention relates to ventilating systems, and more particularly, to a ventilating system having a heat exchanger for exchanging heat of room air being discharged to an outside of a room with heat of outdoor air supplied to the room. The present invention provides a ventilating system including a case having a first flow passage for guiding outdoor air to a room, and a second flow passage for guiding room air to an outside of the room, and a fan unit in the case, the fan unit having a first side for drawing the outdoor air from the first flow passage, a second side for drawing the room air, and a circumferential side for discharging the outdoor air drawn through the first side to the room, and discharging the room air drawn through the second side to an outside of the room.

Description

CROSS-REFERENCE TO RELATED APPLICATION [0001] This application claims the benefit of Korean Application No. P2005-0014457 filed on Feb. 22, 2005, which is hereby incorporated by reference as if fully set forth herein. BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention relates to ventilating systems, and more particularly, to a ventilating system having a heat exchanger for exchanging heat of room air being discharged to an outside of a room with heat of outdoor air supplied to the room. [0004] 2. Discussion of the Related Art [0005] Air in a closed room is gradually polluted as time passes-by due to respiration of people in the room. Therefore, it is required to replace the polluted room air with fresh outdoor air, for which the ventilating system is provided. [0006] In general, the ventilating system is installed in a ceiling in the room. Accordingly, an adequate space is required for installation of the ventilating system, to require a great ...
