Description

Window type heat exchange ventilator

The present invention relates to a window-type heat exchange ventilator that is installed on a window to ventilate indoor and outdoor air while minimizing indoor thermal energy loss.

In general, various types of ventilation devices have been used to discharge turbid indoor air to the outside and supply fresh outdoor air to the room. Meanwhile, in the season when the temperature difference between indoor and outdoor is large, such as summer and winter, cooling and heating are operated to maintain a comfortable temperature of the indoor space. This lowers the energy consumption.

In order to reduce this problem even a little, a so-called heat exchange ventilator is used that allows outdoor air to exchange heat with the discharged indoor air before it is introduced into the room, thereby reducing a factor of increasing the heating and cooling load due to a temperature difference.

Such a heat exchange ventilator is mainly installed on the ceiling of an indoor space by a duct method. For this purpose, since the duct facility needs to be installed through the outer and inner walls of the building, there is a problem in that the construction work is cumbersome and the construction cost is burdened.

An object of the present invention is to provide a window-type heat exchange ventilator that can improve the convenience of installation work and reduce the burden of installation costs.

A window-type heat exchange ventilator according to the present invention for achieving the above object includes a case, an outdoor grill, an indoor grill, a blower for outdoor air, a blower for betting, a heat exchanger, filters, a bypass damper, and Includes a recirculation damper. The case is provided with an outdoor air intake port and an indoor air exhaust port on the left and right on the outdoor side, and an outdoor air exhaust port and an indoor air intake port are provided on the left and right respectively close to the outdoor air intake port and the indoor air exhaust port on the indoor side. A flow path and a bypass betting flow path are formed. The outdoor grill is formed with an outdoor air inlet communicating with the outdoor air intake port, and a betting outlet communicating with the outdoor air outlet port, and is mounted on the outdoor side of the case. The indoor grill is formed with an outdoor air outlet communicating with the outdoor air outlet port and a bet suction port communicating with the bet suction port, and is mounted on the indoor side of the case. The blower for outdoor air is disposed in the case adjacent to the outdoor air intake port and the outdoor air discharge port to send out the outdoor air. The bet blower is disposed in the case adjacent to the bet suction port and the bet discharge port to send out the bet. The heat exchanger is disposed in the case to exchange heat between the outside air flowing through the outdoor air flow path and the outside air flowing through the main bet flow path. The filters purify the inside and outside air flowing through the outside air flow path and the main air flow path. The bypass damper opens and closes the bypass betting flow path. The recirculation damper selectively communicates the main bet flow path with the outside air flow path at the inlet end side of the heat exchanger.

Since the window-type heat exchange ventilator according to the present invention is structurally slim and easy to install on the windows, it is possible to increase the convenience of installation work and reduce the burden of installation costs compared to the existing duct method. The window-type heat exchange ventilator according to the present invention can properly implement a general ventilation mode, a bypass ventilation mode, and a recirculation mode depending on the temperature or the degree of outdoor air pollution, thereby maintaining a comfortable indoor environment.

The bypass bet flow path 113 may be disposed close to the bet suction port RA and branch from the main bet flow path 112 . Therefore, in the bypass ventilation mode, all bets may be discharged to the outdoors through the bypass betting flow path 113 by the blower 150 for betting.

The outdoor grill 120 has an outdoor air intake 122a communicated with the outdoor air intake port OA, and a bet discharge port 122b formed with an outdoor air intake port EA to communicate with the outside air intake port OA, and is mounted on the outdoor side of the case 110. The outdoor grill 120 sucks the outside air through the outside air intake port 122a and delivers it to the outside air intake port OA, and delivers the bet discharged from the outside air exhaust port EA to the bet discharge port 122b to discharge it. The outdoor grill 120 blocks between the outside air intake port OA and the inside exhaust port EA, so that the inside and outside air do not mix.

For example, the outdoor grill 120 may include a roof member 121 and a grill member 122 . The inner space of the roof member 121 is partitioned by the partition wall 121a disposed between the outside air intake port OA and the inside exhaust port EA.

The roof member 121 has a convexly curved upper portion extending outwardly and an open lower portion. The roof member 121 may extend outwardly while the left and right portions are convexly curved. Accordingly, the roof member 121 can block the inflow of rainwater into the outdoor air intake 122a and the bet discharge port 122b of the grill member 122 while flowing rainwater well while exposed to the outdoors.

The grill member 122 is mounted on the lower opening of the roof member 121 in a form in which the outdoor air inlet 122a and the bet outlet 122b are formed on the left and right edges and the central portion is blocked. The grill member 122 may be formed in a form in which the left and right edge portions having the outdoor air intake port 122a and the bet discharge port 122b are inclined outward from the inside of the roof member 121 toward the top. Therefore, the grill member 122 can increase the effect of blocking the inflow of rainwater to the outdoor air intake (122a) and the bet outlet (122b).

The indoor grill 130 has an outdoor air outlet (131a) communicating with the outdoor air outlet port (SA), and a bet suction port (131b) communicating with the inner air intake port (RA), and is mounted on the indoor side of the case (110).

The outdoor air is sucked into the outdoor air flow path 111 by the outdoor air blower 140 from the outside, and is discharged into the room through the outdoor air filter 171 and the heat exchanger 160 . In this process, the outdoor air may be heat-exchanged with the bet by the heat exchanger 160 in a state of being purified by the outdoor air filter 171 to be supplied to the room. As a result, the room can be ventilated.

As shown in FIG. 5 , in the bypass ventilation mode, the bypass betting flow path 113 is opened by the bypass damper 180 , and the outdoor air intake port OA is opened by the damper. The main bet flow path 112 may be blocked from the outside air flow path 111 by the recirculation damper 190 .

In this state, the bet is sucked into the bypass bet flow path 113 by the blower 150 for betting from the room and discharged to the outside. The outdoor air may be sucked into the outdoor air passage 111 by the outdoor air blower 140 from the outside, purified by the outdoor air filter 171 , and then supplied to the indoor without heat exchange with the bet in the heat exchanger 160 .

As shown in FIG. 6 , in the recirculation mode, the main bet flow path 112 communicates with the outside air flow path 111 by the recirculation damper 190 , and the bypass bet flow path 113 is connected to the bypass damper 180 . closed by The outside air intake port OA is closed by a damper.
