Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a multifunctional air conditioning and ventilation system for ventilation and heat exchange between indoor air and outdoor air.

Conventional technology Conventionally, this type of multi-functional air conditioning ventilation system exchanges heat between supply and exhaust, which is useful for heating and cooling, but in the middle of the season when heating and cooling are not performed, such as in spring and autumn, the heat exchange element is unnecessary. Simultaneous supply/exhaust and heat generation are not possible because of the resistance during intake/exhaust and the inability to effectively utilize the ventilation capacity of the blower, and the need to install a separate circulator to circulate indoor air when outdoor air is contaminated or during intermediate periods. An exchange circulation function was added.

Such examples are shown in FIGS. 7 to 9. In the figure, 5
o is a box-shaped main body, inside thereof is a blower 52 having blades 51a and 51b on the left and right sides, a heat exchange element 53, and openings 54, 55, 58, 57, 58 on the outside.
, 59, 60.61 are provided. 62 is a plate that opens and closes the openings 54 and 59, respectively; 63 is an opening/closing plate that opens and closes the openings 66 and 61 and the openings 67 and 60 in combination.

In FIG. 8, the air conditioning ventilation device e4 is installed on a wall surface 65, and the openings 64 and 69 are closed by a plate 62 in order to perform heat exchange circulation. Also, the opening/closing plate 63 shown in FIG. 9 is moved so as to open the opening 56 and the opening 61. As a result, indoor air enters the main body 64 through the opening 66 in FIG. 8 and returns to the room through the opening 55 through the blades 51a of the blower 62, which flow from the lower left to the upper right in the drawing of the heat exchange element 530 in FIG. Similarly, outdoor air enters the main body 64 through the opening 61 shown in FIG. 8 and enters the heat exchange element 63 shown in FIG.
The air flows from the lower right to the upper left in the drawing and returns to the outdoors from the opening 5th by the blades 51b of the blower 52. At this time, the heat exchange element 63
The indoor and outdoor temperature and humidity are exchanged. Next, in order to perform simultaneous suction and exhaust heat exchange, the opening/closing plate 63 shown in FIG. 9 is moved to form openings 57 and SO. At this time, the plate 62 is in a closed state like the heat exchange circuit. As a result, indoor air enters the main body 64 through the opening 57 in FIG.
The air flows from the bottom right to the top left of the heat exchange element 63 in the figure, and is exhausted to the outside from the opening bottom 58 by the blades 61b of the blower 52. Similarly, outdoor air is supplied to the main body 6 from the opening 60 in FIG.
4, air flows from the bottom left to the top right of the heat exchange element 63 in FIG. 7 and is supplied into the room from the opening 66 by the blade 51a of the blower 62. At this time, temperature and humidity are similarly exchanged between the indoor and outdoor airflows. Finally, in order to carry out normal ventilation with simultaneous suction and exhaustion, the openings 64 and 59 shown in FIG. 8 are opened by the plate 62. As a result, indoor air enters the main body 64 through the opening 64 and is exhausted outside through the opening 68 by the blade s1b of the blower 52 shown in FIG. 7 without passing through the heat exchange element 63. Similarly, outdoor air enters the main body 64 through the opening 59 and is supplied into the room through the opening 55 by the blades 51 & of the blower 52 shown in FIG. 7 without passing through the heat exchange element 53. At this time, the opening 57 and the opening 6
o, or either the opening 56 or the opening 61 is open. (For example, Japanese Unexamined Patent Publication No. 57-6247) Problems to be Solved by the Invention In such a conventional configuration, the opening/closing plate and the plate for switching between heat exchange circulation, simultaneous intake/exhaust heat exchange ventilation, and normal ventilation are independent. However, if the plate is erroneously opened during heat exchange circulation and simultaneous heat exchange, it may become impossible to perform heat exchange circulation and simultaneous intake and discharge.

In addition, during normal ventilation with simultaneous intake and exhaust, the opening/closing plate is in the heat exchange circulation or heat exchange position with simultaneous intake and exhaust, and air gets mixed in.

Particularly in the heat exchange circulation position, air mixing occurs and the effective ventilation rate decreases. In addition, there are eight openings, and airflow passes through different openings depending on the function, so if the main unit is installed in the ceiling, there are many ducts and it becomes complicated, and the installation location is limited to the wall surface. Ta.

The present invention is intended to solve these problems, and aims to eliminate malfunctions in function switching, eliminate air mixing during simultaneous suction and exhaust, and eliminate restrictions on installation locations such as in the ceiling.

Means for Solving the Problems In order to solve this problem, the present invention provides a main body having an exhaust air passage and an air supply air passage, and an inflow portion at the intersection of the exhaust air and air supply air passages. a counterflow type heat exchange element having one location and two discharge portions for each of its inflow portions; a damper capable of alternately shielding discharge portions located diagonally among the discharge portions; The components include a damper that allows communication between the exhaust and supply air ventilation path before entering the element and the ventilation path in which the blower is placed, a damper opening/closing connection plate that drives the two types of dampers, and a motor. be.

Function: With this configuration, two types of dampers are sequentially operated by the damper opening/closing connecting plate driven by the motor. By switching the damper installed at the discharge part of the heat exchange element, it is possible to select between heat exchange circulation and heat exchange ventilation, and the damper can also be used to switch the blower from the heat exchange ventilation position by moving the damper opening/closing connection plate. By opening the damper for connecting the arranged ventilation passages, ordinary simultaneous intake and exhaust ventilation can be performed.

EXAMPLE An example of the present invention will be described below with reference to FIGS. 1 to 6. FIG. 2 shows a counter-flow type heat exchange element 1, which has a partition plate 2 having heat conductivity, a wavy spacing plate 3 to maintain the distance, and a stopper 4 to prevent airflow leakage. It is multi-layered.

A flow diagram of the airflow is shown in Figure 3. - Air flow A (exhaust air) exits from the top of the figure to either the left or right side (A1 or 7 or A2) of the lower part of the inlet. Similarly, the secondary air flow B (air supply) enters from the bottom surface and exits from either the left or right side of the upper side (B1 or B2). Heat exchange takes place through partition plates, and high efficiency is achieved due to the countercurrent flow.

Figure 1 shows the configuration of the air conditioning ventilation system. A heat exchange element 1 is provided within the main body ε, and blowers 6 and 7 for blowing air current. Dan-18 and 9 for changing the discharge part to switch between heat exchange ventilation and heat exchange circulation, rails 1o and 11 on which they move, seals 12 to 17 to prevent airflow from mixing, and normal simultaneous supply and exhaust. The dampers 18 and 19 for ventilation and the shaft 38.39 protruding from the p-bar 8.9 are inserted into the groove 40.41 of the damper opening/closing connection plate 2o in FIG. 4, and the shaft protruding from the damper 18.19. 42 and 43 are configured to touch the recesses 44 and 45 of the damper opening/closing connection plate 20,
The dampers 8, 9 and 18, 19 are switched by the motor 21.

Figure 1 shows the configuration during heat exchange circulation. When the dampers 8 and 9 drive the motor 21 so that the damper opening/closing connection plate 20 moves to the position C in FIG. 4, the airflow flowing inside the heat exchange element 1 changes from A to A in FIG.

B will now flow to B1. Therefore, indoor air 22'a
F) enters from the suction port at the upper left in the figure, passes through the heat exchange element 1, and is discharged into the room by the blower 7. Also, the outdoor air 23a
The air enters from the suction port at the lower right in the figure, passes through the heat exchange element 1, and is discharged to the outside from the blower 6. This allows indoor air to be circulated while simultaneously exchanging heat with outdoor air without mixing.

Figure 6 shows the configuration during heat exchange ventilation. When the motor 21 is driven so that the damper opening/closing connection plate 20 is at the position D in FIG. 4, the airflow flowing through the heat exchange element 1 changes from A to A2 in FIG. B flows to B2. Therefore, the indoor air 22b passes through the heat exchange element 1 that enters through the suction port on the upper left in the figure, is discharged from the discharge part (lower left in the figure) opposite to that during heat exchange circulation, and is exhausted outside the room by the blower 6. be done. Similarly, the outdoor air 23b enters the heat exchange element 1 through the suction port at the lower right in the figure.
Air is supplied into the room through the blower 7.

Figure 6 shows the configuration for normal ventilation with simultaneous suction and exhaustion. The motor 21 is driven so that the damper opening/closing connection plate 2o is at the position E in FIG.
Only 9 is activated. This is damper 1
This is to prevent exhaust air and supply air from being mixed even if the seals 8 and 19 are not perfect and a portion of the airflow flows into the heat exchange element 1. In addition, the damper 18 is used for switching from normal ventilation with simultaneous supply and exhaust to heat exchange ventilation or heat exchange circulation.
and springs 24 and 2 for returning 19 to their normal positions.
By opening the damper 18, which is attached at 5, until the seal 2eK3 is exposed, an opening 28 communicating with the passage 27 in which the blower 6 is arranged is opened, and the indoor air 22c is exhausted outside without passing through the heat exchange element 1. . Similarly, the damper 19 opened to the seal 29 opens an opening 31 communicating the passage 3° in which the blower 7 is disposed, and the outdoor air 23c is supplied into the room without passing through the heat exchange element 1.

As described above, according to this embodiment, heat exchange circulation and heat exchange ventilation can be performed by switching the two discharge ports of the counterflow type heat exchange element with a damper, and furthermore, the ventilation passages for exhaust and supply air can be performed. By opening the damper and the blower to allow ventilation, normal ventilation for intake and exhaust can be performed at the same time. This damper operation is driven by a single damper opening/closing connecting plate and a motor, which has a simple structure, eliminates malfunctions in function switching, eliminates airflow leaks, and creates an energy-saving and comfortable indoor atmosphere.

In the embodiment, an intermediate duct type was used, but the suction and discharge parts on the indoor side may be replaced with a decorative board, and the system may be changed to a wall-mounted type. Further, the heat exchange element may be of a sensible heat exchange type having only heat conductivity, or of a total heat exchange type capable of exchanging humidity as well.

Effects of the Invention As described above, the present invention includes a counterflow type heat exchange element having two discharge sections, a damper that can switch between the discharge sections, and a connecting plate for the exhaust and supply air passages. Driven by a motor, heat exchange circulation, heat exchange ventilation, and normal ventilation with simultaneous supply and exhaust are easily performed, there is no malfunction of function switching, there is no leakage of airflow, and there are indoor and outdoor suction and discharge ports. Since there are only four locations, there are no restrictions on where it can be used, such as intermediate ducts or wall hangings, and it has the effect of saving energy (creating a comfortable indoor atmosphere).
