Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a ventilation unit,

The present invention relates to an integrated ventilating apparatus for cooling and heating, and more particularly, to a compact unit type in which all the components necessary for cooling and heating and ventilation are formed into one compact unit type, It is possible to perform the ventilation more efficiently by mixing the air and the outdoor air at different supply ratios, and to perform the cooling and heating while reducing the waste of electric power consumed in the indoor air cooling and heating, Air is supplied to the specific room, while the individual supply duct is installed to supply the air. In addition, a damper, which is a means for opening and closing the supply passage, is installed for each of the individual supply ducts. One-piece ventilation system combined with cooling and heating to reduce energy waste The.

An example of a ventilator according to the prior art is Korean Patent Laid-Open Publication No. 2000-51470 (entitled Ventilator for Combined Heat and Cooling).

As shown in FIG. 1, the prior art includes a hollow rectangular housing 1 in which components are installed in an internal space portion of a predetermined area; (2) having different air discharge and suction paths (22) (23) for mutual heat exchange between indoor and outdoor air; A plurality of vertical and horizontal partitions 3a and 3b for preventing mixing of indoor and outdoor air; (4a) and (4b) installed at the upper portion of the housing (1) with the vertical partition wall (3a) therebetween to forcibly suck indoor air, respectively; And an evaporator (5) (6) that secondarily cools and heats the outdoor air having undergone the primary heat exchange with the indoor air through the exhaust heat collector (2) to a temperature lower than or equal to a predetermined temperature.

However, the above-described conventional technique has the following problems.

First, an outdoor unit (not shown) for liquefying the high-temperature and high-pressure gas refrigerant introduced into the compressor (not shown) into a liquid refrigerant at room temperature and high pressure is installed outside the building separately from the prior art apparatus, Since they are interconnected through a pipe (not shown), there is a problem that installation and construction are cumbersome.

Secondly, in the conventional art constructed as described above, the turbid air on the indoor side is introduced through the 100% air inlet 12 and the fresh air on the outdoor side is introduced through the 100% air inlet 12, (2), so that it was not efficient in cooling and heating.

More specifically, assuming that the indoor air temperature at the time of cooling in summer is 25 ° C and the temperature at the outdoor side is 32 ° C, after these air passes through the exhaust heat collector 2, 28.5 캜.

The air having the temperature lowered to 28.5 deg. C is further cooled down to approximately 20 deg. C through the evaporator (5) until it is further heat-exchanged and then flows into the room again.

Therefore, in order to lower the temperature from 28.5 DEG C to 20 DEG C, there is a problem that the compressor is further driven and the electric power is wasted.

In addition, there has been a problem of inefficiency from the viewpoint of efficiency as the 100% fresh air from the outdoor side is sucked into the room again and the indoor air is 100% exhausted.

3, the heat exchanged air is discharged through the discharge port 11 into each room (not shown) of the room, although not shown in detail in the drawing, only a single discharge port 11 is formed, A single air supply duct (not shown) having a predetermined length is installed in the discharge port 11, and a branch duct (not shown) is installed in each room The discharge amount of the air discharged through the discharge port 11 can not be controlled at all.

For example, when a large amount of air is supplied only to a specific room, even if air supplied to other rooms is limited, since the air supply duct is formed as a single unit, There was a problem.

Fourthly, in the above-mentioned prior art, since the evaporator 5 is used to perform the cooling function and the separate heaters 6 and 7 are used to perform the heating function, the manufacturing costs There is a problem that the increase and the power for operating the heater are wasted.

The present invention has been conceived to solve the above-mentioned problems, and it is an object of the present invention to provide a refrigerator which can improve the convenience of installation and construction by constituting all the components necessary for cooling and heating and ventilation in one compact unit type, It is possible to perform the ventilation more efficiently by mixing the outdoor air with different supply ratios and to reduce the waste of electric power consumed in the cooling and heating of the room and to supply air individually to each room, And a damper as a means for opening and closing the supply passage is provided for each of the individual supply ducts to selectively supply air to only a specific room, while air is not supplied to the remaining unused rooms to reduce energy waste. An object of the present invention is to provide an integrated ventilation system for both cooling and heating.

The operation of the integrated ventilator for combined cooling and heating according to the present invention will be described as follows.

The function of the present invention is largely classified into three types of ventilation, cooling and heating.

First, the action of ventilation is explained as follows.

3, when the blowers B1 and B2 start to be driven, air and outdoor air are introduced through the indoor inlet 210 and the outdoor inlet 230, respectively, as shown in FIG. 2, The air begins to be inhaled forcibly.

Thereafter, the air is branched and introduced into the indoor side and outdoor side branch ducts 211 and 231 branched from the indoor side inlet 210 and the outdoor side inlet 230 respectively and then flows into the partition walls 140 and 141, S1 and S2 of the space S1, S2, S3, and S4 partitioned by the partition walls 142 and 143, respectively.

3, the indoor side and outdoor side air introduced into the upper left and right spatial parts S1 and S2 pass through different paths (path2) of the ventilation heat exchanger 130 Exchanged while crossing in a " X " shape, and then forcedly blown into the space portions 101 and 103 on both sides by the suction force of the blowers B1 and B2.

2 to 4, the air forcedly blown into the space portions 101 and 103 on both sides is discharged through the outdoor discharge port 240 and the indoor discharge port 250, respectively.

The air discharged through the indoor side discharge port 250 flows back into the room through a separate pipe or the like. The inflow air is heat-exchanged with the outdoor air, .

In other words, it is expected that the room will be ventilated when the window is opened for ventilation of the room.

In the present invention, the indoor side branch pipe 211 of the first and second fork 211a and 211b and the outdoor side branch duct 231 of the first and second fork 231a and 231b And a first adjusting means 400 including a control damper 410 which is rotatably installed in the passage to adjust the amount of air passing therethrough and a driving motor 420 which rotates the adjusting damper 410.

Accordingly, in the present invention, the rotation angle of the control damper 410 is changed so that the indoor side branch duct 211 and the first and second branches 231a, which are the first and second fork 211a and 211b, The indoor air and the outdoor air introduced through the indoor side and outdoor side inflow ports 210 and 230 can be supplied to the space portion S1 (S1) by changing the opening angle of the outdoor side branch pipe 231, ) S2 to be distributed at different ratios.

For example, the indoor air introduced through the indoor inlet 210 is branched into 7: 3 by the first and second branches 211a and 211b of the indoor branch pipe 211, The outdoor air introduced through the outdoor branching duct 230 is branched and divided into the first and second branches 231a and 231b of the outdoor side branch duct 231 so as to be 3: 7.

In this way, about 70% of the indoor air is introduced into the space S1 through the first fork 211a and the outdoor air is introduced by about 30% through the first fork 231a. Passing through path 2 of the ventilation heat exchanger 130 shown in Fig. 3)

30% of the room-side air flows into the space S2 through the second fork 211b and the outdoor air flows into the room S2 through the second fork 231b (refer to FIG. 3 Passes through path 1 of the ventilating heat exchanger 130)

The indoor and outdoor air supply structures of the present invention as described above are constructed such that 100% of indoor air and 100% of outdoor air are mixed and heat-exchanged, and then outdoor air is supplied to the indoor and indoor air is discharged to the outside The indoor air is not discharged to 100% and the outdoor air is not used as 100%, only a part of the air is mixed and heat-exchanged and then discharged into the room, and the remaining indoor / outdoor mixed air is discharged to the outside Because of the possibility of energy recycling and the waste of energy can be prevented.

In the present invention constructed as described above, air conditioning means capable of cooling during summer and heating in winter are provided.

The air conditioning means includes the space S1, S2, S3, and S4 partitioned by the partition walls 3, 3, 3, and 3 as shown in FIGS. 2, 3, The first and second heat exchangers 301 and 302 are disposed in the lower left and right spatial sections S3 and S4 respectively. The auxiliary housing 310 is fixed to the outer surface of the rectangular housing 100, And a four-way valve (350) installed in the auxiliary enclosure (310) for switching the flow of the refrigerant so that the room can be cooled and heated, The first and second heat exchangers 301 and 302, the compressor 340, and the four-way valve 350 are configured to perform a refrigerant cycle.

The second heat exchanger 302 is used as an evaporator during the summer season to cool and inspect the room air, and in winter, it is converted into a condenser to heat the room air.

The first heat exchanger 301 is opposite to the second heat exchanger 302, and is used as a condenser in the summer and as an evaporator in the winter.

And a first heat exchanger (301).

And a first heat exchanger (301).

Here, B1 and B2 shown in Figs. 5A and 5B are blowers.

The power consumption for driving the compressor 340 for compressing the refrigerant for indoor cooling and heating can be significantly reduced by the above-described air conditioning means and the aforementioned indoor-side / outdoor-side branching ducts 211 and 231.

Here are some possible reasons for this.

2 and 3, about 70% of indoor air of about 25 ° C flows into the space S1 through the first fork 211a and flows through the first fork 231a through the first fork 211a, (About 30%) of the outdoor side air flows through the path of the path 2 of the ventilation heat exchanger 130 shown in Fig. 3)

As described above, the temperature of the mixed air A after the indoor / outdoor air flows into the space S1 and is mixed is about 27.1 占 폚.

As shown in FIGS. 2 and 3, about 30% of indoor air of about 25.degree. C. flows into the space S2 through the second fork 211b and flows through the second fork 231b Deg.] (About 70%) flows through the path of the path 1 of the ventilation heat exchanger 130 shown in Fig. 3)

As described above, the temperature of the mixed air B after the indoor / outdoor air flows into the space S2 and mixed is about 29.9 ° C.

The mixed air A at about 27.1 ° C and the mixed air B at about 29.9 ° C are then exchanged with each other as they pass through different paths path 1 and path 2 of the ventilation heat exchanger 130.

The temperatures of the mixed air (A) and the heat exchanged air (B) are 25, 42 and 28.22 캜, respectively.

The heat exchanged mixed air (A) of about 25 ° C and about 42 ° C passes through a first heat exchanger (301) serving as an evaporator shown in FIG. 5a, The plurality of indoor side discharge ports 250 are finally discharged while flowing through the plurality of indoor discharge ports 250 to the room along a plurality of pipes (not shown).

On the other hand, the mixed air B at a temperature of about 28.22 ° C, which is heat-exchanged, passes through the second heat exchanger 302 serving as a condenser shown in FIG. 5A and the temperature is raised to pass through the outdoor side discharge port 240 ) And finally discharged.

Accordingly, in the present invention, since the temperature of the air passing through the heat exchanger serving as the evaporator can be reduced to about 5 ° C in order to lower the room temperature to about 20 ° C during the summer cooling, the driving time of the compressor is extended You do not have to give it .

As a result, the driving time of the compressor 340 is reduced to a minimum so that indoor cooling can be achieved more efficiently.

Since the driving time of the compressor 340 is shortened, power consumption can be reduced.

The description so far has described the case of indoor cooling in the summer.

Hereinafter, the case of indoor heating in winter will be described.

In the winter season, as shown in FIG. 2 and FIG. 3, about 70% of indoor air of about 23 ° C flows into the space S1 through the first fork 211a and the air flows through the first fork 231a, About 30% of outdoor air of about 12 DEG C flows (passing the path of path 2 of the ventilation heat exchanger 130 shown in Fig. 3)

As described above, the temperature of the mixed air A after the indoor / outdoor air flows into the space S1 and is mixed is about 12.5 ° C.

As shown in FIGS. 2 and 3, indoor air of about 23.degree. C. flows into the space S2 through the second fork 211b to about 30%, and flows through the second fork 231b, About 70% of outdoor air around 12 占 폚 flows (passing the path of path 1 of the ventilation heat exchanger 130 shown in Fig. 3)

As described above, the temperature of the mixed air B after the indoor / outdoor air flows into the space S2 and mixed is approximately -1.5 DEG C.

The mixture air A at about 12.5 ° C. and the mixed air B at about -1.5 ° C. are exchanged with each other while passing through different paths path 1 and path 2 of the ventilation heat exchanger 130.

The temperatures of the mixed air (A) and the heat exchanged air (B) are 4.1 ° C. and 6.9 ° C., respectively.

The heat exchanged mixed air (A) of about 4.1 캜 passes through the first heat exchanger (301) serving as an evaporator shown in Fig. 5 (b) The plurality of indoor side discharge ports 250 are finally discharged while flowing through the plurality of indoor discharge ports 250 to the room along a plurality of pipes (not shown).

On the other hand, the mixed air (B) at a temperature of about 6.9 캜, which is heat exchanged, passes through the second heat exchanger (302) serving as a condenser shown in FIG. 5B and the temperature is increased to pass through the outdoor side discharge port ) And finally discharged.

Accordingly, in the present invention, since the temperature of the air passing through the heat exchanger serving as an evaporator can be lowered to only about a predetermined value or less in order to raise the room temperature to about 23 ° C during the winter season, the driving time of the compressor is extended You do not have to give it.

As a result, the driving time of the compressor 340 is reduced to a minimum so that indoor cooling can be achieved more efficiently.

Since the driving time of the compressor 340 is shortened, power consumption can be reduced.

On the other hand, in the present invention, a plurality of indoor-side discharge ports 250 are provided, each of which can supply air individually in accordance with the number of rooms in a room, , A control damper (510) provided to be rotatable in the passage of each of the indoor side discharge ports (250) and adjusting the amount of air passing therethrough, and a drive motor (520) for individually rotating the control damper (510) The air is selectively supplied only to a specific room, while air is not supplied to the remaining unused room, thereby reducing energy waste.

As described above, according to the present invention, all the components necessary for cooling and heating and ventilation are constituted by one compact unit type, so that the convenience of installation and construction can be improved, and the supply of indoor air and outdoor air The mixing ratio is different from each other so that the mixing can be performed more efficiently and the waste of electric power consumed during the cooling and heating of the room can be reduced and the individual supply pipe is installed so that air is individually supplied to each room, A damper serving as a means for opening and closing a supply passage is provided for each of the individual supply pipes to selectively supply air only to a specific room, while air is not supplied to the remaining unused rooms, thereby reducing energy waste.
