The present invention relates to a ventilation recovery rate adjustable waste heat recovery combined air-conditioning and air conditioner, and to an efficient utilization of the installation space and to improve the control structure of the ventilation air amount.

Conventional ventilation recovery rate regulating waste heat recovery and air-conditioning air conditioner improves the efficiency of condenser or evaporator by utilizing heat pump air-conditioning as well as waste heat from the air exhausted from the inside of the room. By exchanging ventilate is to act.

This prior art is well represented in the "ventilation rate controlled waste heat recovery combined heating and cooling air conditioner" of the Republic of Korea Patent No. 354132 shown in Figures 1 to 3.

The technology shown in the Republic of Korea Patent No. 354 132 is generally in one case without separating the indoor unit (evaporator in cooling mode, condenser in heating mode) and outdoor unit (condenser in cooling mode, evaporator in heating mode). It has a built-in damper system that can properly mix outdoor air and indoor air.

Referring to Figures 1 to 3 in more detail the configuration of the prior art, the first heat exchange chamber 20 is provided with a first exchanger in a single case (1), the second heat exchange chamber (2) 30 is integrally formed, and a predetermined space portion is formed between the first heat exchange chamber 20 and the second heat exchange chamber 30, and the partition wall 40 divides the space into two portions in the center of the space portion, and the partition wall Based on (40), one side space includes an indoor side air suction chamber 50 and the other side includes an outdoor side suction air chamber 60, and dampers formed on both side surfaces of the indoor and outdoor side air chambers 50 and 60. And (52,53,62,63).

The first heat exchange chamber (20) has an indoor outlet (21), an air supply blower (22), a first heat exchanger (23), an evaporator drain plate (24), an expansion valve (25), and an air cleaning system. The filter 26 etc. are provided.

The second heat exchange chamber 30 is provided with an outdoor side discharge port 31, an exhaust blower 32, a second heat exchanger 33 serving as a condenser, a condenser drain plate 34, an expansion valve 35, and the like. .

The indoor air intake chamber 50 has an indoor air inlet 51 to which a single duct 70 extending from the inside of the building is connected, and the air introduced from the inside of the room comprises a first heat exchange chamber 20 and a second heat exchange chamber. The first damper 52, the second damper 53, and the like, which are arranged to flow in a predetermined ratio, are provided at 30.

The outdoor side air intake chamber 60 is divided into a predetermined ratio by dividing the outdoor side air inlet 61 and the outdoor side air into the first heat exchange chamber 20 and the second heat exchange chamber 30. The third damper 62, the fourth damper 63, the compressor 64, and the like, which are adjusted to flow in the air, are installed.

The controller 66 determines whether the controller 66 is air-conditioned according to a signal detected by a temperature-humidity detection unit (not shown) in the case 1 to control the opening of the four-return valve 65 and the dampers.

Figure 2 is a diagram illustrating the operation in the cooling mode of the conventional air-conditioning combined heat recovery and cooling air-conditioning air conditioner, it is assumed that the amount of 30% when replacing the ambient air when circulating the indoor air.

In this case, the opening degree of the second damper 53 and the third damper 62 is set to about 70%, and the opening degree of the first damper 52 and the fourth damper 63 is set to 30%.

After the indoor and outdoor air enters the air inflow passage 600, 30% of the hot outdoor air for ventilation through the second damper 53 and 70% of the cold outdoor air through the fourth damper 63 is exchanged for the first heat exchange. After being introduced into the chamber 20 and mixed in the air mixing space 610, the heat exchanged and cooled while passing through the evaporator 23 is supplied to the room through the indoor air outlet 21.

In addition, after the 30% of cold indoor air and the 70% of hot outdoor air enter the second heat exchange chamber 30 through the first damper 52 and the third damper 62, the condenser 33 is mixed. After absorbing the condensation heat while passing through, it is discharged to the outside through the outdoor air discharge port (31).

In the heating mode shown in FIG. 3, the flow of air is the same as that of the cooling mode, and the refrigerant flow is switched to the four reverse valves 65 to convert the evaporator 23 into a condenser and the condenser 33 into an evaporator. Heating is done.

The prior art as described above has the advantage that can improve the efficiency of the condenser and the evaporator, and can also be ventilated at the same time heating and cooling, there are the following problems.

First of all, since the air conditioner of this field consists of the indoor unit and the outdoor unit as an integrated unit, there is a problem in that a large installation space is secured by increasing the volume of the device.

In particular, the conventional air conditioner, the main components constituting the device is installed in a row in a long direction in the horizontal direction, in this case, the design of the device is easy, but there is a problem that the shape of the installation space should be secured in a rectangular shape accordingly. That is, depending on the building, there may be a place where there is not enough space in the longitudinal direction or an obstacle such as a building pillar. In this case, since a long rectangular installation area cannot be secured, it is impossible to install an integrated air conditioner as in the conventional art. It becomes

In addition, the air-conditioning and air conditioner of the prior art as described above is controlled by the angle of the damper blades to control and close the amount of indoor air and outdoor air, the wind direction or air volume is controlled.

However, if the air flow is controlled only by the opening of the damper, it is not easy to uniformly form the air mixing ratio of the outdoor inlet air circulated from the outside for circulation and the indoor inlet air circulating.

That is, a malfunction occurs frequently when the opening amount of the damper is controlled by the controller. Accordingly, the conventional apparatus does not properly form a uniform air mixing ratio, and a problem of lowering the efficiency of the air conditioner occurs.

Also, as shown in (B) and (C) shown in FIG. 9, when the air flow is only controlled by the damper vane, the blade angle of the damper is always inclined by a certain amount of ventilation, except when no ventilation is performed at all. In this case, the passing air hits the vane of the damper to generate noise and vibration, and the repeated operation of the damper opening adjuster also causes frequent failure of the device and shortening of the machine life.

 The present invention has been proposed to solve the problems of the prior art, by reducing the area and space occupied by the apparatus by forming a blower portion of the components of the air conditioner arranged in a rectangular shape in a double layer, it was a conventional idle space It is an object to make efficient use of the upper space of the apparatus.

In addition, the present invention is modified to install the structure of the bulkhead when operating at the basic ventilation rate of the environment used to make the wings of the damper in the fully open state, the amount of air introduced and mixed in the indoor and outdoor to be made at the damper area ratio without adjusting the damper As a result, the noise and vibration caused by the air passing through the damper are minimized.

According to the present invention, an air conditioner case is formed in a double layer, and a blower part is disposed on an upper layer of a heat exchanger to separately configure a blower chamber, and a blower inlet passage 400 in which air passing through the heat exchanger is guided to an upper blower chamber in a heat exchange chamber is provided. The main feature is the configuration in which the structure is formed.

The overall configuration of the present invention is as follows.

A first heat exchange chamber provided with a first heat exchanger as a space in which air flow is discharged into one case, a second heat exchange chamber provided with a second heat exchanger as a space in which air flow is discharged to the outside, and the first heat exchange chamber and a first heat exchange chamber An air inflow passage 600 consisting of a predetermined space is formed between the two heat exchange chambers, and the air inflow passage 600 includes an indoor inflow air and an outdoor inflow air for the first heat exchange chamber 20 and the second heat exchange chamber 30. The partition wall is divided into a predetermined ratio so that the amount of water flowing into the chamber, and the indoor air suction chamber on one side, and the outdoor air suction chamber on the other side, and the indoor and outdoor air suction chamber And a damper for controlling the flow rate of air at a position at which air is discharged and introduced into the first heat exchange chamber and the second heat exchange chamber.

The present invention featuring such a configuration will be described in detail with reference to the embodiments illustrated in FIGS. 4 to 9 as follows.

Figure 4 is a partial cutaway perspective view of an embodiment of a multi-layer ventilation recovery rate adjustable waste heat recovery combined air conditioning air conditioner according to the present invention, Figure 5 is a schematic diagram for explaining the operation of the cooling mode of the embodiment, Figure 6 is a heating mode of the embodiment Figure 7 is a schematic diagram for explaining the operation of, Figure 7 is a block diagram of the forced water sprinkling means configured by the present invention, Figure 8 is a block diagram of a refrigerant flow type heat pump to which the present invention is applied.

As shown in FIG. 4, the present invention is formed on the first heat exchange chamber 20 and the first heat exchange chamber in which the first heat exchanger 23 is installed in the case 1, and the air supply blower 22 is placed therein. The second blower chamber 300 formed above the second heat exchange chamber 30 and the second heat exchange chamber in which the first blower chamber 200 and the second heat exchanger 33 are installed, and in which the exhaust blower 32 is placed, is disposed. Has the basic configuration of

The first air blowing chamber 200 and the second air blowing chamber 300 have air inflow paths opened by the first heat exchange chamber 20, the second heat exchange chamber 30, and the air blowing chamber inlet passage 400, respectively. .

The ventilation chamber inflow passage 400 is formed by opening the upper and lower boundary surfaces of one end of the case, that is, the ends of the upper blower chamber and the lower heat exchange chamber. When the open portion is opened to the damper beyond the heat exchanger, air without heat exchange may be introduced, so the limit of the open portion should be limited at the rear end of the heat exchanger.

With this structure, the heat exchange chamber at the bottom of the case needs only to form an air flow in the rear portion of the heat exchanger to the upper blower chamber, thereby significantly reducing the installation area compared to the case where the conventional blower is installed at the rear of the heat exchanger. .

In addition, the inner side air suction chamber 50 and the outdoor side air suction chamber 60 are formed in the center of the case 1, and the suction chambers are installed between the air blowing chambers above the case 1.

The lower portion of the suction chambers are formed with a constant space portion, which is an air inflow passage 600 through which air is distributed to the first heat exchange chamber 20 and the second heat exchange chamber 30 formed at both sides thereof.

First to fourth dampers 52, 53, 62, and 63 are installed between the air inflow passage 600, the first heat exchange chamber 20, and the second heat exchange chamber 30 to control the amount of air flowing therethrough.

In addition, the air inflow passage 600 is divided into a partition wall 40 is installed obliquely inclined so that the air introduced from the indoor and the air introduced from the outside is not mixed with each other, in the present invention, the slope of the partition wall 40 is the first to the first Four dampers (52, 53, 62, 63) to determine the size of the element.

In the embodiment shown in Figure 4 of the present invention, the area ratio occupied by the damper installed toward the first heat exchange chamber 20 is the second damper 53 and the outdoor air inflowing the indoor air by the partition wall 40 is installed obliquely. In the ratio of 7: 3 to the fourth damper 63 into which the gas is introduced, and the second heat exchange chamber 30 has the first damper 52 into which the indoor air flows and the third damper 62 into which the outdoor air flows. It shows the state configured by dividing by 3: 7 ratio.

This ratio is not necessarily fixed and may be designed at an appropriate ratio depending on the use environment of the device.

That is, in general, in an environment where the ventilation rate of an air conditioner such as a restaurant or a theater is to be increased, an area ratio of the second damper 53 into which indoor circulation air is introduced and the fourth damper 63 into which outdoor air is introduced is 7: 3, It can be adjusted to about 6: 4, the partition wall 40 is inclined to the air inlet passage 600 in accordance with this area ratio to form a difference in the divided area.

In addition, since the ventilation rate of the air conditioner does not have to be high in an environment with low air pollution such as a general office or a museum, the ratio may be about 8: 2 or 9: 1. By adjusting, the area ratio of the damper can be divided.

As described above, in designing the air conditioner, the area ratio of the damper according to the mixing ratio of cold air and hot air is determined, and the installation inclination of the partition 40 is determined so as to divide the space according to this area ratio.

The reason for configuring the case 1 by dividing the area ratio of the damper from the time of designing the air conditioner in consideration of the ventilation rate according to the use environment of the air conditioner as described above is that, in most cases, the ventilation rate set once during operation of the air conditioner Because rarely change the. For example, multi-use facilities such as theaters and offices almost always accept a certain number of people, so it is not necessary to change the initial ventilation rate frequently.

Thus, when the damper separated by the partition 40 is operated at the initial ventilation rate, the damper blades are always kept fully open, and thus the damper blades and passages as shown in FIG. Since the air flow is parallel, the damper wing and the passing air collide, minimizing the noise and vibration.

  Of course, when it is necessary to ventilate at a rate other than the initial set ventilation rate, the ventilation amount is controlled by adjusting the opening degree of the first to fourth dampers 52, 53, 62, and 63.

The dual-layer ventilation recovery rate adjustable waste heat recovery combined air-conditioning air conditioner having the above configuration will be described below by dividing the principle of operation into a cooling mode and a heating mode based on the flow of air.

Figure 5 shows the cooling mode of the multi-layer ventilation recovery rate adjustable waste heat recovery combined air-conditioning air conditioner according to the present invention.

The dotted line indicates the refrigerant pipe, the arrow indicates the refrigerant flow, the thick and thin arrow indicates the air flow route, and the black line is the flow route of the outside air introduced into the outdoor side. The flow route of air. However, although the indoor and outdoor side air is separated and flown in the drawing, in practice, most of the space between the heat exchanger and the damper is mixed and mixed air.

The air discharged from the room is supplied to the indoor air suction chamber 50 through the duct 70 and the indoor air suction port 51, and the indoor air discharged is discharged from the first heat exchange chamber 20 and the second heat exchange chamber ( The air blower 22 and the air blower 32 installed in each of the air blowers 32 are respectively driven through the first damper 52 and the second damper 53 to flow along the respective air flow routes, and the air supplied from the outside It is supplied to the outdoor side air suction chamber 60 and flows along each air flow route through the third damper 62 and the fourth damper 63.

The indoor and outdoor air passing through the second damper 53 and the fourth damper 63 is mixed, filtered through the filter 26, and passed through the first heat exchanger 23 acting as an evaporator. Heat exchanged and cooled, the cooling air flows into the room through the indoor air discharge port 21, and continues in a cycle flowing through the duct 70 and the indoor air inlet 51 to the first heat exchanger 23. It will cool the room while cycling.

In addition, a large amount of condensate is generated in the first heat exchanger 23 and is collected in the evaporator drain plate 24. When a constant water level is ensured in the evaporator drain plate 24, the condensate pump 71 drains the evaporator. The cooling water of the plate 24 is supplied along the condensed water supply pipe 73 and sprayed toward the second heat exchanger 33 serving as a condenser in each injection hole of the cooling water sprayer 72, Improve the efficiency.

After the air passing through the first damper 52 and the third damper 62 is mixed and absorbed the heat of condensation of the refrigerant while passing through the second heat exchanger 33, the outside is discharged through the outdoor discharge port 31. To be discharged.

In the cooling mode described above, as illustrated in FIG. 5, the size of the damper is configured such that the ratio of the second damper 53 and the fourth damper 63 is 7: 3 according to the design structure of the partition wall 40. Therefore, 70% of cold indoor air flowing into the second damper 53 and 30% of hot air flowing into the fourth damper 63 are removed while passing through the evaporator 23, and the cooling air is indoors. It is supplied to the room through the side discharge port 21.

In addition, the ratio of the size of the first damper 52 and the third damper 62 is also 3: 7 according to the design structure of the partition wall 40 so that the first damper 52 is removed from the indoor air suction chamber 50. 30% of cold indoor air and 70% of hot outside air introduced through the third damper 62 are mixed in the indoor air intake chamber 60, and the predetermined temperature is lowered. The efficiency of the second heat exchanger 33 is improved by removing heat from the second heat exchanger 33 by passing through the second heat exchanger 33.

  Figure 6 shows the heating mode of the air-conditioning air conditioning combined with the recovery rate of ventilation recovery waste heat recovery according to the present invention, the flow of the refrigerant is reversed to the cooling mode.

That is, in the heating mode, the second heat exchanger 33 serving as the condenser in the cooling mode changes to the evaporator, and the first heat exchanger 23 serving as the evaporator changes to the condenser. However, the airflow route of the thick and thin arrows does not change.

In the heating mode, the cooling air, which is discharged from the room and supplied to the indoor air suction chamber 50 through the duct 70 and the indoor air suction port 51, is connected to the first damper 52 and the second damper 53. It flows along each air flow route, and hot air supplied from the outside to the outdoor air intake chamber 60 through the outdoor air intake port 61 passes through the third damper 62 and the fourth damper 63. It then flows along each airflow route.

  The indoor and outdoor air passing through the second damper 53 and the fourth damper 63 is mixed with cold and hot air at a ratio of 7: 3 by the design structure of the partition 40 and the size of the damper. The heat exchanger is heated while passing through the condenser 23, and the hot air flows into the room through the indoor air outlet 21, and the air heated in the room is again the duct 70 and the indoor air inlet 51. Through repeated cycles flowing back to the condenser 23 is heated.

In addition, according to the design structure of the partition 40, the size ratio of the first damper 52 and the third damper 62 is also 3: 7, so that the indoor side air suction chamber 50 passes through the first damper 52. The predetermined temperature is increased by mixing 30% of the hot indoor air discharged and 70% of the cold external air discharged through the third damper 62 in the outdoor side air suction chamber 60, and the mixed air is evaporator ( The evaporation efficiency is improved by absorbing heat from the evaporator 33 through the 33 and is discharged to the outside through the outdoor side discharge port 31.

The present invention not only greatly reduces the area occupied by the apparatus by arranging a blower, which is one of the constituent elements occupying the largest area, by forming the casing of the air conditioner in a double layer as the upper part of the heat exchanger. The effect of making the upper space of the device effective was obtained. Therefore, there is an advantage that can be easily installed in the field where the long installation area of the rectangular like a conventional air conditioner is not secured.

In addition, the present invention has the structure that the ventilation rate of the circulating air is initially set according to the use environment of the device itself, there is an advantage that can secure the necessary ventilation rate without the damper adjustment.

That is, since the present invention is initially set to the most commonly used ventilation rate, in this state, the blades of the damper are completely opened to maintain parallel to the air flow, thereby minimizing noise and vibration caused by the air passing through the damper.

In addition, if necessary, it is possible to set the required ventilation rate by adjusting the blade angle of the damper, which has the advantage that other ventilation rate variable functions are still maintained.
