The ventilator is operated by discharging the contaminated indoor air to the outside by using a blower, introducing outdoor air into the room, or filtering and recirculating the indoor air. Since the ventilation device is intended to maintain indoor air cleanness by exchanging or circulating indoor and outdoor air without changing the room temperature as much as possible, the rate of air exchange or the amount of air exchange per unit time does not significantly change the room temperature. It should be limited to the extent that it does not.

In particular, in winter when indoor heating is performed, the request for such a function is further increased. However, such a ventilation device has a limit in maintaining the indoor temperature due to structural and functional limitations.

Hereinafter, with reference to the accompanying drawings will be described in detail a heating ventilator having a leakage function using a binary cycle heat pump of the present invention.

3 is a view showing the configuration of a heating ventilator having a leakage function using a binary cycle heat pump according to the basic concept of the present invention.

Leakage refers to the discharge or consumption of some air volume by mixing, not completely independent circulation of the outside and the inside of the ventilator to the outdoor side or the outside side. In the concept of the present invention, the flow path between the outside and the inside of the ventilator is Presents configurations where discharge is performed after some or all of its inflow is mixed, rather than directly from the indoor and / or outdoor side to the outdoor and / or indoor side, and the amount of air mixed In addition to the concept that can be adjusted, the concept of leakage described above is a mixture of indoor air and outdoor air is partially mutually discharged to the other side, as well as a state in which mixing is not made when the mixing amount is controlled It should be noted that it can be understood as included.

The heating ventilator having a leakage function using the binary cycle heat pump of the present invention is basically a heat exchanger (10) and a heat exchanger (10) which are disposed on a path for inhaling the outside air and the inside air and discharge it to the indoor side, and heat-exchange A first cycle 100 in which a flow path, which is a predetermined pipe communicating with 10 and flowing with the refrigerant, is formed, and a second cycle 200 for heat transfer through the heat exchange unit 20 to the first cycle 100; And an outside air heat exchanger 30 constituting a part of the flow path of the second cycle 200 and disposed on a path for inhaling the inside and outside air and discharging it to the outdoor side, wherein the inside and outside air are primarily mixed. Flows into space.

Each of the first cycle 100 and the second cycle 200 is a cycle in which refrigerant flows independently, and as described later, a heat exchange part exchanges heat from outside air absorbed by the second cycle 200 during a heating operation of the ventilator. As a two-stage cycle to transfer to the first cycle 100 through the 20, and to transfer the heat of the refrigerant heated in the first cycle 100 to the bet introduced into the room through the internal air heat exchanger (10) It is composed.

Therefore, there is an advantage that the heating efficiency is further improved even when the outside temperature is low, unlike the case of a single cycle of the prior art. In particular, in the ventilation apparatus, it should be noted that a conventional heat pump is composed of one heat pump, and the problem of rapidly decreasing heating efficiency according to the circulation of air and the surrounding environment of the heat exchanger can be solved.

Here, the first cycle 100 and the second cycle 200 is a modular system in which independent flows are formed, respectively, the refrigerant circulating in the first cycle 100 is the first refrigerant, the second cycle 200 The refrigerant circulating is defined as the second refrigerant to be used. The refrigerant circulating in the first cycle 100 and the second cycle 200 may perform a cycle in which a predetermined flow occurs while the phase changes while compressing, expanding, and exchanging heat while moving along a predetermined flow path to function as a heat pump. do.

In the concept of the present invention, the first cycle 100 functions as a direct heating, and the second cycle 200 performs a function of heat transfer thereto. Here, when the heating is performed, the external air heat exchanger ( Absorbs and heats the heat of 30 and transfers it to the first cycle 100 through the heat exchange unit 20. The refrigerant heated by the heat transfer in the first cycle 100 receives the heat-resistant heat exchanger 10. A cycle of finally transferring heat to the outside air sucked into each other is achieved.

That is, in the basic concept of the present invention, the dual cycles of the first cycle 100 and the second cycle 200 operate independently and provide a system in which the heating efficiency is maximized in a simple manner.

In more detail, the configuration of the first cycle 100, the first compressor 110 for compressing the first refrigerant, the outlet of the first compressor 110 and the first communication with the heat exchanger (10) The expansion valve 121, and the internal air heat exchanger 10 which is connected to one side of the outlet of the first expansion valve 121.

Here each heat exchanger or heat exchanger (10, 20, 30) has a function of heat transfer between different systems, each having an independent pipe that can be communicated independently. The heat exchanger 20 is preferably a plate type heat exchanger (plate type heat exchanger) in consideration of the efficiency of heat transfer between the refrigerant is not necessarily limited thereto. In addition, the heat exchanger (10, 30) is to perform a function as a condenser or evaporator, respectively, as will be described later bar heat exchanger of various types, such as a dry evaporator, a full evaporator, a half full liquid evaporator, a forced liquid circulation evaporator, etc. It should be noted that the meaning is not limited to the type of description of the present invention.

In the first cycle 100, the refrigerant is circulated to directly heat the indoor air. When the first compressor 110 is operated, the compressed first refrigerant passes through a flow path communicating with the internal air heat exchanger 10. Inflow and outflow, where heat is released to the liquid of low pressure and high pressure while heating the bet circulating the room. At this time, the heat-resistant heat exchanger 10 during heating is operated as a condenser of the refrigerant.

The first refrigerant flowing through the internal air heat exchanger 10 flows into the liquid at low temperature and low pressure through the first expansion valve 121 and flows in and out of one side of the heat exchanger 20 to absorb heat and thereby absorb the first compressor 110. Is entered again. Here, the heat exchanger 20 is operated as an evaporator.

The second cycle 200 may include a second compressor 210, a heat exchanger 20 connected to an output side of the second compressor 210, and performing heat exchange with the first cycle 100, and the heat exchanger. A second expansion valve 221 connected to the other side of the part 20 to expand the second refrigerant flowing in a low temperature state, and an outside air connected to the second expansion valve 221 to exchange heat between the outside air and the second refrigerant; It consists of a heat exchanger (30).

In the second cycle 200, the second refrigerant is circulated in order to heat the first refrigerant through the heat exchanger 20. When the second compressor 210 operates, the second refrigerant is compressed. The inflow and outflow to the other side through the flow path communicating with the heat exchanger 20, and discharges heat while heating the first refrigerant flowing to one side of the heat exchanger 20 flows into the liquid of low temperature and high pressure. At this time, the heat exchanger 20 during heating is operated as a condenser of the second cycle 200.

The second refrigerant flowing through the heat exchange part 20 flows into the liquid at low temperature and low pressure through the second expansion valve 221, flows into the outside air heat exchanger 30, absorbs heat, and returns to the second compressor 210. Is entered. In this case, since the second cycle 200 heats the second refrigerant through the heat of the outside air and transfers the heat to the first refrigerant through heat transfer between the refrigerants, heating efficiency is higher than that of the conventional single cycle heat pump. This can be maximized.

In addition, the first cycle and the second cycle further include the dry (120a, 220a) and the liquid level gauges (120b, 220b) on the path of the refrigerant flowing into the first expansion valve 121 and the second expansion valve 221, respectively. It can be provided.

Dry (120a, 220a), to prevent the remaining liquid refrigerant from the evaporator, it is possible to prevent damage to the refrigerant device by preventing the liquid refrigerant to flow into the compressor. In addition, the liquid level gauges 120b and 220b are devices for indicating the liquid level position of the refrigerant, and various liquid level position display methods such as gauge glass, float type, or constant pressure type may be selectively applied.

In addition, an oil separator 220e may be additionally disposed on the flow path of the second refrigerant from the second compressor 210 to the heat exchange unit 20. The oil separator 220e may be mounted on the compressor discharge pipe to discharge gas. By separating the oil component contained in the oil can be prevented from flowing into the heat exchange unit (20). The oil separator 220e may be applied to the first cycle, of course.

In addition, a liquid separator 220d may be further disposed on a path from the outdoor heat exchanger 30 to the second compressor 210, and the liquid separator 220d may be configured to provide a liquid refrigerant when the liquid is mixed in the intake gas. In this case, only the refrigerant in a vaporized state may be introduced into the compressor, and the liquid separator 220d may be similarly applied to the first cycle.

In addition, a receiver 220c may be further disposed on the flow path of the refrigerant from the heat exchanger 20 to the second expansion valve 221, and the receiver 220c may be a heat exchanger 20 that acts as a condenser. Temporarily stores the refrigerant liquid at a high temperature and high pressure.

Hereinafter, the first cycle 100 and the second cycle 200 will be described based on a flow path that is a pipe through which flow is circulated.

The first cycle 100 includes a first heating passage 161 communicating with the heat exchanger 10 from the output side of the first compressor 110 and the first expansion valve from the air exchanger 10. A second heating passage 162 communicating with one side of the heat exchange part 20 and 121 and a third heating passage communicating with an input side of the first compressor 110 from one side of the heat exchange part 20 ( 163).

In addition, the second cycle 200 may include the first heating passage 261 communicating with the other side of the heat exchange part 20 from the output side of the second compressor 210, and the second cycle 200 from the other side of the heat exchange part 20. A second heating passage 262 communicating with the expansion valve 221 and the outside air exchanger 30, and a third heating passage communicating with the input side of the second compressor 210 from the outside heat exchanger 30; It consists of 263.

Figure 4 is a view showing a process of operating the heating of the heating ventilator having a leakage function using a two-cycle heat pump of the present invention.

When the first cycle starts to operate, the first compressor 110 starts a compression operation, and the first refrigerant compressed by the first compressor 110 passes through the first heating passage 161 to the internal air heat exchanger 10. In and out of the furnace, heat is released to the bet circulating in the room.

The first refrigerant that has undergone heat exchange in the internal air heat exchanger (10) flows through the second heating passage (162) in a liquid state of low temperature and high pressure, is input to the first expansion valve (121), and changes to a liquid state of low temperature and low pressure. The unit 20 receives heat from the second refrigerant of the second cycle 200 and enters the first compressor 110 again through the third heating passage 163 in a high temperature low pressure state. In the process, the heat exchanger 20 may function as an evaporator of the first refrigerant.

Meanwhile, in the second cycle 200, the operation of the second compressor 210 is started. The operation of the second compressor 210 may be performed simultaneously with the first compressor 110 or may be performed at a time interval to be.

Here, when the initial operation is started, the operation may be performed in such a manner that the temperature of the first refrigerant is first raised and the temperature of the second refrigerant is sequentially raised.

When the operation of the second compressor 210 starts, the predetermined solenoid valve is opened to communicate with the flow path of the heating cycle, and the high temperature second refrigerant compressed by the second compressor 210 is the first heating path 261. The heat is supplied to the other side of the heat exchanger 20 along the first refrigerant flowing in one side.

The second refrigerant cooled by the heat exchange unit 20 flows through the second heating passage 262 and flows into the outside air heat exchanger 30 in a liquid state of low temperature and low pressure through the second expansion valve 221. The outside air heat exchanger (30) absorbs the heat of the outside air, changes to a gas of high temperature and low pressure, and is reduced back to the second compressor (210) via the third heating channel (263).

In the heating process as described above, the heating passage 40 passes through the process of transferring the temperature to the first cycle 100 by utilizing the temperature transmitted to the members disposed on the outdoor side by the second cycle 200 and increasing the temperature again. In the end, the heating temperature can be obtained more efficiently.

Since the first cycle 100 and the second cycle 200 for heating as described above have separate flow paths as separate heat pumps, and heat is transferred only through the heat exchange unit 20, heating efficiency is improved. This can be maximized.

On the other hand, in the case of the heating ventilation apparatus according to the concept of the present invention, by changing the positions of the internal air heat exchanger 10 and the outdoor air heat exchanger 30 to the indoor side, it is also possible to obtain the function of cooling.

In addition, in the present invention, the circulation path between the bet and the outside air is not formed in an independent flow path as will be described later. It can be discharged separately.

The amount of inside or outside air flowing in or out through the mixing space may be controlled through a predetermined mixing amount adjusting member, which will be described later.

According to the above concept, for example, in the initial stage of heating operation, when the outside temperature of the outside air heat exchanger 30 is extremely low and the operation of the second cycle 200 for warming is not smooth, the temperature is somewhat higher. By introducing more air into the mixing space of the room may have the advantage of further improving the performance of the heating acceleration.

In addition, according to the arrangement of the mixing control member can be made to completely block the inflow of outdoor air.

In the above, the case of heating has been described. In this case, when the necessity of cooling exists, there is a need to change the arrangement of the entire housing (1100 of FIG. 9) supporting the heat exchangers 10 and 30 and the pipes. In order to solve this problem, the concept of a ventilation device that can simultaneously perform the function of cooling and heating in the same arrangement by controlling the flow of the refrigerant is proposed.

5 is a view showing the arrangement of the heating ventilator having a leakage function using a binary cycle heat pump according to an additional concept of the present invention.

The flow path and operation of the heating cycle described above will be omitted. Here, in the additional concept of the present invention, there is a difference in which the heating mode of the first cycle is defined as the heating cycle and the heating mode of the second cycle is defined as the heating cycle.

In addition, the first cycle and the second cycle, respectively, the dry (120a, 220a) and the liquid level gauges (120b, 220b) on the path of the refrigerant flowing into the first expansion valve 121 and the second expansion valve 221, respectively. And a liquid separator on a path from the second compressor 210 to the heat exchange part 20 to the oil separator 220e and a path from the external heat exchanger 30 to the second compressor 210. 220d may be further disposed.

The operation of the heating cycle and the heating cycle described above is as described in the basic concept of the present invention, but as described below, the first cycle may have a cooling cycle and the second cycle may have an endothermic cycle. Note that this is defined and used.

Therefore, it will be described in more detail with respect to the operation of the cooling according to an additional concept of the present invention.

In this case, since the internal heat exchanger 10 should be operated as an evaporator, the internal heat exchanger 10 receives heat from the internal air discharged from the cooling cycle of the first cycle 100 and heats it to the endothermic cycle through the heat exchanger 20. Transfer and warm to discharge the heat from the outdoor heat exchanger (30).

That is, in the additional concept of the present invention, the dual cycles of the first cycle 100 and the second cycle 200 operate independently, and the heating and cooling cycles, the heating cycles, and the endothermic cycles are respectively provided. It is possible to provide a system that maximizes the efficiency of heating and cooling in a simple manner by switching.

Here, the cooling cycle of the first cycle 100 is to share the heating cycle and the internal air heat exchanger 10, the heat exchanger 20 and the first compressor 110, the cooling cycle is the first to compress the first refrigerant The compressor 110, the heat exchanger 20 communicating with the outlet of the first compressor 110 at the other side, the third expansion valve 122 communicating with one side of the heat exchanger 20, and the third It consists of an internal heat exchanger (10) connected to the outlet of the expansion valve (122) and the input side of the first compressor (110).

The can be made with three branch flow path 173 is the same as that of the basic concept.

As the first cycle 100 includes the flow path as described above, the first branch flow path 171 and the third heating flow path 163 join adjacent to the first compressor 110, and the second branch flow path 172 and the second heating passage 162 and adjacent to the heat exchange unit 20, and the third branch flow passage is adjacent to the first heating passage 161 and the heat-resistant heat exchanger (10).

At this confluence point, there is a possibility that the low temperature low pressure refrigerant and the high temperature high pressure refrigerant may be mixed in accordance with the selective operation of the heating mode or the cooling mode, and an additional counter flow prevention means (not shown) is disposed to remove the refrigerant. Can be.

In addition, a plurality of valves may be disposed on the flow path in order to control the flow of the heating cycle and the cooling cycle of the first cycle 100.

In addition, the heating cycle of the second cycle 200 is the first heating flow path 261 communicated with the other side of the heat exchange unit 20 from the output side of the second compressor 210, and the other side of the heat exchange unit 20 A second heating flow passage 262 communicating with the second expansion valve 221 and the outside air heat exchanger 30, and a second communication path communicating with the input side of the second compressor 210 from the outside air heat exchanger 30. It consists of three warm flow paths (263).

In addition, the endothermic cycle of the second cycle 200 is branched from a portion of the second heating passage 262 and the first endothermic to communicate the other side of the heat exchange unit 20 and the input side of the second compressor 210.

Counter flow prevention means may be arranged.

7 is a view illustrating a process in which heating of a heating ventilator having a leakage function using a two-cycle heat pump according to an additional concept of the present invention is operated.

When the heating cycle starts to operate, the first compressor 110 starts a compression operation, and the first refrigerant compressed by the first compressor 110 passes through the first heating passage 161 to the internal air heat exchanger 10. Inflow and outflow release heat to the bet circulating in the room.

The first refrigerant that has undergone heat exchange in the internal air heat exchanger (10) flows through the second heating passage (162) in a liquid state of low temperature and high pressure, is input to the first expansion valve (121), and changes to a liquid state of low temperature and low pressure. The unit 20 receives heat from the second refrigerant of the second cycle 200 and enters the first compressor 110 again through the third heating passage 163 in a high temperature low pressure state. In the process, the heat exchanger 20 functions as an evaporator of the first refrigerant.

Meanwhile, in the heating cycle of the second cycle 200, the operation of the second compressor 210 is started, and the operation of the second compressor 210 may be simultaneously performed with the first compressor 110 or at a time interval. Of course.

Here, when the initial operation is started, the operation may be performed in such a manner that the temperature of the first refrigerant is first raised and the temperature of the second refrigerant is sequentially raised.

When the operation of the second compressor 210 starts, the predetermined solenoid valve is opened to communicate with the flow path of the heating cycle, and the high temperature second refrigerant compressed by the second compressor 210 is the first heating path 261. The heat is supplied to the other side of the heat exchanger 20 along the first refrigerant flowing in one side.

The second refrigerant cooled by the heat exchange unit 20 flows through the second heating passage 262 and flows into the outside air heat exchanger 30 in a liquid state of low temperature and low pressure through the second expansion valve 221. The outside air heat exchanger (30) absorbs the heat of the outside air, changes to a gas of high temperature and low pressure, and is reduced back to the second compressor (210) via the third heating channel (263).

In the heating process as described above, the heating passage 40 passes through the process of transferring the temperature to the first cycle 100 by utilizing the temperature transmitted to the members disposed on the outdoor side by the second cycle 200 and increasing the temperature again. In the end, the heating temperature can be obtained more efficiently.

In addition, Figure 8 is a view showing an example of the cooling of the heating ventilator having a leakage function using a binary cycle heat pump according to an additional concept of the present invention.

In this cooling cycle, the refrigerant members formed in the heating cycle and the heating cycle are utilized again to transfer heat in the reverse direction.

When the compression operation of the second compressor 210 is started in the endothermic cycle, the passage of the cooling cycle may be opened through a predetermined electronic control valve. The second refrigerant in the high temperature and high pressure state compressed by the second compressor 210 flows through the second endothermic flow passage 272 to discharge heat while passing through the outside air heat exchanger 30. In this case, the outside air heat exchanger 30 ) Serves as the condenser of the second refrigerant.

The second refrigerant flowing through the outside air heat exchanger 30 flows into the other side of the heat exchanger 20 in a state of low temperature and low pressure through the third endothermic flow passage 273, and the heat exchanger 20 receives the first cycle ( 100) to transfer the heat from the first refrigerant to the second refrigerant. In other words, it should be noted that the heat exchange unit 20 operates as an evaporator during heating while the heat exchange unit 20 operates as a condenser in the endothermic cycle.

The second refrigerant of the high temperature low pressure state flowing the other side of the heat exchange part 20 is reduced to the second compressor 210 again through the first endothermic flow path 271 and is returned to the second air compressor 210 at the high temperature and high pressure again. Flows into.

When the first compressor 110 of the cooling cycle is operated, the first refrigerant flows through the second branch passage 172 in a state of high temperature and high pressure and is input to one side of the heat exchange unit 20 to transfer heat to the endothermic cycle. The low temperature and high pressure refrigerant output from the heat exchange unit 20 flows through the third branch passage 173 and passes through the first expansion valve 121 to be input to the internal heat exchanger 10 in a low pressure state.

The refrigeration heat exchanger 10 serves to transfer the heat of the room to the first refrigerant in reverse to the heating cycle, so that the refrigeration heat exchanger 10 may function as an evaporator of the first refrigerant.

Thus, the first refrigerant absorbed from the heat exchanger 10 flows through the first branch flow path 171 and is reduced to the first compressor 110 to be discharged into the heat exchanger 20 under high temperature and high pressure. In addition, the efficiency of heat release may be maximized by the endothermic cycle of the second cycle.

Here, looking at the process of heat transfer in the heating ventilator having a leakage function using the binary cycle heat pump of the present invention, the first refrigerant absorbing the heat in the room flows the heat pump of the cooling cycle to the second refrigerant The heat of the second refrigerant is released from the outside heat exchanger 30 to improve the efficiency of cooling.

On the other hand, in a further concept of the present invention, since the heating, cooling, heating, and endothermic cycles are performed together in one cycle, there is a possibility that the low temperature low pressure refrigerant and the high temperature high pressure refrigerant are mixed in some flow paths. This phenomenon may occur at the confluence of the flow paths, and in particular, when mixed into the compressors 110 and 210 and the expansion valves 121 and 221, there is a fear that an impact may occur or a decrease in efficiency of the device.

Therefore, a backflow prevention device may be further provided at the confluence point of the flow paths as described above. The non-return device prevents the reverse flow of the refrigerant to the compressors 110 and 210 or the reverse flow of the refrigerant to the expansion valves 121, 122, 221, and 222, thereby ensuring the efficiency and durability of the operation. Such a backflow prevention device may be composed of a kind of switching valve for selectively opening and closing the flow path, but may also be made of a device that functions as a predetermined buffer and a selection flow path.

9 is a view showing an embodiment of a heating ventilator main body having a leakage function using a binary cycle heat pump of the present invention.

The main body 1000 of the heating ventilation apparatus having a leakage function using a binary cycle heat pump to which the above-described embodiments of the present invention is applied includes a mixing space 1056 and an mixing space 1056 in which indoor and outdoor air are mixed. The outside air inlet 1064 for introducing the outside air, the inside air inlet 1063 for introducing the internal air into the mixing space 1056, and the indoor air for controlling the temperature of the mixed air from the mixing space 1056 and discharging it to the indoor side And a side heat exchanger 1025 and an outdoor side heat exchanger 1026 which heat-exchanges the mixed air from the mixed space 1056 to the outdoor side.

The mixing space 1056 mixes the outside air introduced from the outside air inlet 1064 and the inside air introduced from the inside air inlet 1063, and discharges it to the outside. The above inside air inlet 1063, outside air inlet. The direction and shape in which the portion 1064, the indoor side heat exchanger 1025, and the outdoor side heat exchanger 1026 are disposed are not necessarily limited to those shown in the drawings.

In an embodiment of the present invention, the mixing process 1056 is primarily performed by providing a concept of the mixing space 1056 without directly introducing outdoor air into the indoor air or discharging the indoor air immediately. The advantage is that the difference can be properly adjusted. The control of the amount of carbon dioxide may lead to the adjustment of the pH concentration. Therefore, the mixing control member 1050 may be disposed in the mixing space 1056 to adjust the mixing concept.

The mixing control member 1050 is to control the amount of oxygen and carbon dioxide before it is introduced into the room through the indoor side heat exchanger 1025 by adjusting the amount of outside air and bet introduced into the mixing space (1056).

As an example of the arrangement of the mixing control member 50, the inside air inlet 1063, the outside air inlet 1064, the indoor side heat exchanger 1025, and the outdoor side heat exchanger 1026 are respectively provided at both sides of the mixing space 1056. It may have the shape of an independent compartment formed in the front and rear of the branch, and the mixing space 1056 and the air inlet 1063, outside air inlet 1064, indoor side heat exchanger 1025 and outdoor side heat exchanger Mixing control members capable of adjusting respective inflows or outflows may be individually disposed at the connection portion 1026. In this case, the amount of mixing of the internal and external air can be adjusted, and only in the direction of circulating the indoor air completely, operating only in the direction of discharging the indoor air to the outside, or only introducing the outdoor air completely into the room. Adjustment can be made to operate.

The mixing control member 1050 may be used to control the opening and closing of the various flow paths if the opening and closing of the flow path can be adjusted. The mixing control member 1050 will be described later with reference to FIG.

When defining a direction extending vertically outdoors and indoors in the longitudinal direction, in one embodiment shown in Figure 9 the mixing control member 1050 may be disposed in the transverse direction in the interior of the mixing space (1056).

That is, the mixing control member 1050 may function as a kind of partition wall that partitions the front and rear of the mixing space 1056 when the flow path is completely closed. In this case, the bet introduced from the inside air inlet 1063 is again indoors. The heat exchanger 1025 is reduced by only the temperature control process, and the outside air introduced from the outside air inlet unit 64 is discharged through the outdoor side heat exchange unit 1026 again at the front side of the mixing control member 1050. In addition, when the mixing space 1056 is completely open, the mixing ratio between the outside and the inside may be maximum.

For example, when the concentration of carbon dioxide in the room is increased, it means that the acidity of the room is increased under a predetermined condition, and in order to control this, the outside air may be mixed to perform a function of ventilation, and the mixing control member 1050 described above. By controlling the opening degree of), the amount of carbon dioxide in the room can be controlled.

Meanwhile, in the concept of FIG. 9, the indoor side heat exchanger 1025 and the outdoor side heat exchanger 1026 may include heat exchangers 10 and 30, respectively.

The indoor heat exchanger 10 provided in the indoor side heat exchanger 1025 may control an indoor temperature by absorbing or radiating heat from the air mixed in the mixing space 1056, and the outdoor side heat exchanger 1026. The outside air heat exchanger (30) provided in the heat dissipation or endotherm with the mixed air discharged to the outside during the cooling or heating process can maximize the efficiency of heating and cooling.

That is, when the heating cycle as described above is driven in the internal air heat exchanger 10, the refrigerant inside the low-temperature and low-pressure flows by the endotherm from the mixed air to lower the indoor air, in the outside air heat exchanger (30) By dissipating heat to the mixed air discharged to the outside to lower the temperature of the refrigerant to be able to utilize the temperature in the internal air heat exchanger (10). Therefore, the energy required for the heating and cooling of the heat pump can be reduced.

In particular, when a binary cycle is applied, there is an advantage of utilizing the heat of the inside and outside air which are mixed and discharged, respectively, and when the outside temperature is extremely low during the operation of the heating cycle, by adjusting the opening degree of the mixing control member 1050, the outside air By adjusting the temperature of the side may have the advantage that the initial starting performance can be improved.

10 is a view showing a main body according to another embodiment of a heating ventilation apparatus having a leakage function using a binary cycle heat pump of the present invention.

The heating ventilator according to another embodiment of the present invention includes two or more heat exchangers (10, 30) and blowing means (31, 32), respectively, and the indoor side heat exchange unit disposed in parallel to each other ( 1010 and the outdoor side heat exchanger 1020, and the mixing unit 1059, which is a space interposed between the indoor side heat exchanger 1010 and the outdoor side heat exchanger 1020.

The heat exchanger (10, 30) may be used a variety of heat exchange means, preferably may be made in a manner to control the temperature of the air through the mutual heat exchange between the refrigerant inside and the air flowing to the outside. In addition, as described above, the heat exchanger may maximize efficiency by using a binary cycle of the heat pump.

Blowing means (1031, 1032) may be optionally used in the heating ventilator if the device for generating a flow of air. Two or more of the air blowing means may be arranged to generate flows in opposite directions in the indoor side heat exchanger 1010 and the outdoor side heat exchanger 1020, respectively. That is, the indoor side heat exchanger 1010 allows the mixed air to flow into the indoor side, and the outdoor side heat exchanger 1020 has the function of ventilation while discharging the mixed air to the outdoor side. On the other hand, the blowing means is to provide the power for introducing the outside air and bet into the mixing space.

The mixing unit 1059 has a mixing space 1055 which is a space in which outside air and bet can be mixed inside, and a second mixing control member 1052 is disposed at the outdoor side of the mixing space 1055, and mixing The first mixing control member 1051 may be disposed at an indoor side of the space 1055.

As described above, the mixing control members 1051 and 1052 function to open and close a predetermined flow path or adjust the opening degree, when the second mixing control member 1052 and the first mixing control member 1051 are completely opened. In the outdoor air inlet 1062, the outdoor air introduced from the outdoor side and the outdoor air introduced from the indoor side to the internal air inlet 1061 may be completely introduced into the mixing space 1055.

In addition, when the first mixing control member 1051 is opened and the second mixing control member 1052 is closed, inflow of outside air to the mixing space 1055 may be blocked, and only indoor air may be circulated.

Therefore, the air flowing into the indoor side heat exchanger 1010 and the outdoor side heat exchanger 1020 is made of mixed air provided from the mixed space 1055.

As shown in the figure, the heating ventilator having a leakage function using the two-cycle heat pump of the present invention is a mixing space 1055 for mixing the outdoor air and indoor air from the outside, from the mixing space 1055 A first compartment 1041 having a temperature controlled as the mixed air flows into the room, a second compartment 1042 having a temperature controlled as the mixed air is discharged to the outside, and disposed inside the first compartment 1041 and mixed with each other. Inner air heat exchanger 10 which primarily exchanges air with air is disposed inside the first compartment 1041 and is disposed outside the second compartment 1042 and the suction side blowing means 1031 for introducing mixed air into the room. And an outside air heat exchanger 30 for exchanging heat with the mixed air, an exhaust side blowing means 1032 disposed outside the second compartment 1042 and discharging the mixed air to the outside, and the front and rear sides of the mixed space 1055. To adjust the amount of bet and outside air The first comprises mixing the control member 1051 and second mixing control member 1052 to.

In addition, the suction side blowing means 1031 may be disposed at the innermost side of the first compartment 1041, and the discharge side blowing means 1032 may be disposed at the outermost side of the second compartment 1042. The means 1031 and 1032 have the advantage of more efficiently exchanging heat between the refrigerant flowing inside and the air flowing on the outer surface of the heat exchangers 10 and 30 while generating a flow of air.

The first compartment 1041, the second compartment 1042, and the mixing space 1055 may be arranged to be spaced apart from each other by a predetermined interval. However, the first compartment 1041, the second compartment 1042, and the mixing space 1055 may be arranged as one module in consideration of the arrangement state. That is, the first compartment 1041, the second compartment 1042, and the mixing space 1055 are formed adjacent to the inside of the housing 1040 forming the exterior, and arranged in parallel to each other makes the members more compact. There is an advantage to deploy.

In detail, the housing 1040 has a hollow shape through which the front and rear sides are penetrated. Preferably, the housing 1040 accurately and spatially partitions the first compartment 1041, the mixing space 1055, and the second compartment 1042. For this purpose, the cross section may be formed in a rectangular shape. The first compartment 1041, the mixing space 1055, and the second compartment 1042 each have a rectangular parallelepiped shape and are sequentially disposed in both lateral directions. The first compartment 1041 and the second compartment ( It is preferable that the width of the mixing space 1055 is smaller than the width of 1042 in view of the flow of air flow and the adjustment of the amount of air by the mixing control member.

The first compartment 1041, the mixing space 1055, and the second compartment 1042 may be divided by a pair of partitions that partition the space from side to side in the housing 1040.

On the other hand, the mixing unit 1059 may have at least four openings for the path of the outflowing and outgoing air flowing into the mixing space, in the drawing, only the outside air inlet 1062 and the inside air inlet 1061 are shown. And, it was described that the mixing control member is disposed only on the inlet side, respectively. However, the mixing control member may be additionally disposed as an outlet of the mixing space, that is, the communication portion of the mixing portion 1059 and the first compartment 1041 and the second compartment 1042 as an adjustment member of the flow rate. In this case, it may have an advantage of completely controlling the amount of inflow or outflow air.

As shown in FIG. 10, the partition wall (not shown) is formed of two rectangular-shaped plates that divide the space inside the housing 1040 into three, and thus, the first compartment 1041 and the mixing space ( 1055 and the second compartment 1042 may form an approximately rectangular parallelepiped space. However, the shape of the housing 1040 and the arrangement or the shape of the partition wall are not necessarily limited thereto.

According to the arrangement, the outside air inlet 1062 and the inside air inlet 1061 of the mixing unit 1059 respectively introduce the outside and the inside into the mixing space 1055, and the inflow amount is respectively the second mixing control member. 1052 and the first mixing control member 1051 can be adjusted. In the internal air heat exchanger 10 disposed in the first compartment 1041, the temperature of the mixed air from the mixing space 1055 is controlled, and in the outdoor air heat exchanger 30 disposed in the second compartment 1042, mixed air. By absorbing or releasing the heat of the waste heat can be recovered. Here, waste heat may be understood to include both positive and negative temperatures. That is, while the heating cycle is operated, the internal air heat exchanger 10 operates as a condenser to increase the temperature of the mixed air and introduces it into the room, while the outdoor air heat exchanger 30 operates as an evaporator, as in the case of the warming cycle described above. It can absorb the heat of the outside or the air of the indoor air discharged. According to this concept, waste heat that is undesirably discarded to the outside can be utilized to construct a cycle of heating again.
