2. Description of the Related Art In recent years, various attempts have been made to combine heating and air-conditioning devices, particularly heat pumps, with ventilation devices in buildings.

The ventilator is operated in such a manner that the contaminated indoor air is discharged to the outside using a blower, the outdoor air is introduced into the room, or the indoor air is filtered and recirculated. Such a ventilator is intended to exchange indoor air or indoor air without changing the room temperature to maintain a clean state of the indoor air. Therefore, the air exchange rate or the amount of air exchange per unit time greatly changes the room temperature Should be limited.

Particularly, in winter when indoor heating takes place, the demand for such functions is further increased. However, in the case of such a ventilator, there is a limit to maintaining the indoor temperature due to structural functional limitations.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an indoor / outdoor mixing chamber of an air conditioner of the present invention will be described in detail with reference to the accompanying drawings.

2 and 3 are views showing a cooling / heating ventilator to which the mixing chamber of the present invention is applied.

The cooling / heating ventilator 1000 to which the mixing chamber of the present invention is coupled basically comprises a suction unit 4000 for sucking indoor and outdoor air, a mixing chamber 3200 for mixing indoor and outdoor air, A mixer 3000 having an evaporator 3110 and a condenser 3120 installed in the evaporator 3110 and a heat exchanger 3120 for exchanging heat with the mixed air; And a flow separator 2000 for separating and discharging the fluid.

Referring to the state of FIG. 2, the front means the indoor side. Harmonized air can be introduced into the room through the opening of the discharge part formed in the flow separation part 2000. Also, the discharge port 2600 disposed opposite to the opening side discharges the unselected cool air or warm air to the outdoor side, and the discharge port 2600 can be connected to the outdoor through the predetermined pipeline.

The evaporator 3110 and the condenser 3120 may be connected to a refrigerant processing apparatus such as a compressor through a predetermined refrigerant passage. The evaporator 3110 and the condenser 3120 may form a single cooling / In order to maximize the efficiency, a two-cycle cycle may be constructed. The operation of the refrigerant will be described later.

In the concept of the present invention, the evaporator 3110 and the condenser 3120 are both provided on the indoor side and the flow is selectively controlled to the indoor / outdoor side through the flow separation unit 2000 It should be noted that there are differences that can be made.

Here, the flow separating unit 2000 can selectively flow cool air and warm air through the predetermined damper, respectively. The 'selective' means that the total flow of cool air and warm air is transmitted to one direction But it should be understood that the present invention encompasses a case in which a flow amount enough to control the indoor temperature is supplied even if some mixed amount exists.

The flow separation part 2000, the mixing part 3000, and the suction part 4000 may be formed so as to communicate with each other so as to form a predetermined flow path therebetween, and may be spatially separated from each other. Preferably, The mixing unit 3000, and the suction unit 4000 may be sequentially arranged from the inlet side to the outlet side. However, it is needless to say that this arrangement relationship can be made selectively.

The mixing section 3000 and the mixing section 3000 are partitioned by an upper plate section 1300 in which a predetermined flow passage is formed and the mixing section 3000 and the suction section 4000 are separated by an intermediate plate section 1200 Can be partitioned. Since the air flowing through the evaporator 3110 and the condenser 3120 flows separately from the upper plate 1300, the upper plate 1300 has a separate communication path and has a coupling relation with the flow separator 2000. Will be described later. Here, the upper plate 1300 can be understood as a constitution of the mixing chamber 3200 to be described later.

The main body 1100 includes a bracket for supporting each member and a main body 1100 for supporting the main body 1100. The main body 1100 includes a main body 1100, And may include a housing having an appearance.

The suction unit 4000 may include an outside air inlet 4110 capable of sucking air on the outdoor side and an indoor air inlet (not shown) capable of sucking air on the inside of the room as described above, A predetermined filter for filtering the air to be sucked may be provided. In the example of FIG. 2, a filter unit 4100 is provided in the suction unit 4000 on the side of the outside air suction port 4110.

The flow separation unit 2000 may be divided into three chambers divided in the left and right direction and includes a first chamber 2100 through which cool air from the evaporator 3110 flows and a second chamber 2100 through which the warm air from the condenser 3120 flows And a discharge unit having a second chamber 2200 and a damper unit 2500 for selectively flowing warm and cool air from the first chamber 2100 and the second chamber 2200 to the indoor and outdoor sides.

The discharge portion can be divided into an upper discharge portion 2300 and a lower discharge portion 2400 which are upper and lower spaces through a predetermined partition wall 2310 partitioning the upper and lower spaces, As shown in FIG.

The upper discharge portion 2300 and the lower discharge portion 2400 may be formed as a single space. Even in this case, the damper portion 2500 can selectively introduce cold air and warm air into the room.

Considering the difference in specific gravity according to the temperature of the air, when cold air heat-exchanged from the evaporator 3110 flows into the first chamber 2100, the refrigerant flows to the lower discharge portion 2400 provided below the discharge portion, 3120) flows to the upper discharge portion 2300 provided on the upper side of the discharge portion when the warmed heat exchanged from the second chamber 2220 flows into the second chamber 2200.

Each of the first chamber 2100 and the second chamber 2200 may include a fan unit for flowing a flow from the mixing unit 3000 to the discharge unit through a predetermined discharge port. Will be described in detail.

4 is a perspective view illustrating a flow separation unit of the cooling / heating ventilator to which the mixing chamber of the present invention is applied.

As described above, the flow separation unit 2000 includes the first chamber 2100, the second chamber 2200, and the first and second chambers 2100 and 2200, And a discharging portion for separating and discharging.

The first chamber 2100 and the second chamber 2200 may include a first fan portion 2110 and a second fan portion 2210. The fan portions 2110 and 2210 may be formed in various forms of flow forming Means can be applied.

The second fan unit 2210 includes a second discharge port 2211 and a second discharge port 2211. The second discharge port 2211 and the second discharge port 2211 are connected to the second fan unit 2210, , And a second inlet (2212) formed toward the condenser (3120). Since the configuration of the second fan unit 2210 can be applied to the first fan unit 2110, a duplicate description will be omitted.

The discharge port is formed so as to be directed to the discharging portion. The discharging portion may be formed as a single unit, or may be formed of the upper discharging portion 2300 and the lower discharging portion 2400, which are two layers as described above.

In order to control the flow from the discharge ports formed on both sides, a damper unit 2500 is provided in the discharge unit. The damper unit 2500 operates the blade by a predetermined driving unit as will be described later, Respectively.

For example, when cool air flows into the indoor space, both ends of the blades may be adjacent to or close to the discharge port so that the outdoor air can be discharged through the discharge port 2600 .

The discharge portion is separated into the upper discharge portion 2300 and the lower discharge portion 2400 by the partition wall portion 2310 and the discharge port of the first chamber 2100 is communicated with the lower discharge portion 2400, The discharge port of the chamber 2200 can communicate with the upper discharge portion 2300. In this case, the upper discharge portion 2300 and the lower discharge portion 2400 may have separate blades, and the plurality of blades may be interlocked with each other.

FIG. 5 shows the overall flow of a cooling / heating ventilator equipped with a mixing chamber according to the present invention.

When the outside air a and the inside air b are sucked and flow upward from the inlet formed at the front and rear sides of the suction unit 4000, And flows into the mixing chamber 3200 to be mixed.

The mixing chamber 3200 has a predetermined flow path formed on both sides thereof and communicates with the evaporator 3110 and the condenser 3120, respectively. The evaporator 3110 and the condenser 3120 form a part of a cooling / heating cycle in which the refrigerant flows, and heat exchange with the mixed air is performed through an area in contact with the air.

The evaporator-side flow c that has flowed on the evaporator 3110 side flows through the first chamber 2100 and the mixing chamber 3200 into the first chamber 2100 through the first inlet (not shown) And flows into the discharge chamber through the first chamber 2100 and the first discharge port communicating with the first chamber 2100 and the lower discharge port 2400. [

When the damper unit 2500 is operated to select the cool air toward the indoor side, the cool air is formed into the indoor side flow g and flows into the room.

The condenser-side flow d flowing in the condenser 3120 side causes the second chamber 2200 and the mixing chamber 3200 to communicate with each other through the second inlet 2212 in the interior of the second chamber 2200, 2210 and flows into the discharge chamber through the second chamber 2200 and the second discharge port 2211 that communicates with the discharge chamber, that is, the second chamber 2200 and the upper discharge port 2300.

When the cold air is selected as described above, the warm air is formed in the outdoor side flow h and is discharged to the discharge port 2600.

6 is a conceptual diagram showing the operation of the damper unit in the cooling / heating ventilator described above.

5, the evaporator-side flow c flowing into the first chamber 2100 flows into the discharge portion through the first discharge port 2111 and is discharged to the discharge portion depending on the arrangement state of the damper portion 2500 On the basis of the city condition, the flow from the left side is guided to the front interior side by the progress.

The flow d on the condenser side flowing into the second chamber 2200 flows into the discharge portion through the second discharge port 2211 and flows toward the discharge port 2600 on the rear side as the flow proceeds from the right side by the damper portion 2500 .

This arrangement state can also be applied to a case where the discharge port is formed as a single space or divided into two or more spaces.

Cooling and warming can be selected by the rotation of the blades of the damper part 2500. The size and shape of the blade 2511 can be formed corresponding to the size of the discharge port.

That is, at least one of the blades is preferably disposed at the other end of the second discharge port 2211, which is the same as or more forward than the front end of the second discharge port 2211 when one end is disposed at the rear end of the first discharge port 2111.

In order to control the undesirable mixing of the flow due to the rotation of the blades, the sidewalls of the discharge portion in which the discharge ports are disposed, i.e., the inner wall of the first chamber 2100 and the second chamber 2200, As shown in FIG. However, it should be noted that, in the case of the flow of air, it is not necessary to necessarily perform sealing in consideration of the fact that some may be mixed.

FIG. 7 is a perspective view showing an upper plate portion of the inner / outer mixing chamber of the cooling / heating ventilator according to the present invention.

As described above, the upper plate portion 1300 arranged to partition the mixing portion 3000 and the flow separation portion 2000 separates the cool air and the warm air and flows into the first chamber 2100 and the second chamber 2200, respectively, A predetermined communication hole is provided.

To this end, the upper plate portion 1300 has a substantially plate shape, and a first opening portion 1301 is formed at a portion corresponding to the first chamber 2100, more precisely at a portion corresponding to an inlet of the first pan portion 2110 And a second opening 1302 is formed at a portion corresponding to the inlet of the second pan portion 2210. [

These openings flow into the mixing chamber 3200 in a state where the indoor air and the outdoor air are mixed and function to separate the cool air and the warm air passing through the evaporator 3110 and the condenser 3120, respectively.

In addition, the upper plate 1300 functions as a supporting portion capable of supporting the fan portion on both sides of the upper surface. In this case, the rigidity of the plate shape itself may cause a problem in supporting the fan portion. Particularly, when a high-capacity fan is adopted as the configuration of the fan portion, a problem of durability may arise in supporting the size and the load.

In order to compensate for this, it is preferable that a reinforcing portion 1305 is additionally disposed on the opening side.

The reinforcing portion 1305 is formed in a predetermined steel rod or hollow pillar shape and is preferably arranged in plural so as to cross the first opening portion 1301 and the second opening portion 1302 side, but is not limited thereto .

The upper plate 1300 preferably has a structure in which a part of the damper unit 2500 can be inserted through the upper plate 1300 to improve spatial efficiency. To this end, a third opening 1303, through which a part of the damper unit 2500 can be inserted, may be formed on the center side of the upper plate part 1300.

The third opening 1303 receives the driving part of the damper part 2500 on the inner circumferential side as described later.

The evaporator 3110 and the condenser 3120 are disposed below the upper plate portion 1300. The lower portion of the condenser 3120 can be supported by the mixing chamber 3200, An additional configuration capable of supporting the evaporator 3110 and the top of the condenser 3120 at the bottom of the condenser 3120 can be further disposed.

Since the lower end of the evaporator 3110 and the condenser 3120 are spaced apart from each other by a maximum distance and the upper ends of the evaporator 3110 and the condenser 3120 are disposed adjacent to each other, And an upper bracket 1310 protruding in a triangular prism shape.

The upper bracket 1310 is formed in a triangular prism shape that is disposed at the bottom surface of the upper plate portion 1300 in the fore and aft direction and a portion of the damper portion 2500 disposed through the third opening portion 1303 can be accommodated The function as the accommodation space can also be performed.

8 is an exploded perspective view showing an inner / outer mixing chamber of the cooling / heating ventilator of the present invention.

The mixing section 3000 can be divided into three spaces. The mixing section 3000 includes a mixing chamber 3200 disposed at the bottom, an evaporator flow section in which the evaporator 3110 is disposed at one side and the evaporator-side flow (c) And the condenser 3120 is disposed on the other side and can be partitioned into a condenser flow portion in which the condenser side flow d is formed.

Here, the mixing chamber 3200 may be understood as a concept of forming a mixing space before the indoor air and the outdoor air flow in from the lower side to flow through the evaporator 3110 and the condenser 3120. However, in the present invention, 3110 and the condenser 3120 are arranged to be guided upward through the upper plate portion 1300. As shown in Fig.

The mixing chamber 3200 may have a shape that forms a part of a substantially isosceles triangle or an isosceles triangle when viewed from the front side, and preferably has a shape symmetrical to the front and rear sides. The mixing chamber 3200 may include a front plate portion 3211 and a rear plate portion 3212. The front plate portion 3211 and the rear plate portion 3212 may include an evaporator 3110 and a condenser 3120 ).

The front plate portion 3211 and the rear plate portion 3212 form a mixing space in which the inside air and the outside air can be mixed.

As described above, both sides of the mixing chamber 3200 are disposed such that the evaporator 3110 and the condenser 3120 are opposed to each other. Such an angle of inclination can be selectively performed, but the optimum air flowability and space utilization Is preferably formed at an angle of 45 degrees.

The first casing 3310 and the second casing 3410 are disposed at both sides of the mixing chamber 3200 so as to accommodate the evaporator 3110 and the condenser 3120 while forming an outer appearance.

The first support portion 3320 and the second support portion 3420 may be disposed on the lower end of the first casing 3310 and the second casing 3410. The first support portion 3320 The second support portion 3420 may be formed with a first support surface portion 3321 and a second support surface portion 3421 which are inclined downward to the inner circumferential side and capable of supporting the evaporator 3110 and the lower end side of the condenser 3120, .

The first support surface portion 3321 and the second support surface portion 3421 may be formed by a plate material method bent from the first support portion 3320 and the second support portion 3420 to the inner circumferential side, And from the second casing 3410 to the inner circumferential side. The angle between the first support surface portion 3321 and the second support surface portion 3421 may correspond to the angle of the top surface of the mixing chamber 3200 so that the evaporator 3110 and the condenser 3120 are substantially parallel to the front surface In the case of a rectangular shape, it is preferably formed at an angle of 45 degrees.

The bottom surface of the evaporator 3110 is supported by the first supporting surface portion 3321 and one side is supported by the upper surface side of the mixing chamber 3200 and the upper surface is supported by the upper side bracket 1310, So that a firm fixation can be achieved.

The bottom surface of the condenser 3120 is supported by the second support surface portion 3421 and one side is supported on the upper surface side of the mixing chamber 3200 and the upper surface is formed on the other side of the lower side of the upper bracket 1310.

The evaporator 3110 and the condenser 3120 can be formed as a heat exchanger for exchanging heat to form cold air and warm air. The evaporator 3110 and the condenser 3120 form a part of a cooling / can do.

In this case, the evaporator 3110 and the condenser 3120 may be connected to a single compressor to form a single cycle. For example, refrigerant flowing from the compressor that compresses the refrigerant to a high- The refrigerant is condensed at a middle temperature and a high pressure, and the refrigerant decompressed through the expansion valve is evaporated in the evaporator 3110, and the refrigerant is heat-exchanged with the mixed air, and the mixed air that is heat-exchanged with the condenser can generate warmth.

However, in the case of such a single cycle, there is a possibility that the efficiency at the time of operating the refrigerant is lowered and it takes a long time to reach the desired temperature. In order to solve this problem, in the additional concept of the present invention, And the condenser 3120 are provided in separate cycles will be described.

The cooling / heating cycle of the indoor / outdoor mixing chamber of the cooling / heating ventilator of the present invention includes an evaporator 3110 disposed on a path where the mixed air flows to the first chamber 2100 and performing heat exchange with the evaporator 3110, A second cycle for transferring heat to the first cycle through a predetermined heat exchange unit, and a second cycle for forming a part of the flow path of the second cycle, And a condenser 3120 arranged on a path through which the mixed air flows into the second chamber 2200 to perform heat exchange.

As described later, the heat of the mixed air absorbed in the second cycle during the operation of the cooling and heating ventilator 1000 is transferred to the first cycle through the heat exchanger as described later, in the first cycle and the second cycle, And transferring the heat of the refrigerant heated in the first cycle to the mixed air through the evaporator 3110. [

Here, the first cycle and the second cycle are each a modular system in which independent flows are formed, the refrigerant circulating in the first cycle is defined as the first refrigerant, and the refrigerant circulating in the second cycle is defined as the second refrigerant . The refrigerant circulating in the first cycle and the second cycle functions as a heat pump in a cycle in which a predetermined flow is performed while compressing, expanding, and performing heat exchange while moving along a predetermined flow path.

In the concept of the present invention, the first cycle functions as a cooling function, and the second cycle functions as a low-temperature cycle for absorbing the heat of the first cycle. Conversely, in the second cycle, One cycle functions as a heating cycle for transferring heat.

That is, in the basic concept of the present invention, the dual cycle of the first cycle and the second cycle operates independently, thereby providing a system in which the efficiency of cooling and heating is maximized as a simple method. The first cycle and the second cycle may each include a compressor and an expansion valve.

Therefore, unlike the case of a single cycle of the related art, there is an advantage that the efficiency of cooling and heating is further improved even when the outside air temperature is high or low. Particularly, it should be noted that in the ventilator, the problem that the heating efficiency is rapidly lowered due to the air circulation and the surrounding environment of the heat exchanger is solved.

The heat exchanger is preferably a plate type heat exchanger in consideration of heat transfer efficiency between refrigerants, but is not limited thereto. The evaporator 3110 and the condenser 3120 mean various types of heat exchange pipes such as a dry evaporator, a monolithic evaporator, a half-liquid evaporator, a refrigerant liquid forced circulation evaporator, and the like, .

According to the concept of the present invention, according to the indoor / outdoor mixing chamber of the cooling / heating ventilator, the speed of rising and falling of the room temperature can be drastically increased and the power consumed can be remarkably reduced, thereby maximizing the efficiency of the cooling / There is an effect.

In addition, since the volume of the entire module is small, the space utilization can be improved, and the outdoor unit is omitted, so that the advantages can be further maximized, the operation of the cooling and heating can be conveniently performed, and the convenience of temperature control can be improved.

In the foregoing, the present invention has been described in detail based on the embodiments and the accompanying drawings.
