The present invention relates to an air conditioner and a control method therefor.

Generally, a heat exchanger can be used as a condenser or an evaporator in a refrigeration cycle apparatus comprising a compressor, a condenser, an expansion mechanism, and an evaporator.

The heat exchanger is installed in a vehicle, a refrigerator, or the like to heat-exchange refrigerant with air.

The heat exchanger can be classified into a fin tube type heat exchanger, a microchannel type heat exchanger, and the like depending on the structure.

The fin-tube type heat exchanger is made of copper material, and the micro-channel type heat exchanger is made of aluminum material.

The micro channel type heat exchanger is more efficient than the fin tube type heat exchanger because a minute flow path is formed inside.

Since the finned tube heat exchanger is manufactured by welding the fin and the tube, the micro channel type heat exchanger is manufactured through the brazing, which is disadvantageous in initial investment cost.

Particularly, since the finned tube heat exchanger is easy to manufacture, it is easy to manufacture the heat exchanger in two rows, but the microchannel heat exchanger is manufactured in a furnace.

1 is a perspective view of a microchannel-type heat exchanger according to the prior art.

As shown, a microchannel-type heat exchanger according to the related art comprises a first column 1 and a second column 2, and a header (not shown) connecting the first column 1 and the second column 2 3 are disposed.

The header (3) provides a flow path for redirecting the refrigerant in the first column (1) to the second column (2).

In the conventional microchannel heat exchanger having two rows, the inlet 4 of the refrigerant is located below the first row 1, and the outlet 5 of the refrigerant is located below the second row 2.

In particular, a plurality of the inlets (4) are formed, and the refrigerant is supplied to the inside of the first column (1) through a plurality of flow paths.

In the first column 1, the refrigerant flows upward from the lower side, and flows from the upper side to the lower side after passing through the header 3 in the second column 2. [

One of the ejection openings 5 is disposed.

That is, the fluid having passed through the first row 1 is collected at the discharge port 5 after being merged somewhere in the second row 2.

The microchannel-type heat exchanger according to the related art has been operated only as a condenser or an evaporator, even though it is composed of a plurality of columns.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

The microchannel heat exchanger according to the first embodiment will be described with reference to FIGS. 2 to 5. FIG.

The air conditioner according to the present embodiment includes a compressor 10 for compressing a refrigerant and a hybrid module 20 for supplying refrigerant from the compressor 10 to condense, expand and evaporate.

The air conditioner may include a blowing fan (11) for flowing air to the hybrid module (20).

The hybrid module 20 according to the present embodiment integrates a condenser, an evaporator, and an expansion mechanism that constitute a refrigeration cycle of a refrigerant.

The hybrid module 20 includes a first heat exchange unit 30 that is heat-exchanged with air, a second heat exchange unit 40 that is stacked on the first heat exchange unit 30 and performs heat exchange with air, And an expansion mechanism (21) arranged between the first heat exchanger (30), the second heat exchanger (40) or the first heat exchanger (30) and the second heat exchanger (40) to expand the refrigerant.

Unlike the present embodiment, the hybrid module 20 may be stacked with two or more heat exchangers.

The first heat exchanging part (30) and the second heat exchanging part (40) are microchannel type heat exchangers.

The first heat exchanging part (30) and the second heat exchanging part (40) are made of aluminum material.

The expansion mechanism 21 may be of various types such as an electronic expansion valve (eev), a Bi-flow valve, or a capillary tube.

An accumulator (not shown) may be installed between the second heat exchanger 40 and the compressor 10. The accumulator stores the liquid refrigerant and supplies only the gas refrigerant to the compressor (10).

The first heat exchanging part 30 includes a plurality of flat tubes 50 having a plurality of flow paths formed therein, a fin 60 connecting the flat tubes 50 to conduct heat, A plurality of flat tubes connected to one side of the plurality of flat tubes and connected to one side of the plurality of flat tubes, A first upper header 80 communicating with the other side of the first lower header 70 or the first upper header 80 and flowing through the first lower header 70 or the first upper header 80, And includes a baffle 90 for partitioning.

In the inside of the flat tube 50, a flow path is formed through which the coolant flows so as to extend in the longitudinal direction.

The flat tubes 50 are arranged vertically and a plurality of flat tubes 50 are stacked in the left and right direction.

A plurality of flow paths are formed in the flat tube 50.

The left side of the flat tube 50 is inserted into and communicated with the first lower header 70.

The right side of the flat tube 50 is inserted into and communicated with the first upper header 80.

The fin (60) is formed by bending, and connects two flat tubes (50) stacked to conduct heat.

The baffle 90 may be installed anywhere in the first lower header 70 or the first upper header 80. In this embodiment, the baffle 90 is installed in the first lower header 70 and the first upper header 80, respectively.

The baffle 90 includes a first baffle 90a installed in the first lower header 70, a second baffle 90b installed in the first upper header 80, And a third baffle 90c to be installed.

The baffle 90 divides the inside of the lower header 70 and the upper header 80 in the left-right direction.

The second baffle 90b divides the inside of the first upper header 80 into two 1-1 spaces 91 and 1-2 spaces 92.

The second baffle 90b divides the first upper header 80 in the left-right direction.

The direction of the refrigerant flowing on the left side of the baffle 90 and the direction of the refrigerant flowing on the right side are opposite to each other.

The right space of the upper header 80 separated by the baffle 90 is defined as a 1-1 space 91 and the left space of the upper header 80 divided by the baffle 90 is defined as 1-2 Space 92 as shown in FIG.

The flat tubes 50 disposed on the right side of the baffle 90 are defined as one group 51 and the flat tubes 50 disposed on the left side of the baffle 90 are defined as the two groups 52. [

The inside of the first lower header 70 is partitioned into a 2-1 space 93 and a 2-2 space 94 by a first baffle 90a.

The flat tubes 50 of the first group 51 and the flat tubes 50 of the second group 52 are separated from each other by the first baffle 90a and the second baffle 90b.

A connection pipe 25 is provided to flow the refrigerant from the first group 51 to the second group 52 and the expansion pipe 21 is installed in the connection pipe 25.

In the present embodiment, the connection pipe 25 is installed in the first upper header 80.

Unlike the present embodiment, the connection pipe 25 may be installed in the first lower header 70.

One end 25a of the connection pipe 25 is connected to the 1-1 space 91 and the other end 25b of the connection pipe 25 is connected to the 1-2 space 92 in this embodiment.

In this embodiment, an expansion mechanism (21) is installed in the middle of the connection pipe (25). The expansion mechanism 21 may be directly connected to the 1-1 space 91 or 1-2 space 92, unlike the present embodiment.

In order to supply the refrigerant from the first heat exchanging part (30) to the first group (51), the inflow pipe is located on the opposite side of the connecting pipe (25).

Thus, in this embodiment, the inlet pipe 22 is connected to the first lower header 70.

More precisely, the inlet pipe 22 is connected to the 2-1 space 93.

Therefore, the refrigerant supplied from the compressor 10 through the inlet pipe 22 flows into the first group 51, the first space 51, the second space 51, the second space 51, -> expansion mechanism (21) -> 1-2 space (92) -> 2 groups (52) -> 2-2 space (94)

Here, in the process of passing through the first group 51, the refrigerant is heat-exchanged with air and condensed.

The refrigerant expands while passing through the expansion mechanism (21).

And the refrigerant expanded while passing through the second group 52 is evaporated while exchanging heat with air.

That is, in the flat tube 50 of the first heat exchanger 30, the refrigerant is condensed, and the remaining refrigerant is evaporated.

The refrigerant in the 2-2 space 94 flows to the second heat exchanging part 40 and the refrigerant is continuously evaporated while passing through the second heat exchanging part 40.

The second heat exchanging part (40) has a structure similar to that of the first heat exchanging part (30).

The second heat exchanger 40 includes a plurality of flat tubes 50 connecting the second upper header 81, the second lower header 71, the second upper header 81 and the second lower header 71, And a pin 60 connecting the flat tubes 50 to conduct heat.

The flat tube 50 is divided into two groups of three (53) and four (54) groups.

In order to distinguish the groups 53 and 54, a third bellow 90c is provided in the second lower header 71. The third baffle 90c divides the second lower header 71 in the left-right direction.

The third baffle 90c separates the second lower header 71 into a 3-1 space 95 and a 3-2 space 96.

Four spaces 97 are formed in the second upper header 81.

In the present embodiment, the baffle is not provided in the second upper header 81.

When the second heat exchanging part 40 is divided into three or more groups, the second upper header 81 may be provided with a baffle, unlike the present embodiment.

A discharge pipe (24) is connected to the 3-2 space (96).

The left side of the third baffle 90c is divided into three groups 53, and the right side is defined as four groups.

The 3-1 space 95 of the second heat exchanging part 40 and the 2-2 space 94 of the first heat exchanging part 30 are communicated to allow the refrigerant to flow.

The 2-2 space 94 and the 3-1 space 95 may be entirely communicated or may be connected through a pipe.

The first upper header 80 and the second upper header 81 may be integrally formed. The first lower header 70 and the second lower header 71 may be integrally formed.

The flat tubes 50 of the first heat exchanging part 30 and the second heat exchanging part 40 are spaced apart from each other even if the upper header 80 or 81 or the lower header 70 are formed as a single component .

In the flow of the refrigerant, the refrigerant in the second-2 space 94 flows into the third group 53, the third space 53, the fourth space 54, the fourth group 54, 3-2 space 96 ", and is heat-exchanged with air and evaporated in the process of flowing.

The refrigerant in the 3-2 space 96 is discharged from the second heat exchanger 40 through the discharge pipe 24 and then flows to the compressor 10.

The blowing fan 11 causes air to flow from the second heat exchanging part 40 to the first heat exchanging part 30. [

Thus, the air is first subjected to heat exchange with the second heat exchange section (40), and then heat exchange with the first heat exchange section (30).

Therefore, in the third group 53 and the fourth group 54 of the second heat exchanging unit 40 operated by the evaporator, evaporation of the refrigerant is more effectively achieved.

The second group 52 of the first heat exchanging unit 30 operated as an evaporator evaporates the refrigerant in a state where the second group 52 is separated by the first baffle 90a and the second baffle 90b.

The first group 51 of the first heat exchanging part 30, which is operated by the condenser, heat-exchanges with the air to condense the refrigerant.

Thus, since the second group 52 and the third group 53, which are operated by the evaporator, are stacked on the left side of the hybrid module 20, cold air is discharged.

On the right side of the hybrid module 20, cool air is discharged because the fourth group 54 operated by the evaporator and the first group 51 operated by the condenser are stacked.

That is, air having different temperatures is discharged from the left and right sides of the hybrid module 20 according to the present embodiment.

Although one blowing fan 11 is provided in this embodiment, two blowing fans may be installed to generate the respective air flows from the left and right sides.

In this case, the left or right wind speed or air volume can be adjusted according to the user's needs.

In particular, when dehumidification is performed, since the first group 51 operated by the condenser heats the cold air that has passed through the second heat exchanging part 40, it is possible to provide air with a pleasant temperature.

Further, since there are more evaporator-operated groups 52, 53 and 54 among the plurality of groups 51, 52, 53 and 54 and fewer groups 51 operated by the condenser, The dehumidifying capacity can be increased.

Meanwhile, in the present embodiment, when the expansion mechanism 21 is an electronic expansion valve, the amount of opening of the expansion mechanism 21 may be adjusted so that the refrigerant is overheated in the fourth group 54, The condensation heat loss of the first group 51 operated by the condenser can be minimized.

That is, when the opening amount of the refrigerant in the fourth group 54 is controlled to be overheat, the temperature of the refrigerant is lower than that of the second group 52 or the third group 53 even if the fourth group 54 is operated as an evaporator . Therefore, air flowing into the first group 51 through the fourth group 54 is formed at a higher temperature than air flowing into the second group 52 through the third group 53.

Thereby minimizing the loss of heat of condensation in the first group 51 operated by the condenser and regulating the temperature of the air passing through the first group 51.

Thus, the air conditioner according to the present embodiment can adjust the opening amount of the expansion mechanism 21 to regulate the temperature of the air passing through the group 51 operated by the condenser.

Thus, in the air conditioner according to the present embodiment, the temperature of the first group 51 is not determined by the heat of condensation of the refrigerant, and the temperature of the air passing through the condenser through the control of the superheating degree of the expansion mechanism (21) .

In addition, when separate air outlets are provided on the left and right sides of the air conditioner, winds of different temperatures can be discharged from the left air outlet and the right air outlet.

In the hybrid module 20 according to the present embodiment, since the condenser, the evaporator, and the expansion mechanism are integrally manufactured, the connection of the piping can be minimized during the manufacture of the air conditioner, thereby minimizing the assembly process and installation time There are advantages to be able to.

The definitions of the 1-1 space, the 1-2 space, the 2-1 space, and the 2-2 space are independent of the flow order of the refrigerant, and are only a name for specifying each internal space.

Also, the names of the groups of the flat tubes 50 are independent of the flow order of the refrigerant.

The air conditioner according to the second embodiment will be described with reference to FIG.

The air conditioner according to the second embodiment differs from the first embodiment in that a condensation heat exchanger 26 is provided separately from the hybrid module 20 and a separate expansion mechanism 23 for expanding the refrigerant discharged from the condensation heat exchanger 26 Is installed. In order to distinguish the expansion mechanism 21 of the first embodiment from the expansion mechanism 21 of the first embodiment, in this embodiment, the expansion mechanism 21 provided in the hybrid module 20 is defined as an integral expansion mechanism 21, The mechanism (23) is defined as a separate expansion mechanism (23).

The separating / expanding mechanism (23) is preferably provided with an electronic expansion valve.

In the present embodiment, the separating expansion mechanism 23 can selectively expand or partially expand the condensed refrigerant to the hybrid module 20 without expanding the condensed refrigerant.

The air conditioner according to the present embodiment may be a separate type air conditioner composed of an indoor unit and an outdoor unit.

The condensing heat exchanger 26 is disposed outdoors, and the hybrid module 20 can be disposed indoors.

The flow of the refrigerant is as follows.

First, the refrigerant compressed in the compressor 10 condenses the refrigerant into a liquid state while generating condensation heat in the condensing heat exchanger 26, and the condensed refrigerant passes through the separating expansion mechanism 23.

The separation expansion mechanism (23) can control the state of the refrigerant passing through the opening expansion amount.

For example, when fully opened, the condensed refrigerant is supplied to a first group 51 of the hybrid modules 20 in an unexpanded condensed refrigerant state. The condensed refrigerant in the liquid state supplied to the hybrid module 20 operates in the same manner as in the first embodiment.

As another example, when the separation expansion mechanism 23 expands a certain amount of refrigerant, the expanded refrigerant may be supplied to the first group 51 of the hybrid module 20.

The refrigerant supplied to the first group (51) may be a mixture of the expanded refrigerant and the liquid refrigerant, or may be a refrigerant whose whole amount is expanded.

In the case where only a part of the refrigerant supplied to the first group 51 is expanded refrigerant, the integral expansion mechanism 21 of the hybrid module 20 inflates the remaining liquid refrigerant, and then supplies the expanded refrigerant to the second group 52.

When the refrigerant supplied to the first group 51 is fully expanded refrigerant, the integral expansion mechanism 21 may be fully opened to allow the expanded refrigerant to pass through the two groups 52.

Alternatively, the amount of opening of the integral expansion mechanism (21) may be adjusted to expand the condensed liquid refrigerant again during the movement.

That is, the hybrid module 20 according to the present embodiment may operate all the groups as an evaporator, or only a part as an evaporator.

Since the remaining configuration is the same as that of the first embodiment, the detailed description will be omitted.

The air conditioner according to the third embodiment will be described with reference to Fig. 7 or Fig.

The air conditioner according to the present embodiment is different from the second embodiment in that an integral expansion mechanism 21 is provided between the first heat exchanging part 30 and the second heat exchanging part 40. [

The integral expansion mechanism (21) may be disposed between the headers of the respective heat exchange units (30, 40).

For example, the integral expanding mechanism 21 may be installed between the first upper header 80 and the second upper header 81.

As another example, the integral expansion mechanism 21 may be installed between the first and second low header portions 70 and 71.

The integrated expansion mechanism 21 may be provided between the first upper header 80 and the second lower header 71 or between the first lower header 70 and the second upper header 81.

When the integral expansion mechanism 21 is provided as in the present embodiment, the entire first heat exchange section 30 may be used as a condenser, or the entire first heat exchange section 30 may be used as an evaporator.

In addition, when the amount of opening of the separating / expanding mechanism 23 is adjusted, the temperature of the discharged air can be adjusted by overheating the refrigerant passing through the four groups 54 of the second heat exchanging unit 40.

The air conditioner according to the fourth embodiment will be described with reference to Figs. 9 to 11. Fig.

The air conditioner according to the present embodiment is different from the second embodiment in that a four-way valve 100 is provided between the hybrid module 20 and the separate expansion mechanism 23, and through the heat exchangers 30 and 40 There is a characteristic that the temperature can be controlled independently.

The refrigerant may be flowed from the first heat exchanging part 30 to the second heat exchanging part 40 through the control of the four-way valve 100. In the second heat exchanging part 40, the first heat exchanging part 30 ). ≪ / RTI >

The number of groups operated by the condenser in each of the groups 51, 52, 53 and 54 of the first heat exchanging unit 30 and the second heat exchanging unit 40 through the control of the flow direction of the refrigerant, The number of groups to be operated can be adjusted.

The four-way valve 100 includes a first valve passage 101 connected to the separation expansion mechanism 23, a second valve passage 102 connected to the compressor 10, a second valve passage 102 connected to the first heat exchange section 30, A third valve passage 103 and a fourth valve passage 104 connected to the second heat exchanging section 40.

The controller of the air conditioner controls the four-way valve 100 to control the refrigerant supplied to the first valve passage 101 to flow into the third valve passage 103 or the fourth valve passage 104 .

Therefore, when the refrigerant is supplied from the first valve passage 101 to the third valve passage 103 (see FIG. 10), the refrigerant may flow from the first heat exchanging portion 30 to the second heat exchanging portion 40 have.

Alternatively, when the refrigerant is supplied from the first valve passage 101 to the fourth valve passage 104 (see FIG. 11), the refrigerant flows from the second heat exchanging portion 40 to the first heat exchanging portion 30 .

That is, the air conditioner according to the present embodiment can select the heat exchanging units 30 and 40 through which the refrigerant is first supplied through the four-way valve 100.

First, when refrigerant is firstly supplied to the first heat exchanging part 30 through the control of the four-way valve 100 (hereinafter, referred to as forward direction), the separating / expanding mechanism 23 is fully opened to pass the condensed refrigerant, At least a part of the first heat exchanging part (30) can be operated as a condenser, and the second heat exchanging part (40) can be operated as an evaporator.

In this embodiment, the first group 51 is operated as a condenser, and the second group 52, the third group 53, and the fourth group 54 are operated as an evaporator.

The refrigerant flowing from the first group 51 to the second group 52 can be expanded by adjusting the amount of opening of the integral expansion mechanism 21. [

The amount of opening of the integral expansion mechanism 21 may be controlled to control the refrigerant passing through the four groups 54 to be overheated.

In this case, the air passing through the stacked group 51 and the group 54 passes through the evaporator-condenser in this order, and is discharged at a temperature that the user feels cool.

Since the air passing through the two stacked groups 52 and 53 passes through the evaporator-evaporator, it is discharged at a temperature that the user feels cold.

Therefore, the left and right sides of the hybrid module 20 can discharge air of different temperatures.

Next, the first group 51 may also be operated by the evaporator by adjusting the opening amounts of the separation expansion mechanism 23 and the integral expansion mechanism 21. [

Both of the first and second heat exchanging portions 30 and 40 are operated by the evaporator so that only a part of the refrigerant passing through the first and second heat exchanging portions 30 and 40 is inflated so that the temperature in the first group 51 Can be controlled.

In other words, the temperature of the first group 51 can be more actively controlled by adjusting the opening amounts of the separation expansion mechanism 23 and the integral expansion mechanism 21. [

Next, when the refrigerant is firstly supplied to the second heat exchanging unit 40 through the control of the four-way valve 100 by passing the condensed refrigerant through the open expansion and expansion mechanism 23 (hereinafter referred to as the reverse direction) , At least a part of the second heat exchanging part (40) can be operated as a condenser, and the first heat exchanging part (30) can be operated as an evaporator.

In this embodiment, the refrigerant having passed through the separation expansion mechanism 23 flows in the order of 4 groups 54, 3 groups 53, 2 groups 52 and 1 group 51.

Here, the four groups 54, the third group 53 and the second group 52 are operated as a condenser, and the first group 51 can be operated as an evaporator.

The integral expansion mechanism 21 can expand the refrigerant flowing from the second group 52 to the first group 51. [

Thus, referring to FIG. 11, three of the four groups arranged in the hybrid module 20 are operated as a condenser, and one is operated as an evaporator.

In this case, warm air is discharged from the side where the second and third groups 52 and 53 are laminated, and cool air is discharged from the side where the first and fourth groups 51 and 54 are laminated.

If the outside temperature is low, dehumidification may be carried out while discharging such warm winds.

The temperature of the refrigerant flowing in the reverse direction in the hybrid module 20 can be controlled by adjusting the opening amount of the separation expansion mechanism 23 and the integral expansion mechanism 21. [

For example, when all the refrigerant passing through the separating expansion mechanism 23 is expanded, both the one heat exchanging section 30 and the two heat exchanging section 40 are operated as an evaporator.

In the case of expanding only a part of the refrigerant passing through the separating expansion mechanism 23 and expanding all the remaining condensed refrigerant in the integral expansion mechanism 21, four groups 54, three groups 53 and 2 The temperature of the group 52 can be actively controlled.

That is, when some of the refrigerant is expanded in the separating / expanding mechanism 23, the refrigerant temperature of the four groups 54, the third group 53 and the second group 52 operated as the condenser can be lowered compared with the case where the refrigerant is fully opened .

The temperature of the air discharged from the left side of the hybrid module 20 and the temperature of the air discharged from the right side can be controlled through the control of the separation expansion mechanism 23 and the integral expansion mechanism 21. [

In particular, in the air conditioner in which the four-way valve 100 and the hybrid module 20 are combined as in the present embodiment, intensive cooling in which the implantation is generated in a group of the hybrid module 20 may be performed.

It is also possible to carry out an operation of defrosting the implantation generated in the hybrid module 20 through the control of at least one of the four-way valve 100, the integral expansion mechanism 21 and the separate expansion mechanism 23. [

In addition, the hybrid module 20 may alternatively operate the direction of the refrigerant through the control of the four-way valve 100.

The rest of the configuration is the same as in the second embodiment, and therefore, detailed description thereof will be omitted.

12 to 14, an air conditioner according to a fifth embodiment will be described.

The air conditioner according to the present embodiment is different from the fourth embodiment in that the integral expansion mechanism 21 is disposed between the first heat exchanging portion 30 and the second heat exchanging portion 40. [

More specifically, an integral expansion mechanism 21 is provided between the second group 52 and the third group 53. [

The refrigerant flows from the hybrid module 20 in the normal direction (refrigerant flow from the first heat exchanging portion to the second heat exchanging portion) through the refrigerant passing through the condenser 23 and the control of the four-way valve 100 The first heat exchanging portion 30 can be operated as a condenser and the second heat exchanging portion 30 can be operated as an evaporator. At this time, the integral expansion mechanism (21) expands the refrigerant flowing from the first heat exchange section (30) to the two heat exchange section (40).

Here, it is also possible to control the amount of opening of the separation expansion mechanism 23 and the integral expansion mechanism 21 so as to overheat the refrigerant in the four groups 54.

When the separation expansion mechanism 23 is fully opened, both of the first and second heat exchange units 30 and 40 may be operated as an evaporator.

Next, refrigerant is passed through the separating / expanding mechanism 23 and refrigerant is flowed in the reverse direction (refrigerant flow from the second heat exchanging part to the first heat exchanging part) in the hybrid module 20 through the control of the four-way valve 100 The second heat exchanging part 40 can be operated as a condenser and the first heat exchanging part 30 can be operated as an evaporator.

At this time, the integral expansion mechanism (21) expands the refrigerant flowing from the second heat exchange section (40) to the one heat exchange section (30).

Here, the amount of opening of the separation expansion mechanism 23 and the integral expansion mechanism 21 may be adjusted to control the refrigerant in the first group 51 to be overheated.

The rest of the configuration is the same as that of the above-mentioned four embodiments, and a detailed description thereof will be omitted.
