Detailed Description

First embodiment

(1) Integral structure

Fig. 1 is a schematic diagram for explaining an outline of an air conditioner 10 according to a first embodiment. Fig. 2 is a schematic diagram showing an example of the refrigerant circuit 15 of the air conditioning apparatus 10 in the first embodiment.

In the following description, when a plurality of devices having the same function are described in common, the same reference numerals are attached to the devices for description. Note that, when a single device is described as being distinguished from a plurality of devices having the same function, the subscripts of the english lowercase letters are attached to the description.

In the air conditioner 10, the usage-side unit 20 and the heat source-side unit 30 form a group to constitute the refrigerant circuit 15.

The use-side module 20 has at least a use-side heat exchanger module 21. The use-side heat exchanger module 21 includes at least a heat exchanger and a fan, and exchanges heat with air in the predetermined space R. Then, the use-side module 20 sends the air after heat exchange as conditioned air to the space R directly from the use-side heat exchanger module 21 or through another module. Here, the refrigerant circuit 15 is provided with a use-side stop valve 25 (connection port), and the use-side stop valve 25 (connection port) is detachably connected to the use-side heat exchanger module 21.

In the heat-source-side module 30, the at least one compressor module 40 is separated from the at least one heat-source-side heat exchanger module 50 and connected via the heat-source-side piping 33. The heat source side unit 30 is provided outside the conditioned air sending space R. The heat source-side pipe 33 is provided with a heat source-side shutoff valve 35 (connection port), and the heat source-side shutoff valve 35 (connection port) is detachably connected to the heat source-side heat exchanger module 50.

(2) Detailed structure of heat source side assembly

In the heat source-side unit 30, the casing of the compressor module 40 and the casing of the heat source-side heat exchanger module 50 are formed of different members. Thereby, the compressor module 40 and the heat source side heat exchanger module 50 can be provided separately.

(2-1) compressor Module

The compressor module 40 is provided with at least a compressor 46. For example, the compressor module has a rectangular parallelepiped housing 45 as shown in fig. 4, and houses a compressor 46, a four-way switching valve 47, and the like therein. In addition, in the case where a plurality of compressor modules 40 are connected, at least one compressor module 40a has a first control portion 41.

The first control unit 41 controls each device constituting the refrigerant circuit 15. That is, the first controller 41 controls not only the compressor module 40a having the first controller 41 but also the other compressor module 40b and the heat source side heat exchanger module 50. Specifically, the first control unit 41 transmits control information to the

second control units

42 and 52 described later, thereby controlling the constituent devices of the

modules

40b and 50 having the

second control units

42 and 52. Further, "control information" includes a control target value of a control target (for example, the rotation speed of a fan) set for each constituent device (for example, a fan) in each module.

In the air conditioner 10, at least one compressor module 40a having the first control unit 41 may be provided. Therefore, the other compressor module 40b not having the first controller 41 may or may not be present.

In addition, when the air conditioner 10 includes the compressor module 40b without the first controller 41, the compressor module 40b includes the second controller 42. The second control unit 42 controls the constituent devices of the compressor module 40b based on the control information via the first control unit 41 of the compressor module 40 a.

(2-2) Heat Source side Heat exchanger Module

The heat source side heat exchanger module 50 includes at least a heat exchanger 56, a fan 57, a temperature sensor 58, and an expansion mechanism 59 as constituent devices, and a second control unit 52 (see fig. 2 and 3) for controlling these constituent devices. In the present embodiment, the "expansion mechanism" refers to a mechanism capable of reducing the pressure of the refrigerant, and for example, an expansion valve or a capillary tube corresponds to the expansion mechanism.

The second control unit 52 controls the constituent devices in the heat source side heat exchanger module 50 based on the control information via the first control unit 41 of the compressor module 40. That is, the second control unit 52 controls the control object based on the control information transmitted from the first control unit 41 at any time. The second control unit 52 determines a control value of a predetermined control target so as to achieve the control target value, and controls the control target. That is, the second control unit 52 can control the control target value once, independently of the first control unit 41.

For example, the predetermined control targets for the fan 57 and the expansion mechanism 59 as constituent devices may be the rotation speed of the fan 57 and the opening degree of the expansion mechanism 59, and control may be set for these control targets. In this case, the second control unit 52 controls the rotation speed of the fan 57 and the opening degree of the expansion mechanism 59 based on the detection information of the temperature sensor 58 and the control target value. That is, once the control target value is obtained, the second controller 52 controls the rotation speed of the fan 57 and the opening degree of the expansion mechanism 59 independently of the first controller 41.

Specific examples of the heat source-side heat exchanger module 50 include a first type of heat exchanger module 50s (fig. 5) that blows air upward, a second type of heat exchanger module 50t (fig. 6(a) to 6(c)) that blows air sideways, and a third type of heat exchanger module 50u (fig. 7) that blows air obliquely. In the present embodiment, the heat source-side heat exchanger module 50 is selected from any one or any combination of the first to third types of

heat exchanger modules

50s, 50t, and 50 u. In the present embodiment, one compressor module 40 is connected to a plurality of heat source side heat exchanger modules 50 via the heat source side piping 33. In addition, the heat exchanger module 50t of the second type can be selected from a plurality of modes 50t1, 50t2, 50t3 in correspondence with the arrangement of the fans.

(3) Feature(s)

(3－1)

As described above, in the air conditioner 10 of the present embodiment, the heat source side unit 30 can be divided into the plurality of

modules

40 and 50, and therefore the air conditioner 10 can be introduced optimally in accordance with the appearance, structure, and the like of the building. In particular, since the heat source-side heat exchanger module 50 can be selected from any one or any combination of the first type heat exchanger module 50s that blows air upward, the second type heat exchanger module 50t that blows air sideways, and the third type heat exchanger module 50u, the air conditioning apparatus 10 having an optimum configuration can be introduced in accordance with the design specifications of the building.

For example, depending on the design specifications of a tall building, it may be required to dispose the heat-source-side module 30 on the evacuation floor. In this case, in the air conditioning apparatus 10 according to the present embodiment, the installation area can be reduced by disposing the compressor module 40 separately from the heat source side heat exchanger module 50. That is, in the case where the heat source-side module 30X is provided in a type in which the compressor module and the heat source-side heat exchanger module are not separated (integrated) and air is blown upward, as shown in fig. 8, a guide member 70X for guiding the air blown upward is necessary. Therefore, it is difficult to reduce the installation area. In contrast, in the air conditioning apparatus 10 of the present embodiment, as shown in fig. 9, the installation area can be reduced by using the heat exchanger module 50t of the second type (cross-blow type).

In the air conditioning apparatus according to the present embodiment, for example, short-circuiting can be prevented by disposing the compressor module 40 separately from the heat source side heat exchanger module 50. For example, as shown in fig. 10, by disposing the heat source side heat exchanger module 50 in a place where ventilation is good in the wall surface of a tall building, it is possible to avoid the occurrence of a short circuit, which is a phenomenon in which the air after heat exchange circulates immediately and flows into the heat source side heat exchanger module 50.

For example, in the air conditioning apparatus 10 according to the present embodiment, the compressor module 40 and the heat source side heat exchanger module 50 are disposed separately from each other, thereby reducing noise. For example, as shown in fig. 11, by providing the compressor module 40 in the machine room of a high-rise building, the compressor module 40 as a noise source is separated from a space used by many people, and noise reduction can be achieved.

(3－2)

In the air conditioning apparatus 10 of the present embodiment, a plurality of heat source side

heat exchanger modules

50s, 50t (see fig. 2) are connected to one compressor module 40 via pipes. With this configuration, the heat exchange performance can be optimized according to the installation location.

(3－3)

In the air conditioning apparatus 10 of the present embodiment, at least one compressor module 40a includes a first controller 41, and the first controller 41 controls each device constituting the refrigerant circuit 15. Further, the

second control units

42 and 52 are provided in the

modules

40b and 50 other than the compressor module 40a having the first control unit 41, and the

second control units

42 and 52 control the constituent devices in the

modules

40b and 50 based on the control information via the first control unit 41. With this configuration, the

modules

40b and 50 can be controlled by the first controller 41.

The control information includes a control target value for the control target in the module. The second control unit 52 in the heat source side heat exchanger module 50 other than the compressor module 40a having the first control unit 41 determines a control value of the control target for a predetermined control target so as to achieve the control target value, and controls the control target. With this configuration, the second control unit 52 can control the control target value once, independently of the first control unit 41. Therefore, efficient centralized control of the entire air conditioner 10 can be achieved.

(3－4)

In the air conditioning apparatus 10 of the present embodiment, the heat source-side heat exchanger module 50 includes at least a temperature sensor 58, a fan 57, and an expansion mechanism 59.

The second control unit 52 controls the rotation speed of the fan 57 and the opening degree of the expansion mechanism 59 based on the detection information of the temperature sensor 58 and the control target value. With such a configuration, the second controller 52 can control the rotation speed of the fan 57 and the opening degree of the expansion mechanism 59 independently of the first controller 41 once the control target value is obtained. This can reduce the amount of communication between the compressor module 40 and the heat source side heat exchanger module 50.

(3－5)

In the air conditioning apparatus 10 of the present embodiment, a heat source-side shutoff valve 35 (connection port) to which the heat source-side heat exchanger module 50 is detachably connected is provided in the heat source-side pipe 33. With this configuration, the heat source side heat exchanger module 50 can be disposed at an optimum location.

(3－6)

In the air conditioning apparatus 10 of the present embodiment, a use-side stop valve 25 (connection port) to which the use-side heat exchanger module 21 is detachably connected is provided in the refrigerant circuit. With this configuration, the use-side heat exchanger module 21 can be disposed at an optimum location.

(3－7)

In addition, when the capacity of the heat source side heat exchanger module 50 is insufficient due to an increase in the load on the use side heat exchanger module 21, the heat source side heat exchanger module 50 can be easily added after initial installation. This can significantly reduce installation space, construction time, equipment cost, and the like, as compared with a case where the load is compensated for by another system.

(3－8)

In addition, when it is desired to suppress an increase in the maximum power of the building accompanying an increase in the utilization rate of the building, the amount of power consumption can be reduced by adding the heat source-side heat exchanger module 50. Therefore, the electricity charge can be reduced. In addition, by reducing the maximum power at peak load, it is possible to avoid adding power receiving equipment to the building. Further, there is a possibility that the electricity charge can be reduced according to contract contents different from those contracted with the electric power company.

(3－9)

In addition, in the case where the environment of the installation location of the heat source-side heat exchanger module 50 changes, for example, in the case where another heat source device is installed or an obstacle is installed in the air outlet, the capacity of the use-side heat exchanger module 21 may become insufficient; or the heat exchange efficiency is decreased due to the decrease of the air volume, so that the power consumption of the compressor is increased. In the heating operation, the evaporation temperature of the heat exchanger in the heat source side heat exchanger module 50 may decrease, and frost formation may easily occur, and the heating capacity may become insufficient. Even in such a case, the problem can be solved by moving the heat source side heat exchanger module 50, changing the style of the heat source side heat exchanger module 50 to avoid an obstacle, or by changing the capacity of the heat source side heat exchanger module 50 (increasing the capacity), or by adding the heat source side heat exchanger module 50.

(4) Modification example

(4-1) modification 1A

In the air conditioning apparatus 10 of the present embodiment, there are a plurality of heat source-side heat exchanger modules 50, and the heat source-side heat exchanger module 50 may include at least a different type of heat exchanger module. For example, the heat source side heat exchanger module 50 may select at least one first type of heat exchanger module 50s and at least one second type of heat exchanger module 50 t. Thus, when a plurality of types of

heat exchanger modules

50s and 50t are preferably used, the air conditioning apparatus 10 having the most suitable configuration can be introduced.

(4-2) modification 1B

In the air conditioning apparatus 10 of the present embodiment, as shown in fig. 12, a plurality of

compressor modules

40a and 40b may be present in one refrigerant circuit 15. With this configuration, the heat exchange performance can be optimized according to the installation location.

(4-3) modification 1C

In the air conditioning apparatus 10 of the present embodiment, as shown in fig. 12, modules other than the compressor module 40 and the heat source-side heat exchanger module 50 may be connected to the heat source-side module 30. For example, as shown in fig. 12, an additional compressor module 40b, a switching valve module 60 having a four-way switching valve 47, and a long-pipe corresponding module 61 having a heat exchanger and an expansion mechanism are connected.

(4-4) modification 1D

The first control unit 41 of the air conditioning apparatus 10 according to the present embodiment may transmit status information of all the constituent devices of the refrigerant circuit, etc., which are introduced into the plurality of outdoor unit systems 5a, 5b, and 5c and the use side heat exchanger module 21 (indoor unit), to the management apparatus 1 (referred to as "smart P panel" herein). Thereby, the management apparatus 1 can manage the states of all the constituent devices. In fig. 13, the line connecting the modules means a signal line. In the system shown in fig. 13, information is transmitted via the modules in sequence. The management device 1 has operation control functions such as mode setting, operation and stop, temperature setting, airflow direction setting, airflow volume setting, and schedule setting of the use-side heat exchanger module 21, and can collectively control the use-side heat exchanger modules 21. The management apparatus 1 can be connected to the internet via a router, and can perform data management and operation control at a remote location.

By collecting or storing the operation states, it is possible to grasp the excess or deficiency of the load of the use-side heat exchanger module 21. When the capacity is insufficient for the load, by adding the heat source side heat exchanger module 50 in the manner described in (3-7), it is possible to reduce the installation space, the construction time, the cost, and the like without adding other equipment.

Although fig. 13 describes "64 indoor units can be installed at maximum", this description is merely an example of the number of connected units of the use-side heat exchanger module 21 (indoor unit). This is merely an example, and the air conditioning apparatus 10 according to the present embodiment may include 64 or more use side heat exchanger modules 21.

Second embodiment

(5) Detailed structure of heat source side assembly

In the following, the same portions as those described above are denoted by the same reference numerals, and redundant description thereof will be omitted. Note that, in this embodiment, in order to distinguish from other embodiments, a label of english capital letter S may be attached.

In the heat source-side module 30S of the second embodiment, the heat source-side heat exchanger module 50S further includes a third control portion 53 and a storage portion 54. The storage unit 54 stores control target values of control targets set for each component device in the heat source-side heat exchanger module 50S.

The third control unit 53 determines a control value of a predetermined control target so as to achieve the control target value, and controls the control target. Here, the third control unit 53 is different from the second control unit 52 in that it can control the control target independently of the first control unit 41 after being activated.

For example, the rotation speed of the fan 57 and the opening degree of the expansion mechanism 59 may be controlled to be set as predetermined control targets. In this case, the third control unit 53 controls the rotation speed of the fan 57 and the opening degree of the expansion mechanism 59 based on the detection information of the temperature sensor 58 and the control target value.

(6) Feature(s)

In the air conditioner 10S of the second embodiment, the heat source-side heat exchanger module 50S is provided with the third control unit 53 by adding or changing a part of the configuration of the air conditioner 10 of the first embodiment to or from the configuration of the air conditioner 10 of the first embodiment.

Therefore, in the case where the air conditioner 10S in the second embodiment includes the entire structure of the air conditioner 10 in the first embodiment, the above-described features (3-1) to (3-6) and the modifications (4-1) to (4-3) can be applied as they are.

In the air conditioning apparatus 10S according to the second embodiment, the heat source-side heat exchanger module 50S further includes the third control unit 53, and therefore, after the module 50S is activated, the third control unit 53 controls the constituent devices independently of the first control unit 41. For example, the third control portion 53 independently controls the rotation speed of the fan 57 and the opening degree of the expansion mechanism 59 based on the detection information of the temperature sensor 58 and the control target value. With this configuration, the entire air conditioner 10S can be efficiently distributed and controlled.

(7) Modification 2

In the air conditioner 10S of the present embodiment, as shown in fig. 15, the first control unit 41 mounted on one compressor module 40a may be used to control the plurality of refrigerant circuits introduced into the plurality of outdoor unit systems 5a, 5b, and 5 c. In this case, the second controller 42 is provided in the compressor modules 40b and 40c not having the first controller 41, and is controlled based on the control information from the first controller 41. Further, the heat source-side heat exchanger module 50S is provided with a second control portion 52 and a third control portion 53. Thus, the constituent devices of each heat source-side heat exchanger module 50S are controlled by the second control unit 52 based on the control information from the first control unit 41, or are controlled by the third control unit 53 independently of the control information from the first control unit 41.

In fig. 15, reference numerals 50Ss, 50St, and 50Su denote a first type heat exchanger module, a second type heat exchanger module, and a third type heat exchanger module, respectively, in the second embodiment.

Although fig. 15 describes "64 indoor units can be installed at maximum", this description is merely an example of the number of connected units of the use-side heat exchanger module 21 (indoor unit). This is merely an example, and the air conditioning apparatus 10 according to the present embodiment may include 64 or more use side heat exchanger modules 21.
