[0068] (1) Overall structure

[0069] figure 1 It is a schematic diagram for explaining the outline|summary of the air-conditioning apparatus 10 in 1st Embodiment. figure 2 It is a schematic diagram which shows an example of the refrigerant circuit 15 of the air-conditioning apparatus 10 in 1st Embodiment.

[0070] In addition, in the following description, in the case where a plurality of devices having the same function are commonly described, the same reference numerals are used for description. In addition, when describing one device differently from a plurality of devices having the same function, the description is given with a suffix of lowercase letters.

[0071] In the air conditioner 10 , the utilization-side unit 20 and the heat-source-side unit 30 are combined to form a refrigerant circuit 15 .

[0072] The usage-side assembly 20 has at least a usage-side heat exchanger module 21 . The usage-side heat exchanger module 21 has at least a heat exchanger and a fan, ...

[0123] (5) Detailed structure of heat source side components

[0124] Figure 14 It is a schematic diagram which shows the control system of the heat source side assembly 30S in 2nd Embodiment.

[0125] Hereinafter, substantially the same reference numerals are attached to the same parts as those already described, and redundant descriptions will be omitted. In addition, in order to distinguish it from other embodiments, in this embodiment, a notation of an English capital letter S may be added.

[0126] In the heat source side assembly 30S of the second embodiment, the heat source side heat exchanger module 50S further includes a third control unit 53 and a storage unit 54 . The memory|storage part 54 stores the control target value of the control object set individually for each component device in the heat source side heat exchanger module 50S.

[0127] The third control unit 53 determines the control value of the control target for a predetermined control target so that...

[0134] In the air conditioner 10S of the present embodiment, if Figure 15 As shown, the plurality of refrigerant circuits introduced into the plurality of outdoor unit systems 5a, 5b, and 5c may be controlled by the first control unit 41 mounted on one compressor module 40a. In this case, the second control unit 42 is provided in the compressor modules 40 b and 40 c that do not have the first control unit 41 , and is controlled based on control information from the first control unit 41 . Moreover, the 2nd control part 52 and the 3rd control part 53 are provided in the heat source side heat exchanger module 50S. 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 by using the third control unit 53 and the control information of the first control unit 41 independently controlled.

Abstract

The present invention provides an air conditioner having an optimum structure corresponding to design specifications of a building. In the air conditioner (10), at least one compressor module (40a) is separated from at least one heat source side heat exchanger module (50), is connected via piping, and is configured as a group with the utilization side heat exchanger module (21) Refrigerant circuit. In addition, the heat source side heat exchanger module (50) includes a first type heat exchanger module (50a) that blows air upward, a second type heat exchanger module (50b) that blows air sideways, and an inclined Any one of the third type of heat exchanger modules (50c) that blows air in the direction, or any combination thereof. With such a structure, it is possible to introduce an air conditioner (10) having an optimal structure according to the design specifications of the building.

Description

technical field [0001] The present invention relates to air conditioners. Background technique [0002] An air conditioner in which an outdoor unit is divided into a compressor unit and a heat exchanger unit is being studied (for example, Patent Document 1 (JP-A-10-170034)). [0003] In recent years, due to the diversification of the appearance of the building and the surrounding environment, etc., the requirements for the installation places of the equipment introduced into the building are becoming more and more diverse. In addition, after the equipment is installed, the load on the indoor side may increase, or the surrounding environment of the installation place of the outdoor unit may change. In this case, the capability of the facility equipment becomes insufficient, and it is necessary to add new facility equipment. Contents of the invention [0004] The present invention provides an air conditioner having an optimum structure corresponding to design specification...
