Embodiment approach 1

[0025] The structure of the air conditioner of this Embodiment 1 is demonstrated. figure 1 It is a block diagram showing a configuration example of the air conditioner in Embodiment 1 of the present invention. Such as figure 1 As shown, the air conditioner 500 has an outdoor unit 200 and an indoor unit 300 . The indoor unit 300 has a control unit 302 , a communication unit 304 , a fan 306 , a load side heat exchanger 308 , and an expansion valve 310 . The indoor unit 300 is provided with an indoor temperature sensor 312 for detecting an indoor temperature. The fan 306 supplies indoor air to the load-side heat exchanger 308 .

[0026] The outdoor unit 200 has a control unit 202 , a communication unit 204 , a fan 206 , a heat source side heat exchanger 208 , a four-way valve 210 , and a compressor 212 . In the compressor 212 , a discharge port pressure sensor 216 is provided on the refrigerant discharge port side, and a suction port pressure sensor 218 is provided on the ref...

Embodiment approach 2

[0071] This second embodiment is a case where the external storage device 100 described in the first embodiment is a detachable memory that is detachably attached to the air conditioner 500 . The removable memory is, for example, a USB (Universal Serial Bus) memory or an SD (Secure Digital) memory card. The following describes the case where the detachable storage is a USB storage.

[0072] The configuration of the air conditioner according to Embodiment 2 will be described. In Embodiment 2, the same reference numerals are assigned to the same configurations as in Embodiment 1, and detailed description thereof will be omitted. Figure 9A It is a figure which shows a structural example of the air-conditioning apparatus in Embodiment 2 of this invention.

[0073] exist Figure 9A The indoor units 300A to 300C shown in the figure have the same configuration as the indoor unit 300 described in the first embodiment. exist Figure 9A The USB memory 100A shown in the figure corr...

Deformed example 1

[0083] Figure 10 It is a figure which shows the modification 1 of the air-conditioning apparatus in Embodiment 2 of this invention. is expressed in Figure 10 Front appearance view of a configuration example of the remote controller shown in . In modification 1, such as Figure 10 As shown, remote controllers 400A to 400C are connected to the indoor units 300A to 300C. Such as Figure 11 As shown, a USB port 411 is provided on the remote controller 400A. The position of the USB port 411 is, for example, the side surface of the remote controller 400A. In addition, the remote controller 400A has a display unit 412 for displaying.

[0084] When USB memory 100A is connected to USB port 411 provided in remote controller 400A, USB memory 100A can communicate with indoor unit 300A and outdoor unit 200 via remote controller 400A. The control unit 202 may be configured to display on the display unit 412 information that the USB memory 100A is attached, when the control unit 202...

Abstract

This air conditioner has: a plurality of devices that include at least a compressor; and a control unit that stores device information showing the type of each device. The control unit has: a programconfiguration means for retrieving the control parameters and control programs of the device corresponding to the device information from an external storage device that stores control parameters andcontrol programs on a device-by-device basis; and a refrigeration cycle control means for controlling the device according to the control programs retrieved by the program configuration means.

Description

technical field [0001] The present invention relates to an air conditioner for performing refrigeration cycle control. Background technique [0002] As an example of a conventional air conditioner, an air conditioner that controls a refrigeration cycle according to a program is disclosed (for example, refer to Patent Document 1). The air conditioner of Patent Document 1 controls the rotational speeds of the compressor and the fan according to the program stored in the storage unit. [0003] Patent Document 1: Japanese Patent Laid-Open No. 2016-151385 [0004] In the air conditioner disclosed in Patent Document 1, the control of the refrigeration cycle is operated according to a single program including common functions and unique functions of the equipment. Therefore, every time the model of the air conditioner is expanded, it is necessary to create a program corresponding to the new model, and model expansion cannot be easily performed. Contents of the invention [000...
