Technical Field

[0001] This utility model relates to the field of mechanical refrigeration, and in particular to a compressor. Background Technology

[0002] A compressor is a driven fluid machine that raises low-pressure gas to high-pressure gas. Compressors are widely used in industries such as air conditioning, heat pumps, and ice storage.

[0003] Currently, compressors can be controlled using PLCs (Programmable Logic Controllers). This control method typically requires separate CPU, DI, DO, TI, AI, and AO modules, resulting in high hardware costs. It also necessitates an additional electrical cabinet to house the PLC hardware, occupying more space. The scalability of a PLC control system is limited by its hardware and software architecture. When adding new control functions or expanding the system size, it may be necessary to replace the PLC with a higher-performance one or add additional expansion modules, which can increase system complexity.

[0027] The present invention will be described more clearly and completely below by way of embodiments and in conjunction with the accompanying drawings, but the present invention is not limited to the scope of the embodiments.

[0028] like Figures 1-2 As shown, this embodiment includes a compressor 100, which specifically includes a junction box 12, a microcontroller module 13, and a cable 14. The junction box 12 is located on the body 11 of the compressor 100, and the bottom of the junction box 12 has an opening 121. The microcontroller module 13 is located inside the junction box 12 and is communicatively connected to the body 11 via the cable 14, which passes through the opening 121.

The functions of the microcontroller module 13 include compressor capacity regulation control, operation data acquisition, historical data collection, compressor cooling control, unit hot gas bypass control, compressor protection function, magnetic controller protection function, and frequency converter protection function. By placing the junction box 12 in the body 11 of the compressor 100 and placing the microcontroller module 13 inside the junction box 12, and setting the microcontroller module 13 to be able to control the body 11, it is possible to avoid setting up a separate electrical cabinet, save space, improve the integration of the compressor 100, and reduce the cost of the compressor 100.

Currently, there are many brands of microcontroller module 13 chips on the market, with low prices and diverse choices. Correspondingly, the microcontroller module 13 also has the characteristics of low price and diverse choices.

[0034] In this example, the microcontroller module 13 is small in size and lightweight, allowing it to be embedded in the compressor 100's housing 11 without the need for an additional electrical cabinet, thus saving space occupied by the control system. The microcontroller module 13 can also integrate multiple I / O ports, enabling it to easily add new control functions without requiring additional hardware, thus offering strong scalability.

[0035] As one implementation method, the port configuration of the microcontroller module 13 can be as follows: Figure 2 As shown in the figure, the microcontroller module 13 specifically includes a power input interface, a three-phase sequence detection interface, AC 220V and DC 24V relay outputs, digital inputs, PT100 temperature detection, PTC temperature switch, current transformer, RS485 communication interface, expansion board interface, analog input / output interface, electronic expansion valve drive terminal, real-time clock power interface, etc.

[0037] exist Figure 1 In this example, the microcontroller module 13 is integrated into the housing 11 of the compressor 100. A junction box 12 can be soldered onto the housing 11. The microcontroller module 13 and the wiring terminals 15 can be bolted into the junction box 12. The bottom of the junction box 12 has an opening 121 for connecting the microcontroller module 13 to external cables 14. After wiring is complete, the outer cover can be locked. This example compressor 100 integrates the entire control system into the housing 11, reducing the overall cost of the control system, saving space occupied by the control system, increasing I / O expandability, and facilitating upgrades to the compressor 100's functions.
