Air-conditioner
The air-conditioner refers to the equipment that uses artificial means to adjust and control the temperature, humidity, flow rate and other parameters of the ambient air in a building or structure. The structure of the air conditioner includes: compressor, condenser, evaporator, four-way valve, one-way valve capillary assembly, etc. It is an indispensable part in modern life.
Based on MindMotion’s MM32SPIN0280 and MM32SPIN06 microcontrollers, the outdoor air-conditioner takes MM32SPIN37 and MM32SPIN06 as the main control.
