Smart Refrigerator Display

[Holland]

I'm recently working on a new project about smart fridge display and I made UI interface for it. But I I don't know much about refrigerators, maybe someone can recommend me a suitable and cheap compressor module?

What is a "compressor module" and what are you really trying to do?
Regulate temperature?

The refrigerator can be cooled, can't it? I guess it should be the compressor at work.
So in the process of simulating cooling I think a compressor should be needed.
I intend to control the components working through the serial screen and Raspberry Pi, and control the temperature of the refrigerator through the buttons or sliders on the touch screen.
