Is it bad to turn a mini fridge off and on?

So I rent a very small room in a very old house. There's no central AC and there's very insufficient airflow in my room. I wanted to buy an AC (the stand up one with the tube that goes through the window. But I also have a small mini fridge and l'm worried about the outlet short circuiting

Would it be alright to unplug my mini fridge once a day for a few hours while I plug my AC in, and then unplug my AC once it cools my room and then plug my fridge back in?

Or would this cause strain on the mini fridge? Should I wait longer before plugging it back in?
