The AC unit was an early form of GE's Thinline line. It was not actually a large enough AC unit for a kitchen because these units ran about 8 or 9,000BTUs, but it was not a deep unit. These were often in motel rooms in the 50s and early 60s. I think they were sized for nightime use because the room would not be really cool if you were in it during the day. I will give you that there might be certain liberties taken with the sight lines, but I have a regular refrigerator set into cabinets and the cabinet above the box is very deep, like you have to be standing on a step stool and have long arms to reach the back of it deep, so I question the positioning of the air conditioner.
In the turquoise kitchen, that is an upright freezer next to the fridge. See the lock about midway up the door on the left side? The door handle is high to keep crumb crunchers out.
