What is the price of the copper pipe of the ceiling air conditioner

In the past, cast iron pipes were generally used, and it didn't matter if there was a small crack, as long as the water was not blocked, it would not overflow, but now PPR pipes or PVC pipes are generally used.

The ceiling height of the central air-conditioning room is generally not less than one meter ninety-five, so if the room is too low, the air conditioner should be hoisted on the top.

You're talking about the end of the central air conditioner, right? Like a fan coil unit. Anyway, the main machine can't hang it. Depending on the height of the house, it is about 50-80cm from the top

The thickness of the central air conditioning indoor unit is 200mm, plus the thickness of the pipe and the drainage space are about 50mm, so it is enough to reserve 250mm for the central air conditioning ceiling.

The bed should be placed in the north-south direction, because when the head is facing south to sleep, the direction of blood circulation is the same as the direction of the earth's magnetic field lines, people are easy to fall asleep slowly, and the quality of sleep digging is also high, and the east-west direction of the bed, the direction of human blood circulation is exactly in the cutting direction of the earth's magnetic field lines, which will make sleep unstable and not good for health.
