Does high pressure rise and low pressure sink

High pressure is associated with sinking air, and low pressure is associated with rising air the opposite occurs with high pressure. Air is moving away from the high pressure center at the surface so as a result, air from above must sink to take its place.

They use refrigerant, which freon is a type of. For the cooling mechanism of a refrigeration machine, a compressor pushes the liquid coolant out and into the expansion evaporator. The evaporator uses the cool temperature from the coolant and uses the forced air from a fan (example for AC or fridge) and into an expansion valve that regulates its flow to the next step. It then goes to a condenser where it goes back into a fluid from gas form and back to the compressor. I left a few steps out (it's been a while).
