Vacuum drying is : The use of a vacuum pump to vaporize(gasify) the moisture (liquid) inside the pipe and expel it leaving the pipes completely dry inside. At 1 atm(760mmHg) the boiling point (evaporating temperature) of water is 100℃(212℉) but if a vacu- um is created inside the pipes using a vacuum pump then the boiling point is rapidly reduced as the degree of the vacuum is increased.

  • Page 69 SINGLE ZONE 2. Guideline for each installation process 2) Vacuum pump maintenance Because of their nature, most vacuum pumps contain large amounts of oil which lubricates bearings, etc., and functions to enhance airtightness of pistons. When using a vacuum pump to discharge air from refrigerant piping, moisture in the air tends to get mixed in with the oil.
