Ch 7. 1 use of copper tube in refrigeration /HVAC
- 1. Lesson 1
- 3. Copper TubingThe tubing is considered the vital part of the refrigeration system.
- 4. Most common materials in the refrigeration piping circuit. Copper Tubing
- 5. Copper TubingUsed to connect the major parts of the refrigeration system.
- 6. Copper TubingMost copper tubing is available from 1/8 inch to ¾ inch of a diameter.
- 7. Copper TubingThe end are capped or plugged to keep the inside of the tubing clean and dry.
- 8. Copper TubingAvailable in 3 Types: Type k Type l Type m
- 9. Type k: Used for heavy duty purpose because of its thick wall.
- 10. Type l: Used for six interior plumbing and heating. It is the common types used in HVAC system.
- 11. Type m: Used for light duty work.
- 13. Used in domestic and some commercial refrigeration and air conditioning work.
- 14. Being bendable, this tubing must be supported by suitable brackets or clamp in installation.
- 15. It is sold in rolls of 1, 35, and 50 ft long.
- 17. Used in commercial refrigeration and air conditioning applications.
- 18. Being hard and stiff, it needs few clamps to support it in installation.
- 19. It should not be bent so use straight lengths and fitting to form the necessary tube connection.
- 20. Its joints should be silver brazed to eliminate leaks.
- 22. A thin wall tubing used in refrigeration and air conditioning work.
- 23. Its size is practically the same as that of copper tubing.
- 24. Connections may be made on steel tubing by using either flare joints or silver brazed joints.
- 26. A strong type of tubing that is very resistant to corrosion.
- 27. It is easily connected to fitting by either flaring or brazing because of this qualities.
- 28. Often required in food processing, ice, oven, manufacture, milk handling system, and similar works.
- 29. PlasticPlastic
- 30. One of the most common substances used in the manufacture of plastic tubing.
- 31. The usual safe temperature is from 100 degrees centigrade (oC) to +175 (oC) you should never use this tubing where fluid temperature goes beyond this limit.
- 32. Not used in refrigerating mechanism but in cold water lines in water cooled condensers.
- 34. Commonly used in many refrigeration system and in commercial air conditioning application.
- 35. It serves to prevent vibration in the mechanism.
- 36. A motor vehicle requires the use of flexible tubing since the vehicle is always moving.
- 38. Usually used for evaporating units in air conditioning for home and auto-mobile.
- 39. It is used for evaporator (freezer) of the domestic refrigerators.
- 41. fittings A device used to connect tubes of different widths and lengths.
- 43. Used in flared type connection to attach fittings in copper tubing.
- 44. There are many different fittings which are hexagonal in shape for wrench attachment.
- 45. These threaded fittings must be carefully handled to prevent damage.
- 46. All fittings Used are based on the tubing size.

- 64. Used in most tubing and fitting connections that are either by soldering or silver brazing.
- 65. Soldered joints are used for water pipes and drains.
- 66. Silver brazed joints are used for refrigerant pipes and fittings.
