Room Liquid Line
Liquid line contains several important points, checking:
- Size of the liquid line.
- I-and stop valves.
- Sight glass.
- Moisture indicator.
- Strainer.
- Drier or a dehumidifier.
- Vibration absorber.
- - Compounds.
- Solenoid valves.
- Joints.
- Pinched or buckled pipes or tubes.
When the system diagnostics trouble, first, determine whether each piece is required performance. Liquid line should be as large as the condensing liquid receiver valve connections. Make sure that the valve gearbox, were not used. Many large units use different sizes of the liquid line. At least one end of the liquid line valve should be opened when servicing the device. Otherwise, higher temperatures can create a high hydrostatic pressure, which can break a line. Be especially careful if solenoid valve, littering the screen, or clogged desiccant in line. Check the condition of the die full length of the string. Lines should be protected from abrasion and ill-treatment and moving objects.
The line should be well supported along its full length.
Take care when taking liquid refrigerant in the liquid line through the liquid receiver service valve. Always open the valve slowly. A sudden rush of fluid can damage the screen or bag with desiccant in the dryer so firmly that he will score. Test all connections are tight. Check the temperature of the liquid line. They should be close to room temperature along its full length. Lower than normal temperature at the output indicates partially obstructed screen or dryer. Sweating and even frostmg may be seen. There will also be the excessive pressure drops. This can lead to bubbles in the sight glass.
