More Information About Sight Glass
What Is A Sight Glass?
For Optimum Performance A Cooling System Must Have A Solid Column of Light At The Expansion Valve. Sight Glasses Are Used To Determine The State of Charge. Sight Glasses And Moisture Liquid Indicators Ensure A Fast And Safe Inspection of The Conditions of The Refrigerant Fluid In The Circuit Concerning Regular Flow And Moisture. Liquid Indicators Also Ensure Inspection of The Regular Return of Oil To The Compressor Crankcase.

A Sight Glass Provides A Visual Indicator of Any "bubbles" In The Refrigerant Stream That Could Adversely Affect Performance. If The Charge And Working Condition Are Normal; The Refrigerant Fluid Appears Perfectly Liquid Underneath The "lens" of The Indicator. The Presence of Bubbles Indicates That The Refrigerant Fluid Is Partial Evaporating Along The Liquid Line. The Sight Glass Will Show Bubbles If The System Is Low On Refrigerant. The Sight Glass May Show A Few Bubbles When The System First Starts. Or; They May Appear Just As The System Stops. These Are Normal Equalizing Actions And Do Not Indicate A Shortage of Refrigerant. Bubbles May Also Show A Restriction In The Circuit Ahead of The Sight Glass. This May Be Due To A Partially Clogged Drier; Screen; Or Filter. The Sight Glass Has Long Extensions That Permit Soldering Or Brazing The Joints Without Injury To The "
