Should bubble be green if air conditioner is full?

If you are referring to the sight glass, the liquid beneath the glass should flow clear without bubbles when properly charged with refrigerant.


What do bubbles in the sight glass mean?

Bubbles normally means air intrusion into a system. If it is your air conditioner, then you most likely have a cooling coil leak. Other systems would be were you are drawing a vacuum. This is most likely at the suction of a pump or compressor. Good luck! Actually, the bubbles could be completely normal. On the high pressure side, bubbles simply mean not all the high-pressure refrigerant has condensed. Some of it remains as vapor. It could mean you are low on refrigerant, or the high side temp is too high (blocked condensor maybe). In an auto, it is not unusual to have a few bubbles in the sight glass unless you're driving or have a big fan forcing ais across the condensor. There are several reasons for bubbles in the sight glass. If one of the traditional refrigerants showed vapor in the sight glass it often meant there wasn't enough liquid refrigerant being fed to the valve, and more refrigerant was added to the system. Blends could show flashing for the same reason, however, they can also flash when there is plenty of liquid in the receiver. Ironically, this liquid in the receiver could be causing the problem, particularly when the equipment is in a hot environment. Blends will come out of the condenser slightly subcooled - at a temperature below the saturated temperature of the blend at the existing high side pressure. Yet when the blend sits in the receiver, it can "locally fractionate," or change composition slightly by shifting one of the components into the vapor space of the receiver. This will effectively produce a saturated liquid in the receiver, at the same pressure you had before, which flashes when it hits the expanded volume of the sight glass. In most cases these bubbles will collapse when the blend gets back into the tubing which feeds the valve, and the system will operate just fine. Check other system parameters such as pressures, superheat and amperage to confirm whether you have the right charge. Don't rely solely on the sight glass.


What is sight glass?

Units that allow observation of fluids inside a vessel, tank or pipe is called sight glass. Using sight glass, plant managers can observe and note pressure changes, fluid reactions and so on inside a vessel, tank or pipe. Sight glass is also called viewing glass. Observing fluids and its changes play critical role in many processes. Sight glasses are usually corrosion, abrasion and pressure resistant. There are different kinds of sight glasses available in the market. Sight Glass is usually designed in metal frames made of glass disks and meets the requirements of sanitary fittings. Sight glasses are used in fluid handling systems, boiler systems, industrial burners, pulp and paper processors, oil and gas refineries, automobiles, combustion equipment etc. Noble Glassworks is a leading sight glass manufacturer in India whom you can get in touch for all kinds of sight glass supply.

How can identify the presence of flash gas in the liquid line?

You can identify the presence of flash gas in the liquid line of a refrigerator by detecting the presence of bubbles on the sight glass. There will also be some vapour present. When this occurs, the refrigerator will not be able to work efficiently.
