Overcharge would be my guess.
Low side pressure is normally 28-38 high side pressure is typically 100 + outside temperature
High side and low side refer to the pressure in the ac system. Ie The high side is the high pressure line and low side is the low pressure line.
You need to specify what kind of system. Automotive AC systems and home AC systems use different refrigerants. That, along with the temperature/pressure relationship and ambient air temperature, all factor into what your high pressure (and, consequentially, low pressure) side should read on your manifold pressure gauge.
Air blows from low pressure side from upper presser side i.e,high temperature area to low temperature area.
No, the liquid (discharge) line is the high pressure side. The suction line is the low pressure side.
Red is the high side.. The low side is blue..
The compressor changes the low pressure gas into a high pressure gas which then has the heat of compression removed in the condensor to turn it into a high pressure liquid.
its can be a restriction in liquide line
The difference would be due to the different refrigerants used by each which is not given. Also the refrigerator will have a more constant condenser pressure because it is within an environment where the ambient temperature varies little.END
On a manifold gauge set, there are two gauges. The gauge encased in red measures pressure on the high pressure (discharge) side. That's the "high side gauge". The other will be incased in blue, and measures vacuum pressure on the low side.
The high pressure side.
These are terms used by refrigeration and air conditioning techs. The suction is refrigerant returning to the compressor from the evaporator, or the low side. The high side is the discharge or head pressure, where high temperature high pressure gas leaves the compressor to flow into the condenser. These systems should only be worked on by licensed and experienced techs.
