Condensing Unit... From VAMP Maintenance
The refrigerant is pumped round the system, one way or the other. The warm side is the high-pressure side on one side of the nozzle.
No, the liquid (discharge) line is the high pressure side. The suction line is the low pressure side.
high voltage side call primary
In a vacuum system, the division points between high-pressure supply piping and lower-pressure return piping typically occur at the inlet and outlet of the vacuum pump. The inlet side, where the high-pressure gas enters, is connected to the supply piping, while the outlet side, where the gas is expelled after being evacuated, connects to the return piping. Proper sealing and valve configurations are essential at these division points to maintain the required pressure differentials and system efficiency.
It's installed on the high-voltage side.
Excessive refrigerant charge, or (less likely) a blockage or kink in the high side piping.
The 'R' group (side-chain).
The high-side service valve is closed during charging to prevent the flow of refrigerant to the low-pressure side of the refrigeration system. This valve is typically located on the discharge line of the compressor and is used to isolate the high-pressure side of the system during service or maintenance.
If a vector, of magnitude v, makes an angle of Φ with the adjacent side then the adjacent component = v*cos(Φ), and opposite component = v*sin(Φ)
A low pressure reading on the high side of an HVAC or refrigeration system typically indicates a potential issue, such as insufficient refrigerant, a blockage in the system, or a malfunctioning component like the compressor. It can also suggest that the system is not effectively transferring heat, which may lead to reduced cooling efficiency. Diagnosing the underlying cause is essential to prevent further damage and ensure optimal system performance.
Low side.
Most weather systems in the temperate latitudes move from west to east. This makes the west side of a system the trailing side. In the northern hemisphere, high-pressure systems rotate clockwise, resulting in southerly winds on the west (trailing) side.
The condenser is on the high pressure (discharge) side of the system.
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.
The accumulator is a component on the low pressure (vacuum) side of an air conditioning system which uses a fixed orifice tube - they won't be found on a Thermal Expansion Valve system.
Refrigerant should be added through the low side of the system. This is typically done while the system is running, as adding refrigerant through the high side can be dangerous due to high pressures. It is important to follow manufacturer guidelines and use proper equipment when charging a refrigeration system.
One possibility is excessive refrigerant in the system.
