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.
high voltage side call primary
No, the liquid (discharge) line is the high pressure side. The suction line is the low pressure side.
It's installed on the high-voltage side.
An isolator is a non load-breaking switch, and is provides a visible means of isolating a component, such as a circuit breaker, transformer, etc., from the high-voltage lines, whenever it is necessary to perform maintenance of that component. Normally, isolators come in pairs, with one on each side of the component to be isolated. Isolators are only opened afterthe load current has been broken using a circuit breaker, and must be closed before the circuit breaker is reclosed.To work on, say, a h.v. circuit breaker, the breaker must be tripped, the isolators on either side must be opened and locked off, temporary earths attached to either side of the circuit breake- to-work card, detailing the maintenance work, must be issued to the crew by the supervising engineer.
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)
Low 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.
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 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.
One possibility is excessive refrigerant in the 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.
If you are asking why the low side is high and the high side is low that would indicate that you have a restriction in the a/c system...........
