Question

Accepted Answer

The answer to the questions related to AC Technician interview.

There are four refrigeration cycles: vapor compression, absorption, steam jet, and air cycle.
There are various types of compressors used in AC systems, such as reciprocating, rotary, scroll, and centrifugal compressors.
Compressors can have different types of connections, including sweat connections, flare connections, and threaded connections.
TXV (Thermostatic Expansion Valve) and EXV (Electronic Expansion Valve) are types of expansion valves used in refrigeration systems to control the flow of refrigerant.
A solenoid valve is an electromechanical device that controls the flow of refrigerant in an AC system. It opens and closes based on electrical signals.
RLA (Rated Load Amps) and LRA (Locked Rotor Amps) are electrical ratings used to specify the current draw of an AC compressor under normal and locked rotor conditions, respectively.
Copper pipes are typically brazed using an alloy called silver brazing alloy, which contains silver and other metals.
To fill oil in a compressor, the technician needs to follow the manufacturer's guidelines and use the recommended type and amount of oil for the specific compressor model.
