What are the four main components in an air conditioning system?
In reality, the average air conditioner can be broken down into four main components: the evaporator coil, compressor, condenser coil, and expansion valve. Each component plays a unique role in helping your central air conditioner provide cooling comfort for your home.
What is the basic principle of air conditioner?
The basic AC principle is a vapor compression cycle to minimize the air temperature with the help of a condenser, compressor, expansion valve, and evaporator. The complete cooling process is a heat transfer taking place among the room air and refrigerant gas.
What are the five basic parts of air conditioning system?
An air conditioner has 5 main parts:
Refrigerant. Refrigerant (also known as coolant or by its brand name FreonĀ®) is a special fluid that is vital to cooling and freezing technology.
Compressor.
Condenser Coil.
Expansion Valve.
Evaporator Coil.
What are the 4 most important factors in an electric circuit?
Every electric circuit, regardless of where it is or how large or small it is, has four basic parts: an energy source (AC or DC), a conductor (wire), an electrical load (device), and at least one controller (switch).
What is a live electrical circuit?
A live circuit is a circuit which has power actively passing through it. This means that the power source which is the powering the circuit is turned on, and the circuit has current passing through it.
What safety precautions should you take when working with electricity?
Safety Precautions When Working With Electricity
1- Make Sure Your Body Is Dry. Often we have seen people touching electrical cables and charges with wet hands.
2- Never Use Broken Equipment.

What is NO and NC In Contactor?
NO (Normally Open) is When a Magnetic Contactor has not been given an Electric voltage (Normal state), then this Pole is not connected (Open), then when the Coil on the magnetic contactor is given a voltage then this Pole will be connected (closed). NC (Normally Close)
Why would you use a relay instead of a contactor?
Relays are switching devices used in any control circuit for checking a condition or multiplying the number of contacts available. Contactors are switching devices used to control power flow to any load. Mainly used in control and automation circuits, protection circuits and for switching small electronic circuits.
