How does a central air conditioning system work?
As the liquid refrigerant inside the evaporator coil converts to gas, heat from the indoor air is absorbed into the refrigerant, thus cooling the air as it passes over the coil. The indoor unit’s blower fan then pumps the chilled air back through the home’s ductwork out into the various living areas.
What is central air conditioning system?
Central air conditioning (or central A/C) is a system in which air is cooled at a central location and distributed to and from rooms by one or more fans and ductwork. The work of the air conditioner compressor is what makes the whole process of air conditioning possible.
What is AC system PDF?

What part of the air conditioner is inside?
Essentially, an AC is divided into two main parts: one half inside of your home containing an evaporator coil and a filter, and an outer half with a condensing coil, fan and compressor.
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 Freon®) is a special fluid that is vital to cooling and freezing technology.
- Compressor.

What is the most expensive part of an air conditioner?
air compressor
What are the two copper line on an air conditioner?
Refrigerant lines are two copper lines that connect the outdoor air conditioner or heat pump to the indoor evaporator coil. The larger line typically carries a cool gas and is insulated. This is commonly referred to as the suction line, but it is also called the return line or vapor line.
What are the three major refrigerant lines?
The suction line connects the evaporator to the compressor, the discharge line connects the compressor to the condenser, and the liquid line connects the condenser to the expansion device.
How long do AC lines last?
eight years
Why copper pipes are used in air conditioners?
Copper as a metal has highly anti-corrosive properties compared to aluminium. During the cooling process, pipes comes in contact with air which causes oxidation within these pipes. Copper can better handle oxidation and corrosion for longer periods ultimately gives air conditioners a longer lifespan.
Which coil is better in AC Aluminium or copper?
Copper has a heat transfer coefficient higher than aluminium. That means, copper is a better heat exchanger than aluminium. 2) Cost and Pliability (The quality of being easily bent): Copper is costlier than aluminium, which increases the cost of making an air conditioner and thereby the price of air conditioner.
Which copper pipe is best for AC?
Copper Pipe Sizing
- Type K Copper Pipe: Type K copper pipe has the thickest wall of all the common types.
- Type L Copper Pipe: Type L copper pipe is used for interior plumbing, fire protection, and some HVAC applications.
- Type M Copper Pipe: Copper pipe type M wall is thinner than both type K and L copper.
What is the cost of AC copper pipe?
| Item Description | Price (Rs.) | Unit |
|---|---|---|
| Copper Pipe – diameter 1/4 Inch* | 250 | 1 meter |
| Copper Pipe – diameter 3/8 Inch* | 280 | 1 meter |
| Copper Pipe – diameter 1/2 Inch* | 360 | 1 meter |
| Copper Pipe – diameter 5/8 Inch* | 430 | 1 meter |
Is AC outdoor unit waterproof?
The outside portion is the condenser/compressor, and the indoor portion is the air handler that includes the evaporator coil. The outdoor portion of an A/C system is built to withstand the rain, and even severe rainfall will not damage it. The answer is: Yes, you can use these systems, even during heavy rain.
What are the charges for AC gas filling?

Which wire is best for AC?
Even though 4mm wires are better, your 1.5 ton ac should run on 2.5mm wires. When choosing wire gauge, the length of the wire is very important. The next bigger size wire is used for installations over 30 metres.
Is 2.5 mm wire enough for 1.5 ton AC?
Your 1.5 ton ac draws around 8~9A and should run on 2.5 mm wires even though 4 mm is better. Finally, length of the wire also plays a crucial role when choosing wire gauge. For installations longer than 30 metres use the next bigger size wire. Lengths are measured from meter/main juntion box.
How many amps does a 1.5 ton AC consume?
Approximately 15 amps. 1 Ton yields approximately 10 amps of draw. In example a 40 amp 240 volt or 208 volt will draw approximately 9600 Watts at 240 and approximately 8320 Watts at 208.
Can I connect a 1.5 ton split AC with a 2.5 sq mm wire?
Yes a 2.5sqmm wire can be used. Earth wire also must be of 2.5sqmm don’t skip earthing. On split AC the wire that went to exhaust or outdoor unit can be 2.5 sqmm.
How many amps can a 2.5 mm cable take?
23-25 amps
What is the current carrying capacity of 2.5 mm cable?
Single-Core 90°C Thermosetting Insulated Cables, Non-Armoured, with or without Sheath
| Current-carrying Capacity (amperes): | ||
|---|---|---|
| Conductor cross-sectional area | Reference Method A (enclosed in conduit in thermally insulating wall etc.) | Reference Method C (clipped direct) Spaced by one cable diameter |
| 1.5 | 19 | 25 |
| 2.5 | 26 | 34 |

What is the difference between 1.5 mm and 2.5 mm cable?
You will find twin core and earth cabling used all over your home in a variety of sizes. 2.5mm is commonly used for behind sockets, while 1-1.5mm is most often used for lights (depending on how many lights you have in a circuit).
Can I use 1.5 mm cable for sockets?
Use 2.5mm twin and earth cable for all single and double sockets as 1.5mm cable can only handle 14 to 20 amps at 230 volts. It is common for 1mm and 1.5mm to be used for radial lighting circuits, and 2.5mm cable is normally used for ring main wall sockets.
What is 1.5 mm2 cable used for?
1.5 mm is most commonly used for lighting circuitry and switches. 2.5 mm is most commonly used for ring mains, plug and socket wiring. 4 mm is most commonly used for high power ring mains, plug and socket wiring. 6, 10 and 16 mm are most commonly used for high powered small appliances such as cookers.
