Technical details of Air Condition (AC)

Let dive in detail of each technical feature/point of the Air conditioner to see what is best and the value for the money option available for us. So instead of buying the expensive, wrong AC, we will help you not only to choose the  BEST AIR CONDITIONER  and most affordable & efficient Air conditioner but also a powerful one loaded with required latest technology for your home. And I bet you that you will be also surprised to know that it’s not always correct to buy the latest & expensive technology Air conditioner (AC) as it may not be most suitable one for your home 

Because it depends on your:-

  • Usage hours of AC, your location of the house.
  • The direction of the window.
  •  Number of glass on your window door.
  • The shape and size of your room or living room.
  • Exposure of wall and roof to sunlight.
  • Number of equipment and furniture in the room.

Inverter AC vs Non Inverter AC:

    • Inverter AC can run at various speeds and variable tonnage or watt of load as per requirement of temperature of room.
    • On the other hand, non-inverter AC units run at a constant tonnage and speed and its simply operate on and off while regulating the temperature.
    • Inverter AC units are more efficient than the non-inverter ACs in long RUN and if you usage is high or you are a continuous user.

Copper Coil vs Aluminium Coil:

  • Copper is expensive & better than aluminium good and  in long run , repair cost and durability, corrosion,  strength heat Transfer.
  • A leak in the copper coil can be repaired easily and save you from costing of replacing the complete coil. However, it is far more difficult to wield or solder aluminium.

There are different categories or types of Air condition ranges from window AC, Split AC, Ductless AC, Central Air condition, Tower AC.

Window AC: fits in the window can be easier to use for rented houses. And have high cooling but electricity usage is also high & high compressor noise.

Split AC: The ac which has a separate outdoor and indoor unit. Mainly the compressor is an outdoor rest blower is inside the unit. It's bit costly in price but electricity cost of usage is lower than the window. The service cost is high. Low noise.

Cassette  AC:  Installed in celling and mainly used in office and a big house or villa. Is very expensive and

Portable Ac:-   A small AC about 110 capacity and cooling and air blower everything is is inside, But it also required space to fit an exhaust pipe from which it can blow the hot air out.

Tower AC:-  Kind of  Big portable AC   but mobility is restricted to a few meters. It can be used at the office gate and can be used at the marriage function and party. Where the doors are open and closed many times

  • Chill Mode /Himalayan Mode: AC will more with full power
  • Dry Mode: Remove the access of humidity from the air.
  • Sleep Mode: Can be set the timer for sleep or switched off.
  • Hot & Cold AC: Air condition that works in all weather by providing you instant cooling in summer and keep you warm in winter.
  • 3 M micro Electrostatics Air Conditioner filter which removes air pollution as well.
  • Blue Fin? Blue Fin is an anti-corrosive coating that prevents rusting to a certain degree and prolongs the life of an air conditioner. LG offers Ocean Black protection that is similar.
  • Mosquito Away technology? LG air conditioners can emit ultrasound waves to keep mosquitoes away. This type of sound cannot be heard by humans but helps to drive away mosquitoes.
  • Dual inverter Air condition.
  • Hot and Cold AC

Size or capacity of Air Condition (AC)– TON

 The following table will help you choose the right size of the air conditioner according to the room size. So that you can choose your required TON of AC. 

Ton is a number that tells how much heat the air conditioner can remove or soak from the house in an hour. TON is measured in BTU.1 TON= 12000 BTU per hour means it can extract 12000 BTU of heat from room in one hour.

Ton is a number that tells how much heat the air conditioner can remove or soak from the house in an hour. TON is measured in BTU.1 TON= 12000 BTU per hour means it can extract 12000 BTU of heat from room in one hour.

As we know that all the household electrical equipment have star rating which depends on EER and in India its ISEER.In a room, you can measure the air conditioner’s efficiency by the Energy Efficiency Ratio (EER). EER is the ratio of BTU PER HOUR to the input power watt USED TO controlled  environment using 35 degree Celsius

 EER = cooling Capacity /power input

ISEER (Indian Seasonal Energy Efficiency Ratio): ISEER (Indian Seasonal Energy Efficient Ratio) rating standard is mandatory from 2018. Both SEER and ISEER are the same.

ISSER rating is the total cooling load (amount of heat removed) to the total amount of energy consumed by the air conditioner. This means, ISEER = Cooling seasonal total load (CSTL) / Cooling seasonal energy consumption (CSEC). The ratio calculated is then used to select the correct star ratings  .i.e.    ISEER = CSEC/CSTL

*CSEC (Cooling Seasonal Energy Consumption): CSEC means the total energy that is consumed by the AC when it remains in the active mode.*CSTL (Cooling Seasonal Total Load): CSTL means the total amount of removed heat by the AC unit while it is active.

Currently required ISEER rating standard are as follow.

So Star rating depend upon ISEER it generally range from 2 to 5

1BTU = 0.293 w & 1 watt = 3.412 BTU/Hr

1 TON AC = 12000BTU, 

And One kilowatt-hour (kWh) of electricity that is one unit of electricity contains 3,412 Btu.

One ton is equal to the amount of heat required that to melt one ton of ice in a 24-hour period and ie is 288,000 BTU

  • 1 TON AC =  3.5KW

    And with 5 star rating  = AC will be 3.5KW/3.5(5 star ISEER value)=1KW i.e 1000wattt.

    So 1 ton ac with 5 star Ratting is having load of 1000 watt. Means running the  5 stat I TON AC for 1 hr will cost you 1 unit of electricity bill.

  • Last but not least before buying any brand AC I would suggest to take the customer care number from their respective website and call them to check that they do provide service in your area, and what is TAT to   resolve the issue of customer.
