Different Types of AC
Generally, there are six different types of ac that are available in the market and these divisions are based on the shape and size of the room where it is placed.
What are the points you should keep in mind about installing an Air-Conditioner?
The most important factor for normal people is budget.
- The cheapest option available for us is the window and portable air conditioner.
- If your requirement is to cool more than one room then a ductless air conditioner is more cost-effective for you.
- If you want an air conditioner that lasts long and gives you more effective cooling then you should switch to central air conditioning but it is more expensive than the above two.
- If you want an air conditioner that you install once and long last till you survive, then you have to go for a geothermal air conditioner. But it is the most expensive air conditioner.
2. Room Size
The first thing you want to know before you install an air conditioner is your size. How much area do you want to cool?The power of the air conditioner is measured in tons.
1 ton = 12000 BTU(British Thermal Unit) OR 3517 watts.
One ton means it is the amount of heat required to melt one ton of ice in 24 hrs.
Generally, 1.5 – 5 tons is required to cool the house while installing a centralized air conditioner. Room size of 1600 square feet, requires 3 tons of air conditioning units. But if your requirement is more than 5 tons, then it lights commercial HVAC units.
Room Size recommended:
- Requires 1.2 tons of air conditioner, if your room is less than 120 sq. feet.
- Requires 1.4 – 1.5 tons of air conditioner, if your room is between 121 -179 sq. feet.
- Requires 2 tons or above of air conditioner, if your room is greater than or equal to 180sq feet.
Other factors that affect the capacity of the air conditioner are:-
If you are living on the top floor then you require the highest capacity of an air conditioner. As you move towards the upper floor, your requirement for the capacity of air conditioner increases.
Your surrounding temperature plays an important role in deciding the capacity of the air conditioner required.
- Multiple windows are also an important factor in deciding the capacity of the air conditioner required.
- Room orientation.
3. Power Rating
The Bureau of Energy Efficiency (BEE) has set the standard of rating the electrical appliances as by star. In the case of the air conditioner, this star refers to the Indian Seasonal Energy Efficiency Ratio. This tells you how much energy is consumed by the air conditioner to cool a home. More SEER rating means more efficiency or more star means better. It is recommended by experts that people who live in hot and humid areas should at least use 15 SEER rating and if you are using less than 10 SEER rating air conditioners then switch to 15, it will reduce your electrical bill.
It is necessary to check the warranties given by different companies. Some companies give more warranties and some less. You should also check what warranties they cover like Cover labor-related expenses for the very first year or lifetime warranty with labor cost.
5. Energy-saving features
- Variation in speed motor: It increases the efficiency of airflow, as it adjusts its speed according to the requirement.
- Two-stage cooling: Compressor of the air conditioner comes in two different cooling – high & low. It adjusts themselves according to their requirement. If it runs on low cooling, it consumes less energy and saves your money.
- Thermal expansion valves: The valve releases more refrigerant when there is a requirement of more cooling and release less when less requirement of less cooling. This saves your energy and money.
