The required cooling capacity for a room air conditioner depends on the size of the room being cooled — room air conditioners generally have cooling capacities that range from 5,500 Btu per hour to 14,000 Btu per hour. A common rating term for air conditioning size is the “ton,” which is 12,000 Btu per hour.

Which AC mode is best for cooling?

Cool mode” should be used during hot and dry seasons, while the aircon “dry mode” is more appropriate for humid seasons that aren’t necessary hot and warm in temperature. Utilizing dry mode more often is also better for the environment.

What makes the air cool in AC?





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.

How cool can an air conditioner cool?

A residential AC can lower the indoor temperature a max of 20°F. The heat transfer capacity of an air conditioner can remove enough heat from a house to drop the temperature by 20°F. It can be set to do less, but it can’t be made to do more.

How do I find the cooling capacity of my air conditioner?

How is HVAC capacity calculated?

  • Divide the square footage of your house by 500.
  • Multiply this number by 12,000 BTUs.
  • Add to that number the additional heat generated by windows, workers or areas such as kitchens.

Why is my AC running but not cooling?





If you’re experiencing AC not cooling while the system is powered on, you could have a clogged or blocked coil. Unfortunately, a wide variety of debris can find its way into this equipment, including grass, dirt, and other contaminants. This can result in a serious clog, which can lead to a system malfunction.

Which AC mode is best in summer?

This North-Indian summer can be best survived by setting your AC on the ‘cool mode or default mode‘ in which the air conditioner runs as per the temperature setting and fan speed at which it has been set. This setting is ideal for the most efficient cooling in dry heat.

What is the working principle of AC?

AC operating principle of the air conditioner. An air conditioner collects hot air from a particular room, processes it into itself with the help of a refrigerant and a series of coils, and then releases cool air into the same room where the hot air was originally collected.

How do you create cold air?

Let the air in



Keep your windows, doors and blinds shut during the day to avoid hot sun beating down into your house. Then, during the evening, open your windows and place one fan facing out of your window, so it pushes the heat out. Use a second fan, placed inwards, to circulate cool air into the room.

Which gas is used in AC?

R22 with a molecular formula of CHCLF2 is the most widely used refrigerant for the Air-conditioners. It constantly changes its state(Solid, Liquid and gas) at different temperature.

What is cooling capacity of 1.5 ton AC?

Cooling Capacity:



Similarly, if we consider 1.5 Ton AC, the cooling capacity is 18000 BTU/hr, which means 5275 Watt approx.

What is cooling capacity in watts?

Central Air Conditioners: Cooling Function

Central air conditioners use 1,000 watts per one ton of cooling capacity. For a 2,000 square foot home with standard-height ceilings, you’ll need about 3.5 tons of cooling power. This capacity of air conditioner will use about 3,500 watts per hour.

What is meant by 1 ton AC?

The BTU for air conditioners ranges from 5000 to 24000 BTUs and 12000 BTUs is equal to 1 ton.

Which is better 3-star or 5 star AC?



The 5-star ACs are more energy-efficient than a 3-star AC unit. The electricity consumption of a 5-star AC (1.5 tons) is approximately 1.5 units per hour, whereas a 3-star AC (1.5 tons) consumes 1.6 units every hour.

What is 3-star and 5 star in AC?

Overview of the Star Rating System

The higher the number of stars, the more efficient the appliance will be. The range of the star rating system is 1 star to 5 stars. So, there will be a difference between a 3-star AC and a 5-star AC. In simple words, a 5-star AC would be more power-efficient than a 3-star AC.

Which AC is suitable for 12×12 room?

According to Energy Star, a 12×12′ or 144 sqft room requires 5,000 BTU of cooling capacity when occupied by two persons. If the room is heavily shaded, it only requires 4,500 BTU. If the room is very sunny, it requires 5,500 BTU. For each additional person, you need to add 600 BTU.

Can a 1.5 ton AC cool two rooms?



1.5 Ton Window AC has to work more for 2 rooms. Cost part will be of 1 AC but time taken to cool the 2 rooms will be more. However O General is much efficient than other ACs . It will serve the purpose better than any other AC.

Is 1 ton AC enough?

If a Room sq ft is between 100-200 sq ft, then go for 1 Ton AC. That should do. 3. If a Room sq ft is above 201-300 sq ft, then go for 1.25 or 1.5 Ton AC.

Should I buy 1 ton or 1.5 ton AC?

1 ton ACs can provide just the sufficient bit of cooling while not going too heavy with the electricity bill. While you compare 1 ton vs 1.5 ton AC, the rule of thumb is that if you have a room which is more than 200 square metres, you should be opting for an AC with a 1.5 ton capacity.

Which is better inverter or non-inverter AC?

Inverter aircons are inherently more energy-efficient and will help you save on your monthly bills. Also, because of this energy-efficient feature, inverter aircons are regarded as an environmentally-friendly system as it uses 30-50% less energy than a non-inverter type.

What is difference between inverter and non-inverter AC?

Once a room is cool, inverter air conditioners lower the speed of the compressor motor to save energy and refrigerant required to cool the air. In comparison, non-inverter motors only run at full speed then shuts off when the room temperature reaches the desired temperature.
