Air Conditioner Capacity: BTU, Ton, kW, HP - Efficiency: COP, EER, SEER, HSPF, CEER

[@SmooveBee1]

1 Ton of cooling was based on 24 hour period (one ton of ice melting) and this is 12,000 BTU/Hour for 24 hours - Equivalent total Heat Energy Transfer. It takes one ton of heat to remove 288,000 Btus from the air in a day. That's the amount of Btus that must be removed to melt one ton of ice over 24 hours. Thus, a one-ton AC unit would be rated 12,000 Btus per hour.

Now it makes sense 😁😁😁😁😁, because I used to live in Malaysia and I went for new air-conditioning and asked the specialist how many "TONS" I needed for my apartment. He mocked me saying you have an apartment, not a "TRUCK" to ask about tons 😁😁😁. I was very confused because tons is the unit of refrigeration where I came from. Now I know that he was wrong

[@aircondlounge]

Haha. It is very much depending on local practices.

What is the best way to determine the energy efficiency of aircon, Weighted COP ?

[@aircondlounge]

For residential aircons, many countries have their own rating system and that’s the best one. For example, in the US, SEER for cooling efficiency and HSPF for heating efficiency. COP usually reflects the efficiency on the product design level. For actual efficiency, SEER HSPF are better indicators.

What is better to have a higher EER or CEER for a portable AC Unit

[@aircondlounge]

High EER is good for portable ACs

[@safetyalways7788]

Please how good is EER of 2.13-2.20? Also, can i use generator of 2.4kw to power 2.2kw air conditioner?

[@aircondlounge]

Hi, we need to know what measurement unit you use to get the EER. Also, a 2.2 kW air conditioner probably uses about 500-800W of power. So, a 2.4 kW generator is sufficient, given that the power is stable because modern air conditioners with a lot of electronics are more sensitive to power surge and overcurrent.

[@safetyalways7788]

Can u send me ur email address so I can send you the power specification label on my air conditioner for better clarity
