How is EER cooling calculated?
The EER rating for an air conditioner is calculated by dividing the BTU (British Thermal Units) rating by the wattage. For example, a 12,000-BTU air conditioner that uses 1,200 watts has an EER rating of 10 (12,000/1,200 = 10).
What is the unit of EER?
A room air conditioner’s efficiency is measured by the energy efficiency ratio (EER). The EER is the ratio of the cooling capacity (in British thermal units (Btu) per hour) to the power input (in watts). The higher the EER rating, the more efficient the air conditioner.
Is 9.7 EER good?
The average EER rating of portable AC units is about 8.5. That means buying ones below EER 8.5 is not advisable and buying those above 8.5 is quite a smart move efficiency-wise. The most energy-efficient portable AC unit (Whynter Dual-Hose) has an EER rating of 11.2.
What is EER in inverter AC?
EER or Energy Efficiency Ratio is basically an energy performance rating for air conditioners. The higher the EER, the more cooling/heating will the air conditioner provide for every watt of energy consumed.
What is EER in HVAC?
The Energy Efficiency Ratio (EER) of an HVAC cooling device is the ratio of output cooling energy (in BTU) to input electrical energy (in watts) at a given operating point. EER is normally calculated with a 95 °F outside temperature and an inside (return air) temperature of 80 °F and 50% relative humidity.
What is Iseer value?
How is ISEER calculated. ISEER is the ratio of the total annual amount of heat that the equipment can remove from the indoor air when operated for cooling in active mode to the total annual amount of energy consumed by the equipment during the same period.
Is 12.1 EER good?
12 EER rating is an excellent energy-efficiency rating for an air conditioner. Some of the best devices can even reach more than 12 EER. The best mini split air conditioners have an extremely high 12+ EER rating (check them here).
How many watts is a 1.5 ton AC?
1,500 watts
As a general rule of thumb, for AC power consumption calculation you should take, 1 ton of cooling = 1,000 watts. 1.5 ton of cooling = 1,500 watts.
What are the units of EER for air conditioners?
The units of EER are Btu/Wh. This efficiency term typically includes the energy requirement of auxiliary systems such as the indoor and outdoor fans. The heat removed and electrical power consumed for the air conditioner unit can be measured and calculated in different ways.
What is the EER of a 10000 BTU air conditioner?
For example, if you have an air conditioner with 10,000 BTU of cooling energy, and it takes 950 watts to power it, the EER is 10.53. 10000 BTU / 950 w = 10.53 EER.
What is the EER rating of a 400 watt air conditioner?
EER rating, in this case, would be 12,000BTU/1,400W = 8.57. That means that for every 1W of energy, this AC would provide us with only 8.57 BTU of cooling effect instead of 12 BTU.
What is the EER of a 1kW chiller?
If the efficiency of a chiller is rated to 1 kW/ton, then COP = 3.52 EER = 12 Cooling Load in – kW/ton
