air conditioner tonnage calculation formula

The following are the major factors affecting the efficiency and performance of an air conditioner and directly impacts the power consumption of air conditioner. Number of Units consumed = (1172/ 1000) kW x 10 hrsĮlectricity bill = Number of units consumed x Rate per unit Online electricity bill calculator for AC Factors affecting the efficiency of an air conditioner Power consumed can be noted from the table above or from the brochure or nameplate details of the air conditioner. Number of Units consumed = (Power consumed in kW) x (Operation Hours) Lets calculate the power consumed by a 1.5 ton 5 star rated split a/c operated for 10hrs. Bill and consumption calculationįrom the above table, energy consumption can be calculated as follows: The actual power consumption varies slightly. Note: All the above are estimated values. Therefore 288000, when divided by 24, gives 12000Btu, which is equal to one ton. That is the amount of heat required (288,000 Btu) to melt one ton of ice in a 24-hour period. One ton is equal to 12,000 Btu per hour (3.517 kW). Understanding Tonnage of ACĪir conditioning units are rated in tons. Power fluctuation diagram for Inverter and Non-inverter AC. Also, inverter ACs are less noisy than conventional ones. Each time it turns on, it consumes 6-8 times its rated current during start. It can either run at the full speed or stop to zero. But the conventional AC or the non-inverter AC cannot control its speed. Once the required temperature is attained, the speed of the compressor motor is lowered. The key difference between an inverter and non-inverter air conditioner is that an inverter air conditioner is capable of controlling the speed of its compressor motor. Inverter ACs are becoming much popular in the market today. Difference between Inverter AC and Non-inverter AC It is fixed in the slot made in the wall or window sill. It is a single unit containing the evaporator, condenser and compressors all together. It is the most commonly used type of residential air conditioner. The coolant is circulated between the indoor and outdoor units using copper pipes. The evaporator unit is placed inside the room and condenser-compressor unit combination is placed outdoors. Split ac consists of an indoor unit and an outdoor unit. The cooling unit (evaporator, condenser, and compressor) is placed outdoors. Here we will discuss on the following types of air conditioners:Ĭentral air conditioners deliver cooled air to the through a system of supply and return ducts.
