How do you calculate 1 ton of refrigeration?

One ton of refrigeration is equal to 3024 kilo-calories per hour. This is 12,000 BTU/ h divided by 2.204 (pounds per kilogram) divided by 1.8 (°C to °F). Most residential air conditioning units range in capacity from about 1 to 5 tons of refrigeration or 3.5 kW ~ 17.5 kW, or 12,000 Btu/h ~ 60,000 Btu/h.

All this is further explained here. Thereof, how do you calculate tons of refrigeration?

One short ton = 2000 lb, Heat extracted = 2000 x 144/24 hr = 288000 Btu/24 hr = 12000 Btu/hr = 200 Btu/min, 1 ton refrigeration = 200 Btu/min = 3.517 kJ/s = 3.517 kW = 4.713 HP .

Beside above, how is refrigeration load calculated? Q = U x A x (Temp out – Temp in) x 24 ÷ 1000.

  1. Q= kWh/day heat load.
  2. U = U value of insulation (we already know this value) (W/m2.K)
  3. A = surface area of walls roof and floor (we will calculate this) (m2)
  4. Temp in = The air temperature inside the room (°C)
  5. Temp out = The ambient external air temperature (°C)

Correspondingly, what is the meaning of 1 ton of refrigeration?

Ton of refrigeration. It is defined as the rate of heat transfer that results in the freezing (*or melting) of 1 short ton (2,000 lb; 907 kg) of pure ice at 0 °C (32 °F) in 24 hours.

How do you calculate a ton?

Length in feet x Width in feet x Depth in feet (inches divided by 12). Take the total and divide by 21.6 (the amount of cubic feet in a ton). The final figure will be the estimated amount of tons required.
