# How to calculate ton of refrigeration for chiller

A much less common definition is: 1 tonne of refrigeration is the rate of heat removal required to freeze a metric ton (1000 kg) of water at 0°C in 24 hours. Based on the heat of fusion being 333.55 kJ/kg, 1 tonne of refrigeration = 13,898 kJ/h = 3.861 kW. Thus, 1 tonne of refrigeration is 10% larger than 1 ton of refrigeration.How to Calculate Chiller Tonnage - Formula. The final step to convert your answer into tons of chiller capacity is to divide your result, Q (BTUs per hour), by 12,000 (the number of BTUs in one ton of cooling capacity). This will give you, in tons per hour, the chiller capacity that is needed to handle the process heat load.Cooling Load is calculated in 4 main groups. 1- Heat losses on the wall, floor, and ceiling surrounding the cooled volume. 2- Hot air entering the cold storage while the cold room door is open. 3- Heat load from stored products. 4- Heat from the heat sources inside the cold storage (People, Lighting, engine, etc.)
