# Conversion of BTUH to ton of refrigeration

## Conversion of BTUH to ton of refrigeration

(OP)
I am looking for the conversion factor to convert the BTUH into TON OF REFRIGERATION. And how could I measure the available cooling load capacity given that I had a 2 air cooled chiller with a 4 chiller compressor.Capacity of Chiller: 370 TOR each. The facility equipment we had in the factory are follows:

1. 4 air washer unit
2. 5 air handling unit
3. Cooling tunnel
4. 2 units of dehumidifier

### RE: Conversion of BTUH to ton of refrigeration

Note that it's not BTUH but BTU/hr and the conversion is 1TR = 12000btu/hr. If you know the water flowrates and temperature difference then you can calculate the tonnage by the formula Q = 0.284 x m x Cp x dT where, Q is cooling capacity in TR, m is mass flowrate in kg/s, Cp is specific heat of water (4.18 kJ/kg0C) and dT is temperature difference across the evaporator in 0C.

Alternately, you can approximately check this if you know the mass flowrate of refrigerant, the suction condition of refrigerant and the liquid parameters. Chiller manufacturers generally perform these calculations. I suggest Principles of Refrigeration and Air Conditioning by Roy J Dossat, an excellent reference for your life time.
