While converting refrigeration ton to kw, have you asked yourself?
Why 1 RT (Refrigeration ton) = 3.51kw? this conversion is most popular in the HVAC industry but do you know why 1 RT = 3.51kw?
at the end of this post you will know the reason, please let me know your comments.
as we know Q = m * L
m = mass
L = 335 kj/kg for water
Q = 1 US ton * 335 ( 1 US ton = 2000lb= 907.185 kg)
Q = 907.185*335*1000 (multiplied by 1000 to convert kg/kg to j/kg)
Q = 303.90 * 10^6
Q = 303.90 * 10^6 /24*60*60 ( 24 hours)
Q = 3.517 kw or 210 Kj/min
Hence 1 RT = 3.517 kw
