Explanation and conversion of the unit for the heat load Q of heat exchangers
Thread Content
Hello everyone: What is the unit of the heat load Q for heat exchangers? Is it KJ/h or KW? Here, KJ stands for kilojoules, but what does KW stand for – kilowatts or kilocalories? So how is the relationship between these two converted? Thank you
The watt is a unit of work, while the joule is a unit of heat; these two cannot be converted into one another, right? It can only be a conversion between cards and joules, right?

KW stands for kilowatts; the denominator already has a unit of time. Brother, read the material carefully.
KW=kJ/s is the unit of power; kJ is the unit of work – they are not the same thing.
1 cal = 4.186 J 1 W = J/S 1 KCal/h = 1.163 W
One is a unit of power, and the other is a unit of work; the two cannot be interchanged. 1 kilocalorie = 4,185.851820846 joules； 1 joule = 0.00023889999999997 kilocalories (kcal) ； The definition of watt is 1 joule per second (1 J/s), that is, the rate at which energy is converted, used, or dissipated per second (measured in joules). 1 kilowatt = 1000 watts.
1kcal/h = 1.163w 1kcal/h = 4.187kj
