Help needed: conversion of cooling capacity for screw refrigerators
Thread Content
As shown in the figure, I would like to ask the experts how to convert the cooling capacity into joules or kilocalories? Thank you
The unit is “kilocalorie” (kcal or C), also known as “large calorie”; 1 kilocalorie equals 1000 calories, which is approximately 4186 joules. 1 kilowatt-hour = 1 kilowatt × 1 hour = 1000 watts × 3600 seconds = 3,600,000 watt-seconds = 3,600,000 joules; therefore, 1000 watts = 860 kilocalories, which means 1 watt = 0.86 kilocalories. 109KW × 0.086 ten thousand kcal/KW = 9.374 ten thousand kcal
1KW = 861 kcal, 109KW = 9.3849 kcal
1 Kw = 860 kcal. The nominal cooling capacity of your chiller is calculated as: 109 kW x 860 kcal = 93,740 kcal
