hey everyone I need help calcualating how my kw's of refrigeration the new pakage unit I just installed is doing. The tradesman I work with has set it as my home work but I have lost one of my main tafe books and cant find any formulas. Can anyone please help me. All im after is the formula so I can work it out on my own. But we had 19.2 air on the coil 27.7 air off the coil with an air flow rate of 2350L/s. on heating of course. Sorry if this is in the wrong section im a newbie. Thanks for all your help
