Chilled water tonhours measurement for billing
Oct 25, 2010· Hi, We are in a commercial building and are being billed perton hour for the chilled water usage on our 20ton, chilled water fed Liebert upflow A/C unit. We are trying to figure out how much we are paying for how much tonnage we are actually using in a month. Our last bill said we used 2,904 ton hours, and the amt was just shy of 500.
