We operate in the refrigeration sector exporting our CO² range of products worldwide. While intended as a single number means of comparing individual chillers and not as an annual energy calculation tool, IPLV can be used for a quick estimate of chiller annual energy cost by using the formula of Annual Energy Cost = IPLV x $/kwh x average chiller load x operating hours but this should be viewed as only a rough estimate. I am figuring a ¾ pipe will give me about 8 GPM to the coil I have found a First Co coil that with a six row config will provide 48. Cooling Water Systems 1. The 100 gpm returning from the building feeds back into the primary pump, completing the circuit. Within some problem domain, the amount of mass remains constant --mass is neither created nor destroyed. Keep in mind Vermont is colder than North Carolina and your building's insulation is excellent to poor. 4 gpm) and if (delta T=12 F') ----- 1TR=2 gpm - and this is the most common degrees used in chillers but it your loads exceeds 1000TR you will use deltaT= 12 F' directly. The equivalent ton on the cooling tower side actually rejects about 15000 Btu/h due to the heat-equivalent of the energy needed to drive the chiller's compressor. For all chiller types, ARI rates the evaporator conditions as 54?F entering and 44?F leaving chilled water (which corresponds to 2.
