Single point power supply: 460V / 3PH / 60HZ: Connections: 2 @ series 16 male per conductor: Min. Convert result into tons of chiller capacity. Electricity Costs per kWh = € 0,18. 9°C). 9-1. forced draught (using fans) natural draught Jul 22, 2022 · The chart tells us that a 2. Even with the potential concerns, variable flow in the condenser water system is still a viable option and can further reduce the overall kilowatt per ton of chiller water produced throughout the entire range of plant operation. However, in both cases, the specific input power of the chiller deteriorates from 0. b. The compressor power can be measured by a portable power analyser which would give read-ing directly in kW. 3. For example, a chiller rated at 0. 93 r 134a ygsdsbj3 1,750 6,482 1. Here you have it: 1. FEMP has calculated that a 500-ton water-cooled centrifugal chiller meeting the required 0. Without accounting for the cooling tower and pumps, the average cooling cost was $0. 9. 91 kWh to 1234. 200 Ton Portable Air Cooled Chiller. 5 tons of refrigeration is equal to kW. Let's calculate Chilling duty (Qa) of the heat exchanger. thank you! a. That means higher repair and/or replacement bills and expensive downtime. Energy Efficiency Rating (EER): IPLV: 19. Evaporative cooling towers, like the ADVANTAGE Power Tower® Series, provide cooling by evaporating a small amount of the recirculated process water flow. Tonnage = 500 (GPM) × 10 (ΔT) × 500 / 12,000 = 208. chiller model capacity (tons) consumption (btu/ton hr) unit cop (per hhv) refrigerant ygpbpbh1 550 6,472 1. For a simple solution, we have prepared a TR to kW calculator that automatically calculates this for you. 698kW/Ton to 0. Jan 9, 2024 · The wattage of your heat pump correlates with the tonnage and BTU output. • Leaks or overflows 2,593. Once you know this equivalence, determining the cooling capacity from the specifications sheet should be a breeze. ty jq uq qx xs tg nk nj yc ng
