Transcription

1 HIGH EFFICIENCY CENTRIFUGAL CHILLER Model type series in this catalogue is our model code. CR417EA

2 All models' COP are above in this series! Welcome to the low-carbon society Model RTBF Type Series High Efficiency Centrifugal Chiller Lower Operation Expense & CO Emission Compare to our previous model, the operation expense is 36% lower! And the CO emission is 4% lower Centrifugal chiller annual power cost estimates Coercial facility air conditioning(500usrt annual operation) Compare with our Previous model of a decade ago Centrifugal chiller annual CO emission Coercial facility air conditioning(500usrt annual operation) Compare with our company 10 years earlier model Annual power cost (1000 JPY) 10,000 9,000 8,000 7,000 6,000 5,000 4,000 3,000,000 1,000 0 Basic cost difference Annual cost (Cost of previous model) 36% Lower (RTBF type) Annual CO emission % Lower 0 (our company 10 years earlier model) (RTBF type) Calculation conditions Centrifugal chiller power cost calculation is based on annual operation, 14h/d coercial facility load rate. The power cost calculation is according to the high voltage electricity contract signed with TEPCO at Apr The CO emission calculation is based on the unit 0.5kgCO/h. which was modified at Mar Newly Developed High Efficiency Compressor Compressor compact design by using -stage compression and speed-up Gear. Using changeable -stage suction vanes for better partial load performance. A simple motor structure with few piping for a better quality. nd stage impeller nd stage suction vane Motor 1st stage suction vane Speed up Gear 1st stage impeller Very Compact Design Compare to The Previous Model To achieve a small & light-weight design by doing many tests on shape of parts, material & manufacturing process. The outline dimension compare to the Previous model Height 19% smaller The Previous model RTCSSL050(500USRT) The new model RTBF050(500USRT) Width 11% smaller Production weight 35% lighter Length 14% smaller Side view Front view

3 This is our standard model in future. The simple structure, compact and high efficiency chiller. Using New Refrigerant HFC45fa Excellent refrigerating cycle performance to make a high efficiency A smaller theoretical flow rate than HCFC 13 Compare to HCFC13, the required HFC45fa theoretical flow rate is smaller under the same cooling capacity, thus we can make a smaller compressor. A better performance than HFC134a Compare to HFC134a, the HFC45fa is a refrigerant that has higher theoretical cycle performance & energy efficiency. Minor environmental burden The HFC45fa's ODP(Ozone Depletion Potential) is zero. Moreover, compare to HFC134a, the HFC45fa has smaller GWP(Global Warming Potential), shorter atmospheric lifetime & smaller impact to the environment. ODP(Ozone Depletion Potential) GWP(Global Warming Potential)100years ,000 1,00 1,400 1,600 1,800 ODP:0.0 Atmospheric lifetime:1.3years HCFC13 GWP:77 Atmospheric lifetime:14years ODP:0 HFC134a GWP:1430 ODP:0 Atmospheric lifetime:7.6years HFC45fa GWP: Atmospheric lifetime(year) A low pressure refrigerant, easy operation & management. HFC45fa is a refrigerant that no need to apply the high pressure gas regulation. =Need=No need Item Remarks Specified material Substitute HCFC13 HFC134a HFC45fa High pressure gas safety regulation applicable liquid gas combination type specified equip. Operation certificate operation certified person Installation Operation management Install license Install declare check maintenance check self check Declaration of hazard prevention regulation Standard of the machine room apply & declare by customer factory check check by government every 3 years every year ventilation, safety valve exhaust pipe are required. safety distance Appropriate settings are made by following the Guideline on Centrifugal Chillers issued by the Japan Refrigeration and Air Conditioning Industry Association (JRAIA). High safety HFC45fa is noncombustible. And low toxic, the admissible concentration is ppm. Minor environment burden & easy to use, it's the refrigerant HFC45fa. 3
