Centrifugal water chillers

JIS B8621-2011 发布历史

This Japanese Industrial Standard specifies the centrifugal water chillers (hereafter referred to as "refrigerating machines") which perform cooling or heating of water by the refrigerating cycle composed of a centrifugal compressor, a compressor driving motor, an evaporator, a water cooled condenser, auxiliary refrigerant pipings and a control system, the refrigerating capacity of which, in accordance with the standard rating of this Standard, is 350 kW or greater. Further, this Standard applies to the refrigerating machines which use an incombustible and non-toxic refrigerant whose saturation vapour pressure is not more than 3 MPa at the temperature of 35℃, and does not apply to those which perform cooling and heating by other brine than water or which supply water for drinking. NOTE ：Through the main text, the term "pressure" means a gauge pressure.
