Water chilling(heat pump) packages using the vapor compression cycle—Part 1:Water chilling(heat pump) packages for industrial & commercial and similar application
1 Scope
This Part specifies terms and definitions, types and basic parameters, requirements, test methods, inspection rules, marks, package and storage of motor-operated packages using vapor compression refrigeration cycle for industrial & commercial and similar application.
This Part is applicable to water chilling(heat pump)packages (over 50kW cooling capacity) for centralized air conditioning or process and is also applicable to packages used to prevent freezing caused by outdoor air temperature dropping or used as refrigerating (heating) packages. Packages driven by motor (diesel engine or gas engine) or turbine engine (steam turbine or combustion gas turbine) could also refer to this Part.
This Part is not applicable for drinking water and beverage or used as industrial packages, which do not use water as the refrigerating (heating) agent.
