Scope
Main technical content: This standard specifies the low-temperature waste heat resource assessment, system design, equipment selection, recovery process, and safety and environmental protection requirements for low-temperature waste heat recovery in refrigeration systems. It is applicable to low-temperature waste heat recovery projects in buildings below 200℃. The content includes: assessing the temperature, flow rate, and other parameters of the waste heat resource and calculating the energy balance; system design with safety and thermal performance requirements; equipment selection involving heat exchangers, heat pump units, etc.; recovery process including heat source analysis, direct heat exchange, and heat pump enhancement processes; and in terms of safety and environmental protection, equipment must have safety devices, ensure electrical and operational safety, and also promote energy conservation and emission reduction, manage waste, and control noise.
