It is assembled and commissioned in the factory and meets the relevant condition coefficients of performance. 3.2 Standard conditions of cold source system One or a set of operating conditions for the cold source system specified in this document that establish a comparable benchmark. Note: Standard conditions include the conditions specified in Table A.1 and the IPLVS condition in Table A.2. 3.3 Coefficient of performance of cold source system COPS Under specified standard conditions, the ratio of the cooling capacity of the cold source system to its total input electrical power, expressed in the same units. Note: The unit is kilowatt per kilowatt (kW/kW). 3.4 Integrated part load value of cold source system IPLVS A single numerical value representing the part-load efficiency of the cold source system, calculated by weighting the coefficients of performance at part-load conditions under specified standard conditions based on the cumulative load percentages under various load conditions. Note: The unit is kilowatt per kilowatt (kW/kW). 3.5 External head of cold source system The differential pressure between the supply and return water for the chilled water side of the cold source system, after overcoming the system's own resistance, that can be used to overcome the fluid flow resistance in user equipment and the pipe network. Note: Abbreviated as "external head". 3.6 Working pressure of cold source system The pressure endured by equipment, pipelines, and components during normal operation of the cold source system. 4 Model Designation The method for compiling the model designation of the cold source system may be determined by the manufacturer. However, the model should reflect the nominal cooling capacity, nominal input power, nominal condition coefficient of performance, integrated part load value, working pressure, nominal external head, and nominal chilled water flow rate of the cold source system. 5 General Requirements 5.1 Equipment for the cold source system shall be reasonably selected based on factors such as building scale, usage characteristics, and performance requirements, and shall comply with the following provisions: a) The energy efficiency of chillers should not be lower than energy efficiency grade 2 as specified in GB 19577; b) Pumps shall be variable speed pumps. Pump motors should preferably be variable frequency motors. The energy efficiency of pumps shall not be lower than energy efficiency grade 2 as specified in GB 19762. The efficiency of pump motors shall not be lower than energy efficiency grade 2 as specified in GB 18613; c) The cooling performance, noise, energy efficiency, and drift water rate of cooling towers shall comply with the relevant provisions of GB/T 7190 (all parts); d) The rated working pressure of equipment such as chillers and pumps, and pipelines and accessories, shall not be lower than the working pressure of the cold source system;
