Scope

Main technical content: 5.3 Performance in Use 5.3.1 Hot Water Output Performance 5.3.1.1 Water Temperature at the Hot Water Outlet The water temperature at the hot water outlet of a pipeline water dispenser should meet the following requirements: a) For heat storage-type pipeline water dispensers, the water temperature at the highest setting of the hot water outlet should not be lower than 90°C or the nominal value (whichever is higher), and the volume of water flowing at 90°C or above during a single output should not be less than 0.2L; b) For instant-heating type pipeline water dispensers, the water temperature at the highest setting of the hot water outlet should not be lower than 93°C or the nominal value (whichever is higher). 5.3.1.2 Hot Water Production Capacity The hot water production capacity of a pipeline water dispenser should meet the following requirements: a) For heat storage-type pipeline water dispensers, the hot water production capacity should not be less than 3L/h or the nominal value (whichever is higher); b) For instant-heating type pipeline water dispensers, the hot water production capacity should not be less than 18L/h or the nominal value (whichever is higher). 5.3.2 Cold Water Output Performance 5.3.2.1 Cold Water Output Temperature The cold water output temperature of a pipeline water dispenser should meet the following requirements: a) For compressor-cooled pipeline water dispensers, the cold water output temperature should not be higher than 10°C or the nominal value (whichever is lower), and the volume of drinking water output at this temperature should not be less than 0.2L during a single output; b) For electronic-cooled pipeline water dispensers, the cold water output temperature should not be higher than 15°C or the nominal value (whichever is lower), and the volume of drinking water output at this temperature should not be less than 0.2L during a single output.
