Chilled-Warm-Hot Drinking Water Dispensers:

The Energy Efficiency Standards and Marking Methods of the Energy Conservation Label for Cold/Warm/Hot Water Dispensers was announced with document number Neng-Ji-Zi No. 10805000040 and became effective on March 25, 2019.

I. The applicable scope, energy efficiency test conditions and methods and energy efficiency standards for certification of the energy conservation label for cold/warm/hot water dispensers (hereinafter referred to as ‘dispensers’) should comply with the following regulations:
(I) Applicable scope: dispensers that comply with the National Standards of the Republic of China (CNS): CNS 13516 or those recognized by relevant competent authorities
(II) Energy efficiency test conditions and methods: measure the following values according to CNS 13516:
1. Rounding off to the third decimal point is adopted for calculation of the standby loss per 24 hours (E24(kWh)).
2. The average temperature of the hot water system per 24 hours (Th(°C)), that of the cold water system per 24 hours (Tc(°C)), and ambient temperature (Tamb(°C))
3. Rounding off to the first decimal point is adopted for calculation of the actual measured volumes of the hot and cold water storage tanks (liter). The volume of each storage tank should be more than 95% of the marked value.
(III) Rounding off to the third decimal point is adopted for calculation of energy consumption (E). The equation is as follows:
E=0.117×(V1×K1 +1/3 V2×K2)+1.050
K1: (Th-Tamb)/(100(°C)-Tamb ); rounding off to the third decimal point is adopted for calculation of K1.
K2: (Tamb-Tc)/Tamb; rounding off to the third decimal point is adopted for calculation of K2.
V1: rounding off to the first decimal point is adopted for calculation of the marked value of the volume of the hot water storage tank (liter).
V2: rounding off to the first decimal point is adopted for calculation of the marked value of the volume of the cold water storage tank (liter).
(IV) The actual measured standby loss value per 24 hours should not be greater than the marked value. Also, both the actual measured value and the marked value should not be greater than the energy consumption baseline value.
II. The energy efficiency rating labeling mark for dispensers shall comply with the following:
(I) The name and address of the user must be clearly marked on the product or package.
(II) If the user is an agent, the name and address of the manufacturer must be clearly marked on the product or package as well.
(III) The product itself and the catalog should display the standby loss per 24 hours.
