20、 BSI EN 13203-2:2006 (E) 4 1 Scope This European Standard is applicable to gas-fired appliances producing domestic hot water. It applies to both instantaneous and storage appliances; waters-heaters and combination boilers that have: heat input not exceeding 70 kW, and hot water storage capacity (if
21、any) not exceeding 300 l. In the case of combination boilers, with or without storage, domestic hot water production is integrated or coupled, the whole being marketed as a single unit. This European Standard EN 13203 is formed in two parts, which cover two aspects of domestic hot water production.
22、EN 13203-1 sets out in qualitative and quantitative terms the performance in delivery of domestic hot water for a selected variety of uses. It also gives a system for presenting the information to the user. This first part compliments EN 26, EN 89 and EN 625. The present European Standard EN 13203-2
23、 sets out a method for assessing the energy performance of the appliances. It defines a number of daily tapping cycles for each domestic hot water use, kitchen, shower, bath and a combination of these, together with corresponding test procedures, enabling the energy performances of different gas-fir
24、ed appliances to be compared and matched to the needs of the user. 2 Normative references The following referenced documents are indispensable for the application of this European Standard. For dated references, only the edition cited applies. For undated references, the latest edition of the refere
25、nced document (including any amendments) applies.

26、uropean Standard, the following terms and definitions apply. 3.1 control cycle time cycle for keeping components and/or the tank (if any) of the domestic hot water circuit at predetermined temperature level, consists of an ON duration time during which the heating of the domestic hot water (by gas e

29、 NOTE Qnw is expressed in kilowatt (kW) 3.5 off mode state of an appliance, selected by the user, in which domestic hot water can not be provided 3.6 stand-by mode operating state in which the appliance can provide domestic hot water at any time. In the case of an appliance with a control cycle for
30、keeping components and/or the tank (if any) of the domestic hot water circuit at predetermined temperature, level no tapping is made 3.7 summer mode conditions during which the appliance supplies energy only for the production of domestic hot water 3.8 tank reservoir for domestic hot water 3.9 usefu

33、old water temperature: (10 2), in C; cold water pressure: (2 0,1), in bar; 1 The manufacturer is the organisation or company which assumes responsibility for the product.

34、ambient air temperature: (20 3), in C; electrical supply voltage: (230 2), in V. 4.2 Measurement uncertainties Except where otherwise stated in the clauses describing the tests, the uncertainties of measurements carried out shall be not greater than the maximum uncertainties indicated below. These u
35、ncertainties correspond to two standard deviations. The laboratory evaluates these standard deviations taking account of the various sources of uncertainty: contribution from the instrument, repeatability, calibration, ambient conditions etc.: water rate: 1 %; gas rate: 1 %; time: 0,2 s; temperature
36、s: ambient: 1 C; water: 0,5 C; gas: 0,5 C; mass: 0,5 %; gas pressure: 2 %; gas calorific value: 1 %; gas density: 0,5 %; electrical energy: 2 %. The stated measurement uncertainties relate to individual measurements. For measurements that combine a number of individual measurements, smaller uncertai
37、nties on the individual measurements may be necessary to ensure a total uncertainty within 2 %. 4.3 Test conditions 4.3.1 General Except where otherwise stated, the appliance is tested under the following conditions. For combination boilers the tests are carried out only in summer mode. 4.3.2 Test r
38、oom The appliance is installed in a well-ventilated, draught-free room (air speed less than 0,5 m/s). The appliance is protected from direct solar radiation.

39、upply For the tests: the domestic water pressure is the static inlet pressure under dynamic conditions measured as close as possible to the appliance; the inlet and outlet temperatures of the domestic water are measured in the centre of the flow and as close as possible to the appliance. The inlet t
40、emperatures are measured immediately upstream of the water inlet connection. Except where otherwise stated, the outlet temperatures are measured immediately downstream of the outlet connection or, in the case of an appliance with spout delivery, by means of an immersed temperature measuring device,
41、e.g. a u-tube fitted at the outlet of a tube of the same length as the minimum length of the spout normally supplied by the manufacturer. The hot water temperature is measured with a rapid response thermometer. “Rapid response thermometer“ means a measuring instrument with a response time such that
42、90 % of the final temperature rise, from 15 C to 100 C, is obtained within about 1 s, when the sensor is plunged into still water. 4.3.4 Steady state Steady state operating conditions shall be regarded as established when the rate of change of the domestic hot water temperature at the appliance outl
43、et has become less than the temperature fluctuation at constant water rate ?T2 according to 3.8 of EN 13203-1:2005. 4.3.5 Initial adjustment of the appliance The appliance is installed in accordance with the manufacturers instructions. The heat input shall be adjusted to within 2 % of the nominal do
44、mestic hot water heat input under the conditions prevailing at the time of the test. The delivered water temperature at the appliance outlet is defined as follows (see Figures A.1.1 and A.1.2): a) appliances with an adjustable temperature: the tests are carried out at a temperature not greater than
45、65 C, with a minimum temperature increase equal to or greater than 45 K above water inlet temperature; b) appliances with a fixed temperature: the tests are carried out at the temperature specified by the manufacturer, with a minimum temperature increase equal to or greater than 45 K. The same condi
46、tions of initial adjustment stated by the manufacturer are used for all the tests. These conditions are included in the test report. 4.3.6 Electrical supply The appliance is supplied with the nominal voltage or a voltage included within the range of nominal voltages.

48、1 General All patterns define a 24 h measurement cycle and within that cycle the starting times and the total energy content (in kWh equivalent of hot water tapped) of each draw-off are defined. Furthermore, the draw-off can be characterized in two ways, either: a) “Basin” type draw-off (bath, dishw
49、ash) versus “continuous flow” draw-offs (shower, handwash etc). The aim of the former is to arrive at an average temperature of the tub, so all supplied energy can be considered useful from the very beginning of the draw-off (minimum useful temperature increase is 0 K). The latter start to be useful only from a certain temperature (minimum useful temperature increase is 15 K lower than t
