Gas-fired overhead radiant heaters fall within the scope of the Gas Appliance Directive, 90/396/EEC and as such are required to bear the CE mark according to the appropriate Regulations. This European S

18、tandard has been prepared with the support of CEN/PC 3, now replaced by the Sector Forum Gas, with the intention of harmonising national installation and ventilation requirements for heating systems, consisting of one or more individual overhead radiant heating appliances. The scope of the Gas Appli

19、ance Directive does not indicate a maximum value for the heat input of an individual gas appliance. However, in the scope of EN 416-1: 1999 and EN 419-1:1999 the heat input of an individual radiant heater is limited to 120 kW (based on the net calorific value of the appropriate reference gas), this

30、 installed nominal heat input of the radiant heaters. 4.2 Evacuation of the products of combustion 4.2.1 General The products of combustion from radiant heaters shall be evacuated out of the installation room to the outside of the building. For type Aappliances it is done by non-direct evacuation of

31、 the products of combustion. The products of combustion leave the appliance, mix with the air in the installation room and leave the building. This ventilation may be achieved by any of the three following different means: a) thermal evacuation of the products of combustion/air mixture; b) mechanica

32、l evacuation of the products of combustion/air mixture; c) natural air change. The following sub clauses describe the detailed calculations to be performed for all three ventilation methods (see Annex A). 4.2.2 Ventilation by thermal evacuation 4.2.2.1 The air of the room mixed with the products of

33、combustion shall be evacuated above the radiant heaters, if possible near the ridge by means of exhaust air openings. 4.2.2.2 Exhaust air openings shall be constructed and located so that suction of the exhaust air shall not be disturbed by wind influence. European or National regulations and guidel

34、ines may prescribe the location of exhaust air openings. 4.2.2.3 Shut down devices and restrictors at exhaust air openings are permissible if an automatic safety device ensures opening of the devices/restrictors for the safe operation of the appliances. Otherwise exhaust air openings shall not be re

35、stricted or closed.EN 13410:2001 (E) 5 4.2.2.4 The number and arrangement of the exhaust air openings depend on radiant heater arrangement and room geometry. The horizontal distance between a radiant heater and an exhaust air opening shall not exceed six times the exhaust air opening height (measure

36、d to the centre of the opening) for wall openings and three times the exhaust air opening height (measured to the centre of the opening) for roof openings. 4.2.2.5 Ventilation by thermal evacuation is sufficient if 10 m/h of exhaust air per kW of operating heat input are ventilated out of the instal

37、lation room. 4.2.2.6 When applicable, the exhaust air flow rate shall take into account any exhaust air flow rate required for other purposes. The size and number of openings is then computed based on the higher of these air flow rates. 4.2.2.7 The calculation methods are as follows. a) Calculation

38、of the necessary exhaust air volume rate. V tot= Q NB L where: V tot is the total necessary exhaust air volume rate in m/h; Q NBis the total operating heat input of all radiant heaters in kW; L is the specific exhaust air rate ( 10 m/h)/kW. b) Calculation of the evacuation velocity at the exhaust ai

39、r opening. The evacuation velocity may be taken from Figure 1, where: h is the vertical distance from the centre of the inlet opening to the centre of the exhaust opening in m; v is the evacuation velocity in m/s; t is the temperature difference t 2 t 1in o C; where t 1 is the lowest outdoor tempera

Only fans with a steep characteristic shall be used. 4.2.3.2 It shall only be possible to oper

43、ate the radiant heaters when the exhaust air evacuation is assured. 4.2.3.3 The number and arrangement of the fans depend on radiant heater arrangement and room geometry. The horizontal distance between a radiant heater and a fan shall not exceed six times the fan mounting height (measured to the ax

44、is of the fan) for wall mounted fans and three times the fan mounting height (measured to the axis of the fan) for roof mounted fans. The fans shall be installed above the radiant heaters, if possible near the ridge. 4.2.3.4 Ventilation by mechanical evacuation is sufficient if 10 m/h of exhaust air

45、 per kW of operating heat input are ventilated out of the installation room. 4.2.3.5 When applicable, the exhaust air flow rate shall take into account any exhaust air flow rate required for other purposes. The fan capacity is then computed based on the higher of these air flow rates. 4.2.3.6 The ca

46、lculation methods are as follows. a) Calculation of the necessary exhaust air volume rate: V tot= Q NB L where: V tot is the total necessary exhaust air volume rate in m/h; Q NBis the total operating heat input of all radiant heaters in kW; L is the specific exhaust air rate ( 10 m/h)/kW. b) The tot

47、al fan capacity, whether provided by one or more fans, shall be at least equal to the value of V totas computed in a). 4.2.4 Ventilation by natural air change Gas-fired radiant heaters may be operated without any special exhaust system, if the exhaust gases are discharged to the outside atmosphere b

48、y a sufficient natural air change in the installation room. No provision for thermal or mechanical ventilation is needed in the following particular cases: - buildings with natural air change greater than 1,5 volumes per hour; - buildings with density of operating heat input not greater than 5 W/m.E

49、N 13410:2001 (E) 8 4.3 Air supply Air supply openings are required to admit air and shall be located below the radiant heaters. Exceptions are possible if the air supply openings are between the individual heaters and their location has been planned after proper evaluation of the air flow.
