Comfort fans and regulators for household and similar purposes - Methods for measuring performance 1 Scope This document specifies the performance-measuring methods of comfort fans and regulators for household and similar purposes, including conventional fans, tower fans and bladeless fans, their rated voltage being not more than 250 V for single-phase fans and 480 V for other fans, and their rated power input being less than 1 25 W. Note 1: According to the testing method, the comfort fans are classified into two groups: ——pedestal fans, table fans, wall fans, louvre fans, tower fans, bladeless fans; ——ceiling fans. Wherever applicable, the term "fan" used in this document includes its associated regulator, if any. Note 2: This document does not apply to ——safety of electric fans for household and similar purposes (GB 4706.27); ——performance of ventilating fans (IEC 60665); ——electromagnetic compatibility requirements for household appliances, electric tools and similar apparatus - Part 1: Emission (GB GB 4343.1) ——electromagnetic compatibility requirements for household appliances, electric tools and similar apparatus - Part 2: Immunity (GB/T 4343.2) ——electromagnetic compatibility - Limits - Part 1: Limits for harmonic current emissions (equipment input current ≤16 A per phase) (GB 17625.1) ——electromagnetic compatibility (EMC) - Limits - Limitation of voltage changes, voltage fluctuations and flicker in public low-voltage supply systems, for equipment with rated current ≤16 A per phase and not subject to conditional connection (GB/T 17625.2) 2 Normative references The following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. IEC 60704-2-7 Household and similar electrical appliances - Test code for the determination of airborne acoustical noise – Part 2-7: Particular requirements for fans IEC 62301 Household electrical appliances – Measurement of standby power 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. 3.1 comfort fan fan primarily designed for creating air movement around or on part of a human body for personal cooling comfort, including fans that can perform additional functionalities such as Lighting Note: A comfort fan is hereinafter also referred to by the term "fan". 3.2 conventional fan comfort fan with a propeller having two or more blades, with free inlet and outlet of air 3.3 tower fan comfort fan for use on the floor having a vertically elongated design of the cross-flow type, tangential type, centrifugal type or impeller type with a free inlet and outlet of air 3.4 bladeless fan comfort fan of any type that is not fitted with a propeller 3.5 ceiling fan conventional fan provided with a device for suspension from the ceiling of a room so that the blades rotate in a horizontal plane with the diameter of the blade not larger than 1800 mm 3.6 table fan comfort fan intended for use on a table Note: Table fans have a maximum adjustable or non-adjustable height of less than 1 200 mm. 3.7 pedestal fan comfort fan mounted on a pedestal of fixed or variable height Note: Pedestal fans have a minimum adjustable height or non-adjustable height equal to or greater than 1 200 mm. 3.8 wall bracket fan comfort fan for mounting on the wall 3.9 ceiling bracket fan comfort fan for mounting on the ceiling 3.10 louvre fan comfort fan having moving louvre which provides a continuously changing multi-directional air flow 3.11 rated fan flow rate air flow rate assigned to the fan by the manufacturer Note: The rated fan flow rate is expressed in m3 /min. 3.12 service value ratio of the calculated maximum fan flow rate [m3 /min] to the measured fan power input [W] Note: The service value is also known as the "coefficient of performance (COP)". 3.13 fan power input power input of the fan operating at its maximum flow rate, measured with the oscillation mechanism and the moving louvre, if any, turned off Note: The power inputs for other functions, such as lighting are not included. 3.14 rated voltage voltage assigned to the fan by the manufacturer 3.15 rated frequency frequency assigned to the fan by the manufacturer 3.16 maximum fan flow rate air flow rate of the comfort fan at its maximum setting [m3 /min], measured at the fan outlet with the oscillating mechanism and the moving louvre, if any, turned off 3.17 oscillating mechanism capability of the comfort fan to automatically vary the direction of the air flow while the fan is operating 3.18 fan sound power level A-weighted sound power level of the comfort fan while providing the maximum fan flow rate, measured at the outlet side 3.19 moving louvre grill provided at the air outlet of louvre fans, which is used to control the direction of the air flow by its rotation or position 3.20 equivalent sweep size diameter of bladeless fan value obtained by dividing the perimeter of the bladeless fan air outlet by 3,1 4. Note: The perimeter is obtained by measuring the length of the rope that wraps along the complete enclosure of the bladeless fan's air outlet. 4 Information provision Manufacturers shall provide the following information in the instructions: a) rated fan flow rate m3 /min (rounded to one decimal place); b) service value (m3 /min)/W (rounded to one decimal place); c) standby power consumption W (rounded to one decimal place); d) sound power level dB(A).
