UL 399-2008饮用水冷却器

1.1 These requirements cover self-contained drinking-water coolers which employ hermetic refrigerantmotor-compressors and which are designed for connection to alternating-current circuits rated not greaterthan 600 volts in accordance with the National Electrical Code, NFPA 70. The requirements also apply towater coolers which supply both hot and cold water.1.2 These requirements do not include additional requirements applicable to equipment designed for usein hazardous locations as defined in the National Electrical Code, NFPA 70.1.3 A product that contains features, characteristics, components, materials, or systems new or differentfrom those covered by the requirements in this standard, and that involves a risk of fire, electric shock, orinjury to persons shall be evaluated using the appropriate additional component and end-productrequirements as determined necessary to maintain the acceptable level of safety as originally anticipatedby the intent of this standard. A product whose features, characteristics, components, materials, orsystems conflict with specific requirements or provisions of this standard cannot be judged to comply withthis standard. Where considered appropriate, revision of requirements shall be proposed and adopted inconformance with the methods employed for development, revision, and implementation of this standard.

This clause of part 1 is replaced by the following: This International Standard deals with the safety of the following appliances, their RATED VOLTAGE being not more than 250 V for single-phase appliances, 480 V for other appliances and 24 V d.c. for appliances when battery operated: a) REFRIGERATING APPLIANCES for household and similar use; b) ICE-MAKERS incorporating a motor-compressor and ice-makers intended to be incorporated in frozen food storage compartments; c) REFRIGERATING APPLIANCES and ICE-MAKERS for use in camping, touring caravans and boats for leisure purposes. These appliances may be operated from the mains, from a separate battery or operated either from the mains or from a separate battery. This standard also deals with the safety of ICE-CREAM APPLIANCES intended for household use, their RATED VOLTAGE being not more than 250 V for single-phase appliances and 480 V for other appliances. It also deals with COMPRESSION-TYPE APPLIANCES for household and similar use, which use FLAMMABLE REFRIGERANTS. This standard does not cover features of the construction and operation of those REFRIGERATING APPLIANCES which are dealt with in ISO standards. Appliances not intended for normal household use but which nevertheless may be a source of danger to the public, such as appliances intended to be used by laymen in shops, in light industry and on farms, are within the scope of this standard. As far as is practicable, this standard deals with the common hazards presented by appliances which are encountered by all persons in and around the home. However, in general, it does not take into account a) the use of appliances by young children or infirm persons without supervision; b) playing with the appliance by young children. Attention is drawn to the fact that - for appliances intended to be used in vehicles or on board ships or aircraft, additional requirements may be necessary; - in many countries, additional requirements are specified by the national health authorities, the national authorities responsible for the protection of labour, the national authorities responsible for transportation. This standard does not apply to - appliances intended to be used in the open air; - appliances designed exclusively for industrial purposes; - appliances intended to be used in locations where special conditions prevail, such as the presence of a corrosive or explosive atmosphere (dust, vapour or gas); - appliances incorporating a battery intended as a power supply for the refrigeration function; - appliances assembled on site by the installer; - appliances with remote motor-compressors; - motor-compressors (IEC 60335-2-34); - commercial dispensing appliances and vending appliances (IEC 60335-2-75); - commercial ice-cream appliances.

BS PD CEN/TR 14739-2004家用冰箱和冷藏箱中可燃制冷剂的风险评估方案

The document gives a scheme for carrying out a risk assessment for flammable refrigerants in case of householdrefrigerators and freezers with refrigerants of group A3 according to EN 378-1, taking into consideration asealed system and a refrigerant charge of not more than 150 g. Sealed systems are refrigerating systems inwhich all refrigerant containing parts are made tight by welding, brazing or similar permanent connection.NOTE For risk assessment the method with flow diagrams is selected, because these are helpful for checking thepossible ignition of the whole appliances and to estimate the probability of ignition. It takes EN ISO 12100, EN 1050,EN 1127, EN 60335-2-24/A53, E DIN 7003 into consideration.At least the probability of deflagration is the product of multiplication of the probability of defects of differentcomponents and the probability for the presence of explosive atmosphere and the probability for the ignitionsources.
