Description:GB4706.1-2005 of this chapter with the following contents:
GB4706 the provisions of this part of the household and similar use of heat pump, air conditioner and dehumidifier.
this section applies to the rated voltage not exceeding 250 v, single phase instruments other appliances does not exceed the rated voltage of 600 v, equipped with a motor - compressor and fan coil heat pump room (including life) with hot water heat pump, air conditioner and dehumidifier.
Not as general family expenses, but there is still a danger to the public, such as in shops, light industry and farms used by non-specialists instruments also belong to the scope of this section.
this section applies to the use of flammable refrigerant heat pump, air conditioner and dehumidifier. 3.121 the definition of a flammable refrigerant is presented.
the instruments may be composed of a factory or more factory production of components. If the offer is more components, and these separate group Thing to use, then the technical requirements of this international standard should be based on the assembly together of the component USES.
note 1: in GB4706.17 gives the definition of "motor - compressor", it refers to a totally enclosed motor - or semi-closed compressor motor - compressor.
note 2: in ISO5149 refrigerants security requirements are given, in addition, in GB4706.12 lives with hot water heat pump is used to store is given Hot water container requirements.
this section does not consider 3.121 definition of A1, A2 or A3 chemicals outside of class.
note 3: the provisions of this section the use of the special requirements of flammable refrigerants. Unless this part have special requirements (including appendix), refrigerant see ISO5149 safety requirements.
ISO5149: the following terms related to this part of the 1993:
--, chapter 3, apply In all the appliances and equipment design and structure of the system.
--, chapter 4, the "similar purposes", such as commercial and light industry equipment and the use of the system requirements.
--, chapter 5, for similar purposes ", such as commercial and light industry equipment and system to run the program (procedures).
the auxiliary heater (only refers to the heater design as part of the appliance assembly, controller is installed inside the appliance), or any of its other independent installation Are in the scope of this part.
note 4: must pay attention to the following situation:
- for ready to use on the car, ship or aircraft instruments, may require additional requirements;
- for pressure equipment, may require additional requirements;
- in charge of labor security of the national health service and is responsible for the warehousing, transportation, building structure and installation of additional requirements prescribed by the state institutions, etc.
note 5: This section does not apply to:
- IEC60335-2-88 conformity with the provisions of the humidifier with heating and cooling equipment;
- specially designed for industrial processes and equipment;
- preparing for some special conditions, for example, there is corrosive or explosive gas, dust, vapour or gas).
