Foreword
All technical contents of this section is mandatory.
GB 4706 "and similar household electrical appliances," it consists of several components, Part 1 General Requirements for the other parts of special
Claim.
This section is part of the 32 GB 4706. This section should be safe first and GB 4706.1-2005 "Household and similar electrical appliances
Part 1. General Requirements, "with the use.
This section drafted in accordance with the rules GB/T 1.1-2009 given.
This special section instead of GB 4706.32-2004 "heat pumps and similar household electrical appliances, air conditioners and dehumidifiers to
begging".
This section GB 4706.32-2004 The main difference is as follows.
--- Chapter 1, range of content in the "Applies to" modify the rated power "single-phase appliances rated voltage not exceeding 250V, other instruments
Pressure does not exceed 600V, equipped with an electric motor - compressors and fan coil heat pump rooms (including domestic hot water heat pumps), and air conditioners
dehumidifier. ";
--- Chapter 1, an increase in the range "of the present heat pump is also applicable to flammable refrigerants, air conditioners and dehumidifiers to .3.121
Definition of a flammable refrigerant. ";
--- Chapter 1, modified range with "Note 1. GB 4706.17 given in the" motor - definition of compressor ", which refers to a totally enclosed motor - Pressure
Or semi-closed compressor motor - compressors. ";
--- Chapter 1, increase the range of "3.121 is not considered in this section defined A1, A2 or chemical substances other than A3 class.";
--- Chapter 1, modified range with "Note 3. This section provides the use of flammable refrigerants special requirements of this section, unless there are special requirements (contained.
Appendix), the security requirements for the refrigerant, see ISO 5149.
ISO 5149.1993 in the following terms related to this section.
--- Chapter 3, applicable to the design and construction equipment all appliances and systems.
--- Chapter 4, the requirements of "similar use" (such as commercial and light industrial) appliances and systems.
--- Chapter 5, "similar use" (such as commercial and light industrial) appliances and systems operating procedures (procedures). ";
--- Chapter 1, range modify the contents of Note 4 in the third dash of "responsible for Labor and Social Security and the National Health Service is responsible for warehousing, transportation
Additional input requirements, building structures and national institutions installation. ";
--- increase in Chapter 2, "normative references." ;
--- 3.120 changed to "fan coil/air treatment assembly fancoil/airhandlingunit
It includes a forced air circulation heating, one or more functions cooling, dehumidification and filtering functions, but does not include cooling or
Assembly plant heat source.
NOTE. The device is typically designed for free air sucked into the room and discharging the same, but can work together with the pipeline. The device may
Designed to be used as an auxiliary space or into the housing of the apparatus. ";
--- Chapter 3, an increase of 3.121,3.122,3.123,3.124,3.125,3.126 defined;
--- 5.2, the addition of "Chapter 21 test can be performed on a single prototype. The first chapters 11, 19 and 21 tests on request in the system
It differs from the cooling system pressure measurements.
The selection Appendix FF (analog leakage test) test is, at least one additional specially prepared prototype.
Chapter 11 when the test, the temperature of the cooling pipe should be measured.
101 Note. Due to Chapter 21, Appendix EE, FF in the appendix of the test itself, there is a potential risk factor in the testing process should take special
Preventive measures. ";
7.1 ---, "maximum working pressure of the heat exchanger" to "water-cooled fan coil/air heat exchanger the maximum processing components
Working Pressure ";
--- 7.1,7.6,7.12 the increased labeling information should be used when a flammable refrigerant;
11.2 ---, the second cross scribing contents changed to "flow of fluid delivery device manufacturers specification shall be specified minimum
Values, flow rate and temperature of the fluid should be a maximum fan coil unless specified in the manufacturer's instructions; ";
--- 15.4 increase "public accessibility of the appliance is installed on an indoor floor or on the wall of the test as follows.";
--- 19.10.1 increase "with respect to the appliance class Ⅰ tubular sheathed or embedded heating element, the test is repeated 19.10.
However, the controller does not short-circuited, and one end of the heating element is connected to its sheath.
Changing the polarity of the power tool, and the other end connected to the heating element to the sheath electric heating element, the test is repeated.
Intended to be permanently connected to the fixed wiring of appliances and utensils all-pole disconnection occurs during the test 19.10, this test is not performed.
Note 1. the appliance with neutral line, were tested in a state connected to the sheath in the midline.
NOTE 2. For embedded heating element, which can be considered as metal housing sheath. ";
