This document is equivalent to IEC 60335-2-104.2021 "Safety of Household and Similar Electrical Appliances Part 2-104.Air Conditioners and

Particular requirements for appliances for recovering and/or regenerating refrigerants in refrigeration equipment.

The following minimal editorial changes were made to this document.

--The name of the standard was changed to "Safety of Household and Similar Electrical Appliances Part 92.Recovery and/or Recycling of Waste from Air Conditioning and Refrigeration Equipment"

Particular requirements for appliances using refrigerants to enhance the coordination of the standard system.

Introduction

GB/T 4706 "Safety of Household and Similar Electrical Appliances" mostly adopts IEC 60335.On this basis, GB/T 4706 refers to

The structure of IEC 60335 is divided into several parts, consisting of general requirements and special requirements. Part 1 is general requirements, and the other parts are

For products covered by special requirements, their safety requirements are general requirements used in combination with the special requirements.

The requirements include supplements and modifications to the corresponding clauses in the general requirements to provide complete requirements for each product.

This document is the protection that the equipment needs to have against electrical, mechanical, thermal, fire and radiation risks when it is used normally according to the instructions.

This document also covers abnormal conditions that may occur during use and considers how electromagnetic interference may affect the safe operation of the appliance.

This document has taken into account the requirements specified in GB/T 16895 "Low Voltage Electrical Installations". The appliance is connected to the power supply in accordance with the electrical wiring rules.

requirements are coordinated.

If multiple functions of an appliance involve other parts of GB/T 4706, the other parts shall apply to the appliance separately as long as it is reasonable.

Each function. If applicable, consider the impact of one function on other functions.

When no additional requirements are given in other parts for hazards already included in this document, GB/T 4706.1 applies.

GB/T 4706 is a standard covering appliance safety and takes precedence over general standards/horizontal standards covering the same subject.

This document is used in conjunction with GB/T 4706.1-2024 "Safety of Household and Similar Electrical Appliances Part 1.General Requirements".

The part marked "applicable" in the document indicates that the corresponding clauses in GB/T 4706.1-2024 are applicable to this document; the part marked "replaces" in this document indicates that the corresponding clauses in GB/T 4706.1-2024 are applicable to this document.

For the parts marked as "added" in this document, in addition to complying with the provisions in GB/T 4706.1-2024,

In addition to the corresponding clauses, the clauses added in the clauses of this document must also be complied with; the part of this document marked "modified" means that in GB/T 4706.1-

The relevant provisions of 2024 shall be amended.

Safety of household and similar electrical appliances Part 92.

Recovered and/or regenerated from air conditioning and refrigeration equipment

Particular requirements for appliances using refrigerants

1 Scope

This chapter of GB/T 4706.1-2024 is replaced by the following.

This document specifies the safety requirements for appliances for recovering and/or regenerating refrigerant from air conditioning and refrigeration equipment.

The appliances specified in this document are suitable for use in air conditioners, heat pumps and refrigeration equipment equipped with open compressors or motor-compressors.

The maximum rated voltage of electrical appliances shall not exceed 300 V and the rated voltage of other appliances shall not exceed 600 V.

This document also applies to appliances which are not intended for normal household use but which may nevertheless present a danger to the public, e.g.

Tools used by professionals in industry and on farms.

The above appliances may consist of one or more factory-produced components. If multiple components are supplied, and the individual components

are intended to be used together, then the technical requirements of this document shall be based on use of the components assembled together.

NOTE 101.For the purposes of this document, "appliance" refers to equipment for recovering and/or regenerating refrigerant.
