For heat transfer fluids that are not gaseous under atmospheric pressure, the requirements for the heat transfer fluid circuit do not belong to the scope of this part, but this part still applies to any safety devices related to the refrigeration system. This part does not apply to refrigeration systems using air or water as refrigerants, nor does it include requirements for refrigeration equipment used in potentially explosive atmospheres. The auxiliary equipment of the refrigeration system includes. - Fan and fan motor; - Motor and transmission mechanism of open compressor. This part specifies the requirements related to fixed and mobile refrigeration systems (including heat pumps) of various sizes. This part is not applicable to systems using refrigerants not listed in Appendix D of Part One of this standard, as long as the safety groups of these refrigerants have not been determined. The basic safety requirements for refrigeration systems in Part 1 of this standard are also applicable in this part. Part 3 of this standard also applies to the basic requirements of the installation site.
