3.1 Apliances NOTES 1 From the point of view of installation, there are various types of household refrigerator-freezers and their combi nations: free-standing, built-in, etC. 2 Definitions 3.1.1 and 3.2.2 are in line with those for a “three star” compartment and food freezer compartment given in ISO 8187. 3.1.1 household frozen food storage cabinet (hereinafter referred to as “three star” cabinet): Insu- lated cabinet of suitable volume and equipment fo household use, cooled by energy-consuming means and having one or more compartments. The storage temperature of the compartments, measured as de- scribed in clause 13, is not warmer than – 18 °C. 3.1.2 household food freezer (hereinafter referred to as freezer): Insulated cabinet of suitable volume and equipment for household use, cooled by energy- consuming means and having one or more compart- ments for freezing fresh food. The freezer is suitable for freezing, from + 25。C to- 18。C for class SN, N andSTappliances,andfrom+32°Cto-18。Cfor class T appliances (see clause 4), a quantity of at least 4,5kg of test packages per 100 | of its storage vol- ume in 24 h, and in no case less than 2 kg, under the test conditions specified in clause 17, and is also suitable for the storage of frozen food under storage conditions (see 3.1.1).
3.5.1 refrigerant: Fluid used for heat transfer in a refrigerating system, which absorbs heat at a low temperature and a low pressure of the fluid and re- jects heat at a higher temperature and a higher pressure of the fluid, usually involving changes of state of the fluid. 3.5.2 cooling device: Device containing the evaporator or in thermal contact with the evaporator; it may be a device with fins or may be suitably shaped for the storage of frozen food or water ice cubes. 3.6 Definitions relating to compression-type “three star” cabinets or freezers 3.6.1 compression-type “three star”cabinet or freezer: “Three star” cabinet or freezer in which re- frigeration is effected by the vaporization at low pressure in a heat exchanger (evaporator) of a liquid refrigerant, the vapour thus formed being restored to the liquid state by mechanical compression to a higher pressure and subsequent cooling in another heat exchanger (condenser). 3.6.2 hermetically sealed motor-driven refriger- ating compressor: Motor-compressor in which the compressor and the electric motor (or its moving parts at least) are enclosed in a shell rendered gastight by welding, brazing or other means such that dismantling is not normally possible after assembly. It does not include moving parts outside the shell. .
