LIGHTING AND HEATING
 F25
REFRIGERATION AND COOLING; MANUFACTURE AND STORAGE OF ICE; LIQUEFACTION AND SOLIDIFICATION OF GASES
 F25B
REFRIGERATION MACHINES, PLANTS, OR SYSTEMS; COMBINED HEATING AND REFRIGERATION SYSTEMS, e.g. HEAT PUMP SYSTEMS (pumps, compressors F04; use of heat pumps for domestic heating F24D; use of refrigeration in air-conditioning F24F)

 F25C
PRODUCTION, WORKING, STORING, OR DISTRIBUTION OF ICE (frozen sweets, including ice-cream, their production A23G 9/00; concentrating solutions by removing frozen solvents B01D 9/04; purification of water by freezing C02B 1/12; refrigeration machines, plants, or systems F25B; solidification of gases or gaseous mixtures F25J; freeze-drying F26B)  [2]
 F25C

Note(s)

In this sub-class, the term "ice" means any frozen liquid and is to be understood as also covering frozen semiliquids or pasty substances [2]


 F25D
REFRIGERATORS; COLD ROOMS; ICE-BOXES; COOLING OR FREEZING APPARATUS NOT COVERED BY ANY OTHER SUB-CLASS (refrigerated show cases A47F 3/04; refrigerated vehicles, see the appropriate sub-classes of classes B60-B64; thermally-insulated vessels for domestic use B65D; thermally-insulated vessels for liquefied or solidified gases F17C; air-conditioning, ventilation F24F; refrigeration machines, plants, or systems F25B; cooling of instruments and comparable apparatus without refrigeration G12B; cooling of engines or pumps, see the relevant classes)
 F25D

Note(s)

In this sub-class, the term "device" refers to an enclosed space to be cooled, such devices being associated either with refrigerating machinery, e.g. as in a refrigerator, or with other cold sources, e.g. as in an ice-box.


 F25J
LIQUEFACTION, SOLIDIFICATION, OR SEPARATION OF GASES OR GASEOUS MIXTURES BY PRESSURE AND COLD TREATMENT (gas storage vessels, gas-holders F17; decantation and vaporisation of liquefied, or solidified gases F17C; refrigeration machines, plants, or systems F25B)
