g/unit total
Fridges/freezers 240 111 351
Fridges 240 65 305

Table 2. Imports and exports of HFC-134a calculated as net exports of fridges and freezers (source: Statistics Denmark's foreign trade statistics)

Exports, units 1998 1997 1996 1995 1994 1993 1992
Fridges/freezers 26,387 65,491 40,040 48,332 47,851 72,017 66,488
Fridges -109,550 4,308 -30,381 -90,011 -29,184 -11,382 -7,250
Chest freezers 815,523 778,580 701,748 879,172 855,691 771,198 766,453
Freezers 89,878 135,376 56,385 72,232 68,278 80,312 92,278
Exports, total units 822,238 983,755 767,792 909,725 942,636 912,145 917,969
Exports of foam (a16 chest freezers) 6,715 205,175 66,044 30,553 86,945 140,947 151,516
Total exports of HFC-134a, tonnes 338.3 388.5 309.0 371.2 372.4 90.7 0.0
HFC-134a (foam) 197.3 236.1 184.3 218.3 169.7 54.7  
HFC-134a (fridges) 141.0 152.4 124.7 152.9 202.7 36.0  
HFC-134a (foam, exports) 1.6 49.2 15.9 7.3 20.9 33.8 36.4

It should be noted that this is an over-simplification since the quantity of HFC used for foam and refrigerant varies depending on the producer and product size. The average quantities used in the evaluation are shown in Table 2.

Table 3. Statistical data on imports and exports of cars and lorries

Airconditioning Cars Lorries Total, tonnes
Net imports, 1998 151,385 26,249  
Proportion with A/C 151,38.5 13,124.5  
Amount of HFC 134a, kg 11,353.875 16,405.625 27.8

Car: 10% with A/C and 0.75 kg - 134a
Lorry: 50% with A/C and 1.25 kg - 134a
