Wok bilong bosim temperaja bilong ol ea kondisen na ol 'chiller' i save kamap long rot bilong 'evaporation' na 'condensation' bilong ol kopa 'tube' insait long 'heat exchanger'. Sais na pefomens bilong ol 'heat exchange heat transfer tubes' i save makim gutpela na liklik bilong olgeta 'air conditioning unit' na ol samting bilong mekim kol. Olgeta spesel-seip kopa paip we i gat bikpela 'thermal conductivity' ol i yusim long ol dispela masin. Long kisim sans long gutpela wok bilong ain, i no long taim i go pinis, ol i kamapim na wokim ol 'heat dissipation tubes' wantaim ol 'inner grooves' na 'high fins'. Ol i save yusim long wokim ol 'heat exchanger' insait long ol ea kondisen, aisbokis, ol kemikel na ol pipia hat koleksen divais, na ol narapela samting. Dispela inap long apim 'total thermal conductivity' bilong nupela kain 'heat exchanger' i go antap long 2 o 3 taims bilong ol nomol 'tube' na 1.2 i go 1.3 taims bilong ol 'ordinary low-finned' 'tubes'. Ol i bin putim ol long yusim long Saina. Em inap long sevim 40% bilong kopa na daunim volium bilong 'heat exchanger' long moa long wanpela hap bilong tripela hap.
