1. Malinga ndi zotchinga, wotenthetsa amatha kukhala wotenthetsera waya, waya wa pvc, wotenthetsa wa silika, amatha kugawidwa mu mphamvu imodzi ndi magetsi angapo otenthetsa.
2. Kutenthetsa wa PS
3. Amagwiritsidwa ntchito kwambiri m'malo ophatikizika, zowongolera mpweya, ndi zina zowonjezera.
4. Wotenthetsa wa mphira wa Silicone waya wabwino kwambiri, amagwiritsidwa ntchito kwambiri mu firiji, oundana ndi ena. Kuchulukitsa kwakukulu kwamphamvu nthawi zambiri kumakhala pansi pa 40w / m, komanso pansi pa kutentha kochepa ndi kutentha kwabwino, kachulukidwe kamphamvu kumatha kufikira 50w / m, ndipo kutentha kwa kutentha kumakhala -65 ℃ ~.
Wozizira mlengalenga amagwira ntchito kwakanthawi, tsamba lake lidzazizira, pa nthawiyo, waya wotenthetsera wa Antifrizing ukhoza kugwiritsidwa ntchito pochotsa kutulutsa madzi mu firiji kudzera mu firiji kudutsa chitoliro.
Pamene kumapeto kwa chitoliro chomwe chimayikidwa mufiriji, madzi otetezedwa ndi ozizira pansi pa 0 ° C kuti aletse chitoliro chokhacho sichitha kuyika chitoliro cha kukhetsa.
Wa waya wotenthetsedwa umayikidwa mu chitoliro chokwirira ndi kutentha chitoliro nthawi yomweyo kuti madziwo atuluke bwino.
