| Ho khanna ha mocheso | E phahameng (e betere ho feta R - 410A) | E ntlafatsa bokgoni ba ho phodisa/ho futhumatsa, e fokotsa tshebediso ya matla ya disebediswa |
Likopo tse Tloaelehileng
R-32 e sebelisoa haholo makaleng a fapaneng a indasteri le a bareki ka lebaka la ts'ebetso ea eona e phahameng le melemo ea tikoloho:
Sehatsetsi sa Moea sa Bolulo le sa Khoebo: E le sehatsetsi sa mantlha bakeng sa li-unit tsa AC tsa mofuta o arohaneng, li-AC tsa lifensetere, le litsamaiso tsa VRV (Variable Refrigerant Volume). E nkela R-410A sebaka lisebelisoa tse ncha, e fokotsa tšebeliso ea matla ka 10-15%.
Lipompo tsa Mocheso: Li loketse lipompo tsa mocheso tsa mohloli oa moea (ASHP) le lipompo tsa mocheso tsa mohloli oa metsi (WSHP), tse fanang ka ts'ebetso e tsitsitseng ea ho futhumatsa esita le mochesong o tlase (-10°C ho isa ho 5°C).
Mekhoa ea ho Sehatsetsing: E sebelisoa ka har'a lihatsetsi tse nyane ho isa ho tse mahareng, mabokoseng a lipontšo, le li-unit tsa polokelo e batang, ho netefatsa hore ho pholisa hoa sebetsa hantle ka tšusumetso e fokolang tikolohong.
Lisebelisoa tsa ho Foomisa Foam: Mekhoa e meng ea indasteri, R-32 e sebetsa e le sesebelisoa sa ho foomisa foam e thata ea polyurethane, e ntlafatsang thepa ea ho thibela foam.
Ho kopanya lintho tse phelang: E sebetsa e le thepa e tala tlhahisong ea lik'hemik'hale tse nang le fluorine, ho kenyeletsoa meriana le li-polymer tse khethehileng.
Polokeho le ho Latela Melao
Tataiso ea Polokeho
Ho sebetsana le tsona: Qoba ho kopana ka ho toba le letlalo/mahlo; sebelisa liatlana tse sireletsang, likhalase tsa mahlo le lisebelisoa tsa ho hema libakeng tse se nang moea o kenang hantle.
Polokelo: Boloka sebakeng se pholileng, se omileng, se nang le moea o kenang hantle hole le malakabe a bulehileng, mocheso o phahameng, le lintho tse etsang hore motho a be le oksijene. Sebelisa lijana tse koetsoeng, tse sa senyeheng (mohlala, lisilindara tsa tšepe kapa tsa aluminium).
Lipalangoang: Latela melao ea UN bakeng sa ho tsamaisoa ha lihatsetsi (nomoro ea UN: 3252); etsa bonnete ba hore lisilindara li tiisitsoe hantle ebile li ngolisitsoe ka mabitso.
Ho Latela Melao
E fihlela maemo a ASHRAE 34 (sehlopha sa polokeho sa A2L).
Ho latela Molao wa EU wa F-Gas (Molawana (EU) 2014/512), ho fokotsa mesi e tswang kgase ya F le ho kgothaletsa mekgwa e meng ya ho sebedisa GWP e tlase.
E amohetsoe ke bahlahisi ba lisebelisoa tse kholo (mohlala, Daikin, Mitsubishi Electric, Gree) bakeng sa tšebeliso mefuteng ea bona ea morao-rao ea AC le pompo ea mocheso.

Bohloeki bo Phahameng: Bohloeki bo tsitsitseng ba 99.9% bo netefatsa ts'ebetso e tsitsitseng ea lisebelisoa le bophelo bo bolelele ba ts'ebeletso.
E Sireletsa Tikoloho: GWP e Tlase (675) e tšehetsa lipheo tsa lefats'e tsa ho se nke lehlakore ha khabone 'me e fihlela melao e thata ea tikoloho.
E Bolokang Litšenyehelo: Bokgoni bo phahameng ba mocheso bo fokotsa litšenyehelo tsa eneji bakeng sa basebelisi ba ho qetela, ha bokhoni ba rona ba phepelo e ngata bo fokotsa litšenyehelo tsa theko.
Tšehetso ea Lefatše ka Bophara: Re fana ka lipuisano tsa tekheniki, koetliso ea polokeho, le ho tlisa thepa ka nako ho bareki lefatšeng ka bophara, ka litifikeiti tse kenyeletsang ISO 9001 le REACH.
