Isiqandisi siyindlela yokusebenza yokujikeleza kwesiqandisi ku-compressor air cooled water chiller. Isiqandisi simunca ukushisa ngesikhathi sokuhwamuka ku-evaporator bese sikhulula ukushisa ngesikhathi sokujiya kusikhonde. Lezi zinqubo ezimbili ziya emuva naphambili zenza i-chiller ibe yifriji. Kunezinhlobo ezimbili zeziqandisi ezisetshenziswa ezimbonini -- isiqandisi esivumelana nemvelo esihlanganisa i-R134A, i-R410A ne-R407C kanye nesiqandisi esingavumelani nemvelo okuhlanganisa no-R22.
Ekuhwebeni kwamazwe ngamazwe, amanye amazwe angase adinge i-compressor air cooled water chiller ilethwe nesiqandisi esivumelana nemvelo ngenjongo yokuvikela imvelo. S&A I-Teyu compressor air cooled chillers yamanzi, wonke akhokhiswa iziqandisi ezivumela imvelo.
Mayelana nokukhiqizwa, i- S&A I-Teyu itshale izimali zokukhiqiza ezingaphezu kwesigidi samayuan, iqinisekisa ikhwalithi yochungechunge lwezinqubo kusukela ezingxenyeni eziyinhloko (i-condenser) ye-chiller yezimboni kuya ekushiseleni kweshidi lensimbi; ngokuphathelene nempahla, S&A I-Teyu imise izindawo zokugcina izimpahla emadolobheni amakhulu aseShayina, inciphise kakhulu umonakalo ngenxa yokuhanjiswa kwezimpahla ezikude, kanye nokusebenza kahle kwezokuthutha; mayelana nesevisi yangemuva kokuthengisa, isikhathi sewaranti iminyaka emibili.
