Amanzi adinga ukushintshwa njalo ukuze kupholiswe umoya opholile ngokusekelwe endaweni yawo yokusebenza. Ngokwesibonelo,
1. Uma indawo yokusebenza iyilabhorethri noma igumbi eline-air conditioning, amanzi angashintshwa njalo ngesigamu sonyaka noma njalo ngonyaka;2.Uma indawo yokusebenza iphansi, njengendawo yokusebenza ngokhuni, kuphakanyiswa ukuthi uguqule amanzi njalo ngenyanga eyodwa noma njalo ngenyanga eyodwa nengxenye.
Ngakho-ke, abasebenzisi bangahlela imvamisa yokushintsha amanzi ngokusekelwe endaweni yokusebenza yomshini wokushisela we-laser ophethwe ngesandla.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.
