Tlhaloso ea Sehlahisoa
Tšebeliso e kholo ea ethylene glycol ke e le ntho e thibelang serame ka har'a pholiso ka mohlala, likoloi le li-air-conditioning systems tse behang li-chiller kapa li-air handlers ka ntle kapa li tlameha ho pholile ka tlas'a mocheso o batang oa metsi. Lits'ebetsong tse futhumatsang / tse pholileng, ethylene glycol ke mokelikeli o tsamaisang mocheso ka ho sebelisa pompo ea mocheso oa mocheso oa mocheso. Ethylene glycol e ka fumana matla ho tsoa mohloling (letšeng, leoatleng, selibeng sa metsi) kapa e ntša mocheso ho teba, ho itšetlehile ka hore na tsamaiso e sebelisetsoa ho futhumatsa kapa ho pholile.
Ethylene glycol e hloekileng e na le matla a khethehileng a mocheso hoo e ka bang halofo ea metsi. Kahoo, ha e ntse e fana ka tšireletso ea leqhoa le ntlha e ntseng e eketseha ea ho bela, ethylene glycol e theola mocheso o khethehileng oa motsoako oa metsi o amanang le metsi a hloekileng. Motsoako oa 1:1 ka boima o na le matla a itseng a mocheso a ka bang 3140 J/(kg·°C) (0.75 BTU/(lb·°F)), kotara tse tharo tsa metsi a hloekileng, kahoo a hloka ho eketseha ha sekhahla sa phallo ka mokhoa o tšoanang- tsamaiso papiso le metsi.
