Isi ojiji nke ethylene glycol bụ ihe na-egbochi friza na coolant dị ka ihe atụ, ụgbọ ala na ikuku oyi na-etinye na chiller ma ọ bụ ikuku njikwa n'èzí ma ọ bụ ga-ajụkwa n'okpuru kefriza okpomọkụ nke mmiri. N'ime usoro ikpo ọkụ / ikpo ọkụ geothermal, ethylene glycol bụ mmiri na-ebufe okpomọkụ site na iji mgbapụta ọkụ geothermal. Ethylene glycol na-enweta ike site na isi iyi (ọdọ mmiri, oke osimiri, mmiri mmiri) ma ọ bụ na-ekpochapụ okpomọkụ na sink, dabere ma a na-eji usoro ahụ eme ihe maka ikpo ọkụ ma ọ bụ dị jụụ.
Ethylene glycol dị ọcha nwere ikike ikpo ọkụ dị ihe dị ka ọkara nke mmiri.
