ʻO ka hoʻohana nui ʻana o ka ethylene glycol ma ke ʻano he antifreeze agent i loko o ka mea hoʻoluʻu ma ka laʻana, nā kaʻa a me nā ʻōnaehana ea e waiho ai i ka chiller a i ʻole nā mea hoʻokele ea ma waho a i ʻole pono e hoʻomaloʻo ma lalo o ke anuanu o ka wai. I loko o nā ʻōnaehana hoʻomehana honua, ʻo ka ethylene glycol ka wai e lawe ana i ka wela ma o ka hoʻohana ʻana i kahi paila wela geothermal. Loaʻa i ka ethylene glycol ka ikehu mai ke kumu (ke loko, ka moana, ka pūnāwai) a i ʻole ka hoʻoheheʻe ʻana i ka wela i ka paila, ma muli o ka hoʻohana ʻia ʻana o ka ʻōnaehana no ka hoʻomehana ʻana a i ʻole ka hoʻoluʻu.
Loaʻa i ka ethylene glycol maʻemaʻe ka mana wela ma kahi o ka hapalua o ka wai. No laila, ʻoiai e hāʻawi ana i ka pale hau a me ka piʻi ʻana o ka paila, e hoʻohaʻahaʻa ka ethylene glycol i ka mana wela o nā hui wai e pili ana i ka wai maʻemaʻe. A 1: 1 hui ma ka nuipaʻa loaʻa kahi wela wela o kahi o 3140 J/(kg·°C) (0.75 BTU/(lb·°F)), ʻekolu hapaha o ka wai maʻemaʻe, no laila e koi ana i ka hoʻonui ʻana i nā kahe kahe i ka like- hoʻohālikelike ʻōnaehana me ka wai.

ʻO ka hui ʻana o ka ethylene glycol me ka wai e hāʻawi i nā pōmaikaʻi hou aʻe i nā mea hoʻonā a me nā antifreeze, e like me ka pale ʻana i ka corrosion a me ka hoʻohaʻahaʻa ʻana i ka waikawa, a me ka pale ʻana i ka ulu ʻana o ka hapa nui o nā microbes a me nā haʻani. glycol concentrates, pūhui, hui pū ʻia, a i ʻole nā hopena.
I loko o ka ʻoihana plastik, he mea nui ka ethylene glycol i nā fiber polyester a me nā resins. ʻO ka polyethylene terephthalate, i hoʻohana ʻia no ka hana ʻana i nā ʻōmole plastik no nā mea inu ʻoluʻolu, ua hoʻomākaukau ʻia mai ka ethylene glycol.

ʻO ka maikaʻi o ka huahana, ka nui kūpono, ka hāʻawi maikaʻi ʻana, ke kūlana kiʻekiʻe o ka lawelawe He ʻoi aku ka maikaʻi ma mua o kahi amine like, ethanolamine, i hiki ke hoʻohana ʻia kahi kiʻekiʻe kiʻekiʻe no ka hiki ʻana o ka corrosion. ʻAe kēia i nā mea hoʻomaʻemaʻe e holoi i ka hydrogen sulfide ma kahi haʻahaʻa haʻahaʻa o ka amine me ka liʻiliʻi o ka hoʻohana ʻana i ka ikehu.
