● Ka whakamahia e te miihini nga miihini kawemai me nga papu wai, he haumaru, he ata noho, he whakaora hiko, he roa.
● Ka whakamahia e te miihini te tino rorohiko rorohiko, me te mahi ngawari me te whakahaere tika o te pāmahana wai i roto i te ± 3 ℃ ki te ± 5 ℃.
● Ko te condenser me te evaporator he mea hanga motuhake mo te pai ake o te whakawhiti wera.
● Kei te miihini nga ahuatanga whakamarumaru penei i te whakamarumaru o te tere, te mana ngaohiko teitei me te iti, me te taputapu haumaru wa-roa hiko. Mena he kino te mahi, ka tukuna e ia he whakaoho me te whakaatu i te take o te rahunga.
● Kei roto i te miihini he kowiri tira i hangaia he tank wai, he ngawari ki te horoi.
● Ko te miihini he waahi whakamuri me te whakamarumaru i raro i te ngaohiko, tae atu ki te whakamarumaru whakatio.
● Ka taea e te miihini wai makariri te momo pāmahana ultra-iti ki raro -15 ℃.
● Ko tenei raupapa o nga miihini wai makariri ka taea te whakarite kia kaha ki te waikawa me te alkali.
