He kaimahi a Mr. Francois mā tētahi kamupene Wīwī e tohunga ana ki te hanga ngongo reihi CO2 whakauru mana teitei, ā, he 150W te kaha o ia ngongo. Kei te ngana tana kamupene inaianei ki te whakapiko i ngā ngongo reihi e 3, i ngā ngongo reihi e 6 rānei, engari kei te wāhanga R&D tonu. E mōhio ana tātou katoa, he mea nui te mahi a ngā pouaka whakamatao ahumahi ki te whakamatao i ngā ngongo reihi CO2 kia mahi noa ai, kia kore ai hoki e pakaru nā te pāmahana teitei.
Kua whakamahia e Mr. Francois te mīhini whakamatao wai S&A Teyu CW-6200 hei whakamatao i ngā ngongo taiaho CO2 e toru, ā, he tino pai te mahi whakamatao. Engari i ēnei rā, i kitea e ia kāore i te tino pai te pānga whakamatao o te mīhini whakamatao i te raumati. E ai ki ngā wheako o S&A Teyu, tera pea ka pāngia te mīhini whakamatao e tēnei raruraru i muri i te whakamahinga roa, ko te nuinga nā ēnei take e whai ake nei:
1. He tino paru te whakawhiti wera i roto i te pouaka whakamatao. Tēnā horoia te whakawhiti wera kia tika.
2. Ka turuturu te Freon mai i te pūnaha whakamatao. Tena koa kimihia, whakarewahia te pūwāhi turuturu, kātahi ka whakakī anō i te hauhautanga.
3. Kei te rere te pouaka whakamatao i roto i tētahi taiao kino rawa (arā, he tino tiketike rawa, he tino iti rawa rānei te pāmahana o te taiao), ā, kāore e taea e te pouaka whakamatao te whakatutuki i ngā whakaritenga whakamatao o ngā taputapu. Mēnā koinei te āhua, whiriwhiria tētahi atu pouaka whakamatao e tika ana.
I whakaaetia e Mr. Francois te whakaaro, ā, i whakatauhia te raruraru mā te horoi i te whakawhiti wera i te mutunga.
Mō te hanga, kua whakangaohia e S&A Teyu te neke atu i te kotahi miriona yuan mō ngā taputapu hanga, hei whakarite i te kounga o te raupapa o ngā tukanga mai i ngā wāhanga matua (whakamātao) o te pouaka whakamatao ahumahi ki te whakarewa i te pepa whakarewa; mō te mahi kawe taonga, kua whakatūria e S&A Teyu ngā whare putunga kawe taonga i roto i ngā tāone nui o Haina, ā, kua tino whakaitihia te kino nā te kawe taonga tawhiti, me te whakapai ake i te whai huatanga o te kawe waka; mō te ratonga muri-hoko, e rua tau te wā whakamana.
