He mea tino nui te whiriwhiri i tētahi pūwero CO2 kounga teitei. Ina whiriwhiria e koe te pūwero tika, ka taea e koe te whakamahi hei whakaputa i te hua pai rawa atu mō ngā hua teitei ake.
Ngā mea nui:
Te kaupapa o te pūhiko CO2
Ngā āhuatanga pai o ngā pūwero CO2
He tono tino pai mō ngā pūwero CO2
Te kaupapa o te pūhiko CO2
Mai i te umanga tono o ngā pūwero, ko ngā umanga e whakamahia ana mō te hau kōpeke ko ngā mīhini, ngā motuka, ngā hikohiko, te hikohiko, te whakarewa, te keri, te hanga, ngā rauemi hanga, te hinu, te matū, te hinu-matū, te kakahu, te tiaki taiao, te ope taua me ētahi atu mara ahumahi me ngā mara ā-iwi. Ngā mara katoa o te whakaputa me te oranga. He puna nui te hau kōpeke mō ngā hua ahumahi, ā, e mōhiotia ana hoki ko te "puna ora" mō te whakaputa hua ahumahi.
He maha ngā momo pūwero hau, ka taea te wehewehe ki ngā wāhanga e toru i runga i te āhua o tā rātou mahi: te rōrahi, te hihiri (tere, turbo rānei) me te wera. I roto i ngā pūwero nekehanga pai, ka tutuki te pikinga o te pēhanga mā te whakawhirinaki ki te pēhanga tika o te rōrahi hau. I roto i te pūwero hiko, ka huri te impeller i te tere teitei hei whakanui ake i te pēhanga me te tere o te hau, ā, i roto i te huānga tūmau, ka taea te huri i tētahi wāhanga o te tere hei pūngao mō te pēhanga o te hau. He pūreretā wera te jet. Ka whakamahia e ia he jet hau tere-teitei, he jet mamaoa rānei hei kawe i te hau e rere ana ki roto, ka hurihia hei pūngao pēhanga i te tere o te ranunga kua horapa.
Ngā āhuatanga pai o ngā pūwero CO2
Ki te whakatauritea ki ngā pūwero hauhautanga noa, he nui te pēhanga mahi a ngā pūwero hauhautanga CO2, he nui te rerekētanga o te pēhanga, he iti te ōwehenga pēhanga, he iti te rahinga, he māmā te taumaha, he uaua ki te whakahaere i te ātea o ngā wāhanga neke, ā, he uaua hoki ngā āhuatanga whakahinuhinu. Nō reira, he uaua tonu te rangahau me te whakawhanake i ngā pūwero hauhautanga waro i roto i te whanaketanga o te hangarau whakamatao. He maha ngā whare rangahau me ngā kamupene taputapu whakamatao kua whakawhanake i ngā momo pūwero hauhautanga i te kāinga me tāwāhi. Nā te mea he pai te taiao o te CO2 i roto i ngā tono hauhautanga motuka, kua akohia, kua whakawhanakehia hoki ngā pūwero hauhautanga CO2 motuka mā roto i ngā kamupene whakamatao me ngā kamupene waka.
He tono tino pai mō ngā pūwero CO2
1. I roto i te whakamahinga o te hauhautanga motuka, i tēnei wā, kei raro i ngā āhuatanga whakawhiti-arotake te pūnaha hauhautanga, ā, he teitei te pēhanga mahi engari he iti te ōwehenga kōpeketanga, he teitei te whai huatanga o te compressor; nā te pai o te whakawhiti wera me ngā āhuatanga thermodynamic o te wai supercritical ka tino teitei te whai huatanga o te whakawhiti wera, ka nui ake te whai huatanga o te pūnaha hauhautanga, ā, ka taea te whakataetae ki ngā refrigerants tuku iho (pēnei i te R12, R22, me ētahi atu) me ētahi atu momo kē atu (R134a, R410A, me ētahi atu). Mō te whanaketanga o ngā waka hiko, ka taea hoki e ngā āhuatanga o ngā papu wera waro hauhā te whakaoti i te raruraru kāore e taea e ngā hauhautanga motuka hou te whakarato i te wera nui ki te motuka i te takurua. Nā roto i ngā rangahau whakamātautau maha, kua whakaatuhia ko te huringa whakawhiti-arotake o te CO2 mō te hauhautanga waka ehara i te mea he painga taiao anake, engari he whai huatanga pūnaha anō hoki.
2. Whakamahia ki ngā momo papu wera, inā koa ngā whakamahana wai papu wera. I tēnei wā, kei te mahi anō te pūnaha papu wera i raro i ngā āhuatanga whakawhiti-arotake, ā, kei te mau tonu ngā painga o te pūwhakakoi me te whakawhiti wera; ko te panonitanga nui o te whakamahana hau CO2 he pai mō te whakamahana i te wai, nā reira ka pai ake te mahi a te papu wera, ā, ka taea te whakataetae ki ngā hauhautanga tuku iho (R134a, R410A, me ētahi atu). Mā te ako i te papu wera CO2, ehara i te mea ka taea te whakaiti i te tukunga CO2 anake, engari he pai te mahi a te papu wera, ā, he whānui te tono me te whanaketanga.
3. Te whakamahinga i roto i te pūnaha whakamatao cascade. I tēnei wā, ka whakamahia te CO2 hei pouaka whakamātao pāmahana iti, ā, ko te pāmahana teitei ka hangaia ki te NH3, ki te R290 rānei hei pouaka whakamātao. Ki te whakatauritea ki ētahi atu pouaka whakamātao cryogenic, ahakoa i ngā pāmahana iti, he tino iti te matotoru o te CO2, he pai te mahi whakawhiti wera, ā, he nui te kaha tio.
I tēnei wā, kua whānuitia te whakamahinga o te pūnaha whakamatao NH/CO2, me te NH3 hei hauhautanga, me te CO2 hei pūnaha whakamatao wai i roto i te hangarau kawe waka, te tukatuka heihei, te hanga hukapapa, ngā kai whakangawari me ngā hua wai i Haina.
