I te mea he miihini ngaio kua mahi i roto i te punaha whakamatao, ko te raru tino raru ko te raru whakahoki hinu o te punaha. I te wa e rere ana te punaha, he iti noa te hinu ka waiho tonu i te compressor me te hau pau. I te wa e pai ana te hoahoa o te paipa o te punaha, ka hoki mai te hinu ki te miihini, a ka taea te whakakii i te miihini; Mena he nui rawa te hinu i roto i te punaha, Ka pa kino ki te kaha o te condenser me te evaporator; he iti ake te hinu e hoki mai ana ki te compressor i te waiho i te compressor, i te mutunga ka pakaru te compressor; te whakakii i te kaapiri, ka mau tonu te taumata hinu mo te wa poto; paipa tika anake Ma te hoahoa anake, ka taea e te punaha he toenga hinu pai, katahi ka taea te mahi haumaru o te punaha.
Tuatahi. Te hoahoa o te paipa momi
1. Ko te paipa momi whakapae kia neke ake i te 0.5% te pikinga ki te taha o te rere hau whakapouri;
2. Ko te waahanga whakawhiti o te pipeline momi whakapae me whakarite kia kaua e iti iho te rere o te hau i te 3.6m/s;
3. I roto i te paipa momi poutū, me whakarite te rere o te hau kia kaua e iti iho i te 7.6-12m/s;
4. Ko te rere o te hau nui atu i te 12m / s kaore e taea te whakapai ake i te hokinga mai o te hinu, ka puta te ngangau nui, ka arahi ki te whakaheke teitei i roto i te raina momi;
5. Kei raro o ia raina momi poutū, me whakatu he hokinga hinu ahua U;
6. Mena ka neke ake te teitei o te raina momi poutū i te 5m, me whakarite he hinu whakamuri U-ahua mo ia 5m taapiri;
7. Ko te roa o te piko o te hokinga hinu U-ahua kia poto rawa kia kore ai e nui te kohi hinu;
Tuarua, te hoahoa paipa momi evaporator
1. Ki te kore te punaha e whakamahi i te huringa whakaheke, me whakanoho he mahanga U-ahua ki te putanga o ia whakaetonga. Hei aukati i te rere o te whakamahana wai ki roto i te compressor i raro i te mahi a te kaha i te wa e kati ana;
2. Ina hono te putorino riser momi ki te whakaetonga, me noho he putorino whakapae me te whakapiko haukoti ki waenganui, kia maia ai te whakauru i te pūoko pāmahana; kia kore ai e pakaru te puera roha.
Tuatoru, Hoahoa o te paipa paura
I te wa e whakanohohia ana te condenser ki runga ake i te compressor, ka hiahiatia he U-piko ki te kokoru o te condenser hei aukati i te hokinga mai o te hinu ki te taha tuku o te compressor i te wa e kati ana, me te awhina ano hoki ki te aukati i te rere o te whakamahana wai mai i te condenser. rere hoki ki te compressor.
E wha, hoahoa paipa wai
1. Ko te paipa wai te tikanga karekau he here motuhake mo te tere rere o te whakamahana. I te wa e whakamahia ana he solenoid valve, me iti iho te rere o te rerigerant i te 1.5m/s;
2. Me whakarite ko te whakamahana ka uru ki roto i te puera roha he wai whakamatao;
3. Ka heke iho te pehanga whakamatao wai ki tona pehanga waiwai, ka kohia tetahi wahanga o te pouaka whakamahana ki roto i te hau.
