He mea nui te utu hauhautanga o te pūnaha whakamatao mō te whakahaere o te pūnaha. Ki te kore e ranea te utu, ka kore e ranea te mimiti o te evaporator, ka iti rawa te pēhanga momi o te compressor, ka iti te kaha whakamatao, ā, ka wera rawa te compressor. Mā te nui rawa o te utu ka nui rawa te pēhanga putanga o te condenser, ka hoki mai te hauhautanga wai, ā, ka kino pea te compressor. He maha ngā pūnaha he rohe whaitake mō te nui o te utu, engari he tino kaha ngā whakaritenga a ngā pūnaha iti mō te nui o te utu. E waru ngā tikanga utu hauhautanga e whai ake nei me ō rātou painga me ō rātou ngoikoretanga.
Tikanga 1: Whakakī wai
Ngā taahiraa mahi:
1. Whakatakotoria te pounamu hauhautanga ki runga i te pauna, me te huripokitia ki raro, honoa te paipa whakakī me te takirere whakakī, ka tangohia te hau i roto i te paipa.
2. Whakatuwheratia te takirere o te pounamu hauhautanga me te takirere whakakī, ka whakamahi i te korehau pūnaha hei ngongo i te hauhautanga.
3. Katia te takirere putanga o te kaiwhiwhi wai, tīmatahia te pūwhakakoi, ā, tukua te wai whakamatao kia rere ki roto i te pūnaha.
4. Mātakihia te pēhanga o te pūnaha. Kia tae ki te pēhanga kua tohua, katia te takirere whakakī, ka whakatuwhera i te takirere putanga o te kaiwhiwhi wai.
Tuhipoka:
Ka whakamahia te takirere aukati wai hei whakawhāiti i te hau hei whakahaere i te rere o te hau whakamatao ki roto i te pūnaha.
Me whakaweto te pūnaha ki te pāmahana teitei ina tāutahia mō te wā tuatahi.
Ko te pikinga tere o te pehanga putanga hau e tohu ana kua kī tonu te pūwhakamātao i te wai whakamatao.
Ngā painga me ngā ngoikoretanga:
Ngā Painga: E pā ana ki te nuinga o ngā pūnaha whakamatao.
Ngā Huakore: Me tino mōhio te nui o te whakakī i te hauhautanga, ā, ko te nui o te whakakī e whakaratohia ana e te kaihanga te mea e hiahiatia ana.
Tikanga 2: Te whakakī hau
Ngā taahiraa mahi:
1. Paunatia te taumaha o te pounamu hauhautanga.
2. Honoa te paipa takirere ine pēhanga ki ngā takirere tirotiro momi me te putanga hau hei tango i te hau i roto i te paipa.
3. Whakatuwheratia te takirere mamaoa o te pounamu whakamatao, tīmatahia te pūwhakakoi, ka whakatikahia te nui o te whakakī mā te ine pēhanga.
Tuhipoka:
I muri i te whakakī, katia te takirere o te pounamu whakamatao, tirohia te mahi a te pūnaha, kātahi ka whakatau mēnā ka haere tonu te whakakī.
Ngā Painga me ngā Huakore:
Ngā Painga: He pai mō ngā pūnaha iti he tino tika te whakakī.
Ngā Huakore: He pai anake mō te whakakī i te hauhautanga i roto i te iti noa iho (kāore e neke atu i te 12kg te taumaha).
Tikanga 3: Tikanga pauna
Ngā taahiraa mahi:
Paunatia te taumaha o te matū whakamatao kua tāpirihia ki te pūnaha.
Tuhipoka:
E pā ana ki te āhuatanga e mōhiotia ana te nui o te utu e hiahiatia ana mō te pūnaha, ā, me utu katoa.
Mēnā he iti te nui o te utu, me tuku tuatahi te hauhautanga i roto i te pūnaha, kātahi ka utua anō i muri i te whakatikatika.
Ngā painga me ngā ngoikoretanga:
Ngā Painga: He pai mō ngā taputapu whakauru, he māmā hoki te whakahaere.
Ngā Huakore: Me mōhio wawe ki te nui o te utu mō te pūnaha.
Tikanga 4: Tikanga o nāianei
Ngā taahiraa mahi:
1. Tāutahia he mita āmipere ki te pito tāuru hiko o te hauhautanga.
2. Honoa te pounamu hauhautanga ki te putanga whakakī wai pēhanga-iti hei tango i te hau i roto i te paipa.
3. Tīmatahia te pūwero, whakatuwheratia te takirere o te pounamu hauhautanga, tirohia te āmita, kātahi ka mutu te utu ina tae te iahiko ki te uara kua whakatauria.
Tuhipoka:
He maha ngā mea e pāngia ana e te iahiko, pērā i te piki me te heke o te ngaohiko, te pāmahana o te taiao, me ētahi atu.
Ngā painga me ngā ngoikoretanga:
Ngā Painga: Ngāwari ki te whakahaere.
Ngā Huakore: Ka ngāwari te whakakorikori i te iahiko e ngā āhuatanga o waho, ā, he iti te tika.
Tikanga 5: Tikanga whakaata
Ngā taahiraa mahi:
Mātakihia te rere o te hauhautanga mā roto i te karāhe tirohanga i roto i te paipa wai. Ko te rere o te hauhautanga wai mārama e tohu ana kua tika te utu.
Tuhipoka:
Ko te āhua o ngā mirumiru, o ngā uira rānei, he tohu tēnei kāore i te rawaka te hauhautanga.
Tērā pea ka puta he mirumiru i te ngaronga o te pēhanga o ngā paipa wai, me hono atu tēnei ki te tātaritanga mahi a te pūnaha.
Ngā painga me ngā ngoikoretanga:
Ngā Painga: mārama, ā, he ngāwari ki te mātakitaki.
Ngā Huakore: kāore e taea te whakawhirinaki katoa ki te karāhe tirohanga hei whakatau, ā, me whakakotahi ētahi atu tikanga.
Tikanga 6: Tikanga pēhanga
Ngā taahiraa mahi:
1. Tāutahia ngā ine pēhanga ki ngā wāhanga pēhanga teitei me te pēhanga iti, ka hono i te paipa whakakī wai.
2. Tīmatahia te pūwero, tirohia ngā tohu o ngā ine pēhanga teitei me te iti, ka aromatawai i te nui o te utu.
Tuhipoka:
Ka pāngia ngā hua o te whakamātautau pehanga e te kore e ranea te rahinga o te hau whakamātao me te rahinga o te hau mimiti.
I mua i te whakamātautau, me whakarite kia tutuki i te rahinga hau pūnaha ngā whakaritenga.
Ngā painga me ngā ngoikoretanga:
Ngā Painga: he tika ake mā te whakatau pēhanga.
Ngā Huakore: he nui te pānga o ngā āhuatanga o waho, he mea tika kia whakarite kia mahi noa te pūnaha.
Tikanga 7: Tātaitanga o te tikanga wera nui
Ngā taahiraa mahi:
Tātaihia te wera nui mā te ine i te pāmahana me te pēhanga momi o te paipa momi whakapūhau.
Tuhipoka:
Ka pāngia te wera nui o te pūnaha capillary e te pēhanga me te ātete.
He ngāwari te pūnaha takirere whānui ki te whakakī rawa, ā, me whakahaere te wera nui ki te 58℃.
Ngā painga me ngā ngoikoretanga:
