Mita BTU He taputapu e whakamahia ana hei ine i te whakamahinga wera (pūngao), ko te aro turuki i te wera e tukuna ana e ngā wai (pēnei i te wai, ngā otinga ethylene glycol, me ētahi atu) i te wā e rere ana. He mea whakamahi noa i roto i ngā āhuatanga pēnei i te HVAC (Whakamahana, Whakahauora, me te Āhuarangi), te whakahaere pūngao ahumahi, me ngā pūnaha whakamatao.
Mahi Matua:
Mā te ine i te tere rere o te wai me te rerekētanga pāmahana i waenga i te tomokanga me te putanga, ka tatauhia te uara wera mā te whakamahi i ngā tātai thermodynamic. Ko te waeine ko te British Thermal Unit (BTU) me ōna waeine taupatupatu (pēnei i te MBTU, miriona BTU).
Ko te tātai tatau ko:
Q=Rere Rere×Te Pūmanawa Wera Motuhake o te Wai×(Mahana Tomokanga−Mahana Putanga)
(kei te BTU te wera, Q).
Te Whakarōpūtanga me ngā Mātāpono:
Mā te Mātāpono Ine:
Momo Mīhini: Ka whakaoho i te rere mā roto i ngā wāhanga mīhini pēnei i ngā impeller, ā, ka tatau i te wera mā roto i ngā ine pāmahana (he rite ki ngā mita wai tuku iho).
Momo Ultrasonic: Ka ine i te rere mā te whakamahi i te tikanga wā-o-te-rere ultrasonic, e tuku ana i te tika teitei ake, ā, kāore he pakaru ā-mīhini (hei tauira, ngā mita wera ultrasonic ā-roto).
Momo Aukume Hiko: Ka ine i te rere i runga i te aukume hiko, e tika ana mō ngā wai kawe hiko.
Mā te Tikanga Tāutanga:
Momo Whakaurunga (Rārangi): Ka tāuta tika ki roto i ngā paipa, he pai mō ngā āhuatanga ahumahi matua.
Momo Whakapiripiri: Ka tāpirihia ki te taha o waho o ngā paipa, kāore he wero, he watea mō te tāutanga engari ka pāngia te tika e ngā āhuatanga o te paipa.
Ngā horopaki tono:
Whakahaere Pūngao Whare: Te aroturuki i te whakapaunga wera i roto i ngā pūnaha hauhautanga pokapū, ngā kohua, ngā pūnaha waiariki rānei hei tātari utu, hei tātari whai huatanga rānei.
Ngā Tukanga Ahumahi: Te ine i te wera i roto i ngā pūnaha whakamatao/whakamahana puta noa i ngā ahumahi pēnei i te miihini matū me te tukatuka kai.
Ngā Pūnaha Whakamatao: Te aroturuki i te whai huatanga o te pūngao mō ngā waeine rokiroki makariri me te pouaka whakamātao.
Ngā Painga:
Te Ine i te Whakamahinga Pūngao: Ka āwhina i ngā kaiwhakamahi ki te mārama ki te whakamahinga wera me te arotau i te tohatoha pūngao.
Teitei o te Tika: Ka taea e ngā momo ultrasonic te whakatutuki i ngā hapa tae noa ki te ±0.5%, e tutuki ai ngā whakaritenga whakataunga hokohoko.
Matauranga: Tautoko i te tuku raraunga mamao, te rokiroki tuhinga hītori, me te urutau ki ngā Pūnaha Whakahaere Pūngao (EMS).
