Momo stikanga pooti 1
Tātaihia te uara pūngoi mai i te pikinga o te pāmahana o tehinuhinu tank
Q = SHxDexVxDT/60
Q: Uara Calorific KW
SH: Ko te wera motuhake o te hinu he 1.97KJ/Kg°C (1.97kJ/kg Celsius)
De: Te taumaha o te hinu 0.88Kg/L
De: Ko te wera motuhake o te wai he 4.2x103J/kg°C
V: te kaha hinu/wai L (rita) tae atu ki te katoa o te kaha wai i roto i te tank hinu me te paipa
DT: Te pikinga teitei o te pāmahana i roto i te meneti kotahi
Tuhipoka: Ka whakamahia te “/60″ ki te huri i te pikinga o te pāmahana i roto i nga nekehanga Celsius/meneti ki nga nekehanga Celsius/tuarua;1kW = 1kJ/s;
Tuhipoka: I te ine, me paku iti iho te pāmahana o te tank wahie i te pāmahana ambient;a kei te mahi nga taputapu i raro i te kawenga teitei.
Tauira: 1 tank rōrahi 3000L mōrahi pāmahana wai hinu ranei 0.6 nekehanga Celsius / min
Uara pūngoi Q= ( 1.97 x 0.88 x 3000 x 0.6) /60 = 52KW
Nga tohutohu taapiri: i te wa e whiriwhiri ana i te kaha whakamahana o te whakamahana hinu, ka taea te whakanui ake ma te 20%-50%.
Momo tikanga whiriwhiri 2
Ko te mana whakawera e kiia ana i runga i te mana motuka o te teihana hydraulic.
Ka whakamahia te hinu Hydraulic hei reo whakawhiti, a ko te ngaronga o te kaha o te punaha ka noho te nuinga ki te ahua o te wera.I runga i te tino wheako o te tïpako, kua whakaräpopotohia e ta mätou kamupene ngä whakarea mate püngao e rite ana o te pünaha waipü i raro i ngä taumahatanga mahi e whai ake nei:
P wera = 1.2x (P nekeneke n)
P motohiko teihana waipēhi hiko katoa: n te whakarea mate pūngao
【Nga korero: 1 Kcal/h=1.163W 1 KW=860Kcal/h】
