Hka lum ai shara law law kaw na langai hku nna, hka lum ai shara ni hpe galai shai ai ni gaw kaga nbung hpe galai shai ai ladat ni hte shingdaw yang, akyu nkau mi nga ai.Ndai akyu ni a majaw, dai gaw gat lawk hpe lawan ladan zing madu la lu nna, lang ai masha law law a masat masa hpe lu la sai. Raitim, hka{2}} kaw na hka n-gun galai ai jak rai tim, kaga nbung katsi ai ni hpe galai shai ai ladat ni rai tim, operation galaw ai aten hta ngang grin ai bungli galaw ai masa hpe makawp maga na matu, lam law law hpe myit maju jung ra ai. Dai majaw, hka- hpe hka a n-gun n rawng ai hku galaw ai hpe dawdan ya ai lam ni gaw hpa ni rai kun?
Nbung galai shai ai shara: Heat galai shai ai shara gaw, nbung laru galai shai ai atsam hpe dawdan ya ai madung lam re.Katsi galai shai ai shara gaw, nbung laru galai shai ai shara ni hpe grau law hkra jaw ya lu ai, katsi ai hte katsi ai hka ni hpe langai hte langai matut mahkai lu shangun ai, dai hku nna katsi ai galai shai ai atsam hpe grau kaja hkra galaw ya lu ai.Hka makau na hka wan galai shai ai hpung hta, plate ni a plate jahpan hte plate heat exchanger a structural design gaw, nbung laru galai shai ai shara a galu kaba ai lam hpe dawdan ya ai, dai majaw, nbung laru galai shai ai lam hpe grau kaja hkra galaw na matu, manu dan ai plate layout gaw ahkyak dik rai nga ai.
Heat htawt sit ai arung arai: Hka lum ai lam hpe htawt sit ai arung arai a thermal conductivity gaw nbung katsi ai lam hpe grai hkra machyi shangun ai. thermal conductivity grai law ai arung arai ni, copper hte aluminum alloy zawn re ai ni gaw, katsi ai shara de htawt sit ai lam hpe lawan ladan galaw ya lu nna, htawt sit ai aten hta katsi ai hpe shayawm ya lu ai.
2.Operating masa ni
Fluid flow hte velocity: Hka lum ai hte katsi ai ntsin ni a lwi ai hte n-gun n-gun hpe hkang lu ai gaw, katsi ai hpe htawt sit lu ai atsam hta ahkyak ai hkra machyi lam nga ai.Hka lim ai lam hpe atsawm sha jat ya lu ai gaw, hka lim ai lam hpe jat ya lu ai, lamu ga jarit layer thermal resistance hpe shayawm ya lu ai, katsi ai hpe lawan ai hku htawt sit ya lu ai.Raitim, grai law ai hka lwi ai lam gaw n-gun jai lang ai lam law wa nna, jak rung ni hpe mung jat wa shangun chye ai, dai majaw, rap ra ai lam hpe mu lu na matu ra kadawn nga ai.
Hkringhtawng hte n-gun hpe hkang ai lam: Operator a nbung laru hte n-gun hpe hkrak hkrak gram lajang lu ai atsam gaw, nbung laru galai shai ai jak a bungli galaw ai atsam hpe hkra machyi shangun ai madung lam langai mung rai nga ai.Hka lum ai hte katsi ai ntsin ni a shang wa ai hte pru wa ai nbung katsi ai lam ni hpe gram lajang ai hku nna, nbung galai shai ai nta a shingra tara bungli galaw ai lam hpe hkam la lu na re.
Hka a hkam kaja lam: Hka a hkamja lam gaw nbung laru galai shai ai lam hpe hkrak hkra machyi shangun ai.Hka hta n san seng ai lam law law lawm ai rai yang, nhprang wan n-gun gaw nbung galai shai ai shara ntsa hta byin wa na re, nbung hpe ninghkap lu ai atsam hpe jat ya lu ai hte nbung galai shai ai atsam hpe shayawm ya lu na re.
Ambient temperature hte hka lim ai lam: Ambient temperature hte hka lim ai lam mung nbung laru galai shai ai jak hpe teng sha hkra machyi shangun ai. Nbung laru kaba hte nbung laru kaba ai shara ni hta, dai jak ni a nbung laru hpe pat shingdang lu ai majaw, shi a bungli galaw ai atsam hpe hkra machyi shangun ai.
4.Jinghpan lam hte hparan hpareng ai lam
Aten tup gram lajang ai lam: Ndai hta heat exchanger hpe jasan jaseng ai, hka lim ai hpe jep yu ai, hkra machyi ai daw ni hpe galai shai ai lam ni lawm nna, n-gun rawng ai bungli ni hpe galaw lu na matu hte ngang grin ai bungli galaw lu na matu. Aten tup gram lajang ai gaw, jak a asak hpe galu shangun nna, n-gun hte n-gun yawm ai majaw hkrat sum ai lam ni hpe shayawm ya lu ai.
Vibration hpe hkang zing ai lam: Hka- kaw na hka n-gun n-gun hpe n-gun jaw ai- kaw na hka n-gun galai ai jak ni gaw shanhte a kata na hka n-gun kaba ai majaw n-gun n-gun jat wa chye ai. Ndai vibration gaw arung arai ni a bungli galaw ai lam hpe hkra machyi shangun ai sha n-ga, gram lajang ai manu hpe mung jat ya ai. Dai majaw, spring dampers ni hpe jung ai zawn re ai, htap htuk ai vibration hpe hkang zing ai ladat ni gaw, ngang grin ai unit hpe galaw lu na matu ahkyak nga ai.
Tsun ga nga yang, hka{0}} de hka n-gun hpe ngang grin ai hku galaw ai lam hpe dawdan ya ai madung lam ni gaw, jak rung a arawn alai, bungli galaw ai masa, shinggan grup yin masa ni, gram lajang ai lam hte hparan hpareng ai lam ni lawm ai. Ndai lam ni hpe hkum tsup ai hku myit yu nna, grau kaja hkra galaw ai hku nna sha, hka-} hka n-gun galai shai ai lam hpe ngang grin ai hku galaw lu na re.
