1. Hakanya mojaro oa mocheso

Lebelo la mocheso le bolela tekanyo ea mocheso o lokelang ho tlosoa ho theola mocheso oa sepheo sa ho pholisa ho ea boemong bo itseng tlas'a tikoloho e itseng ea mocheso, 'me yuniti e le W (watt). Meroalo ea mocheso haholo-holo e kenyelletsa meroalo e sebetsang, meroalo e sa sebetseng, le metsoako ea eona. Mocheso o sebetsang oa mocheso ke mocheso oa mocheso o hlahisoang ke sepheo sa ho pholile ka boeona. Moroalo oa mocheso o sa sisinyeheng ke mojaro oa mocheso o bakoang ke mahlaseli a ka ntle, convection le conduction. Foromo e sebetsang ea ho bala mojaro

Qactive = V2/R = VI = I2R;

Qactive = Mojaro o sebetsang oa mocheso (W);

V = Matla a sebelisoang ho sepheo sa sehatsetsing (V);

R = Ho hanyetsa sepheo sa sehatsetsing;

I = Hajoale e phallang ka har'a sepheo se pholisitsoeng (A)

Radiant heat load ke mocheso o fetisetsoang nthong eo ho shebiloeng ho eona ka mahlaseli a motlakase. Foromo ea lipalo:

Qrad = F es A (Tamb4 – Tc4);

Qrad = Moroalo oa mocheso o khanyang (W);

F = sebopeho sa sebopeho (boleng bo bobe ka ho fetisisa = 1);

e = emissivity (boleng bo bobe ka ho fetisisa = 1);

s = Stefan-Boltzmann kamehla (5.667 X 10-8W / m² k4);

A = Sebaka se phodileng (m²);

Tamb = Mocheso o Tletseng (K);

Tc = TEC - Mocheso o batang oa ho qetela (K).

Convective heat load ke mocheso oa mocheso o fetisitsoeng ka tlhaho ke mokelikeli o fetang holim'a ntho e lebisitsoeng ho tsoa ka ntle. Foromo ea lipalo ke:

Qconv = hA (Tair – Tc);

Qconv = Moroalo oa mocheso oa Convective (W)

h = Coefficient ea ho fetisa mocheso (W/m ² °C) (boleng bo tloaelehileng ba sefofane sa metsi sebakeng se le seng se tloaelehileng) = 21.7 W/m² °C;

A = Sebaka sa bokaholimo (m²);

Tair = Mocheso oa tikoloho (°C);

Tc = Mocheso o batang oa ho qetela (°C);

Conductive mocheso mojaro ke mojaro oa mocheso o fetisetsoang ho tsoa ka ntle ka lintho tse amanang le tsona holim'a ntho e lebisitsoeng. Foromo ea lipalo ke:

Qcond =k A DT/L;

Qcond = Moroalo o fetisitsoeng oa mocheso (W);

k = Thermal conductivity ea thepa e tsamaisang mocheso (W / m ° C);

A = Sebaka sa sefapano sa thepa e tsamaisang mocheso (m²);

L = Bolelele ba tsela ea ho tsamaisa mocheso (m)

DT = Phapang ea thempereichara ea tsela ea ho tsamaisa mocheso (°C) (hangata e bua ka thempereichara e tikolohong kapa mocheso oa teba ha ho tlosoe mocheso o batang oa pheletso.)

Bakeng sa mojaro oa mocheso o kopaneng oa convection le conduction, foromo ea lipalo ke:

Q passive = (A x DT)/(x/k + 1/h);

Qpassive = Mojaro oa mocheso (W);

A = Kakaretso ea sebaka sa holim'a khetla (m2);

x = Botenya ba lera la insuela (m)

k = Insulation conductivity thermal conductivity (W/m °C);

h = Coefficient ea ho fetisa mocheso (W/m² °C)

DT = Phapang ea mocheso (°C).

2. Bala palo eohle ea mocheso oa mocheso

Ka mohato oa pele, re ka bala palo eohle ea mocheso oa sepheo sa sehatsetsing.

Ha re re ka morero oa sebele, mocheso o sebetsang oa mocheso ke 8W, mocheso o khanyang oa mocheso ke 0.2W, mocheso oa convective ke 0.8W, mocheso oa mocheso o tsamaisang ke 0W, 'me mocheso oohle oa mocheso ke 9W.

3. Hlalosa mocheso

Hlalosa mocheso o chesang oa ho qetela, mocheso o batang oa ho qetela le phapang ea mocheso oa sehatsetsi oa lakane ea sehatsetsi. Ha re re morerong oa sebele, mocheso o teng ke 27°C, mocheso o batang ke -8°C, le phapang ea mocheso o pholileng ke DT=35°C.

Ho nka hore mocheso o felletseng oa sepheo sa ho pholisa o hakanngoa hore ke 9W ho latela khakanyo e fetileng, Qmax e nepahetseng e ka fumanoa e le 9/0.25=36W, le Qmax e phahameng e le 9/0.45=20.
