Ndingaziva sei kana chinhu changu che defrost heater chisina kunaka?

Iyohita yekunyungudutsainonyungudutsa chando nechando zvakaunganidzwa pa evaporator coil yefiriji kana firiji. Chinhu chinoshanda mu defrost heater ndechekupisa evaporator coil, kunyungudutsa ice uye kuburitsa mvura.chinhu chekupisa chandoinoshandiswa kudzivirira firiji kuti isaome uye inodzorwa nethermostat. Munguva yekunyungudutsa, hita inonyungudutsa chando chiri pamafin evaporator.

Mahita ekunyungudutsaZvinodiwa pakunyungudutsa chando chakaunganidzwa pamakoiri e evaporator emidziyo yekutengeserana yekutonhodza. Kana chando chaumbwa pakoiri ye evaporator, chinogona kukanganisa zvakanyanya mashandiro emudziyo wese, izvo zvinoita kuti zvive zvakakosha kuchengetedza hita inonyungudutsa ichishanda zvakanaka pafiriji nefiriji.

Saka ungaziva sei kana chubhu yekudzikisa chando yakakuvara?

Yakakuvarachubhu yekudzikisa chandozvinogona kukonzera kuumbwa kwechando chakawanda pa evaporator coil, nokudaro zvichikwidza tembiricha mukati mefiriji kana firiji. Unogona zvakare kushandisa multimeter kuyedza conductivity yayo uye resistance, izvo zvicharatidza kana hita iri kushanda nemazvo.

Zviratidzo zvekukuvadzwa kweheater inonyungudutsa

1. Kuumbwa kwechando kwakanyanya

Kana ukaona kuti pane chando chakawanda pa evaporator coil kupfuura zvakajairika, ichi chingave chiratidzo chakasimba chekutihita yekudziya mufirijiyava kuda kukuvara.

2. Kukwira kwekupisa

Firiji kana firiji zvinogona kunge zvisina kusvika patembiricha yakaderera inotarisirwa, kana kuti panogona kunge paine kuchinja-chinja kwetembiricha.

3. Kutenderera kwekuchenesa nemaoko

Kana ukatanga kunyungudutsa nemaoko asi hita ikasapisa, inogona kunge yakakuvara.

4. Bvunzo rekufambisa mhepo

Shandisa multimeter, isa pa ohm range, wobva wabata probe kuma terminals eheater.

5. Kuramba:

Chidziyo chakanaka chinonyungudutsa mvura chinofanira kunge chine simba rekudzivirira, iro, maererano nemamwe mashoko, rinowanzova pakati pe20 ne100 ohms. Kuenderera mberi: Kana pasina kuenderera mberi (mudziyo unoratidza circuit yakavhurika), chidziyo chinogona kukuvara.

Kana ukaona kutihita yekunyungudutsaKana yakakuvara, inoda kutsiviwa. Kutsiva hita kungave kuri nyore kuita, asi nguva dzose zvakanaka kutarisa bhuku rekushandisa kana kugadzirisa vhidhiyo yemhando yako yefiriji.
