Koj tsis txhawb lub valve solenoid? Koj yuav tau tshem lub compressor – Qhov qhia txog qhov nqi uas cov neeg tsim chiller tsis pub tias

Thaum koj xa mus nrhiav chiller rau hauv tsev tsim, koj yuav pom tias cov chiller uas muaj qhov ntau ntawm qhov nqi ntau yuav muaj qhov nqi nyob rau hauv qhov sib piv ntau. Nyob rau hauv qhov nqi ntawm cov lus qhia thiab qhov sib txawv ntawm cov khoom, muaj ib qho "tsis pom" qhov nqi uas tsis muaj peb cov neeg xa mus nrhiav chiller pom – lub valve solenoid.

Cov neeg tsim chiller puav leej yuav tsis muaj lub khoom no los ntawm qhov nqi uas lawv tsim. Nws tsis muaj nyob rau hauv qhov sib piv ntawm cov lus qhia thaum lawv qhia koj, tab sis thaum chiller ua haujlwm, nws tsis muaj yuav ua rau koj tau nqi ntau dua qhov nqi uas koj tau txais.

Yog li cas, qhov kawg ntawm lub solenoid valve nyob rau hauv lub chiller tshwj xeeb yog dab tsi? Puas muaj qhov sib txawv loj rau qhov kev siv thiab tsis siv nws? Cov lus no pib ntawm qhov kev ua haujlwm thiab sau txog qhov kev xaum xyuam txog qhov kev siv thiab tsis siv nws.

1. Lub solenoid valve yog dab tsi thiab nws yuav ua dab tsi rau hauv lub system tshuaj sov?

Lub solenoid valve yog ib qho kawg uas tuaj yeem tshem tawm thiab tshem tawm los ntawm qhov hluav tais xob. Rau hauv lub system tshuaj sov, nws tau muab tso rau hauv lub thawv tshuaj sov thaum lub thawv tshuaj sov mus rau hauv lub expansion valve. Qhov kev ua haujlwm ntawm nws yog qhov tseem ceeb thiab qhov tseem ceeb heev:

- Muaj hluav tais xob → lub coil hluav tais xob ua qhov hluav tais xob, lub kawg ntawm kawg yuav mov, lub kawg yuav qhib, thiab lub tshuaj sov yuav dhau los.

- Tsis muaj hluav tais xob → qhov hluav tais xob yuav tawm, lub kawg ntawm kawg yuav rov qab, lub kawg yuav kho, thiab lub tshuaj sov yuav tsis dhau los.

Nyob rau hauv cov chiller tshwj xeeb thiab cov qhov cim txhawj nqa rau lub cev, lub valve solenoid feem ntau yog sib kooj nrog lub compressor. Thaum lub compressor pib, lub valve solenoid yuav qhib raws li; thaum lub compressor pauv, lub valve solenoid yuav khoob ua ntej lub compressor.

Lub qhov kev qhib thiab khoob no nyob rau hauv qhov kev nyab xaum thiab qhov sijhawm nyob rau hauv lub system ntawd.

2. Piv txwv 4 ntawm lub valve solenoid nyob rau hauv lub chiller tshwj xeeb

Piv txwv 1: Qhib tawm lub qhov tswv yim rau lub refrigerant thaum pauv kom tsis muaj "liquid slugging" – qhov uas puas lub compressor

Nyiag no yog qhov piv txwv tshwj xeeb tshaj plaws ntawm lub valve solenoid.

Thaum lub compressor pauv, yog tias muaj ntau refrigerant nyob rau hauv lub evaporator, lossis yog tias muaj refrigerant nyob rau hauv qhov nruab nrab ntau thiab muaj kev tshuaj tau los ntawm lub expansion valve mus rau hauv lub evaporator, ces thaum lub compressor pib dua, cov refrigerant no yuav tau qhib los rau hauv lub cylinder ntawm lub compressor.

No ntawv no yog qhov tshwm sim uas peb tsis xav tau – daim ntawv yog tsis tuaj yeem sib npaug, thiab thaum nws mus rau hauv cov khoom sib npaug nyob hauv qhov ntev, nws yuav ploj rau hauv cov khoom sib npaug uas muaj kev tswj hwm zoo, cov khoom sib npaug uas muaj kev tswj hwm zoo, cov khoom sib npaug uas muaj kev tswj hwm zoo, thiab lwm cov khoom sib npaug uas muaj kev tswj hwm zoo, uas ua rau:
