Kev hloov kho tsis raug lossis kev thaiv ntawm lub qhov txias txias throttle valve yuav cuam tshuam ncaj qha rau qhov ntws ntawm cov tub yees nkag mus rau hauv lub evaporator. Thaum lub throttle valve qhib loj heev, cov tub yees ntws loj, lub evaporation siab thiab evaporation kub kuj yuav nce, thiab qhov kub thiab txias ntawm lub warehouse yuav qeeb; Nyob rau tib lub sij hawm, thaum lub throttle valve me dhau los yog thaiv, cov tub yees txaus tus nqi kuj raug txo, lub peev xwm txias ntawm lub kaw lus kuj txo, thiab qhov kub thiab txias ntawm lub warehouse yuav tsum qeeb.
Kev daws: Feem ntau, seb lub throttle refrigerant flow rate puas tsim nyog tuaj yeem txiav txim siab los ntawm kev soj ntsuam cov evaporation siab, evaporation kub thiab frosting ntawm cov yeeb nkab suction. Lub throttle valve blockage yog ib qho tseem ceeb cuam tshuam rau cov tub yees txaus, thiab lub ntsiab yog vim li cas rau throttle valve blockage yog dej khov thiab qias neeg. Kev thaiv cov dej khov yog vim qhov tsis zoo ntawm lub tshuab ziab khaub ncaws, cov tub yees muaj cov dej noo, thaum ntws los ntawm lub qhov valve, qhov kub thiab txias poob qis dua 0 degree, thiab cov dej noo hauv cov tub yees khov thiab thaiv lub qhov throttle valve qhov; Kev thaiv qhov qias neeg yog vim muaj cov av ntau ntxiv ntawm cov ntxaij lim dej inlet ntawm lub throttle valve, thiab cov dej tsis zoo ntawm cov tub yees, tsim cov blockages.
