(7) Nruam ze ntawm lub compressor kua cia tank, siv los xyuas cov kua rov qab yeeb nkab kub. Lub ntsiab installation txoj hauj lwm ntawm cov av noo sensor: Ib tug humidity sensor yog ntsia nyob rau hauv lub pa duct mus ntes cov huab cua humidity.
Kub sensor yog ib qho tseem ceeb ntawm cov cua txias system. Nws lub luag haujlwm yog txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhav, nws nws lub luag haujlwm zoo Txhawm rau kom hloov kho qhov kub ntawm chav tsev, lub siab thiab qis cua txias system yuav tsum tau nruab nrog cov ntsuas kub. Muaj ntau hom kub sensors, tab sis feem ntau muaj ob hom siv hauv tsev cua txias tshuab: thermistor (electronic thermostat) thiab thermal expansion kub sensor (bollows thermostat, diaphragm box thermostat hu ua mechanical thermostat). Tam sim no, thermistor kub sensor yog dav siv, thiab txhua yam kub maub los yog feem ntau siv nyob rau hauv ib tug txias cua txias. Raws li txoj kev ntsuas, nws tuaj yeem muab faib ua hom kev sib cuag thiab tsis sib cuag, thiab raws li cov yam ntxwv ntawm cov khoom siv sensor thiab cov khoom siv hluav taws xob, nws tuaj yeem muab faib ua thermal resistance thiab thermocouple. Lub luag haujlwm tseem ceeb thiab kev ua haujlwm ntawm lub tshuab cua txias qhov ntsuas kub yog raws li hauv qab no:
1. Sab hauv ib puag ncig qhov kub thiab txias sensor: sab hauv tsev ib puag ncig kub sensor feem ntau yog ntsia rau hauv qhov hluav taws xob cua ntawm chav tsev kub exchanger, nws lub luag hauj lwm yog peb:
(1) Qhov ntsuas kub ntawm chav tsev tau kuaj pom thaum lub tub yees lossis cua sov, thiab lub sijhawm ua haujlwm ntawm lub compressor raug tswj.
(2) Tswj lub xeev ua haujlwm raws li kev ua haujlwm tsis siv neeg;
(3) Txhawm rau tswj qhov ceev ntawm kiv cua hauv chav.
2. Sab hauv tsev coil kub sensor: sab hauv tsev coil kub sensor nrog lub plhaub hlau, ntsia rau ntawm qhov chaw ntawm lub tshav kub hauv tsev, nws lub luag haujlwm tseem ceeb muaj plaub:
(1) Kev tswj hwm kev pheej hmoo rau kev tiv thaiv khaub thuas hauv lub caij ntuj no cua sov.
⑵ Siv los tiv thaiv kev tiv thaiv kom khov rau lub caij ntuj sov lub tub yees.
(3) Nws yog siv los tswj cov cua hauv tsev.
(4) Koom tes nrog cov nti kom paub qhov txhaum.
(5) Tswj lub frosting ntawm sab nraum zoov chav tsev thaum cua sov.
3. Sab nraum zoov ib puag ncig kub sensor: sab nraum zoov ib puag ncig kub sensor los ntawm cov yas thav duab ntsia rau sab nraum zoov kub exchanger, nws lub luag hauj lwm tseem ceeb muaj ob:
(1) txhawm rau txheeb xyuas qhov kub ntawm qhov chaw sab nraud thaum lub tub yees lossis cua sov;
(2) Qhov thib ob yog tswj kev ceev ntawm cov kiv cua sab nraum zoov.
4. Sab nraum zoov coil kub sensor: sab nraum zoov coil kub sensor nrog hlau plhaub, ntsia rau ntawm qhov chaw ntawm lub tshav kub exchanger, nws lub luag hauj lwm tseem ceeb muaj peb:
(1) Kev tiv thaiv tiv thaiv overheating thaum lub tub yees;
(2) Anti-freezing tiv thaiv thaum cua sov;
(3) Tswj qhov kub thiab txias ntawm lub tshav kub exchanger thaum lub sij hawm defrosting.
5. Compressor cua kub sensor: compressor cua kub sensor kuj yog ua los ntawm cov hlau plhaub, nws yog ntsia rau ntawm compressor tso yeeb nkab, nws lub luag hauj lwm tseem ceeb muaj ob:
(1) Los ntawm kev kuaj xyuas qhov kub thiab txias ntawm compressor tso cov yeeb nkab, tswj qhov qhib qhov kev nthuav dav valve compressor ceev;
(2) Siv rau cov yeeb nkab tso cua sov tiv thaiv.
Lub tswv yim, feem ntau manufacturers raws li cov cua txias nyob rau hauv tsev microcomputer tswj motherboard tsis mus txiav txim tus nqi kuj ntawm qhov kub thiab txias sensor yog, feem ntau thaum tus nqi kuj txo nrog qhov kub thiab txias, nce nrog rau qhov kub thiab txias.
