Unoziva here kudzikisa chando mukamuri inotonhora iyi-Defrost Heating Tube?

A. Muchidimbu

Nekuda kwechando chiri pamusoro peiyo evaporator munzvimbo inotonhora yekuchengetera, inodzivirira kuitisa uye kuparadzira inotonhora kugona kwefiriji evaporator (pipeline), uye pakupedzisira inokanganisa firiji mhedzisiro. Kana hupamhi hwechando chechando (chando) pamusoro peiyo evaporator inosvika kune imwe nhanho, kushanda kwefiriji kunyange kudonha kusvika pasi pe30%, zvichikonzera kuparara kukuru kwesimba remagetsi uye kupfupisa hupenyu hwebasa refiriji system. Naizvozvo, zvinodikanwa kuita inotonhora yekuchengetedza defrost oparesheni mukutenderera kwakakodzera. 

B. Chinangwa chekubvisa chando

1, kuvandudza kushanda kwefiriji yehurongwa;

2. Iva nechokwadi chemhando yezvigadzirwa zvechando mudura;

3, chengetedza simba;

4, wedzera hupenyu hwesevhisi yekutonhora yekuchengetedza system.

C. defrosting nzira

Cold storage defrosting nzira: gasi rinopisa defrosting (hot fluorine defrosting, hot ammonia defrosting), mvura defrosting, magetsi defrosting, mechanical (artificial) defrosting, etc.

1, gasi rinopisa defrost

Inokodzera hombe, yepakati uye diki yekuchengetera pombi defrosting:

Iyo inopisa-yepamusoro-tembiricha gaseous condensate inopinda zvakananga muevaporator pasina kubatwa, uye tembiricha ye evaporator inokwira, izvo zvinoita kuti chando chechando uye inotonhorera inoyerera inyunguduke kana kubviswa. Kupisa gasi defrosting ine hupfumi uye yakavimbika, yakanakira kugadzirisa uye manejimendi, uye mari yayo uye kuoma kwekuvaka hakuna kukura.

2, mvura yekupfapfaidza defrost

Inoshandiswa zvakanyanya mukudzikisa hombe uye yepakati chiller:

Nguva nenguva pfapfaidza evaporator nemvura yekudziya yekamuri kunyungudutsa chando. Kunyangwe iyo defrosting mhedzisiro yakanaka kwazvo, inonyanya kuenderana nemhepo inotonhorera, uye inonetsa kushanda kune evaporation makoiri. Zvinogoneka zvakare kupfapfaidza evaporator nemushonga une tembiricha yechando yakanyanya, senge 5% kusvika 8% concentrated brine, kudzivirira kuumbwa kwechando.

3, defrost yemagetsi

Iyo yemagetsi kupisa pombi inonyanya kushandiswa kune epakati uye diki chillers:

Iyo electric heat wire inonyanya kushandiswa kusvibisa yealuminium row chubhu yemagetsi kupisa mukati mepakati uye diki chengetedzo inotonhora, iri nyore uye nyore kushandisa kune chiller; Nekudaro, kune iyo nyaya yealuminium chubhu inotonhorera yekuchengetedza, kuoma kwekuvaka kwealuminium fin kuisirwa waya yemagetsi yekudziya hakusi kudiki, uye kutadza kuri kuita kwakakwira mune ramangwana, kuchengetedza uye kutonga kwakaoma, hupfumi hwakashata, uye iyo yekuchengetedza chinhu chakaderera.

4, mechanical artificial defrosting

Diki inotonhora yekuchengetera pombi defrosting application:

Cold storage pipe manual defrosting inowedzera mari, iyo yepakutanga defrosting nzira. Yakakura inotonhora yekuchengetera neyakagadzirwa defrosting haisi yechokwadi, kushanda kwemusoro kwakaoma, kushandiswa kwemuviri kunokurumidza, nguva yekuchengetedza muimba yekuchengetera yakarebesa uye inokuvadza kuhutano, defrosting haisi nyore kuve yakakwana, inogona kukonzera evaporator. deformation, uye inogona kutotyora iyo evaporator inotungamira kune tsaona yekudonha.

D. fluorine system defrosting nzira sarudzo

Zvinoenderana neyakasiyana evaporator yekuchengetera inotonhora, sarudza yakanyatsokodzera defrosting nzira. Nhamba diki dzezvitoro zvinotonhora zvidiki zvinoshandisa gonhi rakavharwa kuti risvibe nemhepo uchishandisa kupisa kwemhepo. Dzimwe tembiricha dzeraibhurari dzinopisa dzinosarudza kumisa firiji, kuvhura feni yekutonhora zvakasiyana, shandisa feni kutenderedza mhepo kuti isvibe, uye usagonese pombi yekupisa yemagetsi kuzadzisa chinangwa chekuchengetedza simba.

1, iyo nzira yekudzikisa yeinotonhorera:

(1) Kune yemagetsi chubhu defrosting uye mvura defrosting anogona kusarudzwa, nzvimbo dzine mvura zviri nyore vanogona kusarudza kusarudza mvura defrosting chiller, kushayikwa kwemvura nzvimbo vanosarudza kusarudza yemagetsi chubhu defrosting chiller.

(2) electric chubhu defrosting inonyanya kushandiswa mumhepo diki inotonhorera defrosting; Mvura inoyerera chando chiller inowanzo gadziridzwa muhombe air conditioning, firiji system.

2. Defrosting nzira yesimbi mutsara:

Kune inopisa fluorine defrosting uye artificial defrosting sarudzo.

3. Defrosting nzira yealuminium chubhu:

Kune thermal fluoride defrosting uye yemagetsi thermal defrosting sarudzo.

E. inotonhora yekuchengetedza defrosting nguva

Ikozvino yakawanda inotonhora yekuchengetedza defrosting inodzorwa zvinoenderana nedefrosting tembiricha probe kana defrosting nguva. Iyo defrosting frequency, nguva, uye defrosting yekumisa tembiricha inofanirwa kugadziridzwa zvichienderana nehuwandu uye mhando yezvinhu zvakaturikidzana.

Pakupera kwenguva yekudzikisa, uyezve kusvika kunguva yekudonha, fan inotanga. Chenjera kuti urege kuseta nguva yekudzikisa yakarebesa uye edza kuwana inonzwisisika defrosting. (Iyo defrosting kutenderera inowanzoenderana nemagetsi ekupa nguva kana iyo compressor yekutanga nguva.)

F. Kuongororwa kwezvikonzero zvechando chakanyanyisa

Pane zvikonzero zvakawanda zvinokanganisa kuumbwa kwechando, senge: evaporator chimiro, mhepo yemhepo (tembiricha, mwando) uye mwero wekuyerera kwemhepo. Mhedzisiro pakuumbwa kwechando uye kuita kwemhepo inotonhorera ndeiyi inotevera:

1, musiyano wetembiricha pakati pemhepo inopinza uye inotonhora yekuchengetedza fan;

2, hunyoro hwemhepo inofemerwa;

3, fin spacing;

4, inlet air flow rate.

Kana tembiricha yekuchengetera yakakwira kupfuura 8 ℃, yakajairwa inotonhora yekuchengetedza system inenge isingaite chando; Kana tembiricha yepakati iri -5℃ ~ 3℃ uye hunyoro hwemhepo hwakakura, mhepo inotonhorera iri nyore kuita chando; Kana tembiricha ye ambient yadzikiswa, kukurumidza kuumbwa kwechando kunodzikira nekuti mwando uri mumhepo unodzikira.
