Unoziva here kuti nei iyo yakakwira uye yakaderera kudzvanywa kweiyo inotonhora yekuchengetedza system isina kujairika?

Iyo evaporating pressure, tembiricha uye condensing pressure uye tembiricha yefiriji system ndiyo mikuru paramita. Ihwo hwaro hwakakosha hwekushanda nekugadzirisa. Zvinoenderana nemamiriro chaiwo uye shanduko yehurongwa, maparamita anoshanda anoramba achigadziridzwa uye anodzorwa kuti ashande pasi pehupfumi uye anonzwisisika paramita, ayo anogona kuve nechokwadi chekuchengetedzwa kwemuchina, zvishandiso uye zvigadzirwa zvakachengetwa, kupa kutamba kwakazara kune kugona kwemidziyo, uye kuchengetedza mari. Mvura, magetsi, mafuta nezvimwe.

Chikonzeroofthe evaporation temperaturezvakaderera

1. Evaporator (inotonhorera) idiki zvakanyanya

Pane dambudziko mukugadzira, kana iyo chaiyo yekuchengetedza zvakasiyana-siyana zvakasiyana nekugadzirwa kwakarongwa kuchengetedza zvakasiyana-siyana, uye mutoro wekupisa unowedzera.

Solution:Iyo evaporator nzvimbo ye evaporator inofanira kuwedzerwa kana evaporator inofanira kutsiviwa.

2. Iyo compressor inotonhodza huwandu hwakanyanya

Mushure mokunge mutoro wekuchengetera zvinhu wakaderedzwa, simba re compressor harina kuderedzwa munguva. Iyo compressor yekuchengetera inotonhora inofananidzwa zvinoenderana neyakakura mutoro weiyo firiji system, uye iyo yakanyanya kuremerwa yemuchero uye yemiriwo inotonhorera yekuchengetedza inoitika panguva yekuchengetedza nhanho yezvinhu. Kazhinji yenguva, mutoro we compressor uri pasi pe50%. Kana tembiricha yekuchengetera inodonha kusvika kune yakakodzera yekuchengetedza tembiricha, iyo system mutoro inoderedzwa zvakanyanya. Kana muchina muhombe uchiri kuvhurwa, trolley hombe inodhonzwa nebhiza ichaumbwa, mutsauko wekushisa uchawedzera, uye kushandiswa kwesimba kuchawedzera.

Solution:kuderedza huwandu hwemacompressor akabatidzwa kana kuderedza huwandu hwemasilinda anoshanda ane simba rekudzora mudziyo zvinoenderana nekuchinja kwemutoro wedura.

3. Evaporator haina defrosted nenguva

Solution:Frost pane evaporator coil inoderedza kupisa kwekutamisa coefficient, inowedzera kupisa kwekupisa, inoderedza kupisa kwekuita, uye inoderedza kubuda kwefiriji. Kana simba re compressor richiramba risina kuchinjwa, evaporation pressure yegadziriro inoderera. Iyo inoenderana evaporation tembiricha inodzikira, saka defrost nenguva.

4. Pane mafuta ekuzora mu evaporator

Mafuta ekuzora ari muevaporator anozogadzira firimu remafuta pamadziro echubhu ye evaporating coil, iyo inozodzikisawo kupisa kweyekupisa coefficient, kuwedzera kupisa kwekupisa, kuderedza kupisa kwekuita, kuderedza kubuda kwefiriji, uye kuderedza evaporation pressure ye system. , iyo inopindirana yekupisa tembiricha inoderera, saka mafuta anofanira kudonhedzwa kuhurongwa munguva, uye mafuta ekuzora muevaporator anofanira kuburitswa nekupisa ammonia frosting.

5. Varuvhu yekuwedzera yakavhurika idiki

Kuvhura kwevhavha yekuwedzera idiki kwazvo, uye kupihwa kwemvura kwegadziriro idiki. Pasi pemamiriro ekugara kwe compressor simba, iyo evaporating pressure inodzikira, zvichikonzera kudzikira kwekupisa kwemhepo.

Solution:Dhigirii yekuvhura yevhavha yekuwedzera inofanira kuwedzerwa.

Zvinokonzera high condensing pressure

Kana iyo condensing pressure ichikwira, iyo compression basa ichawedzera, kutonhora kunoderera, iyo inotonhorera coefficient inoderera, uye kushandiswa kwesimba kuchawedzera. Inofungidzirwa kuti kana mamwe mamiriro anoramba asina kuchinjwa, kushandiswa kwesimba kuchawedzera neinenge 3% kune yega yega 1 ° C yekuwedzera mutembiricha yekupfupisa inoenderana nekutsikirira. Zvinowanzo fungwa kuti iyo yakanyanya hupfumi uye inonzwisisika condensing tembiricha ndeye 3 kusvika 5 °C yakakwirira kupfuura tembiricha yekubuda kwemvura inotonhorera.

Zvikonzero uye mhinduro dzekuwedzera kwekumanikidza kwecondenser:

1. Iyo condenser yakanyanya kudiki, tsiva kana kuwedzera condense.

2. Nhamba ye condensers yakaiswa mukushanda iduku, uye nhamba yekushanda inowedzera.

3. Kana mvura inotonhorera inoyerera isina kukwana, wedzera nhamba yemapombi emvura uye kuwedzera kuyerera kwemvura.

4. Kugoverwa kwemvura yeCondenser hakuna kuenzana.

5. Chiyero papiipi ye condenser inotungamirira kukuwedzera kwekudzivirira kupisa, uye hutano hwemvura hunofanira kuvandudzwa uye kuenzaniswa nenguva.

6. Pane mweya mucondenser. Mhepo iri mucondenser inowedzera kudzvinyirira kwechikamu muhurongwa uye kumanikidza kwese. Mhepo inoumbawo gasi gasi pamusoro peiyo condenser, zvichiita kuti kuwedzere kupisa kwekupisa, izvo zvinoderedza kupisa kwekushisa kwekushisa, zvichiita kuti condensation pressure uye condensation. Kana kutonhora kuchikwira, mhepo inofanira kusunungurwa nenguva.
