Kutonhora kwekushisa -18 ℃, evaporation tembiricha -28 ℃
 
By default zvinotevera parameters:
Zita rezvinhu: nyama yechando;
Kuchengetedza simba (matani): 0.4 * 0.55 * vhoriyamu yekuchengetedza m3;
Kutenga vhoriyamu, 5%;
24 maawa ekutonhora nguva;
Kupinda tembiricha: -8 ℃;
Kutakura tembiricha: -18 ℃.
Mune zvigadziriswe zvimiro, iyo mechanical load ye yakaderera tembiricha warehouse iri 18-35W/m3; yakajairika kugadzirisa: 4 inotonhora matura; 90HP yakaderera tembiricha parallel unit ine yakaderera tembiricha yekuchengetera 1000㎡* 4.5m kureba. Mune zvigadziriso zvigadziriso, iyo mechanical load ye yakaderera tembiricha warehouse: 18 ~ 35W/m3; yakajairwa gadziriso: 4 inotonhora matura, screw muchina + ECO; 75HP yakaderera tembiricha parallel unit ine yakaderera tembiricha yekuchengetera 1000㎡* 4.5m yakakwirira.
 
Kuchengetedza kusarudzwa kwemidziyo yekuchengetedza inotonhora: condenser: evaporative cooling kana mamiriro ekushanda achichinja; mhepo inotonhorera: yakakwirira tembiricha yekuchengetedza inoshandisa yakaderera tembiricha kutonhora fan, kupisa kupisa, kuwedzera vharafu;
compressor: yakaderera tembiricha compressor inodhonza yakakwirira tembiricha kuchengetedza;
mhepo inopisa inonyungudusa Frost: inokurumidza-kutonhora imba yekuchengetera;
mvura inoyerera chando: tembiricha yemvura;
pasi antifreeze: kufefetedza, kupera simba kupisa ethylene glycol.
 
2. Kutonhodza kunopfupikisa Sarudzo yeChikwata:

1. Single unit uye imba yekuchengetera imwe chete: unit cooling capacity = 1.1 × inotonhorera inotonhorera yekuchengetedza inotonhora; yakazara kutonhora kugona kweiyo system: iyo hupfumi chinhu 1.1-1.15 inofanirwa kutariswa.
2. Imwe yuniti ine matura akawanda: kutonhora kwechikwata = 1.07 × huwandu hwekutonhodza huwandu hwekuchengetedza kutonhora; iyo yakazara yekutonhodza simba rehurongwa: 7% yekurasikirwa kwepombi kunofanirwa kutariswa.
3. Parallel unit ine akawanda anotonhora storages: unit cooling capacity = P × sum of cooling capacity of cold storage;
Iyo yakazara yekutonhodza kugona kweiyo system: iyo yekurasikirwa kwepombi ye7% uye yekuchengetera basa coefficient pamusoro penguva imwe chete inofanirwa kutariswa.
 
Mamiriro ezvinhu anodiwa pakusarudza mhepo inotonhorera:
The refrigerant;
kutonhora kuchengetedza tembiricha;
kupisa kupisa;
Chimiro chemhepo inotonhorera;
Cold storage size, air supply distance;
Defrost nzira.
 
Mamiriro ezvinhu anodiwa pakusarudza mhepo inotonhorera: 1. Refrigerant: Mafiriji akasiyana-siyana ane kusiyana kwakasiyana kwekupisa uye kusagadzikana kwekumanikidza. R404a ine hombe yekutsinhanisa kupisa kupfuura R22, inenge 1%. 2. Kutonhora kwekuchengetera tembiricha: Kudzikira tembiricha yekuchengetera, kudiki kuchinjisa kupisa uye kukura kwe chip spacing. Nemazvo sarudza fin spacing yemhepo inotonhorera: sum;
Iyo yakazara yekutonhodza kugona kweiyo system: iyo yekurasikirwa kwepombi ye7% uye yekuchengetera basa coefficient pamusoro penguva imwe chete inofanirwa kutariswa.
 
3. Kuchinjanisa kupisa:

Kutsinhana kwekupisa kwemhepo inotonhorera ≥ iyo inotonhorera inotonhorera yekuchengetedza inotonhora * 1.3 (mhedzisiro yechando); iyo yezita rekutsinhanisa kupisa: kupisa kunopisa mumuenzaniso × iyo chaiyo coefficient; kupisa kunopisa pasi pemamiriro ekugadzirisa: zita rekushandura Heat × kugadzirisa coefficient; kuchengetedza tembiricha kugadzirisa coefficient: kuderera kwekushisa kwekutonhora kwekuchengetedza, kuduku kuchinja kwekushisa. Fin material correction factor: zvinhu uye ukobvu. Kugadziriswa kwekofi yefin coating: anti-corrosion coating inoderedza kupisa kupisa; air volume correction coefficient: zvakakosha zvinodiwa kune fan.
 
4. Mhepo inotonhorera chimiro Ceiling type:inowanzoshandiswa mukuchengetedza kunotonhora;

Sirin'i rudzi: kaviri mhepo yekubuda, ina mhepo yekubuda, air conditioner;

Froor type: Inokurumidza kutonhora kamuri, kana air duct firiji.

.Saizi yekuchengetera inotonhora, chinhambwe chekupa mhepo, uye saizi yekuchengetera inotonhora, zvakaenzana kuvhuvhuta mweya, uye kuona huwandu hwemafeni ekutonhodza.
 
5. Sarudzo yekusvibisa nzira yekuchengetedza inotonhora:
