Kedu otu esi ahọrọ nchekwa oyi na usoro nchekwa oyi oyi?

1.Cold Nchekwa oyi ikike agụta
Ike oyi oyi nke nchekwa oyi nwere ike gbakọọ oriri jụrụ oyi nke nchekwa oyi, yana ọnọdụ ndị kachasị mkpa achọrọ:
Ngwaahịa
Ogo nchekwa oyi (ogologo * obosara * ịdị elu)
Ike nchekwa oyi
Olu azụrụ: T/D
Oge oyi: awa

Dị ka ahụmahụ, dị ka nha nke nchekwa oyi, a na-ekewa ya na ọnọdụ abụọ:
Atụmatụ nke ibu jụrụ oyi nke obere nchekwa oyi (n'okpuru 400m3).
Atụmatụ nke ibu jụrụ oyi nke nnukwu nchekwa oyi (n'elu 400m3).
 
A na-atụ anya ibu jụrụ oyi nke obere nchekwa oyi (n'okpuru 400m3):

Nchekwa okpomọkụ n'elu 0 ℃, evaporation okpomọkụ -10℃, 50～120W/m3;
Nchekwa okpomọkụ -18 ℃, evaporation okpomọkụ -28 ℃, 50～110W / m3;
Nchekwa okpomọkụ -25 ℃, evaporation okpomọkụ -33 ℃, 50～100W / m3;
The nchekwa okpomọkụ bụ -35 ° C, evaporation okpomọkụ bụ -43 ° C, 1 ton bi ebe 7m2, na jụrụ oyi oriri bụ 5KW / ton * ụbọchị; obere nchekwa oyi, ka oriri jụrụ oyi na-abawanye kwa otu olu.
 
A na-atụ anya ibu dị jụụ nke nnukwu nchekwa oyi (karịa 400m3):
 
Enwere ihe atụ abụọ maka nkọwa gị:
Nchekwa okpomọkụ 0～4℃, evaporation okpomọkụ -10℃
Site na ndabara, parampat ndị a:
Aha ngwaahịa: mkpụrụ osisi na akwụkwọ nri;
Ikike nchekwa (ton): 0.3 * 0.55 * oke nchekwa m3;
Olu ịzụta 8%;
Oge oyi - awa 24;
Ọnọdụ okpomọkụ na-abata: 25 ℃;
Mbupu okpomọkụ: 2℃.
Na ndabara ndabara, n'ibu ibu nke ọkara okpomọkụ nkwakọba: 25 ~ 40W / m3; nhazi nhazi: 4 ụlọ oyi; 90HP yiri unit na a ọkara okpomọkụ nkwakọba 1000㎡ * 4.5m elu.

Okpomọkụ oyi -18 ℃, evaporation okpomọkụ -28 ℃
 
Site na ndabara, parampat ndị a:
Aha ngwaahịa: anụ oyi kpọnwụrụ;
Ikike nchekwa (ton): 0.4 * 0.55 * oke nchekwa m3;
Olu ịzụta, 5%;
24 awa oyi oge;
Ọnọdụ okpomọkụ na-abata: -8 ℃;

Na paramita ndabara, ibu ọrụ nke ụlọ nkwakọba ihe dị ala bụ 18-35W / m3; nhazi nhazi: 4 ụlọ nkwakọba ihe oyi; 90HP ala okpomọkụ yiri unit na ala okpomọkụ nkwakọba 1000㎡ * 4.5m elu. Na paramita ndabara, ibu ọrụ nke ụlọ nkwakọba ihe dị ala: 18 ~ 35W / m3; nhazi nhazi: 4 ụlọ nkwakọba ihe oyi, igwe ịghasa + ECO; 75HP ala okpomọkụ yiri unit na ala okpomọkụ nkwakọba 1000㎡ * 4.5m elu.
 
Akpachara anya maka nhọrọ nke akụrụngwa nchekwa oyi: condenser: evaporative jụrụ mgbe ọnọdụ ọrụ na-agbanwe; Igwe nju oyi: nchekwa okpomọkụ dị elu na-eji obere okpomọkụ jụrụ oyi, mgbanwe okpomọkụ, valve mgbasa;
compressor: obere okpomọkụ compressor na-adọta nchekwa okpomọkụ dị elu;
ikuku na-ekpo ọkụ na-agbaze Frost: ụlọ nkwakọba ihe na-ekpo ọkụ ngwa ngwa;
mmiri na-agbapụta ntu oyi: mmiri ọkụ;
n'ala antifreeze: ventilashion, iyuzucha uzuoku ikpo ethylene glycol.
 
2. Nhọrọ nkeji nju oyi:

1. Otu otu na otu ụlọ nkwakọba ihe: otu ikike jụrụ oyi = 1.1 × ikike nke nchekwa oyi; ngụkọta ike dị jụụ nke usoro: ihe bara ụba 1.1-1.15 kwesịrị ịtụle.
2. Otu akụkụ nke nwere ọtụtụ ụlọ nkwakọba ihe: ike dị jụụ nke unit = 1.07 × nchikota nke ike oyi nke nchekwa oyi; ngụkọta ike dị jụụ nke usoro: 7% nke ọnwụ pipeline kwesịrị ịtụle.
3. Njikọ dị na ya na ọtụtụ nchekwa nchekwa oyi: unit jụrụ oyi = P × nchikota nke ike jụrụ oyi nke nchekwa oyi;
Ngụkọta ike jụrụ oyi nke sistemụ: mfu pipeline nke 7% na ọnụọgụ ọrụ ụlọ nkwakọba ihe n'otu oge kwesịrị ịtụle.
 
Ọnọdụ ndị dị mkpa maka nhọrọ igwe nju oyi:
ihe refrigerant;
oyi nchekwa okpomọkụ;
mgbanwe okpomọkụ;
Ọdịdị nke ikuku oyi;
Ogo nchekwa oyi, ikuku ọkọnọ anya;
Usoro ikpochapụ.
 
Ọnọdụ dị mkpa maka nhọrọ nke ikuku ikuku: 1. Refrigerant: Igwe ọkụ dị iche iche nwere mgbanwe okpomọkụ dị iche iche na nguzogide nrụgide. R404a nwere nnukwu mgbanwe okpomọkụ karịa R22, ihe dịka 1%. 2. Ọnọdụ nchekwa oyi: Na-ebelata okpomọkụ nchekwa oyi, obere mgbanwe okpomọkụ na nnukwu oghere mgbawa. Họrọ nke ọma oghere fin nke igwe nju oyi: nchikota;
Ngụkọta ike jụrụ oyi nke sistemụ: mfu pipeline nke 7% na ọnụọgụ ọrụ ụlọ nkwakọba ihe n'otu oge kwesịrị ịtụle.
 
3. Mgbanwe ọkụ:

Mgbanwe okpomọkụ nke ikuku oyi ≥ oriri oyi nke nchekwa oyi * 1.3 (mmetụta nke ntu oyi); mgbanwe okpomọkụ ọnụ: mgbanwe okpomọkụ na sample × n'ezie ọnụọgụ; mgbanwe okpomọkụ n'okpuru ọnọdụ nhazi: ọnụ ọgụgụ mgbanwe okpomọkụ × mgbazi ọnụọgụ; ọnụọgụ mmezi okpomọkụ nke nchekwa: na-ebelata okpomọkụ nke nchekwa oyi, obere mgbanwe okpomọkụ. Fin ihe mgbazi ihe: ihe na ọkpụrụkpụ. Nhazi nhazi nke mkpuchi fin: mkpuchi mgbochi corrosion na-ebelata mgbanwe okpomọkụ; ọnụọgụ mmezi olu ikuku: ihe pụrụ iche chọrọ maka fan.
 
4. Nhazi igwe nju oyi ikuku ụdị ụlọ:a na-ejikarị na nchekwa oyi;

Ụdị ụlọ: okpukpu abụọ nke ikuku ikuku, ikuku ikuku anọ, ikuku oyi;

Ụdị ala: ọnụ ụlọ na-ajụ oyi ngwa ngwa, ma ọ bụ ikuku duct refrigeration.

.Nha nke nchekwa oyi, ikuku na-enye anya, na nha nke nchekwa oyi, na-efesa ikuku nke ọma, ma chọpụta ọnụ ọgụgụ ndị na-ekpo ọkụ.
 
5. Nhọrọ nke defrosting usoro nke oyi nchekwa:
