1.Basic Working Principple
Tub yees txheej txheem
1) Compression: Ammonia roj yog pressurized los ntawm lub compressor mus rau hauv siab - kub thiab siab - roj siab (xws li 25bar, 80℃).
2) Condensation: High -kub ammonia gas yog txias rau hauv lub condenser los ntawm dej los yog cua, liquefying thiab tso cua sov.
3) Throttling: Kua ammonia yog depressurized los ntawm ib tug expansion valve, thiab nws kub poob sharply mus rau lub evaporation kub (xws li -30 degree).
4) evaporation: Tsawg-kub kua ammonia absorbs tshav kub thiab vaporizes nyob rau hauv lub evaporator, ua tiav cov tub yees.
5) COP: COP ntawm ammonia system feem ntau yog 3.5 txog 6.0, uas yog ntau dua li ntawm Freon (R22 COP≈3.0).
2. Cov ntsiab lus tseem ceeb
1) Ammonia compressor: Nws muab lub zog thiab muab faib ua piston hom, hom ntsia hlau thiab hom centrifugal
2) Evaporative condenser: Lub tshav kub hloov pauv feem ntau yog lub plhaub thiab lub raj hom lossis phaj hom
3) Reservoir: Khaws cov kua ammonia thiab sib npaug ntawm qhov system load
4) Kev tswj hwm kev nyab xeeb: Saib xyuas cov ammonia concentration, siab thiab kub kom ua rau muaj kev kub ntxhov
3. Core Advantage
1) Eco-tus phooj ywg: ODP ntawm ammonia yog 0 (tsis ua puas rau cov txheej txheem ozone), thiab GWP yog 0 (tsis muaj cov nyhuv tsev cog khoom), uas yog raws li Montreal raws tu qauv.
2) Kev lag luam kev lag luam: Tus nqi ntawm ammonia tsuas yog 1/5 ntawm Freon, thiab nws cov kev siv hluav taws xob siv tsawg (txuag tshaj 30% ntawm hluav taws xob).
3) High - tub yees ua tau zoo: Nws muaj cov cua sov loj ntawm evaporation (1370 kJ / kg, uas yog tsib npaug ntawm R22) thiab haum rau qhov kub ntau ntawm -50℃txog 10℃.
4. Daim ntawv thov
1) Khoom noj khoom haus khov: ceev- lub tsev khov khov khov (-35 degree), cov hlua txias (xws li tuna ua).
2) Chemical tub yees: Txias ntawm ammonia synthesis nroj tsuag thiab petrochemical cov hlab ntsha.
3) Cold chain logistics: Cov chaw txias txias loj (xws li JD Asia No.1 Warehouse).
5. Kev nyab xeeb thiab kev tswj hwm
1) Kev nyab xeeb kev nyab xeeb: Ammonia yog tshuaj lom (IDLH=300ppm) thiab nplaim taws (tsawg kawg 15% - 28%), thiab yuav tsum muaj kev tiv thaiv nruj.
2) Tus qauv tsim
International: ISO 5149, IIAR (International Institute for Ammonia Refrigeration) cov qauv.
Tuam Tshoj: GB 50072-2021 "Code for Design of Cold Storage" mandatorily yuav tsum tau saib xyuas cov dej xau thiab tsim pov thawj tawg.
3) Kev ntsuas kub ceev
Txhawm rau nruab ammonia gas sensors thiab lub tshuab nqus dej, cov neeg ua haujlwm yuav tsum tuav cov ntawv pov thawj cuam tshuam (xws li daim ntawv pov thawj kev ua haujlwm siab ntawm lub nkoj).
6. Kev sib piv nrog Freon system
Ammonia System Freon qhov system (R404A)
Kev ua kom txias txias siab (COP Ntau dua lossis sib npaug rau 4.0) Nruab Nrab (COP≈3.0)
Eco-tus phooj ywg zoo heev (ODP=0, GWP=0) Poor (GWP=3922)
Kev tswj hwm nruj nruj yuav tsum muaj kev nyab xeeb (Class A1)
Cov nqi pib pib siab dua (kwv yees li 30% ntau dua) qis dua
