Lub tshuab chiller, tseem hu ua lub freezer, tub yees, lossis chav dej dej khov, feem ntau ua haujlwm kom tshem tawm cov kua vapor los ntawm compression lossis cua sov nqus cov tub yees, yog li ua tiav cov cua txias lossis cua sov. Lub tshuab chiller feem ntau muaj plaub ntu: compressor, evaporator, condenser, thiab expansion valve. Lub ntsiab compressor feem ntau yog cov ntsia hlau lossis centrifugal compressor, thaum cov chaw lag luam feem ntau yog siv scroll compressors.
Compressor: Lub compressor yog cov tseem ceeb ntawm lub chiller chav tsev, lub luag hauj lwm rau kos nyob rau hauv qis - kub, qis - siab refrigerant gas thiab compressing nws mus rau hauv ib tug siab - kub, siab - siab gas. Thaum lub sijhawm ua haujlwm no, ob qho tib si qhov kub thiab txias ntawm lub tub yees nce.
Evaporator: Hauv cov evaporator, cov tub yees hloov ntawm cov kua mus rau lub xeev gaseous, nqus cua sov los ntawm cov cua hauv tsev thiab txo nws qhov kub. Thaum cov txheej txheem no, ob qho tib si qhov kub thiab txias ntawm cov tub yees txo qis.
Qhuav Evaporator: Cov tub yees ntws hauv cov raj, thaum cov dej ntws tawm sab nraud ntawm lub raj ntim. Nws muaj lub plhaub, evaporator raj (sab hauv threaded raj), baffles, thiab kawg caps.
Flooded evaporator: Cov tub yees ntws tawm sab nraum cov raj, thaum dej ntws hauv. Nws muaj lub plhaub, cov raj evaporator (siab-cov khoom siv tau zoo), cov ntawv raj, thiab cov phaj txhawb nqa.
Poob zaj duab xis evaporator: Cov tub yees yog sib npaug ntawm cov khoom xa tawm, tsim cov yeeb yaj kiab ua kua rau ntawm qhov chaw ntawm cov cua kub sib txawv. Nws absorbs cua sov los ntawm sab hauv cov hlab ntsha thiab evaporates, thaum dej ntws mus rau hauv. Nws muaj cov khoom xa tawm, lub plhaub, cov raj evaporator (siab-cov raj ua haujlwm), cov ntawv raj, thiab cov phaj txhawb nqa.
