Dab tsi yog qhov kev ua tau zoo ntawm cov tub yees?

Yog tias lub chiller tuaj yeem ua haujlwm ib txwm thiab nyab xeeb, cov tub yees yog qhov tseem ceeb. Nws yog ib qho kev ua haujlwm nruab nrab uas circulates hauv lub chiller tub yees kom ua tiav cov tub yees, thiab tseem hu ua lub tub yees ua haujlwm nruab nrab lossis tub yees. Yog li, dab tsi yog qhov kev ua tau zoo ntawm cov tub yees rau cov chillers ntawm cov tub yees sib txawv?

1. Thermodynamic zog [plating chiller]

1. Nws yuav tsum muaj qhov nruab nrab saturated chav siab. Evaporating siab feem ntau yuav tsum tsis txhob qis dua atmospheric siab kom tsis txhob muaj cua nkag mus rau hauv lub cev (siv cov ntsia hlau chiller / cua txias chiller / dej txias chiller ua piv txwv); lub condensing siab yuav tsum tsis txhob siab dhau heev lawm, txwv tsis pub lub siab kuj yuav tsum tau ntawm lub system yuav raug cuam tshuam. Nce, thiab yuav nce lub zog noj; Tsis tas li ntawd, qhov sib piv ntawm condensing siab rau evaporating siab yuav tsum tsis txhob siab dhau, txwv tsis pub nws yuav ua rau compressor tawm kub ntawm lub chiller nce.

2. Nws yuav tsum muaj qhov kub thiab txias siab dua (ntau tshaj qhov ntsuas kub ntawm qhov nruab nrab), kom nws tuaj yeem ua kua dej ntawm chav tsev kub lossis qhov kub tsis zoo, thiab qhov poob qis yuav raug txo.

3. Nws yuav tsum muaj qhov kub thiab txias. Qhov no tiv thaiv lub refrigerant los ntawm khov ntawm evaporating kub.

4. Nws yuav tsum muaj thermal conductivity ntau dua. Qhov no tuaj yeem ua rau kom cov cua sov hloov coefficient ntawm cov hluav taws xob sib hloov ntawm lub chiller (nqa cov ntsia hlau chiller / cua txias chiller / dej txias chiller ua piv txwv), txo qhov kub hloov chaw, thiab txo cov nqi tsim khoom thiab kev ua haujlwm.

5. Yuav tsum muaj qhov ntsuas me me adiabatic. Qhov no tuaj yeem ua rau cov txheej txheem compression haus tsawg zog, thiab compressor tawm kub yuav tsis siab dhau.

6. Lub peev xwm tshwj xeeb kub ntawm cov kua tub yees yog me dua. Qhov no tuaj yeem txo cov txheej txheem throttling poob.

2. Kev ua haujlwm ntawm lub cev thiab tshuaj lom neeg [cua txias chiller]

1. Nws yuav tsum muaj ib tug me me ceev thiab viscosity, uas muaj peev xwm txo tau cov khiav kuj poob ntawm refrigerant nyob rau hauv lub chav tsev tub yees system (coj cov ntsia hlau chiller / cua-txias chiller / dej-txias chiller li ib qho piv txwv).

2. Nws yuav tsum tsis txhob tawg, tawg, tsis muaj tshuaj lom, thiab tsis yooj yim rau decompose nyob rau hauv qhov kub thiab txias, thiab tsis yooj yim rau corrode cov hlau qhov chaw ntawm lub chiller.
