Cov tub yees yuav tsum ua tau raws li cov qauv kev nyab xeeb hluav taws xob kom ntseeg tau tias lawv tsis ua rau muaj kev pheej hmoo ntawm kev raug hluav taws xob poob siab lossis hluav taws kub. Kev ua raws li National Electrical Code (NEC) yog qhov tseem ceeb.

 

Kev Nyab Xeeb Txog Tshuab

Cov tub yees yuav tsum tau tsim thiab ua kom tsawg kawg nkaus qhov kev pheej hmoo ntawm kev raug mob. Qhov no suav nrog kev ua kom muaj kev nyab xeeb ntawm cov khoom xws li kiv cua, compressors, thiab motors.

 

Kev Tswj Kub

Cov tub yees yuav tsum muaj peev xwm tswj tau qhov kub thiab txias kom zoo rau kev khaws cia zaub mov. Tus qauv yog kom sab hauv kub li ntawm lossis qis dua 40°F (4°C) kom ntseeg tau tias zaub mov muaj kev nyab xeeb.

 

Kev Nyab Xeeb ntawm Cov Tub Yees

Kev ua raws li cov qauv rau cov tshuaj txias yog qhov tseem ceeb heev los tiv thaiv kev puas tsuaj rau ib puag ncig thiab ua kom muaj kev nyab xeeb. Cov tshuaj txias yuav tsum tau kev pom zoo, thiab tus qauv tsim yuav tsum txo qhov kev pheej hmoo ntawm cov tshuaj txias xau.

 

Kev Siv Hluav Taws Xob Zoo

Cov tub yees feem ntau yuav tsum ua raws li cov cai ntawm kev siv hluav taws xob kom zoo, xws li daim ntawv pov thawj ENERGY STAR. Cov qauv no yog siv los txo kev siv hluav taws xob thiab kev tso pa roj av uas ua rau lub tsev cog khoom puas tsuaj.

 

Kev Nyab Xeeb Khoom Siv

Cov ntaub ntawv siv rau hauv kev tsim lub tub yees, suav nrog cov khoom rwb thaiv tsev thiab lwm yam khoom, yuav tsum muaj kev nyab xeeb thiab zoo rau ib puag ncig. Yuav tsum txo qis kev siv cov khoom phom sij.

 

Kev Tiv Thaiv Hluav Taws

Cov tub yees yuav tsum tsim los kom tiv taus hluav taws thiab tsis ua rau muaj kev phom sij ntawm hluav taws. Qhov no yuav suav nrog cov kev cai rau cov khoom siv thiab cov qauv tsim uas tiv taus hluav taws.

 

Kev Sau Npe thiab Kev Cim

Cov tub yees uas tau ntawv pov thawj feem ntau muaj lub cim ETL, qhia tias lawv ua tau raws li cov qauv kev nyab xeeb thiab kev ua tau zoo. Daim ntawv lo kuj tseem yuav muaj cov ntaub ntawv ntxiv xws li tus lej ntaub ntawv pov thawj.

 

Kev Ua Raws Li Cov Qauv Kev Lag Luam

Cov tub yees yuav tsum ua tau raws li cov qauv kev lag luam, suav nrog cov uas tau teeb tsa los ntawm cov koom haum xws li ETL, UL, thiab cov koom haum tswj hwm.

 

Kev Ntsuas Qhov Xaim Thiab Kev Ntsuas Siab

Cov tub yees uas muaj cov tshuab ua kom txias feem ntau raug kuaj xyuas qhov xau thiab qhov siab kom paub tseeb tias lawv kaw zoo thiab tsis ua rau muaj kev pheej hmoo ntawm cov khoom ua kom txias xau.

Cov lus qhia txog Yuav Ua Li Cas Thiaj Tau Txais Daim Ntawv Pov Thawj ETL Rau Cov Tub Yees Thiab Cov Khov Kho

ETL yog ib lub koom haum uas paub dav dav uas muab kev pabcuam kuaj thiab ntawv pov thawj. Nov yog qee cov lus qhia txog yuav ua li cas kom tau txais daim ntawv pov thawj ETL rau koj lub tub yees thiab lub tub yees khov:
