Peb cov spiral phaj kub exchanger tau ntse tsiv mus rau ib tug tshiab rhiav. Lub rooj cob qhia tshiab yog qhov loj dua thiab zoo dua hauv ib puag ncig, uas ua rau muaj kev txhim kho zoo rau lub tuam txhab cov txheej txheem ntau lawm.
Qhov loj me me ntawm lub rooj cob qhia tshiab muab TRANP nrog ntau qhov chaw tsim khoom thiab ua rau lub tuam txhab tuaj yeem npaj cov txheej txheem tsim khoom tau zoo dua. Raws li cov khoom tseem ceeb ntawm lub tuam txhab, cov txheej txheem ntau lawm ntawm kauv phaj kub exchanger yuav tsum tau tswj nruj thiab meej ua haujlwm. Lub spatial layout ntawm lub rooj cob qhia tshiab tau ua tib zoo tsim kom cov txheej txheem ntawm cov khoom siv ntau lawm yog qhov tsim nyog thiab kev ua haujlwm ntawm cov neeg ua haujlwm tau raug txhim kho.
Kev ua haujlwm ntawm lub rooj cob qhia tshiab yuav ntxiv dag zog rau TRANP lub peev xwm tsim khoom thiab kev sib tw, thiab muab cov neeg siv khoom zoo dua cov khoom thiab cov kev pabcuam.
