Kuwonjezedwa kwachindunji (DX) kutentha kwa kutentha ndi kuyeretsa mpweya wa mpweya ndi gawo lothandizira mpweya lomwe limagwiritsa ntchito mpweya monga gwero la kuzizira ndi kutentha, ndipo ndi chipangizo chophatikizira chazomwe zimazizira komanso kutentha.Amakhala ndi panja mpweya utakhazikika psinjika condensing gawo (kunja unit) amene amapereka ozizira ndi kutentha sing'anga ndi m'nyumba unit gawo (m'nyumba unit) amene ali ndi udindo mankhwala mpweya, amene mwachindunji chikugwirizana kudzera refrigerant mapaipi.Chigawo chowongolera mpweya cha DX sichifuna nsanja zozizirira, mapampu amadzi ozizira, ma boilers ndi zida zina zothandizira mapaipi.Dongosolo la AHU ndi losavuta, lopulumutsa malo, komanso losavuta kukhazikitsa ndi kukonza.

HOLTOP HJK mndandanda wa mayunitsi a DX obwezeretsa kutentha ndi kuyeretsa mpweya amatengera ukadaulo wa HOLTOP wobwezeretsa kutentha, pogwiritsa ntchito zida zapamwamba zamtundu wa firiji, zodzipangira zokha komanso zopangidwa ndi zida zozizira komanso zotentha.Magawo ogwiritsira ntchito mpweya amatha kukhala ndi zida zosiyanasiyana zochotsera kutentha, monga zosinthira kutentha kwa rotary, zosinthira ma plate fin heat exchanger ndi ma plate heat exchanger kuti apezenso mphamvu kuchokera ku mpweya wotulutsa ndikupulumutsa mphamvu.Panthawi imodzimodziyo, imatha kukhazikitsidwa ndi zigawo zosiyanasiyana zogwira ntchito monga kusefera, kutentha ndi chinyezi kuti zikwaniritse zosowa zosiyanasiyana za chitonthozo ndi ndondomeko.Kupatula apo, mawonekedwe owoneka bwino komanso kutsika kwapang'onopang'ono kwa mpweya kumakwaniritsa mulingo wa kuyeretsa mpweya.

Poyerekeza ndi machitidwe ena apakati komanso apakati, mawonekedwe a DX Coil Air Handling system ndi osavuta komanso osinthika, motero amagwiritsidwa ntchito kwambiri m'malo ogulitsira, nyumba zamaofesi, zipinda, zisudzo, masukulu ndi malo ena.
