Jekete yotchinjiriza yochotsa imatha kugwiritsidwa ntchito m'magawo osiyanasiyana; monga malo opangira mo?a, mafakitale a zakumwa, mafakitale a zakudya, mafakitale a mankhwala, mafakitale ogulitsa mankhwala, zombo, maloboti a mafakitale ndi zina zotero.

Chochotsa matenthedwe kutchinjiriza jekete (mafakitale matenthedwe kutchinjiriza jekete) chimene chimagwiritsidwa ntchito kwambiri ndi zimene ketulo matenthedwe kutchinjiriza jekete, magetsi limodzi ndi kutentha (kutentha magetsi) matenthedwe kutchinjiriza jekete, sitima yapamadzi (vavu) matenthedwe kutchinjiriza jekete, jekeseni akamaumba mbiya (mfuti mbiya) matenthedwe kutchinjiriza jekete / chivundikiro, manhole, heterogeneous pa sormal insulation jekete.

1). Mtundu wa kutentha kwapakati: sungani kutentha kwapakati pachitetezo, poletsa kusinthanitsa kutentha kwapakati ndi kunja kwa mphamvu (convection, radiation, ndi transfer), onetsetsani

kutentha kwa kupanga, kuonjezera mphamvu ya kutentha, izi zidzapulumutsa mphamvu.

2). kukana mtundu wa ma radiation akunja: kukana kutentha kwakunja kwamphamvu kuti musatenge kutentha kwakunja kupita mkati komwe kungakhudze kutentha kwachitetezo ndikuwononga zida, gawo, chida.

3). Mtundu wa antifreezing: kukana kwathu kutentha kochepa kumakhudza kutentha kwachitetezo. Mtundu uwu umagwiritsidwa ntchito makamaka kuteteza payipi, zida, chida. Zomwe zimagwiritsidwa ntchito popanga chophimbachi zimaganiziridwa ndi pempho la komweko.

4). Kusunga kutentha kochepa: sungani kutentha kwakunja kupita mkati komwe kungakhudze choteteza kutentha.

5). Mtundu wa calefaction: kuti akwaniritse pempho la kupanga, kapena kukana kuzizira, zida ndi mapaipi angafunike kutenthedwa, panthawiyi amafunika kukhala ndi chophimba kuti asatenthe.
