Zipangizo zoziziritsira (compressor unit) zimayikidwa m'chipinda cha makina, ndipo malo ozungulira ayenera kusamalidwa:
1. Payenera kukhala malo omveka bwino osapitirira 1.5m kutalika kwa compressor yoziziritsira, malo omveka bwino osapitirira 0.6~1.5m kutsogolo ndi kumbuyo, ndi malo omveka bwino osapitirira 0.6m kumapeto kwina moyang'anizana ndi khoma kumbali yakumanzere ndi yakumanja, ndipo osapitirira 0.6m kumapeto kwina. Malo omveka bwino osapitirira 0.9~1.2m.
2. Kutentha kwa malo ozungulira sikuyenera kupitirira 10℃.
3. Chipangizocho chikayikidwa panja, payenera kukhala malo otetezera mphepo, mvula ndi dzuwa, ndipo njira ziyenera kutengedwa kuti zisawonongeke komanso kuonetsetsa kuti magetsi akuteteza. Chiyenera kuchotsedwa ku magwero otentha kwambiri, zinthu zoyaka moto ndi zophulika kapena zotengera zophulika.
4. Makinawo ayenera kukhala otetezedwa ku kugunda kwa mtima komanso osamveka bwino.
Zofunikira pakupanga zida zoziziritsira:
1. Maziko a zida zoziziritsira (compressor unit) ayenera kukhala ndi mphamvu zokwanira, ndipo maziko a konkriti ayenera kuikidwa pansi pa nthaka. Nthawi zambiri kulemera kwa maziko kumakhala pafupifupi kawiri mpaka kasanu kuposa kulemera kwa chipangizo choziziritsira. Pa mayunitsi ang'onoang'ono ndi apakatikati, ma compressor ndi ma mota oziziritsira amatha kuyikidwa pa chassis wamba poyamba, kenako nkuyikidwa pa maziko.
2. Zipangizo zoziziritsira (compressor unit) ziyenera kuyikidwa mopingasa, ndipo ma pad okhala ndi mawonekedwe ofanana ndi a wedge okhala ndi kulondola komwe kulipo osachepera 0.02 ~ 0.05mm/m2 angagwiritsidwe ntchito pokonza ma level. Pofuna kuchepetsa kugwedezeka ndi phokoso, zida zoyamwa ma shock, monga ma pad a rabara oyamwa ma shock, ma spring, ndi zina zotero, ziyenera kuyikidwa pakati pa maziko a makina ndi maziko.
3. Lamba wa compressor yoziziritsira ali molunjika ndipo ali ofanana ndi mlatho wa pulley ya mota, ndipo kulimba kwa lamba kuyenera kukhala koyenera. Njira yowunikira ndikukanikiza malo apakati a lamba ndi dzanja, ndipo lamba wokhala mkati mwa 100mm m'litali ndi wopindika pafupifupi 1mm ndi woyenera.
4. Kuyesa kuthamanga kwa mpweya kwa 176.4N/cm2 ndikofunikira poyika condenser. Chitoliro chotulutsira condenser chiyenera kupendekeka kupita ku accumulator, yokhala ndi malo otsetsereka a 1/1000. Kuyesa kuthamanga kwa mpweya kwa 156.8N/cm2 kuyenera kuchitika evaporator isanayikidwe. Pakati pa evaporator kapena madzi ozizira ndi maziko othirira ndi pamwamba pa maziko, payenera kuwonjezeredwa matabwa olimba okwana 50-100mm, ndipo phula liyenera kuphimbidwa kuti lisawonongeke. Malo osungira ozizira ang'onoang'ono a tonnage sangakhale ndi malo owongolera madzi, ndipo madziwo amaperekedwa mwachindunji ndi malo osungira madzi. Ngati tonnage ya malo osungira ozizira ndi yayikulu, nyumba yosungiramo zinthu imakhala ndi zipinda zingapo zozizira, ndipo chipinda chilichonse chozizira chili ndi evaporator kapena chitoliro choziziritsira, malo osungira madzi ayenera kukhazikitsidwa. Madziwo amaperekedwa ku evaporator iliyonse kapena chitoliro choziziritsira kudzera mu valavu ya throttle.
5. Njira zolumikizira mapaipi nthawi zambiri zimaphatikizapo kuwotcherera, kulumikizana ndi ulusi ndi kulumikizana ndi flange. Kuwotcherera kuyenera kugwiritsidwa ntchito momwe kungathekere, kupatulapo komwe kulumikizana ndi ulusi kapena kulumikizana ndi flange kuyenera kugwiritsidwa ntchito poyika ndi kukonza. Pa kulumikizana ndi ulusi, mafuta a lead kapena tepi yotsekera ya PTFE iyenera kugwiritsidwa ntchito pa ulusi. Pa kulumikizana ndi flange, kuyimitsa kozungulira ndi kopingasa kuyenera kupangidwa pamwamba pa flange, ndipo makulidwe a 1 ~ 3mm ayenera kuwonjezedwa pa kuyimitsa, ndipo mafuta a lead ayenera kuphimbidwa mbali zonse ziwiri. Mpando wa rabara wa asbestos wopanikizika wapakati.
6. Malo otsetsereka a chitoliro: gawo lopingasa la chitoliro cha mafuta mu chitoliro chotulutsa utsi cha compressor yoziziritsa limapendekeka ndi 0.3% ~ 0.5% kulowera kwa cholekanitsa mafuta; gawo lochokera ku cholekanitsa mafuta kupita ku chitoliro choziziritsa limapendekeka ndi 0.3% ~ 0.5% kulowera kwa condenser; chotulutsira condenser Gawo lopingasa kuchokera ku chitoliro chamadzimadzi kupita ku chosungira champhamvu limapendekeka ndi 0.5% ~ 1.0% kulowera kwa chosungira champhamvu; gawo lopingasa la chitoliro kuchokera ku siteshoni yoziziritsira madzi kupita ku chitoliro choziziritsira limapendekeka ndi 0.1% ~ 0.3% kulowera kwa chitoliro choziziritsira; chitoliro choziziritsira kupita ku gasi Gawo lopingasa la chitoliro champhamvu limapendekeka ndi 0.1% ~ 0.3% kulowera kwa chitoliro choziziritsira utsi; gawo lopingasa la chitoliro cha Freon limapendekeka ndi 0.19 ~ 0.3% kulowera kwa chosungira champhamvu choziziritsira.
7. Pa kupindika kwa chitoliro, pamene m'mimba mwake wa chitoliro uli pansi pa Ф57, utali wa kupindika kwa chitoliro suli wochepera katatu kuposa m'mimba mwake wakunja wa chitoliro; pamene m'mimba mwake wa chitoliro uli pamwamba pa Ф57, utali wa kupindika kwa chitoliro suli wochepera katatu kuposa m'mimba mwake wakunja wa chitoliro. Kulumikizana kwa chitoliro kuyenera kuganizira kukula ndi kupindika kwa kutentha kwa chitoliro. Chifukwa chake, pamene chitoliro chotsika mphamvu chikuposa 100m ndipo chitoliro chokwera mphamvu chikuposa 50m, chigongono cha telescopic chiyenera kuwonjezeredwa pamalo oyenera a chitolirocho.
8. Mpando wothandizira chitoliro cha pakhoma uyenera kutenthedwa ndi matabwa a adiabatic, chitoliro cha pakhoma chiyenera kukhala kutali ndi khoma pa mtunda woposa 150mm, ndipo chitoliro cha padenga chiyenera kukhala kutali ndi denga pa mtunda woposa 300mm.
