Ibikoresho byo muri firigo (compressor unit) bishyirwa mu cyumba cy'imashini, kandi ibidukikije biyikikije bigomba kubungabungwa:
1. Hagomba kubaho umwanya usobanutse wa metero 1.5 mu cyerekezo cy'uburebure bwa kompreseri ikora ubukonje, umwanya usobanutse wa metero 0.6 ~ 1.5 imbere n'inyuma, n'umwanya usobanutse wa metero 0.6 ku mpera imwe ugana ku rukuta mu cyerekezo cy'ibumoso n'iburyo, na metero 0.6 ku rundi ruhande. Umwanya usobanutse wa metero 0.9 ~ 1.2.
2. Ubushyuhe bw'ikirere ntibugomba kuba munsi ya dogere 10°C.
3. Iyo igikoresho gishyizwe hanze, hagomba kubaho ibikoresho birinda umuyaga, imvura n'izuba, kandi hagafatwa ingamba zo gukumira ingese no kwemeza ko amashanyarazi akingira. Kigomba gutandukanywa n'ibishyuhe byinshi, ibikoresho bishobora gushya n'ibiturika cyangwa ibikoresho biturika.
4. Imashini igomba kuba idashyuha kandi idakoresha amajwi.
Ibisabwa mu kubaka ibikoresho byo muri firigo:
1. Ifatizo ry'ibikoresho bikonjesha (compressor unit) rigomba kuba rifite imbaraga zihagije, kandi ifatizo rya beto rigomba kuba riri munsi y'ubutaka. Ubusanzwe uburemere bw'ibanze buruta uburemere bw'ifatizo rya compressor inshuro 2 kugeza kuri 5. Ku bikoresho bito n'ibiciriritse, compressor na moteri bikonjesha bishobora gushyirwa ku cyuma gihuriweho, hanyuma bigashyirwa ku rufatiro.
2. Ibikoresho byo gukonjesha (compressor unit) bigomba gushyirwaho mu buryo butambitse, kandi udupapuro tw’ubugari n’utumeze nk’udupira dufite ubuziranenge butari munsi ya 0.02 ~ 0.05 mm / m dushobora gukoreshwa mu gukosora ubugari. Kugira ngo bigabanye ukugurumana n’urusaku, ibikoresho bikurura ubugari, nk’udupapuro tw’ubugari, amasoko, n’ibindi, bigomba gushyirwaho hagati y’imashini n’ishingiro.
3. Umukandara wa compressor ikora ibyuma bikonjesha ugororotse kandi ujyanye n'umuyoboro w'icyuma cya moteri, kandi ubukana bw'umukandara bugomba kuba bukwiye. Uburyo bwo kugenzura ni ugukanda hagati y'umukandara n'intoki, kandi umukandara uri hagati ya mm 100 z'uburebure kandi uzunguruka nka mm 1 urakwiriye.
4. Ikizamini cy'umuvuduko w'umwuka cya 176.4N/cm2 kirakenewe kugira ngo hashyirweho condenser. Umuyoboro w'amazi usohoka muri condenser ugomba kuba werekeza kuri accumulator, ufite ubuhaname bwa 1/1000. Ikizamini cy'umuvuduko w'umwuka cya 156.8N/cm2 kigomba gukorwa mbere yuko evaporator ishyirwaho. Hagati y'imashini ishyushya cyangwa aho gukonjesha amazi n'aho kuhira n'ubuso bw'ifatizo, hagomba kongerwaho agapapuro k'ibiti gafite ubugari bwa mm 50-100, kandi hagashyirwamo kaburimbo kugira ngo harwanye ingese. Ububiko buto bukonje bushobora kuba budafite aho bugenzura amazi, kandi amazi atangwa mu buryo butaziguye n'aho abikwa. Niba toni y'aho abikwa ari nini, ububiko bugizwe n'ibyumba byinshi bikonje, kandi buri cyumba gikonje gifite evaporator cyangwa umuyoboro ushyushya amazi, hagomba gushyirwaho ahantu ho gukonjesha amazi. Amazi atangwa kuri buri evaporator cyangwa umuyoboro ushyushya amazi binyuze muri valve.
5. Uburyo bwo guhuza imiyoboro muri rusange burimo gusudira, guhuza imigozi no guhuza flange. Gusudira bigomba gukoreshwa uko bishoboka kose, keretse aho guhuza imigozi cyangwa flange bigomba gukoreshwa mu gushyiraho no kubungabunga. Ku guhuza imigozi, amavuta y'icyuma cyangwa kaseti yo gufunga ya PTFE bigomba gushyirwa ku mugozi. Ku guhuza imigozi, hagomba gukorwa icyuma gifunganye n'igifunganye ku buso bw'icyuma gifunganye, kandi hagashyirwaho ubugari bwa mm 1 ~ 3 ku gice gifunganye, kandi amavuta y'icyuma agomba gusigwa ku mpande zombi. Umupira wa asbestos ufite umuvuduko uringaniye.
6. Uburyo bwo gushyiraho imiyoboro: igice cy'umuyoboro utambitse w'icyuma gitandukanya amavuta mu muyoboro usohora umwuka wa compressor ishyushya giteganye na 0.3% ~ 0.5% ku cyerekezo cy'icyuma gitandukanya amavuta; igice kiva ku gitandukanya amavuta kijya ku muyoboro ushyushya giteganye na 0.3% ~ 0.5% ku cyerekezo cy'icyuma gishyushya; aho icyuma gisohokera. Igice kitambitse kiva ku muyoboro w'amazi kijya ku cyuma gishyushya umwuka giteganye na 0.5% ~ 1.0% ku cyerekezo cy'icyuma gishyushya umwuka giteganye na 0.1% ~ 0.3% ku cyerekezo cy'icyuma gishyushya umwuka giteganye na 0.1% ~ 0.3% ku cyerekezo cy'icyuma gishyushya umwuka gifatanye na gazi. Igice cy'umuyoboro utambitse w'icyuma gishyushya umwuka giteganye na 0.1% ~ 0.3% ku cyerekezo cy'umuyoboro ushyushya umwuka ufatanye na gazi.
7. Ku bijyanye no kugonda umuyoboro, iyo umurambararo w'umuyoboro uri munsi ya Ф57, umurambararo w'umuyoboro ntuba munsi y'inshuro 3 z'umurambararo w'inyuma w'umuyoboro; iyo umurambararo w'umuyoboro uri hejuru ya Ф57, umurambararo w'umuyoboro ntuba munsi y'inshuro 3.5 z'umurambararo w'inyuma w'umuyoboro. Guhuza umuyoboro bigomba kwita ku kwaguka n'igabanuka ry'ubushyuhe bw'umuyoboro. Kubwibyo, iyo umuyoboro ufite umuvuduko muto urenze metero 100 n'umuyoboro ufite umuvuduko mwinshi urenze metero 50, inkokora ya teleskopu igomba kongerwaho aho umuyoboro uherereye.
8. Intebe y'icyuma gishyigikira umuyoboro w'urukuta igomba gushyushywa n'igiti cy'igiti cya adiabatic, umuyoboro w'urukuta ugomba kuba kure ya mm zirenga 150 uvuye ku rukuta, naho umuyoboro wo hejuru ukagomba kuba kure ya mm zirenga 300 uvuye ku gisenge.
