Kana tembiricha yekudziya kwemuchina wekuchengetera zvinhu zvinotonhora yaderera kupfuura 0 ° C, chando chinobuda pamusoro pemuchina wekudziya, zvichikanganisa mashandiro ekupisa. Saka, kunyungudutsa nguva dzose chikamu chakakosha chekuchengetedza muchina wekuchengetera zvinhu zvinotonhora. Kune nzira dzakawanda dzekunyungudutsa. Parizvino, vagadziri vekuvaka muchina wekuchengetera zvinhu zvinotonhora vanoshandisa nzira shanu: kunyungudutsa kwekugadzira, kunyungudutsa nemagetsi, kunyungudutsa nemhepo inopisa, kunyungudutsa nechando mumvura inopisa.
1. Kunyungudutsa nemaoko kunoreva kubvisa nemaoko chando chiri pamusoro pechubhu yekuburitsa evaporator. Nzira iyi inogona kuitwa pasina kumisa michina yekutonhodza. Nzira iyi inotora nguva uye inonetsa, uye kunyungudutsa kwacho hakuna kunaka.
2. Kunyungudutsa nemagetsi kunoreva kuisa hita yemagetsi pa evaporator kuti inyunguduke nemagetsi. Panguva yekunyungudutsa, misa compressor kana kurega kupa mvura ku evaporator. Kunyungudutsa nemagetsi kune zvakanakira zvemutengo wakaderera uye nyore kudzora, asi mutengo wekushanda wakakwira. Kazhinji inoshandiswa pakunyungudutsa michina yekuchengetera inotonhora, kwete pakunyungudutsa michina yekufiriji. Kune tembiricha dzakasiyana, zvinodiwa zvehunyanzvi hwekuputira zvinofanirwa kunge zvakasiyana, uye kugona kutonhora kunodiwa kunofanirwawo kunge kwakasiyana. Kugadzwa kwenzvimbo yekuchengetera inotonhora kunofanirwa kugadziriswa zvichienderana nenzvimbo chaiyo yekushandisa kwemutengi uye mashandisirwo ayo, kunze kwekunge pasina chikonzero chakakosha chekutevera nzira yekumisikidza.
3. Kunyungudutsa gasi rinopisa kunoshandiswa kwemhepo inopisa inotonhorera inoburitswa necompressor kuburitsa kupisa mu evaporator nekunyungudutsa chando chiri pamusoro pe evaporator. Sisitimu yekunyungudutsa gasi rinopisa yakaoma uye mutengo wakakwira. Asi mhedzisiro yekunyungudutsa iri nani. Kana ikashandiswa mu ammonia system, mafuta anounganidzwa mu evaporator anogonawo kuburitswa mu drain kana mudura rekutenderera kwemhepo rakaderera. Mukuita kwekunyungudutsa gasi rinopisa, kudzvanywa kunowanzo dzorwa pa 0.6MPa. Edza kushandisa gasi rine pressure yakakwira rinoburitswa kubva mu single stage compressor kuti unyungudise. Nguva yechando inogona kukodzera kuderedza mvura inotonhorera kana kuderedza huwandu hwe condenser, kuwedzera tembiricha yekubuda, kupfupisa nguva yekunyungudutsa. Kune masisitimu e ammonia, ammonia inopisa yekunyungudutsa inofanira kubatanidzwa ne exhaust pipe ye oil separator.
4. Kunyungudutsa mvura kunoreva kupfapfaidza mvura pamusoro pe evaporator nemudziyo wekupfapfaidza kuti inyungudise chando. Sisitimu yekunyungudutsa mvura ine chimiro chakaoma uye inodhura zvakanyanya, asi ine mhedzisiro yakanaka uye inodhura zvishoma. Kunyungudutsa mvura kunogona chete kubvisa chando pamusoro pe evaporator, uye hakugone kugadzirisa mhedzisiro yakaipa yekuunganidzwa kwemafuta mu evaporator pakupisa. Chinhu chakakosha ibhodhi rekuchengetera mvura inotonhora, iro rinowanzo gadzirwa pachine nguva nemugadziri webhodhi rekuchengetera mvura inotonhora uye rine urefu hwakatarwa, upamhi uye ukobvu hwakatarwa. Bhodhi rekuchengetera mvura inotonhora rine ukobvu hwe100mm rinowanzo shandiswa pakuchengetedza mvura inotonhora pakupisa kwepamusoro nepakati, bhodhi rekuchengetera mvura inotonhora rine ukobvu hwe120mm kana 150mm rinowanzo shandiswa pakuchengetedza mvura inotonhora pakupisa kwakaderera uye pakupisa nechando.
5. Kunyungudutsa mvura inopisa mumhepo ndiyo nzira mbiri dzekunyungudutsa mvura inopisa nekudzingudutsa mvura dzinoshandiswa panguva imwe chete, dzinonyanya kukoshesa zvakanakira zvese izvi, uye dzinogona kubvisa nekukurumidza uye zvinobudirira chando chiri pamusoro pe evaporator uye kubvisa kuungana kwemafuta mukati me evaporator. Pakunyungudutsa, gasi rinopisa rinotanga ratumirwa mu evaporator kuti riparadzanise chando chiri pamusoro pe evaporator, uye mvura inopfapfaidzwa kuti isuke chando chiri pamusoro. Mushure mekunge mvura yabviswa, pamusoro pe evaporator "panoomeswa" nemhepo inopisa kudzivirira firimu remvura pamusoro kuti rirege kuomeswa nechando uye kukanganisa kutamiswa kwekupisa. Kare, vagadziri vemabhodhi ekuchengetera mvura inotonhora vaishandisa polyethylene ne polystyrene sezvinhu. Iye zvino kune kushanda kuri nani kwe polyurethane sandwich board. Polystyrene foam insulation material density yakaderera, haigone kunyungudutswa. Inowanzo shandiswa mumidziyo yakakosha. Polyethylene chinhu chakanaka. Kuburikidza nechiyero chakati, inogona kupurwa furo kubva muhuwandu hwakakodzera, insulation effect yakanaka, simba rakasimba rekutakura rezvinhu zvekunyungudutsa. Purati yepolyurethane iri nani, ine basa rekudzivirira kupisa riri nani uye haitore hunyoro, asi mutengo uyu wekuchengetedza unotonhora wakakwira zvishoma.
