1. I-thermostat yangaphakathi (ifakwe ngaphakathi kwi-compressor)
Ukuze kuthintelwe ukuba i-chiller epholiswe ngumoya ingaqhubeki isebenza iiyure ezingama-24, nto leyo ebangela ukuba i-compressor isebenze xa umthwalo uphezulu, i-electromagnetic switch imbi, i-shaft ibambekile, njl.njl., okanye i-motor itshiswe ngenxa yobushushu be-motor. I-compressor ixhotyiswe nge-thermostat yangaphakathi. Ifakwe kunxibelelwano olungathathi cala lwe-motor yesigaba sesithathu. Xa kwenzeka into engaqhelekanga, i-motor ikhuselwe ngokunqumla izigaba ezintathu ngaxeshanye.
2. Utshintsho lwe-electromagnetic
Iswitshi ye-electromagnetic sisixhobo sokuvula nokuvala esikufutshane ngenjongo yokulawula ukusebenza kunye nokumisa i-compressor yefriji ye-chiller epholileyo emoyeni. Ifanele igcinwe ithe nkqo ngexesha lokufakwa. Ukuba ifakwe ngokuchanekileyo, uxinzelelo lwentwasahlobo ye-node luya kutshintsha, ingxolo iya kuvela, kwaye kuya kwenzeka ilahleko yesigaba. Kwiimodeli ze-compressors ezixhotyiswe nge-power-off protectors ngqo, akukho mfuneko yokulayisha i-protectors.
3. Umkhuseli wesigaba esibuyela umva
Ii-scroll compressors kunye nee-piston compressors zinezakhiwo ezahlukeneyo kwaye azinakuguqulwa. Xa umbane wesigaba sesithathu se-air-cooled chiller uguqulwa, i-compressor iya kuguqulwa, ngoko ke kufuneka kufakwe i-reverse phase protector ukuthintela i-refrigeration compressor ukuba ingajiki. Emva kokuba i-reverse phase protector ifakiwe, i-compressor ingasebenza kwisigaba esihle kwaye ayizukusebenza kwisigaba esihle. Xa i-reverse phase isenzeka, tshintsha nje iingcingo ezimbini zombane ukuze utshintshele kwisigaba esihle.
4. Isikhuselo sobushushu bomphunga
Ukuze kukhuselwe i-compressor xa iphantsi komthwalo omkhulu okanye i-refrigerant enganeleyo, kufuneka kufakwe i-exhaust temperature protector kwinkqubo ye-cooled air chiller. Ubushushu be-exhaust bubekwe kwi-130℃ ukuze kumiswe i-compressor. Eli xabiso lobushushu libhekisa kumbhobho we-compressor exhaust ophuma kwindawo yokuphuma.
5. Utshintsho oluphantsi koxinzelelo
Ukuze kukhuselwe i-compressor ye-chiller epholileyo emoyeni ukuba ingasebenzi xa i-refrigerant inganelanga, kufuneka iswitshi enoxinzelelo oluphantsi. Xa ibekwe ngaphezulu kwe-0.03mpa, i-compressor iyeka ukusebenza. Nje ukuba i-compressor isebenze kwimeko ye-refrigerant enganelisiyo, ubushushu benxalenye ye-compressor kunye nenxalenye ye-motor buya kunyuka ngoko nangoko. Ngeli xesha, iswitshi enoxinzelelo oluphantsi inokukhusela i-compressor kumonakalo kunye nokutsha kwe-motor okungenakukhuselwa yi-thermostat yangaphakathi kunye ne-exhaust temperature.
6. Iswitshi yoxinzelelo oluphezulu ingamisa icompressor xa uxinzelelo oluphezulu lunyuka ngokungaqhelekanga, kwaye uxinzelelo olusebenzayo lubekwe ngezantsi.
