Kondensa inoshanda nekupfuudza gasi nepachubhu refu (inowanzo kuunganidzwa mu solenoid), zvichiita kuti kupisa kurasike kumhepo yakapoteredza. Simbi dzakadai semhangura dzine simba guru rekupisa uye dzinowanzo shandiswa kutakura utsi. Kuti kondensa ishande zvakanaka, ma heat sinks ane hunhu hwakanaka hwekupisa anowanzo wedzerwa kumapaipi kuti awedzere nzvimbo yekudzima kupisa kuti kukurumidze kupera kupisa, uye anoshandisa mafeni kuti akurumidze kutenderera kwemhepo kuti abvise kupisa.
Kuti titaure nezvepfungwa yekondensa, tanga tanzwisisa pfungwa yekondensa. Munguva yekudiridza, mudziyo unoshandura utsi kuita mamiriro emvura unonzi kondensa.
Pfungwa yekutonhodza inoshandiswa nemakondensa mazhinji: basa rekondensa rekondensa nderekudzvanya utsi hwemhepo hwakaderera kuita utsi hwemhepo hwakaderera, kuitira kuti huwandu hwemhepo huderere uye kumanikidzwa kuwedzere. Kondensa rekondensa rinofema utsi hwemvura hunoshanda hwakaderera hunobva mu evaporator, rokwidza kumanikidzwa, uye rotumira ku kondensa. Rinosanganiswa kuita mvura ine kumanikidzwa kwakakwira mu kondensa. Mushure mekudhonzwa ne throttle valve, rinova mvura inonzwa kumanikidzwa. Mushure mekunge mvura yaderera, rinotumirwa ku evaporator, uko rinotora kupisa uye rinopera kuti rive utsi ne kumanikidzwa kwakaderera, nokudaro richipedzisa kutenderera kwekondensa.
1. Nheyo huru dzehurongwa hwefiriji
Mushure mekunge mvura inotonhorera yatora kupisa kwechinhu chiri kutonhodzwa mu evaporator, inopfava kuita steam ine tembiricha yakaderera uye ine pressure yakaderera, iyo inosvetwa mu compressor yekufiriji, yomanikidzwa kuita steam ine pressure yakawanda uye ine temperature yepamusoro, yozoburitswa mu condenser. Mu condenser, inopihwa kunzvimbo inotonhorera (mvura kana Air) inoburitsa kupisa, inopfava kuita mvura ine pressure yakawanda, inodhonzwa kuita soft refrigerant ine pressure yakaderera uye ine temperature yakaderera ne throttle valve, yozopinda mu evaporator zvakare kuti itore kupisa uye ipfave, zvichizadzisa chinangwa chekufirijisa cycle. Nenzira iyi, refrigerant inopedzisa cycle yekufiriji kuburikidza nemaitiro mana ekutanga ekupfava, kudzvanya, kupfava, uye kupwanya mu system.
Musystem yekutonhodza, evaporator, condenser, compressor uye throttle valve ndizvo zvikamu zvina zvakakosha zvesystem yekutonhodza. Pakati pazvo, evaporator mudziyo unotakura simba rinotonhora. Refrigerant inotora kupisa kubva pachinhu chiri kutonhodzwa kuti iite firiji. Compressor moyo uye inoita basa rekusveta, kudzvanya, uye kutakura utsi hwe refrigerant. Condenser mudziyo unoburitsa kupisa. Unotamisa kupisa kunonyudzwa mu evaporator pamwe chete nekupisa kunoshandurwa necompressor kuenda kunzvimbo inotonhodza. Throttle valve inokanda nekudzikamisa refrigerant, inodzora uye inotonga huwandu hwemvura ye refrigerant inoyerera mu evaporator, uye inokamura system kuita zvikamu zviviri, divi re high-pressure ne side-low-pressure. Musystem chaiyo yekutonhodza, kuwedzera kune zvikamu zvina zvikuru zviri pamusoro apa, kazhinji kune mimwe michina yekubatsira, senge solenoid valves, distributors, dryers, collectors, fusible plugs, pressure controllers nezvimwe zvikamu, zvinoshandiswa kuvandudza mashandiro. Inodhura, yakavimbika uye yakachengeteka.
2. Nheyo yekudziya kwemhepo inodzvinyirira
Sisitimu yekutonhodza ine vapor compression ine danho rimwe chete ine zvikamu zvina zvikuru: compressor yekutonhodza, condenser, evaporator uye throttle valve. Zvakabatana nemapaipi kuti zvigadzire sisitimu yakavharwa. Refrigerant inoramba ichitenderera musisitimu, ichichinja mamiriro, uye ichichinjana kupisa nenyika yekunze.
3. Zvikamu zvikuru zvehurongwa hwefiriji
Zvikamu zvefiriji zvinogona kukamurwa kuita mhando mbiri zvichienderana nechimiro chekunyorovesa: zvikamu zvefiriji zvinotonhodzwa nemvura uye zvikamu zvefiriji zvinotonhodzwa nemhepo. Zvichienderana nechinangwa chekushandisa, zvinogona kukamurwa kuita mhando mbiri: chimwe chete chinotonhodza uye chimwe chinotonhodza nerudzi rwekupisa. Hazvina mhosva kuti nderupi rudzi rwakagadzirwa, runoumbwa nezvinotevera. Runoumbwa nezvikamu zvikuru.
Kondensa mudziyo unoburitsa kupisa. Unotamisa kupisa kunonyudzwa mu evaporator pamwe chete nekupisa kunoshandurwa ne compressor kuita chinhu chinotonhodza. Vharuvhu ye throttle inodzikisa kumanikidzwa kwe refrigerant, uye panguva imwe chete inodzora nekudzora huwandu hwemvura inotonhorera inoyerera mu evaporator, uye inokamura sisitimu kuita zvikamu zviviri, divi rine kumanikidzwa kwakanyanya uye divi rine kumanikidzwa kwakaderera.
