Ihe mejupụtara ya bụ akụkụ anọ: Compressor, condenser, throttling method and evaporator. A na-ejikọta ha n'aka site na ọkpọkọ iji mepụta usoro mechiri emechi.
Isi ihe nju oyi na ngwa
1.Compressor
A na-ekewa compressors ụzọ atọ: ụdị mepere emepe, ụdị ọkara mepere emepe na ụdị mechiri emechi. Ọrụ nke compressor bụ ịmịnye refrigerant nke dị ala site na akụkụ evaporator, wee pịnye ya n'ime ikuku ikuku na-ekpo ọkụ dị elu ma ziga ya na condenser.
2.Condenser
Condenser bụ ngwaọrụ mgbanwe okpomọkụ nke na-ebufe ikike refrigeration nke evaporator na usoro refrigeration ọnụ na mkpakọ egosi ọrụ nke compressor na gburugburu ebe obibi (mmiri oyi ma ọ bụ ikuku).

3. Evaporator
The evaporator pụtara na refrigerant mmiri esi na-amịkọrọ okpomọkụ nke jụrụ oyi (ikuku ma ọ bụ mmiri) na obere okpomọkụ iji nweta nzube nke refrigeration.
4. Solenoid valvụ
Solenoid valvụ bụ ụdị valvụ mechiri emechi nke a na-emeghe ozugbo n'okpuru njikwa eletriki. A na-etinyekarị ya na pipeline usoro ka ịgbanye na-akpaghị aka na-eme ka onye na-arụ ọrụ nke nhazi ọnọdụ abụọ nke pipeline refrigeration. A na-etinyekarị valvụ solenoid n'etiti valvụ mgbasawanye na condenser. Ebe ahụ kwesịrị ịdị nso dị ka o kwere mee na valvụ mgbasawanye, n'ihi na valvụ mgbasawanye bụ naanị ihe na-eme ka ọ bụrụ ihe na-eme ka ọ bụrụ ihe na-eme ka ọ ghara imechi ya n'onwe ya, ya mere, a ghaghị iji valvụ solenoid na-ebipụ pipeline mmiri mmiri.
5.Thermal mgbasa valvụ
Ngwa ngwa nju oyi na-ejikarị valvụ mgbasawanye ọkụ na-emezigharị ikuku refrigerate. Ọ bụghị naanị valvụ na-achịkwa na-achịkwa ihe na-enye mmiri mmiri nke evaporator, kamakwa valvụ trotul nke ngwaọrụ refrigeration. Valve mgbasawanye ọkụ na-eji mgbanwe dị na superheat nke refrigerant na mwepu nke evaporator iji dozie ọkọnọ mmiri. A na-ejikọta valvụ ịgbasa ọkụ ọkụ na ọkpọkọ ntinye mmiri mmiri nke evaporator, a na-etinyekwa bọlbụ na-ahụ maka okpomọkụ na ọkpọkọ evaporator (outlet). A na-ekewakarị ya n'ụdị dị iche iche dịka nhazi nke valvụ mgbasa ọkụ ọkụ:
(1) valvụ mgbasa ọkụ na-eme ka ọ dị mma n'ime;
(2) valvụ ịgbasa ọkụ na-agbanwe agbanwe na mpụga.
valvụ ịgbasa ọkụ na-eme ka ọ dị mma n'ime: Ọ mejupụtara bọlbụ mmetụta okpomọkụ, tube capillary, oche valvụ, diaphragm, mkpanaka ejector, agịga valve na usoro nhazi. A na-ejikarị valvụ mgbasa ọkụ na-ekpo ọkụ na-emeziwanye nke ọma n'ime obere ikuku.
valvụ Mgbasa ọkụ na-emeziwanye nke ọma na mpụga: valvụ Mgbasa ọkụ na-eme ka ọ dị mma maka ndị na-ekupụ ikuku nwere ogologo pipeline ma ọ bụ nguzogide ka ukwuu, a na-ejikarị valvụ ịgbasa ọkụ na-emezigharị na mpụga. Maka evaporator nke otu nha, enwere ike iji valvụ mgbasawanye n'ime ime eme ihe mgbe ejiri ya na nchekwa okpomọkụ dị elu, ebe enwere ike iji valvụ mgbasawanye nke mpụga mgbe ejiri ya na nchekwa dị ala. Maka evaporator nke otu nha, enwere ike iji valvụ mgbasawanye n'ime ime eme ihe mgbe ejiri ya na nchekwa okpomọkụ dị elu, ebe enwere ike iji valvụ mgbasawanye nke mpụga mgbe ejiri ya na nchekwa dị ala.
