Ụkpụrụ nju oyi nke okpukpu abụọ

Igwe nju oyi nke okpukpu abụọ na-ejikarị kọmpụta abụọ, ya bụ compressor dị ala na nke nwere oke nrụgide.

1.1 Usoro nke ikuku refrigerant na-abawanye site na nrụgide na-ekupụ na nrụgide condensing na-ekewa n'ime usoro abụọ.

Nkeji nke mbụ: Mpịakọta na nrụgide etiti site na kọmpụta nke obere nrụgide na mbụ:
Nkeji nke abụọ: gas dị n'okpuru nrụgide dị n'etiti na-agbanyekwu na nrụgide condensation site na nrụgide nrụgide dị elu mgbe ọ dị jụụ n'etiti, na ntụgharị ntụgharị na-emecha usoro refrigeration.

Mgbe ị na-emepụta okpomọkụ dị ala, onye na-eme ihe na-ekpo ọkụ nke okpukpu abụọ nke mkparịta ụka refrigeration na-ebelata okpomọkụ ntinye nke refrigerant na nrụgide ọkwa nrụgide dị elu, ma na-ebelata okpomọkụ nkwụsị nke otu compressor.

Ebe ọ bụ na okirikiri abụọ nke mkparịta ụka refrigeration nke abụọ na-ekewa usoro refrigeration dum na nkebi abụọ, ọnụ ọgụgụ mkpakọ nke ọkwa ọ bụla ga-adị nnọọ ala karịa nke mkpakọ otu nkeji, na-ebelata ihe ndị a chọrọ maka ike akụrụngwa ma na-emeziwanye arụmọrụ nke refrigeration okirikiri. A na-ekewa okirikiri nju oyi nke okpukpu abụọ n'ime usoro nju oyi zuru oke na usoro nju oyi na-ezughị ezu dịka ụzọ dị iche iche dị n'etiti; ọ bụrụ na ọ dabere na usoro ntugharị, enwere ike kewaa ya n'ime okirikiri nke mbụ na nke abụọ.

1.2 Ụdị refrigerant mkpakọ okpukpu abụọ

Ọtụtụ n'ime sistemụ nju oyi nke nkeji abụọ na-ahọrọ refrigerants nke ọkara na obere okpomọkụ. Nnyocha nnwale na-egosi na R448A na R455a bụ ezigbo nnọchi maka R404A n'ihe gbasara arụmọrụ ike. Tụnyere ihe ndị ọzọ na hydrofluorocarbons, CO2, dị ka mmiri na-arụ ọrụ enyi na gburugburu ebe obibi, bụ ihe nwere ike dochie anya hydrofluorocarbon refrigerants ma nwee ezigbo àgwà gburugburu ebe obibi.

Ma dochie R134a na CO2 ga-emebi usoro arụmọrụ, karịsịa na elu ambient okpomọkụ, nrụgide nke CO2 usoro bụ nnọọ elu na-achọ pụrụ iche ọgwụgwọ nke isi components, karịsịa compressor.

1.3 Nchọpụta kachasị mma na nju oyi nke nkeji abụọ

Ka ọ dị ugbu a, nsonaazụ nyocha kachasị mma nke sistemu igwe nju oyi nke nkeji abụọ bụ nke kachasị dị ka ndị a:
(1) Mgbe ị na-amụba ọnụ ọgụgụ nke ahịrị tube na intercooler, ibelata ọnụ ọgụgụ nke ahịrị tube na ikuku oyi nwere ike ịbawanye ebe mgbanwe okpomọkụ nke intercooler na-ebelata ikuku ikuku kpatara site na ọnụ ọgụgụ buru ibu nke ahịrị tube na ikuku oyi. N'ịlaghachi na ntinye ya, site na ndozi ndị a dị n'elu, enwere ike ibelata okpomọkụ ntinye nke intercooler site na ihe dịka 2 Celsius C, n'otu oge ahụ, enwere ike ijide n'aka mmetụta jụrụ oyi nke ikuku oyi.

(2) Debe ugboro ugboro nke obere nrụgide na-agbanwe agbanwe, ma gbanwee ugboro ugboro nke nrụgide nrụgide dị elu, si otú ahụ na-agbanwe nha nke nnyefe gas nke nnukwu nrụgide. Mgbe ikuku evaporation na-adịgide adịgide na -20 ° C, COP kacha elu bụ 3.374, na nke kachasị oke nnyefe gas kwekọrọ na COP bụ 1.819.

(3) Site n'ịtụle ọtụtụ CO2 transcritical transcritical abụọ usoro mkpakọ refrigeration usoro, ọ na-kwubiri na mpụta okpomọkụ nke gas ngwa nju oyi na arụmọrụ nke ala-nrụgide ogbo compressor nwere mmetụta dị ukwuu na okirikiri na a nyere nrụgide, ya mere, ọ bụrụ na ị chọrọ iji melite usoro arụmọrụ, ọ dị mkpa iji belata mpụta okpomọkụ nke gas-nju oyi na-arụ ọrụ ogbo efficiency.
