ʻO ka Compressor Air Conditioning Uila NF no ke kaʻa

ʻO kamīkini hoʻoluʻu ea uilaʻo ia ka ʻāpana koʻikoʻi o ka ʻōnaehana ea hoʻoluʻu o kahi kaʻa uila. ʻO kāna kumu hana e pili ana i ka hoʻohana ʻana i kahi motika uila e hoʻopili i kahi refrigerant kinoea haʻahaʻa haʻahaʻa i loko o kahi kinoea wela kiʻekiʻe, e hoʻoneʻe ana i ka refrigerant ma o kahi ʻōnaehana pani e hoʻokō ai i ka hoʻoluʻu (a i ʻole ka hoʻomehana ʻana) i loko o ke kaʻa.

Ma muli o kāna kaʻina hana koʻikoʻi, ua hahai ʻo ia i kahi pōʻaiapuni hoʻomaʻalili o "compression-condensation-expansion-evaporation":

1. Kaomi ʻana: Hoʻokele kahi motika uila i ka mīkini kaomi—ʻo ia hoʻi kahi ʻākoakoa ʻōwili a i ʻole piston reciprocating—e kaomi adiabatically i ka mahu refrigerant haʻahaʻa haʻahaʻa i huki ʻia mai ka evaporator. Hoʻokiʻekiʻe kēia kaʻina hana i ke kaomi o ka refrigerant a me ka mahana saturation, e hua mai ana i ka mahu superheated wela kiʻekiʻe.

2. Condensation: Hoʻouna ʻia ka mahu refrigerant wela kiʻekiʻe me ke kaomi kiʻekiʻe i ka condenser waho, kahi e hōʻole ai i ka wela latent i ka ea ambient ma o ka convection forced. ʻO ka hopena, hele ka refrigerant i ka desuperheating piha, condensation, a me ka subcooling, e puka ana ma ke ʻano he wai subcooled me ke kaomi kiʻekiʻe.

3. Hoʻonui: Hele ka refrigerant wai kiʻekiʻe-kaomi ma o kahi kiwikā hoʻonui thermostatic (TXV) a i ʻole ka kiwikā hoʻonui uila (EXV), e hana ana i kahi kaʻina hana throttling isenthalpic. Hoʻemi nui kēia i kona kaomi a me ka mahana, e hana ana i kahi hui wai-mahana haʻahaʻa, haʻahaʻa-kaomi (ʻo ka maʻamau he 20-30% ka maikaʻi o ka mahu).

4. Ka mahu ʻana: Komo ka hui ʻana o ka refrigerant haʻahaʻa haʻahaʻa i loko o ka evaporator i kau ʻia ma ke keʻena. Hoʻopili ia i ka wela sensible a me ka wela latent mai ke kahawai ea recirculated/ambient, e mahu piha ana i loko o ka mahu saturated a i ʻole ka mahu superheated iki. Hoʻomaʻalili a hoʻomaʻemaʻe kēia hoʻololi pae endothermic i ka ea i hāʻawi ʻia i ka keʻena o ka mea holo.

5. Kaʻapuni: ʻO ka mahu refrigerant haʻahaʻa haʻahaʻa haʻahaʻa i hoʻihoʻi ʻia i loko o ka puka komo compressor, a laila e hoʻopau ana i ke kaʻapuni thermodynamic loop pani—i hana hou ʻia e mālama i ka ʻoluʻolu wela o ke keʻena a me ke kūpaʻa o ka ʻōnaehana.
