E like me ka mea i hōʻike ʻia ma ke Kiʻi 1, hiki iā ʻoe ke ʻike i ke kiʻi o kahi pahu hau home 185 lita i hoʻohana ʻia no ke aʻo ʻana.Aia i loko o ka evaporator, ka hermetic reciprocating compressor a me ka ea-cooled condenser.Hoʻokomo ʻia nā ana kaomi ʻehā ma ke komo komo ʻana o ka compressor, condenser inlet a me ka puka evaporator.No ka pale ʻana i ka haʻalulu i ka wā o ka hoʻāʻo ʻana, ua kau ʻia kēia mau mika.No ka heluhelu ʻana i ka mahana thermocouple, hoʻopili ʻia nā uea thermocouple a pau i kahi scanner thermocouple.Hoʻokomo ʻia nā mea ana wela he ʻumi ma ka evaporator inlet, compressor suction, compressor discharge, refrigerator compartment and inlet, condenser inlet, freezer compartment and condenser outlet.Hōʻike pū ʻia ka volta a me ka hoʻohana ʻana i kēia manawa.Hoʻopaʻa ʻia kahi mīkini kahe e pili ana i kahi ʻāpana paipu ma kahi papa lāʻau.Mālama ʻia nā hoʻopaʻa ʻana i kēlā me kēia 10 kekona me ka hoʻohana ʻana i ka hui Human Machine Interface (HMI).Hoʻohana ʻia ke aniani ʻike e nānā i ke kūlike o ka kahe condensate.
Ua hoʻohana ʻia kahi ammeter Selec MFM384 me ka volta hoʻokomo o 100-500 V e helu i ka mana a me ka ikehu.Hoʻokomo ʻia kahi awa lawelawe ʻōnaehana ma luna o ka compressor no ka hoʻouka ʻana a me ka hoʻouka hou ʻana i ka refrigerant.ʻO ka hana mua e hoʻokahe i ka wai mai ka ʻōnaehana ma o ke awa lawelawe.No ka wehe ʻana i nā mea ʻino mai ka ʻōnaehana, holoi me ka nitrogen.Hoʻopiʻi ʻia ka ʻōnaehana me ka hoʻohana ʻana i kahi ʻōpala, kahi e hoʻokuʻu ai i ka ʻāpana i kahi kaomi o -30 mmHg.Hōʻike ka Papa 1 i nā hiʻohiʻona o ka pahu hoʻāʻo ʻana o ka pahu hau home, a ʻo ka Papa 2 ka papa inoa o nā waiwai i ana ʻia, a me ko lākou laulā a me ka pololei.
Hōʻike ʻia nā hiʻohiʻona o nā mea hoʻoheheʻe i hoʻohana ʻia i loko o nā pahu hau a me nā pahu hau hau ma ka Papa 3.
Ua mālama ʻia ka hoʻāʻo ʻana e like me nā ʻōlelo aʻoaʻo o ka ASHRAE Handbook 2010 ma lalo o kēia mau kūlana:
Eia kekahi, inā pono, ua hana ʻia nā mākaʻikaʻi e hōʻoia i ka reproducibility o nā hopena.ʻOiai ke kūpaʻa mau nei nā kūlana hana, hoʻopaʻa ʻia ka mahana, ke kaomi, ke kahe o ka refrigerant a me ka hoʻohana ʻana i ka ikehu.Ana ʻia ka mahana, ke kaomi, ka ikehu, ka mana a me ke kahe e hoʻoholo ai i ka hana ʻōnaehana.E ʻimi i ka hopena hoʻoluʻu a me ka maikaʻi no ke kahe nuipa a me ka mana ma kahi mahana i hāʻawi ʻia.
Ke hoʻohana nei i ka CFD e kālailai i ke kahe ʻelua ʻāpana i loko o kahi ʻōwili spiral friji home, hiki ke helu maʻalahi ka hopena o ka lōʻihi capillary.Maʻalahi ka nānā ʻana i ka CFD i ka neʻe ʻana o nā ʻāpana wai.Ua kālailai ʻia ka mea hoʻoheheʻe e hele ana i loko o ka ʻōwili spiral me ka polokalamu CFD FLUENT.Hōʻike ka papa 4 i nā ana o nā coils capillary.
Na ka FLUENT software mesh simulator e hoʻohua i ke ʻano hoʻolālā hoʻolālā a me ka mesh (Nā Kiʻi 2, 3 a me 4 e hōʻike ana i ka mana ANSYS Fluent).Hoʻohana ʻia ka nui o ka wai o ka paipu no ka hana ʻana i ka mesh palena.ʻO kēia ka pahu i hoʻohana ʻia no kēia haʻawina.
Ua hoʻomohala ʻia ke kumu hoʻohālike CFD me ka hoʻohana ʻana i ka platform ANSYS FLUENT.ʻO ke ao holoʻokoʻa wai wale nō ka mea i hōʻike ʻia, no laila ua hoʻohālikelike ʻia ke kahe o kēlā me kēia capillary serpentine e like me ke anawaena o ka capillary.
Ua lawe ʻia ke kumu hoʻohālike GEOMETRY i ka polokalamu ANSYS MESH.Kākau ʻo ANSYS i ke code kahi i hui pū ai ʻo ANSYS i nā kumu hoʻohālike a me nā kūlana palena.Ma ka fig.Hōʻike ka 4 i ka hoʻohālike paipu-3 (3962.4 mm) ma ANSYS FLUENT.Hāʻawi nā mea Tetrahedral i ke kūlike kiʻekiʻe, e like me ka mea i hōʻike ʻia ma ka Figure 5. Ma hope o ka hana ʻana i ka mesh nui, mālama ʻia ka faila ma ke ʻano he mesh.Ua kapa ʻia ka ʻaoʻao o ka pōʻai ʻo ka inlet, ʻoiai ʻo ka ʻaoʻao e kū pono ana i ka puka.Mālama ʻia kēia mau maka poepoe e like me nā paia o ka paipu.Hoʻohana ʻia ka media wai e kūkulu i nā hiʻohiʻona.
ʻO ka manaʻo o ka mea hoʻohana e pili ana i ke kaomi, ua koho ʻia ka hopena a ua koho ʻia ke koho 3D.Ua ho'ā 'ia ke kumu hana mana.
Ke manaʻo ʻia ke kahe ʻana he chaotic, ʻaʻohe laina laina.No laila, ua koho ʻia ke kahe K-epsilon.
Inā koho ʻia kahi mea ʻē aʻe i kuhikuhi ʻia e ka mea hoʻohana, ʻo ke kaiapuni: wehewehe i nā waiwai thermodynamic o R152a refrigerant.Mālama ʻia nā ʻano ʻano ma ke ʻano he waihona waihona.
ʻAʻole hoʻololi nā kūlana lewa.Ua hoʻoholo ʻia kahi wikiwiki inlet, ua wehewehe ʻia kahi kaomi o 12.5 bar a me kahi mahana o 45 °C.
ʻO ka hope, ma ka ʻumikūmālima hoʻomaʻamaʻa, hoʻāʻo ʻia ka hoʻonā a hoʻohuli ʻia i ka ʻumikūmālima hou, e like me ka hōʻike ʻana ma ke Kiʻi 7.
He ala ia o ka palapala ʻāina a me ke kālailai ʻana i nā hopena.Plot pressure a me ka wela ikepili puka lou me ka Monitor.Ma hope o kēlā, hoʻoholo ʻia ka nui o ke kaomi a me ka mahana a me nā ʻāpana wela maʻamau.Hōʻike kēia ʻikepili i ka nui o ka hāʻule ʻana o ke kaomi ma waena o nā wili (1, 2 a me 3) ma nā helu 1 a me 2. 7, 8 a me 9.Ua lawe ʻia kēia mau hopena mai kahi papahana holo.
Ma ka fig.Hōʻike ka 10 i ka hoʻololi o ka pono no nā lōʻihi like ʻole o ka evaporation a me ka capillary.E like me ka mea i ʻike ʻia, piʻi ka maikaʻi me ka piʻi ʻana o ka mahana evaporation.Loaʻa ka hana kiʻekiʻe a me ka haʻahaʻa loa i ka hiki ʻana i ka capillary spans o 3.65 m a me 3.96 m.Inā hoʻonuiʻia ka lōʻihi o ka capillary e kekahi nui, e emi ana ka pono.
Hōʻike ʻia ka hoʻololi ʻana i ka mana hoʻomaha ma muli o nā pae like ʻole o ka mahana evaporation a me ka lōʻihi capillary ma ka fig.11. ʻO ka hopena capillary ke alakaʻi i ka emi ʻana o ka hiki ke hoʻomaha.Loaʻa ka mana hoʻoluʻu liʻiliʻi ma kahi wahi hoʻolapalapa o -16°C.ʻIke ʻia ka mana hoʻomaha nui loa i nā capillaries me ka lōʻihi o 3.65 m a me kahi mahana o -12°C.
