Pehea e hoʻoholo ai inā pōʻino kahi condenser a i ʻole evaporator?

 

 

ʻO nā condensers a me nā evaporators nā ʻāpana hoʻololi wela nui o nā ʻōnaehana refrigeration, a ʻo kā lākou kūlana hana e pili pono i ka pono o ka refrigeration a me ka paʻa o ka ʻōnaehana. ʻO ka hoʻoholo ʻana inā ua pōʻino lākou e pono ai ka hoʻohui ʻana i nā nānā ʻike maka, ka nānā ʻana i nā parameter hana, ka loiloi hana, a me nā ʻano hoʻāʻo kōkua. Ma lalo iho nei nā ʻano hoʻoholo hoʻoholo kikoʻī:

1. Nānā Kiʻi

1.1 Condenser Visual Inspection

 

Poino kino: E nānā inā piʻo, ʻeʻe, a haki paha nā paipu keleawe a me ke kila ʻole o ka condenser. No nā condensers hoʻoheheʻe ʻia e ka ea, ʻo ka nui -nui i hāʻule a i ʻole nā ​​haʻi hope e hoʻemi i ka holo ʻana o ka ea a hoʻohaʻahaʻa loa i ka pono hoʻololi wela. No ka wai-condensers hoʻoheheʻe ʻia, e nānā i ka pūpū no nā māwae a i ʻole nā ​​kahe wili; ʻO nā ʻili wai, ka ʻōpala, a i ʻole nā ​​​​mea ʻaila refrigerant e hōʻike i ka nui o ka leakage.

ʻO ka hoʻoulu ʻana: ʻO kahi papa mānoanoa o ka lepo, ka aila, a i ʻole ka unahi (i loko o ka wai-hui hoʻoluʻu) ma ka ʻili condenser e hana ʻia ma ke ʻano he mea hoʻokaʻawale, e hoʻemi ʻole i ka wela. Ma lalo o nā kūlana maʻamau, pono e maʻemaʻe kaʻili; hiki ke ho'āla i nā hewa o ka hana -ʻoi aku ma luna o 0.5mm mānoanoa (ʻoiai me ka ʻole o ka pōʻino).

ʻO ka ʻinoʻino: Ma ke kahakai a i ʻole ke kiʻekiʻe -māmā, hiki i nā paipu condenser ke ʻinoʻino. ʻO nā paia paipu lahilahi a i ʻole ka lua ʻana a i ʻole ka puka ʻana e hoʻoheheʻe ʻia ka mea hoʻoheheʻe, e hōʻino nui ana.

1.2 Nānā Kiʻi Evaporator

 

ʻO ka hau hau ʻole: Pono e loaʻa i kahi evaporator maʻamau ka hau lahilahi. ʻO ka hau mānoanoa kūloko a i ʻole ka hau like ʻole (e laʻa, ka hau nui ma ka puka komo, ʻaʻohe hau ma ka puka waho) hiki ke hōʻike i ka paʻa ʻana o ka paipu, lawa ʻole ka pahu hau, a i ʻole nā ​​kahe o loko. No ka loaʻa ʻole o ka hau, pono ke nānā ʻana i nā leaka a i ʻole nā ​​haki paipu.

Leak traces: ʻO nā kaha ʻaila ma ka ʻili o ka evaporator (hui pū ka mea hoʻoheheʻe me ka ʻaila refrigeration a me nā lei me ia), ʻoi aku ka nui ma nā hui paipu a me nā welds, nā hōʻailona maʻamau o ka leakage. No nā mea hoʻoheheʻe i kūkulu ʻia i loko o ka -evaporators, e nānā inā ua pulu ka insulation; ʻO ka poʻi a i ʻole ka hū ʻana o ka wai i loko o ka insulation hiki ke hele pū me ka perforation evaporator.

Poino kino: ʻO nā paipu evaporator he mānoanoa-nā niho, nā māwae i ka hopena, a i ʻole nā ​​paipu hoʻololi wela o loko e hoʻopau pololei i ka hiki ke hoʻololi wela.

2. Ka nānā ʻana i ka ʻāpana hana

2.1 Hoʻohālikelike Kūlana Mahana

 

Condenser: I ka hana ma'amau, he 8–12 degere ka 'oko'a wela o ka ea -puka puka no na condensers i ho'olu'u i ka ea, a he 4-6 degere ka 'oko'a o ka puka wai komo no ka wai-condensers cooled. He ʻokoʻa wela liʻiliʻi (<5℃) may indicate insufficient heat exchange area (e.g., damaged fins), refrigerant leakage, or fan/pump failure. An excessively large temperature difference with high-pressure alarms may signal condenser blockage or internal pipe damage causing abnormal heat exchange efficiency.

Evaporator: He 10–15 degere ka ʻokoʻa ʻokoʻa o ka wela inlet-outlet no nā ʻōnaehana ea. Hiki ke hōʻike ʻia kahi ʻokoʻa liʻiliʻi i ka hewa ʻana o ka evaporator, nā kahe o loko, a i ʻole ke kahe ʻana o ka refrigerant lawa ʻole. ʻO kahi wela haʻahaʻa haʻahaʻa haʻahaʻa (<0℃) with persistent icing may stem from pipe blockage or sensor faults, which can cause evaporator freezing and cracking over time.

2.2 ʻIke ʻana i ke ʻano o ke kaomi

 

E hoʻohana i ka mīkini kaomi no ke ana ʻana i ka ʻōnaehana kiʻekiʻe a me ka haʻahaʻa haʻahaʻa: No ka R22 refrigerant, ʻo ke kaomi kiʻekiʻe maʻamau (ʻaoʻao condenser) ʻo 1.4–1.8MPa, a ʻo ke kaomi haʻahaʻa maʻamau (ʻaoʻao evaporator) ʻo 0.4-0.6MPa.

ʻO ke kaomi haʻahaʻa haʻahaʻa a me ke kaomi haʻahaʻa haʻahaʻa: Loaʻa nui ka leaka o loko (ke keʻa refrigerant -kahe) i loko o ka condenser a i ʻole evaporator.

ʻO ke kaomi kiʻekiʻe a me ke kaomi haʻahaʻa haʻahaʻa: E hōʻike paha i ka hoʻopaʻa ʻana o ka condenser a i ʻole ka paipu evaporator e hōʻino ana i ka holo ʻana o ka refrigerant.

Haʻahaʻa haʻahaʻa kiʻekiʻe a haʻahaʻa kaomi: E nānā no ka leakage refrigerant (evaporator/condenser perforation).

3. Ka Loiloi Hana

3.1 Hoʻemi ʻia ka hiki ke hoʻomaha / wela

 

Inā ʻaʻole hiki i ka wela o loko/puke i ka waiwai i hoʻonohonoho ʻia (ma hope o ka hoʻoholo ʻana i nā hemahema o ka mea hoʻoemi a throttling paha), e noʻonoʻo i ka pōʻino o ka evaporator a i ʻole condenser: Hoʻemi ka pōʻino o ka evaporator i ka lawe ʻana i ka wela; ʻO ka pōʻino condenser ke kumu o ka hoʻoheheʻe ʻana o ka wela, e hoʻoulu ana i ka pale ʻana i ke kaomi kiʻekiʻe a ke hoʻopau nei i ka pōʻaiapuni o ka pahu hau.Laʻana: Ke alakaʻi nei ka leak evaporator ea i ke kiʻekiʻe o ka ea o loko o ka hale waho, me ka holo ʻana o ka condenser o waho akā ʻaʻohe hopena hoʻomaha. ʻO ka pōʻino nui o ka puʻu condenser ke kumu o ka wela kiʻekiʻe ʻē aʻe i ka paipu kaomi kiʻekiʻe (me ka hana maʻamau o waho) a me ka pani ʻana o ka ʻōnaehana.

3.2 Ka leo ʻole a me ka haʻalulu

 

Hiki ke hōʻike ʻia nā ʻili metala mai ka peʻahi condenser e ʻoki ana i nā lau peʻahi a i ʻolepaipu condenser loose e hui aname ka pūpū.

Hiki i ke kani "hissing" mai ka evaporator ke hōʻailona i ka pōʻino o ka paipu i loko (leakage refrigerant) a i ʻole nahā paipu i ka wā e hoʻoheheʻe ʻia ma hope o ka hau.

4. Nā ʻano hoʻāʻo kōkua

4.1 Ho'āʻo Paʻa ʻEa

 

E hoʻopiha i ka ʻōnaehana me ka nitrogen (1.8–2.0MPa) a paʻa i ke kaomi no 24 mau hola: ʻO ka hāʻule ʻana o ke kaomi ma mua o 0.05MPa e hōʻike ana i ka leakage. E ʻimi i nā leaks ma ka hoʻopili ʻana i ka wai kopa i nā hui paipu evaporator/condenser a me nā wili (e nānā i nā ʻōhū). ʻO ka paʻa ʻana o ke kaomi maʻamau akā ʻaʻole i hōʻike ʻia ka pōʻino o ka paipu i loko.

4.2 ʻIke Kiʻi Infrared

 

E nānā i ka ʻili o ka evaporator/condenser me kahi kiʻi wela infrared: Loaʻa i nā ʻāpana hoʻololi wela maʻamau ka puʻunaue like ʻole. Hōʻike nā wahi wela kiʻekiʻe/haʻahaʻa kūloko i ka paʻa ʻana o ka paipu, leakage, a i ʻole ka hoʻololi ʻana i ka wela maikaʻi ʻole, e hiki ai ke hoʻopili pololei ʻia.

4.3 Aila Laana Anai

 

Wehe i ka aila pahu hau mai ka ʻōnaehana: ʻO nā ʻōpala metala (mai ka evaporator/condenser pipe wear) a i ʻole ka maʻu nui (mai ka pōʻino o ka paipu a me ke komo ʻana o ka wai) i loko o ka ʻaila e hōʻike ana i ka pōʻino mechanical -disassemble a nānā.

Hōʻuluʻulu manaʻo

 

No ka hoʻoholo ʻana i ka pōʻino condenser/evaporator, pono ke ala ʻehā-dimensional: "nānā hiʻohiʻona - nā ʻāpana - hana - hoʻāʻo". E hoʻopaʻa mua i ka nānā ʻana no ka hoʻopau ʻana i nā hemahema o ka ʻili, a laila e hoʻohana i nā mea hana e ʻike ai i nā mea ʻino ʻole, a hope e hōʻoia i ke ʻano pōʻino e pili ana i ka hana hana. I ka mālama ʻana i kēlā me kēia lā, hoʻomaʻemaʻe mau i nā wahi hoʻololi wela a nānā i nā ʻāpana hana e ʻike koke i ka pōʻino huna a pale i ka piʻi ʻana o ka hewa.
