ʻO ke ʻano a me nā ʻano o ka pahu hau evaporator

He aha ka pahu hau evaporator?

ʻO ka evaporator friji kekahi mea hoʻololi wela nui o ka ʻōnaehana refrigeration. He mea ia e hoʻopuka i ka mana anuanu i loko o ka mea hoʻoheheʻe, a ʻo ia ka mea nui no ka "heat absorption". ʻO nā mea hoʻoheheʻe pahu hau i hana nui ʻia me ke keleawe a me ka aluminika, a aia nā ʻano pāpaʻi (aluminium) a me nā ʻano paipu uea (platinum-nickel steel alloy). Hoʻopili wikiwiki.

ʻO ka hana a me ke ʻano o ka evaporator refrigerator

Hoʻokumu ʻia ka ʻōnaehana hoʻoheheʻe o ka pahu hau me ka mea hoʻoheheʻe, kahi evaporator, kahi mea hoʻomaʻamaʻa, a me kahi paipu capillary. I loko o ka ʻōnaehana refrigeration, ʻo ka nui a me ka hāʻawi ʻana o ka evaporator e pili pono i ka hiki ke hoʻomaha a me ka wikiwiki o ka ʻōnaehana friji. I kēia manawa, ʻo ka ʻāpana paʻukū o ka pahu friji ma luna aʻe nei ka hapa nui o ka refrigerated e kahi evaporator papa hoʻololi wela. Aia ka drawer o ka pahu pahu hau ma waena o nā ʻāpana o ka papa hoʻololi wela o ka evaporator. Hoʻokaʻawale ʻia ke ʻano o ka evaporator i nā coils uea kila. ʻElua mau hale o ke ʻano paipu a me ke ʻano coil plate alumini.

ʻO ka meamaikaʻi ka evaporator refrigerator?

ʻElima ʻano o nā evaporators maʻamau i hoʻohana ʻia i loko o nā pahu hau: ʻano coil finned, ʻano pahu pahu aluminika, ʻano wili wili kila, a me ka ʻano paipu hoʻokahi.

1. Finned coil evaporator

ʻO ka evaporator coil finned he evaporator intercooled. He kūpono wale ia no nā friji indirect. ʻO ka pahu alumini a i ʻole ke keleawe keleawe me ke anawaena o 8-12mm ka hapa nui i hoʻohana ʻia e like me ka ʻāpana tubular, a ʻo ka ʻāpana alumini (a i ʻole ka ʻāpana keleawe) me ka mānoanoa o 0.15-3nun e hoʻohana ʻia e like me ka ʻāpana hope, a ʻo ka mamao ma waena o nā fins. he 8-12mm. Hoʻohana nui ʻia ka ʻāpana tubular o ka hāmeʻa no ka holo ʻana o ka refrigerant, a hoʻohana ʻia ka ʻāpana hope e hoʻomoʻa i ka wela o ka friji a me ka pahu hau. Ua koho pinepine ʻia nā evaporators coil ma muli o ko lākou kiʻekiʻe kiʻekiʻe o ka hoʻololi ʻana i ka wela, ka wāwae liʻiliʻi, ka paʻa, ka hilinaʻi, a me ke ola lōʻihi.

2. Aluminum pā puhi evaporator

Hoʻohana ia i kahi paipu paʻi ma waena o nā papa alumini ʻelua, a ma hope o ka calendering, hoʻopili wela ka ʻāpana i paʻi ʻole ʻia, a laila puhi ʻia i ke alanui ʻohe e ke kaomi kiʻekiʻe. Hoʻohana ʻia kēia evaporator i loko o nā keʻena hoʻoheheʻe o nā pahu pahu pahu hoʻokahi i ʻoki ʻia, nā pahu pahu pahu pālua, a me nā pahu pahu pahu liʻiliʻi liʻiliʻi, a ua hoʻokomo ʻia ma ka ʻaoʻao luna o ka paia hope o ka pahu hau ma ke ʻano he papa pālahalaha.

3. Tube-papa evaporator

ʻO ia ke kulou i ka paipu keleawe a i ʻole ka pahu alumini (ma ke ʻano he 8mm ke anawaena) i kekahi ʻano, a hoʻopaʻa (a i ʻole braze) me ka pā alumini hui. I waena o lākou, hoʻohana ʻia ka paipu keleawe no ka holo ʻana o ka refrigerant; hoʻohana ʻia ka pā alumini e hoʻonui i ka wahi conduction. Hoʻohana pinepine ʻia kēia ʻano evaporator e like me ka evaporator paʻukū a me ka hoʻoluʻu pololei ʻana o ka pahu hau hoʻoluʻu pololei.
