I. Ɔhyew a Wɔde Sesa Nneɛma Yiye a Wɔde Toto Ho: Plate Heat Exchangers De Mfaso Ahorow Ma
1. Plate Heat Exchanger: Ɔhyew Nsesae a Ɛkorɔn yiye
Mprɛte ɔhyew sesafo no de mprɛte nhyehyɛe a ɛyɛ corrugated di dwuma, na ɛma nsu a ɛwɔ akwan teateaa no mu no ma basabasayɛ a ɛkorɔn-ba wɔ Reynolds nɔma a ɛba fam mpo mu, na ɛnam so yi nsɛm a ɛfa nsu a ɛtwa ne stagnation ho no fi hɔ koraa.Ne ɔhyew a ɛkɔ baabi foforo nsusuwii betumi adu 1,500–5,500 W/(m2·℃)-abiɛsa kosi anum mpɛn dodow a ɛyɛ nea wɔde di dwuma wɔ shell-ne-tube ɔhyew sesa nneɛma a wɔtaa de di dwuma no mu. Bio nso, nsɛm ho amanneɛbɔ a ɛyɛ nwini ne nea ɛyɛ hyew no sen wɔ ɔkwan a ɛne mprempren de bɔ abira koraa so wɔ adeyɛ no nyinaa mu, na ɛde ɔhyew mu nsonsonoe a wɔde di dwuma kɛse soronko ba; nsonsonoe a ɛwɔ ɔhyew a ɛwɔ awiei no mu no betumi ayɛ nea ɛba fam te sɛ digrii 1 , na ama wɔahwɛ ahu sɛ ɔhyew a wɔde sesa no yiye. Wɔ adwumayɛ tebea horow a ɛyɛ pɛ mu no, eyi kyerɛ sɛ ahoɔden a wɔde di dwuma no so tew na ɔhyew a wɔhwere no sua.
2. Shell-ne-Tube Heat Exchanger: Ɔhyew a wɔde sesa no yiyedi no yɛ nea ɛkɔ fam kosi nea ɛba fam.
Wɔ shell-ne-tube heat exchangers mu no, nsuo sen fa tube fã ne shell fã no mu wɔ ɔkwan soronko so; ne saa nti, afrafra a ɛyɛ basabasa no yɛ mmerɛw, na ɛma nsu a awu ne akwan a wɔfa so twa ho no ba. Ne saa nti, ɔhyew a ɛkɔ baabiara no taa fi 300 kosi 1000 W/(m2·℃) pɛ. Nsonsonoe a ɛwɔ ɔhyew mu nsonsonoe a ɛda nneɛma a ɛyɛ hyew ne nea ɛyɛ nwini ntam no a wɔde di dwuma yiye no sua, na nsonsonoe a ɛwɔ ɔhyew a ɛwɔ awiei a wɔtaa de di dwuma no boro digrii 5 . Sɛnea ɛbɛyɛ na wɔadi ɔhyew a wɔde fa so a ɛyɛ pɛ ho ahwehwɛde ahorow ho dwuma no, ɛho hia sɛ wonya ɔhyew a wɔde fa so no ani kɛse, na ɛma ahoɔden a wɔde di dwuma nyinaa yɛ kɛse bere a wɔde toto mprɛte so ɔhyew a wɔde sesa nneɛma ho no.
II. Ntotoho a Wɔde Yɛ Nneɛma a Wɔahyehyɛ ne Nea Wɔde Sesa Nneɛma: Mprɛte so Ɔhyew a Wɔde Sesa Nneɛma no Yɛ Nneɛma a Ɛyɛ Fɛ na Ɛyɛ Hare
1. Plate Heat Exchanger: Ne kɛse yɛ ketewaa, emu yɛ hare, na ɛnyɛ den koraa.
Plate ɔhyew sesafo no wɔ nhyehyɛe a ɛyɛ ketewaa kɛse, a ɔhyew sesa no ani kɛse wɔ unit volume biara mu fi 200 kosi 1000 m2/m3-boro shell-ne-tube mfiri so koraa.
