Q1: Sei zvakadaroheat exchangersinodiwa muHVAC masisitimu?
Heat exchangers ndechimwe chezvinhu zvakakosha muHVAC (Kupisa, Kufefetedza, uye Air Conditioning) masisitimu. Iwo anonyanya kushandiswa kutamisa simba rekupisa zvakanaka pakati pemvura dzakasiyana, kutsigira kupisa, kutonhora, kudzoreredza kupisa, uye tembiricha mutemo.
Mabasa makuru anosanganisira:
1. Kuendesa kupisa uye kutonhora simba
A heat exchanger inotamisa kupisa pakati pezvinotonhora uye zvinopisa zvinwiwa kuburikidza nesimbi kupisa kupisa pamusoro, uku ichidzivirira iyo miviri miviri kubva kusanganisa zvakananga.
Mumhepo inogadzirisa masisitimu, iyo inopisa inopisa inotamisa kupisa kubva mufiriji kuenda kumhepo kana mvura, kuwana kutonhora kana kupisa mhedzisiro.
2. Kuvandudza kushandiswa kwesimba
-inobatisa kupisa inokwanisa kuderedza kushanda kwemacompressor, boilers, uye chiller, zvichibatsira kuderedza kushandiswa kwesimba.
Sarudzo yakakodzera yekuchinjisa kupisa inogona kuvandudza kushanda kwese kweHVAC uye kuderedza-mari yekushandisa kwenguva refu.
3. Kuve nechokwadi chekushanda kwehurongwa hwakagadzikana
Iyo yekupisa yekupisa dhizaini inofanirwa kusangana nekumanikidza kwehurongwa, tembiricha, uye kuyerera zvinodiwa kuti ive nechokwadi chekushanda kwakavimbika pamusoro pehupenyu hurefu hwesevhisi.
Mushonga wakakodzera wekupisa unogona kuchengetedza kushanda kwakagadzikana kwekushisa kwekushisa pasi pemamiriro akasiyana ekushanda.
Q2: Ndeapi marudzi eheat exchangersanowanzo shandiswa muHVAC masisitimu?
Zvinoenderana neakasiyana zvimiro uye mashandisirwo, anonyanya kuzivikanwa eHVAC ekupisa anopisa anosanganisira anotevera marudzi

Q3: chiiheat exchangerndiyo yakanakisa sarudzo yeHVAC masisitimu?
Iko hakuna imwe yekupisa yekupisa inokodzera zvese zveHVAC application. Sarudzo yakanakisa zvinoenderana nezvinodiwa system, mamiriro ekushanda, uye nharaunda yekuisa.
Mitemo yekusarudza inosanganisira:
1. Kusarudzwa kunobva pane system type
Central air conditioning mvura masisitimu:
Michina yekudziya ndiro inowanzosarudzika nekuda kwekushanda kwayo kwepamusoro, compact size, uye kushanda zvakanaka mumvura-ku-maapplications ekufambisa kupisa kwemvura.
Zvivakwa zvakakura zvekutengesa kana maindasitiri HVAC masisitimu:
Shell nechubhu zvinodziya zvinopisa zvakanyanyokodzera kukwirisa{{0}kuremerwa uye kuenderera mberi kwenzvimbo.
Mhepo inobata masisitimu:
Finned tube heat exchangers anoshandiswa zvakanyanya nekuti anopa anoshanda kupisa kwemhepo uye kutonhora kuita.
Zvivakwa{0}zvinochengetedza magetsi:
Kupisa kudzoreredza kupisa kunopisa kunogona kuderedza zvakanyanya kufefetera simba rekushandisa uye kuvandudza hurongwa hwese hwese.
Q4: Ndezvipi zvinhu zvinofanirwa kutariswa pakusarudza kupisa kunopisa kune HVAC masisitimu?
1. Kuwedzera kupisa simba
Kupisa kunodiwa kana kutonhora kunofanirwa kutanga kwatemwa.
Iyo nzvimbo yekupisa yekupisa inofanirwa kusangana neyakakura system mutoro zvinodiwa kuti udzivise kusakwana kwekutamisa kupisa uye kuderedzwa kwemaitiro ehurongwa.
Iyo yakakosha kupisa equation ndeye:
Q = U × A × ΔT
Kupi:
Q:Mwero wekutamisa kupisa (W)
U:Zvose zvinopisa kupisa coefficient
A:Nzvimbo yekuendesa kupisa
ΔT:Avhareji yetembiricha musiyano pakati pemvura inopisa neinotonhora
2. Kushanda tembiricha uye kumanikidza
Iyo inopisa yekupisa inofanirwa kugadzirwa zvinoenderana nehupamhi hwekushanda tembiricha uye kudzvanywa kweHVAC system.
Kuwedzera-tembiricha uye{1}}kudzvanywa kwepamusoro kunoda zvinhu zvakasimba uye zvivakwa zvakasimba.
Mafiriji masisitimu anoda kutariswa kwakanyanya kune refrigerant pressure ratings kuti ive nechokwadi chekushanda kwakachengeteka.
3. Fluid maitiro
Zvinhu zvinotevera zvinofanira kufungwa nezvazvo:
Kunyangwe iyo fluid inogona kukonzera kuyera.
Kuti mvura yacho inoora here.
Fluid viscosity.
Ingave mvura ine zvidimbu kana tsvina.
Mienzaniso:
Nzira dzemvura dzakachena dzakakodzerwa neplate heat exchangers.
Fluids ine yakakwira fouling inogoneka zvirinani kugoko uye chubhu heat exchanger.
4. Kushanda kwesimba uye mari yekushandisa
-zvinobatisa kupisa zvakanaka kwazvo zvinogona kuderedza kushandiswa kwesimba kubva papombi, mafeni, macompressor, nemimwe michina.
Lower pressure loss inobatsira kuderedza mari yekushandisa.
Nguva refu-kuchengetedza simba kunofanirwa kutariswa paunenge uchisarudza chekuchinja kupisa.
5. Kuchengetedza uye hupenyu hwebasa
Kugara uchiongorora uye kucheneswa kunodiwa kuchengetedza kupisa kutamisa kuita.
Plate heat exchangers zviri nyore kupatsanura uye kuchenesa asi zvinoda kutarisisa kuchembera kwegasket.
Shell uye machubhu ekupisa anotsinhanisa akasimba zvakanyanya asi angangoda maitiro akaomarara ekuchenesa.
Q5: HVAC inogona kuvandudzwa sei kupisa kwekushisa?
1. Gara uchichenesa nzvimbo dzekufambisa kupisa
Chikero, tsvina, uye madhipoziti anogona kuwedzera kupisa kwekupisa uye kuderedza kupisa kwekufambisa kushanda zvakanaka.
Kuchenesa nguva dzose kunobatsira kudzorera kushanda uye kuderedza kushandiswa kwesimba kusingakoshi.
2. Kugadzirisa kuyerera kwemvura
Chengetedza kuyerera kwemvura inopisa uye inotonhora mukati meiyo yakagadzirirwa kushanda.
Kuyerera kusina kukwana kunoderedza kupisa kwekuita basa, nepo kuyerera kwakanyanya kunowedzera kurasikirwa kwekumanikidza uye kushandiswa kwesimba.
3. Sarudza zvinhu zvakakodzera
Simbi isina simbi inokodzera mvura{{0}yakavakirwa paHVAC masisitimu.
Titanium inokurudzirwa kumvura yegungwa kana nzvimbo dzine ngura zvakanyanya.
Kusarudzwa kwezvinhu zvakakodzera kunovandudza kusimba kwemidziyo uye hupenyu hwebasa.
4. Simbisa kutarisa kwekushanda
Gara uchitarisa tembiricha yekupinza uye yekubuda, misiyano yekumanikidza, uye kuyerera kwemazinga.
Kukurumidza kuona kuyera, kuvharika, kana kuderedzwa kwekuita kunogona kudzivirira kutadza kusingatarisirwe.
