Daim ntawv thov

Kev cog qoob loo

Qhov tseem ceeb yuav tsum tau rau lettuce cultivation HVAC:

Tsev cog khoom tuaj yeem tiv thaiv cov qoob loo los ntawm huab cua tsis zoo uas tso cai rau ntau xyoo puag ncig thiab muaj kev tiv thaiv zoo dua cov kab tsuag thiab kab mob, thiab tseem tau txais txiaj ntsig los ntawm lub hnub ci ntuj.Qhov kev nyab xeeb zoo tshaj plaws rau kev cog qoob loo ntawm lettuce yuav tsum tswj qhov kub thiab av noo ntawm 21 ℃ thiab 50 ~ 70%.Sab hauv tsev kub, av noo, tswj carbon dioxide thiab txaus irragation yog qhov tseem ceeb tshaj plaws rau kev cog qoob loo lettuce.

Local kub & humidity:28 ~ 30 ℃ / 70 ~ 77%

Sab hauv HVAC Tsim:21 ℃ / 50 ~ 70%.Hnub tim: qhov kub thiab txias;Hmo ntuj: kub tsis tu ncua.

Qhov project daws:

1. HVAC Tsim: Sab hauv tsev kub thiab av noo

1. Ob daim ntawm condensing sab nraum zoov chav tsev (Cov muaj peev xwm: 75KW * 2)

2. Ib thooj ntawm ntsug cua tuav chav tsev (Cov muaj peev xwm: 150KW, hluav taws xob cua sov muaj peev xwm: 30KW)

3. Ib daim ntawm PLC qhov kub thiab av noo tswj

Qhov cua txaus yog qhov tseem ceeb heev rau kev pom kev loj hlob ntawm cov nroj tsuag, tshwj xeeb tshaj yog nyob rau hauv cov ntaub ntawv ntawm sab nraud kub thiab hnub ci hluav taws xob.Thaum tshav kub kub yuav tsum tau muab tshem tawm tas li ntawm lub tsev xog paj.Muab piv rau qhov cua qhov cua, AHU nrog PLC tswj tau meej kom tau txais cov huab cua xav tau;nws tuaj yeem txo qhov kub thiab txias, tshwj xeeb tshaj yog nyob rau hauv qhov kub thiab txias ambient kub lossis hluav taws xob siab.Nrog lub peev xwm txias txias nws tuaj yeem ua kom lub tsev cog khoom kaw tag nrho, txawm tias nyob rau theem siab tshaj plaws.AHU tseem tuaj yeem muab cov tshuaj dehumidify lub zog kom tsis txhob muaj qhov sib xyaw ua ke thaum nruab hnub thiab tshwj xeeb yog ob peb teev tom qab hnub poob.

2. HVAC Tsim: Sab Hauv Tsev CO2 tswj kev daws teeb meem

1. Ib thooj ntawm lub zog rov qab lub tshuab ua pa (3000m3 / h, ib zaug huab cua hloov ib teev)

2. Ib daim ntawm CO2 sensor

CO2 enrichment yog qhov tseem ceeb los ua kom cov khoom zoo.Thaum tsis muaj cov khoom siv dag zog, cov tsev cog khoom yuav tsum tau tso cua thaum lub sij hawm loj ntawm ib hnub ua rau nws tsis yooj yim kom tswj tau qhov siab CO2 concentration.Qhov concentration ntawm CO2 nyob rau hauv lub tsev xog paj yuav tsum qis dua sab nraud thiaj li yuav tau txais cov dej ntws sab hauv.Nws txhais tau hais tias kev lag luam tawm ntawm kev ua kom muaj kev nkag mus ntawm CO2 thiab tswj kom muaj qhov kub txaus hauv tsev cog khoom, tshwj xeeb tshaj yog thaum hnub ci.

Lub tshuab ua pa rov qab lub zog nrog CO2 sensor muab cov tshuaj CO2 zoo tshaj plaws.CO2 sensor real-time saib sab hauv tsev concentration theem thiab precisely kho extract thiab muab airflow kom tiav CO2 enrichment.

3. Kev ywg dej

Peb xav kom siv ib lub tshuab dej chiller thiab thermal rwb thaiv tsev dej tank.Dej chiller txias peev: 20KW (nrog qhov hluav taws xob txias dej ntawm 20 ℃ @ ambient ntawm 32 ℃)
