Muaj ib tug nightclub nrog thaj tsam ntawm 600 square meters. Nws muaj lub ru tsev gable nrog qhov siab ntawm 8 meters hauv nruab nrab thiab 5 meters ntawm ob sab. Cov phab ntsa thiab lub ru tsev yog tag nrho ua los ntawm pob zeb wool suab rwb thaiv tsev boards. Nws tuaj yeem ua tau 1,300 tus neeg. Qhov kub ntawm sab nraum zoov yog 30℃rau peb lub hlis sib law liag. Yuav ua li cas muaj pes tsawg kilowatts ntawm ib zaug - cua txias cua txias muaj peev xwm?
1. Core Thaum tshav kub kub Load xam
1) Cov neeg ua haujlwm kub dissipation (lub ntsiab load
• Per capita heat dissipation:
Cov dej num hnyav (dancing / haus dej) raug them ntawm 300W rau ib tus neeg (sensible heat + latent heat).
Tag nrho cov load=1300 neeg × 0.3kW=390 kW
2) Kev hloov hluav taws xob hauv tsev
Lub tshav kub hloov coefficient ntawm pob zeb wool suab rwb thaiv tsev board: U nqi ≈0.5 W / (㎡·K) (zoo rwb thaiv tsev kev ua tau zoo).
• Ru tsev / Phab ntsa kub sib txawv: 30℃sab nraum zoov → 24℃phiaj sab hauv tsev, ΔT=6℃.
Thaum tshav kub kub hloov tsheb muaj peev xwm=600㎡ × 0.5W/(㎡·K) × 6K=1.8 kW (tsis pom zoo).
3) Cov khoom siv yog overheating
• Teeb pom kev zoo / Suab: LED loj screen + laser teeb kwv yees li 20kW, 50% hloov mus rau hauv tshav kub → 10kW.
• Wine tub yees: Lub tshav kub dissipation ntawm lub compressor yog kwv yees li 5kW.
4) Cov huab cua ntshiab
Qhov tsawg kawg nkaus huab cua ntim: Ntawm 30m³ / (h· neeg), 39,000m³ / h yog xav tau rau 1,300 tus neeg.
Txias thiab dehumidification load:
Kom txias cua sab nraum zoov ntawm 30℃/ 70% RH txog 24℃/ 50% RH, kwv yees li 120kW yuav tsum tau (xws li siv txoj kev sib txawv enthalpy).
2.Tag nrho txias Peev Xwm Xav Tau
• Instantaneous ncov load:
390 (cov neeg ua haujlwm) + 1.8 (cov tsev) + 10 (cov khoom siv) + 120 (cua sov) ≈ 522 kW
• Kev nyab xeeb margin (20%):
Qhov kawg thov=522 × 1.2 ≈ 626 kW
3. Kev daws teeb meem
Khoom npe: Rooftop Package Air Conditioning Unit
Number: 2 units ntawm WKLF310 uas tsuas yog ua kom txias
Kev teeb tsa: WKLF310 tuaj yeem muab tso rau hauv av ntawm ib sab ntawm lub tsev, cov neeg siv yuav tsum tau txais qee qhov cua ducts los txuas nrog WKLF310, yog li cov cua txias xa mus rau hauv chav tsev los ntawm cov cua ducts. Cov cua ducts faib cov cua txias kom sib npaug hauv chav tsev.
