solve the problem : solve users' daily five 45 t hot water demand

Solution

1: Hot water design Daily heat consumption

Summer ninety day = one hundred and fifty-seven kw      Spring and Autumn one five five day = one hundred and ninety-two kw      winter one two zero day = 203.5k w:

       2: Hot water design calculation

     one winter When The ambient temperature is - At 5.0 ℃ At this time, Lipman ten P hot water The heating capacity of the unit is nineteen point three four k w , using Lipman air source heat pump water heater A·C ten -HW -S2   common one platform Equipped with five kw Electric assistant Standby heat source heating 10.5 It can be satisfied in all hours in winter five Tons of hot water demand.

     two )Spring and Autumn season When the ambient temperature is At 15 ℃, Now Lipman ten P hot water The heating capacity of the unit is thirty-three point three four k w , heating 5.8 Hours is enough spring and autumn All day maximum five Tons of hot water demand.

     3) Summer When the ambient temperature is At 27.3 ℃, Now Lipman ten P hot water The heating capacity of the unit is forty-two k w , heating 3.8 Hours is enough summer All day maximum five Tons of hot water demand.

     The selection of air source heat pump unit should meet the most unfavorable conditions in winter choice one platform 380v Lipman air source heat pump water heater A·C ten -HW -S2 Equipped with five kw Electric assistant Standby heat source

 

hot water function Electricity quantity

summer

(9.2KW+0.55KW)×3.8h = thirty-seven point zero five KW·h

Spring and Autumn

(8.4KW+0.55KW)×5.8h = fifty-one point nine one KW·h

winter

(7.44KW+0.55KW)×10.5h = eighty-three point nine KW·h

Average power consumption per day

(37.05 kW · h × 90 days + 51.91 kW · h × 155 days + 83.9 kW · h × 120 days) / 365 days / 5t= eleven point seven five kw·h/ T ·Days


Engineering cases Six winter, tens of millions of square meters of heating and hot water model project

After more than 10 years of research and development of air source heat pump units, Lipman's projects have covered various fields, including residential areas, commercial office buildings, hotels, schools, hospitals and other fields, to meet the needs of different scenarios for cooling, heating and hot water.
