[ ZHE ] air compressor water heater and other heating equipment comparison

Natural gas:

As the water requirements of1 tons with 20 ℃temperature to 60 ℃, provided by natural gas:

Natural gas combustion value 8500kcal/m3, natural gas combustion efficiency of 90%, natural gas price3 yuan /m3.

Requirements of heat load Q=cm △t=1 × 1000×(60 ℃- 20) =40000( kcal )

Consumption:40000/8500/0.9=5.22M3

1tons of water at 60 ℃cost: 5.22m3 × 3yuan /m3=15.66 yuan

Coal fired boiler:

As the water requirements of1 tons with 20 ℃temperature to 60 ℃, provided by coal fired boiler:

Coal combustion value 5000kcal/ kg, the combustion efficiency of coal40%, coal at1000 yuan / ton required heat load Q=cm △t=1 × 1000×(60 ℃- 20) =40000( kcal )

Coal consumption:40000/5000/0.4=20 kg1tons 60

Water costs:20 kg x 1yuan / kilogram =20 yuan

Diesel stove:

As the water requirements of1 tons with 20 ℃temperature to 60 ℃, furnace is provided by diesel:

Diesel combustion value 10200kcal/ kg,88% diesel oil furnace efficiency, heat loss of pipeline5%, diesel price7.5 yuan / kilogram. Requirements of heat load Q=cm △t=1 × 1000×(60 ℃- 20) =40000( kcal )

Fuel consumption:40000/10200/0.88/0.95=4.69 kg1tons 60

Water costs:4.69 × 7.5=35.17yuan / ton

Electric water heater:

As the water requirements of1 tons with 20 ℃temperature to 60 ℃, the electric water heater ( heating provides electricity 0.8 yuan / degree ):

Per hour yield (20 ℃temperature to 60 ℃) m =1000kg required heat load Q=cm △t=1 × 1000×(60 ℃- 20 ℃) =40000( kcal )860kcal/ value of electric heating, electric heater efficiency95%,0.8yuan / degree.

1tons of power consumption:40000/860/0.95=48.95( deg / h).

1tons of electricity consumption:48.95 × 0.8=39.16( yuan / hour ).

Solar heater.

As the water requirements of1 tons with 20 ℃temperature to 60 ℃, composed of a solar water heater is provided for heating ( report 0.8 yuan / degree ):

Solar water heater in the absence of the sun's environment, heat energy utilization rate is almost0, must rely on electric auxiliary heating is hot water, as the saying goes, is the use of electric heating water boiling, according to the year of two months of rainy or cloudy computing.

According to the electric water heater burning1 tons of water consumption of electricity : 48.95× 0.8=39.16yuan / ton if your company with 10tons of water a day, i.e. every day of electricity is:39.16 yuan / ton x 10tons / day =391.6 yuan / day or three month's bill is:391.6 yuan / day x 60 days = 23496yuan a year of in water for 365 days× 10 tons / day = 3650tons.

An average of per ton water cost:23496 yuan /3650ton = 6.43yuan / ton.

Air energy heat pump:

If the required1 tons with 20 ℃to 60 ℃hot water heating, air can heat pump heating is provided by ( report 0.8 yuan / degree ):

10HP air can heat pump parameters : hourly water (20 ℃te, m, , , , , , perature to 60 ℃) m =1000kg air can heat pump10HP type power9.5KW.

Air can heat pump producing 1 tons of water (20 ℃temperature to 60 ℃) costs:9.5KW/h ×1H × 0.8yuan =7.6 yuan.

[ and the ] air compressor water heater:

Zero heating cost: it is a kind of waste heat utilization equipment, the installation, and no increase in air compressor itself load,100% using air compressor waste heat to produce hot water, does not need any auxiliary heating device, so the heating cost is zero.
