29/01/2019 · Fuel cost: 1 ton of gas boiler consumes 80 cubic meters of natural gas per hour, 8*3=24 RMB/hour; labor cost: 2000RMB, heating 70,000 square meters of office building or residential hourly cost approx is: 1920+26+24+8.3=1978.3 RMB, working 10 hours on day, working 300 days one year, the total cost of one year: 1978.3*10*300=5934900 RMB. After the heating boiler cost and heating cost
chiller + gas boiler (WB) system was also simulated. The results showed that the hybrid system would provide a better indoor comfort and remains at the thermal comfort class I, the hybrid system would incur a 14.5% lower cost but would provide 43.2% more energy saving. The hybrid GSHP system could reduce 20.23 tons of CO 2 emission, while 1.39 tons more SO 2, 0.39 tons more NO x and 9.70 tons
07/11/2016 · For example, a typical office building minimally complying with the ASHRAE Standard 90.1 might use 75,000 Btu/sq.ft./yr. The goal for many federal buildings is 50,000 Btu/sq.ft./yr. A highly energy-efficient building using conventional comfort could have an energy use of 40,000 Btu/sq.ft./yr. or even less. A building designed and operated with
In these diagrams, 1&2, 3&4, 5&6 have been linked together in pairs to make it easier to fit the wires into the terminals. 7 and 8 are used to connect each thermostat output to the zone valve input. 9 connects the switched outputs from the valves to the boiler input.
