By above experiment as can be known: this air conditioner Energy Efficiency Ratio when heating is suitable with traditional air-conditioning, but will exceed more than 40% than traditional heat pump air conditioner Energy Efficiency Ratio when refrigeration, and comprehensive Energy Efficiency Ratio is then higher.Office building as 30000 ㎡, per hour approximately must cold 3600KW in the summer process of refrigerastion, if select per hour power consumption=3600 ÷ 3.6(COP values of traditional heat pump air conditioner for use)=1029KW, and select this energy-conservation water-cooled air conditioner for use, power consumption=3600 ÷ 5.15(COP values per hour when freeze summer)=699KW, 329 degree per hour can economize on electricity, move 10 hours every day and can economize on electricity 3300 degree, every degree electricity is by 1 yuan of calculating of commercial electricity price, can save 100,000 yuan of the electricity charge in every month, annual refrigerating operaton can be saved the electricity charge in 5 months more than 500,000 yuan, so economic benefit is considerable.
(4) with traditional air conditioner ratio, save installation space and cooling water pipeline, reduced installation cost.
This air conditioner is installed in outdoor, as roof or vacant lot downstairs, adopt integrated design, media water pump, cooling water pump all are positioned at this equipment, therefore with traditional Water cooled air conditioners ratio, saved the air-conditioning equipment machine room, saved that a large amount of interior spaces and cooling water pipeline are purchased, the input cost of installation and regular maintenance.
Select for use this air-conditioning to reduce to have reduced behind the machine room construction cost about 10% according to measuring and calculating, saved purchasing and installing of cooling water pipeline, it is about 20% then can to reducing the construction costs, and the regular maintenance cost also can reduce in a large number.Therefore it is about more than 30% to select for use this air-conditioning can reduce total construction cost.
