Experimental Study on Air Conditioning Energy Consumption of an Office Building in Qingdao

More and more office buildings are built and consequently, the building energy-consumption increases especially air conditioning energy consumption. The energy consumption of air conditioning is monitored in an office building in Qingdao, and the test results show that refrigerator installed capacity is too large and COP is low, cooling circle pumps and chilled water pumps are oversize and water transport factor is lower than the standard value, the efficiency of the cooling tower is also very low. Based on experimental result, corresponding energy saving measures are proposed.
