High initial investment and space occupation; Frequent start stop of equipment, shortened lifespan, insufficient dehumidification, and indoor humidity.
Capacity too small
Extreme weather cannot reach the set temperature, with many complaints, and later forced installation of equipment and repeated investment.
Unbalanced wind system
Insufficient air flow in remote rooms and undercooling in the near end result in users opening windows for heat dissipation, leading to an increase of over 20% in energy consumption.
The water system has not undergone hydraulic balance
Some coils have excessive flow and a temperature difference of only 1-2 ° C, causing the water pump to circulate in vain and doubling the pump consumption.
Insufficient or excessive fresh air volume
Shortcomings: High CO ₂, drowsiness, and easy growth of mold; Excessive: The cold and heat load has increased dramatically, and the heating/humidification costs have skyrocketed in winter and summer.
Pipeline direction conflict
The air duct and structural beam got into a fight, and the suspended ceiling was raised on site, with the floor height reduced from 2.8 meters to 2.4 meters, resulting in cramped space and high costs for secondary decoration and renovation.
No heat recovery is set up
In winter, the exhaust temperature is directly discharged at 22 ° C, and heating the fresh air consumes steam, resulting in a 15% increase in boiler gas consumption.
Remote computer room layout
The one-way chilled water pipe is 200 meters, the pump head increases by 15 meters, and the annual pump consumption is 30000 kWh more; Moreover, the long pipeline experiences significant heat loss and fluctuations in water temperature at the end.
