Central air-conditioning system has been widely used in industrial and civilian areas, in hotels, restaurants, office buildings, shopping malls, inpatient building, industrial plant in the central air conditioning system, refrigeration compressors, refrigeration circulating water system, cooling water circulation systems, cooling towers Most of the capacity of the fan system is in accordance with the largest building cooling and heating load is selected, and then allow sufficient margin.
Not used with servo load regulation characteristics of closed cooling tower, no matter how the change of seasons, day and night, and user load, the cooling tower of the motors are running at full speed in a long-term fixed-frequency state, resulting in a huge waste of energy. In recent years, due to rising electricity prices, making the central air conditioning system operating costs rose sharply, causing it to occupy an increasing proportion of the total operating costs of the building, coupled with the current of the production, intense competition in services, the majority of corporate profits is not ideal .
Therefore, control energy costs has clearly become an issue where managers are concerned. According to statistics, more than 70% of the central air conditioning electricity accounts for the total electricity consumption of all types of buildings, so saving energy consumption of central air conditioning circulating water system, has very important significance.
Closed cooling tower energy conservation principle
1, closed cooling tower can adjust according to changes in ambient temperature and air volume spray volume, fluid coolers installed automatic control system to control the temperature based on the current start and stop the fan and sprinkler systems, maximizing efficiency and cooling process energy efficiency, saving energy waste.
2, with the closed cooling tower as compared to the traditional atmospheric cooling tower to achieve cooling water (pure water) is fully enclosed within the road circulation, thereby greatly increasing the ability to use the water cycle, and does not require digging pool, convenient Relocation.
Central air-conditioning use closed cooling tower as a cooling mode to maximize the realization of the central air conditioning circulating water system energy (power consumption, power consumption).
