Central air conditioning system in a commercial and residential energy-saving measures

b]. Therefore, the disabled and out of the cooling tower water valve should be closed to prevent the mixture of high and low temperature of the water leaving the cooling water temperature. Woodcrest Hill gold design in the cooling tower and chillers are equipped with electric at the inlet butterfly valve, and with the chain of connected electrical equipment when equipment stops running when the valve automatically closes,[link widoczny dla zalogowanych], effectively improve the efficiency of the cold source, 4 to reduce pump power consumption air-conditioning system is the role of the pump to overcome the chilled water and cooling water flow resistance in the pipeline to provide equipment to send high level, its power consumption is very large. As the outdoor temperature and humidity in the cooling season and for the heating season is changing, it is estimated that the load most of the year is only about 50% of maximum load. In traditional air conditioning systems, water pumps working condition is fixed, that is, given water system, cooling and heating load decreases,[link widoczny dla zalogowanych], water supply does not change, which creates energy waste . Woodcrest Hill gold plant is currently used air-conditioning system is technically more advanced variable-speed pump, variable frequency drive pumps to change the current frequency to change the water pump water pump speed and flow, so that with the hot and cold water supply to the load changes. In the measured energy-saving effect is very obvious in the owners are very satisfied with this. 5 reduce the pipeline resistance often occur in the actual project to reduce water flow if some room there will be summer temperatures do not fall down the situation, air-conditioning system had to increase traffic, reduce the temperature difference between chilled water supply to run. The main reason this happens is the slip resistance of each water system imbalance, the summer belongs to the overheated room, slip resistance, when the flow decreases,[link widoczny dla zalogowanych], the slip stream References: reduced to the extent not meet the needs, causing the room to overheat. If you increase the chilled water flow, the slip resistance will be more than the required water flow, thereby increasing energy consumption. In this regard, the design of gold Woodcrest Hill Air Conditioning Service Road side of each tube was more accurate calculation of resistance and support in all the way to set the hydraulic balancing valves, balancing the system to maximize the resistance of each branch. 6, strengthen management, reduce the fan (cabinet) in the fan power consumption air conditioning system including air conditioning and other air blower cabinet,[link widoczny dla zalogowanych], exhaust fan, power consumption of these devices the ratio of total power consumption of air-conditioning system is the largest, but its greatest potential for energy conservation. Gold Woodcrest Hill air conditioning system in the delivery of the design and construction unit together for the owners to develop a more comprehensive operation and management regulations, stressed the need to periodically clean the air handling and fan coil filter on , the fan should be regular maintenance, transmission should be maintained in good condition operation and management should step up inspection and found no personnel to stay inside air-conditioned room, you should turn off the end of the device to reduce power consumption. While promoting energy conservation should be strengthened, so that the user actively cooperate with each air-conditioning, so that people from the machine stops. 7, several measures through the above conclusion, gold Woodcrest Hill air-conditioning system energy saving effect is very obvious, and this effect with the company through the construction of an office building earlier comparison drawn. In 2001, 7 September, the building air conditioning system power consumption is only the actual monthly payment Woodcrest Hill more than 3 million degrees, the operating cost of about 4 million more. At present, the construction of large commercial buildings, commercial building energy consumption as well. Therefore, urgent and commercial building energy-saving potential.
