Summary of central air-conditioning energy-saving measures in Suzhou law code
As a super-power electrical appliance, central air-conditioning is the main force of electricity consumption in modern buildings. The energy-saving of central air-conditioning system is related to the development and popularization of central air-conditioning. The research and development of energy-saving measures for central air-conditioning is very important. Energy-saving measures of central air-conditioning system: using frequency conversion technology Inverter central air-conditioning is to add a frequency converter to the structure of conventional air-conditioning, which can adjust the operating speed of the air-conditioning compressor at any time, so as to achieve rational use of energy. Since its compressor will not be turned on frequently, it will keep the compressor in a stable working state, which can make the overall air conditioner achieve the effect of saving more than 30% of energy. Energy-saving measures of central air-conditioning system: using water cooling technology Water cooling technology is to use the peak-valley electricity price difference of the power grid. At night, chillers are used to store cold in the pool, and the stored cold energy is released to the air-conditioning system during the peak hours of electricity during the day. technology. From a macro perspective, water storage technology can play the role of 'shaving peaks and filling valleysIt can save users a lot of central air-conditioning annual operating costs every year. Energy-saving measures of central air-conditioning system: fresh air heat recovery technology Using heat recovery technology, the exhaust air is used to preheat (or pre-cool) the fresh air to save air conditioning energy consumption. For example, in summer, the cold energy in the exhausted air is recovered, and then the hot outdoor air is pre-cooled and sent indoors (as shown in the lower left picture: the outdoor air at 32°C is pre-cooled to 27.8°C); in winter, the heat of the exhaust air is recovered, and then the outdoor The hot air is preheated and sent into the clean room modular (as shown in the lower right picture: the outdoor air at 7°C is preheated to 16°C), thereby reducing energy loss and reducing the energy consumption of air conditioning for cooling and heating air. Energy-saving measures of central air-conditioning system: cold (heat) measurement We can use basic mathematics and physical knowledge to measure the total amount of cold (heat) used by central air-conditioning, which can improve energy-saving awareness and reduce ineffective cold (heat) It is convenient to charge and manage the use of cold (heat) energy.
