the energy consumption of commercial properties is characterized by many varieties, large consumption and high cost.
the energy consumption of commercial properties mainly refers to the water, electricity, gas and oil consumed by commercial properties in the operation process, specifically, the lighting electricity needed for office and business operation of high-rise buildings, the power electricity needed for air conditioning operation of elevators, and the lighting electricity needed for peripheral lighting, advertising and image display; Electricity and water supply for air conditioning in toilets and offices, and water consumed in cleaning services; Artificial gas or natural gas consumed by restaurants and gourmet places; 1# diesel oil consumed in air conditioning and hot water supply, etc.
to do a good job in energy-saving management of commercial properties, we should start from the following aspects.
Use energy rationally and make energy-saving plans
Nowadays, most manufacturers want their counters and goods to have the brightest illumination in the store, so as to attract customers' attention. Unlimited increase in the illumination of the counter will not only waste electric energy, but even cause light pollution, which will bring uncomfortable feelings to shopping guests. Therefore, when decorating the counter, we should strictly follow the relevant standards and implement power load control; In addition to the corresponding approval, the excessive power consumption should also bear all the excessive expenses. In the non-store area, as long as sufficient illumination is ensured, it is not as bright as the store area. In this way, the energy-saving effect can be achieved through reasonable and scientific distribution.
In energy-saving management, special attention should be paid to the formulation of energy-saving plans. A more scientific method is to take 95% of the energy consumption of each property in the same period of last year as the planned energy consumption in the same period of this year, and make quantitative statistics and analysis on the implementation of the plans through monthly energy reports and monthly energy analysis. Its purposes are twofold:
First, to find out the abnormal situation in energy consumption, analyze the reasons and formulate corrective measures to eliminate it; Second, make a detailed summary of the places where energy-saving management is well done or worth popularizing and learning, and actively promote it in the management of other commercial properties, so as to achieve the effect of making good use of energy and saving energy.
Pay attention to maintenance and adopt new energy-saving technologies.
Central air-conditioning systems are mostly used in commercial properties, and the equipment that consumes the most energy in the central air-conditioning system is mainly the air-conditioning main unit, water pump and terminal equipment. Therefore, it is very important to regularly clean the condenser and evaporator water pipes of the refrigeration main unit, blow off the scale on the inner wall of the copper tube bundle, clean the temperature detectors, treat the chilled water and cooling water systems, and clean the fins of the variable air volume and fan coil units. Because the above work is done well, it can not only ensure the normal operation of the system and equipment, but also improve the heat exchange efficiency between the host and the terminal equipment, so as to give full play to the use efficiency of the equipment.
commercial properties can also adopt some feasible automatic control devices in the BAS system according to their actual conditions and with the permission of funds. At the same time, the application of frequency conversion technology in some places has also achieved remarkable energy-saving effects. For example, adding frequency conversion control system to secondary pumps can save more than 31% of electricity. In the air conditioning heating system, the transition from thermal oxygen removal to drug oxygen removal for boiler feed water can not only reduce oil consumption, but also eliminate oxygen corrosion of boiler body and prolong the service life of boiler.
under the premise of not lowering the service standard of commercial property, use energy scientifically and reasonably, pay attention to the maintenance of system equipment, strengthen training and inspection, strictly put an end to the waste of energy, and carefully inspect measuring instruments to ensure the accuracy of measurement data. At the same time, new energy-saving technologies are constantly introduced and adopted, and benefits are demanded from scientific management, so as to reduce the cost of energy consumption of commercial properties, purify the environment, benefit mankind and maintain ecological balance.
