Because the cooling water system uses the best transfer efficiency control, had guaranteed the central air conditioning main engine in the full load and in the partial load situation, is at the best active status, throughout maintains the best energy use factor (namely the COP value), thus reduced the air conditioning main engine energy consumption, simultaneously because the cooling water pump and the cooling tower air blower frequently in are lower than under the fixed load to move, also maximum limit saved the cooling water pump and the cooling tower air blower energy consumption.
2) auxiliary engine energy conservation: Each kind pumps the kind (freezing to pump, cold water pump, air blower and so on) the movement energy conservation. Uses has the space vector control the frequency conversion velocity modulation way, changes the proportioning pump the variable displacement pump. Auxiliary engine energy conservation many to 40%
3) optimizes the auxiliary engine movement pattern: Generally when full load pumping machine needs the full speed movement, has not conserved energy the space, but uses the redundant technology and the frequency conversion technology unifies, the proportioning pump and the variable displacement pump coordinate, the optimized movement pattern, may cause the auxiliary engine unit to synthesize the energy conservation.
4) multi- parameters non-linearity control: This system for multi- parameters, when changes, the nonlinear system, take the computer as the control method, designs a set to have from seeks the stable security control system which the superior auto-adapted intelligent control, the function consummates
This central air conditioning dynamic load track energy conservation control system, with the central air-conditioning system necessary use, may realize the central air-conditioning system highly effective energy conservation, the effect is remarkable. After the theoretical calculation, compares with the permanent current capacity central air-conditioning system, whole year the average electricity saving rate may reach 20%-30%. This project technology content is high, is the collection warmly passes the air conditioning technology, the refrigeration technology, the intelligent control theory and the computer control technology is a body central air conditioning highly effective energy conservation system.
4. systems characteristics
1) entire closed loop: The central air conditioning main engine, the auxiliary engine, the circulatory system and so on took the whole constitution energy conservation control system, seeks one kind of best control rule, causes the central air conditioning main engine, the cold intermediary current capacity system all along with to shoulder Q the change to change, is for the purpose of satisfying the air conditioning area comfortableness to have to shoulder under the Q premise, realization overall system greatest degree energy conservation.
2) moves stably, safe: Optimized the main engine movement pattern, may solve the main engine to open stops the question, reduces the surge current, reduces the electrical network demand capacity; Uses softly opens stops with the low frequency movement water pump, the air blower, avoids opening stops attacks the electrical network and reduces the equipment machinery to wear, lengthens the useful life of equipment.
3) long-distance control: Through long-distance communication connection and computer connection, realization long-distance control, running status visible.
4) system adaptability strong: This electricity saving system may with the new clothing central air-conditioning system or with the old attire central air-conditioning system necessary use, does not change the original system the installment, the system connection is simple, the electricity saving system increase and the unloading cuts conveniently, does not have the impact. This system area is small, the overall system movement does not need to nurse, the low noise, not to have the unusual smell; Conserves energy, the environmental protection high is good; Does not produce the deleterious substance, not good has not affected to the environment. 空调节能技术的研究英文文献和中文翻译(7):http://www.youerw.com/fanyi/lunwen_17550.html
