What is the energy-saving transformation of central air conditioning? My hotel owner wants me to know about it, and wants to transform the central air conditioner of the hotel to save electricity.

The energy-saving transformation of central air conditioning is mainly considered from the following aspects:

1, reducing the energy consumption of circulating water pump motor.

The circulating water pump in the central air conditioning system consumes a lot of electricity, accounting for 15-30% of the whole air conditioning system, so the energy saving of the water pump is very important and has great energy saving potential.

2. Reduce the power consumption of wind turbines.

The fans in the central air conditioning system include air conditioning fans and exhaust fans. The power consumption of these devices accounts for 75% of the power consumption of air conditioning systems, so their energy potential is the greatest. Intelligent variable frequency fan is used to change constant air volume control into variable air volume control to reduce wind speed and noise, and the terminal fan is changed into variable air volume control system, which can automatically adjust the air supply volume of air conditioning according to the changes of air conditioning load and indoor demand parameters, adjust the air supply temperature when the minimum air supply volume is reached, and minimize fan power to save energy. There will be no supercooling or overheating indoors, and the air conditioning load can be reduced by about 5-30%.

3. The water system adopts variable flow fuzzy control frequency conversion energy-saving technology.

In the central air conditioning system, the capacity of cooling water pump, chilled water pump and cooling tower fan is selected according to the maximum design heat load of the building, and the margin is 10- 15%. Throughout the year, the system works under a fixed maximum water flow for a long time. Due to the constant changes of seasons and day and night loads, the actual heat load of air conditioners is much lower than the design load most of the time.

4. Use intelligent control system

At present, most central air conditioners are not equipped with automatic control of air conditioners, and their equipment is put into operation manually. This makes the operation and management of air conditioning system extremely inconvenient and the energy consumption is greatly increased. If the intelligent automatic control system of air conditioner is installed, even the simplest start-stop control can greatly save the energy consumption of air conditioner and set the terminal temperature of air conditioner easily and flexibly.
