Central air conditioning chiller is a large refrigeration equipment, very power consumption, so how to save energy? The operator should understand the working principle and characteristics of the unit and the entire air conditioning system, and strictly operate according to the operating instructions of the refrigeration unit to ensure the safe operation of the unit. So, how does the central air conditioning chiller achieve energy saving? Below and central air conditioning maintenance Xiaobian together to learn about it!

There are many ways to save energy, in addition to operation, there are management problems.

First, the outdoor temperature is low in the summer morning, while the air is fresh and the indoor temperature is high, the new fan of the air conditioner and the fire exhaust system can be used to pump and supply air for about 15 minutes. This practice has the following benefits:

1. Before starting the machine, the room temperature can be lowered and the load of the host can be reduced.

2. Improve indoor air quality.

3. Check whether the smoke exhaust system is normal, which is conducive to fire fighting.

Second, always grasp the specific situation of each cold occasion, timely open and close the relevant air cabinet, fan coil and other equipment, in order to reduce the heat load of the system, in fact, can reduce the energy consumption of the unit. Power consumption of the terminal device.

Third, according to the changes in temperature and cold occasions, the chiller should be turned on or off at the appropriate time. Under the premise of meeting the requirements of air conditioning, the chiller should be turned on or off as little as possible, and the running time of the chiller should be reduced as much as possible.

Fourth, find out the actual situation of the whole cold situation, master the good start and stop time, especially the time of pumping circulating water with the freezing pump, the time of each system is different.

5, pay attention to close all doors and Windows leading to the outside to prevent cold leakage and outdoor hot air intrusion. Especially for buildings with south-facing doors, we should try to prevent hot air from entering (because of the southerly wind in summer).

In summer, when the temperature is high at 4 p.m. every day, we should pay close attention to the operation of the unit and adjust the operation of the unit in time to avoid increasing the unit before the indoor temperature rises. Significantly elevated and high heat load, easy to damage equipment and increase energy consumption. After adding the unit, please pay attention to the observation results, when the return water temperature of the frozen water drops to a certain extent, the increased unit should be immediately closed (including the corresponding refrigeration pump, cooling pump, cooling tower fan and water inlet and outlet valve), in order to prevent power waste, the centrifugal unit should pay more attention to low load surge.

From 7 p.m. to 9 p.m., the heat load of shopping malls, entertainment venues and other places is also very large, mainly because shortly after dark, the sun radiates to the ground during the day, the heat dissipation of the external wall, and the increase of customers and visitors, resulting in the temperature increase in cold occasions, at this time should also adjust the operation of the unit.

Seven, pay attention to the quality of chilled water and cooling water, and do a good job of water treatment. Regularly check and supervise the work of the water treatment company to ensure that there is no scale and dirt in the condenser and evaporator, so as not to affect the heat exchange effect of the condenser and evaporator, and increase the power consumption of the main engine.

8. Pay regular attention to central and local weather forecasts, have a clear understanding of daily temperature changes, make clear targets for air conditioning work, and pay more attention to climate change in coastal areas where typhoons often occur.
