With the increasing industry, electricity has become an important issue for enterprises nowadays. Together with the lack of water resources, saving electricity has become the slogan of enterprises. How do industrial machinery and equipment such as industrial air conditioners, freezers, and cooling towers save energy and save electricity?
The first measure: How to control the humidity in the air-conditioned area is more economical?
In order to meet the air conditioning temperature of direct production demand, in cooling, the upper limit of the specified temperature should be controlled as much as possible. The temperature and humidity should be adjusted according to the season change. The air conditioning temperature in the office area should be controlled at around 26 °C. In terms of system, the temperature is increased by 1 °C, which can save about 6%.
The second measure: What is the temperature difference between the chilled water inlet and outlet, and the freezer zui power saving?
Under normal circumstances, when the temperature difference between the chilled water inlet and outlet is controlled at 4 - 5 °C, the freezer operates in the high efficiency zone. However, when the cold load is low, the temperature difference will be reduced. At this time, the operating conditions of the freezer should be adjusted, or the frozen water meteor should be adjusted.
The third measure: How to save electricity for the cooling pump?
For the conventional cooling water pump, when the temperature difference between the inlet and outlet of the cooling water is less than 4-5 degrees, there will be a phenomenon of “small temperature difference, large meteor”. At this time, the pump does some useless work, and the pump is controlled by frequency conversion or replaced by a small pump. Large pumps can save a lot of power.
The fourth measure: Why is the variable speed adjustment effective measures for pump power saving?
According to the relationship between pump flow Q, pressure P, number of revolutions n and power N: it can be seen that the adjustment of the speed can greatly adjust the operating power of the pump. Pump power saving is mainly to adjust the power consumed by the pump under the premise of meeting the required flow head, and can not be adjusted by throttling. Compared with other adjustment methods, the variable speed adjustment not only ensures that the pump runs in the high-efficiency zone, but also has high efficiency and low energy loss, and can flexibly adjust the running power of the pump according to different requirements, so that the pump can consume the demand if it meets the demand. The electric power zui matches, zui power saving. At the same time, it is also a common and effective measure used in pump power saving.
Fifth meter: How to control when the cooling water pump is running in parallel?
When the cooling water pump is not in the form of one-to-one, but in parallel, the number of pumps running should be controlled according to the temperature difference between the inlet and outlet of the cooling water. Several parallel pumps are matched in size, and the pumps of different specifications are operated according to the demand load. Electric, Zui is good for water pump frequency control, the effect is particularly good.
Sixth: In the non-high temperature season, how does the cooling tower operate to save electricity?
In the non-high temperature season, that is, in the winter and transition seasons, the cooling tower fan load is small, and the outdoor ambient temperature is low. Under normal circumstances, no forced cooling is required. Therefore, the cooling tower fan can be turned off or its frequency conversion control can be performed according to actual conditions.
Seventh: How to play the cold storage function of the freezing pool?
The main function of the general freezing pool is to buffer and replenish water. Some systems have no pool and only a small expansion tank. In the case that the capacity of the freezer has a margin, and the freezing pool can have a certain capacity, the peak-to-valley electricity price difference can be utilized, and several freezers are operated at full capacity during the valley electricity period, so that the pool has a lower temperature of chilled water. The cold star stored in the pool is released during the peak power period to reduce the load on the freezer, which can save a considerable amount of electricity.
Eighth meter: How to consider the function of the freezing pool when building or rebuilding?
When it comes to the construction or expansion of industrial air-conditioning systems, consideration should be given to giving full play to the function of the freezing pool. First, consider the larger-capacity underground water pool, which can be greened above the pool, followed by the valley storage, and then as part of the fire. Features such as pool. This will not only save a lot of investment, but also save some air-conditioning operating costs.
The ninth measure: What are the advantages of the cold storage pool?
It saves electricity, has low investment, short payback period, low operating cost, acts as a fire pool, regulates cold load, and runs smoothly on the freezer.
Tenth: Why is the power saving potential of industrial air conditioning systems greater?
Because the air conditioning system is designed based on the data of the load, in the normal operation, the large load of zui accounts for a small share of the total load of one year, that is, most of the time is running in the low load zone, once the system is in operation After installation and operation, the water system and the wind system will be fixed, and it is impossible to change with the demand load. The pump fan and other equipment will always operate according to the original conditions. When the demand load is low, the phenomenon of “l(fā)arge horse-drawn carriage” will occur. Therefore, the air conditioning system has a large potential for saving electricity.
The eleventh meter: What should I do if there is a heat source in the air-conditioned area?
If there is a large heat source in the air-conditioned area, it will definitely increase the demand for cold load. If the heat source cannot be eliminated, reducing the heat generated by it is the main way to reduce the air-conditioning load. Local exhaust, post supply, and isolation from the surrounding are all effective measures.
Twelfth meter: Why should the air conditioning system be cleaned?
The cleaning of the water system mainly includes the cleaning of the condenser, the evaporator, the coil, the cooling tower and other heat exchangers. When the water system is operated for a certain period of time, impurities, oil and the like are adsorbed on the inner and outer surfaces of the heat exchanger, so that the heat exchange The heat exchange capacity of the device is reduced, and the energy efficiency of the refrigerator is reduced and the output is insufficient. Regular cleaning of the heat exchanger can improve the heat exchange capacity, improve the energy efficiency and output of the freezer, and also extend the service life of the equipment.
The thirteenth meter: Why should the air system of industrial air conditioners be cleaned?
The wind system mainly includes air-conditioning boxes, fans, coils, filters, condensate pans, tuyères, etc. After running for a certain period of time, these devices have more surface area, resulting in lower heat exchange capacity, increased resistance, microbial bacteria, polluted air, etc. . After cleaning the air system, it can not only reduce system resistance, improve heat exchange capacity, save electricity, but also reduce air pollution, improve air quality and be healthy.
Fourteenth: How to solve the hydraulic imbalance?
Due to the lack of pressure regulating devices, the hydraulic system will cause partial imbalance of water pressure in the system. In order to ensure the demand, the lift of the pump has to be increased to overcome the large resistance of the system and increase the power consumption of the pump. If a pressure-balanced device is added to the pipe that produces the hydraulic imbalance and adjusted, the lift of the pump can be reduced, thereby reducing power consumption.
