Air conditioning unit performance optimization measures In order to ensure that all types of air conditioning units, fan coils can fully play their performance in operation, to meet energy, environmental protection, comfort and other requirements, designers should cooperate with the manufacturer to make product selection and Match work. There are mainly the following aspects: accurate system calculation, reducing fan energy consumption and noise, and improving the operation stability of the air-conditioning system cause the unstable operation of the air-conditioning system, most of which is caused by improper selection of air-conditioning equipment. To solve this problem, we need to accurately calculate the air volume and system resistance loss of the air conditioning system. At the same time, the equipment manufacturer should assist in the equipment selection according to the cold load, the loss of pipeline resistance and the place of use, or separately determine the air cooler and fan of the air conditioning unit according to actual needs.
High-efficiency and low-noise fans are selected. At present, there are many wind turbine manufacturers that are compatible with air-conditioning equipment in China. The performance of the wind turbines is different. To ensure that the fans are operated in an efficient and low-noise state, it is recommended to establish a wind turbine information base and then perform the performance of different types of wind turbines. The curve is fitted, and the computer can select the fan with the highest efficiency and the minimum power required in the model. Then compare the different types of fans to optimize the selection of the fans. The balance and size of the fan and pulley are determined. The pulley drive of the fan is used in a large number of applications in the combined air conditioner. However, the selection of the pulley has not yet attracted the attention of the design and manufacturing units.
At present, the wind turbine manufacturer balances the impeller of each fan, and the dynamic balance of the pulley is often neglected, which makes the combined air conditioner often have vibration and bearing damage, which affects the normal operation of the air conditioner. Therefore, it is recommended that the wind turbine manufacturer should perform a dynamic balance test on the pulley. The correct use of the forward multi-wing fan has the characteristics of high wind pressure and small size. Therefore, under the same size conditions, it has the advantages of low rotation speed and low noise. Most of the combined air conditioners provided by foreign manufacturers are equipped with forward multi-wing type fans, which are currently widely used in domestic air conditioning systems. Since the characteristic curve of the forward multi-wing type fan is not the same as that of the backward vane type fan, attention should be paid to the design. Therefore, when using a forward multi-wing type fan, the designed air volume and wind pressure should be as accurate as possible, and it is not appropriate to blindly increase the safety factor, which is more important than the backward blade type fan.
Improve the structure of the air-conditioning unit and reduce the air leakage rate According to the national standard, when the static pressure of the combined air conditioner is 70Pa, the air leakage rate of the unit should not exceed 3%. According to foreign data, the air leakage rate is 10%, and the fan shaft power Increase by 3%; thus, it can be seen that reducing the air leakage rate is an important condition for ensuring energy-saving operation of air-conditioning units. However, the air leakage phenomenon of the domestic combined air conditioner is generally serious. The air leakage point is generally in the four corners of the unit, the bottom plate, the functional section connection, etc. The main reason is that the unit structure design is unreasonable, the sealing material quality is poor, and the site installation is not Pay attention to balance and so on. Excessive air leakage rate not only affects the temperature and humidity requirements in the room, but also increases the power consumption. The air conditioning unit is one of the important components of the centralized air conditioning system. To fully utilize its performance and meet the requirements of energy saving, environmental protection and comfort, it is necessary to cooperate in design and manufacture.
The power of ordinary household electric iron is generally 300W, 400W ,500W,800W and 1000W .
Its power specifications are 300W, 400W,500W, 800W and 1000W, and the temperature control range is 60-230 ℃. The electric iron is internally equipped with a bimetallic temperature regulating switch, which automatically cuts off the power supply when the specified temperature is reached; When the temperature is lower than the specified temperature, the power supply is automatically turned on for heating. The names of various ironed fabrics are marked on the temperature control knob. When the knob stops pointing to the name of a fabric, the iron will control the temperature within the appropriate greenhouse range for ironing the fabric, which can meet the ironing requirements of nylon, synthetic fiber, silk, wool, cotton, hemp and other fiber fabrics.
