How to buy an air conditioner regulator?
In the hot summer, the frequency of use of many home appliances will be higher, such as refrigerators, air conditioners, etc., and this time due to peak electricity consumption, there will be many places in the external network voltage is lower, there may be no way to start the air Situation, at this time, many families will think of using air conditioner regulators. So, are air conditioner regulators useful? How to buy an air conditioner regulator?
Are air conditioner regulators useful?
Unless the grid voltage is extremely low, the transformer is generally very effective. Current regulators generally have a voltage regulation function, which can be adjusted to 220V. As for the brand and price, it's hard to say. You can go to the home appliance market and compare it. But first of all, it must be determined that the voltage is too low. If it is determined that the voltage problem can be solved by installing a voltage regulator. The role of the voltage regulator is to stabilize the voltage that is too high or too low at 220V. The voltage stabilizer should be selected according to the power of your electrical equipment. A voltage stabilizer greater than the rated power of your home air conditioner (marked in the air conditioner manual) can be selected to ensure the normal operation of the air conditioner. The price of voltage regulator is that the greater the power, the more expensive.
How to buy air conditioner voltage stabilizer?
1. Calculate the power of the voltage regulator: The main load of the air conditioner is the compressor, so it belongs to the motor type load. The current of the motor is very large when it is instantaneously started. Although many air conditioners are started by frequency conversion, the current is still very large If the air conditioner is 2KW, if the air conditioner is 2KW, it is better to match the 3KW power with a 6KW regulator. How to calculate the power of the air conditioner, the general air conditioner has 1P, 1.5P, 2P, 3P, 1P = 0.75KW, everyone can do according to this calculation.
2. The power factor of the voltage regulator, 80% of the voltage regulators currently on the market are 0.7, and the power factor of the 20% voltage regulator is 0.8. What does it mean? It is a 10KVA voltage regulator, the actual output power x 0.7 = 7KW
3. When using the voltage regulator in summer, most of them are due to the low external network voltage, so pay attention to the work margin when selecting the voltage regulator. In general, the actual load should not exceed 80% of the power of the voltage regulator. Why?
Let's calculate it and know that when the external network voltage is 220V: 6000W / 220V = 27A (current), when the external network voltage is 170V: 6000W / 170V = 35.3A (current), after comparison, you can see that the current is low when the input voltage is low The larger, and the wire diameter of the transformer in the voltage regulator is fixed, the current withstand at a low voltage is much larger.
4. Calculate according to the above method: 2KW air conditioner X2 times = 4KW, where the air conditioner power is multiplied by 2 because the air conditioner compressor's instantaneous starting current is large; 4KW / 0.8 = 5KVA (regulator power), here divided by 0.8 is placed stable The working margin of the voltage regulator is 5KVA / 0.8 = 6.25KVA (the power of the regulator needs to be purchased), where dividing by 0.8 is the actual load capacity of the regulator is only 80%. That is, the 2KW air conditioner with 6KVA regulator is calculated in this way.
In fact, when the voltage of the external network is unstable, we use the air conditioner regulator is very effective. As for the air conditioner regulator, many friends may not understand it very well. Of course, generally speaking, the price of the air conditioner regulator may be higher than that of the transformer. For economic families, it may be better to choose an air conditioner transformer.
