Does frequency conversion air conditioning really save power? What should be paid attention to when using frequency conversion air conditioning
Four seas network: variable frequency air conditioning, one night only one electricity. We can often hear the slogan in advertisements. It sounds tempting. Can't help but ask if the variable frequency air conditioning really saves? In fact, whether the variable frequency air conditioning really saves power depends on the length of use. If the variable frequency air conditioner is opened for a long time, the power consumption of the constant frequency air conditioner is much smaller than that of the same time; however, if the opening time is not long and intermittent, it will not save power.
What should be paid attention to when using variable frequency air conditioner?
1. Variable frequency air conditioning can not work in the maximum cooling capacity for a long time. The maximum cooling capacity refers to the maximum cooling capacity that the air conditioner can achieve in a short time in a room with a specified area. When purchasing, the user should not take the maximum cooling capacity as the standard, but should determine the matching number of the selected variable frequency air conditioner according to the room area, and try to avoid the use of over area, which can not only avoid the damage of the air conditioner due to over load operation, but also give full play to its advantages of high efficiency and energy saving.
2. Outdoor unit of variable frequency air conditioner shall be installed in dry and ventilated place to avoid sun exposure and rain. The outdoor unit of variable frequency air conditioner is equipped with a microcomputer controlled frequency converter, and its circuit board is easy to be damaged in high temperature and humid environment. In case of automatic shutdown of outdoor unit after startup, shut down the unit as early as possible and inform the maintenance unit to repair as soon as possible, so as to avoid greater loss caused by fault expansion.
3. In daily use, do not set the temperature too low, so as to avoid the long-term high-speed operation of the air conditioner affecting the service life. It is better to set it in the automatic mode, so that it can not only refrigerate quickly, but also save electricity.
4. Whether the variable frequency air conditioner really saves power depends on the use time. If the variable frequency air conditioner is opened for a long time, the power consumption of the constant frequency air conditioner is much smaller than that of the same time; however, if the opening time is not long and intermittent, it will not save power. Because the energy efficiency ratio of the variable frequency air conditioner is very low when it operates at high frequency, and the rated energy efficiency ratio of the variable frequency air conditioner is lower than that of the fixed frequency air conditioner at present, the variable frequency air conditioner does not save electricity for the users who use it for a short time.
5. The room suitable for variable frequency air conditioning must have good airtightness, and there will be no frequent temperature fluctuations caused by human factors. Because the living room has a large area, a large number of people, many in and out times, and the room is not well sealed, therefore, the variable-frequency air conditioner that needs to operate at a lower frequency to save power often cannot make the room temperature stable near the set temperature due to these reasons, but must operate at a higher frequency, so as to achieve the purpose of power saving.
