How much electricity does a 1.5-hp air conditioner need to work for 10 hours a night

When the indoor temperature reaches the preset temperature, as long as the outdoor compressor and electric fan stop running, the indoor cabinet electric fan will continue to operate. Therefore, the indoor cabinet electric fan wind speed is set to active mode, and the air conditioner The fan speed will be adjusted automatically according to the indoor temperature. When the indoor temperature reaches the preset temperature, the fan will be adjusted to low-speed operation.

　　 If you continue to turn on the air conditioner for ten hours a day, the power of the air conditioner is turned on for ten hours, but the time for the compressor of the air conditioner is not that much. For example, when the outdoor temperature is relatively low, the air conditioner compressor has less time to run. When the cooling temperature you set is relatively low, the operating time will be relatively long. When your room is sealed better, the air conditioner saves electricity. Therefore, the detailed operating time of the air conditioner is not always certain. Of course, when the external conditions are opposite, the power consumption of a 1.5-hp air-conditioning compressor is 1.5 times that of a 1-hp air-conditioning when the compressor runs in the opposite direction.

　　 The power consumption mainly depends on the power of the compressor. Because the calculation method of single-point energy efficiency ratio of fixed speed air conditioner is commonly used, so: compressor power = refrigeration capacity / energy efficiency ratio. According to the current production level, the energy efficiency ratio of ordinary air conditioners is between 2.6 and 3.4. The energy efficiency ratio of the air conditioner can also be obtained by dividing the input power of the air conditioner (on the nameplate) by the input power. Because when the air conditioner is running, after reaching the preset temperature, the outdoor unit (ie compressor, fan) of the air conditioner will feel the signal through the temperature controller lost by the air conditioner computer motherboard, and instruct the outdoor unit to stop running, of course, when After the indoor temperature exceeds our preset temperature, the outdoor unit of the air conditioner will also feel the signal through the temperature controller that is missing from the computer motherboard of the air conditioner, and instruct the outdoor compressor to perform cooling tasks. So when we turn on the air conditioner, we habitually preset the temperature at low, which actually prolongs the operating time of the air conditioner compressor. The longer the air conditioner compressor task time, the more power consumption will increase accordingly. Therefore, it is best to preset it at 28°C when starting up. When the room reaches 28°C and the air conditioner runs for a duty cycle, we gradually increase it according to our needs.

　　 Generally speaking, the cooling capacity of a horse of air conditioner is roughly 2000 kcal, which should be multiplied by 1.162 (1K=1.162W) when converted into an international unit. Therefore, the cooling capacity of one horse should be 2000 kcal×1.162=2324 watts. Of course, different air conditioners have different cooling performances. The cooling capacity of one horse is about 2300W～2500W. (W) means refrigeration capacity, so the refrigeration capacity of 1.5 horses should be 2000 kcal×1.5×1.162=3486(W), and so on.

　　 Based on this, the number of horses of the air conditioner can be roughly determined based on the cooling capacity. Under normal circumstances, 2200 (W) ~ 2600 (W) can be called 1 horse, 4500 (W) ~ 5100 (W) can be called two horses, and 3200 (W) ~ 3600 (W) can be called 1.5 horses.
