1) The inverter air conditioner starts running at high power and quickly reaches the set temperature. The low power is maintained and the room temperature is balanced. Therefore, the cooling and heating are rapid, the power is saved, and the room temperature fluctuation is small.
2) The fixed-frequency air conditioner operates at a fixed power, and the indoor temperature is maintained by frequent switching machines. Therefore, the cooling and heating speed is slow, and the impact on the home power grid is large, and the room temperature fluctuates greatly.
3. Representation of air conditioning model:
The domestic air conditioner naming method is as follows: KFR (d) 5000LW / T (D BP JXF) K - air conditioning F - split type R - heat pump heating type D - auxiliary electric heating 5000 - cooling / heating capacity L - structure type W - outdoor Machine T-development model D-DC BP-frequency conversion J-ion dust removal X-two-way air change (L-structure type code: "L"-cabinet type, floor type; "G"-wall type; C"-window type ; "N" - built-in; "F" - duct type; "Q" - embedded; "D" - ceiling type)
4. Cooling capacity / heating capacity of air conditioner:
1) When the air conditioner is performing the cooling operation, the amount of heat discharged from the enclosed room per unit time is called the cooling capacity of the air conditioner.
2) When the air conditioner is performing heating operation, the amount of heat released from the enclosed room per unit time is called the amount of heat generated by the air conditioner.
3) 150W cooling capacity per square meter of air conditioning: thus the calculation formula for the use of air conditioning in the room area:
Cooling capacity /150W=â–³ â–³+2=â–¡ â–³-2=0
“△†means adapting the area of ​​the room “□†to adapt to the maximum area “0†to adapt to the minimum area. For example: KFR-2601GW/BP Cooling capacity: 2600W 2600/150=17 17+2=19 17-2=15
That is, the applicable area of ​​the air conditioner is 15-19m2, and the number of air conditioners is also derived from this.
Classify air conditioners based on cooling capacity:
1P: 2300W-2500W1.25P: 2600W-2800W 1.5P: 3000W-3600W
2P: 4000W-5200W 3P: 6500W-7200W 2.5P: 5800W-6200W
5P: 12000W 10P: 24000W
power consumption:
1P: around 770W 1.5P: around 1300W 2P: around 1800W
3P: 2800W or so 5P: 5000W or so 10P: 10000W or so
General air conditioning voltage is 220V, 3P has 220V and 380V; 220V is suitable for household use; 380V is power for commercial use
Generally 5P, 10P are commercial machines, the code of 380V is generally: "3", "S"
Air conditioning area:
1P: 8-12m2 1.25P: 12-18m2 Small 1.5P: 14-22m2 Large 1.5P: 16-24m2 2P: 23-34m2 2.5P: 27-42m2
3P: 32-50m2 5P: 46-70m2 10P: 150m2 or more
