1, there are differences between the two technologies:
Yaju series adopts 180 sine wave variable speed technology (which can meet various temperatures and save electricity), torque control technology (which can realize efficient operation) and efficient refrigerant heat dissipation technology (which can reduce the volume of heat dissipation module).
Free series adopts a new generation of DC frequency conversion technology (making the energy efficiency as high as 4.7) and weak magnetic control technology (improving the temperature adjustment ability and comfort).
2. Their functional characteristics are different:
Yaju series is a super-national first-class energy-saving product, which has the functions of energy-saving control, convenient maintenance, one-step troubleshooting and instant cooling/heating at home.
Free series has the characteristics of free combination (one outdoor unit can be matched with multiple indoor units), power saving, comfort, bass operation, flexible air supply/return, intelligence and simplicity.
3. The noise reducer used by the two is different:
Yaju series adopts noise-reducing motor for the external machine and patented high-efficiency noise-reducing volute for the internal machine.
Free series adopts outdoor electronic expansion valve to reduce noise, and the system can adjust the noise of the external machine by itself.
Extended data
Please pay attention to the following before purchasing central air conditioners:
1, determine the host model. It is necessary to consider the area and orientation of the house to see if there are large glass windows, so as to calculate the maximum simultaneous use coefficient of air conditioning.
2, determine the indoor unit and tuyere. Determine the model according to the actual cooling capacity. Each room or hall only needs one indoor unit or tuyere, which is about one per 12 square meter.
3. Determine the air conditioning layout. The location of the main engine should pay attention to good ventilation and heat dissipation, which is convenient for maintenance. At the same time, the location should be hidden as far as possible to avoid affecting the beauty of the house and the noise affecting the room. The location of the indoor unit should be coordinated with the interior decoration layout, and it is generally hidden in the ceiling or at the top of the high cabinet.
