R410A Tropical Split Type Technical Manual
1. Fixed model that diffuses air at a 360 angle.
2. The outline size should increase when the air volume is over
350CMH. (For above 303), i.e., when about 9 diffusers are required,
the outline size should increase.
3. The diffuser pipes should preferably have the same length after
branching, and the minimum length of the ventilation pipes is 5m.
1. Fixed model that diffuses air at a 360 angle.
2. The outline size should increase when the air volume is over
350CMH. (For above 303), i.e., when about 9 diffusers are required,
the outline size should increase.
3. Proper air speed: For air speed of over 2-3.5m/s, select other
diffusers (with great noise).
4. Install the diffuser pipe if it is necessary to install the model of over
3.5m/s.
5. For purpose of cooling-only model.
1 The lengthwise adjustable model which diffuses air at a 360 angle.
2. With the change of the cooling/heating air flow, the horizontal and
vertical distance of the fan can be adjusted (applicable to department
store and exhibition hall where the decorative effect is essential).
1. Low noise compared with other air outlets. Applicable to tall
buildings that require along distance of air conditioning.
2. Select the ventilation pipe connection caliber according to the
distance and the air speed.
3. Applicable to storey height of over 5m (for design of tall storey such
as temple, consult Midea).
1. The fan is the adjustable type which can change direction of air
flow. It is used for deluxe decoration.
2. The outline size should increase when the air flow is over 450CMH
(3 or 4 SOLT) when about 6 diffusers are required, the outline size
should increase.
3. If the proper air speed is 2.5-5m/s and actual air speed reaches
over 5m/s, it is necessary to choose other diffusers (with higher noise
values).
1. Low noise compared with other air outlets. Applicable to tall
buildings that require a long distance of air conditioning.
2. Select the ventilation pipe connection caliber according to the
distance and the air speed.
3. Applicable to storey height of over 5m (for design of tall stores such
as temple, consult Midea).
