Carrier service manual
The fluctuation range of motor rotor speed is within ±5 rpm and the motor can rapidly match the output of
DC inverter compressor. The efficiency is enhanced under
part load.
1.1.3 Newly designed sub-cooling heat exchanger
12°C sub-cooling degree makes the cooling capacity
increased efficiently. Innovative designed outdoor high
efficiency heat exchanger can reach up to 12°C sub-cooling
degree one time, reduces the system resistance and
improves reliability.
1.2 More flexible design
1.2.1 Wide capacity range
The outdoor units capacity range from 8HP to 72HP in 2HP increment. Maximum 64 indoor units with
capacity up to 130% of total outdoor units can be connected in one refrigeration system. Indoor units
consist of 11 types with more than 100 models, capacity range from 1.8kW to 45kW.
1.2.2 Wide operation range
The V4+ S series system operates stably at extreme temperatures ranging from -20°C(-4℉) to 48°C(118.4℉)
