Low Ambient VRF Air Conditioners
Johnson Controls has developed Variable Refrigerant Flow (VRF) air conditioners.
Johnson Controls currently introduces a Low Ambient VRF Heat Pump Outdoor Unit that realizes highly-

scroll compressor and improving defrosting function.
High Heating Performance
Ŷ Provide 100% Heating Capacity Even Under Low Ambient Temperature Conditions
High heating operation is available under the ambient temp. up to 15
o
F (-10
o
C). Also even under the
ambient temp. up to -13
o
F (-25
o
C), maintain stability for the heating operation.
High heating capacity is 1.5 times higher (6RT: -4
o
F (-20
o
C)) than that of our standard VRF.
