What are commercial heat pumps?
Commercial ASHPs provide heating, cooling, and hot water to large buildings using ambient air heat and refrigerant cycles.
R410A remains widely approved, offering high efficiency and low maintenance; future HFO blends may follow but current systems perform well.
A cascade links multiple heat pump modules in stages, enabling high ΔT or wattage while maintaining efficiency.
Up to 16 monoblocks can be paralleled for scalable capacity beyond 5 MW.
Enhanced Vapor Injection increases heating output in sub-zero conditions by injecting mid-pressure refrigerant into the compressor.
Annual fan and coil cleaning, periodic filter checks, and scheduled refrigerant circuit validation.
Yes—dual-circuit control allows concurrent heating, cooling, and hot water loops.
With proper servicing, 15 years or more, typical for commercial HVAC equipment.
Sound power levels range 62–72 dB(A) per module, optimized with H-shape heat exchangers and variable-speed fans.
Three-phase 380–415 V 50 Hz, with breaker sizing per nameplate current specifications.
