1. Project Overview
Location: Central Hungary real estate
Timeline: June 2024 – June 2025
Equipment: R290 12 kW three‑phase air‑source heat pump
Application: Residential
2. Customer Requirements
Reliable Low‑Temperature Performance: Continuous operation throughout Hungarian winter (–10 °C to 0 °C)
High Energy Efficiency: Maintain strong COP under sub‑zero conditions
Eco‑Friendly Refrigerant: Fully compliant with EU F‑Gas regulations, minimal GWP
Three‑Phase Integration: Seamless connection to existing 400 V power infrastructure
3. Solution Delivered
Heat Pump Selection: Fourth‑generation monoblock using R290 (GWP = 3), nominal heating capacity 12 kW, rated COP 4.1 at A7/W35
Electrical & Controls:
Three‑phase 400 V input with soft‑start VFD to reduce inrush current
Integrated smart controller offering remote monitoring of temperatures, operating hours, and fault alerts
4. Customer Testimonial
“After one year of operation, the R290 unit has proved exceptionally reliable—even in sub‑zero temperatures. Its energy savings have already paid for half the system cost, and the switch to a low‑GWP refrigerant aligns perfectly with our sustainability goals.”
