What is the GLHP heat pump
A heat pump for commercial buildings such as offices, shops and hotels: heating in winter and cooling in summer. 50 and 75 kW models.
How the GLHP heat pump works
The Hitachi inverter compressor adjusts its output to the building load, and heat from the outdoor air is transferred to the heating system water. In summer the unit works in reverse and chills water for fan coils.
GLHP heat pump: advantages
- Operates at outdoor temperatures from −25 to +45 °C
- Seasonal efficiency SCOP up to 4.66 at 35 °C
- Heating and cooling in one unit
- Hitachi inverter compressor, natural R290 refrigerant
