Modular Low Temperature Air Source Heat Pump Central Heating
Modular Low Temperature Air Source Heat Pump
Features:
1. Low temperature and high efficiency: ambient temperature -12 °C, outlet temperature 45 °C, energy efficiency ratio ≥ 2.4, ambient temperature -20 °C, outlet water temperature 45 °C energy efficiency ratio ≥ 2.0, comprehensive energy efficiency is higher than Chinese energy conservation certification;
2. Low ambient temperature and high water outlet temperature: ambient temperature -25 °C, the outlet temperature can be as high as 60 °C;
3. Stable and reliable: ambient temperature ≥ 43 °C, water outlet temperature 60 °C, ambient temperature -25 °C, water outlet temperature 60 °C, long-term stable operation;
4. Water route cleanliness: the unit water route and the water side heat transfer water route adopt the full copper design, nowhere to rust, to ensure that the water quality is not affected by the unit pipeline;
5. Advanced technology: dual electronic expansion, 3-way fin temperature sensor, optional humidity sensor to control defrosting;
6. Modularization: modular design allows for free expansion, facilitating investment in phases
