The higher the outlet water temperature of the air source heat pump heating unit, the better

Some users unilaterally pursue the heating effect, and will increase the outlet water temperature of the air source heat pump. We know that in general, the outlet temperature of the air source heat pump is ideal at 41°C-45°C. If the water temperature of the air source heat pump heating unit is increased unilaterally, the energy saving effect will be worse. It is calculated that for every 1°C increase in the outlet water temperature of the air source heat pump heating unit, the heating capacity will decrease by 1% to 2% accordingly. In the case where the walls, doors, windows and other conditions surrounding the building space are similar, the higher the water supply temperature of the air source heat pump, the energy efficiency of the air source heat pump will decrease, and the power consumption of the air source heat pump heating system will also follow. Increase.

Different heating ends have different heat dissipation capabilities, and the water temperature required to achieve the same effect is also different. When the ground heating is used as the end of the air source heat pump heating system, its requirements for the water temperature of the air source heat pump are lower than that of the radiator as the end, and the temperature difference between the two may reach 10 ℃.
