Haha! Domestic models: FP3.4--1.8, FP5.1--2.8, FP6.8--3.2, FP8.5--4.0, FP10.2--5.6, FP13.6--7.1, FP17.0-- 9.0, FP20.4--9.8, FP23.8--11.0, haha, this is my experience value, the manufacturer's standard is higher than this, but I think the manufacturer's standard is full hot and full cold! We choose to follow sensible heat and sensible cold!
It is a limited space. The wind power tower is a limited space, because the limited space at the first level of the wind turbine refers to the space that requires special attention when maintaining and inspecting the wind turbine. These spaces are often not suitable for long-term stays and activities, and may involve working at heights or have dangerous factors. Safety measures such as ventilation and prevention of slipping and climbing need to be paid attention to in wind power towers. So it is a limited space.
