Dunan Central Air Conditioning Manual
I. Instructions for the use of Dunan Central Air Conditioning 1. Pay attention to carefully adjust the temperature of the room temperature at a height of 1 ° C, and the temperature of the heating time is 2 ° C, which can save more than 10%of the power, and the human body almost not aware of the difference in temperature.2. Regularly clean the filter, the dust will block the filter mesh, reduce the effects of the cold and heat, and clean it once every half a month.3. Try not to open the doors and windows can reduce the exchange inside and outside the house, although the exchange inside and outside the house, which is conducive to saving power 4. Do not block the air outlet of the outdoor unit, otherwise it will reduce the heat and heat effects, waste power 5. Choose suitable air outlet angle, air conditioning is heavier than air, easySinking, the heating current is the opposite.Therefore, the air outlet is going up when cooling, and the downward is down, and the thermal effect is greatly improved.
How about Dunan Central Air Conditioning
Advantages: You can adjust the air outlet temperature switch of each inner machine according to the needs of the user, which can reduce the operating cost to the greatest extent.It can achieve three levels (0-70%to 100%) energy output according to the load to save energy.The way outdoor concentration is consistent with the surrounding environment.Using a new propeller fan, the contact between the airflow and the blades is smoother, reducing the noise caused by the vortex.The system has a fault self -diagnosis function and does not require professional maintenance to ensure operation safety.
