Daikin central air conditioning FTZR236PC-W with nighttime sleep mode, the user can run after three hours of sleep, set the temperature drops 2 ℃, will be picked up one hour before 1 ℃, and promoting user sleep. The product also has an outdoor silent operation function, to ensure that the user during sleep without interference from the outdoor unit, bringing more quiet sleep environment. What is the role of central air conditioning? 1. The cooling function in the design and manufacture of air conditioners, generally allowing the temperature control between 16 ~ 32 ℃. When should the temperature setting is too low, while unnecessary power consumption, on the other hand cause central air quality indoor and outdoor temperature difference is too large, it can not adapt quickly out of the room temperature changes, susceptible to colds. 2. The air conditioner with an air conditioner dehumidifier dehumidifying action in the refrigeration process. People feel comfortable relative humidity should be around 40 to 60%, when the relative humidity is too large as more than 90%, even if the temperature is within the comfort range, people are still feeling poorly. 3. The heat pump heating and electric air conditioner has a heating function. Heating capacity with the outdoor ambient temperature decreases progressively smaller central air-conditioning company, can hardly meet the heating requirements if the temperature at -5 ℃. 4. Clean air in the air with a certain amount of harmful gases such as NH3, SO2 and other central air conditioning Which is good, as well as a variety of odor, body odor and odor, such as the bathroom smell. Air conditioner cleaning methods are: renewal wind, filtration, and the use of activated carbon adsorption or absorption of the photocatalyst. A, renewal wind: the use of moist indoor air blower system to outdoor volleyball, indoor formed a certain degree of negative pressure central air conditioning, fresh air into the room from all around the door, Chuang Feng, improve indoor air quality. B, photocatalyst: in the light irradiation can be regenerated, the adsorption (income) of ammonia, nicotine, acetic acid, hydrogen sulfide and other harmful substances freed, re-use central air conditioning central air conditioning manufacturers _ _ Sanyuan Xian Hao Electrical and Mechanical Xi'an Hao Electrical and Mechanical Technology Limited.
