For a customized central air-conditioning system, resulting in poor system effects, large energy factors not only in the central air-conditioning equipment installation, more because of the system that appears in Xi'an, central air-conditioning installation. Points: 1, central air-conditioning energy factors - when room design cooling load calculation is not accurate 2, central air-conditioning energy factors - load accurately calculate room central air conditioning, but the selection of inappropriate 3, the impact of central air-conditioning energy factor - Installation No air conditioning and heating according to the construction norms how many degrees the most appropriate - every 2 ℃ lower than 10% on energy saving 1. winter air temperature setting down every 2 ℃, air conditioner can save more than 10%. From the energy point of view the production of central air-conditioning, air-conditioning set temperature in the heating situation to ensure that the human body, of course, the lower the better. Therefore, a comprehensive variety of factors, the proposed winter air temperature is set to be appropriate at about 20 ℃. 2. In addition, because warm air is lighter than air, easy to float over the entire closed room, the use of wall-mounted air conditioner, it is preferable to adjust downward angle outlet, which could power.
