Central air-conditioning design and construction in particular need skilled technology, because design and construction is to measure the central air-conditioning installation effect, the use of an important guarantee. If the central air-conditioning design and construction is unreasonable, the later will appear a variety of problems, so the central air-conditioning installation environment can not be underestimated, central air-conditioning design and construction must have air-conditioning professionals. Huali electrical and mechanical has been the central air-conditioning installation, has 18 years of central air-conditioning installation experience in the design, construction team. Huali Electromechanical shares the key points of central air conditioning design:
First, calculate the cooling capacity
Refrigeration capacity is determined according to the refrigeration area, the enclosure structure, area, layer height, frequency of use, personnel density, indoor furniture and other factors will affect the determination of its refrigeration capacity. The amount of cooling required for a room can be accurately calculated according to the Heating Ventilation and Air Conditioning Design Specification, but this method is generally not desirable because it takes too long.Commercial design generally uses estimation method, that is, the cooling capacity Q s s - K, where in which S is the area, K is the unit area of cooling capacity, usually take 0.22 to 0.3KW \/m2 (for the south region), if the height is relatively high, it can be appropriate to take a larger value. Consumers can look at this number on the relevant data and then determine whether the design is appropriate or ask for reasons.
Second, choose outdoor models
The choice of outdoor machine model first look at the cooling capacity, the cooling capacity is large enough to meet the basic requirements of air conditioning comfort, to ensure that the machine can be used normally. Also to see the outdoor machine air-out form and outdoor machine size, because if some household-type air-conditioning outdoor machine placement size is small, we should pay attention to the size of the outdoor machine, distance from the wall to meet the ventilation requirements, and if the outdoor machine placement position on top of the cover, then choose a side wind model, in order to meet the heat exchange effect.
Third, the selection of air mouth
The size of the central air-conditioning air vent will affect the situation of the air, the situation of the air outlet directly affects the user's experience, so the size of the air outlet should allow the designer to do an accurate calculation to ensure that the air vent wind speed will not cause an uncomfortable user experience. In addition, the arrangement of the air vent also directly affect the cooling effect, the air outlet and return air and reasonable coordination can form a good convection of indoor air, giving people a better sense of comfort, in general, can be used side send back and down the way back. Owners can also ask designers to discuss a reasonable layout.
Four, noise
Noise value is a thing that has to be considered, if the whole set of air conditioners are designed and installed to find that noise is simply unacceptable, then all the work will become in vain. From the design, as the owner can clearly point out the use of each room, it is recommended that designers try to avoid outdoor machines placed nearby, to ensure that the noise does not affect themselves, and pay attention to the length of the airduct pulled by the indoor machine, because the longer the duct caused by the noise will be greater.
