How to design the central air conditioning project more reasonable?

Release time:2019-12-19 Clicks:123

Abstract】:Different from the simple installation of household air conditioning, because the central air conditioning is applied in a large area of space, if the whole space can be effectively covered by the cold air delivered by the air conditioning, it is necessary to go through planning and design before the project trial work, which central air conditioning project how to design reasonably?

Different from the simple installation of household air conditioning, because the central air conditioning is applied in a large area of space, if the whole space can be effectively covered by the cold air delivered by the air conditioning, it is necessary to go through planning and design before the project trial work, which central air conditioning project how to design reasonably?

Air conditioning basically helps the environment cool down by sending out cold air, so in the face of large area of space, it is a very important problem to calculate accurate and appropriate fresh air volume. Let's share the following design skills:

1. Generally, before the design, you can understand the different demands of different spaces for the fresh air volume. For example, in the shopping mall and non-smoking environment, each person needs 25 cubic meters of fresh air per hour, and so do other non-smoking office environment, gym environment, theater environment, etc. in a small number of smoking restaurants, the environmental demands are 30 Cubic meters, in a large number of smoking conference room environment demand is 60 cubic meters, non-smoking ward environment is 60 cubic meters.

If the environment where the central air conditioning is to be installed is the workshop space with production requirements, the design of the central air conditioning should also pay attention to the design of the compensated exhaust system, so as to ensure that a positive pressure state can be maintained in the internal environment of the workshop, and to ensure that each person in the factory has 30 cubic meters of fresh air per hour.

3. When designing, we should also pay attention to the adjustment of air, that is, to achieve five to eight air changes per hour, so as to ensure the comfort of the environment. According to this, we can get the value of circulating air volume. Air volume is the value obtained by multiplying the space volume and the number of air changes. After getting this value, we can get the value of fresh air volume by taking 10 to 15 percent 。
