Method for determining the number of environmental friendly air conditioning units in Keruilai

Release time:2023-07-24
Reading volume:124

  The number of Keruilai environmentally friendly air conditioning units is determined by the cooling capacity and the number of air changes. It is also generally related to the local climate and the environment of the day. Below, I will give you a list of methods for estimating the number of air changes.

  Number of units used = total indoor volume * number of air changes / actual air volume of a single air conditioner

  The estimation method is that for some buildings that are not very demanding, in order to avoid the trouble of calculation, according to the basic design conditions of the indoor and outdoor design temperature difference of 5-8 degrees, the number of air changes in different areas can be roughly estimated and selected. Environmentally friendly air conditioners The specific number of air changes is as follows:

 

Kerilai environmentally friendly air conditioner

 

  1. Dry and hot area: The overall climate characteristics of this area are mainly drought, low relative temperature, the average relative humidity of the entire work area is less than 40%, high salinity, large area of ​​high temperature and strong solar radiation. The highest daytime temperature can reach 47 degrees, and the wind is usually very strong at noon and afternoon, triggering sandstorms, a common climate feature in the local afternoon. In this situation where central air conditioning cannot solve the problem, the evaporative air conditioner is an ideal cooling and humidifying product. When using Keruilai evaporative environmentally friendly air conditioning products, the air exchange times are as follows:

  The general environment ventilation frequency is 15-18 times/hour;

  18-24 times/hour in crowded public places;

  Production workshops with heating equipment 24-30 times/hour

  30-36 times/hour in high temperature or severely polluted workshops.

  2. Hot and humid areas: This area is mainly along the coast. Its main climate characteristics are high annual average temperature and relatively stable humidity. A hot and humid climate, in addition to affecting human fitness, promotes the growth of mold and fungi. However, the economy of this area is relatively developed, and various processing factories are numerous and dense. In particular, energy-saving and environmentally friendly evaporative air conditioners are needed to strengthen ventilation and modify the workshop environment. When using it, choose Keruilai evaporative environmentally friendly air conditioners. The ventilation frequency is as follows :

  The general environment ventilation frequency is 25-30 times/hour;

  30-40 times/hour in crowded public places;

  Production workshops with heating equipment 40-50 times/hour

  50-60 times/hour in high temperature or severely polluted workshops.

  3. Warm and hot areas: Compared with hot and humid areas, this area has slightly less rain. The summer temperature is around 34 degrees and the relative humidity is around 50%. The ventilation frequency selection when using Keruilai environmentally friendly air conditioners is as follows:

  The general environment ventilation frequency is 20-24 times/hour;

  32-40 times/hour in crowded public places;

  40-48 times/hour in high temperature or severely polluted workshops
