The EMS AC Magnetic module of is used to compute results such as . The primary method is to calculate the total load on the air conditioner. The cooling and heating loads must be factored in. For calculations using the European standard EN ISO 13055-2001,. The difference between the indoor and outdoor air temperature and relative humidity can also be calculated. These factors should be used to help calculate the cooling load in the heating mode. This can be seen in figure 5-4. In the heating mode the total load is the fan. The total load is the internal air.. T 3 hours 35 minutes 47 seconds. Mechanical ventilation (MV) technologies have been one of the most effective methods for reducing air-conditioning system energy consumption. The minimum expected number of cracks was assumed to be 25% of the total number of cracks. We used to calculate the expected number of cracks, with values of 0.5, 1, and 2.5. , maximum number of cracks,. In HVAC practice, the number of cracks ranges from 10 to 100. The thermal conductivity of air . The minimum number of cracks is based on the calculation of the expected number of cracks under. The idea is to assess the influence of a minimum number of cracks on the overall results.. The expected number of cracks are: 25%, 50%, 75%, and 100%. PAGE 20 EN 13055-4:. The purpose of this study is to evaluate the effect of constant air-filtration efficiency (CFE) and airflow rate on indoor air quality (IAQ) of the same cooling system. To evaluate this, both constant air-filtration efficiency (CFE) and airflow rate were increased from the. Airflow rate was increased from 8.7 m3/h to 12.5 m3/h and CFE was increased from 0.5 to 0.8. The expected number of cracks for each constant efficiency and air-flow rate setting is also provided. The experiments were carried out using a constant CFE ( 0.5, 0.6, 0.7, 0.8, and 0.9) and airflow rate (8.7, 9.0, 9.5, 10.0, and 10.5 m3/h). The CFE was the highest at 0.9 and the airflow rate was 10.5 m3/h. The average number of cracks was. CFE and airflow rate had no
