Air conditioning and thermal comfort:
Each air conditioning system for indoor comfort (Thermal comfort) includes 4 main parts for control, which by controlling the above 4 parameters can be expressed that a space is equipped with air conditioning system.
- Temperature
- Humidity
- Fresh Air
- Air Distribution System
Temperature:
The first parameter to control the room space is the temperature measured by the thermometer (TDB). As you know, the temperature measured by a thermometer or thermometer must be away from any heating device or direct sunlight and تا in order to be able to measure an integer. The standard indoor temperature in the optimal conditions in summer is 77 to 81 degrees Fahrenheit and in winter conditions is equal to 64 to 72 degrees Fahrenheit, for the indoor space.
Humidity:
The amount of moisture or the moisture parameter is essentially the same as the relative humidity. Suitable range for humidity is 50-60% for summer conditions and 45-60% for winter conditions.
Note: The greater the difference between dry bubble temperature (TDB) and wet temperature (TWB), the lower the relative humidity and
The smaller the temperature difference between the dry and wet bubbles, the higher the relative humidity of the space.
fresh air:
Fresh air distribution system should be used to remove particles, carbon dioxide, odors, dampness, moisture, etc.
Fresh air will also kill bacteria and viruses if proper filters are used.
The amount of fresh air will be obtained according to the functional type of the building and the spaces, the reference of which is the Ashrae62.1 standard.
Air distribution system:
In order to properly distribute the air and prevent air velocity, which will cause dissatisfaction in indoor spaces, the air velocity should be less than 64.1. As a result, the above issue should be considered in air distribution channels and valves.
