Molecules in the air move faster as the temperature increases, and they can hold more water vapor

Sensible cooling is the process of removing heat from air without changing its moisture content.

The larger the temperature difference between the evaporator and the air, the more heat is absorbed by the refrigerant. This means that more moisture can be removed from the air.

Higher compression ratio will result in a higher discharge temperature, which requires a larger condenser to dissipate the heat (load on the condenser increases).

The heat rejection factor is an important factor in the design and operation of refrigeration plants. The heat rejection factor depends on the evaporator temperature (the lower the evaporator temperature, the more heat is rejected by the plant), condenser temperature (the higher the condenser temperature, the less heat is rejected by the plant), compressor efficiency (A more efficient compressor will reject more heat), compressor fan speed, compressor surface area, and refrigerant type

Forced draft fans are commonly used in the bottom or lower section of a cooling tower. These fans are responsible for drawing or forcing ambient air into the cooling tower, facilitating the cooling process.

The density of water vapor is extremely lower than that of liquid water. When water undergoes a phase change from liquid to gas (vapor) through evaporation, its density decreases. The decrease in density occurs because the water molecules in the vapor phase are more spread out compared to when they are in the liquid phase.

Oxygen levels below 19.5% can be dangerous for human health. The normal atmospheric air we breathe typically contains about 20.9% oxygen. When the oxygen concentration in the air drops below 19.5%, it can lead to oxygen deprivation or hypoxia, which can have various adverse effects on the body.

When the sensible load comes down, the air conditioning system is no longer able to remove as much moisture from the air. Reheat coils help to increase the temperature of the air, which helps to reduce the amount of moisture that can be held in the air.

Evaporative cooling is a process that uses water to cool air. When water evaporates, it absorbs heat from the surrounding air.

Mercury vapor lamps emit ultraviolet light in the UV-C range, which is effective at killing bacteria and viruses.

To measure static pressure, a manometer typically consists of a U-shaped tube partially filled with a liquid, such as water or mercury.

This is because heated air is less dense than cold air, so it rises. temperature stratification can lead to insufficient  air conditioning, discomfort, and poor air quality
