RH control refers to the regulation of relative humidity levels in a given space.
RH control is important for maintaining indoor air quality and preventing mold growth.
It can be achieved through the use of HVAC systems, dehumidifiers, and ventilation.
RH levels should ideally be kept between 30-50% to ensure comfort and health.
Factors such as temperature, air flow, and moisture sources can affect RH levels.
Monitoring RH ...
Preventive maintenance takes time to ensure equipment is functioning properly and prevent breakdowns.
Preventive maintenance involves inspecting and cleaning equipment to ensure it is functioning properly.
It also involves replacing worn or damaged parts before they cause a breakdown.
Regular maintenance can help prevent costly repairs and downtime.
Examples of preventive maintenance tasks include changing air filters, lub...
Performance verification takes time to ensure that the HVAC system is functioning properly and efficiently.
Performance verification involves testing and measuring various components of the HVAC system.
This process can take several hours or even days depending on the size and complexity of the system.
The goal is to ensure that the system is operating at peak performance and efficiency, which can save energy and reduce c...
Temperature control is achieved through the use of HVAC systems that regulate the flow of air and heat.
HVAC systems use sensors to detect the temperature in a room or building
The system then adjusts the flow of air and heat to maintain a desired temperature
This is achieved through the use of thermostats, dampers, and fans
For example, if the temperature is too high, the system will increase the flow of cool air and decr...

Distillation is a process of separating components of a mixture based on their boiling points.
It involves heating the mixture to vaporize the component with the lowest boiling point.
The vapor is then condensed and collected as a separate liquid.
Types of distillation include simple distillation, fractional distillation, and steam distillation.
Simple distillation is used for separating liquids with large differences in b...
A catalyst is a substance that increases the rate of a chemical reaction without being consumed in the process.
Catalysts lower the activation energy required for a reaction to occur.
They provide an alternative reaction pathway with a lower energy barrier.
Catalysts can be in the form of enzymes, metals, or other substances.
They are not consumed or permanently changed during the reaction.
Examples include platinum in cata...
pH is a measure of the acidity or alkalinity of a solution. It ranges from 0 to 14, with 7 being neutral.
pH stands for 'potential of hydrogen'
It measures the concentration of hydrogen ions in a solution
A pH value below 7 indicates acidity, while above 7 indicates alkalinity
Pure water has a pH of 7, which is considered neutral
Examples of pH values: lemon juice (pH 2), baking soda (pH 9), stomach acid (pH 1)
PH is a measure of acidity or basicity of a solution. It ranges from 1 to 14, with 7 being neutral.
PH = - log into base H+ ion concentration
Range of PH: 1 to 6.9 acidic, 6.9 to 7.1 neutral, 7.1 to 14 basic
Acidic solutions have a higher concentration of H+ ions, while basic solutions have a higher concentration of OH- ions
PH is important in many fields, including chemistry, biology, and environmental science

Density is the measure of mass per unit volume of a substance.
Density is calculated by dividing the mass of a substance by its volume.
It is a physical property that can be used to identify substances.
The density of a substance can change with temperature and pressure.
Water has a density of 1 gram per cubic centimeter.
The density of air is much lower than the density of water.
