A psychrometer is an instrument used to measure the relative humidity of air. It consists of two thermometers, one with a dry bulb and one with a wet bulb.

True, However, cooling load calculations take into account various factors such as outdoor temperature, solar radiation, building orientation, insulation levels, internal heat gains, ventilation rates, and thermal properties of the building envelope.

This is based on the average amount of heat that a person generates in a typical home. The actual allowance may vary depending on the size and activity level of the person.

As you go higher, there is less air above you, so the atmospheric pressure decreases.

For a home with 3 people, the ventilation system should provide at least 20 cfm of fresh air per person, or 60 cfm total.

Air / Water cooled chillers use a compressor to cool water, which is then circulated through a heat exchanger to remove heat. Absorption chillers use a chemical reaction to absorb heat from the air. Evaporative cooling towers use the evaporation of water to cool the air.

Evaporative cooling systems are a type of cooling technology that utilizes the natural process of evaporation ( when water evaporates, it absorbs heat from the surrounding air) to cool the air thereby reducing dry bulb temperature. These systems are commonly used in dry and arid climates to provide effective and energy-efficient cooling for buildings.

Absolute humidity is the actual mass of water vapor in one cubic foot of air. It depends on the temperature and pressure of the air. As the temperature of air increases it can hold more water vapor. As the pressure of air increases it can also hold more water vapor.

A study by the U.S. Department of Energy found that increasing ACH from 0.5 to 2.0 can reduce energy costs for heating and cooling by up to 20%.

No, humidification is the process of adding moisture to the air. It is done to: Improve comfort in dry environments,  reduce the risk of static electricity, prevent the growth of mold and mildew, and help people with respiratory problems.

As per Boyle’s law, the absolute pressure of a gas at constant temperature varies inversely to its volume.

A dry-bulb thermometer is a thermometer that measures the temperature of the air without taking into account the moisture content of the air. It measures the temperature of the air by an ordinary thermometer.

Ventilation requirement depends on the number of occupants, type of activity, size of the space, climate, type of building construction, and presence of hazardous materials
