Wet Bulb Dry Bulb Tool
Relative humidity and temperature play a large role in creature comfort and commissioning of hvac systems.
Wet bulb dry bulb tool. Meanwhile they both will be the dry and wet bulb thermometers that you could use to measure the relative humidity in a certain area. The wetbulb globe temperature wbgt is a measure of the heat stress in direct sunlight which takes into account. The wet bulb temperature is the adiabatic saturation temperature. It can handle temperature from 40 to 300 f which is outstanding.
This is a great tool. Lower dry bulb temp without changing the dew point temp wet bulb goes down. The adiabatic evaporation of water from the thermometer bulb and the cooling effect is indicated by a wet bulb temperature lower than the dry bulb temperature in the air. The dry bulb temperature is also known simply as air temperature.
It has a wide temperature range and an excellent warranty. Temperature humidity wind speed sun angle and cloud cover solar radiation. And the warranty is 5 years for the tool and 1 year for the probe. Wet bulb dry bulb and relative humidity.
It gives hvacr professionals more insight into hvac evaporator performance than any other psychrometer because it takes four evaporator measurements at one time. The wet bulb temperature might not be a widely known measure but it has some valuable functions. Wet bulb temperature can be measured by using a thermometer with the bulb wrapped in wet muslin. Raise dry bulb temp without changing the dew point temp wet bulb temp goes up.
The natural wet bulb temperature is best described as an old fashioned thermometer wrapped in a wet cloth. The sdp2 dual in duct psychrometer is more than just your everyday hvacr psychrometer. Wet bulb temperatures are always lower than dry bulb temperatures with less than 100 relative humidity in the air. Fieldpiece meters like the arh5 and the arh4 are staple instruments for every technician tool box.
The uncovered thermometer measures dry bulb temperature while the one covered with wet cloth measures wet bulb temeprature. As water evaporates from that wet cloth evaporation cools the thermometer which is identical to how the human body cools itself with sweat. Imo wet bulb in hvac work is more useful when dealing with evaporative cooling concerns such as with cooling towers and swamp coolers. The wet bulb temperature and the dry bulb temperature will be identical with 100 relative humidity in the air the air is at the saturation line.
Since both the thermometers are placed side by side the mositure from wet wick may affect the readings of dry bulb thermometer to avoid this the wet bulb thermometer is placed at the lower level. Supply wet bulb supply dry bulb return wet bulb and return dry bulb.
