What the 'Dew Point' means in building thermography

Dew Point Measurement and Calculation

Dew point can be precisely measured using a range of instruments. Hygrometers, dew point meters, and psychrometers are commonly employed to accurately determine the levels of atmospheric moisture. Hygrometers directly measure humidity levels by detecting changes in the electrical or mechanical properties of a substance. Dew point meters specialise in measuring the exact temperature at which condensation occurs by monitoring the cooling of a surface until water vapor starts to condense. Psychrometers, on the other hand, use a combination of dry and wet bulb thermometers to calculate the dew point based on the difference in temperature readings. These devices play a vital role in weather forecasting, agriculture, and industrial processes by providing reliable and precise measurements of atmospheric moisture levels.

Dew Point Calculation Formulas

Dew point can be determined using mathematical formulas that rely on temperature and relative humidity. Scientists and meteorologists often employ two commonly used formulas: the Magnus-Tetens formula and the Arden Buck equation. The Magnus-Tetens formula, developed by Gustav Magnus and Max Tetens, provides an approximation of the dew point temperature by utilising the ambient air temperature and the relative humidity. On the other hand, the Arden Buck equation, named after Arden L. Buck, calculates the dew point temperature using the natural logarithm of the relative humidity and the air temperature. These formulas serve as valuable tools in meteorology, aiding in the understanding of atmospheric moisture and its impact on weather conditions.

Mitigating Fire Hazards and the Importance of Solar Panel Maintenance

Mitigating Fire Hazards – Solar Panel Maintenance Solar panels have gained significant popularity as a renewable energy solution in recent years. With their ability to harness the sun’s energy and convert it into electricity, solar panels contribute to a greener and more sustainable future. However, it is crucial to understand that like any other technology, solar panels require proper maintenance to ensure optimal performance and, most importantly, to minimize the risk of fire hazards. In this blog post, we will explore the reasons why solar panels can catch fire if not adequately maintained. We will delve into the various factors that can contribute to fire incidents, emphasizing the significance of proactive maintenance and regular inspections to mitigate these risks effectively. Electrical Overload and Faulty Wiring One of the primary causes of solar panel fires is electrical overload resulting from faulty wiring. Over time, exposure to environmental factors such as heat, moisture,...

Thermal Bridging in Commercial Buildings

Unveiling the Hidden Costs: Thermal Bridging in Commercial Buildings In the intricate world of commercial building design and construction, one often-overlooked factor plays a crucial role in energy efficiency – thermal bridging. This phenomenon, where heat easily transfers through the fabric of a building, not only impacts the comfort of its occupants but also significantly increases operational costs. The effects of thermal bridging on heat loss and its financial implications for commercial buildings, can be assessed by the itilisation of sophisticated technique of thermal imaging used to identify and mitigate this issue. Understanding Thermal Bridging: Thermal bridging occurs when a conductive material provides a pathway for heat to bypass the insulation, creating a direct route for heat to escape or enter a building. In commercial buildings, common thermal bridges include structural elements like steel or concrete connections, as well as poorly insulated junctions between walls a...

The Drone Based Solar Farm Heat Hunt 🔍

The world is moving towards renewable energy at a rapid pace, and solar farms are leading this transition. However, like any other technology, they come with their own set of challenges. One such challenge is identifying faults and anomalies such as ‘hotspots’ in the solar panels which can cause inefficiencies in energy production. Multiple hotspots, can lead to failing module panels and even whole strings. However, using drone technolegy aliong with thermal camera payloas, detecting these issues is simple and straightforward! In this article, we will explore how drone thermal inspections of solar farms is the new normal. Basking in the Sun: Drone-Powered Solar Farm Heat Hunts! Drones have revolutionised the way we approach solar panel maintenance. With the help of thermal imaging cameras, drones can easily detect hotspots and module and diode failures in solar panels. These faults can occur due to a variety of reasons, such as debris or shading as wells as mechnical failure or a ...
