Correlation Between Insulation Resistance and Temperature Measurement Error in Type K and Type N Mineral Insulated, Metal Sheathed Thermocouples
<p>Mineral insulated, metal sheathed (MI) Type K and Type N thermocouples are<br> widely used in industry for process monitoring and control. One factor that limits<br> their accuracy is the dramatic decrease in the insulation resistance at temperatures<br> above about 600 °C which results in temperature measurement errors due to electrical<br> shunting. In this work the insulation resistance of a cohort of representative MI<br> thermocouples was characterised at temperatures up to 1160 °C, with simultaneous<br> measurements of the error in indicated temperature by in situ comparison with a reference<br> Type R thermocouple. Intriguingly, there appears to be a systematic relationship<br> between the insulation resistance and the error in the indicated temperature. At<br> a given temperature, as the insulation resistance decreases, there is a corresponding<br> increasingly negative error in the temperature measurement. Although the measurements<br> have a relatively large uncertainty (up to about 1 °C in temperature error and<br> up to about 10 % in insulation resistance measurement), the trend is apparent at all<br> temperatures above 600 °C, which suggests that it is real. Furthermore, the correlation<br> disappears at temperatures below about 600 °C, which is consistent with the<br> well-established diminution of insulation resistance breakdown effects below that<br> temperature. This raises the intriguing possibility of using the as-new MI thermocouple<br> calibration as an indicator of insulation resistance breakdown: large deviations<br> of the electromotive force (emf) in the negative direction could indicate a correspondingly<br> low insulation resistance.</p>

A FIELD STUDY ON THERMAL INSULATION PERFORMANCE OF GREEN ROOF FOR BUILDINGS IN HOT DRY CLIMATE OF ZARIA, NIGERIA
<p>Although the practice of employing the use of green roof for thermal insulation is gaining a wideranging acceptance across the globe, its use in Nigeria and the sub Saharan Africa has remained unpopular. Study has shown that, although a vast literature on different approaches in the application of green roof system exists, there is substantial misrepresentation of inferences regarding its applications in Nigeria. The purpose of the study therefore, is to assess the thermal performance of green roof in facilitating thermal insulation for building interiors of hot dry climate in Nigeria. The study is carried out through an empirical field observation in the premises of Ahmadu Bello University Zaria, Nigeria. Two miniature live models were built and covered with galvanised iron roofing sheets on timber trusses; one of which was covered with green roof, while the other was left bare. This is with the view to determine the rate of thermal insulation a green roof system can offer over the bare roof in the building interiors of the study area. Using the experimental approach in green roof investigation, a data logging system was installed in the two thermal zones and readings of the temperature profile was taken. The results showed that; a reduction of 2.08°C in indoor air temperature was obtained on the diurnal ranges, while 19.78% of temperature fluctuation was achieved. Generally, the result showed that higher temperature ranges were recorded in the bare roofed case than the green roof. The maximum, mean and minimum record for the bare roof was 45.20°C, 32.03°C and 21.10°C respectively; while the recorded values for the green roof were 41.90°C, 29.95°C, and 21.00°C respectively. This implies that, the presence of vegetation on the green roofed case has offered a degree of thermal insulation required to achieve better passive cooling in order to attain thermal comfort in the interiors of the study area.</p>

How to transport veterinary drugs in insulated boxes to avoid thermal damage by heating or freezing
<p><strong>Documentation of the empiric data, measured in the heating and cooling chamber to determine the thermal constant for the investigated transport boxes.</strong></p> <p> </p> <p><strong>Background: </strong>The transport of veterinary drugs must comply with the general standards for drug storage. Although many vehicles are equipped with active heating and/or cooling devices assuring recommended storage conditions, simple insulated transport boxes are also often used. In this study, measurements for typical transport boxes were performed under laboratory conditions by the use of a climate chamber for a temperature of -20°C and 45°C to investigate the impact of box size, insulation material, liquid vs. dry filling products, filling degree and other parameters on the thermal performance of insulated boxes. Model calculations and instructions are presented to predict the retention time of recommended drug storage temperatures.</p> <p><strong>Results: </strong>The measurements and the model calculations showed that the loading of the transport boxes with additional water bottles to increase the heat capacity is appropriate to prolong the retention time of the recommended temperature range of the drugs. Insulated transport boxes are not suitable to store drugs over a period of more than approximately 12 hours. For practical use, a recipe is presented to measure the thermal properties of a transport box and the related retention time for which the recommended storage temperatures can be assured.</p> <p><strong>Conclusions: </strong>The following principles for drug transportation in vehicles are recommended: (1) Before transfer into boxes, drugs should always be thermally preconditioned (2) Increase the filling degree of the boxes with thermally preconditioned water bottles or re-usable thermal packs will increase the heat capacity. Do not deep-freeze the bottles or packs below 0°C to avoid drug freezing due to contact. (3) Open the lid of the boxes only to uncase drugs that are immediately needed. (4) The bigger the box and the higher the filling degree, the longer the retention time of the transport box. (5) Wherever possible, place the drug box at a cool site inside the vehicle. (6) The monitoring of the inside temperature of the transport boxes is recommended. <br> By the proper use of such transport boxes the recommended temperatures can be maintained over one working day.</p> <p> </p>

Thermal adaptation of pelage in desert rodents balances cooling and insulation
<p>Phenotypic convergence across distantly related taxa can be driven by similar selective pressures from the environment or intrinsic constraints. The roles of these processes on physiological strategies, such as homeothermy, are poorly understood. We studied the evolution of thermal properties of mammalian pelage in a diverse community of rodents inhabiting the Mojave Desert, U.S.A. We used a heat flux device to measure the thermal insulation of museum specimens and determined whether thermal properties were associated with habitat preferences while assessing phylogenetic dependence. Species that prefer arid habitats exhibited significantly lower conductivity and thinner pelage relative to species with other habitat preferences. Despite having thinner pelage, the low conductivity imparted comparable insulation to species with other habitat preferences. Thus, arid species retain insulative pelage while simultaneously benefitting from thin pelage that promotes heat loss via convective cooling. We found no evidence of intrinsic constraints or phylogenetic dependence. Heat flux models designed to simulate body temperature regulation demonstrated that arid specialists saved 14.5% of their annual energy required for homeothermy by evolving lower conductivity, providing support for adaptive evolution of pelage. Our study indicates that selection for lower energetic requirements of homeothermy has shaped evolution of pelage thermal properties.</p>
