The buildings are insulated, and temperature control is assured either by ventilation with outside air (i.e., for potatoes and onions) or by refrigeration (i.e., for apples).
Wireless radios will be positioned on moving glaciers, and gear must be insulated against temperatures far colder than they were designed to withstand.
In an adequately insulated home, the temperature is constant throughout each room and walls, ceilings and flooring remain warm in the winter and cooler in the summer months.
Walls of the enclosure are insulated and constant temperature conditions are given for hot (Th) and cold (Tc) pipes (Th > Tc).
It is assumed that interface crack is partly insulated, and the temperature drop across the crack surfaces is the result of the thermal resistance due to the heat conduction through the crack region.
The result is serious mountaineering hardware: a sturdy yet surprisingly lightweight boot with a breathable Kevlar upper and Duratherm lining that insulates against temperatures down to minus 25 degrees Celsius.
The white-colored polyurethane foam plug located between the PoE unit and the magnetic sensors thermally insulates the temperature-sensitive magnetic sensors from heat emanating from the electronics and the upper portion of the enclosure pipe that is exposed above ground.
A new ebulliometer has been developed in which superheat is discharged from the vapour liquid mixture issuing from the Cottrell pump before it impinges on an otherwise vacuum-insulated temperature sensor.
Small amounts of hair (up to one cm) have very little effect on the overall temperature of the skin after twelve minutes in cold temperatures, but once hair reaches a thickness of two cm, the head becomes significantly insulated and skin temperatures are much higher.
Thus, the flow rates in the tubing and annulus 1 are equal (dot{m}_{t } = dot{m}_{{{text{a}}1}}.) Insulated tubing temperature T t is defined as temperature at the condenser exit T cond.out and additional temperature gain at the pump stage (Delta T_{{{text{wf}}.{text{p}}}}): T_{text{t}} = T_{{{text{cond}}.{text{out}}}} + Delta T_{{{text{wf}}.{text{p}}}} (43).
