The temperatures of each portion of the system 100 are selected to be relatively high (compared to conventional refrigeration-based cooling systems), so as to permit more efficient operation of the system 100. For example, relatively high air temperatures in the system (e.g., air entering a cooling coil over 110°F (43.3°C(*度、摂氏;丸+C)

The temperature rise can be large. For example, the work space 106 temperature may be about 77° F. (25° C.(*度、摂氏;丸+スペース(本来不要のはず)+C+
ピリオド)) and the exhaust temperature into the warm-air plenums 104 a, 104 b may be set to 113° F. (45° C.), for a 36° F. (20° C.)) rise in temperature. The exhaust temperature may also be as much as 212° F. (100° C.) where the heat generating equipment can operate at such elevated temperature.

Monitoring module 210 may wait to transmit the results until a temperature differential meets some threshold, such as 0.25° F. or 0.2° C.(*度、摂氏), or simply transmit after some duration of time or number of tests have been performed.
As noted, a temperature reading need not be accurate though it does have to be consistent to within the range at which an infection is detected, such as 0.1, 0.3, 0.5, or 1.0 degrees (Fahrenheit or Celsius).
EP2928671
For example, some parts may need to survive usage in some airframe locations that have in-service temperature ranges from around -54 degrees Celsius(*度、摂氏)to around 225 degrees Celsius.

In some embodiments, the heaters 108 are quartz rod elements, which are stable at temperatures in excess of 400° Celsius(*度、摂氏). In an exemplary embodiment, the heaters 108 may produce and maintain a consistent and stable temperature between 20° Celsius and 400° Celsius.
It will be appreciated that for many applications, a uniform, approximately constant temperature across the powder in the part bed is desired. For example, the CPU 120 may determine that zone 2 is 4° C. warmer than a target temperature (e.g., 163° C.(*度、摂氏)) in the zone heat distribution 118.
EP3391436
Above a critical temperature, exothermic reactions can occur that cause further temperature increase, which may result in additional exothermic reactions leading to thermal runaway. A thermal runaway can be a significant safety issue. For example, with a Li-ion battery, temperatures as high as 900 °C(*度、摂氏)may occur as well as the release of a substantial amount of flammable and toxic gas.
In embodiments, the wax/phase change material 30 is configured to melt at a suitable temperature (e.g., 80 degrees Celsius).

In the one embodiment, such chilled water temperatures are controlled to approximately 5.6 degrees Celsius (° C.) (42 degrees Fahrenheit (° F.)).
