2. Cooling load temperature difference calculation method

   en.wikipedia.org/wiki/Cooling_load_temperature...

   The first of the cooling load factors used in this method is the CLTD, or the Cooling Load Temperature Difference. This factor is used to represent the temperature difference between indoor and outdoor air with the inclusion of the heating effects of solar radiation. [1] [5] The second factor is the CLF, or the cooling load factor.

3. Reflow oven - Wikipedia

   en.wikipedia.org/wiki/Reflow_oven

   This indirect heating using air allows more accurate temperature control than directly heating PCBs by infrared radiation, as PCBs and components vary in infrared absorptance. Ovens may use a combination of infrared radiative heating and convection heating, and would then be known as 'infrared convection' ovens.

4. Coefficient of performance - Wikipedia

   en.wikipedia.org/wiki/Coefficient_of_performance

   The coefficient of performance or COP (sometimes CP or CoP) of a heat pump, refrigerator or air conditioning system is a ratio of useful heating or cooling provided to work (energy) required. [1] [2] Higher COPs equate to higher efficiency, lower energy (power) consumption and thus lower operating costs. The COP is used in thermodynamics.

5. Thermal conductance and resistance - Wikipedia

   en.wikipedia.org/wiki/Thermal_conductance_and...

   Heating, ventilation, and air conditioning (HVAC): Understanding thermal resistance aids in optimizing heating, ventilation, and air conditioning systems for better energy efficiency. Thermal packaging: Ensuring proper thermal conductance and resistance is crucial for protecting sensitive goods during transport.

6. Newton's law of cooling - Wikipedia

   en.wikipedia.org/wiki/Newton's_law_of_cooling

   In particular, these investigators took account of thermal radiation at high temperatures (as for the molten metals Newton used), and they accounted for buoyancy effects on the air flow. By comparison to Newton's original data, they concluded that his measurements (from 1692 to 1693) had been "quite accurate". [4]

7. Fay-Riddell equation - Wikipedia

   en.wikipedia.org/wiki/Fay-Riddell_equation

   The equation was developed by James Fay and Francis Riddell in the late 1950s. Their work addressed the critical need for accurate predictions of aerodynamic heating to protect spacecraft during re-entry, and is considered to be a pioneering work in the analysis of chemically reacting viscous flow.
