  1. 1. Climate Control Product O P d t Overviewi Product Management, Rev 3 December 2009
  2. 2. Why climate control? Common Causes of Electrical/Electronic Equipment Failure  Name/Department of author Vibration 21% Humidity Heat 16% 57% Dust 6% Climate Control Overview Product Management, Rev 3 2
  3. 3. Why climate control? Reduction of the service life according to Arrhenius' law • Components generate heat ( (heat loss Qv) ) Integrated • Service life of components is circuits reduced when temperature is too high ars] • Examples include: Lifetime [yea Electrol.  Transformers condenser  Controls  Frequency converters L  Servers and network technology  Electrolytic capacitors Component temperature [°C] The challenge: A growing number of products needs climate control  Energy demand Climate Control Overview Product Management, Rev 3 3
  4. 4. Find the right climate control product: definition f k d fi iti of key parameters t Ta (°C/°F): Maximum ambient temperature Ti (°C/°F): (°C/°F) Required i t R i d internal t l temperature ( t (operating ti temp of most sensitive electronics) A (m2/ft2): Effective enclosure surface area per standard: VDE 0660 part 500 k (W/m2C): Enclosure overall heat transfer coefficient (“k-coefficient“) Qv (W): ( ) Heat loss from electronics Qs (W): Heat dissapated (Ti>Tu) or absorbed (Tu>Ti) through the enclosure surface Qe (W): Required cooling output Climate Control Overview Product Management, Rev 3 4
  5. 5. Find the right climate control product Required cooling capacity of climate control product Qe (W) = Qv – k • A • T T = (Ti - Ta) --------------------------------------------------------------------------- Example: enclosure with area of 52 ft2 = 4.82 m2 Given: Painted Carbon Steel Ta = 30°C (Maximum ambient temperature) Ti = 40°C (Maximum enclosure internal temperature) Heat load of components: 1000 W (Sum of All heat loss of components – drives, PLCs) Qe (W or BTU) = 1000 W - 5.5(W/m2C) * (4.82 m2) * (40°C - 30°C) = 735 W = 2500 BTU ( q (Required cooling capacity) g p y) Climate Control Overview Product Management, Rev 3 5
  6. 6. Find the right climate control product: Rittal Sizing Software Th Ritt l Si i S ft Therm 5.14 5 14 Program calculates: • Exact area of enclosure surfaces • Amount of heat dissipated to the environment • The resulting required cooling capacity 4 • The temperature inside the enclosure with climate control measures Program generates: • A proposal for all possible alternatives to solve your particular enclosure climate control requirements. • You can then decide which is the optimum solution for you application.
