Rise in room temperature over a one hour period

Click For Summary
SUMMARY

The discussion centers on calculating the temperature rise in a room with no cooling, measuring 5m x 4m x 2.5m, and experiencing a heat dissipation of 65kW from equipment. The ambient temperature is 20 degrees Celsius. It is established that, under the assumption of perfect insulation and constant pressure, the temperature could rise approximately 3600°C in one hour, illustrating that the room will increase in temperature at a rate of about 1°C per second until heat loss equals heat gain.

PREREQUISITES
  • Understanding of thermodynamics principles, particularly heat transfer.
  • Familiarity with the concept of heat dissipation in enclosed spaces.
  • Basic knowledge of room dimensions and volume calculations.
  • Awareness of insulation properties and their impact on temperature regulation.
NEXT STEPS
  • Research heat transfer equations and their applications in thermal dynamics.
  • Explore methods for calculating heat loss through walls and ventilation systems.
  • Learn about insulation materials and their effectiveness in temperature control.
  • Investigate cooling solutions for equipment-heavy environments to manage heat dissipation.
USEFUL FOR

Engineers, HVAC professionals, and anyone involved in thermal management of spaces with high heat output from equipment.

I have a room with no cooling.

Room info : w = 5m l = 4m h= 2.5m
Heat dissipation from equipment in room= 65kw
Ambient temp = 20 degrees celsius

I need to know the temperature rise over a one hour period

Please help

Thanks

If the room is perfectly insulated and held at a constant pressure (not perfectly sealed), I get a back of the envelope answer that it will rise in temperature by about 3600C in an hour. Obviously, this isn't correct, but this demonstrates that the room will rapidly rise in temperature (~1 degree C per second) until the heatflow out through the walls and whatever venting system exists is equal to the heatflow in.
