Thermal Convection and Radiation Values: Difference between revisions

Latest revision as of 00:32, 8 February 2026

This is a collection of thermal convection, radiation, and solar heating values for easy comparison to one another.

Pipe Network

Note that all equivalent liquid structures have the same values as their gas counterparts, except for the Liquid Pipe Convection Radiator which is listed separately.
Insulated tanks, pipes and in-line tanks have zero for all values.
Solar heating does not seem to apply to pipe-mounted radiators.

Pipe Network Structure	Thermal Convection	Thermal Radiation	Solar Heating
Pipe	0.005	0.001*	0.05
Pipe Radiator	0.231	3.46	2.31
Pipe Convection Radiator	1.05	0.79	0.105
Liquid Pipe Convection Radiator	1.02	0.763	0.102
Medium Radiator	1.5	30	15
Medium Convection Radiator	9.38	3	1.5
Large Extendable Radiator	0.736	73.6	950 (at 100% efficiency)*
Small Tank	0.758	0.03	1.52
Large Tank	4.24	0.17	8.49
In-Line Tank Gas	0.025	0.001	0.25
In-Line Tank Small Gas	0.015	0.001	0.152

* Not listed in stationpedia, approximated value

Heat Exchangers

Heat exchangers are different from most other atmospheric devices because they operate between pipe networks instead of an internal volume and outside atmosphere. Heat transfer between two networks follows the same rules as thermal convection.

Exchanger	Thermal Convection
Small Direct Heat Exchanger	1
Large Direct Heat Exchanger	8
Super Large Direct Heat Exchanger	28

Counterflow heat exchangers are not easily comparable to direct heat exchangers. See external link below.
