My masters' Thesis concerns a supermarket chain's cold systems' efficiency.
As a part of my work I need to have a reasonable approximation of cold room's refrigeration load.
It is easy to have a good approximation of heat transfer through walls and roof with basic heat transfer knowledge, however I am a little bit "lost" when trying to figure out the heat transfer through the ground.
What is usually the thermal load per sq meter of uninsulated floor in a cold room? The mean coldroom I'm studying has an area of 15-20 sq m, inside temperature of around 1-5 C (medium temperature) or -20 C (low temperature) and the mean ground temperature for this geographic region is around 15 C
Thank you!
