Ground heat exchangers—A review of systems, models and applications
TL;DR: In the literature, several calculation models are found for ground heat exchangers as discussed by the authors, which can accommodate for any type of grid geometry that may give greater detail of the temperature variation around the pipes and in the ground.
Thermohydraulic design of earth-air heat exchangers
Arnold Janssens,Michel De Paepe +1 more
TL;DR: In this paper, a one-dimensional analytical method is used to analyse the influence of the design parameters of the heat exchanger on the thermo-hydraulic performance and a relation is derived for the specific pressure drop, linking thermal effectiveness with pressure drop of the air inside the tube.

Heat and water vapour transfer in a greenhouse with an underground heat storage system part I. Experimental results
TL;DR: A greenhouse with an underground heat storage system consisting of two layers of 0.125m diameter PVC drain pipes buried 0.8 and 0.5 m deep, and a centrifugal fan circulating the greenhouse air, was tested with a classical crop rotation lettuce-tomato as mentioned in this paper.

The performance of a greenhouse heated by an earth-air heat exchanger
G.N. Mavroyanopoulos,S. Kyritsis +1 more
TL;DR: The greenhouse air temperature was adjusted by blowing the greenhouse air through the pipe system whenever the air temperature dropped below 12°C or exceeded 28°C as discussed by the authors, which resulted in a minimum mean night air temperature of 8.1°C inside the greenhouse with an absolute minimum of 7°C while the outside minimum mean and absolute minimum air temperatures were −0.8°C and −3.0°C, respectively, during the same period.
