Higher efficiency of the cooling unit

Abstract

The paper describes the issue of the combined work of the cooling unit with the air direct-contact, gravel, ground heat exchanger (Polish acronym BGWCiM), patented for the Wroclaw University of Science and Technology. The options of the combined work have been discussed; the document also presents schemes and proposes the algorithms of work. The cost-efficiency of the energy harvesting from the ground by the means of the proposed solution have been analyzed and compared for two work modes, with and without the BGWCiM. Moreover, the research results and experimental measurements were presented and discussed.
