Original Abstract
Air-ground heat exchangers (AGHE) are used for preheating of ventilation air in winter, and for precooling in summer. Currently, AGHEs are often proposed as a complement to the warm-air heating system. In such case, winter preheating also serves as an anti-frost protection of a heat recovery unit. The paper deals with annual energy simulation of AGHE and its cooperation with warm-air heating system in a new-built low-energy family house in a North Moravia region. Simplified model created in TRNSYS code was used. Four variants were solved: exploitation of AGHE with and without heat recovery, and the same cases without AGHE as comparative variants. Consequent energy savings are compared with investment costs.
