Abstract

Gruntowy powietrzny wymiennik ciepła zawierający czerpnie powietrza, filtr, rurociąg wlotowy, skrzynki powietrzne, studnie kontrolne oraz ruro-ciąg zewnętrzny transportujący powietrze z czerpni do układu wentylacji budynku, a także rurociąg wewnętrzny, znajdującym się wewnątrz ruro-ciągu zewnętrznego, przeciwprądowo transportujący powietrze z układu wentylacji budynku, usuwane rurociągiem wyrzutowym przez wyrzutnię, charakteryzuje się tym, że rurociąg zewnętrzny (2) umieszczony jest co najmniej 1 metr pod poziomem terenu. Natomiast rurociąg wewnętrzny (1) wykonany jest z materiału o takim samym lub wyższym współczynniku przewodzenia ciepła jak rurociąg zewnętrzny (2). A ponadto pole powierzchni rurociągu zewnętrznego (2) pomniejszone o pole powierzchni przekroju rurociągu wewnętrznego (1) jest większe lub równe polu powierzchni przekroju rurociągu wewnętrznego (1), Dodatkowo rurociąg zewnętrzny (2) umieszczony w gruncie jest obsypany i zasypany mieszaniną (4) w postaci piasku pylastego o dużym współczynniku przewodzenia ciepła lub mieszaniną piaskowo-bentonitową, o miąższości co najmniej 20 cm, przy czym na załamaniach kierunków rurociągu zewnętrznego znajdują się studnie kontrolne (9), w których umieszczone są skrzynki powietrzne (7) zawierające kolano zmiany kierunki rurociągu wewnętrznego (1) oraz kierujące strugi powietrza dla rurociągu zewnętrznego (2). Rurociąg zewnętrzny (2) wraz z rurociągiem wewnętrznym (1), przed wprowadzeniem do układu wentylacji budynku, podłączone są do systemu wentylatorów lub centrali nawiewno-wywiewnej.A ground air heat exchanger containing air intakes, a filter, an inlet pipeline, air boxes, control wells and an external pipeline transporting air from the air intakes to the building ventilation system, as well as an internal pipeline located inside the external pipeline, countercurrently transporting air from the system ventilation of the building, removed through an ejection pipeline through the launcher, is characterized by the fact that the external pipeline (2) is located at least 1 meter below ground level. The internal pipeline (1) is made of a material with the same or higher thermal conductivity as the external pipeline (2). In addition, the surface area of the external pipeline (2) reduced by the cross-sectional area of the internal pipeline (1) is greater than or equal to the cross-sectional area of the internal pipeline (1). In addition, the external pipeline (2) located in the ground is covered and filled with the mixture (4) in forms of dusty sand with a high heat conduction coefficient or a sand-bentonite mixture, at least 20 cm thick, with control wells (9) on the bends of the external pipeline, in which air boxes (7) containing the knee change pipeline directions are placed internal (1) and directing air streams for the external pipeline (2). The external pipeline (2) together with the internal pipeline (1), before entering the building ventilation system, are connected to the fan system or the supply and exhaust air handling unit.
