It is based on place deep underground (at least 2m) in the form of heat exchanger tubes with large diameter (eg 200mm) or gravel deposits . The idea of ground heat exchanger work involves the use of energy of the earth to the air cooling for mechanical ventilation in summer (several – a few degrees), and heating it to the same value in the winter.
Ni kwa kuzingatia mahali kirefu chini ya ardhi (angalau 2m) katika fomu ya zilizopo exchanger joto na kipenyo kubwa (kwa mfano 200mm) au amana changarawe . wazo la â € <â € <joto ardhi exchanger kazi inahusisha matumizi ya nishati ya nchi kwa ajili ya uingizaji hewa baridi hewa mitambo katika majira ya joto (kadhaa – nyuzi kadhaa), na kukanza kwa thamani sawa katika majira ya baridi .
