(3) by underground pipe process is utilized to superficial-layer geothermal energy
Be carry out cold and hot exchange by the temperature difference of subsurface temperature and surface temperature, realize recycling superficial-layer geothermal energy.
Summer, the cold ground level heat in underground, the heat produced in process of refrigerastion by earth source heat pump unit 1 flows into from the EXIT POINT of earth source heat pump unit 1 and ground source outlet pipe 12 the some groups of underground pipe pipelines closed through medium (water), by transfer of heat to underground, through the cooled water of buried under ground pipe again through with journey pipe 26, source return pipe 10, water pump 11 and water entry enter earth source heat pump unit 1.
Winter, underground heat ground is cold, the cold produced in heating operations by earth source heat pump unit 1 flows into from the EXIT POINT of earth source heat pump unit 1 and ground source outlet pipe 12 the some groups of underground pipe pipelines closed through medium (water), cold is transferred to underground, the water after the underground pipe heat exchange of underground again through with journey pipe 26, source return pipe 10, water pump 11 and water entry enter earth source heat pump unit 1.
Therefore say, the present invention is used for the energy source of the constant temperature and humidity geothermal heat pump air-conditioning system cooling heat exchange of indoor and outdoor rack in natural energy resources, and it does not outwardly discharge any waste gas, waste water, waste residue, does not affect underground water yet, is a kind of desirable " green air conditioner "; Be at present spendable to environment the most friendly and the most effective cold and heat supply system; Can apply in area comparatively widely.
