In whole dehumidifying humidification, using the control system of intelligent fuzzy by signal acquisition, operation and control, The dehumidifying humidification amount of precise control earth source heat pump unit 1, makes the ambient humidity in each rack of some racks reach certain model It is constant in enclosing.
(3)By underground pipe to the utilization process of superficial-layer geothermal energy
Be by subsurface temperature and the temperature difference of surface temperature carry out it is cold and hot exchange, realization superficial-layer geothermal energy is recycled.
Summer, the cold ground level heat in underground, the heat that earth source heat pump unit 1 is produced in process of refrigerastion is through medium(Water)From ground The EXIT POINT of source source pump 1 and ground source outlet pipe 12 flow into some groups of underground pipe pipelines of closing, transfer heat to ground Under, through buried under ground pipe cool down after water again through with journey pipe 26, source return pipe 10, water pump 11 and water entry enter ground source heat Pump assembly 1.
Winter, underground heat ground is cold, and the cold that earth source heat pump unit 1 is produced in heating operations is through medium(Water)From ground The EXIT POINT of source source pump 1 and ground source outlet pipe 12 flow into some groups of underground pipe pipelines of closing, are transferred to ground by cold Under, through underground underground pipe exchange heat after water again through with journey pipe 26, source return pipe 10, water pump 11 and water entry enter ground source heat Pump assembly 1.
Therefore say, the present invention comes for the energy of the constant temperature and humidity geothermal heat pump air-conditioning system cooling heat exchange of indoor and outdoor rack Natural energy resources are come from, it does not discharge any waste gas, waste water outwardly, waste residue, nor affects on underground water, be a kind of preferably " green Color air-conditioning ";It is cold and heat supply system most friendly to environment and maximally effective usable at present;All may be used in relatively broad area To apply.
