Abstract：
 The invention discloses a solar-energy soil ultra-critical carbon dioxide heat pump air-conditioning system. The invention comprises an ultra-critical carbon dioxide heat pump medium circulator, a solar-energy collector, an underground tube heat exchanger, and an indoor air-conditioning tube. The invention arranges heat exchange coil tube, evaporator/gas cooler in the heat accumulating box, via four-way valve and valves to connect them into one air-conditioning system. The invention can work in five modes as heating, refrigerating, heating water, heating-heating water, and refrigerating-heating water, to heat water, refrigerate and supply heat.
