<p>A building built-in air conditioning system comprising: an external heat exchanger (1), a reversing valve (2), a compressor (4), and microporous tubes (9, 10, 11). The microporous tubes are metal capillaries bound on a construction steel bar (12) and integrated with the concrete by casting. each microporous tube has a first end welded to a first guiding tube and a second end welded to a second guiding tube, the plurality of microporous tubes are thus connected to the guiding tubes in parallel, the guiding tube on first ends of the microporous tubes is connected to the right-side port of the reversing valve 3, the second guiding tube on the second ends of the microporous tubes is connected to the lower port of the external heat exchanger 1 through a throttle component 5, the upper port of the external heat exchanger 1 is connected to the left-side port of the reversing valve 3, the center common port of the reversing valve 3 is connected to the return-air intake of the compressor 4, an inlet of the reversing valve 3 is connected to an outlet of the compressor 4. The external heat exchanger may be at least one of the heat exchangers including an air-cooled heat exchanger, a water-cooled heat exchanger, a foundation heat exchanger, and a solar panel heat exchanger. The air conditioning system has the advantages of longer life span, lower noise, and lower level of maintenance. The carbon emission and electricity cost of an air conditioning system according the example embodiments are also low.</p> |
