Detailed description of the invention
Below in conjunction with accompanying drawing, the technical solution of the utility model is further described.
Fig. 1 is the structural representation of double-purpose heat exchange multi-connected air conditioner of the present utility model.As shown in Figure 1, double-purpose heat exchange multi-connected air conditioner of the present utility model, comprises compressor 1, cross valve 2, indoor air cooling heat exchanger 13 and outdoor heat exchange system.Outdoor heat exchange system forms closed cycle loop by refrigerant tubing 12 and compressor 1, cross valve 2, indoor air cooling heat exchanger 13, refrigerant tubing 12 is provided with electric expansion valve 11.Indoor air cooling heat exchanger 13 can arrange multiple, uses for different rooms.
Outdoor heat exchange system comprises double-purpose heat exchanger and soil heat exchanger 9, and soil heat exchanger 9 is connected with double-purpose heat exchanger by anti-freeze water solution pipeline 8.Double-purpose heat exchanger comprises heat exchanger fan 6, fin 3, coolant channel 4, anti-freeze water solution passage 5 and water pump 7.Anti-freeze water solution passage 5 is positioned at coolant channel 4, water pump 7 is arranged on following anti-freeze water solution pipeline 8, fin 3 is welded on outside the tube wall of coolant channel 4, heat exchanger fan 6 is positioned at the top of coolant channel 4, and outdoor air flows through tube wall and fin outside coolant channel by the draft of heat exchanger fan 6.
Soil heat exchanger 9 is connected with anti-freeze water solution passage 5, soil heat exchanger 9 is embedded vertically in soil, be connected with anti-freeze water solution passage 5 by anti-freeze water solution pipeline 8, anti-freeze water solution pipeline 8 be provided with water pump 7, in anti-freeze water solution pipeline 8, fill anti-freeze water solution.
