[0036] The present invention integrates the magnetic suspension free free centrifugal compressor and the deep layer to improve the heating performance of the heat pump, and COP has increased from the original effect, reducing cost, reduces the industrialized buddu area of traditional buried tube, saving land use. Compared to the conventional oil lubricating bearing device, the oil-proof compressor in the patent of the present invention is better, and the heat transfer effect of the heat pump unit evaporator and condenser is better.
[0037] In the traditional oil return device, the system can cause oil, thereby reducing the performance of the device, but also ensures oil in the compressor, and the traditional heat pump equipment has about 95% of the fault from the oil system, which can be used. Make the device down to 1% due to the fuel supply. The traditional oil lubrication system is at the cost of reducing the cooling heat transfer effect, and the concentration of about 2% of the evaporator oil reduces the reduction in the amount of refrigeration of about 6%, and the maglev is used in the patented maglevs, which can avoid oil. The presence of the refrigerant mixture in the system, avoiding the attenuation of the refrigeration amount of the oil system, and also greatly enhances the performance of the heat pump system by the application of the medium deep layer.
