Direct refrigerant geothermal heat exchange or multiple source subcool/postheat/precool system therefor

First, a system for providing liquid refrigerant subcooling, subsequent to that subcooling accomplished by the primary condenser, by means of direct geothermal heat exchange and if required, secondary (or more) fluid(s) supplementary cooling of the liquid refrigerant contiguous with the direct geothermal subcooling. This system could be utilized with standard condensers for higher efficiency air conditioning, heat pump in the cooling mode, or refrigeration operation of any kind. No modifications to the actual condenser would be required, but a larger evaporator surface could be required.Secondly, a system for providing supplemental heat to the primary evaporator of a heat pump operating in the heating mode, by means of a direct geothermal heat exchange, coupled with heat reclaim of the liquid refrigerant, and if necessary with secondary (or more) fluid(s). This system would require some modification of a standard heat pump in addition to the installation of the direct geothermal liquid refrigerant reclaim, secondary (or more) fluid heat postheater. Next, a system that would provide liquid refrigerant subcooling by means of direct geothermal heat exchange and if required, secondary (or more) fluid(s) supplementary subcooling, coupled with a system that would provide direct geothermal, plus a possible secondary (or more) fluid, supplementary heat, to a postheater of a heat pump in the heating mode. That said postheater becoming a precooler of the hot gas refrigerant when the heat pump is in the cooling mode. Finally, a system that would provide liquid refrigerant subcooling by means of direct geothermal heat exchange and if required, a secondary (or more) fluid(s) supplementary subcooling coupled with a system that would provide direct geothermal heat exchange precooling of the hot gas refrigerant and if required, a secondary (or more) fluid(s) precooling of the hot gas refrigerant. This system could be utilized with standard air source or water source air conditioning or refrigeration condensers for producing more capacity and higher efficiency.

Visual analysis method based on online social media personal center network

The invention discloses a visual analysis method based on an online social media personal center network, belongs to the technical field of electronic information, and solves the problem that the effectiveness of recommendation cannot be ensured in the prior art. The method includes: on the basis of the online friend relationship data and offline sign-in data of each central user, calculating thecommunity characteristics and the distribution of repeated sign-in POI types; constructing social feature parameters of the consistency of the online relation and the offline activity, and selecting features capable of reflecting social behavior characteristics of all aspects from the social feature parameters to form social feature vectors; dividing friend types different social circle friend types by adopting an unsupervised clustering algorithm based on the social feature vectors, namely a POI type social network; performing visual design coding based on the community characteristics and the distribution of the repeated sign-in POI type to obtain a corresponding visual view; based on the POI type social network and the visual view, achieveing visual analysis of the social network from the overall social network to the POI type social network to the central user level. The method is used for visual analysis of the personal center network.
