The invention provides a regional cooling and heating transmission and distribution pipeline network health inspection system, which includes a water separator, a water collector, a water inlet pipeline, a water return pipeline, multiple filters and multiple electric control valves; the water distributor It is connected to multiple terminals through the water inlet pipeline, and the water inlet pipeline includes multiple water diversion ports; the water collector is connected to the terminal through the return water pipeline, and the return water pipeline includes multiple water collection ports; the filter is set in the return water pipeline close to the terminal The collection unit includes a plurality of water pressure sensors, and the connection between the water inlet pipe and the water distributor and the terminal, the water distribution port, the connection between the return water pipe and the water collector and the terminal, and the water collection port are all equipped with water pressure sensors. ; Each filter is located between two water pressure sensors; the electric control valve is set in the water inlet pipeline and the water return pipeline. By arranging a plurality of water pressure sensors in the pipeline, and judging whether there is blockage in the pipeline and the location of the blockage according to the pressure difference detected by the water pressure sensors, real-time monitoring of the pipeline is realized.

The invention refers to a heating system (100) comprising a district cooling grid (1) and a local heating system (200) configured to heat a building and / or to heat tap water for the building. The heating system has a feed conduit (5) for an incoming flow of cooling fluid having a first temperature, and a return conduit (8) for a return flow of cooling fluid having a second temperature, the secondtemperature being higher than the first temperature. The local heating system (200) comprises a heat pump (10) having an inlet (10a) connected to the return conduit (8) of the district cooling grid (1) and an outlet (10b) connected to the feed conduit (5) of the district cooling grid (1).

A district cooling type ice-storage tank device comprises a heat-exchanging coil; a bracket is arranged in an ice-storage tank; a plurality of layers of heat-conducting panels are arranged on the bracket along the water surface direction; through holes are evenly designed in the heat-conducting panels for conducting heat exchange between the water at the upper layer and the lower layer; the heat-exchanging coil is inserted in a layer frame structure and the heat-conducting panels; and the heat-conducting panels are vertical to the flow direction of refrigerant in the heat-exchanging coil. As the heat-conducting panels are additionally arranged to conduct incomplete fault segmentation to the water body, on one hand, the temperature difference between the upper water layer and the lower water layer adjacent to the heat-conducting panels at the enhancing layers is reduced; on the other hand, the through holes in the heat-conducting panels can lead the high-temperature water at the bottomof the upper layer thereof and the low-temperature water on the top of the lower layer to be effectively diffused and convected, thereby ensuring the temperature at the upper water layer and the lowerwater layer to be more uniform. In addition, by adopting a vertical heat-exchanging coil with an isometric or unequally spaced design layout to form subsection heat exchange, the heat-exchanging amount at each section at a certain height can be ensured basically the same, and the liquid accumulated in a tube can be effectively avoided, thereby leading the heat exchange to be more uniform.
