  • Patent number: 11982478
    Abstract: An air conditioner includes a refrigerant circuit, sensors that measure an amount representing a state of refrigerant in the refrigerant circuit, and a controller. The controller executes normal operation according to air conditioning load and a first detection operation of detecting refrigerant leakage. The controller adjusts a degree of subcooling at an outlet of the condenser to a first value during normal operation. The controller detects a value related to discharge temperature of the compressor or a value related to degree of superheating at an outlet of the evaporator, based on a sensor measurement result. The controller adjusts degree of subcooling to a second value larger than the first value when executing the first detection operation, and determines that refrigerant is leaking when the value related to discharge temperature of the compressor or the value related to degree of superheating is equal to or larger than a threshold value.

  • Patent number: 11326977
    Abstract: The present disclosure belongs to the field of municipal engineering and urban water supply network, and provides an efficient method for localizing leaks in a districted metering area (DMA) of water supply pipe networks based on valve operations and online water metering, which is implemented in multiple stages to gradually reduce the leaking area. At each stage, the DMA is firstly decomposed into two sub-areas using an optimized valve operation strategy determined by a minimized objective function, wherein a graph theory-based method is used for the solution. Then the sub-areas containing leaks are identified through online water balance analysis based on smart demand meters, thereby reducing the leaking area. The minimum leaking area is identified with the least number of valve operations. Compared with the traditional methods, the method of the present disclosure can obviously improve the efficiency and accuracy of leak localization and is easy to implement.
