  • Publication number: 20240384904
    Abstract: An air conditioning system is provided. The system has a high-pressure pipe, a low-pressure pipe, an indoor heat exchanger, an outdoor heat exchanger, a leak-free thermal expansion valve and a variable capacity compressor. The variable capacity compressor has a shell, a first cylinder and a second cylinder. The shell has a suction port and an exhaust port. The first cylinder has a first suction hole connected to the suction port and a first exhaust hole connected to the exhaust port. The second cylinder has a second suction hole connected to the suction port, a second exhaust hole connected to the exhaust port, and a pressure relief hole connected to the high-pressure pipe and the low-pressure pipe in an on-off manner. Before the variable capacity compressor is started, the high-pressure pipe and the low-pressure pipe are connected and also disconnected after the first preset duration.

  • Publication number: 20190166457
    Abstract: System and method for generating location-based alerts. An alert generation server communicates with official alert systems and a plurality of mobile devices operating a mobile alert application. The alert generation server receives alert data from the official alert systems and defines a plurality of alert events by extracting corresponding alert location information and assigning official alert types to the alerts in the received official alert data. The alert generation server also receives user-generated alert data defining alert events identified by mobile device users. The user-generated alert data is used to update and/or modify the defined alert events. Each alert event has a geographic region code corresponding to extracted alert location information. The mobile alert application determines, based on mobile device location data that the mobile device is within the geographic region of an alert event and generates an alert notification for that mobile device.

  • Publication number: 20110296865
    Abstract: A hybrid-driven cold/heat storage type heat pump unit utilizing a solar photovoltaic power and a commercial power, which has a DC compressor (2) and an AC compressor (8), is a dual supply heat pump system driven by a solar photovoltaic DC power and a common commercial AC power in combination. When there is sunshine, the DC generated by a solar cell panel (60) is used for driving the DC compressor (2) directly to produce cold and heat capacity, and the produced cold and heat capacity could be stored respectively in a phase-change cold storage medium (39) and a phase-change heat storage medium (20). When the DC power is insufficient, the AC power from power network is used for power supply.
