  • Publication number: 20200292440
    Abstract: A test device and method for top-of-the-line corrosion (TLC) of a high-temperature high-pressure wet gas pipeline. The device mainly includes: a metal top cap, a metal reaction cylinder, a first thermometer, a second thermometer, a plastic transparent measuring cylinder, a condensed water collection tube, an atomic spectrometer, a third thermometer, a rubber seal cover, a condensate droplet, a threaded hole, a condensation chamber, a pipeline sample, a temperature measuring hole, and a 30-degree tilt angle. The device and method can effectively simulate TLC of a wet gas pipeline under a high-temperature high-pressure environment. The device and method can test the high-temperature high-pressure TLC of the wet gas pipeline under different temperature differences (between a surface temperature of the pipeline and a gas temperature) and various corrosion media.

  • Publication number: 20200208890
    Abstract: A defrosting control method for a multi-split system is provided. A multi-split system comprises an outdoor unit and multiple indoor units. An expansion valve is provided on a connecting pipeline between each of the indoor units and the outdoor unit. When the expansion valve of each activated indoor unit is closed and the degree of opening of the expansion valve of each off-state indoor unit is less than or equal to a maximum set degree of opening, the system satisfies a defrosting requirement, and as a result the method controls the expansion valve of each activated indoor unit to remain closed, thereby resolving the issue of a dramatic temperature drop in a room having an activated indoor unit during defrosting and improving user satisfaction. The degree of opening of the expansion valve of a off-state indoor unit is Off_PLS, and is controlled such that Off_PLS=ALL_HP*Avg_PLS/Off_HP.

  • Publication number: 20200191430
    Abstract: The present disclosure discloses a method and a device for controlling an expansion valve. The method includes: when a first specified number of indoor units are in a non-working state, turning off expansion valves corresponding to all the indoor units in the non-working state; and turning on expansion valves corresponding to a second specified number of indoor units in the non-working state in turn according to a predetermined cycle.

  • Patent number: 10318931
    Abstract: The present invention discloses a method and system for determining a maintenance policy of a complex forming device. The method and system include: establishing a performance judgement standard; obtaining actual operation data; and determining a performance stage of the complex forming device, and determining the maintenance policy of the complex forming device. The establishing a performance judgement standard includes allocating data located at different performance stages to corresponding working condition units; setting data located at a normal performance stage to normal reference data, and calculating, by using a shortest path algorithm, distances between operation data of different working condition units in different functional modules and the normal reference data, to obtain performance statuses of the different functional modules.
