Control method and device of air conditioner and air conditioner

The invention provides a control method and device of an air conditioner and the air conditioner. The control method of the air conditioner comprises the steps that in the condition that the air condition is in a refrigeration mode or a dehumidification mode, when the air conditioner is shut down or subjected to timing shutdown, the operation time of a compressor is detected; the operation time is compared with a first preset threshold and a second preset threshold; when the operation time is larger than the first preset threshold and smaller than or equal to the second preset threshold, the indoor environment temperature T1 and humidity RH and the temperature T2 of an evaporator coil are detected; the dew-point temperature T<dew> is calculated according to the indoor environment temperature T1 and humidity RH; whether the temperature T2 of the evaporator coil is smaller than the dew-point temperature T<dew> or not is judged; when the judgment result is yes, the air conditioner is controlled to start a drying and mould proof mode; and when the judgment result is no, the air conditioner is controlled to be shut down directly; and the first preset threshold is smaller than the second preset threshold. By means of the technical scheme, whether the drying and mould proof mode function is started is judged automatically, so that the air conditioner is more intelligent and humanized.

Method and system for controlling the initiation and duration of overtime intervals in electronic auctions

InactiveUS7283980B2Increase competitionMaximize competitive natureFinanceCommerceSpecific timeDuration time
A method and system for conducting electronic auctions is described. A dynamic lot closing extension feature avoids collisions in closing times of multiple lots by dynamically extending the closing time of a subsequent lot if a preceding lot's closing time is extended to be too close to the subsequent lot's then-currently scheduled closing time. Scheduled closing times can be extended with a flexible overtime feature, in which the properties of the event triggering the extension and the duration of the overtime period(s) can be tailored to a particular auction, particular lots of products within an auction, and to the particular time within an auction process. The bidding status of a lot can be set to a “pending” status after the nominal closing time for submission of bids to allow bidders to alert the auction coordinator of technical problems in submission of bids. This allows the possibility for a lot to be return to open status for further bidding by all bidders. The auction may be paused by the auction coordinator to correct technical, market and miscellaneous problems that may arise during the course of an auction. Individual bid ceilings can be set for each bidder so that they are required to bid lower than certain thresholds determined in advance of the auction. Failsafe error detection is performed to prevent erroneous bids from entering the auction. The auction coordinator has the ability to override any erroneous bids that are entered to prevent prejudice to the auction.
