Title: Method for cleaning air conditioner indoor unit and outdoor unit
Inventor: ZHANG MINGJIE
IPC: F25B47/02
Filed: 2017-10-26
Granted: 2021-08-17
Abstract: The present invention discloses a method for cleaning an air conditioner indoor unit and outdoor unit. The method includes: controlling a to-be-cleaned heat exchanger to enter a self-cleaning mode; adjusting an operating frequency of an air conditioner, an opening of a throttling device, and a corresponding fan speed of the to-be-cleaned heat exchanger, and maintaining an evaporating temperature of the to-be-cleaned heat exchanger within a present range, so as to enable a surface of the to-be-cleaned heat exchanger to frost; keeping the to-be-cleaned heat exchanger frosting for a time of t1; detecting whether a differential pressure between a high pressure and a low pressure of the air conditioner meets a preset condition; when the differential pressure between the high pressure and the low pressure of the air conditioner meets the preset condition, controlling a four-way valve to change a direction, so as to perform a defrosting switching to indoor and outdoor heat exchangers; and when the differential pressure between the high pressure and the low pressure of the air conditioner does not meet the preset condition, adjusting an operating parameter of the air conditioner to enable the differential pressure between the high pressure and the low pressure of the air conditioner to meet the preset condition, and then controlling the four-way valve to change the direction, so as to perform a defrosting switching to the indoor and outdoor heat exchangers. A direction change of the four-way valve may be controlled by detecting whether the differential pressure between the high pressure and the low pressure of the air conditioner meets the preset condition. Therefore, a great shock to the compressor because of an excessive differential pressure between the high pressure and the low pressure of the air conditioner may be avoided.

Title: Testing method of detecting the defective memory cell in programmable devices
Inventor: HUKUYAMA DOSITAKA
IPC: G11C29/00
Filed: 1986-09-09
Granted: 1990-08-24
Abstract: The method involves the switching of current between a first cell to be tested, and a second cell. The first cell is an unwritten-in cell and the second a written-in cell. A variation in voltage induced across the first cell within a given time period after the switching of current is detected. The detected variation of the voltage is compared with a given threshold level, whereby if the voltage variation is lower than the threshold level, a faulty cell is indicated. The detection of the voltage variation is carried out at an output terminal through at least one comparator. This converts the varying voltage of an analogue signal to a binary output signal, whereby the variation of voltage is measured by an external testing device.
