Patent JP-2001056159-A (JP)
Title: Air conditioner
Inventor: YABU TOMOHIRO
IPC: F25B13/00
Filed: 1999-12-16
Abstract: PROBLEM TO BE SOLVED: To prevent the drop of a room temperature by continuing a heating run while running a defrost run by arranging a pair of compressors in a coolant circuit and by feeding the discharged coolant from one compressor to an outdoor heat exchanger and the discharged coolant from the other compressor to an indoor heat exchanger. SOLUTION: In the heating run, the gas coolant discharged from a first compressor 11a is further compressed by a second compressor 11b and heats indoor air flowing into each indoor heat exchanger 13. A liquid coolant, having flowed out from the heat exchanger 13, flows into a coolant heat exchanger 15, merges with the coolant from the first compressor after being sucked into the second compressor and is compressed to high pressure. The high-pressure liquid coolant is turned to a two-phase gas-liquid coolant and vaporized by heat exchanging with the air flowing into the outdoor heat exchanger 17. The vaporized gas coolant flows out from the heat exchanger 17 and is sucked into the first compressor. The above cycle is repeated and the heating run is performed.  When the heat exchanger 17 is frosted with it, the first heat exchanger runs the defrosting run and the second compressor runs the heating run.

Abstract: PURPOSE:To demagnetize a magnetic core without providing a special AC damped oscillation circuit by changing over the direction of an electric current, applied to a bias coil for switching a current measuring range to large and small, to positive or negative in accordance with lead-in of a change-over signal. CONSTITUTION:The device is set within a small current measuring range according to a current applied to a bias coil 45. When an overcurrent flows in an electric wire to be measured at the time of measurement in the small current measuring range, a voltage in accordance with the overcurrent is generated in a Hall element 2, amplified by an amplifier 31 and an excessive output current based on the overcurrent flows in a feedback coil 4 and outputted from an output terminal Iout. A magnetic core is magnetized by the overcurrent. A comparison circuit 33 generates a detection signal when the overcurrent exceeds an upper limit value in a measuring current range. According to this detection signal, a change-over signal is generated from an AND circuit 37 via a flip-flop circuit 34 to instantaneously change over the measuring range to a large current measuring range, and therefore the magnetic core is demagnetized and an offset error of the current measuring device is eliminated.
