Title: Operating method for heat pump
Inventor: HATTORI HISASHI
IPC: F04B49/10
Filed: 1992-02-21
Abstract: PURPOSE:To prevent poor lubrication and seizing due to the lack of lubrication oil by forcibly make an inverter driven compressor run at a low frequency for a fixed time and then make it run at the required frequency again in the case where it run at a high frequency for the specified time or longer. CONSTITUTION:While heating operation is conducted, the high temperature and pressure gaseous refrigerant discharged from the inverter drive compressor 1 of an outdoor unit 22 flows into an oil separator 17 through a discharge pipe 14, for being separated from oil. The separated oil returns to a compressor 1 through an oil returning pipe 19 and the fixed throttle 20 attached to the returning pipe 19. In addition, the refrigerant gas flows into the utilization side heat exchanger 6 of an indoor unit 23 radiates heat to the air in the room becoming high pressure liquid refrigerant. The inverter 21 of a compressor 1 is controlled by a controller 25 based on the detection signal of a pressure sensor 27. In this case, after the compressor 1 continuously runs at a high frequency for a specified time or longer (Step (5) Yes), it is forcibly made to run at a low frequency for a fixed time [Steps (6) and (7)], and then, it runs at a required frequency (3) again.

Title: Adaptive controller
Inventor: ITO OSAMU
IPC: G05B13/02
Filed: 1989-03-23
Abstract: PURPOSE:To generate an adaptive controller with simple constitution by obtaining the 'sum value' of the influence of an unknown parameter and installing a control variable arithmetic output means which negates an unknown dynamic characteristic through the use of a 'processed sum value'. CONSTITUTION:An arithmetic means 4 obtains the influence of the unknown parameter which is to be controlled as the 'sum value' at respective times. Then, the obtained sum value is processed in a mark processing means 5 in such a way that it can be used in the control rule. Finally, the control variable arithmetic output means 3 controls the unknown characteristic which is to be controlled while it is negated by using the 'processed sum value'. Since the influence of the unknown parameter is obtained as the 'sum value', the number of unknown quantities which are to be obtained considerably reduces, and accordingly the constitution of the adaptive controller can considerably be simplified.
