Title: Valve opening control method
Inventor: TAMAKOSHI KOICHIRO
IPC: F16K31/04
Filed: 1988-11-26
Abstract: PURPOSE:To control the valve opening without producing errors by transforming forcibly a valve opening data in a memory means to a valve opening data decreased or increased by an amount of data corresponding to a unit movement. CONSTITUTION:An expansion valve 9 in an outdoor machine 3 is controlled by regulating the pressure of refrigerant up or down the expansion valve 9. These pressures are detected by pressure detectors 17 and 18. The detected pressure data are transmitted to an indoor machine 2 and transformed to the data for controlling the valve opening of the expansion valve 9 in it. Then the data is returned back to the outdoor machine 3. The degree of opening of the valve provided in the flow line of the fluid is controlled for each unit movement between the upper and lower limits, according to deviation between the given control data and the valve opening data memorized by a memory means. A data after subtracting the deviation from the memorized valve opening data is then memorized again in the memory means. The valve opening data in the memory means is transformed forcibly to the valve opening data decreased or increased by an amount of data corresponding to the unit movement.
