Title:
エンジン駆動冷媒圧送循環式熱移動装置におけるエンジンの加速制御方法
Document Type and Number:
Japanese Patent JP4199861
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To maintain a stable operation state without stopping an engine by detecting load fluctuation quantity in a refrigerant circuit, and increasing supply fuel quantity to the engine and/or advancing ignition timing when the load fluctuation quantity is not less than a prescribed value. SOLUTION: In a thermal transfer device for driving compressors 2A, 2B in an outdoor unit by an engine 40 in a heat pump and a refrigerator, a control part 71 judges whether or not a correction factor inferred from a differential value of a deviation of an engine speed exceeds a ceiling value, and when it is judged as YES, a parameter J for expressing shortage quantity is calculated. Next, an acceleration correction value TF to a fuel control valve is calculated by multiplying this parameter J by a preset fuel control valve acceleration basic opening increasing value F to control the fuel control valve 48 by a signal by adding this TF to a fuel control valve opening signal to thereby perform proper acceleration control without stopping an angine at suddent increase time of load.
