Document Type and Number:
Japanese Patent JP2020204412
Kind Code:
A
Abstract:
To provide an absorption type refrigerator capable of reducing an unnecessary operation of a control motor operating a fuel control valve and improving durability of the control motor even when sliding of the fuel control valve causes operation variation.SOLUTION: An absorption type refrigerator includes a high-temperature regenerator 5, a low-temperature regenerator 6, an evaporator 1, a condenser 7 and an absorber 2, and these devices are connected by piping, to form respective circulation passages of an absorbent and a refrigerant. An actual opening value of a fuel control valve 64 is compared with a fuel control valve opening calculated value, and on the basis of a difference between the values, sensitivity width of an opening of the fuel control valve 64 is corrected and fed back to an opening control section 91, so as to enable control within a dead zone and enable improvement of durability of a control motor 92 of the fuel control valve 64.SELECTED DRAWING: Figure 5
