Title:
CONTROL METHOD OF STEAM COMPRESSION TYPE REFRIGERATION CYCLE, AND REFRIGERATION DEVICE USING THE SAME
Document Type and Number:
Japanese Patent JP2018036017
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a control method of a steam compression type refrigeration cycle capable of accurately estimating high pressure and low pressure to enable appropriate refrigeration control, and a refrigeration device using the control method.SOLUTION: In a control method of a steam compression type refrigeration cycle in a refrigeration device 10, until each value of refrigerant pressure and suction dryness degree Xs on an unknown side is converged, a control unit 40 is configured to repeat first calculation of setting values of the refrigerant pressure and suction dryness degree Xs on an unknown side, and second calculation of correcting setting values of the refrigerant pressure and/or suction dryness degree Xs on the unknown side, thereby improving accuracy for estimation.SELECTED DRAWING: Figure 3
