Title:
DIGITAL COOLING CONTROL SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/149135
Kind Code:
A1
Abstract:
The present invention proposes a system that can produce a significant energy saving effect in the operation of refrigeration cycle devices, such as an air conditioning device, a freezer device, a refrigeration device, a freezer, a refrigerator, and a vending machine, and in particular, a refrigeration cycle device that includes, as a constituent element, an outdoor unit provided with a compressor. The present invention is constituted by a digital cooling device and a digital cooling control device. The digital cooling device comprises: a blower fan; a diffused-water cooling mat disposed between the blower fan and an air intake part of an outdoor unit; a water deflection damper disposed between the diffused-water cooling mat and the air intake part; and a digital anemometer disposed between the water deflection damper and the air intake part. The digital cooling control device comprises: a refrigeration cycle device operation coefficient calculation means for calculating an operation coefficient for a refrigeration cycle device; a water supply control means for executing water supply control for starting water supply or stopping water supply with respect to the diffused-water cooling mat, such control executed when the calculated operation coefficient reaches a prescribed operation coefficient value or when an outdoor temperature, from a digital outdoor temperature sensor provided to the outside of the outdoor unit, reaches a prescribed outdoor temperature value; and a blowing control means for executing blowing control for causing the blower fan to operate so as to generate a flow of air in the direction toward the air intake part, or for causing the operation of the blower fan to stop so as to stop the flow of air in the direction toward the air intake part.
