Latest Patents

One of his latest patents is a control system for commercial refrigeration systems. This invention features a compressor control system that includes a variable speed compressor alongside multiple fixed speed compressors. The control system calculates a variable that fluctuates according to the desired capacity of the system, based on the difference between the refrigeration load and a target value. A PID (proportional-integral-differential) controller is utilized, incorporating terms that fluctuate based on the square of the difference between the sensed variable and the target value, as well as the second derivative of the control variable over time. This allows for precise control of the refrigeration capacity by adjusting the speed of the variable speed compressor and managing the operation of fixed speed compressors.

Another notable patent is for an island type refrigeration display cabinet. This design features a top aperture with two oppositely disposed louvers that discharge air curtain sections to create a single air curtain. The cabinet is equipped with a system for withdrawing air from the interior and forcing it through a bifurcated conduit, which is connected to the respective louvers. This innovative design also includes means for refrigerating the air flowing through the conduit, enhancing the display and preservation of products within the cabinet.
