Refrigeration system with adiabatic electrostatic cooling device

A CO2 refrigeration system with an adiabatic gas cooler with electrostatically charged cooling spray, comprising:

• a CO2 refrigerant circuit including an evaporator, a compressor, a gas cooler, a receiver, and an expansion valve;
• wherein the gas cooler comprises:
• one or more cooling coils;
• one or more moisture pads adjacent to the one or more cooling coils;
• one or more spray nozzles configured to wet the one or more moisture pads with electrostatically charged water droplets;
• a moisture sensor associated with the one or more moisture pads, operable to provide a signal representative of a moisture level of the one or more moisture pads;
• a controller configured to:
• receive the signal representative of the moisture level of the one or more moisture pads;
• and
• control a supply of water to the one or more moisture pads in response to the signal representative of the moisture level.

A method of providing an evaporative gas cooler for a refrigeration system, comprising:

• providing one or more heat exchanger coils;
• installing a first moisture panel external to the one or more heat exchanger coils;
• installing a second moisture panel external to the one or more heat exchanger coils, the second moisture panel separated from the first moisture panel by a distance;
• installing a first nozzle array external to the first moisture panel;
• configuring the first nozzle array to provide an atomized spray of electrostatically charged droplets to the first moisture panel;
• installing a second nozzle array external to the second moisture panel;
• configuring the second nozzle array to provide an atomized spray of electrostatically charged droplets to the second moisture panel;
• configuring a moisture sensor to provide a signal representative of a moisture level from at least one of the first moisture panel or the second moisture panel;
• providing a controller communicatively coupled to the moisture sensor;
• receiving, by the controller, the signal representative of the moisture level from at least one of the first moisture panel or the second moisture panel;
• and
• controlling, by the controller, a supply of water to at least one of the first moisture panel or the second moisture panel in response to the signal representative of the moisture level.
