Butterfly fan inlet and chamber exhaust valve controllers for wave making systems

A system for generating waves in a wave pool, the system comprising:

• a pool containing water;
• a plenum;
• a plurality of fans in communication with the plenum;
• a power consumption sensor in communication with each of the plurality of fans;
• a chamber located along a first wall of the pool and in fluid communication with the pool and in communication with the plenum, wherein the chamber has a set of valves in communication with the plenum and one or more actuator-controlled gas intake valves and one or more actuator-controlled gas exhaust valves;
• and
• a control system in communication with the power consumption sensor, each of the plurality of fans, and the set of valves;
• wherein the power consumption sensor is operable to measure and send to the control system, in real time, a measurement of the power consumption for one or more of the plurality of fans;
• and
• wherein the control system is constructed to perform the following steps:
• calculate a target power consumption for one or more of the plurality of fans;
• calculate a differential between actual power consumption and the target power consumption for each of the one or more of the plurality of fans;
• calculate a target airflow to be evacuated from the chamber to reach the target power consumption of each of the one or more of the plurality of fans;
• selectively adjust the one or more actuator-controlled gas exhaust valves to the calculated exhaust valve angle for the exhaust valve to achieve the calculated target power consumption;
• and
• selectively open the one or more actuator-controlled gas intake valves to allow air to enter the chamber from the plenum at a controlled rate in order to transfer water out of the chamber into the pool to create a wave.

A method for generating waves in a wave pool, comprising:

• operating a chamber comprising a set of valves wherein the set of valves comprises one or more of an actuator-controlled gas intake valve and one or more of an actuator-controlled gas exhaust valve, and further wherein the chamber is in fluid communication with a pool containing water;
• operating one or more fans in communication with a plenum correspondingly associated with the chamber wherein each of the one or more fans is operable to blow air into the plenum,
• detecting a surge, via a power consumption sensor, for at least one fan of the one or more fans, wherein the power consumption sensor is in communication with the fan of the one or more fans;
• wherein a control system is in communication with the power consumption sensor, and the at least one fan and the set of valves;
• calculating, using the control system:
• a target power consumption for the at least one fan of the one or more fans;
• a differential between the actual power consumption and the target power consumption for the at least one fan;
• a target airflow to be evacuated from the chamber to reach the target power consumption for each of the one or more fans;
• and
• an exhaust valve angle for the gas exhaust valve operable to allow the target airflow to escape from the chamber;
• an intake valve angle for the gas intake valve operable to allow the target airflow to enter the chamber from the plenum;
• selectively adjusting the actuator-controlled gas exhaust valve to the calculated exhaust valve angle to achieve the calculated target power consumption;
• and
• selectively adjusting the actuator-controlled gas intake valve to the calculated intake valve angle to allow air from the plenum to enter the chamber operable at a controlled rate to expel water from the chamber into the wave pool to create a wave in the wave pool.
