Patents by Inventor Matthew Hans Truax

Matthew Hans Truax has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • CONTROL OF REFRIGERATION AND HEAT PUMP SYSTEMS THAT INCLUDE PRESSURE EXCHANGERS
    Publication number: 20230288101
    Abstract: A system includes a pressure exchanger (PX). The PX is coupled to a motor that controls an operating speed of the PX. The system further includes a condenser. An outlet of the condenser is fluidly coupled to a first inlet of the PX. The system further includes a pressure gauge. The pressure gauge is configured to provide first pressure data. The first pressure data is indicative of a pressure of a fluid of the condenser. The system further includes a first controller configured to cause the motor to adjust the operating speed of the PX. The first controller causes the motor to adjust the operating speed of the PX based on the first pressure data.

  • Control of refrigeration and heat pump systems that include pressure exchangers
    Patent number: 11692743
    Abstract: A system includes a pressure exchanger (PX). The PX is coupled to a motor that controls an operating speed of the PX. The system further includes a first pressure gauge configured to generate first pressure data indicative of a pressure of a fluid of a condenser. A first controller is to generate a first control signal based on the first pressure data. The motor of the PX is configured to adjust the operating speed of the PX based on the first control signal. The system further includes a pump. The system further includes a fluid density sensor for generating fluid density data associated with a first output fluid of the PX. A second controller is to generate a second control signal based on at least the fluid density data. The pump is to adjust an operating speed of the pump based on the second control signal.
