Technical Field

[0002] This disclosure relates generally to gas supply systems, and more specifically to a gas supply system adapted to increase the pressure and / or volumetric flow rate of the supplied gas. background

[0003] Some applications that require a gas (e.g., nitrogen, argon, etc.) or a mixture of gases (e.g., air) as input may require increased pressure and / or volumetric flow rate of the gas or gas mixture supplied to these applications. For example, combustion chambers for turbochargers typically require increased pressure and flow rate of air supplied to the turbocharger to achieve higher horsepower. Similarly, some pipeline applications may require high-pressure air, for example, to complete irrigation system purging, transport bulk products (e.g., flour or limestone) through pipelines, or drive utility traction lines (attached to parachutes) through the pipeline. Some gas supply devices (e.g., compressors, blowers, etc.) are operable to pressurize gases or gas mixtures supplied to downstream applications. However, increasing gas pressure with such devices can be problematic due to temperature limitations. For example, pressurizing air via a single-stage compressor to achieve a high-pressure output (above 30+ psig) may undesirably cause the air temperature to rise above an acceptable threshold, making the air unsuitable for downstream applications, or degrading the function of the compressor (and / or downstream components) due to high-temperature thermal exposure (e.g., thermal fatigue). The aim is to provide pressurized gas or gas mixtures under conditions of increased pressure and flow rate by regulating heat generation. Brief Overview

[0004] The following is a simplified overview of this disclosure to provide a basic understanding of some of the example aspects described in the detailed description. This overview is not exhaustive. Furthermore, this overview is not intended to identify key elements of this disclosure, nor is it intended to define the scope of this disclosure. The sole purpose of this overview is to present some concepts in a simplified form as an introduction to the more detailed explanation that follows.

[0005] The present invention provides (but is not limited to) systems and methods for supplying pressurized gas (e.g., air) to an application.

[0006] According to a non-limiting aspect of the invention, such a multi-stage pressurized gas delivery system includes at least a first gas supply device and a second gas supply device that respectively generate a first pressurized gas output and a second pressurized gas output. The first gas supply device and the second gas supply device are fluidly connected such that the first pressurized gas output and / or the second pressurized gas output can be used to meet the flow and pressure requirements of downstream applications. If only one of the first gas supply device and the second gas supply device is used to meet the application requirements, the first gas supply device and the second gas supply device are connected in parallel (parallel mode), such that operating either the first gas supply device or the second gas supply device generates the system output. If both the first gas supply device and the second gas supply device are used to meet the application requirements, the first gas supply device and the second gas supply device are connected in parallel (parallel mode) to generate and increase the system's volumetric output, or connected in series (series mode) to increase the system's pressure output.

[0026] According to another aspect, a method for generating pressurized gas using a gas delivery system (including a controller operatively connected to a first gas supply device, a control valve, and a second gas supply device) includes: receiving an application input via the controller that defines the system's pressurized gas output; and adjusting the control valve to at least one of a first position or a second position based on the application input.

It should be understood that other embodiments may be utilized, and structural and functional changes may be made, without departing from the corresponding scope of this disclosure. Furthermore, features of various embodiments may be combined or modified without departing from the scope of this disclosure. Therefore, the following description is presented by way of illustration only and should not in any way limit the various alternatives and modifications that may be made to the illustrated embodiments, which remain within the spirit and scope of this disclosure.

[0037] As used herein, the terms “example” and “exemplary” mean instance or illustration. The terms “example” or “exemplary” do not indicate key or preferred aspects or embodiments. Unless the context otherwise suggests, the word “or” is intended to be inclusive, not exclusive. As an example, the phrase “A uses B or C” includes any inclusive permutation (e.g., A uses B; A uses C; or A uses both B and C). As another matter, the articles “a” and “an” are generally intended to mean “one or more” unless the context otherwise suggests. Furthermore, as disclosed herein, the terms “substantially,” “about,” and their variations are intended to indicate that the described feature is equal to or approximately equal to a certain value or characteristic, reflecting tolerances, conversion factors, rounding, measurement errors, and other factors as needed. For example, the term “substantially” is intended to indicate an exact value or characteristic, or a deviation from that exact value or characteristic within 15%, such as within 10% or 5%. As another example, the term "about" can refer to a value that deviates from a specified value by 15%, 10%, or 5%.

[0038] Figure 1An example multi-stage pressurized gas delivery system 10 is schematically illustrated. This system includes components and control logic to allow two or more gas supply units (including, but not limited to, compressors (e.g., variable-speed driven compressors, variable-speed rotary screw compressors, reciprocating compressors (e.g., piston compressors), etc.), blowers (e.g., positive displacement blowers, variable-speed blowers, centrifugal blowers, etc.), boosters, turbochargers, and gas generators (e.g., membrane-based generators, PSA generators)) to operate in parallel or series mode to meet the needs of various applications utilizing pressurized gases. For the purposes of this disclosure, the term "pressurized gas" is intended to refer to a pressurized gas mixture (e.g., air) or other examples of gases, including but not limited to nitrogen, argon, helium, carbon dioxide, and / or any other suitable example or mixture thereof. For convenience, the system 10 described below has two gas supply units: a first gas supply unit 40 for generating a first pressurized gas output and a second gas supply unit 80 for generating a second pressurized gas output. For the purposes of this disclosure, the pressurized gas generated by system 10 (via one or both of the first and second gas supply devices) may be referred to as the system pressurized gas output. Furthermore, the first gas supply device 40 and the second gas supply device 80 may also be referred to as a gas moving supply source, a gas generating supply source, or a gas conveying supply source. In the illustrated embodiment, there are two gas supply devices. It should be understood that system 10 may include more than two gas supply devices that generate pressurized gas and / or supply pressurized gas to the system.

[0039] Each of the first gas supply device 40 and the second gas supply device 80 may be driven (powered) by a driver to increase the pressure and / or flow rate of gas (e.g., air) entering its inlet (e.g., 40a or 80a). For the purposes of this disclosure, the term "driver" is intended to refer to a power unit suitable for driving the gas supply devices 40 and 80, including but not limited to electric motors, hydraulic motors, internal combustion engines, or any other suitable power unit for driving the gas supply devices 40 and 80. In the illustrated embodiment, the first gas supply device 40 is driven by a first driver 42, and the second gas supply device 80 is driven by a second driver 82. In other embodiments, the first gas supply device 40 and the second gas supply device 80 may be driven by a single driver, as discussed in detail below.

[0040] System 10 may include one or more control systems or controllers for individually or jointly controlling gas supply devices 40 and 80. In the illustrated embodiment, system 10 includes a controller 100 operatively connected to a first actuator 42 and a second actuator 82, and a control valve 90 disposed between an outlet 40b of the first gas supply device 40 and an inlet 80a of the second gas supply device 80. In some embodiments, controller 100 may include a processor 102 and a storage device 104. Processor 102 may be configured to perform the disclosed methods and processes for supplying the pressurized gas output of the systems described herein. Processor 102 may be any suitable processing device or set of processing devices, such as, but not limited to, a microprocessor, a microcontroller-based platform, a suitable integrated circuit, one or more field-programmable gate arrays (FPGAs) and / or one or more application-specific integrated circuits (ASICs). Storage device 104 may be volatile memory (e.g., RAM, which may include non-volatile RAM, magnetic RAM, ferroelectric RAM, and any other suitable form); non-volatile memory (e.g., disk storage, flash memory, EPROM, EEPROM, non-volatile solid-state memory, etc.); non-replicable memory (e.g., EPROM); read-only memory; and / or high-capacity storage devices (e.g., hard disk drives, solid-state drives, etc.). In some examples, storage device 104 includes a variety of memories, particularly volatile and non-volatile memories. Storage device 104 may include a computer-readable medium on which one or more sets of instructions (e.g., software for performing one or more pressurized gas supply procedures or methods) may be embedded. The instructions may be embodied in one or more of the methods or logic described herein. In some embodiments, during execution of the instructions, these instructions may reside wholly or at least partially within storage device 104, any one or more of the computer-readable medium, and / or data processor 102.

[0041] The controller 100 can utilize various computing environments to implement aspects of this disclosure, including, for example, a computer, wherein the computer includes a processing unit, system memory, and a system bus. The system bus couples system components, including, but not limited to, coupling storage device 104 to processor 102.

[0042] Furthermore, controller 100 may include or be communicatively coupled to user interface 106, which is operable to receive input and display output regarding the operational status of system 10. Specifically, user interface 106 provides an interface between a user (e.g., an operator) and controller 100. User interface 106 may include digital and / or analog interfaces (e.g., input and output devices) to receive input from the user (e.g., command inputs, such as for selecting between one or more gas application inputs corresponding to one or more gas supply procedures), stop commands, pause commands, start commands, etc. Additionally, user interface 106 may be configured to display system data (discussed below) while system 10 is running in real time.

[0043] Input devices may include, for example, control knobs, buttons, sliders, touchscreens, cameras (for capturing images of tags or QR codes corresponding to the pressurized gas generation process) and / or visual command recognition, audio input devices (e.g., microphones), and / or touchpads. In some embodiments, controller 100 may be communicatively coupled to components of the system via communication component 108. For example, communication component 108 may enable communication between controller 100 and first gas supply device 40 and second gas supply device 80, communication between controller 100 and first actuator 42 and second actuator 82, and communication between controller 100 and control valve 90. Communication component 108 may include physical and / or logical interfaces for connecting controller 100 to components of the system. For example, the communication component 108 can enable Wi-Fi-based communication, such as via frequencies defined by the IEEE 802.11 standard, short-range wireless frequencies (such as Bluetooth®), cellular communication (e.g., 2G, 3G, 6G, 6G LTE, 5G, etc.), or any suitable wired or wireless communication protocol that enables the controller 100 to interface with system components or other systems (e.g., if one or more systems are communicatively coupled to and / or controlled by the controller 100).

[0044] Still referencing Figure 1The first gas supply device 40 and the second gas supply device 80 are represented as each having a filter disposed adjacent to its inlet (e.g., an air inlet), specifically, a first filter 44 disposed adjacent to and connected to the inlet 40a of the first gas supply device 40 (via the first conduit C1), and a second filter 84 disposed adjacent to and connected to the inlet 80a of the second gas supply device 80 (via the second conduit C2). The first filter 44 and the second filter 84 may each be appropriately sized for their respective associated gas supply devices 40 and 80. In some embodiments, the first filter 44 and the second filter 84 may be embodied as air filters (e.g., glass fiber filters, polyester filters, washable filters, pleated filters, and electrostatic filters). In some embodiments, the first filter 44 and the second filter 84 may comprise air filters and / or moisture filters (e.g., any suitable example of an inlet moisture filter or a water collector). In some embodiments, system 10 may not require the first filter 44 and / or the second filter 84, for example, in embodiments where the gas supplied to the first gas supply device and the second gas supply device has been purified (so that the gas can be directly supplied to the inlet 40a of the first device 40 and the inlet 80a of the second device 80, respectively).

[0045] Control valve 90 is an operable device for selectively directing a pressurized gas flow (i.e., a first pressurized gas output) exiting outlet 40b of the first gas supply device 40. Control valve 90 can operate in multiple positions. For example, in a first position, control valve 90 can direct the first pressurized gas output to system outlet 110 via a third conduit C3 connected between outlet 40b of the first gas supply device 40 and control valve 90, and a fourth conduit C4 connected between control valve 90 and system outlet 110. In some embodiments, the third conduit C3 and the fourth conduit C4 can be embodied as a single conduit, wherein control valve 90 separates a first flow path (between outlet 40b and control valve 90) from a second flow path (between control valve 90 and system outlet 110). When control valve 90 is in the first position, system 10 can be referred to as operating in a “parallel mode.”

[0046] In the second position, control valve 90 can direct the first pressurized gas output to the inlet 80a of the second gas supply device 80 via the third conduit C3, the fifth conduit C5 (also referred to as the interstage conduit), and the sixth conduit C6. In some embodiments, the fifth conduit C5 and the sixth conduit C6 can be embodied as a single conduit (as opposed to the two separate conduits connected at connector J1 as shown). When control valve 90 is in the second position, system 10 can be referred to as operating in “series mode”. In this way, control valve 90 is operable to direct flow in parallel mode (e.g., in the first position) or in series mode (e.g., in the second position). Control valve 90 can be appropriately sized for the first pressurized gas output of the first gas supply device 40. In some embodiments, control valve 90 can be operated independently or manually, electrically, or hydraulically under the control of controller 100. In various non-limiting examples, control valve 90 can be embodied as a three-position solenoid valve having an inlet port (connected to the third conduit C3) and a first outlet port and a second outlet port connected to the fourth conduit C4 and the fifth conduit C5, respectively. The control valve 90 can also be operated to prevent pressurized gas (leaving outlet 40b or outlet 80b) from passing through the control valve 90 in a third position, for example, in such embodiments where the control valve 90 is a solenoid valve. In this way, the controller 100 may include logic for operating the control valve 90 in one of the first, second, and third positions based on flow and pressure requirements specified for a given application. In some embodiments, the control valve 90 may take other forms, including, but not limited to, another suitable example of a solenoid valve (having more than three positions, for example, a fourth position for venting to the atmosphere) or a manual valve (e.g., a three-way ball valve or a diverter valve). The control valve 90 can be manipulated (e.g., via the controller 100) such that one or both of the first gas supply device 40 and the second gas supply device 80 supply pressurized gas for a particular application with a desired system pressurized gas output (e.g., a desired flow rate or pressure).

[0047] As described above, when control valve 90 is set to the first position, system 10 is in parallel mode, in which the outlet 40b of the first gas supply device 40 and the outlet 80b of the second gas supply device 80 are fluidly connected to system outlet 110 via the third conduit C3, the fourth conduit C4, and the seventh conduit C7, respectively. Although in some embodiments, in parallel mode, both the first gas supply device 40 and the second gas supply device 80 may not need to operate, for example, when control valve 90 is in the third position to prevent the first pressurized gas output from passing through control valve 90, for example, when it is desired to operate only the second gas supply device 80 to supply its pressurized gas (i.e., the second pressurized gas output) to system outlet 110 (making the second pressurized gas the system pressurized gas output). It is also contemplated that in the first position only the first gas supply device 40 can operate, for example, to supply the first pressurized gas output to system outlet 110 (making the first pressurized gas output the system pressurized gas output), while the second gas supply device 80 is selectively deactivated via controller 100 (e.g., by shutting down the second actuator 82).

[0048] As described above, when control valve 90 is set to the second position, system 10 can operate in a series mode, in which gas supply devices 40 and 80 are fluidly connected via a third conduit C3, a fifth or intermediate conduit C5, and a sixth conduit C6. It should be understood that in some embodiments, gas supply devices 40 and 90 may be fluidly connected only via the third conduit C3 and the intermediate conduit C5, for example, in an embodiment where the intermediate conduit C5 is directly connected to the inlet 80a of the second gas supply device 80. Operating in a series mode can be particularly advantageous for increasing the pressure of the gas supplied from system outlet 110 (i.e., the system pressurized gas output) to a pressure value that would otherwise be impossible to achieve when operating a single gas supply device due to temperature and pressure limitations. For example, the first gas supply device 40 can increase the pressure of the gas (entering its inlet) to a first pressure value (e.g., 15 psig) and supply a first pressurized gas output (at the first pressure value) to the inlet 80a of the second gas supply device 80 to progressively increase the pressure of the first pressurized gas output from the first pressure value to the second pressure value. In this way, in series mode, the second gas supply device 80 may only need to gradually increase the pressure from the first pressure value to a second pressure value corresponding to the desired system pressurized gas output (e.g., 30 psig). This aspect of the disclosure is particularly advantageous for regulating heat generation, as operating a single gas supply device to increase the gas pressure to the second pressure value (e.g., 30 psig) may be impractical, as doing so would undesirably cause the gas temperature to overheat, making it unsuitable for downstream applications or potentially damaging downstream components. In series mode, the first device 40 and the second device 80 can be driven individually (via the first driver 42 and the second driver 82), or by alternative devices (discussed below), such as a single driver discussed in detail below.

[0049] A first valve 60 may be disposed between the second filter 84 and the inlet 80a of the second gas supply device 80. In the illustrated embodiment, the first valve 60 is disposed on the second conduit C2, upstream of the joint J1 between the fifth conduit C5 and the sixth conduit C6. The first valve 60 may unidirectionally allow gas to flow from the filter 84 to the inlet 80a of the second gas supply device 80 while preventing flow in the opposite direction, i.e., preventing gas from flowing back to the filter. In some embodiments, the first valve 60 may be embodied as a check valve, or a manually or electronically controlled shut-off valve, such as a ball valve, butterfly valve, gate valve, or electrically actuated ball valve or solenoid valve. When the system 10 is switched to series operation, a first pressurized gas output (via control valve 90) is directed to the second gas supply device 80, and the first valve 60 may be actuated (via controller 100) to prevent gas from flowing to the second filter 84.

[0050] System 10 may also include a second valve 62 to prevent the first pressurized gas output from flowing back to the second gas supply device 80, for example, when system 10 is operating in parallel mode (e.g., when control valve 90 is in the first position and the first gas supply device 40 is operated to supply the system pressurized gas output). In some embodiments, the second valve 62 may be used to prevent the system pressurized gas output from flowing back toward the second gas supply device 80, for example, if there is an obstruction in the seventh conduit C7, or if a downstream pressure vessel (configured to store the system pressurized gas output) drains the system pressurized gas output toward the second gas supply device 80, for example, due to a rupture or other malfunction. System 10 may also include a third valve 64 configured to prevent the second pressurized gas output from flowing back to the first gas supply device 40. However, it is contemplated that control valve 90 may be used to prevent the second pressurized gas output from flowing back to the first gas supply device 40, thus eliminating the need for the third valve 64. Furthermore, in series mode, it is contemplated that control valve 90 may prevent the first pressurized gas output from flowing through the fourth conduit C4 toward the second gas supply device 80, thus eliminating the need for the second valve 62. In some embodiments, the second valve 62 and the third valve 64 may be embodied as electronically or manually controlled shut-off valves or check valves, such as any suitable example of shut-off valves or check valves disclosed herein. In some embodiments, the controller 100 may include logic for opening or closing the first valve 60, the second valve 62, and the third valve 64 based on a particular supply scheme or mode of operation (e.g., parallel mode or series mode).

[0051] Given the aforementioned arrangement of System 10, aspects should be obvious, including the following non-limiting aspects.

[0052] System 10 may include two or more gas supply devices 40 and 80 fluidly connected, such that the output of any or both of the gas supply devices 40 and 80 can be used by the application to meet its requirements. If only one of the two gas supply devices 40 or 80 is desired or required to meet the application's requirements, the gas supply devices 40 and 80 may be connected in parallel (i.e., in parallel mode) and either gas supply device 40 or 80 may be operated to produce the output of system 10. If both gas supply devices 40 or 80 are desired or required to meet the application's requirements, devices 40 and 80 may be connected in parallel (i.e., in parallel mode) and both devices 40 and 80 may be operated simultaneously to produce and increase the volumetric output of system 10. Alternatively, gas supply devices 40 and 80 may be connected in series and operated (i.e., in series mode) to generate gas pressure and increase it to the desired system pressurized gas output at system outlet 110.

[0053] In some embodiments, the system is capable of producing a positive air displacement of greater than 0.0 cubic feet per minute (cfm) at a positive pressure greater than 0.5 psig.

[0054] In some embodiments, the gas supply devices 40 and 80 may be any one or more of the following positive displacement and / or positive pressure generating devices: compressor, positive displacement blower, centrifugal blower, booster, gas generator, and turbocharger, etc.

[0055] Furthermore, system 10 may include at least one control valve 90 for switching between parallel and series modes, wherein, in series mode, the output of the first gas supply device 40 is connected to the inlet of the second gas supply device 80.

[0056] Figure 1 The system 10 shown can operate as a standalone system, and can also be operated in conjunction with other systems of similar properties to increase overall pressurized gas generation. In this scenario, at least one additional control valve can be used to align the output of one system with the inlet of (multiple) other systems.

[0057] The system may further include an aftercooler to reduce the overall discharge temperature of the pressurized gas generated by the system. The system may further include an interstage cooler between the first gas supply device 40 and the second gas supply device 80 to reduce the temperature of the pressurized gas when the system operates in series, wherein the discharge gas from the first gas supply device 40 is supplied to the inlet 80a of the second gas supply device 80.

[0058] The system may include devices (e.g., check valves, ball valves, gate valves, shut-off valves, etc.) for preventing pressurized gas from flowing back from the first gas supply device 40 to the second gas supply device 80, or for example, preventing pressurized gas from flowing back from the second gas supply device 80 to the first gas supply device 40 when the system is operated to use a single gas supply device in the first device 40 and the second device 80, and / or preventing pressurized gas supplied by the second gas supply device 80 from flowing to the control valve 90 and the first gas supply device 40 when the devices 40 and 80 are operated simultaneously in series.

[0059] The system may include one or more control devices (e.g., controller 100 as shown in the figure) for controlling the system to utilize the output of a single device in the first gas supply device 40 and the second gas supply device 80, or to utilize the output of both the first gas supply device 40 and the second gas supply device 80 when operating the system 10 in parallel or series mode.

[0060] The system may utilize controls that monitor the system's safety parameters (e.g., pressure, flow rate, temperature). In some embodiments, the controls may be embodied as pressure switches, pressure regulators, pressure sensors, temperature sensors, flow control valves, pressure gauges or temperature gauges, and indicator lights. The system may include logic for actuating these controls via electronic methods (e.g., computer-readable instructions), such as, but not limited to, integrated software.

[0061] The system and its devices 40 and 80 can be driven by an external power source, such as, but not limited to, an electric drive system containing an electric motor, a hydraulic drive system, or an internal combustion engine.

[0062] The system can pair two (or more) gas supply units 40 and 80 with the same air output parameters, or pair two (or more) units 40 and 80 with different air output parameters.

[0063] The system can pair two (or more) gas supply units 40 and 80 that operate using the same mechanical compression method, or pair two (or more) units 40 and 80 that operate using different mechanical compression methods.

[0064] The system may include an overpressure safety device, the size of which is determined for the end-use application.

[0065] Gas supply devices 40 and 80 can be driven by gear or belt drives, gearboxes and / or direct drive units to ensure that devices 40 and 80 operate at appropriate speeds (revolutions per minute, rpm).

[0066] The system may include devices for reducing gas pulsation, such as one or both of gas supply devices 40 and 80, or those desired or required by the application supplied by the system. Furthermore, the system may utilize any suitable conduit for conveying or delivering pressurized gas through or from it, such as hoses (e.g., high-temperature silicone hoses, air hoses, or hydraulic hoses), pipes, tubes, or any other suitable form for conveying a particular type of pressurized gas supplied therefrom.

[0067] Turn now Figure 2Another example of a multi-stage pressurized gas delivery system 200 is shown. Similar reference numerals will be used to depict similar features. Furthermore, for brevity, descriptions of similar features have been omitted. In the illustrated embodiment, a first temperature sensor 292 and a first pressure sensor 294 are respectively disposed between the outlet 240b of the first gas supply device 240 and the control valve 290 to monitor the temperature and pressure of the first pressurized gas output and transmit the corresponding temperature and pressure data (e.g., in real time) to the controller 300. The first temperature sensor 292 and the first pressure sensor 294 can take any suitable form. For example, the temperature sensor 292 can be embodied as a thermistor, a temperature transducer, a thermocouple, a resistance temperature detector (RTD), a semiconductor-based sensor, and / or any other suitable example configured to measure the temperature of gas supplied through a conduit. Furthermore, the pressure sensor 294 can take any suitable form, such as a strain gauge, pressure transducer, piezoresistive pressure sensor, inductive pressure sensor, capacitive pressure sensor, and / or any other suitable example configured to measure the pressure of gas supplied through the conduit. The first pressure relief valve 250 can also be located between the control valve 290 and the outlet 240b of the first gas supply device 240. The pressure relief valve 250 is operable to limit the gas pressure in the conduit from exceeding a predetermined maximum pressure value, for example, a predetermined maximum pressure value that could damage the system (e.g., components downstream of the first pressure relief valve 250). The pressure relief valve 250 can take any suitable form, such as a spring-loaded pressure relief valve, a pilot-operated pressure relief valve, a temperature-activated pressure relief valve, a piston-type relief valve, a diaphragm-type relief valve, or any other suitable example thereof.

[0068] A first cooler 254 may be disposed between valve 290 and outlet 240b of the first gas supply device 240 to cool the first pressurized gas output. The first cooler 254 may take any suitable form, such as an electric cooler (driven by a power unit, e.g., a motor), a fan, an air-cooled aftercooler, a radiator, etc. In some embodiments, the first cooler 254 may be fluidly connected to a first tap 270 (e.g., a mechanically or electrically actuated valve, such as a two-way solenoid valve) operable to drain accumulated moisture from the first cooler 254, for example, during system shutdown. It is contemplated that, for example, the first cooler 254 may be actuated manually or via controller 300 when the temperature of the first pressurized gas output exceeds a maximum temperature value (as measured via the first temperature sensor 292). Maintaining the temperature of the pressurized gas in this manner advantageously eliminates the possibility of damage to downstream components (e.g., control valve 290, the second device 280 in series mode, or components receiving gas from system outlet 310) due to high temperature / heat exposure.

[0069] Still referencing Figure 2 A second temperature sensor 295 and a second pressure sensor 297 may be respectively disposed between the outlet 280b of the second gas supply device 280 and the control valve 290 to monitor the temperature and pressure of the second pressurized gas output and provide the corresponding temperature and pressure data (e.g., in real time) to the controller 300. The second temperature sensor 295 and the second pressure sensor 297 may take any suitable form, such as any suitable example disclosed herein. A second pressure relief valve 252 may be disposed between the control valve 290 and the outlet 280b of the second gas supply device 280. The second pressure relief valve 252 is operable to limit the amount of pressure in the conduit, for example, to avoid exceeding a maximum pressure value (when exceeded) that would damage the system (e.g., components downstream of the second pressure relief valve 252). The second pressure relief valve 252 may take any suitable form, such as any suitable example disclosed herein. A second cooler 256 may be disposed between the valve 290 and the outlet 280b of the first gas supply device 240. It is envisioned that, for example, when the temperature of the second pressurized gas output exceeds a maximum temperature value (as measured via the second temperature sensor 295), the second cooler 256 can be actuated manually or via the controller 300. Maintaining the temperature of the pressurized gas in this manner helps to eliminate the possibility of damage to downstream components (e.g., components receiving pressurized gas from system outlet 310) due to high temperature / heat exposure. The second cooler 256 can take any suitable form, such as any suitable example disclosed herein. In some embodiments, the second cooler 256 can be fluidly connected to a second tap 272. The second tap 272 can be embodied as a mechanically or electronically actuated valve (e.g., a two-way valve) operable to drain accumulated moisture from the second cooler 256, for example, during system shutdown.

[0070] A third temperature sensor 296 and a third pressure sensor 298 may be respectively disposed on the in-stage conduit C5 to monitor (e.g., in series mode) the temperature and pressure of the first pressurized gas output supplied from the first gas supply unit 240 (via control valve 290) to the second gas supply unit 280. The third temperature sensor 296 and the third pressure sensor 298 may provide the corresponding temperature and pressure data to the controller 300 to balance the load between the first gas supply unit 240 and the second gas supply unit 280 during series mode operation (e.g., to prevent one or both of the devices from overheating), as discussed in detail below. Furthermore, a water separator 258 may be disposed on the in-stage conduit C5 to remove ambient moisture from the first pressurized gas output (e.g., compressed air) supplied from the first gas supply unit 240 to the second gas supply unit 280. The water separator 256 may take any suitable form, such as a centrifugal water separator, a gravity-operated water separator, a moisture filter containing a desiccant (e.g., silica gel), etc. In some embodiments, another water separator may be configured adjacent to system outlet 310 to remove moisture from the system pressurized gas output before it is supplied to downstream applications via system outlet 310 (in order to limit the amount of moisture introduced into downstream applications).

[0071] Turn now Figure 3An example drive 500 according to another embodiment will now be described. In this embodiment, drive 500 is a single drive configured to power a first gas supply device 440 and a second gas supply device 480. Drive 500 can be configured to independently control the rotational speed (revolutions per minute, RPM) of the first gas supply device 440 and the second gas supply device 480, for example, the rotational speed of their associated pressurized gas generating elements (e.g., rotating screw elements, rotors, blades, impellers, reciprocating pistons, etc.). Specifically, drive 500 may include a motor 501 configured to power a first continuously variable transmission (CVT) 502 and a second CVT 504 associated with the first gas supply device 440 and the second gas supply device 480, respectively. The first CVT 502 may include a first pulley 502a and a second pulley 502b rotatably coupled via an intermediate belt 502c. The first pulley 502a may embody a master clutch, and the second pulley 502b may embody a driven clutch. When the main pulley 502a (via motor 501) rotates and engages with belt 502c, it causes the driven pulley 502b to rotate, thereby causing the pressurized gas generating element of the first device 440 to rotate to generate pressurized gas based on the specific pressure and flow requirements of the application. Similarly, the second CVT 504 may include elements similar to those of the first CVT 502 to independently control the rotational speed of the second device 480 and its pressurized gas generating element. Therefore, for the sake of brevity, a description of similar elements is omitted.

[0072] Referring to Figure 4, now we will refer to Figure 2 The example system 200 is used to describe an example method of the operating system. Although it should be understood that the following description may also be applied to other systems falling within the scope of this disclosure, such as system 100 or systems utilizing different driver configurations (e.g., Figure 3 The system of the driver 500. At step 602, the controller 300 may receive a gas application input, which includes instructions for providing a pressurized gas output for a system, for example, instructions for achieving a predetermined flow rate or pressure requirement at system outlet 310. In some embodiments, the gas application input may be via the user interface 306 of the controller 300 ( Figure 2The gas application input can be selected. For example, the gas application input can define system pressurized gas output data for a specific gas application input, such as 5 psig air for 200 cfm of a 6" pipe, 9 psig air for 175 cfm of a 4" pipe, 1 psig air for 125 cfm of a 3" pipe, or 30 psig air for 50 cfm of a 4" pipe. At step 604, the controller 300 may include logic for adjusting system settings based on the gas application input to produce a system pressurized gas output. For example, the controller 300 may set the control valve 290 to an appropriate position (e.g., a first position or a second position) to achieve a specific pressure and / or flow rate specified by the gas application input. For example, to supply 50 cfm at 30 psig for a 4" pipe, controller 300 can set the position of control valve 290 to a second position to activate a "tandem mode". In this configuration, the first pressurized gas output of the first gas supply unit 240 (via the intrastage conduit C5) is routed to the second gas supply unit 280 to achieve a 30 psig target (high pressure requirement), which cannot be achieved, for example, by operating only one of the first gas supply unit 240 and the second gas supply unit 280, due to the output pressure and temperature limitations of a single gas supply unit as discussed above. In this way, various examples of multistage pressurized gas delivery systems disclosed herein enable the generation of higher-pressure pressurized gas by regulating heat generation through the operation of two or more units in series (i.e., by distributing the system load between two units rather than on a single unit). In some embodiments, it is envisioned that more than two gas supply units in series may exist, for example, to further increase the maximum output pressure capability of the system (e.g., from 30 psig of two gas supply units to even higher pressures of three gas supply units operating in series mode).

[0073] At step 604, in some embodiments, controller 300 may adjust control valve 290 and / or other system 200 components based on control logic or instructions (e.g., software stored in a storage device) to achieve a system pressurized gas output (i.e., the pressure and flow rate requirements specified by the gas application input). For example, controller 300 may set second valve 260 to a closed position (e.g., in series mode) to prevent the first pressurized gas output from flowing back to second filter 284. In some embodiments, at step 604, controller 300 may adjust control valve 300 to a parallel mode (e.g., a first position), for example, when it is desired to supply the cumulative output from both first gas supply device 240 and second gas supply device 280 to achieve a higher volumetric flow rate requirement (where the first and second gas supply devices will equalize pressure to increase flow), or when it is desired to operate only one of the first and second devices (e.g., to achieve a lower pressure and / or volumetric flow rate requirement). For example, controller 300 can receive a gas application input that defines a system pressurized gas output of 200 cfm at 5 psig for a 6" pipe. To achieve this flow rate (high flow requirement), controller 300 can set control valve 290 to a first position such that a first pressurized gas output supplied from a first device 240 is directly supplied to air outlet 310, and a second pressurized gas output supplied from a second device 280 is directly supplied to air outlet 310 to obtain the system pressurized gas output, i.e., the 200 cfm flow requirement. In some embodiments, it is envisioned that more than two devices can be operated in parallel, for example, to increase the system's volumetric flow rate capacity (e.g., from 200 cfm to even higher flow rates).

[0074] At step 606, the controller may include components for operating the system to implement logic for pressurized gas output. For example, the controller may operate one or both of the first gas supply device 240 and the second gas supply device 260 to generate a specific system pressurized gas output corresponding to a gas application input. In some embodiments, the controller 300 may set the rotational speeds of drivers 242 and 282 (e.g., motors) such that the drivers rotate the pressurized gas generating elements (e.g., blades, rotors, rotary screws, impellers, reciprocating pistons, etc.) of the first gas supply device 240 and the second gas supply device 280 to achieve system pressurized gas output (e.g., the pressure and flow rate of gas supplied from system outlet 310). When using a single driver (e.g., Figure 3 In an embodiment where the controller 300 (500) provides power to the first and second devices, the controller 300 can set the rotational speeds of CVT 502 and 504 to achieve pressurized gas output from the system.

[0075] At step 608, controller 300 may receive system data, including but not limited to pressure data (e.g., from pressure sensors 294, 297, and 298), temperature data (e.g., from temperature sensors 292, 295, and 296), flow rate data (e.g., via flow meters disposed on the outlet sides of the first and second devices), and humidity data (e.g., from a humidity sensor configured to sense the moisture content of pressurized gas supplied from one or both of the first device 240 and the second device 280). This aspect of the disclosure is particularly advantageous for controlling or otherwise adjusting the system in a manner that takes into account the current operating conditions of the system in real time (step 610). For example, at step 610, controller 300 may receive system data and then adjust system components (e.g., first device 240 and second device 280, first cooler 254 and second cooler 256, first tap 270 and second tap 282, first valve and second valve, etc.) based on the system data. Figure 1 60 and 64 in the middle, or Figure 2 (260) to obtain the system pressurized gas output (for a specific gas input) while taking into account the current operating conditions of the system. For example, controller 300 may receive temperature data (e.g., from temperature sensor 291) indicating that the temperature of the first pressurized gas output supplied from the first device 240 has exceeded a maximum predetermined threshold indicating a system problem (that needs further investigation). In response, at step 610, controller 300 may deactivate the first device 240 (e.g., by turning off the first drive 242 or shutting down the entire system). In another non-limiting example, controller 300 may receive pressure data (e.g., from pressure sensor 294) indicating that the gas pressure supplied from the first device 240 has exceeded a maximum predetermined threshold. In response, controller 300 may adjust drive 242 (e.g., reduce motor speed) (in real time) to reduce the pressure to an acceptable range or target value defined by the gas input. While the foregoing examples refer to the first drive 240, it should be understood that the foregoing examples are also applicable to the second drive 280.

[0076] When operating in series mode (at step 612), controller 300 can also receive system data (e.g., pressure and temperature data) (i.e., intrastage pressure and intrastage temperature values) from third pressure sensor 298 and third temperature sensor 296. Controller 300 can use the intrastage pressure and intrastage temperature values ​​to balance the load between the first gas supply unit 240 and the second gas supply unit 280, for example, to prevent the second gas supply unit from overheating or overpressurizing. For example, if the intrastage pressure and temperature values ​​exceed predetermined values ​​(e.g., 7 psig, 350 degrees Fahrenheit), controller 300 can (e.g., via first drive 242) reduce the rotational speed of the first gas supply unit 240 to bring the intrastage pressure and temperature back to an acceptable range or target value, for example, to prevent the introduction of a first pressurized gas output (exceeding the temperature or pressure threshold) from the first gas supply unit 240 into the second gas supply unit 280. Monitoring the stage pressure and temperature can also help prevent overpressure of the second gas supply unit 280, for example, by controlling the rotational speed of the first gas supply unit (e.g., the rotational speed of its corresponding pressurized gas generating element) to prevent the introduction of high-pressure gas (as input to the second gas supply unit) that could damage internal components of the second gas supply unit, or by affecting efficiency by blowing some of the first pressurized gas output through the gas pressure generating elements (e.g., rotors, blades, etc.) of the second gas supply unit. Similarly, supplying low-pressure gas to the inlet of the second gas supply unit may result in insufficient gas supply (e.g., creating a vacuum), thus affecting the efficiency of generating the second pressurized gas output. It is also envisioned that the controller 300 can adjust the rotational speed of the second gas supply unit 280 (alone or together with the rotational speed of the first gas supply unit 240) to obtain target interstage pressure and stage temperature suitable for the specific application.

[0077] At step 610, it is also envisioned that the controller 300 can activate or adjust other system components to obtain the system pressurized gas output. For example, the controller 300 can activate the cooler 254 to control the intrastage temperature of the first pressurized gas output supplied from the first gas supply device to the second gas supply device in series mode. In some embodiments, the controller 300 can reduce the rotational speed of the first gas supply device 240 based on intrastage pressure and temperature values ​​exceeding target values. In some embodiments, if the gas pressure and temperature (monitored via temperature sensor 295 and pressure sensor 297) exceed predetermined values, the controller 300 can reduce the rotational speed of the second gas supply device 280. In some embodiments, the controller 300 can activate the first cooler 254 to bring the temperature of the second pressurized gas output supplied from the second gas supply device 280 (measured by sensor 295) back to an acceptable target value. In another non-limiting example, controller 300 may actuate one or both of the first cooler 254 and the second cooler 256 to control the temperature of the system pressurized gas output supplied from system outlet 310 based on temperature measurements (e.g., based on temperature measurements from temperature sensors 292 or 295 in parallel mode, or from sensors 292, 295 and 296 in series mode).

[0078] In some embodiments, for example, if the pressure and / or flow rate (cfm) values ​​(e.g., measured by a temperature sensor and a flow meter) are below certain target values, the controller 300 may also increase the rotational speed of the first drive 240 and / or the second drive 280. In this way, it should be understood that a wide variety of system adjustments can be made based on system data to achieve the desired system pressurized gas output.

[0079] While the invention has been illustrated by describing embodiments thereof, and while these embodiments have been described in considerable detail, it is not intended that the scope of the appended claims be limited or in any way restricted to such details. Further advantages and modifications will be readily apparent to those skilled in the art. For example, it is contemplated that multiple systems can be operated to generate a total pressurized gas output (for a given application), which derives from the respective pressurized gas outputs of the multiple systems. Furthermore, it is contemplated that the arrangement of system components may differ from that shown in the illustrated examples, for example, by placing temperature sensors, pressure sensors, coolers, pressure relief valves, or other system components in locations different from those shown. Therefore, the invention, in its broader aspects, is not limited to the specific details, representative devices, and illustrative examples shown and described. Thus, deviations from these details are possible without departing from the spirit and scope of the applicant's overall inventive concept.
