| 20130284817 | FLAMELESS HEATING SYSTEM - A mobile heating system is disclosed. In one embodiment, the system includes an enclosure defining a plenum that houses a fan and an internal combustion engine. The heating system also includes a hydraulic circuit including a hydraulic pump operably coupled to the internal combustion engine and a first heat exchanger located in the plenum and in fluid communication with the hydraulic pump. The hydraulic circuit also includes a hydraulic motor operably coupled to the fan wherein the hydraulic motor is in fluid communication with and driven by the hydraulic pump. A first valve is disposed between the hydraulic pump and the heat exchanger and is configured to restrict fluid flow and to increase a fluid pumping pressure of the hydraulic pump. A second valve is located upstream of the first valve and is configured to selectively direct hydraulic fluid between the first valve and the hydraulic motor. | 10-31-2013 |
| 20140216437 | HYDRONIC SURFACE HEATING SYSTEM - A mobile surface heater is disclosed having a heat generation loop and a heat dissipation loop. The heat generation loop can include a heat generating device, a storage tank, and a first pump for circulating a fluid. The heat dissipation loop can be placed in fluid communication with the heat generation loop and includes a ground heating system having at least one heat transfer conduit extending between a supply manifold and a return manifold. A control valve can also be provided to deliver a mixed fluid flow stream to the ground heating system by selectively mixing fluid from the heat generation loop with fluid returning from the ground heating system return manifold. In one embodiment, an electronic controller is provided that operates the mixing valve to maintain a temperature setpoint of the mixed fluid flow stream and to maintain a minimum entering fluid temperature setpoint of the atmospheric water heater. | 08-07-2014 |
