Systems and methods are disclosed for a cogeneration system for providing heating, cooling, and/or electricity to an enclosure. The system includes a heat engine for heating and supplying electricity to the enclosure. Coupled to the heat engine is a first conduit configured to transfer fluid from the heat engine to the enclosure to transfer thermal energy from the fluid to the enclosure. The system further includes a heat pump configured to supply at least heating and cooling to the enclosure. Coupled to the heat pump is at least a second conduit. The second conduit is configured to move fluid from the heat pump to the enclosure to transfer thermal energy from the fluid to the enclosure.

A flameless heater includes a diesel engine, a hydraulic or electric load that is powered by the diesel engine thereby generating heat, a heat exchanger that transfers heat to air flowing through the air from the flameless heat source, and possibly other heat exchangers for heating the air flowing therethrough with engine coolant and/or with exhaust gases. The system may be operated to maintain relatively high load on the engine for at least the majority of the time so as to reduce or negate the need for parked regeneration. The system may also control airflow through the system and possibly other system parameters to obtain a given setpoint such as a given discharge air temperature. In one embodiment, airflow through the system is controlled by louvers under the power of an electric motor or other actuator controlled by the system's controller.

Heat from a rotating prime mover(s) driving a fluid shear pump, heat from the prime mover and any exhaust heat generated by the prime mover is collected. The heat energy collected from all of these sources is transmitted through heat exchangers to a fluid where heat energy is desired. This fluid heating process is performed in the absence of an open flame.
