Abstract: Examples of the present disclosure relate to systems and methods for providing hot water for a hot water heater and heating capacity for a climate control system by utilizing a Stirling heat pump system. The Stirling heat pump may be partially integrated into an indoor unit of the climate control system and a hot water heater. An additional indoor heat exchanger may receive heating fluid from the Stirling heat pump system to provide heating capacity in addition to another indoor heat exchanger of the climate control system. Further, the heating fluid circuit of the Stirling heat pump system may be partially integrated into a hot water tank for heating water. A controller may direct the flow of heating fluid from the Stirling heat pump to the hot water tank and/or the climate control system based on a request for heating.

Abstract: A compressor unit of a cryogenic refrigeration device includes a compression chamber that is connectable via a transfer line to an expander unit. A piston is configured to alternately compress and decompress a gaseous working agent in the compression chamber. An electromagnetic actuator includes a stator assembly with a driving coil that is wound about the longitudinal axis and that is enclosed within a toroidal back iron except for a coaxial cylindrical gap in a radially outward facing surface. A movable assembly connected to the piston includes two movable permanent magnets separated by a ferromagnetic spacer radially exterior to the stator assembly. The movable magnets are magnetized parallel to the longitudinal axis and opposite to one another such that an alternating electrical current in the driving coil causes the movable assembly to parallel to the longitudinal axis to periodically drive the piston into and out of the compression chamber.

Abstract: A single-acting (two pistons) or double-acting (four pistons) alpha configuration Stirling engine has increased thermal exchange between a hot piston crown and a hot head and between a cold piston crown and a cold head of each piston cylinder assembly, increasing conversion of thermal energy to mechanical motion. The thermal exchange is provided by presenting corresponding transverse peaks and valley that create increased surface area and increased convective fluid flow rate for a working gas sealed in the Stirling engine.

Abstract: Heat regenerators and related methods enable heat transfer in an embedded structure of a heat regenerator. The heat regenerators enable a reduction of the pressure drop due to fluid flow through the heat regenerator and consequently an increase of power density. A heat regenerator includes a housing having a primary hot heat exchanger and a primary cold heat exchanger between elements for the oscillation of a primary fluid. The secondary fluid unidirectionally flows from the heat sink into the primary cold heat exchanger. The secondary fluid exits from the primary cold heat exchanger and unidirectionally flows towards the heat source. The secondary fluid S enters the primary hot heat exchanger and exits as the unidirectional flow of the secondary fluid S of the primary hot heat exchanger towards the heat sink. Between both primary heat exchangers, the porous regenerative material is positioned as part of the regenerator.

Abstract: Multi-spectral methods and systems for the day and night remote sensing (detection, identification, and quantification) of greenhouse gas emission sources from space are provided. The sensor system includes a telescope assembly that passively collects light from an observation area and directs that light through spectral, optical filters and to a sensor array having a plurality of rows and columns of pixels. Different groups of sensor array pixel rows are aligned to receive light that has passed through different optical filters. The filters have passbands corresponding to the reflective and emissive bands of gases of interest, as well as associated reflective and emissive reference bands, and broadband spectral bands. A set of image data frames is obtained as the field of view of the sensor system moves over an observation area and an aggregate image showing locations of detected gas emissions is generated using the collected data.
