The present disclosure relates to a gas engine heat pump including: an engine which burns a mixed air of air and fuel; a first charger which compresses the mixed air and supplies to the engine; a first exhaust flow path which is connected to the engine, and through which exhaust gas discharged from the engine flows; and a second charger which is driven by the exhaust gas branched from the first exhaust flow path to a second exhaust flow path, and compresses the exhaust gas discharged from the engine and supplies the compressed exhaust gas to the engine, thereby reducing the emission of nitrogen oxide by recirculating the exhaust gas without additional power consumption.

Degassing device for degassing a liquid flow, including: a housing for receiving liquid from the liquid flow therein, the housing having one or more ports for connecting to the liquid flow; a valve arranged for allowing gas to escape from the housing; and a heater arranged at least partly inside the housing for raising a temperature of the liquid received in the housing with respect to a further temperature of the liquid flow.

A micro-climate control system includes a thermoelectric system integrated with a fan assembly. The thermoelectric system is operable to actively cool or heat air as the air passes through the fan assembly. The thermoelectric system includes a thermoelectric heat pump, a heat reject subsystem, and a heat accept subsystem. The fan assembly is operable to draw air from a space to be conditioned and output conditioned air passed through one of the heat reject subsystem and the heat accept subsystem to the space to be conditioned and output air passed through the other away from the space to be conditioned. In this way, the micro-climate control system may provide localized comfort, while allowing a larger climate control system to maintain a more efficient temperature set point. In this way, the overall energy consumption may be reduced while providing the same level of effective comfort.

One disclosed system includes: (a) a fan directing an initial air stream to a heater with sufficient heating capacity to heat said initial airstream to a temperature of 200° C. to 350° C. and output a heated air stream; and (b) an air to air heat exchanger positioned and configured to use said heated air stream to preheat said initial airstream prior to its arrival at said heater. Additional systems and corresponding methods are disclosed.

The purification system comprises a heat pump and the heat pump comprises a refrigerant condenser, a refrigerant evaporator, a compressor, and a throttle valve that are fluidly connected with a circulating refrigerant along a refrigerant line. The circulating refrigerant transfers heat to a contaminated feedstock at the refrigerant condenser to vaporize at least a portion of the contaminated feedstock. Also disclosed are methods of purifying water, washing systems comprising a washer and a water purification system, washing and drying systems comprising a washer, a dryer, and a water purification system, and methods for cleaning and/or drying of clothes.

A waste air flow capture system, comprising: a) a cylindrical shroud configured to receive a waste air flow from a waste air flow channel of an HVAC compressor or a heat pump compressor and configured to vent the waste air flow received from the waste air flow channel of an HVAC compressor or a heat pump compressor; b) a first electrical generator configured to generate electricity when a first fan blade assembly rotates relative to the cylindrical shroud and/or a second electrical generator configured to generate electricity when a first fan blade assembly rotates relative to the cylindrical shroud; and d) a first fan blade assembly enclosed by the cylindrical shroud and coupled to the first electrical generator motor on a first side of the first fan blade assembly and coupled to the second electrical generator motor on a second side of the first fan blade assembly.

The present invention relates to a dishwasher comprising a body; a tub; a drying pocket disposed at least one lateral wall of the tub, that is in thermal contact with the tub and that provides the condensation of the humid air inside the tub by being cooled in the drying step; a heat pump disposed inside the body, that provides the heating of the water to be used in the washing step and that has a first heat exchanger drawing heat from the ambient air, a second heat exchanger transferring the heat received from the first heat exchanger to the wash water and a compressor fluidly connected to the first heat exchanger and the second heat exchanger, realizing the refrigerant cycle, and a drip tray disposed immediately under the first heat exchanger, wherein the water condensing on the first heat exchanger is collected.

Envisaged is a regeneration system for a metal hydride heat pump of a damper type. The system comprises a plurality of reactor assembly modules configured to act as a heat pump, an ambient air inlet and a fluid recirculation circuit. The plurality of reactor assembly modules includes first, second, third and fourth metal hydride reactor assembly modules. The fluid recirculation circuit comprises a mixer, a fluid stream switching means, a flow regulating means and an exhaust outlet. The mixer is adapted to mix a portion of a recirculation stream received from the exhaust outlet and the exhaust gas stream to provide a resultant stream. The fluid stream switching means is coupled to the mixer and is adapted to switch flow of the resultant stream as received from the mixer and the ambient air stream in a cyclic manner in a series of half-cycles of operation.
