The invention relates to an adsorption refrigerator or an adsorption heat pump as well as a method for the operation thereof. The adsorption refrigerator or adsorption heat pump comprises at least one module having an adsorber, a mixing evaporator and a mixing condenser. It is characterized in that the adsorber together with the mixing evaporator and the mixing condenser within the module is structurally combined and contained within a common, preferably thermally insulated adsorber container for accommodating the adsorber and having an adsorber section which can be thermally contacted externally, and having a mixing section thermally insulated externally for accommodating the mixing evaporator and the mixing condenser, wherein the mixing section is formed so that a refrigerant can flow through it, so that the refrigerant, after having flown through the mixing section, can be supplied to an external heat exchanger that is separated from the module, wherein the mixing section is arranged to enable the refrigerant to be evaporated and/or condensed.

Technologies are described herein for cooling systems. In some examples, a cooling system uses cooling cells to provide cooling to a space. The cells can include one or more adsorption chambers, whereby an adsorbent in the adsorption chamber causes a refrigerant (such as water) to evaporate. The action of evaporation removes heat from a cooling fluid, which is used to cool the space.

Provided is a condensate water trap for a gas furnace that collects and discharges condensate water produced in a heat exchanger and an exhaust pipe. The condensate water trap includes: a first inlet through which the condensate water produced in the heat exchanger is introduced; a second inlet through which the condensate water produced in the exhaust pipe is introduced; a first flow path through which the condensate water coming from the first inlet passes; a second flow path through which the condensate water coming from the second inlet passes; an outlet through which the condensate water introduced through the first and second inlets is discharged; a third flow path into which the residual condensate water passed through at least one of the first and second flow paths but not discharged through the outlet is introduced; and a sensing mechanism that senses if the amount of residual condensate water introduced into the third flow path is greater than or equal to a given amount.

The invention is related to a heat exchanger collector configuration (1) allowing more efficient heat distribution within double-helix heat exchangers of heating systems by connecting the outer helix (14) with the inner helix (13) and minimizing the heat loss of water circulating within the helices. Thanks to the heat exchanger collector configuration (1), the inner helix (13) can be connected to the outer helix (14) without any deformation on its full circular structure. As the full circular structure of the inner helix (13) is not deformed, heat formed within the combustion chamber inside of the inner helix (13) is distributed equally over the helix and thereby, efficiency of heat absorption is increased.

This heating system consists of a ceiling or wall mounted housing containing a fan, motor, electric heater and optional controller which connects to a discharge vent via a duct which can all fit within a wall. It has primary usages as a room or shower heater where it can be recessed into a wall or ceiling where it intakes air from the room, heats it and routes it through an insulated duct in the wall and vents it back into the room near the floor. In a shower, the heater can be located high on the wall or in the ceiling away from the shower to keep it away from splashed water. Additionally, the heater and vent can both be mounted in the ceiling where the heater is outside the shower and the vent is in the shower. It can be controlled by a switch, wired thermostat or wireless remote.

A heat source device including a sheet-metal burner body (30), a fan casing (40) connected to the burner body (30), an annular packing (90) connecting a burner-side connection end surface (340) with a fan-side connection end surface (410) in an airtight state, a sheet-metal connection part (80) disposed between the burner-side connection end surface (340) and the fan-side connection end surface (410), wherein the connection part has an opening (85) and a packing storage portion (84) storing the annular packing (90), wherein the opening (85) is provided in such a manner that an opening edge is positioned outside of those of an inlet port (35) and a blowout port (44) in a state where the connection part (80) is disposed between the burner-side connection end surface (340) and the fan-side connection end surface (410).

An electrocaloric fiber includes an electrocaloric material surrounding a centrally located electrode. The electrocaloric fiber may further include an outer electrode surrounding the electrocaloric material. The electrocaloric fiber may be used to form an electrocaloric fabric.

The present disclosure discloses a combustion chamber and a combustion apparatus. The combustion chamber includes: a first surrounding plate located on an outer side and a second surrounding plate located on an inner side. A combustion cavity is defined by the second surrounding plate. The first surrounding plate and the second surrounding plate are spaced apart from each other to define at least one air duct in communication with the combustion cavity. Each of the at least one air duct has an air inlet hole formed in the first surrounding plate, and an air outlet hole formed in the second surrounding plate.

An apparatus can comprise a circuit and an electrical element coupled to the circuit. The circuit can include a pulse generator to generate an electrical pulse having a first power and a load. The electrical element can be configured to receive heat that is converted into electrical energy by the circuit to apply a second power, greater than the first power, to the load.
