摘要:
The invention relates to a heat pump according to the adsorption principle, comprising a plurality of hollow elements each having an adsorbent, wherein a working medium is enclosed in each of the hollow elements is displaceable between the adsorbent and a phase change area, wherein a heat-transporting fluid in a variable fluid circuit can flow through the hollow elements by means of a valve arrangement. The hollow elements are brought into thermal contact with the fluid in the area of the adsorbent, wherein the flow through the hollow elements changes cyclically with the fluid, wherein at least two of the hollow elements are flown through parallel from the fluid at least in one, in particular each position of the valve arrangement, and at least two of the hollow elements are flown through serially one after the other.

The invention concerns a device for compressing gaseous media comprising at least one compression chamber (10) into which the gaseous medium can enter and from which the gaseous medium can exit, and comprising a first valve device (13, 7) having at least one first opening (13) and at least one first covering device (7) that essentially covers the first opening at least intermittently. The first valve device permits the gaseous medium to enter the compression chamber (10) and prevents, in essence, the gaseous medium from exiting the compression chamber (10). The inventive device also comprises a second valve device (4, 8) having at least one second opening (4) and at least one second covering device (8) that essentially covers the second opening at least intermittently. The second valve device permits the gaseous medium to exit the compression chamber (10) and prevents, in essence, the gaseous medium from entering the compression chamber (10). To this end, the narrowest free cross-section of one valve device considerably exceeds the narrowest free cross-section of the other valve device.

An air conditioning system has a refrigerant cycle, a coolant cycle, a refrigerant/coolant heat exchanger, coupling these cycles so as to transfer heat, and a valve for operating mode-dependent control of the refrigerant flow, whereby the air conditioning system can be operated not only in air conditioning mode but also in a heat pump or reheat mode. An internal combustion engine exhaust gas/coolant heat exchanger is connected upstream in series to the refrigerant/coolant heat exchanger in the coolant cycle in the heat pump mode; and/or in the reheat operating mode the refrigerant/coolant heat exchanger functions as a condenser/gas cooler, connected upstream in series on the coolant side to the supply air/coolant heat exchanger. In addition or as an alternative, a drying operating mode can be provided for drying the supply air/refrigerant heat exchanger with reversed air conveying direction.

A desorbable sorption filter, in particular for a heating or air-conditioning system of a motor vehicle, has a metallic support (12) which can be heated by flow of current and an adsorber (14) mounted at or on the support (12). To provide an improved, directly heatable sorption filter which particularly enables inexpensive production and good electrical and thermal conductive contact without the use of adhesives, it is proposed for the adsorber (14) to be of planar design and to be mechanically connected to the support (12, 112) by means of holding elements (26) formed integrally on the support (12, 112).

A rotating valve includes an inlet region, an outlet region, and a switching region having a switching member that can be rotated about an axis. In a first position of the switching member the plurality of inlets are connected to the plurality of outlets in a first association, and in a second position of the switching member the plurality of inlets are connected to the plurality of outlets in a second association. The switching member has a plurality of openings through which the fluid flows flow axially in the direction of the rotation axis and are moved together with the switching member. The openings alternately cover a plurality of stationary, axially directed openings in the course of the rotation of the switching member. Different associations of the inlets with the outlets are carried out by the alternating covering of the axially directed openings.

摘要:
heating pump is provided that has a plurality of heat transfer devices, each having at least one first zone and one second zone for displacing an operating resource arranged in the heat transfer device based on thermodynamic state variables. Each of the heat transfer devices are thermally connectable by the first zone thereof to a first flow channel through which a first fluid can flow and by a second zone thereof to a second flow channel through which a second fluid can flow, so that heat energy can be exchanged between one of the fluids and one of the zones. The flow channels of one of the zones can be interconnected to one another sequentially by a valve arrangement and an interconnecting sequence changes in the course of an operation of the heat pump by the valve arrangement.
