An air-conditioning system which may be included in a motor vehicle may include a single pair of tube-and-plate heat exchangers arranged within a common vacuum enclosure, the heat exchangers selectively coupled with a heat source, a radiator, and an air-conditioning core. During an adsorbing/evaporating mode, coolant may circulate between a first heat exchanger and the radiator and vapor may evaporate from the surface of non-adsorbent-coated plates of the second heat exchanger and be adsorbed at adsorbent-coated plates of the first heat exchanger while coolant circulates between the second heat exchanger and the core. During a desorbing/condensing mode, coolant may circulate between a heat source and the first heat exchanger to effect desorption of vapor from the adsorbent in the first heat exchanger, while melting PCM in the core exchanges heat with air blown through the core to provide cooling.

A method and device for cooling and/or heating media, preferably in a motor vehicle, the method in which at least one first heat source is cooled and at least one second heat sink is heated by a thermal management system. In a method in which the heating or cooling can occur on demand, heat and/or cold are shifted by the thermal management system in space and time to the heat sink and/or heat source, which is characterized by need.

The subject of this invention is a method of heat transfer in the embedded structure of a heat regenerator and the design thereof. It regards the related heat regenerators, which operate on the principle of the described method and enable a reduction of the pressure drop due to the fluid flow through the heat regenerator and consequently an increase of the power density. The concept of the operation of the heat regenerator by this invention, in which for the oscillation of the flow of the primary (first) fluid (P), electromechanical elements are applied. In the housing (1) between the elements (2) for the oscillation of the primary (first) fluid (P), there are positioned a primary hot heat exchanger (PT) and a primary cold heat exchanger (PH). In the direction of the arrow (A) the unidirectional flow of the secondary (second) fluid (S) flows from the heat sink into the primary cold heat exchanger (PH). In the direction of the arrow (B) the unidirectional flow of the secondary (second) fluid (S) exits from the primary cold heat exchanger (PH) and flows towards the heat source. Meanwhile, in the direction of the arrow (C), the unidirectional flow of the secondary (second) fluid S enters the primary hot heat exchanger (PT) and exits in the direction of the arrow (D) as the unidirectional flow of the secondary (second) fluid S of the primary hot heat exchanger (PT) towards the heat sink. Between both primary heat exchangers, (PT) and (PH), the porous regenerative material is positioned, which is part of the regenerator 4, with the hydraulically separated segments.
