The invention relates to a method for cyclical operation of a thermoelectric cell arrangement by periodically changing the temperature of the thermoelectric cell arrangement, wherein the thermoelectric cell arrangement is thermally coupled to a cyclically operated absorption heat pump. The following method steps are carried out cyclically: thermally coupling the thermoelectric cell arrangement during a cooling phase to a cold side of the absorption heat pump, thermally coupling the thermoelectric cell arrangement during a heating phase to a hot side of the absorption heat pump. The invention also relates to a harvester device for generating electrical energy by means of a thermoelectric cell arrangement, wherein the thermoelectric cell arrangement is thermally coupled to an absorption heat pump, wherein the thermal coupling makes it possible to effect, in time with the working cycle of the absorption heat pump, a temperature change in the thermoelectric cell arrangement.

According to one example of the present invention, a cooling system is provided. The cooling system comprises a water-cooled air conditioning module for cooling air from a chamber. The chamber is arranged for receiving air to be cooled and hot humid air. The cooling system also comprises a control system for controlling the flow of hot humid air to the chamber such that the air input to the air conditioning module has a predetermined relative humidity level within a predetermined range.

A sorption module for a sorption temperature-control device may include a housing enclosing a working chamber. A sorption zone and a phase change zone may be arranged in the working chamber where a working medium is displaceable reversibly between the sorption zone and the phase change zone. A sorption structure may be arranged in the sorption zone, and a phase change structure may be arranged in the phase change zone. An outer wall of the housing may include a double-walled section that may provide a cavity between an outer wall part and an inner wall part of the double-walled section, and the phase change zone may be arranged on an inner side of the inner wall part.

Features for distributing a sorber gas in cooling, heating or refrigeration systems with sorbers are disclosed. The sorbers may adsorb gas onto a sorbent material and desorb gas therefrom. Distribution of the gas to and from the sorber may be done with porous, rigid tubes. The tubes may be formed of composite material having pores. The pores may be implemented by flowing fluids through the composite material while the material cures. The sorbers may be reinforced with rods to provide greater strength and stability in load-inducing environments. The tubes may extend through the sorbent and thereby provide a channel for the gas to flow to and from the sorbent and the rest of the cooling, heating or refrigeration system.

In one aspect, a refrigeration system is provided. The refrigeration system includes a refrigeration circuit configured to condition an air supply, a subcooling circuit configured to cool the refrigeration circuit, the subcooling circuit including a subcooling condenser, a subcooling heat exchanger, and at least one adsorption bed, and a heat generation system thermally coupled to the subcooling circuit.

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.
