The invention relates to a method for operating a sorption system (), the sorption system comprising the following: a cooling fluid circuit (), which has a cooling fluid; a process medium circuit (), which has a refrigerant and a solvent; an absorber (), which is connected to the cooling fluid circuit () and to the process medium circuit (); a condenser (), which is connected to the cooling fluid circuit () and to the process medium circuit (); and a control device. During operation of the sorption system (), the cooling fluid is fed to the absorber () and to the condenser (), and a feed of the cooling fluid to the absorber () and a feed of the cooling fluid to the condenser () are controlled differently from each other by means of the control device. The invention further relates to an arrangement for a sorption system () and to a sorpotion system ().

Sorption system and method for operating same

The invention relates to a heat exchanger unit having an evaporator device configured for evaporating a heat exchanger operating fluid, and a condenser device for condensing the heat exchanger operating fluid, wherein the evaporator device and the condenser device are fluidically connected to each other in a frontal configuration. The invention further relates to a thermotechnical system having a plurality of heat exchanger units.

Heat exchanger unit and thermotechnical system

The application relates to a liquid distributor () for supplying a liquid in a pressure-free manner over a surface area, having a distributor trough () with a trough base () which, for the purpose of discharging liquid, has an arrangement of holes (), which extends over at least part of the surface of the trough base (), having an inflow (), via which a liquid which is to be distributed can be introduced in the distributor trough () such that the liquid introduced accumulates on the trough base (), and having a retaining device with a retaining plate (), which is arranged opposite the trough base () and at a distance apart therefrom, wherein distributing elements (), which project from the retaining plate () in the direction of the trough base (), each engage through an associated hole of the arrangement of holes () in the trough base () and are accommodated loosely therein such that the liquid accumulating on the trough base () can be discharged through free hole regions (), which are not affected by the distributing elements () extending through the holes ().

Liquid distributor and arrangement

The invention relates to a method for operating a cooling system, in which a cooling agent is prepared in a reservoir of an evaporator device () of a single- or multi-stage sorption cooling system, a fluid to be cooled is cooled by having a heat exchanger of the evaporator device () effect a cooling heat transfer from the fluid to be cooled to the cooling agent for cooling purposes, and the cooling heat transfer causes the cooling agent to at least partially evaporate on the heat exchanger, and the evaporated cooling agent is relayed to a liquefier device (), wherein the cooling heat transfer is improved by conveying external thermal energy provided by an external heat source () to the cooling agent, specifically in addition to and separately from the cooling heat transfer, and thereby initiating bubble formation that supports cooling heat transfer in the cooling agent in the reservoir, specifically by inducing bubble formation in conjunction with supplying the external thermal energy or intensifying bubble formation triggered by the cooling heat transfer. In addition, the invention relates to a cooling system in single- or multi-state configuration.
