Device for heat transfer between a liquid and a gas and method for operating the device

Abstract

A device for heat transfer between a liquid and a gas, having: a gas inlet for providing the gas into an exchange region, a gas outlet for retrieving the gas from the exchange region, a liquid inlet connected to a reservoir for holding the liquid. The reservoir is formed with an opening in an upper region of the reservoir, the reservoir is arranged at an upper end of the exchange region, an impounding basin. The impounding basin is arranged below the reservoir, the impounding basin is formed with a liquid outlet, and an exchange element arranged in the exchange region. An upper part of the exchange element is disposed through the opening of the reservoir such that the upper part of the exchange element is arranged at least partially inside the reservoir and such that the upper part of the exchange element is at least partially submerged in the liquid.
