Abstract: The combination aeration, deaeration, and water outlet valve includes a common water inlet, gas inlet, and gas outlet for connecting to a climate chamber; a water reservoir connected to the common water inlet, gas inlet, and gas outlet; a first valve assembly with a first valve seat penetrated by a first passage and with a first closing element pressed onto the first valve seat by a first closing force such that it blocks the first passage until the first closing force is overcome; a second valve assembly with a second valve seat penetrated by a second passage and with a second closing element pressed by a second closing force onto the second valve seat such that it blocks the passage until the second closing force has been overcome; and a drainage opening for air and water disposed at a height of an upper edge of the second valve seat.

Abstract: Provided is a climate chamber with an outer casing, with an inner casing disposed within the outer casing, and with a vapor inlet which penetrates a rear wall of the outer casing, in which in front of the vapor inlet in the region between the rear wall of the outer casing and an inner casing rear wall a flow barrier is disposed.

Abstract: The application relates to a roll bond evaporator plate with a width and a height, wherein the roll bond evaporator plate comprises at least one cutout which is delimited at least on three side edges by the roll bond evaporator plate. The application further relates to a refrigerant circuit with such roll bond evaporator plate as well as to a laboratory chamber, climate chamber, cold chamber or environment simulation chamber with such roll bond evaporator plate.

Abstract: A Peltier module or device with at least one Peltier element with a first surface and an oppositely located second surface, wherein on the first surface a first heat transfer element of an air duct is disposed, wherein the air duct, for the conduction of air along the first heat transfer element, comprises an input opening, in which a ventilator is disposed, and an output opening and wherein on the second surface a second heat transfer element of a cooling body is disposed, wherein the ventilator is developed and disposed such that an air flow generated by the ventilator forms with the first surface an angle (?) between 10° and 80°, as well as a laboratory chamber, a refrigerator chamber, a cold chamber, a climate chamber or an environmental simulation chamber with at least one such Peltier module.

Abstract: An evaporator for a climate chamber, in particular for a constant climate chamber with temperature- and humidity control, comprising a first inlet, a second inlet and an outlet for a refrigerant, wherein the first inlet, the second inlet, and the outlet are connected with one another by a duct, and wherein the second inlet is disposed between the first inlet and the outlet, and a climate chamber with an evaporator.

Abstract: A method of operating a humidifying module for an incubator, the humidifying module having a container with a water inlet and a steam outlet, a heating device which is arranged in the interior of the container, and a temperature sensor and a control circuit for controlling or regulating a water supply through the water inlet and/or for controlling or regulating a heat output of the heating device, wherein container is filled with water, at a maximum, so that a steam volume remains, in which there is steam generated when heating with the heating device, wherein part of the heating device protrudes from the water and projects into the steam volume, so that the steam can be superheated, and wherein the temperature sensor is arranged to directly or indirectly measure the temperature of the steam, the measured temperature being used as a control parameter by the control circuit, a humidifying module for an incubator for carrying out such a method, and an incubator with such a humidifying module.
