Abstract
A temperature chamber for conditioning air includes a temperature-insulated space which receives test material, and a temperature control device for controlling the temperature of the test space. The temperature control device allows a temperature in a range of −50° C. to +180° C. to be established within the space, and has a cooling device including a cooling circuit with a refrigerant, a heat exchanger, a compressor, a condenser, and an expansion element. A jet device is connected to a low-pressure side of the cooling circuit downstream of the heat exchanger and upstream of the compressor, a first bypass is connected to a high-pressure side of the cooling circuit downstream of the compressor, and the refrigerant is suppliable to the jet device from the high-pressure side via the first bypass as a driving fluid.
