Abstract
A test chamber and a method for conditioning air in which the test chamber comprises a temperature-insulated test space, which is closable to an environment and serves to receive test material, and a temperature control device for controlling the test space in temperature, a temperature ranging from −40° C. to +180° C. being generable within the test space by the temperature control device. The temperature control device comprises a cooling apparatus having a first and second cooling cycle, the first cooling cycle having a first refrigerant, a first heat exchanger, a first compressor, a first condenser and a first expansion element, the first refrigerant being a hydrocarbon or a refrigerant mixture made of hydrocarbons. The second cooling cycle has a heat transfer medium, a second heat exchanger in the test space and a pump, the second cooling cycle being coupled to the first cooling cycle by the first heat exchanger.
