Abstract: A refrigeration plant (100) for cooling a target fluid to a target temperature between ?80° C. and +30° C. by means of ambient air, having a compressor refrigerant system (105) having a compressor (125) and a target heat exchanger (120) for cooling the target fluid; a natural circulation refrigerant system (140) having an ambient air condenser (145) and a control valve (165), and an intermediate heat exchanger (120) which couples the natural circulation refrigerant system (140) to the compressor refrigerant system (105).

Abstract: Device for the extracorporeal controlling of the temperature of patients by transmitting heat between a fluid and a transmission medium, having a primary circuit having a primary unit (102, 201) for receiving the fluid, and a secondary circuit having a secondary unit (104, 200) which includes connectors (240, 242) for infeeding and outfeeding the transmission medium, wherein the secondary unit (104, 200) is capable of being fastened to the primary unit (102, 201) and has nozzles (206) for configuring an impingement flow, said nozzles (206), in the case of a secondary unit (104, 200) being fastened to the primary unit (102, 201), being directed in the direction of the primary unit (102, 201).

Abstract: Device (100, 201) for the adjustment of temperature, especially for the extracorporeal adjustment of the temperature of patients, with a transfer of heat between a fluid and a transfer medium, including a temperature-adjustment body (203) having a primary side which provides a guide for the fluid and having an application side which provides a surface (219) for contacting the temperature-adjustment body (203) with the transfer medium; a cover (221) which is attached to the temperature-adjustment body (203) and which forms a cavity with the temperature-adjustment body (203) on the application side, through which cavity the transfer medium can flow; the cover (221) being attached to the temperature-adjustment body (203) in a detachable manner; and flow-guiding structures (217) for guiding the transfer medium being arranged on the temperature-adjustment body (203) and/or on the cover (221).
