Abstract: The refrigeration cycle device has a refrigerant circuit, a liquid receiver, a reaction casing, a cool radiation evaporator and a cool storage/radiation controller. The liquid receiver is disposed in the refrigerant circuit for accumulating liquid refrigerant. The reaction casing is connected to the liquid receiver. The reaction casing selectively serves as a release device for releasing refrigerant gas and as a recovery device for recovering the refrigerant gas. The cool radiation evaporator is disposed in a refrigerant passage between the liquid receiver and the reaction casing when the reaction casing serves as the recovery device. The cool radiation evaporator heats the liquid refrigerant sent from the liquid receiver. The cool storage/radiation controller controls the reaction casing to serve as one of the release device for performing cool storage and the recovery device for performing cool radiation.

Abstract: The invention features apparatuses and methods for inactivating viruses, bacteria, and other pathogens in protein-containing fluids. The apparatuses include a radiation transparent housing at least of a portion of which is radiation transparent. In addition, the housing contains a static mixer such that fluid flowing the housing approximates fully mixed flow. Pathogens are inactivated in liquids flowing through an apparatus of the invention by exposing the liquid to UV radiation, e.g., UVC radiation, at an appropriate intensity for an appropriate period of time.
