Vapor-phase heat-transport systems are being tested in two of the passive test cells at Los Alamos. The systems consist of an active fin-and-tube collector and a condenser inside a water storage tank. The refrigerant, R-11, can be returned to the collector with a pump or with a self-pumping scheme. A computer model was developed to predict the behavior of the system, after which the computer was used to predict the annual performance of these systems in five cities. The report compares the measured and the predicted results as well as the system's sensitivity to several parameters.
