Integrated continuous power system assemblies

This invention relates to continuous power systems. In particular, the present invention relates to continuous power systems that utilize a source of stored thermal energy to provide a continuous supply of electric power when a primary power supply fails, or when deterioration occurs in the power being supplied to the end user. A continuous power system accumulator assembly is provided that stores thermal energy as sensible heat and minimizes the amount of thermal energy wasted by the system. The assembly includes an accumulator at its core. A preheater assembly is wrapped around the accumulator such that it may absorb heat radiated and conducted from the accumulator. An evaporator is wrapped around the preheater so that most of the heat that is radiated and conducted from the preheater is utilized to heat the vaporizer. The outer housing of the assembly may be a double-walled housing having a layer of insulation located between the two walls. This configuration minimizes heat losses by the assembly.
