A NEW TOPOLOGY FOR VPRS AIR CONDITIONING SYSTEM USING HEAT EXCHANGER MODULES THAT INCORPORATE MICROCHANNELS

摘要

This application is an implementation of using modules or other module configurations as suggested on IPOPHL patent on micro channel topology with the mirochannels fabricated in a more compact manner such that other two phase materials may easily be used with the resulting module. The modules incorporates the suggested topology in IPOPHL patent application 1201400025. This application speicifies in detail an obvious extension of the patent application where the idea is incorporated into a module consisting of a large metal assembly with thousands of the microchannels etched and assembled by sinter diffusion welding. The module results in a compact unit and together with the application on the module of a two fluid material two phase process (refrigernat and water ) with the latter incorporating vaporization as suggested in the 20110292172 USPTO patent application. The resulting COP is very low and incorporating again the microchannels into the block module allows us to get rid of the bulky compressor and create a diffuser augmented by electric heater to provide the phase changes for the condenser from the evaporator.
