Abstract

"VáLVULA TERMOSTáTICA DE EXPANSãO DE REFRIGERANTE ELETRICAMENTE CONTROLADA E MéTODO PARA CONTROLAR REFRIGERANTE EM UM SISTEMA DE RESFRIAMENTO RECIRCULANTE DE LAçO FECHADO". Sistema refrigerante tendo válvulas de expansão térmicas inividuais para controlar fluxo de refrigerante a partir de um compressor e um condensador comuns para evaporadores separados remotamente localizados tais como para conforto de passageiros dos assentos dianteiros e traseiros de veículo. Uma das válvulas de expansão térmica remota tem um resfriador termo elétrico em relacionamento condutor de calor com a cápsula de energia cheia de fluido da válvula. Com a energização do resfriador termoelétrico a temperatura detectada do refrigerante retornando através da válvula a partir do evaporador para o compressor é alterada para fazer a válvula reduzir o fluxo de refrigerante para o evaporador para compensar pelo suprimento de refrigerante reduzido devido ao fluxo através da outra válvula de expansão térmica.
