Abstract

Patente de Invenção: <B>"COMPRESSORES ALTERNADOS DE DUPLO ESTáGIO E SISTEMAS E PROCESSOS HVAC ASSOCIADOS"<D>. São descritos um compressor alternado de duplo estágio e sistemas e processos HVAC associados. O compressor alternado inclui um eixo de manivela que possui um virabrequim excêntrico, um motor reversível para girar o eixo de manivela em uma direção avante e uma direção contrária, e um came excêntrico de duas posições giravelmente montado sobre o virabrequim. O eixo de manivela e o came são combinados para fazerem com que o pistão tenha um primeiro curso, quando o motor operar na direção avante, e um segundo curso, quando o motor operar na direção contrária. O came e o virabrequim também incluem um meio de estabilização para limitar a relativa rotação do came em torno do virabrequim. Um sistema de lubrificação provido para lubrificar as superfícies de engate do eixo de manivela e do came e entre o came e a superfície do mancal da biela. também é provido um controle para seletivamente operar o motor, quer seja na direção avante em uma primeira carga de potência, quer seja na direção contrária em uma segunda carga de potência reduzida. Também é provido um protetor para o motor. Além disso, é descrita a aplicação do compressor alternado, tanto para o sistema de condicionamento de ar, como para o sistema de bomba de calor.
