Abstract

"SISTEMA DE RESFRIAMENTO A CO~ 2~". Um sistema de resfriamento (10) que inclui um evaporador (28), uma linha de sucção (74), um compressor de dois estágios (20), um resfriador de gás (24) e um tubo capilar (60). A linha de sucção recebe refrigerante gasoso ou bifásico do evaporador, o compressor recebe o refrigerante gasoso ou bifásico da linha de sucção, e o resfriador de gás resfria o refrigerante comprimido descarregado do compressor. O tubo capilar porta refrigerante do resfriador de gás para o evaporador, e a linha de sucção pode incluir duas porções retas com duas porções do tubo capilar enroladas de forma helicoidal em torno dali, com uma válvula de by-pass (24) em torno do tubo capilar, e um acumulador entre as porções de linha de sucção. Um resfriador intermediário (38) está entre os estágios do compressor e uma panela coleta condensado de água a partir do lado de ar do evaporador, e o tubo de refrigerante porta refrigerante resfriado do resfriador de gás através da panela. Um controlador (92) seletivamente liga e desliga o compressor com base na temperatura ou na pressão detectada por um sensor (94).
