Abstract
"MéTODO E ARRANJO PARA DEGELO DE UM TROCADOR DE CALOR (EVAPORADOR) EM UM SISTEMA DE COMPRESSãO DE VAPOR". Método para degelo de um trocador de calor (evaporador) em um sistema de compressão de vapor incluindo, além de um trocador de calor (evaporador) (3) a ser degelado, pelo menos um compressor (1), um segundo trocador de calor (condensador/rejeitador de calor) (2) e um dispositivo de expansão (6) conectado por condutos de uma maneira operável para formar um circuito fechado integral. O trocador de calor (3) a ser degelado é sujeito essencialmente à mesma pressão como a pressão de descarga do compressor (1), por meio de que o trocador de calor (3) é degelado quando o gás de descarga de alta pressão do compressor (1) flui pelo trocador de calor, passando calor ao dito trocador de calor (3). Um arranjo é caracterizado pelo fato de que, no circuito, com relação ao dispositivo de expansão (6), é provido um primeiro laço de desvio (23) com uma primeira válvula (16'), e que um dispositivo redutor de pressão (6') é provido em um segundo laço de desvio junto com uma segunda válvula (1 6"') disposta depois do trocador de calor (3) sendo degelado, por meio de que a primeira válvula (16') é aberta e a segunda válvula (16"') é fechada quando degelo acontece.
