Abstract

"PROCESSO E SISTEMA PARA CONTROLAR UM CICLO DEDESCONGELAMENTO DE SERPENTINA EM UM SISTEMA DEBOMBA DE AQUECIMENTO REVERSìVEL UTILIZANDO UMCICLO REFRIGERANTE". Um algoritmo de controle controla umciclo de descongelamento de serpentina em uma bomba deaquecimento reversível pelo armazenamento de valores querepresentam o desempenho de uma serpentina limpa, isso é, umasem qualquer acúmulo de gelo, e o monitoramento desses valoresà medida em que se desenvolvem com o tempo. Os valores sãoutilizados para criar um "fator de congelamento" cujo valor variaentre 0%, significando uma serpentina limpa, e 100%, significandouma serpentina altamente congelada. Quando o fator decongelamento atinge um valor predeterminado perto de 100%, ociclo refrigerante da bomba de aquecimento é invertido para sealcançar o descongelamento da serpentina.
