Abstract

MéTODO PARA CONTROLAR A CARGA DE REFRIGERANTE EM UMA BOMBA DE CALOR REVERSìVEL. Um sistema de bomba de calor inclui um compressor, uma válvula reversível, um trocador de calor externo e um trocador de calor interno em um circuito, e um trocador de calor de refrigerante para água. No modo de resfriamento do ar com aquecimento de água, o modo de aquecimento de ar com aquecimento de água e o modo somente de aquecimento de água, água, de um reservatório de água é passada através do trocador de calor de refrigerante para água. Um reservatório de refrigerante deve ser provido para uso no controlador de carga de refrigerante. Uma linha de refrigerante (71) acopla o reservatório ao circuito de refrigerante intermediando os trocadores de calor externo e interno para direcionar refrigerante líquido para o reservatório e uma linha de refrigerante (73) acopla o circuito refrigerante corrente acima da entrada de sucção do compressor para retornar refrigerante para o circuito refrigerante. Um controlador controla o fluxo para dentro e para fora do reservatório de refrigerante através de abertura e fechamento seletivo da válvula de controle (72) na linha (71) e válvula de controle (74) na linha (73).
