\n\tA pot\u00eancia de refrigera\u00e7\u00e3o do circulador de refrigera\u00e7\u00e3o de baixa temperatura varia consoante as diferentes condi\u00e7\u00f5es de trabalho. Assim, quando o c\u00e1lculo do processo \u00e9 efectuado no in\u00edcio, \u00e9 necess\u00e1rio definir uma margem para a pot\u00eancia de refrigera\u00e7\u00e3o do circulador de... circulador de aquecimento e arrefecimento<\/a> para evitar que a pot\u00eancia de refrigera\u00e7\u00e3o n\u00e3o seja suficiente.\n<\/p>\n

\n\tA pot\u00eancia de refrigera\u00e7\u00e3o do circulador de refrigera\u00e7\u00e3o de baixa temperatura est\u00e1 intimamente relacionada com o compressor, o evaporador, o condensador e a v\u00e1lvula de expans\u00e3o. A pot\u00eancia de refrigera\u00e7\u00e3o do compressor est\u00e1 relacionada com a temperatura de evapora\u00e7\u00e3o e a temperatura de condensa\u00e7\u00e3o, que diminui com a diminui\u00e7\u00e3o da temperatura de evapora\u00e7\u00e3o ou com o aumento da temperatura de condensa\u00e7\u00e3o. A pot\u00eancia de refrigera\u00e7\u00e3o do evaporador \u00e9 determinada n\u00e3o s\u00f3 pelo valor da diferen\u00e7a entre a temperatura do reservat\u00f3rio e a temperatura de evapora\u00e7\u00e3o, mas tamb\u00e9m pelo grau de sobreaquecimento \u00e0 sa\u00edda do refrigerante (seco) ou pelo n\u00edvel de l\u00edquido (l\u00edquido cheio). Quando a temperatura do reservat\u00f3rio \u00e9 constante, a pot\u00eancia de refrigera\u00e7\u00e3o do evaporador aumenta com a diminui\u00e7\u00e3o da temperatura de evapora\u00e7\u00e3o. A pot\u00eancia de refrigera\u00e7\u00e3o do condensador pode ser calculada a partir da curva de refrigera\u00e7\u00e3o do condensador. Quando o rendimento da \u00e1gua de arrefecimento ou a temperatura de condensa\u00e7\u00e3o baixam, a pot\u00eancia de refrigera\u00e7\u00e3o diminui. Al\u00e9m disso, quando o rendimento da \u00e1gua de arrefecimento diminui e a temperatura da \u00e1gua de arrefecimento aumenta, a pot\u00eancia de refrigera\u00e7\u00e3o tamb\u00e9m diminui. O d\u00e9bito de refrigera\u00e7\u00e3o da v\u00e1lvula de expans\u00e3o est\u00e1 relacionado com a diferen\u00e7a de press\u00e3o entre a entrada e a sa\u00edda da v\u00e1lvula e o refrigerante neste estado de funcionamento. Assim, quando a temperatura de condensa\u00e7\u00e3o desce, a pot\u00eancia de refrigera\u00e7\u00e3o diminui, e a pot\u00eancia de refrigera\u00e7\u00e3o diminui quando a press\u00e3o de evapora\u00e7\u00e3o \u00e9 demasiado alta ou demasiado baixa.\n<\/p>\n

\n\tA partir daqui, pode ver-se que a pot\u00eancia de refrigera\u00e7\u00e3o do circulador de refrigera\u00e7\u00e3o de baixa temperatura est\u00e1 relacionada com a carga t\u00e9rmica, a \u00e1rea de evapora\u00e7\u00e3o, a \u00e1rea de transfer\u00eancia de calor e a \u00e1rea do compressor. As altera\u00e7\u00f5es em qualquer um dos factores afectar\u00e3o a pot\u00eancia de refrigera\u00e7\u00e3o.\n<\/p>\n

\n\tA \u00e1rea de transfer\u00eancia de calor do circulador de arrefecimento a baixa temperatura refere-se principalmente \u00e0 \u00e1rea de evapora\u00e7\u00e3o do evaporador, e a altera\u00e7\u00e3o da \u00e1rea de transfer\u00eancia de calor refere-se principalmente \u00e0 altera\u00e7\u00e3o da \u00e1rea de evapora\u00e7\u00e3o. O efeito do aumento e diminui\u00e7\u00e3o da \u00e1rea de evapora\u00e7\u00e3o na temperatura de evapora\u00e7\u00e3o \u00e9 basicamente semelhante ao aumento e diminui\u00e7\u00e3o da carga de calor na temperatura de evapora\u00e7\u00e3o. Quando a \u00e1rea de evapora\u00e7\u00e3o aumenta, a temperatura de evapora\u00e7\u00e3o aumenta; quando a \u00e1rea de evapora\u00e7\u00e3o diminui, a temperatura de evapora\u00e7\u00e3o diminui. Quando a carga t\u00e9rmica do circulador de arrefecimento a baixa temperatura aumenta e as outras condi\u00e7\u00f5es s\u00e3o constantes, a temperatura de evapora\u00e7\u00e3o aumenta, a press\u00e3o da baixa press\u00e3o aumenta e o grau de sobreaquecimento da suc\u00e7\u00e3o aumenta. Quando a energia do compressor de refrigera\u00e7\u00e3o \u00e9 aumentada, o volume de suc\u00e7\u00e3o do compressor aumenta correspondentemente, sob a condi\u00e7\u00e3o de que outras coisas sejam iguais, a alta press\u00e3o aumentar\u00e1, a baixa press\u00e3o diminuir\u00e1 e a temperatura de evapora\u00e7\u00e3o diminuir\u00e1. O ajuste da press\u00e3o de evapora\u00e7\u00e3o do circulador de refrigera\u00e7\u00e3o de baixa temperatura pode ser realizado alterando o grau de abertura da v\u00e1lvula de estrangulamento ou ajustando o caudal de g\u00e1s do compressor de refrigera\u00e7\u00e3o. Se a v\u00e1lvula de estrangulamento for baixada, a circula\u00e7\u00e3o do refrigerante \u00e9 reduzida, a evapora\u00e7\u00e3o no evaporador \u00e9 reduzida em conformidade e a press\u00e3o de evapora\u00e7\u00e3o \u00e9 reduzida em conformidade. Inversamente, se a v\u00e1lvula for aumentada, a press\u00e3o de evapora\u00e7\u00e3o aumentar\u00e1 de forma correspondente.\n<\/p>\n

\n\tPor conseguinte, o ajuste da sa\u00edda de refrigera\u00e7\u00e3o do circulador de refrigera\u00e7\u00e3o de baixa temperatura pode ser feito de forma flex\u00edvel, ou seja, todos alinhados uns com os outros, \u00e9 necess\u00e1rio prestar mais aten\u00e7\u00e3o \u00e0 opera\u00e7\u00e3o.<\/p>","protected":false},"excerpt":{"rendered":"
