Abstract

"APARELHO DE REFRIGERAçãO". é provido um aparelho de refrigeração que compreende, pelo menos, dois compartimentos de armazenamento (10, 1 1) e um circuito refrigerante que compreende um compressor (14), um condensador (15), mecanismos de válvula (18, 19) e dois evaporadores (12, 13). O compressor (14) é um compressor de capacidade variável, e os ditos mecanismos de válvula são constituídos por uma válvula unidirecional (18) e uma válvula de direção de fluxo (19) para alimentar seletivamente os ditos evaporadores via os respectivos mecanismos de estrangulamento (16, 17). O resultado é um sensível efeito de economia de energia na operação do aparelho."COOLING EQUIPMENT". a refrigeration apparatus is provided comprising at least two storage compartments (10, 11) and a refrigerant circuit comprising a compressor (14), a condenser (15), valve mechanisms (18, 19) and two evaporators (12, 13). The compressor (14) is a variable capacity compressor, and said valve mechanisms are comprised of a one-way valve (18) and a flow direction valve (19) for selectively feeding said evaporators via the respective throttling mechanisms ( 16, 17). The result is a significant energy saving effect on the operation of the device.
