Abstract

TROCADOR DE CALOR DE CANO DUPLO E AR CONDICIONADO USANDO O MESMO. Trocador de calor de cano duplo capaz de realizar configuração compacta e suprimir refrigerante líquido contido em refrigerante de duas fases de gás-líquido de fluir para fora de cano interno, para evitar a geração de um fenômeno de retorno de líquido. Trocador de calor de cano duplo (31) inclui cano externo (32) pelo qual refrigerante líquido de pressão alta flui, e cano interno (33) tendo extremidade lateral de entrada (33A), no qual refrigerante de pressão alta de duas fases de gás-líquido, obtido reduzindo pressão do refrigerante líquido de pressão alta, flui, uma extremidade no lado da saída (33B) conectada à parte lateral de sucção do compressor. O trocador de calor de cano duplo (31) inclui uma pluralidade de canos verticais (34A, 34B) dispostos nas direções para cima e para baixo, e cano curvo (35) conectando extremidades da pluralidade de canos verticais (34A, 34B), a extremidade do lado da saída (33B) do cano interno (33) é fornecida em uma extremidade superior de cano vertical (34B), extremidade lateral de entrada (33A) do cano interno (33) é fornecida em uma extremidade superior do outro cano vertical (34A).DOUBLE BARREL HEAT EXCHANGER AND AIR CONDITIONER USING THE SAME. Double-barrel heat exchanger able to realize compact configuration and suppress liquid refrigerant contained in two-phase gas-liquid refrigerant from flowing out of inner pipe, to avoid generating liquid back phenomenon. Double-barrel heat exchanger (31) includes outer pipe (32) through which high pressure liquid refrigerant flows, and inner pipe (33) having inlet side end (33A), in which two-phase gas high pressure refrigerant -liquid, obtained by reducing pressure of the high pressure liquid refrigerant, flows, one end on the outlet side (33B) connected to the suction side of the compressor. The double-barrel heat exchanger (31) includes a plurality of vertical pipes (34A, 34B) arranged in upward and downward directions, and curved pipe (35) connecting ends of the plurality of vertical pipes (34A, 34B), the the outlet side end (33B) of the inner barrel (33) is provided at an upper end of the standpipe (34B), the inlet side end (33A) of the inner barrel (33) is provided at an upper end of the other standpipe (34A).
