    摘要： A refrigeration cycle that controls the deposit of foreign matter at inlet or outlet of a capillary tube, which forms an expansion device in the refrigeration, regardless of changeover from a cooling operation to a heating operation. In particular, in a refrigeration cycle using an alternative refrigerant, a junction is provided for joining an end of a capillary tube forming an expansion device to the piping through which the refrigerant flows. The junction has a slope defined by the inside diameter thereof, which gradually decreases from the side of the junction that joins the piping to the side of the junction that joined the capillary tube. An end portion of the capillary tube projects into the junction at the piping side. The projecting end of the capillary tube is opened obliquely to the axial line of the capillary tube. A hole is formed in the peripheral wall of the projecting end of the capillary tube. According to such an arrangement, foreign matter in the refrigerant is forced to be deposited in portions of the refrigerant cycle other than the capillary tube and prevented from clogging the capillary tube.

    摘要： A low-cost, high-mass-productivity catalytic combustion apparatus having a construction that permits easy maintenance is realized. There is provided a catalytic combustion apparatus in which, by means of a combustion chamber having a fuel supply portion 1 and a combustion air supply portion on the upstream side thereof and a combustion gas exhaust port on the downstream side thereof and a catalytic combustion portion with an upstream surface and a downstream surface provided in the combustion chamber, the upstream surface and the downstream surface being substantially parallel to each other, a fuel-air mixture supplied to the interior of the combustion chamber is caused to react to liberate heat. The catalytic combustion apparatus includes a heat exchange portion, which constitutes part of walls of the combustion chamber, and a fin-type radiant heat-receiving portion, which protrudes from the heat exchange portion into the combustion chamber and being provided in the vicinity of the catalytic combustion portion. In this catalytic combustion apparatus, the surface of the fin-type radiant heat-receiving portion and the surface of the heat exchange portion face in the same direction.
