摘要： It is an object of the invention to provide an inexpensive double-pipe heat exchanger having high performance and comprising an inner pipe and an outer pipe which constitute a double pipe without adding a heat-transfer facilitating material such as an inner fin. In the double-pipe heat exchanger having the inner pipe and the outer pipe, the outer pipe is dented from its outside toward its inside, thereby forming a plurality of projections which tail down toward the inner pipe. Examples of shapes of the projection are substantially conical shape, substantially truncated shape, substantially spherical surface shape, substantially cylindrical shape, substantially elliptic cylindrical shape and the like. The projections are disposed helically or in a zigzag manner such as to surround the inner pipe. With this structure, only by subjecting the outer pipe to simple working such as press working, it is possible to increase the turbulent flow of fluid flowing between the inner pipe and the outer pipe, and to facilitate heat transfer from fluid flowing in the inner pipe to fluid flowing between the inner pipe and the outer pipe.

摘要： This invention relates to a ventilation system which assures a superior safety by suppressing a localized stagnation of a flammable gas and a concentration increase thereof in case a leakage of a flammable gas or refrigerant is detected. The ventilation system is comprised of a detector which detects a flammable gas or refrigerant, a ventilating fan which ventilates a room, a ceiling fan and an air conditioner indoor unit which stir the air of the room, en electric power supply switch which turns off a power supply to a fan heater or an electric stove. With this configuration, in the room, a localized stagnation of the gas can be avoided and a source of fire can be eliminated; thereby, a superior safety can be realized.

摘要： In the case of gas injection, a discharging temperature is not reduced sufficiently, and if an amount of injection is increased, a liquid refrigerant flows into a cylinder and the liquid is compressed, and the reliability can not be ensured. A refrigerator wherein at least a compressor, a radiator, a first throttle apparatus and an evaporator are connected to one another in an annular form to constitute a main circuit of a refrigeration cycle, a refrigerant which can be brought into a supercritical state by the radiator during operation is charged into the refrigeration cycle, the refrigerator comprises an injection pipe for injecting the refrigerant on the side of an outlet of the radiator into a cylinder of the compressor.
