摘要： PROBLEM TO BE SOLVED: To provide a heat exchanger, and a manufacturing method therefor, in which a molten brazing material does not leak to the joint of a header pipe and a heat exchanging pipe and thereby a refrigerant channel is not choked. SOLUTION: A heat exchanger comprises heat exchanging tubes 2, fins being fixed between the heat exchanging tubes 2, and a header pipe having tube insertion holes wherein the end part of the heat exchanging tube is inserted into the tube insertion hole and brazed thereto. The heat exchanging tube 2 is subjected to brazing material repellent processing for preventing a molten brazing material from adhering to the cross-section at the end part of the heat exchanging tube 2. A brazing material repellent layer 2b is formed on the cross- section at the end part of the heat exchanging tube and an abutting part 2c, from where the brazing material repellent layer 2b is removed, is formed the abutting part of a header pipe of the tube insertion hole.

摘要： PROBLEM TO BE SOLVED: To prevent the damage or breakage of a case in maintenance by arranging an elastic resin material between the case bottom surface and the roof panel of a vehicle in a device set on the roof panel of the vehicle and containing a refrigerating apparatus within the case. SOLUTION: This device is formed of a unit case (case) 7 and various air conditioning apparatuses provided therein. The case 7 is fixed to a roof panel 6 by metal fixtures 36a, 36b, and an elastic resin material 37 is interposed in about the lateral center of the vehicle between the bottom surface 7a of the case 7 and the roof panel. A worker gets on the inside of the case 7 to perform the inspection or replacement of various air conditioning apparatuses and electric parts. Therefore, as the elastic resin material 37, a hard resin material 37a is arranged on the bottom surface of the case 7, and a soft resin material 37b is provided on the roof panel 6. According to this, a local load is reduced to prevent the damage of the case 7, and the damage of the roof panel 6 is effectively reduced.

摘要： PROBLEM TO BE SOLVED: To start a sensor-less DC brushless motor completely in a short time by stopping signal supply after synchronous operation for a prescribed time, and restarting the motor if the speed of a rotor does not reach its prescribed value in switching to sensor-less operation with a position detection signal. SOLUTION: A compressor where a part of refrigerant liquefies and stays in a refrigerant flow passage when a room air conditioner is under a low ambient temperature is started for exhausting retained refrigerant. After respective driving windings 11 to 13 are energized for a prescribed energizing the with an accelerating control signal of prescribed motor application voltage to start a motor 10, the supply of the accelerating control signal is stopped. A speed determination means 41 determines if a rotor 14 has reached a prescribed rotational speed shifted to preset sensor-less operation. If so, a position detecting means 42 detects the rotational position of the rotor from an inductive voltage signal to output a sensor-less signal to the position feedback driving signal generating part 51 of a control circuit 50. The sensor-less signal outputs a commutating control signal to a drive 20 for sensor-less operation of the motor 10.

摘要： PROBLEM TO BE SOLVED: To provide optimum cycle efficiency, in a refrigerating cycle using supercritical fluid as a refrigerant and provided with a compressor, a radiator, an expansion device, an evaporator, and an internal heat-exchanger, and varying a delivery amount of the compressor. SOLUTION: In this refrigerating cycle, an operation condition containing a delivery amount of a compressor is regulated. In a refrigerant temperature and a refrigerant pressure on the inflow side of an expansion device, compared with a refrigerating cycle having no internal heat-exchanger and a refrigerating cycle where delivery capacity of the compressor is fixed, when a refrigerant temperature is the same, a refrigerant pressure is set to a higher value and when the refrigerant pressure is the same, a refrigerant temperature is set to a lower value. In more concrete, provided a refrigerant temperature on the inflow side of an expansion device is T [ deg.C] and a refrigerant pressure on the inflow side of the expansion device is P [MPa], T and P are set to a range surrounded by T =2.52P-7.41.
