摘要： PURPOSE:To restrict an amount of discharged oil within a compressor to a minimum value during heating operation by a method wherein the first cylinder disposed below the compressor is connected to an outdoor heat exchanger and the second cylinder disposed above the compressor is connected to a refrigerant heating side. CONSTITUTION:Refrigerant at a suction side of the second cylinder 35 at a refrigerant heating side has a low specific volume due to the fact that its pressure is higher as compared with that of refrigerant in the first cylinder 33. In the case of the cylinders having the same capacity to each other, the second cylinder 35 had remarkably higher flow rate than that of the first cylinder 33 at the same member of rotation. Although lubricant oil within the compressor 25 is apt to be easily accumulated at the lower first cylinder 33 due to its own weight, the first cylinder 33 has a quite low flow rate of refrigerant as compared with that of the second cylinder 35 and then a discharging amount of oil accumulated there is restricted to a minimum value. Accordingly, lubrication of each of the portions within the compressor 25 is superior and the compressor 25 is stably operated.

摘要： PURPOSE:To supply balanced combustion air to two burners by matching the center of the vane wheel of a centrifugal fan in the direction of its width to the center of two burners that are in parallel. CONSTITUTION:A wind box 1 is constituted, for instance, of a box body which is elliptically shaped with its cross section on a plane being longitudinally long, and at its upper wall section two openings 1a and 1a in parallel are provided which are circular and are at positions symmetrical to the right and to the left with respect to the center of the longitudinal direction of the wind box 1. In the inside of the wind box 1 which has the ports 1a and 1a cylindrical burners 2a and 2a are set upright and in parallel. At the circumferential wall section on the one side of the burner outer cylinder 3 in the direction of the transverse direction of the wind box 1 an air intake opening 4 is provided. On the other side of the circumferential wall which is opposite to the opening 4 and is in the transverse direction of the wind box 1 a centrifugal fan 15 is installed for supplying air required for combustion. The centrifugal fan 15 is parallel to the line alpha connecting the axis X1 and axis X2 of the burners 2a and 2b and the axis beta of the vane wheel 17, and the fan 15 is placed so as to make the center in the direction of the width of the vane wheel 17 the center of the line alpha, and the blast air blown out from the blow-out section can be sent equally to the sides of both burners 2a and 2b.

摘要： PURPOSE:To make larger the heat transfer area of the tail pipe section and realize a compact overall construction by constituting the combustion cylinder and tail pipe with an incorporated pipe with the same cross-sectional shape, and installing in the tail pipe section of the incorporated pipe an inner pipe which reduces the heat transfer area at the tail pipe section. CONSTITUTION:A combustion chamber 32 and a tail pipe passage section 33 are constituted in a pipe 31 which is incorporated in the chamber and passage section of an inner pipe 34 concentrically provided in the pipe 31 and with a diameter smaller than that of the pipe 31 and which has its both ends closed. Accordingly the incorporated pipe 31 functions as a combustion cylinder at its section constituting the combustion chamber 32 and functions as a tail pipe at the section constituting the tail pipe passage section 33. The cross-sectional area of passage of the tail pipe passage section 33 becomes smaller than the cross-sectional passage area of the combustion chamber 32 because of the existence of the inner cylinder 34. Since the combustion cylinder and the tail pipe are thus formed merely by the cylindrical incorporated pipe 31, only one extrusion die is enough when, for instance, the burner wall is manufactured with a member made of aluminium extrusion so that cost reduction can be expected. Further, it is possible to enlarge the heat transfer area on the side of the combustion gas of the tail pipe section and at the same time it is possible to raise the heat transfer coefficient because of the radiation heat transfer from the inner pipe 34.

摘要： PURPOSE:To provide a stable ignition as well as a silent ignition in a double pulse combustion device for a heating operation by a method wherein a pair of pulse burner exhausting pipes are in common with a combustion air supply pipe and a coefficient in forward direction of an air flow rate control valve is set higher than that of a reverse direction and each of igniting means is alternatively ignited. CONSTITUTION:A combustion air supply fan 17 is driven to supply combustion air to combustion chambers 10a and 10b through an air supply decoupler 16 and at the same time fuel is supplied from fuel supply pipes 13a and 13b, respectively. With such an arrangement, mixture gas which can be ignited instantaneously is generated within both combustion chambers 10a and 10b. Igniters 14a and 14b are alternatively energized by the controlling means 20 and a combustion is started from either one of them. In subsequent, the other combustion chamber starts to ignite and during this period, a combustion air and fuel for a next operation are supplied to a previous ignited combustion chamber. With such an arrangement, it is possible to perform a silent and stable ignition.

摘要： PURPOSE:To attain stable combustion at all times by providing a pressure control means whereby a difference between the upstream-side pressure of a flow control valve and the pressure of a combustion chamber is maintained at a prescribed value or above from the time point of the start of ignition. CONSTITUTION:When a start instruction is given, a fan control device 20 makes an air supply fan 19 rotate at a low speed and controls an igniter drive circuit 21 to make igniters 14a and 14b start operations, while making a fuel supply valve 34 open. A fuel is jetted into combustion chambers 10a and 10b through fuel injection ports and ignition is executed. When the fan control device 20 detects by flame sensors 15a and 15b that a mixed gas burns, it makes the air supply fan 19 rotate at a high speed, so as to supply a large amount of the air to the combustion chambers 10a and 10b through an air supply decoupler 18, flow control valves 17a and 17b. With the air in a larger amount than that before the start of combustion supplied, stable pulse combustion is conducted in the combustion chambers 10a and 10b.

摘要： PURPOSE:To transit the combustion smoothly to the state of inverse phase combustion by performing the independent action of pulse combustion when a pulse burner of connecting type is ignited and enhancing the interference gradually after the ignition. CONSTITUTION:A pair of pulse burners 16a and 16b are formed in the same shape and they are connected by a supply air decoupler 12. At an intermediate positions in air supply pipes 30a and 30b flow rate control valves 32a and 32b are provided which have a larger flow rate coefficient in positive direction than the flow rate coefficient in negative direction. In the supply air decoupler 12 a divided valve 50 is installed which is rotatable with the axial center line 52 as the center. When igniting each pulse burner starts operation independently with the inside of the supply air decoupler 12 divided by a divided valve 50. Afterwards, the state of division of the divided valve 50 is gradually released and the interface of both pulse burners is enhanced. In the state of constant combustion the divided valve 50 is fully open and both pulse burners perform combustion actions which are perfectly in the reverse phase.

摘要： PURPOSE:To efficiently realize the reduction of temperature of combustion gas by composing a burner of a pulse combustion type burner body having a combustion chamber connected at its downstream end to a tail tube, and a water supply tube so provided as to communicate with the tail tube near the chamber. CONSTITUTION:Since an abrupt combustion occurs in a combustion chamber 11 at the time of explosion combustion, the interior in the chamber 1 becomes positive pressure in comparison with the atmospheric pressure. Thus, combustion gas flows out of the chamber 11, but since a unidirectional valve 16 is disposed at its upstream side, most combustion gas flows to a discharge decoupler through a tail tube 12 as designated by an arrow 31. In this case, water in a water supply tube 23 communicating with the tube 12 is atomized at 32 into the tube 23 by an ejector effect similarly to an atomizer, and invaded into the combustion gas to be evaporated. Accordingly, the gas is reduced at its temperature due to the removal of its heat by means of sensible heat of the water and evaporating latent heat.

摘要： PURPOSE:To make it possible to confirm easily either excess cooling state or irradiated state and hence prevent the generation of troubles during housing, by releasing excess cooling state of latent heat regeneration materials by a manual release switch, performing action display during phase change after the excess cooling state is released. CONSTITUTION:When starting the heating, the indoor air sucked up from an indoor air suction port 13 by an air circulation fan 12, is brought into a state where the sucked up indoor air is capable of heat exchanging with the heat accumulated in a regeneration tank 3. The air is rapidly heated by the latent heat generated by operating an excess cooling release means 6 and advancing the change in phase of a latent heat regeneration material 4, and the hot air thus produced is immediately introduced indoors from a louver 14 until a heat exchanger 9 comes to a set temperature. The latent heat regeneration material 4 is heated and accumulated by the hot air transferred by a fan 12 during steady combustion after a temperature detection means 15 operates when the heat exchanger 9 reaches the set temperature. During off-season, an excess cooling operation is manually released by manipulating a manual release switch 20 under the excess cooling state of the latent heat regeneration material 4 and a hot air heater is housed. During the release of excess cooling state, a pilot lamp 21 is lit up. When the latent regeneration material 4 finishes its radiation, the pilot lamp 21 is put out, which makes it possible to confirm easily whether it is under the release of excess cooling or not.

摘要： PURPOSE:To reduce the size while to improve the heatexchange efficiency by providing a pulse combustor in the combustor of a Stirling engine while arranging a high temperature heatexchanger at the tail tube section. CONSTITUTION:A combustion chamber 25 is arranged above a Stirling engine body 1. Combustion air is fed through a flapper valve 30 while fuel is fed through a flapper valve 29 into the combustion chamber to ignite the mixture gas by means of an ignition plug 26. Upon pressure rise in the combustion chamber 25 because of the combustion pressure, respective flapper valves 29, 30 will close to interrupt supply of the fuel and the air where the high temperature combustion gas is discharged to the tail tube section 32 of the pulse combustor and heatexchanged through a high temperature heatexchanger 22 arranged at the tail tube section 32 to heat the operating gas then an air preheat tube 32 and exhausted. Here, the interior of the combustion chamber 25 is brought into negative pressure because of the inertia of exhaust gas to open respective flapper valves 29, 30 thus to form mixture gas in the combustion chamber 25 and ignite with the temperature in the combustion chamber to perform pulse combustion.
