摘要： PURPOSE:To prevent the rise of temperature inside an underground tunnel by installing a heat accumulation control means for selectively controlling the heat accumulation of the heat in a refrigeration cycle or the supply of heat into the refrigeration cycle according to the traveling place of a train or time. CONSTITUTION:A cooler on a subway train which is equipped with a self refrigeration cycle 14 which is constituted of a compressor 15, exterior heat exchanger 16, expansion valves 17a and 17b, and an interior heat exchanger 18, and a heat accumulator tank 19 having a heat exchanger 21 built in is assembled into the refrigeration cycle 14. In a train depot, at a return back station on the ground, or in the ground traveling division at night and in the early morning, each solenoid valve 20a-20i is opening/closing-controlled by a control means 22 so that the cooling waste heat accumulated in the heat accumulator tank 19 is discharged outside the train through the exterior heat exchanger 16. While, in a tunnel or in a station where cooling is not performed, the cooling waste heat is accumulated into the heat accumulator tank 19, and each solenoid valve 20a-20i is opening/closing-controlled so that the cooling waste heat is not discharged outside the train from the interior heat exchanger 16.

摘要： PURPOSE:To make a force of combustion variable in a wide range while keeping the combustion efficiency at a high level by a method wherein the quantity of a fuel supplied to a combustion chamber of the main body of a burner is made variable and the flow rate of air for combustion flowing into the combustion chamber is controlled in accordance with the quantity of the fuel supplied to the combustion chamber. CONSTITUTION:In a pulse burner, a fan 11 is stopped when the degree of opening of a fuel flow control valve 10 is the standard one. When the degree of opening of the fuel flow control valve 10 is increased so as to increase a force of combustion, an opening degree signal is sent to a fan control element 12. Based on this signal, the fan control element 12 makes the fan 11 rotate normally and controls the number of rotations thereof to be the one corresponding to the degree of opening, i.e. the number of rotations corresponding to the quantity of a fuel flowing into a combustion chamber 1. When the degree of opening of the fuel flow control valve 10 is decreased below the standard one so as to reduce the force of combustion, the fan control element 12 makes the fan 11 rotate reversely to make it correspond to the reduced quantity of the fuel flowing into the combustion chamber 1 and controls the number of rotations to be corresponding to the reduced quantity. Accordingly, combustion in the amount of combustion corresponding to the quantity of the fuel is attained with the air ratio fixed substantially.

摘要： PURPOSE:To ensure the supercooling cancelling operation so as to improve the reliability by providing an electronic refrigerating element whose heat releasing surface is thermally in contact with a heat exchanger with its heat absorbing surface covered with a heat insulating material which is impermeable to water, and disposing an orifice in the heat insulating material to allow a part of the heat absorbing surface to contact a latent heat storage material. CONSTITUTION:A heat storage tank 21, a latent heat storage material 22, a heat exchanger 23, an electronic refrigerating element 24, a control device 26, etc., are provided. The heat absorbing surface 37 and side surfaces of the body proper 35 of the electronic refrigerating element 24 are covered with a water-impermeable heat insulating material 38 in a liquid-tight manner. With a holder 39 set in place, an orifice 41 is drilled to allow a very small part of the heat releasing surface 37 to be exposed to the latent heat storage material 22. At the time of releasing heat, the temperature quickly becomes lower than the stable supercooling limit temperature when the heating medium is circulated to the heat exchanger 23 and the power is supplied to the electronic refrigerating elements body proper 35 at the moment when the temperature has dropped to the set temperature, because most of the heat absorbing surface 37 is covered with the heat insulating material 38 which is impermeable to water. As a result. the latent heat storage material in the orifice 41 is cancelled its supercooling condition. resulting in the cancellation of supercooling for the entire latent heat storage material so as to release the latent heat outside.

摘要： PURPOSE: To bring about a supercooled state easily by thermally fusing a heat storage material through a refrigerant type heat exchanger disposed in a heat storage tank filled with a latent heat storage material and a heating means fixed to the wall face of the heat storage tank thereby fusing a supercooling stabilized latent heat storage material without increasing the condensation pressure of a heat pump unit. CONSTITUTION: At the time at heat storage heating operation, refrigeration cycle is turned on in a heat pump 10 and a refrigerant circulates through the heat exchanger 4 in the heat storage unit 1 of a compressor - an indoor heat exchanger 15- an expansion valve 14- an outdoor heat exchanger 13- the compressor 11. At the same time, a heater switch 23 is closed to conduct a heater 5 and a heat storage material 3 is heated by the refrigerant from the heat exchanger 4 and the heat from the heater 5. When the temperature of the heat storage material 3 detected by a temperature sensor 7 exceeds the phase transition temperature, the refrigeration cycle and the heater 5 are turned off upon elapsing a time set by a timer 24. Since the heat storage material 3 is heated through combination of the heat exchanger 4 and the heater 5, heating time can be shortened by a factor of 3/2 without raising the refrigerant temperature resulting in the significant enhancement of heating performance.

摘要： PURPOSE: To realize comfortable heating by providing an opening/closing bypass valve coupled in parallel with a radiation heater and opening the bypass valve only for an interval to be elapsed before specified conditions are prepared after starting the heating operation thereby effecting radiation heating in parallel at the time of heating operation. CONSTITUTION: At the time of steady heating operation, high temperature refrigerant delivered from a compressor 1 flows through a radiation heater 4 into an indoor side heat exchanger 6. Consequently, the radiation heater 4 is heated up to high temperature and radiation heating takes place. On the other hand, the indoor side heat exchanger 6 radiates heat through forced convection and a room is heated through both radiation heating and forced convection. A bypass valve 10 is opened only for an interval to be elapsed before specified conditions are prepared after starting the heating operation. Since the refrigerant delivered from the compressor 1 does not pass through the radiation heater 4 but Flows directly into the indoor side heat exchanger 6 at the time of starting the heating operation, radiation of heat from the indoor side heat exchanger is enhanced through forced convection and indoor temperature rise is quickened resulting in comfortable heating.

摘要： PURPOSE:To avoid a cost increase due to using the dielectric heating of microwaves and prevent microwave leakage outside the unit by using an electric heater as a heat source. CONSTITUTION:Kitchen refuse 8 is thrown into the incinerating chamber 4 from the kitchen refuse chute 2 by opening a door 3. An ash discharge plate 11 is kept open, and the moisture in the kitchen refuse 8 is drained from the water drain 12. Then, an electric heater 7 is energized to heat the casing 5, and a fan 18 is operated to set the air feed and vent system in motion. During the early heating process, the moisture remaining in the kitchen refuse 8 is evaporated, and, in the advanced stage of drying where the temperature exceeds 100 deg.C and most of the moisture is lost, the temperature rises rapidly and fire is started. The electric supply to the heater 7 is stopped once the ignition takes place. The resultant exhaust gas is deodorized by an exhaust gas processing means 20, and then is discharged out of awn exhaust gas discharge opening 17. After the incineration is done, the ash is removed out of the unit by opening an ash removal plate 11.

摘要： PURPOSE:To make it possible to release for sure a latent heat accumulating material of supercooling without accompanying deterioration heat accumulating material by providing a drive device to make a source material holding member which holds the source material of a latent heat accumulating material to be brought in temporally contact with the heat accumulating material in a heat accumulating tank. CONSTITUTION:When the instruction to move the state of supercooling is given to a control circuit 18, a switch is turned ON by the control of the control circuit 18 and a spring 12 made of a shape memory alloy 18 energized and generates heat, and when its temperature reaches a temperature above the point of it transfermation, the spring starts to shrink due to the shape memory effect. With this shrinking, a source material holding member 8 is lowered and its tip end section makes a contact with the surface of a latent heat accumulating material 4 in a heat accumulating tank 1. The heat accumulating material is at once released from the state of super-cooling by the contact with the source material 9 and starts to solidify, releasing the latent heat. When the rise in the temperature of the heat accumulating material 4 is detected by a temperature sensor 17, the contact of the source material holding member 18 and the heat accumulating material 4 is detected by the control circuit 18. Next, the control circuit 18 turns the switch 15 OFF and stops the electric current to the shape memory alloy spring 12. When the effect of shape memory is gone, the source material holding member 8 is lifted by the restoring force of a material holding member 8 is lifted by the restoring force of a bias spring 13 and placed away from the heat accumulating material.
