摘要： PROBLEM TO BE SOLVED: To solve the problems in the conventional technology for suppressing a temperature of compressed air by injecting water into the intake air wherein the water is left inside an air compressor when it is stopped and it is locked if the water is frozen when a temperature is low. SOLUTION: The water for reducing a temperature of the compressed air is injected and supplied into a discharge port 36. Consequently, the water does not exist inside the screw compressor A when the screw compressor A is stopped. For this reason, even when an outside air temperature drops and a temperature of the screw compressor A drops below 0 deg.C, the water is not frozen and the screw compressor A is not locked. Since the screw compressor A is not locked due to frozen water in this way, the screw compressor A can be easily driven even when its temperature drops below 0 deg.C. Since excess load is not applied to a driving system of the screw compressor A naturally, the driving system is not damaged.

摘要： PROBLEM TO BE SOLVED: To reduce the size of a combustion cylinder by providing a cylinder for combusting fuel, and means for supplying combustion gas with cooling air and blowing the cooling air toward the downstream side of the combustion cylinder thereby increasing the combustion region of fuel in the combustion cylinder. SOLUTION: Liquid fuel supplied under high pressure from a fuel tank 1A by means of a fuel pump 1B is injected by means of an injector 1 and combusted. A flange 6 being coupled with a combustion air pump 4 is abutted against the open edge of a combustion cylinder 2 which is coupled, on the downstream side, with a cooling air pump (cooling air supply means) 10 for lowering the blow-out temperature of combustion gas by supplying cooling air. A control means 15 operates the injector 1, the combustion air pump 4, the cooling air pump 10, and the like, to inject a small quantity of fuel and to supply combustion air. Since the blow-out temperature of combustion gas is lowered by supplying cooling air, the structure is simplified and a large volume of hot air having lowered temperature is supplied to a part being warmed.

摘要： PROBLEM TO BE SOLVED: To provide combustion equipment capable of both of instantaneous firing and stable continued combustion. SOLUTION: In combustion equipment there are provided a firing air hole 6 for supplying a small quantity of primary air suitable for firing to the neighbourhood of a firing point X as an air hole for blowing out combustion air into a combustion chamber 1, and a primary air hole 7 disposed more downstream than the firing point X for supplying a large amount of secondary air. The firing air hole 6 and the primary air hole 7 are obtained by connecting a piping branched from an air pump 3, and there is provided a pressure opening/ closing valve 8 between a branch point Y and the primary air hole 7 for closing the primary air hole 7 upon instantaneous firing. Upon starting a small amount of primary air suitable for firing is supplied from the firing air hole 6 to the neighbourhood of the firing point X at an initial stage of building-up of the air pump 3 (when there is a slight flow rate) so that instantaneous firing is allowed, and as the building-up flow rate of the air pump 3 is increased, secondary air is supplied from the primary air hole 7 to the combustion chamber 1 to ensure stable continuous combustion.

摘要： PROBLEM TO BE SOLVED: To restrain occurrence of clogging of fins in a low-temperature outdoor air passage which introduces outdoor air. SOLUTION: In a heat exchanger, the pitch of a fin 2 arranged in a low- temperature outdoor air passage B is set to be wider than the pitch of the fin 2 arranged in a high-temperature indoor air passage A. Therefore, even if dust and the like intrude together with outdoor air, there is only a low possibility for a foreign matter having intruded to pass through the fin 2 and cause clogging of the same. As a result, the function of the heat exchanger can be prevented from degrading over the long term.

摘要： PROBLEM TO BE SOLVED: To equally supply an air circulation path with a high-temperature or low-temperature air stream, in the case of letting the high-temperature air stream and the low-temperature air stream adjacently thereby performing heat exchange and cooling the high-temperature air stream. SOLUTION: In case that centrifugal fans 3 and 4 are each of right rotation, the centrifugal fans 3 and 4 are arranged eccentrically so that wide space can be secured at the rights of the fans in condition that heat exchangers 2 are temporarily arranged downward, respectively. For the centrifugal fans 3 and 4, to increase the quantity of air blasting to the space in rotational direction, much air blasting is performed to the side of wide space, consequently the quantities of air blasting to each high-temperature air circulation path A and each low-temperature air circulation path B are equalized.

摘要： PROBLEM TO BE SOLVED: To provide a boiling cooler having high cooling performance and excellent in high volume productivity. SOLUTION: A porous sintered material 6 is arranged along a heat receiving wall 7 and refrigerant standing at the lower section is transported to the vicinity of a heater fixing part 6a through capillarity of the porous sintered material 6. Since the refrigerant is boiled in the vicinity of a heater fixing part 6a over a relatively wide range, degree of superheating is reduced at the heater fixing part 7a. Since liquid refrigerant standing at the lower section in a container 5 is transported through the porous sintered material 6, condensing area of heat dissipating wall 8 not immersed into the liquid refrigerant is increased and degree of supercooling of the heat dissipating wall 8 is reduced. More specifically, cooling capacity of a boiling cooler 1 is enhanced through reduction of degree of superheating and supercooling.

摘要： PROBLEM TO BE SOLVED: To obtain a cooler employing a heat exchanger for exchanging heat between high temperature inner air and low temperature outer air in which conventional problems, i.e., low efficiency of crossflow heat exchanger and high pressure loss of opposed flow heat exchanger, are solved. SOLUTION: The heat exchanger comprises rectangular barrier walls 2 and corrugate fins 3 laminated alternately and first and second passages A, B for passing high temperature inner air and low temperature outer air, respectively, in the form of vertically elongated box. Inner fins 3 are arranged while inclining forward and the inlet Ai and outlet Ao of the first fluid passage A are provided, respectively, above and below while the inlet Bi and outlet Bo of the second fluid passage B are provided, respectively, below and above so that the high temperature inner air and the low temperature outer air flow oppositely. Since the flow-in area of the tin 3 is increased significantly as compared with a conventional opposed flow heat exchanger, pressure loss is reduced and clogging is suppressed.
