摘要： PROBLEM TO BE SOLVED: To provide a small and space-saving instant water heater type heat pump hot water supply device having the sufficient hot water supply capability even if the size of a heat pump cycle is restrained, and a wide flow rate range and capable of supplying hot water at a large flow rate even if capacity of a tank is made small. SOLUTION: This heat pump hot water supply device adds and uses hot water from a water passage 33 and hot water of a previously stored tank 21 by respectively taking out the hot water from a first hot water supply pipe 43 and a second hot water supply pipe 53 by instantly heating tap water by directly feeding the water to the water passage 33 of a hot water supply heat exchanger 34 for exchanging heat between a second radiator 26 and the water passage 33, and controls at least one of respective hot water appearing temperature or hot water appearing flow rate from the first hot water supply pipe 43 or the second hot water supply pipe 53, and thus, can cope with a wide flow rate range, and can reduce an installation space by reducing the tank capacity without requiring the large-capacitated hot water supply heat exchanger 34.

摘要： PROBLEM TO BE SOLVED: To miniaturize and arrange a heat pump type water heater in a pipe space of a multiple dwelling house. SOLUTION: A heat sink 16 and a heat accumulating means 28 are vertically arranged so that either becomes the upper side, and are constituted so that air sucked by an air blowing means 18 passes through the heat sink 16 by flowing through a back face of a casing 42 and at least one side surface. Thus, since a large quantity of air flows in the casing 42 and passes through the heat sink 16, a lateral width of the water heater can be particularly reduced while providing sufficient heat pump heating capacity.

摘要： PROBLEM TO BE SOLVED: To generate rich mixture fully mixed, reduce fuel supply rate to rich flame, and achieve ultralow NOx.
SOLUTION: This combustion device is provided with a first bent part 63 for downward bending a horizontally extending rich mixture passage 59 starting from a rich fuel/air introduction port 58, and a second bent part 64 for horizontally bending the downward extending rich mixture passage 59. In both of the bent parts, the air-fuel mixture gas flow is disturbed, and the mixing is accelerated, and the uniform rich mixture is generated. Thus, the fuel supply rate to the rich flame for stabilizing lean flame can be reduced. Therefore, it is possible to restrain CO and HC while achieving ultralow NOx, and it is also possible to restrain the noise.

摘要： PROBLEM TO BE SOLVED: To realize low NOx, a wide input variable range, reduction of noise, and restraint of unburned components, for a low-NOx burner.
SOLUTION: Burner port divided plates 21a, 21b include wavy portions 22 whose cross section in the longitudinal direction is of wavy type respectively, and are formed with lean burner ports 25 which are sub-devided such that the vicinities of tops 23 of the wave portions 22 are made substantially circular arc-shaped, and the tops 22 are arranged so as to be in close contact with each other. The respective burner port divided plates 21a, 21b are prevented from being deformed, thus preventing generation of back fire at the time of small inputs and increasing the input variable range. A burner port area is maximized, while the lean burner ports 25 partitioned by the minimum number of burner port divided plates are being formed, therefore lean mixture jets at a low velocity, so that a short lean flame with a stable flame length is formed, thus achieving reduction of noise and restraint of the unburned components.

摘要： PROBLEM TO BE SOLVED: To achieve stabilization of flames and further reduction of NOx. SOLUTION: A combustion device is provided with a first burner port 16 for ejecting lean mixed gas, a second burner port 20 which is provide close to the first burner port 16, for ejecting rich mixed gas, and a third burner port 23 which is provided close to the second burner port 20, for ejecting mixed gas whose concentration is lower than that ejected from the burner port 20. The ejection speed of the lean mixed gas ejected from the first burner port 16 is rendered to be higher than the ejection speed of the mixed gas ejected from the second burner port 20 and the third burner port 23, respectively. In such a structure, the rich mixed gas ejected from the second burner port 20 is thermally decomposed by stabilized flames above the third burner port 23, and the resultant active chemical species is diffusedly fed to the base of thin flames to form a 'high temperature and highly reactive region' which actively conducts combustion reaction. Thus, stabilized and ultralow NOx combustion can be achieved in a condition where high-speed lean mixed gas is fed.

摘要： PROBLEM TO BE SOLVED: To improve combustibility. SOLUTION: A combustion device is independently provided with a thin combustion portion 20 for spouting thin pre-mixed gas, a first thick combustion portion 23 which is located close to a thin burner port 22 for spouting first thick pre-mixed gas, and a second thick combustion portion 26 which is located close to a first thick burner port 25 for spouting second thick pre-mixed gas. Combustion density can be accurately set based on the opening diameter of a thin nozzle 30, a first thick nozzle 32 and a second thick nozzle 34, and based on the opening area of a thin entrance portion 29, a first thick entrance portion 31, and a second thick entrance portion 33 so as to ensure combustibility. As a 'high temperature and high reaction region' is formed in a minute space made at the end of the burner port 22, the burn rate of the thin mixture is increased or the fuel concentration of the thin mixture is reduced, and in addition, NOx is reduced and the variable range of the fuel amount is broadened.

摘要： PROBLEM TO BE SOLVED: To obtain combustion equipment, in which prevention of pulsating combustion and NOx reduction can be attained. SOLUTION: A burner-port group A is composed of a lean burner-port 10 to let out lean-premixture, a first burner port 11 provided adjacently to the port 10, letting out first rich-premixture, and a second burner port 12 provided adjacently to the port 11, letting out second rich premixture. The combustion equipment comprises a plurality of the groups A to constitute an alternate arrangement of a thin fuel flame 24 on the port 10, a first thick-fuel flame 25 on the port 11, and a second thick fuel flame 18 on the port 12. Thus, the pulsating combustion and its propagation can be prevented from being generated due to agreement of natural frequencies of symmetrically distributed thick flames on both sides of thin flames, as is often in the case of the conventional art. The flame 24 is stabilized on both sides by the first and second flames 25 and 26, so the combustion rate of the lean mixture can be increased, and the concentration of the lean mixture is reduced, and NOx reduction can be attained further.
