摘要： Provided are a scale deposition device and water heater using such a scale deposition device which allow efficient deposition of a scale component dissolved in water so as to reduce adhesion of the scale to a heat-transfer channel. The water heater comprises: a scale deposition device including a tank, scale deposition means including an anode and a cathode provided in the tank so as to be opposed to each other, and a first power supply for applying a voltage between the anode and the cathode, the scale deposition means depositing a scale component dissolved in water retained in the tank; a heat-transfer channel provided at downstream of the scale deposition means, for guiding the water; and a heat source for heating the water by heat exchange in the heat-transfer channel, in which the scale deposition means includes oxygen-gas supplying/dissolving means for supplying an oxygen gas to a water feed pipe for feeding the water to the tank and dissolving the oxygen gas in the water.

摘要： There is provided a water heater in which scale adhesion to the inner wall of a liquid to-be-heated flowing channel in a heat exchanger that constitutes the water heater is reduced, and lowering of heat transfer performance and obstruction of the flow channel due to the scale adhesion is reduced. By applying pulsation of a liquid to be heated which circulates between a tank (1) and a heat exchanger (3), scale that has been deposited on the inner wall (heat-transfer surface) of a liquid to-be-heated flow channel (31) in a heat exchanger (3) is detached, and the number of times of circulation of the liquid to be heated which circulates between the tank and the heat exchanger is controlled to be three times or less. A distribution control unit (101) pulsates the to-be heated liquid that passes through the liquid to-be-heated flow channel (31) of the heat exchanger (31), and also controls a flow rate of the liquid to-be-heated which passes through the liquid to-be-heated flow channel (31) so that the number of times of circulation indicating the number of times at which the entire volume of the liquid to-be-heated stored in the tank (1) passes through the heat exchanger (3) is three times or less. The number of times of circulation is determined, based on the entire volume of the liquid to-be-heated stored in the tank (1), a boiling time to be taken for the entire volume of the liquid to-be-heated in the tank (1) to reach a predetermined temperature, and the flow rate of the liquid to-be-heated which passes through the liquid to-be-heated flow channel (31).

摘要： To improve the separation efficiency of a gas-liquid separator in the gas-liquid separator and an air conditioner, the gas-liquid separator having a vessel with an inlet pipe and an outlet pipe is arranged such that an exit end section of the inlet pipe is formed to be closed or to have a gap, an expanded end section having a width greater than the diameter of that portion of the inlet pipe which crosses a container of the gas-liquid separator is provided, and that a lateral hole is formed in a side face of the expanded end section. Refrigerant vapor and refrigerant liquid are efficiently separated from each other at the expanded end section, and this improves separation efficiency of the gas-liquid separator.

摘要： A plate fin tube-type heat exchanger has fins (1) layered with spacings and heat transmission tubes (2) penetrating the fins (1) in the layering direction. In the heat exchanger, fluid inside the heat transmission tubes and fluid outside the heat transmission tubes exchange each other heat through the heat transmission tubes (2) and the fins (1). Each fin (1) has bridge-like cut-and-raised portions (3) each constituted of leg portions and a beam portion. The cut-and-raised portions (3) are arranged only in the area satisfying the following expressions: Ws = (1 - phi)Dp + phiD, phi > 0.5 where, for each heat transmission tube (2), Ws is an expansion width of cut-and raised portions in the direction (step direction) along a fin edge portion on the upstream side of the fluid outside the heat transmission tubes and D is the outer diameter of each heat transmission tube, and Dp is an arrangement spacing of the heat transmission tubes in the step direction.
