本発明は2種類の温度−圧力特性の異る金属水素化合物
の水素の吸紙及び放出のときに出る熱エネルギーを利用
し給湯温度を上げることに関する。[Detailed Description of the Invention] [Field of Application of the Invention] The present invention raises the temperature of hot water by utilizing the thermal energy released when two types of metal hydride compounds with different temperature-pressure characteristics absorb and release hydrogen. Regarding.

る欠点があった。As shown in FIG. 1, in a conventional heat pump water heater, the latent heat of condensation of a high-temperature, high-pressure gas refrigerant discharged from a compressor 12 is used in a water-refrigerant heat exchanger 8 to circulate water in a hot water storage tank 1 through a pipe 5. As a result, the water in the hot water storage tank 1 is heated, becomes a high-pressure liquid refrigerant, passes through the expansion valve 9, and enters the outdoor heat exchanger 10 as a low-temperature, low-pressure liquid refrigerant. Here, it absorbs the latent heat of vaporization from the outdoor air and becomes a low-pressure gas refrigerant, which drives the compressor 12.
Hot water is supplied by heating the water in the hot water storage tank l by inhaling the water into the water/refrigerant heat exchanger 8.
When the temperature rises, the discharge pressure of the compressor 12 increases rapidly, so the input to the compressor 12 also increases, resulting in a decrease in the coefficient of performance.
本発明の目的は上記の欠点を改良するためになされたも

転は停止して、水素吸蔵仕金の発熱反応を利用して高温
の給湯を得るようにしたものである。The purpose of the present invention was to improve the above-mentioned drawbacks, and the operation in the high temperature range, which is a drawback of heat pump water heaters, is stopped, and hot water is supplied at high temperatures by utilizing the exothermic reaction of the hydrogen storage metal. This is what I did to get it.

させるのである。In other words, when hot water is supplied by utilizing the property of metal flies, which have different temperature-pressure characteristics, to absorb heat exothermically to form metal hydride compounds, and to absorb heat reversibly to release hydrogen, it is possible to When hot water is used to heat a metal hydride compound stored in a container outside the hot water storage tank, the hydrogen in the container absorbs heat, is stored in the container in the hot water storage tank, and generates heat, causing the hot water to be heated. It raises the temperature.
以下本発明の一実施例を第2図により説明する。 An embodiment of the present invention will be described below with reference to FIG.

壁には放熱が速かにできるようにフィンが付けである。A container 2 provided at the top of the hot water storage tank 1 and a container 3 provided outside the hot water storage tank 1 are filled with a metal compound and communicated through a communication pipe 4 so that hydrogen can flow therethrough. The outer wall of the container 3 is provided with fins to quickly dissipate heat.

上部に接続されている。次に作動を説明する。Further, the container 3 has a structure that allows indirect heat exchange between the hot water sent by the pump 5 and the metal compound. Furthermore, water on-off valves 13 and 14 are provided at the outlet of the pump 5, and the water can be circulated to the water heat exchanger 8 of the heat pump water heater, which is connected to the upper part of the hot water storage tank. Next, the operation will be explained.

り出湯できることになる。The refrigerant compressed by the compressor 12 becomes a high-temperature, high-pressure gas that enters the water-refrigerant exchanger 8 and is circulated by the pump 5 through the on-off valve 1.
4, enters the water/refrigerant heat exchanger 8, undergoes heat exchange, and enters the hot water storage tank 1 from above. When the temperature of the circulated hot water reaches the set temperature, the compressor 12 is stopped, and when hot water is supplied from the faucet 6, the on-off valve 13 is opened and 14 is closed, and the pump 5 is operated, so that the hot water passes through the container 3 and enters the hot water storage tank. I can do it. At this time, the hydrogen storage alloy filled in the container 3 emits hydrogen endothermically and enters the container 2 through the communication pipe 4. When the metal alloy absorbs hydrogen exothermically and forms a metal compound, inside the hot water storage tank 1. This means that hot water with a higher temperature can be dispensed from the faucet 6.

済的な給湯機を提供することができる。Therefore, according to the present invention, the compressor 12 is operated by stopping the compressor 12 when the temperature of the water at the inlet of the water-refrigerant heat exchanger 8 becomes high, and generating heat when the hydrogen storage alloy absorbs the water flow during hot water supply. If this is used, high-temperature hot water can be dispensed only by operating the pump 5, so that an economical water heater without lowering the coefficient of performance can be provided.
