Abstract
Description
本発明は、熱交換機利用の省エネ方式の液加温装置に関する。 The present invention relates to an energy-saving liquid heating device using a heat exchanger.
液加温装置において、省資源と、低コストであって、しかも効率的な装置が、必要とされている。これらを充足し、かつ省資源化が図れる、プレート式の熱交換機の利用が最適であり、昨今の市場で必要とされる。 There is a need for a liquid warming device that is resource-saving, low-cost, and efficient. It is optimal to use a plate-type heat exchanger, which satisfies these requirements and saves resources, and is needed in the current market.
その最たるものが、熱交換機利用の省エネ方式の液加温装置（カーボンニュートラル対応型の液加温装置）と考えられる。その為には、冷媒と、循環方式、又は使用機器等の選択と、組合せが必要である。 The most important example is an energy-saving liquid heating device that uses a heat exchanger (a carbon neutral liquid heating device). For this purpose, it is necessary to select and combine the refrigerant, circulation method, and equipment used.
以上の観点を考慮し、先行文献を調査した結果では、加温する対象物（洗浄装置、食品、又は空調機と、その液類）、商品（タンク）、又は販売ルート（販売システム）において、熱交換機（ヒートポンプ）対応の加温機器に関する構造が挙げられる。 Taking into account the above points of view, the results of a survey of prior literature show that in objects to be heated (cleaning equipment, food, or air conditioners and their liquids), products (tanks), or sales routes (sales systems), An example is a structure related to a heating device compatible with a heat exchanger (heat pump).
例えば、文献（１）（特許第３５１６４７６号）に記載の「食品殺菌装置、空調装置その他の機器において、機器の内部配管や接続配管が食品、スチーム、水等で汚染された場合等において、流体残渣を除去、洗浄する洗浄装置（洗浄装置）」がある。要点は、洗浄液をあらかじめ設定温度に昇温できる洗浄液タンクを設けて、洗浄時にこの洗浄液を利用し汚染の全く生じない洗浄装置とすることであって、例えば、プレート式熱交換器等を利用した間接加熱器で、スチーム等の熱媒を間接加熱器の一方流路に供給し、かつスチームトラップで、一方流路の出口側に設けられ、熱交換後発生するスチームドレンを排出し、昇温動作でポンプが動き、循環配管の洗浄液が流れると同時に、間接加熱器により、洗浄液を昇温し、熱媒はスチームドレンとなりスチームトラップより排出される構造である。 For example, as described in Document (1) (Patent No. 3516476), "In food sterilizers, air conditioners, and other equipment, when the internal piping or connecting piping of the equipment is contaminated with food, steam, water, etc., There is a "cleaning device (cleaning device)" that removes and cleans residue. The key point is to install a cleaning liquid tank that can heat the cleaning liquid to a preset temperature and use this cleaning liquid during cleaning to create a cleaning device that does not cause any contamination. An indirect heater supplies a heat medium such as steam to one flow path of the indirect heater, and a steam trap is installed at the outlet side of the other flow path to discharge the steam drain generated after heat exchange and raise the temperature. When the pump moves and the cleaning liquid flows through the circulation piping, an indirect heater raises the temperature of the cleaning liquid, and the heating medium becomes a steam drain and is discharged from the steam trap.
又、文献（２）（特許第６０６８０４６号）に記載の「コンビニエンスストア、スーパーマーケット等の店にパンや惣菜等の物品を大量に納品する場合に使用される容器、例えば、プラスチック製のトレー、パレット、コンテナ等搬入後、各店から回収されて何段にも積み重ね容器の洗浄装置（容器洗浄装置）」がある。要点は、容器洗浄装置は、洗浄機と、ヒートポンプを備える循環加熱式の温水供給ユニットを有し、洗浄機は、洗剤の入っている水である洗浄水を循環させ、順次、送られてくる容器を洗浄し、また、温水供給ユニットは、所定の温度、例えば、６０℃の加温水を循環して洗浄機側に供給し、洗浄機側の洗浄水を加温して温度を上げるための装置を備える。そして、熱交換器は、多管円筒式熱交換器で、円筒胴内には多数本の伝熱管が円形状に配列されている。 In addition, as described in Document (2) (Patent No. 6068046), "Containers, such as plastic trays and pallets, used when delivering large quantities of goods such as bread and prepared foods to stores such as convenience stores and supermarkets" There is a cleaning device (container cleaning device) for containers that are collected from each store after being delivered and stacked in multiple tiers. The main point is that the container cleaning device has a washing machine and a circulating heating type hot water supply unit equipped with a heat pump. The hot water supply unit circulates heated water at a predetermined temperature, for example, 60°C, and supplies it to the washing machine to heat the washing water on the washing machine to raise the temperature. Equipped with equipment. The heat exchanger is a multi-tube cylindrical heat exchanger, and a large number of heat transfer tubes are arranged in a circular shape within the cylindrical body.
文献（３）（特許第３９７０２２１号）に記載の「貯湯タンク内の高温の湯を追い焚き用熱交換器の加熱部側へ流した後、熱交換後の温度低下した湯水をヒートポンプ冷媒回路で加熱してから貯湯タンクに戻すことにより、加熱能力に優れた追い焚き機能付きのヒートポンプ給湯装置（ヒートポンプ給湯装置）」がある。要点は、ヒートポンプ給湯装置は、ヒートポンプユニット、給湯ユニットでなる。ヒートポンプ給湯装置から湯が供給される浴槽であって、ヒートポンプユニットは、加熱部を流れる二酸化炭素冷媒は、冷媒対水熱交換器の被加熱部側に流れる湯水を、熱交換によって９０℃以上に加熱する構造である。 Document (3) (Patent No. 3970221) states, ``After flowing high-temperature hot water in the hot water storage tank to the heating part side of the reheating heat exchanger, the hot water whose temperature has decreased after heat exchange is passed through the heat pump refrigerant circuit. There is a heat pump water heater with a reheating function that has excellent heating capacity by heating water and then returning it to the storage tank. The key point is that a heat pump water heater consists of a heat pump unit and a hot water supply unit. The bathtub is supplied with hot water from a heat pump water heater, and in the heat pump unit, the carbon dioxide refrigerant flowing through the heating part heats the hot water flowing to the heated part side of the refrigerant-to-water heat exchanger to 90°C or higher by heat exchange. It has a heating structure.

Regarding the temperature rise and clarification of the processing fluid of contaminated processing water (contaminated processing oil) such as scraps and chips, indirect heating should not be intended, especially (a) Effective use of air heat (evaporator) However, it is not intended to reduce costs or achieve continuous heating treatment. In addition, 2) Utilizing a compressor, compresses the refrigerant and achieves a high temperature of the refrigerant, and 3) Transfers heat to water using the high temperature refrigerant, making full use of the function of the indirect exchanger, and reducing the cleaning liquid. d) I think it is impossible for the expansion valve and the fan to prepare for the efficient intake of air heat into the refrigerant that has lost its heat.
