加热如何改变清洁力：温度破坏油脂分子键

How heat changes cleaning power: temperature breaks grease bonds

冷水机仅靠高压水射流的机械力冲走浮尘与松散污垢；热水机在 60–95°C（部分蒸汽机型可达 100–155°C）下，用热量破坏油脂、油品、食物残渣与表面的分子结合力。行业实测显示，针对含油、含脂、生物类污垢，热（70–90°C）+ 压（120–200 bar）+ 流（12–18 L/min）的组合远胜于单纯压力。

Cold-water units rely only on the mechanical force of a high-pressure jet to dislodge loose dust and debris. Hot-water machines heat water to 60–95°C (some steam models reach 100–155°C), using thermal energy to break the molecular bonds holding grease, oil and food residue to a surface. Field data shows that for oily, fatty and biological soiling, the combination of heat (70–90°C) + pressure (120–200 bar) + flow (12–18 L/min) far outperforms pressure alone.

何时必须用热水：油污、食品安全与杀菌

When hot water is essential: grease, food safety and sanitizing

以下场景建议优先热水机型：餐饮后厨与排油烟区深层去油、食品工厂 HACCP 卫生（去除脂肪与蛋白）、汽修车间发动机舱与底盘脱脂、屠宰/肉制品加工的生物污垢、冷链与冷藏车除脂。热水还能杀灭部分细菌、霉菌与藻类，减少化学剂用量。

Prioritise hot water for: deep degreasing of restaurant kitchens and exhaust hoods, HACCP sanitation in food factories (fat and protein removal), engine-bay and underbody degreasing in auto workshops, biological matter in slaughterhouses and meat processing, and fat removal on cold-storage and refrigerated vehicles. Hot water also kills some bacteria, mould and algae and reduces detergent consumption.

何时冷水已足够：尘土、泥沙与一般污垢

When cold water is enough: dust, mud and general dirt

清洗建筑立面浮尘、车辆外观与车队外饰、混凝土/瓷砖/砌体的完工保洁、路面与户外硬地、涂装前预冲洗——这些以松散颗粒为主的任务，冷水机完全胜任，且购置与运维更低。

Cleaning facade dust, vehicle exteriors and fleet washing, post-construction concrete/tile/masonry, pavements and outdoor hard surfaces, and pre-rinse before painting are loose-particle tasks where cold water is fully adequate and cheaper to buy and run.

动力与加热方式：电加热 vs 燃油燃烧器

Power and heating method: electric heat vs fuel burner

电加热热水机可在室内安全使用；柴油/燃气燃烧器加热的机型需置于室外或通风良好处。常见工业压力区间 120–200 bar、流量 12–18 L/min。注意：加热模块（燃烧器、盘管、燃油系统）会带来额外部件与维护。

Electric-heated hot water units are safe indoors; diesel or gas burner units produce exhaust and must be used outdoors or in well-ventilated spaces. Typical industrial ranges are 120–200 bar pressure and 12–18 L/min flow. Note the heating module (burner, coil, fuel system) adds components and maintenance.

成本与运维：贵在哪、省在哪

Cost and upkeep: where it costs more, where it saves

热水机购置价更高（含燃烧器、加热盘管、燃料系统），维护项更多，机身更重；但因其清洁更快、化学剂更少、可杀菌，对高频油污作业，长期往往更划算。冷水机无燃烧器、部件少、更轻便、易维护。

Hot-water machines cost more to buy (burner, heating coil, fuel system) and need more maintenance, and are heavier. But because they clean faster, use fewer chemicals and sanitize, for high-frequency oily work they are often cheaper long term. Cold-water units have no burner, fewer parts, are lighter and easier to maintain.

按场景选型清单

Scenario-based selection checklist

① 主要脏污是油/脂/食物残渣 → 热水；② 以尘土/泥沙/一般污垢为主 → 冷水；③ 室内或通风受限 → 电加热；④ 户外重油污连续作业 → 柴油加热；⑤ 预算与机动性优先 → 冷水入门。

1) Main soil is oil/grease/food residue → hot water. 2) Mostly dust/mud/general dirt → cold water. 3) Indoor or poor ventilation → electric heat. 4) Outdoor heavy-grease continuous duty → diesel heat. 5) Budget and mobility first → cold-water entry model.
