Stainless steel small capillaryAny tube with a very thin inner diameter is called a "capillary tube". Usually refers to a thin tube with an inner diameter equal to or less than 1 mm. It is called a capillary because the diameter of the tube is as thin as hair. For example, mercury thermometers, slits in the tip of a pen, gaps between towels and blotting paper fibers, crevices in the soil structure, and the veins of plant roots, stems, and leaves can all be considered capillaries. When the water tank coil of a conventional air energy water heater is heating, following the heat exchange with the tank body, the measurement of the refrigerant in the coil will always rise, and there is often no heating of the inner tank around the coil inlet. There will be the title of uneven water temperature at the same location, and this heat exchange method will constitute a trivial pressure that is too high and affects the service life.

The two-way parallel entanglement method ensures that every part of the inner tank is evenly heated, which increases the trivial pressure and extends the service life of the unit. However, Gree Electric, which has strict requirements on the quality of goods, did not hesitate to choose 304L stainless steel with better anti-corrosion performance and better riveting performance. According to the introduction of the industry: 304L and 304 have only one more letter in the title, but the carbon content is very different from the chromium and nickel content. The corrosion resistance and riveting performance of 304L material are compared with that of 304. Steps. Different from the conservative atmosphere energy water heater that uses capillaries as a diet component, an electronic constriction valve is now used as a saving element.

Change the multi-saving control to the adaptive control method, which satisfies the trivial active scheduling under different measurement conditions, the refrigerant flow is more accurate, and it is more energy-efficient than the general stainless steel capillary saving method. The jubilation device generates heat energy to preheat the working fluid from the near conditions. After the working fluid steam is compressed by the compressor, the measurement and pressure drop form low-temperature steam. When the low-temperature steam is condensed into a solid by the condenser, the released heat energy is transferred to the storage. Water in the water tank. The condensed preheated working fluid goes to the jubilator through the shrink valve, and then is jubilated again, thereby realizing the heating cycle.
