An air energy water heater

Abstract

The invention provides an air energy water heater, and relates to the field of water heaters. The air energy water heater comprises a heat exchange box, wherein a heat exchange tube is arranged in theheat exchange box; the top end of the heat exchange tube is fixedly connected to a first rotary mechanism; the heat exchange tube communicates with the inner part of the rotary mechanism; the first rotary mechanism is fixedly arranged in the heat exchange box; the bottom end of the heat exchange tube is fixedly connected to a second rotary mechanism; and the second rotary mechanism is fixedly arranged in the heat exchange box. In the air energy water heater, the heat exchange tube rotates to generate friction with water, so that attachment of water scales is reduced, heat conduction of the heat exchange tube is guaranteed, water molecule motion speed can be increased, and therefore, heat exchange efficiency is improved, flowing time, in the heat exchange tube, of a medium is shortened, and the high-temperature medium is in sufficient contact with a heat exchanger to improve heat exchange degree; meanwhile, the medium can be sufficiently liquefied after releasing energy, so that a throttle device connected behind the heat exchanger is protected; and a connecting shaft is kept in sealing with the first rotary mechanism and the second rotary mechanism through a sealing ring.

Description

technical field [0001] The invention relates to the field of water heaters, in particular to an air energy water heater. Background technique [0002] Air source water heater, also known as "air source heat pump water heater". "Air energy water heater" absorbs the low-temperature heat in the air, vaporizes it through the fluorine medium, and then compresses it through the compressor to increase the temperature, and then transforms it into the water through the heat exchanger to heat it. The high-temperature heat energy after compression is used to heat the water temperature. The medium releases heat to the water in it, condenses and liquefies, and enters the heat exchanger through the throttle valve to start the next cycle. The air energy water heater has the characteristics of high efficiency and energy saving. The same amount of hot water produced is 4-6 times that of ordinary electric water heaters. , its annual average thermal efficiency ratio is 4 times that of electri...

Problems solved by technology

[0003] However, due to the different hardness of the heated water, after the impurities in the water are heated, especially when the temperature is higher than 70 degrees Celsius, the formation rate of scale increases sharply, while the temperature of the heat exchanger of the air energy water heater can reach 85 degrees Celsius, and the thermal conductivity of the scale is poor. Scale adheres to the heat exchange tube, which affects the thermal conductivity of the heat exchange tube, thereby affecting the water heating efficiency
