    SUMMARY:
    The ultra-high-temperature cascade hot water machine has greatly promoted our company’s ability to occupy the ultra-high-temperature industrial hot water market. Under the general trend of coal-to-electricity, the ultra-high temperature effluent of the ultra-high Kang air energy heat pumps better occupy the market in the field of industrial hot water!

    The basic operating principle of the cascade air source heat pump unit is based on the principle of reverse card circulation. The working fluid system is divided into a low-temperature circulating system and a high-temperature circulating system. The low-temperature liquid working fluid first absorbs the heat in the air in the fin heat exchanger The evaporation becomes a low-temperature and low-pressure gas. The low-pressure gas is compressed by a low-temperature compressor into a medium-temperature and medium-pressure gas, which enters the intermediate heat exchanger and is condensed into a liquid to release heat. The liquid working fluid is decompressed and expanded by the expansion valve and then returns to the fins. In the heat exchanger, the heat of evaporation is absorbed again to complete a low-temperature cycle; at the same time, the high-temperature liquid working fluid absorbs the heat transferred by the low-temperature stage in the intermediate heat exchanger and evaporates into a medium-temperature and low-pressure gas, and the low-pressure gas is compressed by a low-temperature compressor The medium-temperature and medium-pressure gas is compressed into high-temperature and high-pressure gas by the high-temperature compressor, which enters the hot water heat exchanger and is condensed into liquid and releases heat to produce high-temperature hot water. The liquid high-temperature working fluid is depressurized and expanded by the expansion valve Then return to the intermediate heat exchanger to absorb the evaporation heat again to complete a low-temperature cycle; through the reciprocating cycle, the effect of producing high-temperature hot water at low ambient temperature is achieved.


    The ultra-high temperature cascade hot water machine achieves a stable 90°C outlet under all working conditions from -30°C to 43°C (the highest 95°C outlet in the laboratory), which expands our company's application in the field of ultra-high temperature hot water. As a special heat pump, it is not only necessary to consider its special application scenarios, but also to ensure the reliability of its long-term operation. Omeron's ultra-high temperature cascade water heater is equipped with our mature jet enthalpy increase system to achieve -30℃ ultra-low temperature operation; the application of foaming high-efficiency tank heat exchangers ensures the unit water system at ultra-low ambient temperature Safety: With a speed-regulating fan, the initial system capacity can be reasonably unloaded according to the working status of the unit to ensure the stability of the unit’s 90℃ ultra-high temperature water output.


    The ultra-high-temperature cascade hot water machine has greatly promoted our company’s ability to occupy the ultra-high-temperature industrial hot water market. Under the general trend of coal-to-electricity, the ultra-high temperature effluent of the ultra-high Kang air energy heat pumps better occupy the market in the field of industrial hot water!


    The air-energy heat pump market has developed rapidly under the general trend of coal-to-electricity conversion. A large number of new laymen have transformed into the air energy industry, which has provided a greater impetus for the development of the air energy market. However, in the past, it was difficult for the outlet temperature of pure air energy equipment to exceed 85°C, which is the reason why air energy equipment has been relatively weak in the high-temperature hot water market. The high-temperature water demand of the factory is widely used in various slaughter plants, dairy plants, daily chemical plants, and washing plants; it has become the best choice for replacing northern heating boilers.
