High humidity environment heating -- high efficiency defrosting flexible air source heat pump module unit

High efficiency defrosting flexible air source heat pump unit is another masterpiece of cooperation with the research and development team of Tsinghua University. Its technical features are efficient defrosting in high humidity and temperature environment and continuous and stable heating. It is suitable for refrigeration and heating in the south wet and cold areas, and helps to achieve the "30.60" national strategic goal of dual carbon.

This product uses antifreeze as the heat transfer medium of the heat pump system. It makes rational use of the coordinated distribution of the heat produced at the user side and the energy side, and takes into account the defrosting and heating needs of the air source heat pump. It can still operate continuously and stably during heavy frost, which can meet the efficient heating needs of most regions in China (especially in the Yangtze River basin). It is the preferred solution for clean energy and comfortable heating of civil and commercial buildings.

Product characteristics of Kcalin air energy heat pump unit

1) Patent system

The patented thermal system and its control method designed according to the principle of time-space heat allocation not only ensure the continuous and stable heating demand of users, but also ensure the efficient defrosting of the unit after frosting.

2) Accurate defrosting

Real time measurement of the change of heat intake at the air source side during the operation of the unit, directly judging the degree of frosting according to the decay of heat intake, greatly reducing the probability of false defrosting; In addition, measure the change of defrosting heat of the unit in real time, and stop defrosting in time to avoid additional heat loss.

3) Reliable operation

During defrosting, the heat allocation will not affect the stable and continuous operation of the refrigerant system. Compared with the traditional reverse defrosting or hot gas bypass defrosting, the suction and discharge pressure of the compressor will not change, which ensures the continuous and stable operation of the compressor and greatly improves the reliability and operating life of the unit.

4) High efficiency and energy saving

The energy saving efficiency ratio in heating season is higher than the limit value of the latest energy efficiency standard in China; (In normal heating, the nominal energy efficiency ratio is 2.63; the energy efficiency ratio in heating season is 3.30, which conforms to the limit requirements of the latest version of JB/T 14077-2021 Air Source Heat Pump Hot Water Unit for Floor Heating). In addition, when the unit works in frost prone areas, the energy consumption for winter operation can be saved by more than 20%.

5) Wide applicability

Operating temperature range of this series of units: - 20~43 ℃; The unit is equipped with multiple protection controls, and can operate safely and reliably above - 20 ℃ outdoor ambient temperature; It can be widely used in industrial and commercial refrigeration and heating projects in the Yangtze River and Yellow River basins and most areas of North China.

6) Low noise

The STS time-space division multi fan strategy is adopted, so the overall noise of the unit can be well controlled. The noise is less than 57dB (A), and the high and low pressure impact sound generated by reversing is also eliminated.
