AI Technical Summary
Existing air conditioning waste heat recovery devices generally use a single heat exchange method, which leads to a decrease in heat absorption capacity after the circulating water temperature rises, making it unable to meet the demand for high-temperature hot water. In addition, the heat of the refrigerant is wasted, reducing the overall energy-saving benefits of the system.
A dual-tank circulation system is adopted. The temperature of the first tank is detected by a PLC controller. When the temperature exceeds the threshold, the pump of the second tank is started to introduce the medium from the second tank into the waste heat recovery unit. The medium from the second tank absorbs heat together with the medium from the first tank, realizing cascade heat exchange, increasing the upper limit of the medium temperature, meeting the demand for high-temperature hot water, and controlling the refrigerant temperature from rising.
It effectively increases the upper temperature limit of the heat exchange medium, meets the demand for high-temperature hot water, and avoids additional burden on the condenser and compressor, thereby improving the waste heat recovery rate and the overall energy-saving benefits of the system.
