Summary

Industrial Heat Pump (IHP) is widely leveraged to gain more economic benefits instead of boilers and electric heating. The process demands of high temperature above 80°C, such as chemical separation-rectification and lithium battery coating, are significantly increasing. Under such conditions, operating stability, system capability and efficiency are all technical difficulties. Therefore, to satisfy the industrial requirement and overcome the difficulties, this paper will provide an integrated cascade solution, including system design, component selection and control strategy, to obtain about 30kW heating capacity with 100°C ~ 120°C air stably. By method of simulation and prototyping test, enhanced vapor injection (EVI), heat recovery and valve cooling technology are well applied to guarantee high efficiency and system reliability, achieving an excellent applicability based on current component condition. In the meantime, not only ultra-temperature air function, space cooling function or medium cold source can be also acquired by evaporating side of MT circuit.
