Abstract This paper introduces a solar assisted heat pump hybrid water heating system, which could achieve
various functions, such as refrigeration, heating supply and water heating. Analytical and experimental studies
were carried out at the working mode of heat pump water heating and solar water heat pump for heating supply.
Based upon these results, a simulation study on the influence of ambient parameters, structure parameters and
operating parameters on the system performance was presented, and some suggestions on the system design and
operation control were raised to improve the performance.
