It starts with introducing the fundamentals of heat pumps, including explaining the refrigerant cycle, coefficient of performance, and performance factor. Then review the application of different types of heat pumps, refrigerants, and heat exchangers from the literature. For modeling the heat pump, two methods are used in the work. The compressor and the expansion valve are using the first method which is modeled by the datasheet and the measurement data; the condenser and the evaporator are utilizing another method for modeling which is by the MATLAB tool parameter estimator. The thesis has explained the detailed method of modeling the heat pump. After completing the model, it has been run and validated by the measurement data from the prototype. The model can operate properly and the properties of the simulation model are reasonable. But for validating the model which means compared to the measurement data from the prototype, there are still some flaws or errors, especially for the evaporator model. They will be discussed in the work. Overall, the thesis still provides a promising method for developing the simulation model of a heat pump.}, language = {en} }
