Abstract:With the development of seawater source heat pump system, the simulation of the heat pump has being the focus. For simulating one kind of two-stage centrifugal vapor-compression water source heat pump's energy consumption and COP and studying the running performance, this paper utilizes the mass and energy balance to establish the steady thermodynamic model, adopts the arithmetic in which the sequential modular method and successive substitution method are combined together, designs and identifies the structure's parameters and then validates the simulation by the sample data. The main work is to simulate the heat pump's performance parameters in full load and part load, besides to simulate the COP of the kind of heat pump with various capacity. Now this kind of heat pump has been successfully used in abroad, so the simulation for the heat pump unit is of significance for the alike projects in future.
