Abstract
An approach to the study of heat exchange processes of the heat pump condenser circuit has been proposed. A mathematical model of the heat exchange process of the heat pump condenser circuit and the consumption line circuit has been constructed. The mathematical model is based on the equations of material and energy balances of the working fluid of the heat pump. Transfer function by the temperature of the freon in the condenser due to the regulating action of the temperature of the liquid of the consumption line has been constructed as well as the transfer function by the temperature in the consumption line due to the control action of the working fluid in the heat pump circuit. The transient responses for the freon temperature in the condenser and the temperature of the consumption line liquid have been obtained, respectively, and their research has been carried out with the help of simulation modeling. The transient responses of the studied circuits have been built. The results and graphs of transient processes and dynamic responses of the object have been given. It has been established that at lower consumption of liquid in the line of consumption the constant of time of transient process is of inertial character, and, therefore, in this case, the investigated conditions necessitate the increase of expenditures in the line of consumption, or in performance control of a compressor.
