Simulation in transient regime of a heat pump with closed-loop and on-off control.

Author(s) : VARGAS J. V. C., PARISE J. A. R.

Type of article: Article, IJR article

Summary

The paper introduces a mathematical model for a heat pump with a variable-speed compressor, driven by a direct-current servomotor, operating either in closed loop by a power law control action or by the traditional on-off basis. The resulting differential and algebraic equations are integrated in time for a specified period of simulation in both designs. The results show that the closed-loop system presents significant savings in energy consumption when compared with the on-off system, under the same environmental conditions.
