Résumé

A running model of the heat pump that operates at the low load status (operating load is not more than half of system's designing capacity) is presented in this paper. A full load intermittent running model will result in that the system starts and stops frequently and consumes a large amount of extra energy, thus partial load intermittent running model will be introduced in this paper. The partial operating load of the system at the low load status is calculated based on optimization theory, in which energy consumed function of the system and operating load are regarded as the object function and optimized parameter, respectively. The result shows that there is an optimum running load making the system running in the lowest energy consuming and can greatly improve the system's performance in the case of a small heat capacity and a great heat output.
