Abstract

The invention relates to a real time optimization control method for energy storage efficiency of a dual mode heat pump. The real time optimization control method for energy storage efficiency of a dual mode heat pump comprises an optimization model building step, a model solution step and an optimization control step. In the optimization model building step, the objective function of the optimization model is maximization of the instantaneous performance coefficient; and during the model solution step, the outlet fluid temperature of the cold and heat storage device is measured, the optimization model is solved by means of the genetic algorithm, and the optimal instantaneous performance coefficient and the optimal control parameters are obtained; and in the optimization control step, the heat pump energy storage system is controlled with the optimal control parameters. Compared with the prior art, the real time optimization control method for energy storage efficiency of a dual mode heat pump can set the cold and heat storage ratio according to the user demand of cooling and heating, and adjust the opening of the throttle valve, the flow velocity of the circulating fluid for cold and heat storage and the frequency of the compressor by means of the optimization model, therefore, the maximization of the total energy storage efficiency of a dual mode energy storage heat pump under the condition of a set cold and heat storage ratio can be realized.

Description

technical field [0001] The invention relates to an energy storage heat pump optimization control method, in particular to a dual-mode heat pump energy storage performance real-time optimization control method considering the ratio of cold storage and heat storage. Background technique [0002] A heat pump is a device that transfers heat from a low-temperature heat source to a high-temperature heat source. It usually extracts heat from the environment first, and then converts low-grade heat energy that cannot be directly used into high-grade heat energy that can be used through electricity. In the past, heat pumps were usually only used to meet cooling or heating needs. The dual-mode energy storage heat pump proposed by Blarke et al. in 2012 transfers the heat energy of the cold water tank to the hot water tank through electric power, and stores the energy of cooling and heating to meet the needs of intermittent hot water air conditioning in buildings and industries. It can ...
