Abstract

The invention discloses a method for determining an optimal floor heating operation condition of an air source heat pump based on energy conservation. All conventional methods have the problem that the energy cannot be saved enough and is wasted. The method considers the influence of the environmental temperature, the water supply temperature and the circulating water mass flux on a system, and comprises the steps of creating a heat balance model of floor heating, creating an energy efficiency ratio and power consumption model of the heat pump, creating an energy consumption model equation of floor heating water circulation, creating a total optimization model, and optimizing by the models to obtain optimal control parameters for enabling the system to run at an optimal working point. According to the method, the running energy consumption of the system can be reduced, so that the purposes of reducing the running cost, saving energy and reducing emission are achieved.

Description

technical field [0001] The invention belongs to the technical field of control, and relates to a method for determining the best operating condition of an air source heat pump and floor heating based on energy saving. Background technique [0002] With the improvement of people's living standards, the demand for household floor heating is increasing, and since household floor heating requires more energy consumption, it is very important to reduce energy consumption and maintain a certain degree of comfort. With the shortage of energy and the implementation of national energy conservation and emission reduction policies, the development and utilization of renewable energy is an important way to save energy and reduce consumption. Air source heat pumps can absorb heat from the air, and use one part of electric energy to produce more heat, so they are getting more and more applications. The application of air source heat pumps in the field of floor heating is not only benefic...
