Method, device and equipment for controlling space energy system, and storage medium

Abstract

The invention provides a method, device and equipment for controlling a space energy system, and a storage medium. The method comprises the steps of acquiring current wind speed information collectedby a wind speed sensor and flowing through an evaporator of the space energy system; acquiring a theoretical air suction superheat degree and an actual air suction superheat degree of the space energysystem; and adjusting the opening degree of an electronic expansion valve of the space energy system according to the difference between the theoretical air suction superheat degree and the actual air suction superheat degree and the current wind speed information. According to the method, device and equipment for controlling the space energy system, and the storage medium, the influence of windspeed is taken into consideration when the space energy system is adjusted, and certain compensation is carried out on the basis of adjusting the electronic expansion valve based on the difference between the actual air suction superheat degree and the theoretical air suction superheat degree, so that the electronic expansion valve is accurately adjusted, the real-time optimization of the space energy system is realized, the system fluctuation is reduced, the system operation stability is improved, and the system heating efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of household appliances, and in particular relates to a control method, device, equipment and storage medium of a space energy system. Background technique [0002] The space energy system is a combination of solar thermal utilization technology and heat pump technology in a mutually beneficial form. By consuming a small amount of electric energy, a large amount of low-grade energy (solar energy, air, etc.) in the surrounding environment is utilized, and compressed by the heat pump compressor. High grade energy. Used in the production of domestic hot water, it not only saves a lot of high-quality energy, but also has many advantages such as all-weather performance and weather resistance. It is not only suitable for household heating and hot water supply, but also suitable for central heating and hot water supply systems. New, most energy efficient and environmentally friendly water heater. [0003] The eff...
