Title:
ONLINE DETECTION METHOD FOR REFRIGERATION ENERGY EFFICIENCY RATIO AND REFRIGERATION CAPACITY OF AIR CONDITIONER
Document Type and Number:
WIPO Patent Application WO/2018/188520
Kind Code:
A1
Abstract:
An online detection method for a refrigeration energy efficiency ratio and a refrigeration capacity of an air conditioner. The online detection method for a refrigeration energy efficiency ratio comprises: during the operational process of an air conditioner, acquiring a real-time compressor frequency, a real-time indoor temperature, a real-time outdoor temperature, a real-time inner machine rotation speed and a real-time outer machine rotation speed; determining a real-time core energy efficiency ratio corresponding to the real-time compressor frequency and the real-time indoor temperature according to a typical compressor frequency, a typical outdoor temperature, a typical core energy efficiency ratio and a typical relational expression; determining a real-time indoor temperature energy efficiency ratio correction factor according to the real-time indoor temperature and a rated indoor temperature, determining a real-time inner machine rotation speed energy efficiency ratio correction factor according to the real-time inner machine rotation speed and a rated inner machine rotation speed, and determining a real-time outer machine rotation speed energy efficiency ratio correction factor according to the real-time outer machine rotation speed and a rated outer machine rotation speed; and determining a real-time refrigeration energy efficiency ratio according to the real-time core energy efficiency ratio and each energy efficiency ratio correction factor. Thus, the real-time detection of a refrigeration energy efficiency ratio and a refrigeration capacity under different operational working conditions of an air conditioner can be achieved.
