Title:
METHOD FOR ON-LINE DETECTION OF HEATING ENERGY EFFICIENCY RATIO AND HEATING CAPACITY OF AIR CONDITIONER
Document Type and Number:
WIPO Patent Application WO/2018/188430
Kind Code:
A1
Abstract:
A method for on-line detection of a heating energy efficiency ratio and a heating capacity of an air conditioner. The method comprises: during the operation of an air conditioner, acquiring a real-time compressor frequency, a real-time indoor temperature, a real-time outdoor temperature, a real-time internal unit rotation speed and a real-time external unit 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 indoor temperature, a typical core energy efficiency ratio and a typical relational expression; determining a real-time outdoor temperature energy efficiency ratio correction factor according to the real-time outdoor temperature and a rated outdoor temperature, determining a real-time internal unit rotation speed energy efficiency ratio correction factor according to the real-time internal unit rotation speed and a rated internal unit rotation speed, and determining a real-time external unit rotation speed energy efficiency ratio correction factor according to the real-time external unit rotation speed and a rated external unit rotation speed; and determining a real-time heating energy efficiency ratio according to the real-time core energy efficiency ratio and each energy efficiency ratio correction factor. By means of this method, a heating energy efficiency ratio and a heating capacity can be detected in real time under different operating conditions of an air conditioner.
