Abstract

The invention relates to the technical field of air conditioning, in particular to a heating control method and control system for an air conditioner. The invention aims to solve the problem of low heating efficiency existing in the existing inverter air conditioner. For this purpose, the heating control method of the present invention includes: in the heating mode, obtaining the outdoor ambient temperature and the operating frequency of the compressor; calculating the theoretical temperature of the supercooled pipe section based on the outdoor ambient temperature; and theoretical temperature, calculate the operating opening of the regulating valve; adjust the opening of the regulating valve to the operating opening. The above heating control method enables the air conditioner to control the opening of the regulating valve to a better opening degree based on the current operating state of the air conditioner and the outdoor environmental conditions when the air conditioner is heating, so as to accurately control the subcooling degree of the air conditioning system, so that the air conditioner The heating effect is the best, and the heating energy efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a heating control method and control system for an air conditioner. Background technique [0002] Traditional inverter air conditioners only assess cooling energy efficiency and power, and use cooling energy efficiency as the energy efficiency grade evaluation standard, but have no requirements for heating power and capacity. Therefore, when developing inverter air conditioners, R&D personnel generally use the best cooling energy efficiency as the design principle. [0003] However, with the promulgation and implementation of the new national energy efficiency standards, the cooling, heating power and energy efficiency of the inverter air conditioner are included in the assessment scope, and the heating energy efficiency has a great impact on the overall energy efficiency of the air conditioner, so reduce the heating power of the inverter air conditioner, improve Its hea...
