Running control method, device, air conditioner and computer readable storage medium

Abstract

The invention provides a running control method, a device, an air conditioner and a computer readable storage medium. The running control method comprises the steps that after the running time of theheating mode reaches the preset time, the temperature difference between the middle temperature and the outlet temperature of a second type indoor unit is determined and recorded as the supercooled degree temperature difference; and the size relationship between the supercooled degree temperature difference and the preset temperature difference is compared according to the preset period; and the opening-closing degree of an electronic expansion valve of the second type indoor unit is adjusted according to the size relationship. Through the technical scheme of the running control method, a refrigerant in the air conditioner can normally flow, the problem that the refrigerant accumulates in the second type indoor unit is solved, accuracy and reliability of control of the opening-closing degree of the electronic expansion valve are improved, the situation that the opening-closing degree of the electronic expansion valve is excessively large or small is effectively reduced, the stability of running of the air conditioner is further improved, the heating energy efficiency of the air conditioner is improved, and improving of the user experience is facilitated.

Description

technical field [0001] The present invention relates to the technical field of air conditioning control, and in particular, to an operation control method, an operation control device, an air conditioner and a computer-readable storage medium. Background technique [0002] The air conditioner can be driven by one outdoor unit to run multiple indoor units, which is called one-to-many air conditioner, which not only saves the installation space of the outdoor unit, but also has the advantages of simple system installation, compact structure and comfort, and independent adjustment and operation of each room. , can meet the different temperature control needs of each room. [0003] In the related art, the refrigerant distribution of one-to-many air conditioners is related to the stability of the operation of the entire system. Each indoor unit is provided with a corresponding electronic expansion valve to control the circulation of the refrigerant, and adjust the opening and clo...

AI Technical Summary

Problems solved by technology

[0004] However, during the operation of one-to-multiple air conditioners, the electronic expansion valve corresponding to the unopened internal unit needs to maintain a certain opening and closing degree. The opening and closing degree of the shutdown will affect the heating performance of the internal unit when it is turned on. A large amount of refrigerant is stored in the unopened internal unit, resulting in insufficient refrigerant in the system; when the opening and closing degree is too large, the heat is unloaded through the unopened internal unit, resulting in waste of heat
