Anti-freezing control method of water multi-split system, computer-readable storage medium, and air conditioner

Abstract

The invention provides an anti-freezing control method of a water multi-split system, a computer-readable storage medium, and an air conditioner. A current unit operation mode state is detected to determine whether an anti-freezing mode needs to be entered or not, if it is determined that the anti-freezing mode needs to be entered, a temperature range is distinguished by detecting ambient temperature, the water inlet temperature of the water inlet of the water side of a cold and hot water generator, the water outlet temperature of the water outlet of the water side of the cold and hot water generator, and the internal anti-freezing temperature of the water side of the hot and cold water generator are further detected, analyzing and calculation are conducted based on the water inlet temperature, the water outlet temperature, and the anti-freezing temperature, and then the unit is controlled to adjust related operating parameters. Through multi-conditional coupling control of the ambienttemperature, the water inlet temperature, the water outlet temperature, and the anti-freezing temperature, different from a traditional single condition judgment, misjudgment in an anti-freezing process can be effectively prevented, and a control idea giving consideration to accuracy, comfort, and energy saving is provided.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an antifreeze control method for a multi-water system, a computer-readable storage medium and an air conditioner. Background technique [0002] The functions of traditional household water machines are relatively old, the internal and external units cannot be linked, and only provide a fixed water temperature for cooling, which is less comfortable. Generally, refrigerants are used as refrigerants to achieve indoor cooling and heating effects, but this traditional The multi-connection unit has a characteristic, the temperature difference of the air outlet is relatively large, the operation process is unscientific, and the energy saving is poor, especially the bad usage habits are more likely to cause the above situation; to meet the user's indoor room air conditioning needs, the linkage between the indoor and outdoor units can be realized The water machine has stronger pr...

AI Technical Summary

Problems solved by technology

[0004] However, the water multi-system system has the problem of water system freezing when it is not turned on in winter. The main reason for this phenomenon is that the ambient temperature is lower than the freezing temperature of water when the unit is not running in winter

The emergence of the freezing problem not only seriously affects the user experience, but also creates certain hidden dangers in terms of system security
