Abstract

The invention discloses an air conditioner shell tube antifreezing method and an air conditioner using the air conditioner shell tube antifreezing method. The air conditioner shell tube antifreezing method includes the steps that the lowest temperature value of a shell tube evaporator is obtained in real time; whether the lowest temperature value meets the preset condition within the compressor starting preset time or not is judged; and when the lowest temperature value meets the preset condition, it is determined that the state is the water shortage state. According to the air conditioner shell tube antifreezing method, water shortage faults of the shell tube evaporator are accurately monitored in time by obtaining the lowest temperature value of the shell tube evaporator, and error protection is avoided. The invention further provides a computer readable storage medium.

Description

technical field [0001] The invention relates to the technical field of refrigeration equipment, in particular to an antifreeze method for an air conditioner shell tube, an air conditioner and a computer-readable storage medium. Background technique [0002] At present, air-cooled hot and cold water air conditioning units use dry shell tubes to start the cooling operation mode when the water pump is not turned on, which may easily cause water to freeze and crack the shell tubes. Specifically, in the absence of water flow, there is no flow heat exchange between the water side and the fluorine side of the shell tube of the unit, and the water fluorine heat exchange is poor. The evaporation temperature will become lower and lower during cooling operation. 1. The gap near the copper pipe begins to freeze, and the time is longer, the more the ice freezes, and the gap on the water side of the copper pipe will be filled with ice, causing the copper pipe to freeze or crack.
