The invention relates to a metro air conditioning unit temperature control method and device and a readable storage medium, and the metro air conditioning unit temperature control method comprises the steps that the environment temperature outside a metro is obtained; according to the environment temperature, first operation time of the air conditioning unit in a refrigeration mode is obtained; if the first operation time is smaller than a first time threshold value, the operation mode of the air conditioning unit is adjusted to be a cooling capacity balance mode; second operation time of the air conditioning unit in the cooling capacity balance mode is detected; and if the second operation time is larger than or equal to a second time threshold value, the operation mode of the air conditioning unit is adjusted to be a refrigeration mode. According to the control method and the control device, the second operation time of the air conditioning unit in the cooling capacity balance mode is controlled, so that the problems of no cooling capacity output or cooling capacity output reduction and keeping of the temperature in the vehicle stable when the compressor needs to continuously operate due to the shortest operation time are solved, and the temperature in the vehicle is stable.
Description
technical field [0001] The present application relates to the technical field of frequency conversion air conditioners for trains, in particular to a temperature control method, device, system, computer equipment, and computer-readable storage medium for subway air-conditioning units. Background technique [0002] In the transition season, the actual cooling load inside the car is small, and the demand for cooling capacity is small. At this time, the outdoor temperature is not high, the condensation temperature is low, and the energy efficiency ratio of the air conditioning unit is high, and the cooling capacity is large. Among them, the frequency conversion of the air-conditioning unit is: limited by the minimum operating frequency of the compressor; the fixed frequency of the air-conditioning unit is: hot gas bypass control, the unit has a minimum cooling capacity limit, and the cooling capacity in the transition season is much greater than the actual demand, causing the te...
