Air-conditioning unit multi-stage refrigeration method, device, computer equipment and storage medium

Abstract

The present application relates to a multi-stage refrigeration method, device, computer equipment and storage medium of the above-mentioned air-conditioning unit. Set the third temperature, start the fixed-frequency unit and the variable-frequency unit asynchronously, give priority to the fixed-frequency unit for rapid cooling, and delay the start-up of the variable-frequency unit to avoid excessive temperature changes at the air outlet due to the sudden increase in cooling capacity; The difference between the temperature of the air supply outlet and the preset temperature, adjust the working frequency of the frequency conversion unit, adjust the cooling capacity of the air conditioning unit again, further optimize the temperature of the air supply outlet, and avoid the sudden change in the temperature of the air supply outlet to the environment (surrounding equipment or people). Influence, effectively reduce the variation range of air supply temperature.

Description

technical field [0001] The present application relates to the technical field of refrigeration control, in particular to a multi-stage refrigeration method, device, computer equipment and storage medium for an air conditioner unit. Background technique [0002] With the development of science and technology, air conditioning units have been applied to more and more scenarios, bringing convenience to people. In some specific scenarios, the air conditioning unit is required to be able to rapidly cool down in a short period of time, which puts forward higher requirements for the control of the air conditioning unit. [0003] Take the aircraft ground air-conditioning unit as an example, the aircraft ground air-conditioning unit refers to the air-conditioning unit that provides air-conditioning for aircraft parked on the apron ground. Due to the short parking time of the aircraft on the apron, the ground air conditioner of the aircraft must cool the fresh air at 35°C to 2°C and ...

Problems solved by technology

[0004] Although the above-mentioned multi-stage refrigeration method can achieve rapid refrigeration in a short period of time, adjusting the refrigeration capacity by shutting down and unloading will cause large fluctuations in the temperature of the supply air, and temperature fluctuations will affect the life of precision instruments in the aircraft cabin and the flight time. People's comfort is affected
