The invention relates to a refrigerating system, a refrigerating method and an air conditioning unit. The system comprises multiple stages of mutually independent refrigerating subsystems, a detectionmodule, and a controller; the first stage of refrigerating subsystem comprises a first evaporator and a second evaporator which are connected in parallel; the detection module is used for detecting the air inlet temperature of the first stage of refrigeration subsystem; and the controller is used for controlling the working state of each stage of refrigeration subsystem according to the air inlettemperature, so that the refrigeration system maintains low air outlet temperature and low evaporation temperature in a high-temperature environment. According to the refrigerating system, the refrigerating method and the air conditioning unit, the evaporator of the first stage of refrigeration subsystem is set to be the first evaporator and the second evaporator which are connected in parallel,the air inlet temperature of the first stage of refrigeration subsystem is detected, the working state of each stage of refrigeration subsystem is controlled according to the air inlet temperature, therefore, the refrigerating system can maintain the low air outlet temperature and the low evaporation temperature in the high-temperature environment, the reliability is met, meanwhile, the energy efficiency of the air conditioning unit is improved, and energy-saving and efficient operation is achieved.
Description
technical field [0001] The invention relates to the technical field of air-conditioning units, in particular to a refrigeration system, a refrigeration method and an air-conditioning unit. Background technique [0002] With the continuous improvement of people's living standards, people's pursuit of air-conditioning comfort is getting higher and higher, and fresh air units are more and more used in air-conditioning projects. For high-temperature and hot regions such as the Middle East, the enthalpy of the incoming air is high, and the cooling load is large. Single-stage evaporation cannot meet the demand for cooling with a large enthalpy difference, so multi-stage evaporation is often used. However, due to the high enthalpy value of the inlet air of the first-stage evaporator, the evaporation temperature is high, and the reliability of the compressor decreases in multi-stage evaporation; when the inlet air temperature is low, it is prone to freezing and low-pressure protecti...
