Description

technical field [0001] The invention relates to the technical field of compressor manufacturing, in particular to an air-conditioning system and a rotary compressor assembly thereof. Background technique [0002] It is pointed out in related technologies that the load of the air-conditioning system changes with the external conditions, especially multi-connected systems, such as a multi-connected system (one external unit with multiple indoor units), the load of the air-conditioning system changes with the opening and closing of the internal units. When the load of the air conditioning system is heavy, such as ultra-low temperature heating, due to the large specific volume of the refrigerant, the suction mass flow rate of the compressor is reduced, which not only leads to a significant reduction in the heating capacity of the compressor, but at the same time, due to the decrease in the mass flow rate, it is difficult to return oil , the heat taken away by the refrigerant is ...

AI Technical Summary

Problems solved by technology

When the load of the air conditioning system is heavy, such as ultra-low temperature heating, due to the large specific volume of the refrigerant, the suction mass flow rate of the compressor is reduced, which not only leads to a significant reduction in the heating capacity of the compressor, but at the same time, due to the decrease in the mass flow rate, it is difficult to return oil , the heat taken away by the refrigerant is reduced, which will easily lead to the wear of the compression mechanism of the compressor and the decrease of the reliability of the motor, and the energy efficiency of the system is low. System heating capacity and energy efficiency, and improved compression mechanism lubrication

[0003] However, in the cooling operation of intermediate refrigeration and other working conditions, the pressure ratio is small and the efficiency of single-stage compression is improved. If two-stage jet compression is also used, since two cylinders work at the same time, it will cause increased friction power consumption and increased specific cooling capacity. At the same time, it may cause overcompression of the refrigerant, resulting in a reduction in the energy efficiency of the two-stage jet compression

[0004] In addition, due to changes in external conditions, the demand for cooling capacity (or heat) is also different. When the cooling capacity demand is large, the refrigerant flow rate needs to be increased, and when the cooling capacity demand is small, the refrigerant flow rate is required to be reduced. Ordinary compressors It is difficult to take into account the two kinds of cooling capacity requirements. If the requirements of large cooling capacity are met, the flow rate will be too much, unnecessary work will be increased, and energy efficiency will be reduced when the demand for small cooling capacity is met; if the requirements of small cooling capacity and high efficiency are met, then When there is a large demand for cooling capacity, either it cannot provide sufficient refrigerant flow, or the operating frequency is extremely high, and the reliability of the compressor decreases
