Description
Technical Field

With the development of economy, the energy consumption of the air conditioning system is increasing in proportion to the total energy consumption of China. The green development is a great strategy for development in China, and the improvement of the energy efficiency level of the air conditioning system has great significance for energy conservation and emission reduction and carbon-to-carbon peak neutralization.
The traditional multi-connected air conditioning system mainly comprises two forms of air cooling and water cooling, and the air cooling multi-connected air conditioning system has the following problems: 1. the air density and specific heat capacity are small, the temperature rise is large, the condensation temperature is high, and the refrigeration energy efficiency is only 2.6-3.1. 2. The heat transfer coefficient of the air side of the unit is low, and the condensing coil and the unit are large in volume. 3. The unit is greatly influenced by the outside air temperature, and has low energy efficiency and poor reliability when running at high temperature in summer. The water-cooling multi-connected air conditioning system has the following problems: 1. the cooling water system is needed to be configured, and comprises a cooling tower, a cooling water pump, a filter, a scale remover and the like, the air conditioning system is complex, and the investment cost is high. 2. A special machine room is required, wasting valuable building space. 3. Refrigerant steam is condensed through cooling water temperature rise (namely sensible heat), the cooling water flow is large, and the energy consumption of a cooling water pump is high.
Under the design condition of the adopted lubricating oil return system, the existing multi-connected air conditioning system has the following defects: 1. lubricating oil can enter the heat exchanger along with the refrigerant, so that the heat exchange effect of the heat exchanger is affected. 2. In order to have sufficient lubrication in the compressor, it is necessary to bring the lubrication in the refrigeration system back to the compressor, requiring a complex oil return system and control mode. 3. When the multi-connected air conditioner runs under partial load (only part of indoor units are opened), the flow speed of the air return main pipe is low, lubricating oil in the evaporator is not enough to be brought back to the compressor, all the indoor units are required to be started at regular time, and the compressor runs at high frequency to return oil and circulate, so that energy waste is caused. 4. In order to ensure oil return, the muffler needs to have enough refrigerant flow rate, the diameter of the muffler must be limited, so that the muffler has high resistance, the air suction saturation evaporation temperature is low, and the energy efficiency of the unit is reduced.
