In the field of refrigeration and air conditioning, ordinary scroll compressors often encounter major challenges when operating at low evaporation temperatures. These challenges are manifested as increased suction specific volume, increased pressure ratio, and rapid increase in exhaust temperature. These conditions can lead to a sharp drop in compressor performance, insufficient heating capacity, and even operational difficulties. To address these issues, manufacturers have developed Enhanced Vapor Injection Compressors.
POSUNG’s Enhanced Vapor Injection Compressor has applied for a national invention patent,and the Intergated Four-way valve and the multi-function integrator have also applied for patents.
This system consists of three key components,including the Enhanced Vapor Injection Compressor,the integrated Four-way valve,and the multi-function integrator,which form the basis of the Enthalpy-enhancing system.
On this basis,the passenger car Enthalpy-enhancing Heat Pump System is formed.Parking air conditioning and engineering vehicle enthalpy-enhancing heat pump systems are currently used in thermal management systems to alleviate the problem of reduced vehicle battery charging and discharging capabilities at low ambient temperatures.
This innovative compressor design features an intermediate gas injection function that effectively alleviates the problems faced by traditional scroll compressors. By introducing a unique air injection mechanism, the enhanced steam injection compressor optimizes the workflow and improves performance even under low evaporation conditions. The air injection process not only stabilizes the pressure ratio, but also helps maintain a more constant exhaust temperature, thereby improving overall efficiency.
One of the outstanding benefits of the Enhanced Vapor Injection Compressor is its ability to significantly increase heating capacity. This is particularly beneficial in applications where stable temperatures need to be maintained, such as commercial refrigeration and HVAC systems. The compressor is designed to adapt to different operating requirements, making it a versatile solution for a wide range of applications.
In summary, the Enhanced Vapor Injection Compressor not only solves the key challenges faced by ordinary scroll compressors in low evaporation environments, but also has significant advantages and application potential. Its innovative design and operating efficiency make it a valuable asset in the pursuit of advanced refrigeration and air-conditioning solutions.
