Vapor Injection Compressor With Enhanced Enthalpy - China

The vapor injection compressor with enhanced enthalpy is a new type of compressor improved on the basis of the traditional scroll compressor.

Compared with traditional compressors, it has additional special vapor injection ports, refrigerant injection channels, and related valve bodies, partition plates or flanges.

During operation, the compressor absorbs the energy transferred from the evaporator through the suction port, and at the same time, introduces externally supplemented vapor from the vapor injection port.

The introduced vapor mixes with the refrigerant being compressed, transforming the original single-stage compression process into a quasi two-stage compression process, thereby improving the compression efficiency and reducing energy consumption.

The advantages of the vapor injection compressor with enhanced enthalpy are as follows:

• Improving Heating/Cooling Capacity: In a low-temperature environment, the vapor injection compressor with enhanced enthalpy can effectively increase the circulation volume and displacement of the refrigerant, thereby enhancing the heating output, enabling refrigeration and heating equipment such as air conditioners to maintain good performance in low-temperature environments.

• Increasing Energy Efficiency Ratio: The refrigerant in the injection loop has a heat exchange process with the refrigerant in the main loop before entering the compressor, absorbing the heat of the refrigerant in the main loop.

In the heating mode, it increases the heating capacity, and in the cooling mode, it is equivalent to increasing the cooling capacity of the evaporator, thus improving the energy efficiency ratio of the unit.

Application Fields:

• HVAC (Heating, Ventilation, and Air Conditioning) Field: Applying the vapor injection compressor with enhanced enthalpy in central air conditioners, household air conditioners and other equipment can effectively solve the problem of poor heating effect of ordinary air conditioners in low-temperature environments and improve the performance and energy efficiency of air conditioners.

• Air-source Heat Pump Field: The problem of heating efficiency of air-source heat pumps in low-temperature environments has always been a difficult issue in the industry.

The application of the vapor injection compressor with enhanced enthalpy significantly improves the heating capacity of air-source heat pumps in low-temperature environments, enabling them to be more widely applied in regions with different climatic conditions.

The vapor injection compressor with enhanced enthalpy developed by our company adopts the two-stage throttling with intermediate vapor injection technology, realizing the enthalpy enhancement effect through a flash evaporator for gas-liquid separation.

At medium and low pressures, it performs compression while injecting refrigerant for mixed cooling; at high pressures, it conducts normal compression to increase the compressor displacement, achieving the purpose of enhancing the heating capacity in low-temperature environments.
