The main problem facing CO2 heat pump water heaters is to continuously improve efficiency and reduce costs, thereby improving their competitiveness with conventional heat pump water heaters. In order to improve efficiency, we need to rely on innovation in technology.
1) Development of expansion mechanism
Through theoretical analysis, the use of an expander to replace the throttle valve and recovery of the expansion work can greatly improve the performance of the transcritical CO2 cycle. Therefore, many research institutions at home and abroad are investing a lot of research and development efforts in research. The open literature reports involve expansion machine types including piston type, free piston type, scroll type, rolling rotor type, swing rotor type, sliding vane type, etc. Although A prototype has been developed, but many technical issues still need to be overcome.
2) Continuous improvement of CO2 compressor efficiency.
The compressor is a key component of the entire transcritical CO2 cycle system, and its efficiency directly affects the performance of the system. Many manufacturers and research institutions have improved the efficiency of CO2 compressors by improving the structure of CO2 compressors, improving processing accuracy, and improving the lubrication conditions of moving parts.
3) The heat exchange efficiency of the heat exchanger is continuously improved.
Through the analysis of the effective energy of the CO2 cycle system, it is found that in addition to the throttling loss, the loss of the heat exchanger also occupies a large part of the total loss, and even exceeds the throttling loss for a single-stage CO2 cycle. Heaters are critical to improving the performance of the CO2 cycle system.
4) The cold and heat of the CO2 heat pump water heater are used at the same time.
Theoretical research shows that the efficiency of the system can be significantly improved by using the cold and heat of the CO2 heat pump water heater at the same time. Therefore, it is more meaningful to develop a heat pump water heater that provides both hot water and cooling.
