Performance improvement of vapor-injection heat pump system by employing PVT collector/evaporator for residential heating in cold climate region

Jian Yao et al.

Summary: This study introduces a vapor-injection heat pump system with a PVT collector/evaporator to improve efficiency under extremely low temperature conditions. The system can operate off-grid at -10 degrees Celsius and 500 W/m2 solar irradiation, showing excellent performance in both electrical and thermal efficiency. Additionally, a hybrid control method has been proposed to enhance system performance, with a significantly lower levelized cost of heat compared to electric heating systems.

The difference between vapor injection cycle with fl ash tank and intermediate heat exchanger for air source heat pump: An experimental and theoretical study

Jijin Wang et al.

Summary: Vapor injection is an important technique in air source heat pumps, with flash-tank based solutions showing better performance than intermediate heat exchanger based ones. Injected vapor improves mass flow rate and distribution of working fluid, and moderate injected vapor entropy contributes to performance improvement of vapor-injection based ASHPs.

Impact of micro-grooves in scroll wrap tips on the performance of a trans-critical CO2 scroll compressor

Siyu Zheng et al.

Summary: Radial leakage is considered a key factor limiting the aero-thermodynamic performance of scroll compressors. This study proposed a passive flow control approach using micro-grooves in the scroll wrap tip to reduce radial leakage, resulting in improved volumetric and isentropic efficiency. The geometric parameters of the micro-grooves directly affect the flow control performance, with increasing groove numbers and partitions effectively decreasing leakage, while leakage initially decreases and then increases with groove depth.
