Drop-in performance of the low-GWP alternative refrigerants R452B and R454B in an R410A liquid-to-water heat pump

Jaime Sieres et al.

Summary: This study investigates the performance of refrigerants R452B and R454B as drop-in replacements for R410A in a heat pump system, finding that the lower-GWP alternatives offer advantages in terms of higher discharge temperatures, lower heating and compression powers compared to R410A.

Influence of control strategy on seasonal coefficient of performance for a heat pump with low-temperature heat storage in the geographical conditions of Central Europe

Libor Kudela et al.

Summary: This paper presents a computational parametric study on increasing the Seasonal Coefficient of Performance (SCOP) for residential heat pumps, evaluating different approaches such as selection of low-temperature heat source, low-temperature heat storage, and control algorithms. The results show that potential SCOP increase of up to 5.19% can be achieved with simple software changes and connection to meteorological data prediction.

Domestic Retrofit Assessment of the Heat Pump System Considering the Impact of Heat Supply Temperature and Operating Mode of Control-A Case Study

Muhammad Abid et al.

Summary: This study investigates the performance assessment of a variable speed compressor-based air source heat pump system as a domestic retrofit technology in comparison to fossil fuel-based heating for a 1900s Mid terraced house. The assessment considered the impact of control mode and heat supply temperatures. The study found that using variable speed mode control in ASHP systems at different heat supply temperatures had limited research in the UK, with previous studies focusing on individual components and performance improvement.
