A modelling study on the frosting characteristics of a novel dual-fan outdoor coil in an Air Source Heat Pump unit
( Elsevier , 2023 , Article)Uneven frosting along the airflow direction in a traditional outdoor coil in air source heat pumps (ASHPs) was inevitable due to a fixed one-way outdoor airflow direction, causing a rapid deterioration in heating performances ... -
A novel time-current-temperature difference (T-I-T) defrosting control method for air source heat pump based on outdoor fan operation characteristics in space heating
( Elsevier , 2025 , Article)In space heating, air source heat pumps (ASHPs) always encounter mal-defrosting incidents, resulting in significant energy waste. To improve the defrosting accuracy of ASHP, this paper proposes a novel Time-Current-Temperature ... -
Determination of the defrosting duration ratio for defrosting performance evaluation of air source heat pump
( Elsevier , 2024 , Article)Defrosting performance evaluation is an important aspect for pre-delivery inspection of air source heat pumps (ASHPs). According to GB/T 25127-2020 and ANSI/AHRI 550/590–2023, defrosting duration ratio (α) should not exceed ... -
A prediction model of the optimal defrosting initiating time for the air source heat pumps with different configurations and operations
( Elsevier , 2025 , Article)Frosting is a critical challenge that affects the energy efficiency of air source heat pumps (ASHPs). Defrosting periodically is the most widely used method to solve this problem. However, the rate of frosting varies ... -
A novel variable speed ASHP frosting suppression operation method based on the frosting suppression performance map
( Elsevier , 2023 , Article)For variable speed (VS) space heating air source heat pump (ASHP) unit, its different operation speed combinations may significantly affect the frosting suppression and heating performances. However, currently there is no ... -
Experimental study on the effects of melted frost icing on the operating performances of air source heat pump
( Elsevier , 2024 , Article)Defrosting operation is always used to solve its frosting problem at a high humidity environment for air source heat pump units (ASHPs), and at the end of defrosting operation, the residual melted frost may exist on the ... -
An experimental study on the defrosting performances of an ASHP having a novel dual-fan outdoor coil under different levels of frosting evenness along airflow direction
( Elsevier , 2024 , Article)Uneven frosting along the airflow direction is a common phenomenon that can accelerate deteriorating the heating efficiency of ASHP units under frosting conditions. To effectively alleviate this uneven frosting phenomenon, ... -
An optimal control strategy for ASHP units with a novel dual-fan outdoor coil for evener frosting along airflow direction based on GRNN modelling
( Elsevier , 2023 , Article)It was demonstrated in previous related experimental and modelling studies that an ASHP unit having a novel dual-fan outdoor coil (ASHP / DFOC) can help achieve evener frosting along airflow direction in the outdoor coil, ... -
A novel coefficient of frosting suppression based on the real-time operating characteristics of air source heat pumps
( Elsevier , 2023 , Article)It has been known that for space heating ASHPs, their different configurations and operation may influence their frosting performances. However, there has been no comprehensive coefficient that can be conveniently and ... -
A method for sizing air source heat pump considering the joint effect of outdoor air temperature and relative humidity
( Elsevier , 2023 , Article)When operated in a highly humid environment, frost may accumulate on the surface of the outdoor coil in air source heat pump units (ASHPs), leading to a reduction in its output heating capacity. Currently, the existing ... -
Developing a novel control strategy for frosting suppression based on condensing-frosting performance maps for variable speed air source heat pumps
( Elsevier , 2023 , Article)Effective frosting suppression was crucial to further wider applications of air source heat pumps (ASHPs). However, existing frosting suppression measures may not be fully implementable in practice due to various reasons ... -
Space heating performance analysis of air source heat pump integrated with image gray recognition-based defrosting controller
( Elsevier , 2024 , Article)In practice, owing to the unreasonable defrosting initiating method of air source heat pumps (ASHPs), mal–defrost occurs frequently, further leading to the increase of building heating energy consumption. In recent years, ... -
