Fin-and-tube heat exchangers are the mostly used heat exchangers for thermal energy
conversion with wide range of applications such as air conditioning, refrigeration …

This study reviewed heat recovery technologies and their application in residential buildings
in cold climates. The increasing efforts on reducing building energy use over the recent …

abstract The accretion of ice and frost on various infrastructure is ubiquitous in cold and
humid environments, causing economic losses amounting to billions of dollars every year …

Traditional solar collectors (SCs) cannot effectively use solar energy of varying intensity, and
air source heat pumps cannot supply heat steadily during defrosting conditions. Accordingly …

The effect of the frost growth and frost morphology on the performance of an air source heat
pump was investigated experimentally. The frost thickness, frost accumulation and the …

To improve the defrosting accuracy and the energy efficiency of the air-source heat pump
(ASHP) under frosting and defrosting conditions, a novel Temperature–Humidity–Time (T–H …

To better understand the frost growth characteristics of a tube-finned heat exchanger, a
novel frosting model was developed based on its frosting distribution characteristics. The …

When an air source heat pump (ASHP) unit operates for space heating at a frosting
environment, periodic defrosting is necessary to maintain a high system performance. To …

Flat tube heat exchangers are used in heat pump applications for energy-efficient heating
due to their compactness. If ambient air is used as a heat source, frost may form on the …

When an air source heat pump (ASHP) is operated at frosting conditions, controlling its
defrosting initiation is very important, which affects its operating efficiency and output heating …
