Solar assisted air source heat pump shows great potential as a promising energy-saving
heating technology, which integrates solar collector and air source heat pump. It is widely …

This paper reviews the results of frosting, defrosting and frost management research that
have been reported over the past fifty years. The literature can be split into three categories …

Thermal energy storage and recovery in a double-pipe latent heat storage (LHS) system
with variable wave-length wavy channels were examined. The presence of wavy channels …

For a space heating air source heat pump (ASHP) unit, when its outdoor coil surface
temperature is below both the air dew point temperature and the freezing point of water, frost …

This paper concerns the optimum design of double elliptical latent heat storage units during
the charging process using three-dimensional numerical simulation. Water and RT35 are …

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 …

A novel wavy channels triple-tube latent heat storage (LHS) unit accompanied by variable
wavelength is examined in charging/discharging mechanisms. The LHS triple-tube LHS unit …

The condensation and freezing processes of fin-and-tube heat exchangers with a bare
surface and coated with a superhydrophobic substance were experimentally studied for …

Frost formation on a horizontal flat copper surface was experimentally investigated using
microscopic observations. The experiments were carried out on− 20 to 0° C copper surfaces …

This study is concerned with a hot gas (refrigerant) bypass method to retard the formation
and propagation of frost in an air-source heat pump. The feasibility of the hot gas bypass …
