Heating and cooling are responsible for considerable portion of final energy consumption in
the world especially in the residential sector. In order to decrement the pollutants and energy …

Solar energy is considered a clean and promising source of energy. The vapor compression
heat pump technology is identified as the most suitable and efficient method to fulfill both …

Previously, the conventional fin-and-tube heat exchanger is usually chosen as the
evaporator in the air source heat pump. Recently, with the higher heat transfer efficiency, the …

Traditional dual-source heat pumps are generally composed of separated flat PV
evaporators and finned-tube evaporators connected in series or parallel, occupying too …

In order to improve the specific moisture extraction rate (SMER) of the closed-cycle heat
pump drying (CHPD) system applied to paddy drying, three types (Heating evaporator outlet …

Dislike the electrical performance, the heat collection capacity is always disappointing in the
photovoltaic evaporators. It is always handled by adding additional finned-tube evaporators …

In the present study, a dynamic model of evaporators in a CO 2 solar assisted heat pump is
presented and experimentally validated. The evaporators are PV-T (photovoltaic-thermal) …

Microfluidic devices are composed of microchannels with a diameter ranging from ten to a
few hundred micrometers. Thus, quite a small (10− 9–10− 18 l) amount of liquid can be …

The direct expansion solar heat pump (DX-SHP) is a competent and sustainable option for
domestic heating and drying applications. The solar collector-evaporator is a vital …

Traditional flat PV heat pumps has low irradiation density, large PV area, and the PV
evaporators are always fixed, causing large area occupation and lots of irradiation missing …
