Integrated crew for heating and dehumidification of air-source heat pump for tobacco curing. [PDF]
Due to the low heating efficiency of heat pumps for tobacco curing caused by the low external environment in high-altitude areas, the high energy consumption and unstable heating is easy to occur. According to the heating model of flue-cured tobacco needed, the integrated crew of the air-source HP heating/dehumidification equipment was designed ...

THE SCOP OF AN AIR SOURCE HEAT PUMP: COMPARISON BETWEEN ON-OFF AND INVERTER HEAT PUMP
The paper investigates the seasonal performance of electric air-to-water heat pump comparing an on-off heat pump with an inverter-driven variable speed compressor. Reference is made to a heat pump for domestic space heating installed in Bologna, and the bin-method proposed by UNI/TS 11300-4 is employed in order to investigate the effect of external ...
