Raw-water source heat pump for a vertical water treatment building

A key review of wastewater source heat pump (WWSHP) systems

“…In [40], TRNSYS software was used to dynamically simulate a WWSHP with a thermal storage tank which is used to meet cooling and heating needs of a vertical water treatment building. As illustrated in Fig.…”

“…Schematic illustration of the raw-water source heat pump with a thermal storage tank (modified from[40]). I.…”

Experimental and numerical study of a water-to-water heat pump working with CO2

“…The overall COPs when increasing the evaporator water inlet temperature from 10 °C to 25 °C and the gas cooler water inlet temperature from 10 °C to 40 °C in order to produce hot water at 60 °C, are 3.4866 for C1&C2 and 3.5217 for C3. When the evaporator water inlet temperature is 30 °C, while varying the gas cooler water inlet temperature [158]…”
