377,650 BTU/Week x 52 Weeks/Year = 19,637,800 BTU/year or 5,755 kWh. Assuming that the natural gas costs $ 10/MMBTU (1 MMBTU = 1000000 BTU) and electricity costs 0.092 per kWh, the gas costs would be $ 196.37 while electric costs would be $ 529.46. Clearly, electric heat

Journal:Energy / Publication Year:2019 / Source:2019 v Traditional seawater-source heat pump (SWHP) needs to set water intake and titanium plate heat exchanger which result in high initial investment and large work quantity. A new type of SWHP was recommended, which use capillaries made by PPR (polypropylene random) submerged in seawater as the front-end heat exchanger.
· Web viewTo recover heat energy from effect 1, the steam evaporated there is introduced to effect 2, where it condenses on a second heat transfer surface, typically 2°C or more cooler than the steam from effect 1, evaporating a near equal mass of saline water to that evaporated in effect 1.
