- An Empirical Study and Simulation on Performance Operation Heat Pump UsingSeawater Heat Source
- Abstract
- In this paper, the results of the performance operation of the heat pump
that uses seawater heat source in Jeju and based on the results, it was
presented a heat pump that is suitable for local seawater temperature through
analysis study of the combination heat pump system.
Seawater of Jeju, It has excellent characteristics as a heat source of the
heat pump and it is sufficient to take advantage of as a unit heat source of
Jeju thermal energy network so the experiment was conducted by installing
20RT unit scale of the heat pump.
Demonstration plant is located in Korea Institute of Energy Research Jeju
global research center. It was constituted by seawater heat exchanger, a heat
pump unit (compressor, condenser, evaporator, electronic expansion valve),
thermal storage tank and Fan Coil Unit and so on.
We went intensive demonstrated operation in the summer season(June ~
August) and winter season (November ~ February). It is results that cooling
COP indicates the range of about 2.95 to 3.60 and heating COP indicates the
range of about 2.9 to 3.55.
Based on the result, the analysis data and the experimental data was
confirmed to be within 10% error.
In addition to single heat pump, it was assumed the heat pump of three
forms (① Tandem Heat Pump, ② Cascade Heat Pump (410a-134a), ③
Cascade Heat Pump (134a-134a)). It analyzes the system by the combination
of the heat pump , and select the best heat pump unit in accordance with the
regional water heat source temperature and the heating temperature.
The analysis results, it is less than the heating temperature 50℃ withseawater temperature 10℃ or more, showing a good efficiency tandem heat
pump, cascade heat pump, if the temperature of the seawater is very low,
when the heating temperature is high, showed a relatively good efficiency.
