Wind Energy

Working Principle • • A cool liquid refrigerant is pumped into evaporator, then absorbs thermal energy from the ambiance as a result of the temperature. In the process, the refrigerant change state and become vapor. • The gaseous refrigerant is then recompressed in the compressor. The pressure results in a temperature rise. • Then the condenser transports this thermal energy into heat storage and the refrigerant reverts to a liquid state. • The pressure is reduced again in the expansion valve and the cycle then start all over again.

By applying the heat pump system, the heat Q3 that user obtained is mainly from Q1 ambient air and little from Q2 electricity input, therefore heat pumps can greatly save electricity consumption for heating demand.

 Calculation condition: heating 10 tons water from 15 °C to 55 °C; 365 days per year for yearly cost calculation.  The energy price shown in the table is just for reference. Please refer to the local energy prices for specific cases.
