LIQUID CIRCULATION HEATING SYSTEM |
| 摘要 |
<P>PROBLEM TO BE SOLVED: To provide a liquid circulation heating system using a refrigerant having a low global warming coefficient and high heating performance. <P>SOLUTION: This liquid circulation heating system 1A includes a heat pump 2 for producing a heated liquid and a heating radiator 3. The heat pump 2 has a heat pump circuit 20 for circulating the refrigerant to heat a liquid. The refrigerant contains tetrafluoropropene and difluoromethane as main components. According to this liquid circulation heating system 1A having such a configuration, a negative impact on global warming can be reduced. <P>COPYRIGHT: (C)2010,JPO&INPIT |
