Abstract (en)
[origin: EP3220075A1] A heat pump apparatus includes a refrigerant circuit to which a compressor (1), a condenser (3 or 5), an expander (4), an evaporator (5 or 3) are connected in a loop by a refrigerant tube. One of the condenser (3 or 5) and the evaporator (5 or 3) is a plate heat exchanger which performs heat exchange between a refrigerant and a liquid. The refrigerant which is filled in the refrigerant circuit contains R32 as a main component, which reduces refrigerant drift current inside the condenser (3 or 5) and pressure losses, and thereby increases energy-saving performances.
