6-1-1. Principles of Heat Pump
Heat pump maintains the temperature higher than the ambient temperature. In order to achieve
this, it requires insulated space, refrigerant R134a for absorbing heat, and a circulation circuit for
controlling phase of the refrigerant (compressor, condenser, evaporator, etc.).
