Operation control of a CO2 heat pump for application in existing heating systems.
Author(s) : ENKEMANN T., KRUSE H.
Summary
The natural fluid CO2 is investigated as the refrigerant in a transcritical heat pump cycle. Controlling the heating power and the high side pressure, which is a new aspect of a transcritical cycle in comparison to the usual vapour compression cycles, is investigated with respect to the specific demands. Solutions concerning control of heating power and high side pressure are compared and evaluated. Application limits are investigated. A concept for the operation control is proposed.
