CO2 3-way Valves
A 3-way CO2 valve for heat reclaim in a CO2 system is designed to redirect the flow of CO2 between two different circuits in order to recover heat from one circuit and transfer it to another. This process is also known as heat recovery.
The valve typically consists of three ports: an inlet port, an outlet port, and a third port that can be connected to either the heat source or the heat sink circuit. The valve is controlled by an actuator that moves the mechanism inshttps://www.youtube.com/@RefrigerationMentorde the valve body to direct the flow of CO2.
During the heat reclaim process, the valve is positioned so that the CO2 flow is directed through the heat source circuit. This allows the CO2 to absorb heat from the heat source, which could be a refrigeration system or a heat pump. The CO2 then flows through the valve and is directed to the heat sink circuit, where it transfers the heat to the system being heated, such as a hot water supply, in floor heat, slab heat or to a air handling unit to provide space heat.
The direction of flow can be reversed by the actuator to allow for heating or cooling as required. In this way, the 3-way CO2 valve plays an important role in improving the energy efficiency of a CO2 system by recovering waste heat and reducing the overall energy consumption of the system.
