How the eXergiemaschine-pro and eXergiemaschine-compact work
The eXergy machine works with a cooling circuit and must be combined with a heating buffer cylinder.
In the cylinder, the eXm ensures optimized temperature stratification - a higher flow to the consumer and a cool return flow to the heat source.
To do this, the eXm draws water from the center of the cylinder via two circuits. One circuit feeds the water to the machine's condenser, where it is heated before being fed into the upper part of the cylinder. The other circuit runs via the evaporator and then feeds the cooled water into the lower storage tank area.
Increase flow temperature
The eXm ensures that the required flow temperature is increased for heat sources that cannot provide this due to the system, e.g. for
- Heat pumps
- Heat recovery systems
- Thermal solar systems
- PVT collectors
- Cold local heating networks
This is achieved with a very high coefficient of performance and leads to an improvement in efficiency and a reduction in primary energy consumption in the overall system.
Reduce return temperature
For heat sources that rely on low return (system) temperatures for efficient operation, the eXm provides these independently of the user.
Typical heat sources are e.g.
- Classic district and local heating networks
- Condensing boilers
- Solar thermal systems
Extend switching cycles
Long running times and long pause times are typical operating modes for almost all heat generators. By ensuring stratification in the heating buffer, the eXm ensures large free heat capacities and therefore optimum operating conditions for
- Condensing boiler
- Heat pumps
- Volatile heat sources, such as solar thermal systems
For which applications does it make sense to use an eXm-pro or eXm-compact?
The eXergy machine is suitable for use wherever low return temperatures are required, flow temperatures need to be increased, switching cycles reduced, running times extended or where there are high circulation losses.
