Definitions

  • the invention relates to a fluid-based, closed pressure system with a first fluid circuit and a second fluid circuit, in particular a pressure system comprising a heating circuit and a refrigeration cycle of a building.
  • Heating and cooling devices are described with a heat pump, which have two fluid circuits.
  • the fluid circuits are coupled to each other in a specific manner, wherein in each of the fluid circuits, a separate expansion vessel is provided.
  • the invention has for its object to provide a liquid-based pressure system with a first fluid circuit and a second fluid circuit available, by means of which the installation and Maintenance costs can be reduced and the printing system can still be operated safely and efficiently.
  • a fluid-based, closed pressure system comprises a first fluid circuit with a first temperature control and a second fluid circuit with a second temperature control, wherein the first fluid circuit and the second fluid circuit are connected via a connecting container such that liquid of the first fluid circuit through the connecting container in the second Liquid circuit can flow in and liquid of the second liquid circuit can flow through the connecting container in the first liquid circuit, further wherein the first liquid circuit and the second liquid circuit are connected to a shared pressure-maintaining device.
  • the term temperature control means in the present case all means that make it possible to selectively influence the temperature of the liquid in the liquid circuit, so that in the first liquid circuit and in the second liquid circuit at least within a certain portion separately influence on the temperature the respective liquid can be taken.
  • a printing system according to the invention can be inexpensively installed and maintained by sharing a pressure holding device with the additional use of a connecting container, a liquid-based printing system with a first liquid circuit and a second liquid circuit, while still ensuring safe and efficient operation.
  • a container in the sense of this disclosure, all vessels, apparatus and devices are understood in which liquids "stored” and which liquids "transported” can be. These include pipe sections.
  • a container in particular those devices are to be understood that have a larger cross section compared to lines of a printing system.
  • first liquid circuit and the second liquid circuit are connected to a shared pressure-maintaining device
  • first liquid circuit and the second liquid circuit are connected to the shared pressure-maintaining device via a single (connection) line.
  • connection the liquid circuits are already connected together before the supply of the liquid, so that only a common liquid flow of the pressure holding device is supplied.
  • the pressure holding device therefore does not have to be adapted to two different fluid circuits and designed for different temperatures, pressures or other, differing parameters.
  • An inventive pressure system can be used particularly advantageously if the first fluid circuit is a heating circuit and the second fluid circuit is a refrigeration cycle.
  • the usual temperature ranges of such a heating circuit are between 25 ° C and 90 ° C, preferably between 25 ° C and 70 ° C.

  • an air conditioner with a refrigeration cycle and a heating system with a heating circuit are sometimes operated simultaneously. If, for example, the rooms of a building first have to be heated in the morning, the heating circuit is operated. The water of the heating circuit is then heated, which causes the water in the pipes to expand. If then, in particular due to strong solar radiation on a building side, individual rooms heat beyond the desired temperature, it may be necessary and desirable that using the refrigeration cycle and an associated air conditioning, the temperature in the building is partially actively lowered again. For this purpose, the temperature of the refrigeration cycle is reduced, which causes the volume of water in the refrigeration cycle to decrease.
  • This counter-rotating water volume trend between an expansion of the water in the heating circuit on the one hand and a reduction in the volume of water in the refrigeration cycle can be used by a pressure system according to the invention with a connecting container in order to achieve at least partial compensation.
  • the volume of a pressure holding device of a pressure system according to the invention can therefore be smaller than the sum of the volumes of two pressure holding devices that would be used in a separate heat cycle and refrigeration cycle.
  • the first fluid circuit has a higher temperature than the second fluid circuit, wherein the first fluid circuit is connected at a higher position to the connecting container than the second fluid circuit.
  • the connecting container of a pressure system essentially serves as a buffer memory, which should exploit any synergy effects between the first fluid circuit and the second fluid circuit, if such are present.
  • the volume of the connection container is preferably chosen smaller than the volume of the pressure-holding device.
  • the volume of the connection container is at most 50 percent of the volume of the expansion vessel. More preferably, the volume is at most 30 percent and more preferably at most 20 percent of the volume of the expansion vessel.
  • the volume of the connection container can also be designed with respect to the expansion volume of systems of a pressure system according to the invention. This can be in particular heating systems and / or refrigeration systems.
  • the volume of the connecting container is at most 50 percent of the maximum expansion volume of the system, more preferably at most 30 percent and particularly preferably at most 20 percent of the maximum expansion volume of the system. Decisive for this reference is the expansion volume of that system whose expansion volume is greatest when multiple systems are connected to the pressure system according to the invention, in particular a heating system and a refrigeration system.
  • the expansion volume of a heating system is defined as the difference between the maximum (permissible) water volume in the heating system during normal operation and the minimum (permissible) volume of water in the heating system during normal operation.

  • Particularly suitable as overflow elements are passage openings or transfer passages, bypass pipes or flow pipes firmly connected to the separating element.
  • Such overflow elements are intended in particular to counteract complete mixing by flows within the connection container. In this regard, it is preferred in particular if, owing to the formation of an overflow element, the influence of a flow taking place between the upper and the lower region on thermal layers which have already formed is as small as possible.
  • a plurality of separating elements can be arranged in the connecting container of a printing system according to the invention.
  • a connection is arranged above the upper separating element and a connection below the lower separating element

In this case results in a predominantly horizontal flow within the connecting container and thus a low mixing of the liquids in the vertical direction.
  • the sum of the cross-sectional areas of all the overflow elements is at most 10 times (and in an improved variant at most 5 times) the cross-sectional area of the connection cross-section to the first fluid circuit or to the second fluid circuit. It serves as a basis for determining the respective larger of the two connection cross-sections of the first fluid circuit and the second fluid circuit.

It is also possible to degas both circuits via only one degassing device, wherein such degassing preferably takes place via the heating circuit, since in a heating circuit temperature-dependent usually a stronger gas formation takes place within the fluid circuit.
