Description
[0001] The present invention relates to a heating or cooling system
with a distributer and/or a collector for the distribution of the
heating or cooling medium on the respective heating or cooling
surfaces according to the preamble of claim 1.
[0002] Often, such heating or cooling systems feature several
heating or cooling circuits whereby valves are used to pre-set the
flow of the heating or cooling medium. Additionally, in the
respective heating or cooling circuits, thermostat valves are
provided (for the regulation of the flow of the heating or cooling
medium dependent on the room temperature) and/or valves which
regulate the return temperature. All of these valve configurations
are ultimately resulting in a variety of different flow patterns of
the heating or cooling medium in the various heating or cooling
circuits. That is because, dependent on the respective valve
opening, different levels of flow resistance are opposing the
pumped heating or cooling medium.
[0003] Furthermore, such heating or cooling systems often feature
additional heat or cold exchangers in the form of heating or
cooling elements with additional room thermostat valves, where the
flow of the heating or cooling medium in turn is designed
differently from the flow through the heating or cooling
circuits.
[0004] A heating or cooling system according to the preamble of
claim 1 is shown in DE 196 50 892 C2. The various levels of flow
resistance in the different heating or cooling circuits and, where
required, in the additional heating or cooling elements, are in
each case resulting in different compression ratios, which in the
end are leading to different flow ratios of the heating or cooling
medium. These complicate the pre-setting of the desired flow of the
heating and/or cooling medium as well as the control (which depends
on the room and/or return-flow temperature) of the heating or
cooling medium flow, to the point that it can result in
considerable and permanent differences in the room temperature.
[0005] It is known that in order to prevent these disadvantages a
flow control valve needs to be integrated into the flow line
between the pump and the distributor or into the return line
between the collector and the mixer. However, this one flow control
valve can only regulate the total flow of the heating or cooling
medium through the entire heating or cooling system. Thus, it is
not possible in this manner to control the flow of the heating or
cooling medium throughout the individual heating or cooling
circuits and, where required, throughout the additional heating or
cooling elements.
[0006] It is the objective of the invention to create a heating or
cooling system which makes it possible to control the flow in the
individual heating or cooling circuits and, where required, in the
additional heating or cooling elements, while keeping assembly and
installation of the said system cost-effective.
[0007] This objective is achieved with the heating or cooling
system according to the invention. Here a flow control valve is
integrated in each heating or cooling circuit, and this flow
control valve is located at the distributer or at the collector.
Whereby, according to claim 2, the flow control valves are
inventively located at the flow side heating or cooling circuit
connection of the distributor. According to claim 3, the flow
control valves are inventively located at the return side heating
or cooling circuit connection of the collector.
[0008] With these measures a heating or cooling system is created
which makes it possible to pre-set the flow of the heating or
cooling medium and to regulate this flow independent of the
pressure. With the integration of the flow control valves (which
ultimately react to the pressure of the heating or cooling medium)
at the distributer or collector the assembly and installation cost
will not increase. There will be no need to access the parts of the
heating or cooling circuits that will be inaccessible after the
installation of the said system.
[0009] According to the invention, the respective flow pressure
valve is integrated in the flow side heating or cooling circuit
connection of the distributor.
[0010] For the collector the valve is integrated into the return
side heating or cooling circuit connection. Thereby the appropriate
pre-assembled units, comprised of distributer and flow control
valve and/or collector and flow control valve, can be used for the
final installation on-site. Thus the assembly and installation will
remain cost-effective.
[0011] Additional advantageous embodiments and further developments
of the invention are the result of the characteristics of the
dependent patent claims 4 to 9.
[0012] For instance, it is advantageous to design the flow control
valves with an adjustment wheel for the simple adjustment of the
desired flow. This device permits the user to make easy and fast
adjustments, so that the needed flow speed can be achieved. A
further advantageous embodiment results from a blocking device
which is integrated into the flow control valve. This said blocking
device permits the user to block the heating or cooling circuits as
needed. Furthermore, it is advantageous to cover the adjustment
with a protective cover in order to prevent unwanted changes to the
pre-determined flow rate of the heating or cooling medium. On the
other hand, the distributor and/or the collector can feature an
additional manual blocking cap in order to disconnect the flow of
the heating or cooling medium. Another particularly advantageous
possibility is to furnish the distributor and/or collector with a
thermostat valve head by which it is possible to pre-set the
desired room temperature or return flow temperature. This even
further reduces the time and effort needed for assembly and
installation. Additionally, in place of the thermostat valve head,
an actuator can be used for the regulation of the desired room
temperature and/or return-flow temperature.
[0013] Embodiments of the heating or cooling system, the
distributors, and the collectors are illustrated in FIGS. 1 to 3.
They are closer explained in the following:
[0014] It is shown in:
[0015] FIG. 1 a schematic illustration of a heating or cooling
system with a distributor and a collector,
[0016] FIG. 2 a distributor of a heating or cooling system, and
in
[0017] FIG. 3 a collector of a heating or cooling system.
[0018] In FIG. 1 the heating or cooling system features a heat or
cold generator (10) which is connected to an agitator (12). The
heating or cooling medium if directed across a supply line (18)
from an agitator (12) via a pump (14) to a distributor (16).
Outgoing form this distributor (16) are two heating or cooling
circuit connectors (32) which are leading to the heating or cooling
surfaces (24, 26).
[0019] In FIG. 1 only the left heating or cooling circuit is
schematically shown in detail, so that the actual heating and/or
cooling surface (26), a room thermostat valve (28), and a return
flow temperature blocking valve (30) can be seen.
[0020] The heating and/or cooling medium of the heating or cooling
circuit (24) is directed back via return side heating or cooling
circuit connectors (34) to a collector (20). The collector (20) is
hydraulically connected to the agitator (12) via a return line
(22).
[0021] In addition to these standard components of a surface
heating or cooling system, the heating and cooling system that is
shown in FIG. 1 features for each of the heating or cooling
circuits (24) a flow control valve (36). Thereby the flow control
vale (36) for the heating or cooling circuit (24), which in FIG. 1
is shown on the right side, is located at distributor (16) of the
said heating or cooling system that is in the flow side heating or
cooling circuit connection (32) of the said distributor (16). For
the heating and cooling circuit, which in FIG. 1 is shown on the
left, this flow control valve (36) is located at collector (20)
that is at is at the flow side heating or cooling connection (32)
of the said collector (20). These are the two possible options
according to the invention, namely one on the flow side and the
other one on the return side.
[0022] These flow control valves make it possible to pre-set the
flow of the heating or cooling medium throughout the various
heating or cooling circuits (24). Thus the respective pre-set flow
rate of the heating or cooling medium in the individual heating or
cooling circuits (24) can be regulated unrelated to the pressure of
the heating or cooling medium in the distributor (16) and/or in the
collector (20).
[0023] Component parts in FIG. 2, which are identical or which
operate in the same manner, are identified by the same reference
numerals than in FIG. 1. In FIG. 2, next to the distributor (16),
which is shown as a tubular structure, the flow line (18) can be
seen, which is hydraulically connected with the distributor (16).
Visible are also the respective heating or cooling circuit
connectors (32) which are pictured schematically as well. Each of
these flow side heating or cooling circuit connectors (32) has a
flow control valve (36) assigned, which is screwed into the
distributor (16) and which, as it is shown in FIG. 2 on the top
side, makes the respective pre-setting of the desired flow rate
possible.
[0024] Component parts in FIG. 3, which are identical or which
operate in the same manner, are identified by the same reference
numerals than in FIGS. 1 and 2. In this FIG. 3 the collector (20)
is shown as a continuous line which is on the one side
schematically connected to the return line (22) and which is
connected hydraulically to the return side heating or cooling
circuit connectors (34). The flow control valves (36) are covered
on the left side of FIG. 3 by a protective cap (38), in the middle
of FIG. 3 by a manually adjustable cap (40), and on the right side
of FIG. 3 by a thermostat valve head (42); thus they cannot be
shown graphically.
[0025] Herby the protective cap (38) protects the flow valve (36)
from accidental alterations of the pre-set flow rate. In contrast,
with the manually adjustable cap (44) [Translator's note: In the
previous paragraph 40] the flow of the heating or cooling medium
can be manually shut off. Additionally, the thermostat valve head
is used to pre-set the desired room temperature or the desired
return flow temperature of the heating or cooling medium.
