Collector for heating: principle of operation, installation and connection rules. Floor collector module with decentralized hydraulic adjustment and individual accounting (according to consumers) How to set up a floor collector module sothis

One of the effective options for upgrading the heating system, which makes it more productive and reliable, is the installation of a collector unit. The device, which replaced the traditional linear structure designs, is designed to improve the ease of operation and maintainability of the system.

How the collector for heating functions and what installation features should be considered, we will consider in more detail.

Thanks to this distribution, each element is properly heated, supplied with a coolant of equal temperature.

The inner diameter of the collector is determined by calculation so that the speed of movement of the coolant inside it is not more than 0.7 m/s

Having reached the battery and given off the heat received during heating, the liquid is directed through another pipe in the opposite direction to the distribution block. There it enters the return comb, from where it is redirected to the heat generator.

Underfloor heating pipelines are assembled from copper pipes or their plastic counterparts, one-piece fittings are used for connections.

Valves are mounted in the heating rings, with the help of which they regulate the supply of coolant, and, if necessary, disconnect the "warm floors" from the common house heating network.

The collector for the "warm floor" is a structure that includes a number of pipe rings, which is laid under the floor covering

Such systems are always equipped. It is placed in an intermediate collector assembly at the inlet to the reverse direction pipe.

The number of nozzles on the distribution node depends on the number of rooms looped on one comb.

The number of collector groups is determined based on the length of the contours. The calculation is based on the ratio in which 120 meters of the pipeline are assigned to one collector group.

Type #2 - Hydraulic Arrow

When arranging powerful and branched heating systems that are designed in residential buildings with a large area, distribution manifolds equipped with thermohydraulic distributor or hydraulic arrow.

When installing the connecting link, on the one hand, the heating boiler circuit is connected to it, and on the other hand, radiator heating or “warm floors”.

Collector module MKT SOTIS-Unit is designed to connect consumers to the UUTEM-E metering unit on the floor, control the distribution of heat carrier between consumers and organize individual metering of heat energy consumption. Depending on the modification, the module can also perform the functions of conditional adjustment (limitation) of the coolant flow in apartment heating circuits or precise hydraulic balancing of apartment heating circuits.

The collector module is supplied assembled as part of the UUTEM-E metering unit, or as a kit for assembly directly at the facility. Assembly of the collector module and its installation on the pipeline must be carried out by specialists with the necessary qualifications, in accordance with the drawing given in the Technical Description.

The collector module can be installed on the pipeline in any of two mounting positions: horizontal or vertical.

With a horizontal installation of the collector module, which is used in most cases, heat meters (heat meters) are located vertically. If heat meters provide the required level of measurement accuracy only when they are operated in a horizontal position, the collector module must be installed vertically on the pipeline.

The collector module is installed on the pipeline by connecting it to the input module using connecting elements, such as nipples, fittings, connectors with an "American" union nut, etc. The connections of the collector module to the input module and pipelines of apartment heating circuits are threaded. As a seal of these connections, sanitary flax with sealing paste or a special plumbing thread should be used. Installation must be carried out using open-end wrenches or adjustable wrenches.

The connections of the individual elements of the collector module to each other are threaded detachable, their installation must be carried out using open-end or adjustable wrenches. Before hydraulic testing of the heating system, it is mandatory to pull all detachable connections!

(VT.GPM) Floor unit is used in water heating systems apartment buildings for the distribution of thermal energy to individual consumers and accounting for its consumption (when installing a heat meter). In addition, the module allows hydraulic balancing of consumers with each other.

Also, a storey unit for apartment-by-apartment metering of thermal energy allows for service operations: air release, coolant cleaning, drainage and system filling.

The module is connected to the distribution common pipeline of the heating system (riser), the input location is left (L) or right (R). Horizontal apartment one-pipe and two-pipe heating systems are connected to the outputs of the node. The diameter of the connection to the risers of heating systems is ¾ or 1”.

The maximum heat carrier temperature is 95 ˚С, working pressure is 10 bar.

The unit is supplied assembled, by separate order the unit can be delivered disassembled for subsequent assembly on site. It can also be equipped with heat meters, pressure gauges and automatic air vents. The assembled units are pressure tested with a test pressure of 15 bar.

As related products for the VT.GPM node are offered pressure gauge set VT.GP.31 , automatic air vents VT.GPM.41 , .

To fill out an application for the assembly and supply of a standard / non-standard storey manifold assembly, you must fill out order form.

The use of this module provides independent hydraulic adjustment of each apartment on the floor, and individual heat metering. To connect to central riser heating several apartments use a collector module with a decentralized (separated) system of hydraulic adjustment and accounting.

Each outlet of the collector is designed to distribute the coolant to a separate apartment. Each branch is equipped with shut-off valves, balancing valves and metering devices.

Module collectors for multi-apartment system have a large diameter (1"1/2 and 2" *) and an increased center distance of the outlets (100 mm). Ball valves and a strainer are provided for connecting, disconnecting the module and cleaning the coolant. A shut-off ball valve is installed on the manifold and, in addition, on the manifold supply there are manual balancing valves to control the flow of the coolant.

Automatic differential pressure regulators installed on the return manifold branches work in conjunction with manual balancing valves and serve to hydraulically stabilize the system. The module can be equipped with heat meters (heat meters), complete with ball valves, or places for subsequent installation of heat meters can be provided. On the outlets of the supply manifold, shut-off ball valves with a fitting for a temperature sensor are installed. End groups with automatic or manual (on request) air vents and drain ball valves are installed on the supply and return manifolds.

Threaded nipples and fittings (adapters) are used to connect all components to each other.

Pipes for connecting heating devices can be different - copper, polymer or multilayer (metal-polymer). Corresponding adapters and adapters are used for different pipes. By agreement with the customer, the modules can be equipped with adapters at the factory.

Installation of collector modules at the facility is carried out on brackets on the wall or on a special rail. It is necessary to place the modules in special niches or provide Technical buildings. An important condition is the possibility of access to the collector modules only for service personnel.
