Node storey for apartment-by-apartment metering of thermal energy. Collector for heating: principle of operation, installation and connection rules Why do we need a floor collector module

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”.

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

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 systems have a large diameter (1"1/2 and 2" *) and increased center distance of taps (100 mm). To connect, disconnect the module and clean the coolant, Ball Valves and strainer. A shut-off ball valve is installed on the manifold and, in addition, there are manual balancing valves on the supply manifold 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 temperature sensor. 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). For various pipes appropriate adapters and adapters are used. 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 rooms. An important condition is the possibility of access to the collector modules only for service personnel.

* Diameter 2″ on request (optional)

(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 unit, a set of pressure gauges VT.GP.31, automatic air vents VT.GPM.41, are offered.

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