Heating system, circuits, and especially
I already showed you the options heating circuitsToday I want to elaborate on open one pipe heating system called in the vernacular "Leningradka". It enjoyed from Leningrad in Soviet times, unprecedented popularity, because such a system is easy to install. Basic elements of the heating system "Leningradka" - volatile gas boiler, batteries, tubing, and expansion tank. heating system type from Leningrad elementary, below is a detailed analysis, understandable even not really understanding on engineering communications devices.
Benefits "Leningradka"
- With this heating system supply pipe can be laid directly under the doorway;
- Low cost packaging system;
- Easy installation, with a small budget because of the low volume of work;
- Heating system aesthetic, minimum "protruding" pipes;
- Such a system can be connected in cascade, at the same time to the two heating boilers;
Leningradka lets go around the house with one ring on its outer wall. In this scenario, the conduit extends from the "heart" of the heating system as the feed, encircles the entire perimeter of the housing and returns to the return line. With Leningradka heating scheme allows to lay floor heating.
disadvantages of the system
- Loss of heat transfer, heat transfer will align only after adding additional sections followed radiators;
- Under the system of "horizontal Heating" with the use of metal pipes in the future is possible embarrassing dismantling radiators.
The operating principle of "Leningradka"
In the first series arrangement of the heating battery. The heating medium from the boiler (antifreeze, or water) is supplied to all radiators progressively giving heat to each battery. Here and opened disadvantage logical that if the first radiator with the coolant temperature dropped to 60C, in each subsequent battery cleared to 5C, for example in up to the fifth battery coolant comes with a temperature of 40 ° C already, in consequence of the back room, the site will be bad to warm up, so it should be put back and a radiator with a lot of sections.
Paying attention! Increasing the number of radiator sections according to their distance from the place of "feeding" heat retain heat balance among all rooms.
One-pipe heating system from Leningrad ideal for heating buildings with one or two floors. If the feed pipe is laid below the floor level, should promptly take care of its insulation using roll materials. Otherwise, it will be observed the loss of heat and there is a risk of overheating of the underground facilities.
The coolant is provided a continuous loop?
The heat medium heated to a desired temperature entering the battery according to the laws of physics, it is moved to the upper portion of the cavity radiator. The coolant with a lower temperature is lowered. The process of moving a heated heating medium upwardly and thereby pushing action more cold passes in the cycle. Colder coolant flows into the boiler heats up and it all starts again - cycles.
heating system installation features
Heating pipes laid along the entire perimeter of the apartment or house, and closed with the boiler. Near the boiler is Box and displays the vertical pipe on the expansion tank in the supply pipe. Expansion tank should be the highest point of the entire heating system and air vent, and serve as a fuse.
And! Just expansion tank creates in the pipework acceptable (optimal) coolant pressure.
In such a battery heating system connected to the main hole for the main pipe. It is used as a lower-through connection and bias-full bore connection.
To get acquainted with one pipe heating type "Leningradka" system and its functioning, you'll be able to video. Detail, and most importantly, available described the subtlety, nuances and ways of solving possible difficulties during installation of the system.
Modern one-pipe system, equipped with regulators, valves for balancing valves Thermostatic valves, ball valves - this makes it possible to balance the radiators, depending on your preferences. Simply put, if you have a radiator in the hallway, and in it you will spend less time than bedroom, the radiators at the site can be slightly muted, adjusting flow of coolant in battery. Also, if the heating system you are going to install on their own, should be taken into account when designing fact battery faults and in any case put the bypass and detachable coupling (American). This will allow you to shoot without turning off the radiator heating system, but only the overlap of only one radiator. It concerns only the first two circuits. The bottom diagram is not intended under the given conditions. cutting off the first battery you cover the entire heating system.
