Description

The invention relates to the heating of swimming pools, baths, dry cleaners, saunas, dryers in the inter-heating period, when the boiler room or central heating station (central heating point) operates in hot water mode, i.e. central heating is off.

This result is achieved by transferring the connection point of the direct and return heating water pipes with the addition of several shut-off elements (valves, ball valves, valves).

In normal practice, the construction of public baths, dryers and dry cleaners begins with the construction and commissioning of a boiler room, providing them with heating, hot water and steam.

In the future, if the capacity of the boiler room allows, residential houses, child care facilities, schools, etc. are connected to it. And only in recent years the construction of saunas, swimming pools, dryers has begun intensively. A characteristic feature of these objects is high humidity, the need to maintain a sufficiently high temperature of both air and water. During the heating season, this problem is removed by itself. During the inter-heating season, it becomes relevant and quite acute.

1. The technical field to which the invention relates: power engineering.

2. The level of technology: no analogues are installed.

3. The objective of the invention is to reduce the consumption of gaseous fuel, fuel oil, solid fuel and electric energy.

During the heating season, the operation of the boiler room (CHP) consists in providing the heating medium (water) with three heating circuits (see drawing).

The operation of circuit "A" is carried out according to the following chain: coolant (water) from the return line through point 3 (connection), open ZOM valve (return valve), when the DZOM valve is closed (additional valve of the return line), and the pump enters the boiler, where heats up to the required temperature and enters the direct (supply) line, bypassing points 1, 5, the open ZPM valve (direct line valve), enters the main heating facilities of the public district (residential buildings, child care facilities, schools, hospitals) and then return th line, giving the heat returns to point 3.

The operation of circuit "B" - the hot water supply system - takes place along the chain, as in circuit A, to the point of connecting the direct line 1. Then, from point 1, through the open shutter of the VIZ (shutter of the water heater), water enters the water heater, in which it heats cold water and hot water of the loopback of the hot water supply system and, having given heat, through the open gate valve ZOMVP (gate valve of the return line of the water heater), the connection point 6 returns to point 3.

The circuit "B" operates to point 2, as during circuit A to point 2, then through PMSO (direct line of specialized facilities), through the open gate valve ZPMSO (valve of the direct line of specialized facilities) through the CO return line, through point 6 water enters to point 3 and further to pump N.

In the inter-heating period, the boiler room operates in the hot water supply mode described above as circuit "B" operation, with the difference that the ZPM valve (direct line valve) is completely closed.

The technical solution for heating specialized facilities in the inter-heating period, which is the objective of this invention, is as follows:

1) make an additional line from point 5, valve ДЗПМОСО (additional valve of a direct heating line for specialized facilities), point 4;

2) make an additional line from point 7 through DZOMOSO (additional gate valve for the return heating line of specialized facilities), point 8;

3) stop the operation of the boiler K;

4) stop the pump N;

5) drain water from sections from point 1 - point 2 - PMSO valve (ZPMSO valve);

6) close the gate valves on the direct highways in the pits of the specialized facilities and the ZOMSO valve (the gate valve of the return line of the specialized facilities;

Note: water is drained in order to improve metal heating during electric and gas welding works.

7) weld an additional line made according to claim 1 to point 5 and point 4. Point 5 must be located in front of the gate valve of the straight pipe;

8) they weld an additional line made according to claim 2 to point 7 and point 8. Point 8 must be located after the gate of the reverse manifold ZOM;

9) bring the circuit into working condition corresponding to the mode of operation of the boiler in hot water mode.

After completing the work of claims 1 to 9, specialized facilities are heated along the chain (with closed valves ZPM (direct-gate valve) and ZOM (gate-return valve), point 5, DZPMSO, point 4 (with the closed valve ЗПМСО), СО - specialized objects, ZOMSO, point 7, open gate valve DZOMSO, point 8, pump N, boiler K, point 5.

The work according to this invention is carried out by regular maintenance personnel and require low material costs.

Practical use.

Work on the manufacture of the invention is carried out by regular maintenance staff and, as a rule, at night, so as not to create inconvenience to the public.

Connecting and disconnecting this heating system is also carried out by regular staff and almost always at night, when the consumption of hot water is minimal.

The practical result: when using this invention for 7 hours - from 23.00 to 06.00 - the air temperature in the swimming pool reaches 26 ° C, the water temperature in the 25-meter pool with 4 paths reaches a comfortable 24-25 ° C. By the way, if necessary, this invention can be used in the daytime for heating saunas, dryers, dry cleaners. The additional consumption of gaseous fuel, fuel oil is not required.

When using this device, the need to use gas and electric heaters disappears, in which the air temperature in the premises of the swimming pool, saunas cannot be raised above 18-20 ° C, and the water temperature in the pool cannot be raised above 18 ° C, and the costs are about 300,000 rubles per month, which makes subscription prices prohibitive.

The operation of the device for heating swimming pools, baths, saunas, dry cleaners, dryers is illustrated by the scheme, see the drawing, where:

- 1, 2, 3, 4, 5, 6, 7, 8 - connection points of the direct and return heating water lines;

- ZPM - gate valve of the main main line;

- ZOM - gate valve of the main return line;

- ZPMSO - gate valve of the direct line of specialized facilities;

- DZPMSO - additional gate valve of the direct CO line;

- ZOMSO - gate valve of the return line WITH;

- PB - swimming pool;

- C1 - sauna;

- C2 - dryer;

- X - dry cleaning;

- B - bath;

- VIZ - valve of the direct line of the water heater;

- VP - tubular or plate water heater;

- ZOMVP - valve of the return line of the water heater;

- K - boiler;

- N - circulation pump;

- DZOMSO - additional gate valve return line of specialized facilities;

- OO - heated objects (residential buildings, child care facilities, schools, medical facilities);

- ХВ and ГВ - cold and hot water.

In the inter-heating period, only circuit “B” operates continuously - a hot water supply system, the operation of which is described in detail above.

If it is necessary to turn on the heating of specialized facilities, DZPMSO is opened and heating water through point 4 is fed to the heating of PB, C1, C2, X, B. Having given heat, through the return line of the OMSO, the ZOMSO valve, point 6, point 7, the DZOMSO valve goes through point 8 to the circulation pump H and to the boiler K.

Note:

1. Before heating of specialized facilities begins, the DZOMSO valve must first be opened first and only then the DZPMSO valve to prevent water hammer.

2. Be sure to check the closing of the valves ZPM, ZOM, ZPMSO.
