Description

The invention relates to techniques for heating, ventilation, hot and cold water supply and heat supply.

A known system for supplying a building with heat and cold water, comprising heat and cold water supply pipelines brought to the building, shut-off valves, a heat meter, a water meter, distributing cold water supply pipelines and supply and return heat supply pipelines, corresponding risers with a heat exchanger connected to one cavity at the outlet to a pipeline with water supply mixers, and at the inlet to the riser of cold water, and the other cavity of the heat exchanger at the inlet to the supply, and at the outlet to the heating pipes, and circulation rings of consumer heating systems with supply and return branches (see Designer Handbook. Internal Sanitary Devices, Part 1, “Heating, Plumbing, Sewerage,” edited by I.G. Staroverov. M.: Stroyizdat, 1975, pp. 70-102).

These systems have the following disadvantages:

- require an increased number of heat meters and water meters (for hot water - a water meter and a heat meter; and a heating meter for a heating system, a heat meter for a ventilation system, etc.);

- they do not provide the consumer with a supply air heating during the organization of forced ventilation, which, when introducing sealed double-glazed windows, becomes an urgent need. And if there is a need for a ventilation device, it is additionally necessary to arrange additional laying from shut-off valves and a heat meter to the consumer of the heat supply pipes of the supply air air heaters with the installation of additional heat meters on the hoses;

- in addition, with modern construction practice, when the consumer cannot, at his discretion, decide on the temperature regime in the premises with the device of heated floors, without exerting a negative effect on other systems (hot water supply).

Known systems for supplying a building with heat and cold water, containing main pipelines for heat and cold water, shut-off valves, a heat meter, a water meter, distributing pipelines for cold water and supply and return pipelines for heat supply, corresponding risers, thermotransformer units with a heat exchanger connected to one cavity at the exit to the pipeline with water supply mixers, and at the entrance to the cold water riser, and the other cavity of the heat exchanger - at de to the feed, and the output - to the opposite heat risers and thermal consumer circulation ring systems with the supply and return branches (Anichhin AG "building heat supply system and with cold water (GP System)" Patent 2287743 C1 RU).

The disadvantage of these systems is the large load of thermal transformers with overall equipment, in particular, for each consumer thermal system, it is necessary to provide dimensional heat exchangers, expansion vessels, mixing devices.

The purpose of this proposal is to greatly simplify the implementation of systems, maximize the efficiency of the use of installed equipment, reduce the overall dimensions of thermal transformers.

This is achieved by the fact that the heat supply and water supply systems of the building or each consumer are open: all consumer heat systems are open. In other words, in all systems the same heat carrier circulates, which performs the function of a thermal temperature control system for the purposes of hot water supply. The coolant consumed for hot water supply is replenished in each consumer system with water from cold water pipelines. This is what allows us to reduce the number of heat exchangers needed, in some cases to abandon expansion tanks, to reduce the size of heat exchangers due to the mismatch between the heat consumption schedules of hot water supply systems and heating systems, floor heating, heat supply for air heaters of ventilation systems.

The invention is illustrated by drawings, presented in figures 1-7.

The system for supplying the building with heat and cold water contains heat pipelines connected to the building; 2 and cold 3 water supply, shut-off valves, heat meter, water meter, distributing pipelines of cold water supply (combined in the figure in the control and measuring unit) 4 and supplying 5 and return 6 heat supply pipelines, corresponding risers 7, 8, 9, thermotransformer units 10 with heat exchanger 11, connected by one cavity at the outlet to the pipeline 12 with mixers 13 of water supply, and at the entrance to the riser 9 of cold water, and the other cavity of the heat exchanger 11 at the entrance to the supply 7, and at the exit to the return 8 risers heat supply, and circulation rings 14, 15 of consumer heating systems with supply 16, 17 and return 18, 19 branches.

The system also contains auxiliary supply 20 and return 21 with the inducer 22 pipelines, the first of which 20 is connected to the heat exchanger 11, at the outlet of the pipe 12 with the mixer 13 supply, and the second to the heat exchanger 11, in the place of supply of the pipe from the riser 9 cold water supply, and each circulation ring 14, 15 of the consumer heating systems is connected by its branches 16, 17, 18, 19 to the corresponding auxiliary pipelines 20, 21.

The system can be equipped with an auxiliary mixing device 23 and a recirculation pipe 24, and the inducer 22 is placed on the return auxiliary pipe 21, between the connection to the latter 21 of the return branches 18, 19 and the heat exchanger 11, and the recirculation pipe 24 is mounted on the discharge side of the inducer 22 and connected through auxiliary mixing device 23 to the supply branch 16, 17 of at least one circulation ring 14, 15 of consumer heating systems.

Sometimes the system contains a hot water circulation pipe 25 and an additional mixing device 26, the latter 26 being installed on the pipe 12 with a water supply mixer 13, and a circulation pipe 25 connecting this device 26 to the return auxiliary pipe 21.

It is possible that at least one circulation ring 14 of the consumer heat system on the supply branch 16 or 17 is equipped with a circulation pump 27 with a mixing valve 28, the last of which is connected to the return branch 18 or 19 of the corresponding circulation ring 14. Systems are sometimes equipped with an expansion tank 29 and differential pressure regulators 30 (throttling devices).

To reduce the occupied building space, the system can be made so that the heat exchanger 11 and the inducer 22 are mounted outside the thermotransformer and at least two thermotransformers 10 are connected to them.

The system for supplying the building with heat and cold water works as follows: to the building through heat pipelines - 1; 2 and cold 3 water supply coolant and cold water. Having passed the gate valves, as well as the heat meter and water meter, depending on the requirements, they can be placed both at the entrance to the building, and for each consumer, and sometimes there, here, the distribution pipelines of cold water supply (in Fig. It is conventionally shown as a control measuring unit) 4 through the supply 5 and return 6 heat supply pipelines and the corresponding risers 7, 8, 9 with thermotransformer units 10 enter the heat exchanger 11. The heat exchanger 11 is connected by a single cavity at the outlet to the pipeline 12 with 13 v mixers supply, and at the entrance to the riser 9 cold water supply. In this cavity, water is heated for the purpose of hot water supply. The heating is carried out due to the heat supplied by the coolant passing through another cavity of the heat exchanger, which is connected at the inlet to the supply 7 and at the outlet to the return 8 heat supply risers. The circulation rings 14, 15 of the consumer heating systems with supply 16, 17 and return 18, 19 branches are connected by auxiliary supply 20 and return 21 to the inducer 22 by pipelines with heat exchanger 11. Moreover, the first of which 20 is connected to the heat exchanger 11, at the outlet of the pipeline 12 with mixer 13 water supply, and the second 21 to the heat exchanger 11, in the place of supply of the pipeline from the riser 9 cold water supply. Such a connection allows the use of hot water as a coolant in the circulation rings 14, 15 of the consumer heating systems, which are connected to the corresponding auxiliary pipelines 20, 21 by their branches 16, 17, 18, 19. Since in this embodiment of the systems, the coolant in the heat exchanger 11 must be heated to temperatures acceptable for heating and heat supply systems of ventilation, which exceeds the permissible temperatures in the hot water supply system, the system is equipped with an auxiliary mixing device 23 and a recirculation pipe 24, and the inducer 22 is located on the return auxiliary pipe 21, between the connection to the last 21 of the return branches 18, 19 and the heat exchanger 11. This allows recirculation return heat carrier of consumer systems and provide temperature control of the heat carrier in user systems according to an individual mode 16, 17 of at least one circulation ring 14, 15 of consumer heat systems

The system provides for the circulation pipeline of hot water 25 and an additional mixing device 26, the latter 26 being installed on the pipe 12 with a mixer 13 for water supply, and the circulation pipe 25 connects this device 26 to the return auxiliary pipe 21.

This connection allows you to adjust the temperature of hot water in the hot water system, regardless of the parameters of the coolant in the heat supply system.

To independently control the temperature of the coolant in consumer heating systems, it is possible at least one circulation ring 14 of the consumer heating system to equip the supply branches 16 or 17 with a circulation pump 27 with a mixing valve 28, the last of which is connected to the return branch 18 or 19 of the corresponding circulation ring 14 This constructive technique will allow you to adjust the temperature of the coolant in each supply branch of the consumer heating system. Sometimes systems are equipped with an expansion tank 29 and differential pressure regulators 30 (throttling devices).

To reduce the occupied building space, the system can be designed so that when the heat exchanger 11 and the inducer 22 are placed outside the thermotransformer with at least two thermotransformers 10 connected to it (group heat exchanger), the dimensions of the thermotransformers are reduced, the need for construction sites is reduced while all the above advantages are preserved the proposed system for supplying the building with heat and cold water.
