EA041612B1 - AIR HUMIDIFICATION SYSTEM OF A MULTI-STOREY BUILDING - Google Patents

Description

The invention relates to air conditioning technology and is used to create comfortable microclimate conditions in multi-storey buildings, in particular, to maintain a sufficient level of air humidity in an apartment building, offices and other similar buildings.

There are solutions to maintain air humidity at a certain level in multi-storey buildings by installing a humidifier / evaporator centrally in the supply and exhaust system of the building. The Hygromatik HL90 SR heating steam humidifier of the HeaterLine series with the Comfort Plus control system can serve as an analogue /). The first disadvantage of such a solution is the need for the mandatory presence of a supply ventilation system, the second disadvantage is the impossibility of local humidity control in a separate section / room of the structure, the third disadvantage is the high cost of installation due to the need to design a supply hood, as well as the limited possibility of its installation, the fourth the disadvantage is the high cost of maintenance, since the formation of steam is carried out by electric heaters that consume a large amount of electricity, and also during evaporation, scale remains on the heaters due to which the heater's life is limited to 2-3 flushing of the heaters from scale, after which the heater needs to be replaced.

The task to be solved by the claimed technical solution is to provide great flexibility of system variations, since it has no restrictions on the number of consumers per floor and restrictions on the maximum number of floors.

This problem is solved by the fact that the air humidification system of a multi-storey building includes a water supply pipeline from a centralized water supply system, a water treatment station, from which a central water line and a drainage water line for flushing depart, a central control unit for the system, floor loops depart from the central water line for flushing high-pressure water lines, which are powered by floor high-pressure pumps, each of which is equipped with an individual control unit, consumers are connected to the floor water lines, each of which has its own hydraulic system, including adiabatic humidification spray nozzles, hydraulic fittings, distribution valves, hygrostats , panel for adjusting the humidity of the room, maintaining the humidity at the set level, the control and management of which is carried out through the control unit of the consumer in this case, the central control unit of the system is configured to receive data from the consumer control units and pump control units.

The proposed technical solution makes it possible to systematize and centralize the air humidification system of a multi-storey building using adiabatic nozzle spraying of water under high division, in which the high pressure source is centralized by combining the pressure water lines of the floor into a single pressure water line with the possibility of further combining it into a common pressure water line of the entire buildings or individual floor groups.

The general layout of the adiabatic humidification system of a multi-storey building is shown in the drawing.

The diagram defines the main layout elements such as apartment / office / room 1, high pressure floor water line (HHP) 2 (pressure is maintained within 55-70 bar), treated water central line (CPV) 3, drainage line (D) for flushing 4, water treatment station (osmosis for water treatment) 5, high pressure floor pumps 6, each of which is equipped with an individual control unit (BUN) 7, N-oe number of consumers 8, consumer control unit (CCU) 9, central system control unit 10, which receives data from all pump control units (BUN) 7 and consumer control units (BUP) 9.

The principle of operation is as follows: untreated water from the centralized water supply of the house enters the water treatment station - osmosis 5. After being completely cleaned, the already prepared water enters the central line of prepared water 3, which passes through all floors of the building, while the maximum number of floors is determined by the performance of the equipment . On the necessary spans of the building, high-pressure floor pumps 6 are installed, from which floor high-pressure water lines 2 looped for flushing are powered, directly to which a specific consumer 1 is connected. The number of possible consumers, as well as floors, is determined by the performance of water treatment equipment 5 and pump parameters high pressure 6. Consumer 8 is a single apartment/office in the building. Inside the premises of the consumer 8, its own hydraulic circuit is organized from hydraulic fittings and structural elements necessary for organizing the operation of the system. Adiabatic high-pressure atomizing nozzles are installed in customer-specified rooms to maintain the humidity at a set level. Control over the degree of humidity, as well as the operation of the nozzles, is carried out by the consumer control unit (CCU) 9, the data from which is sent to the central control unit 10 of the entire building.

the control unit, among other things, is responsible for controlling the water treatment station 5, floor control units for high-pressure pumps 6, all hydraulic equipment and fittings that ensure the organization of certain scenarios for the operation of the system, in particular, opening the consumer’s valves at the right time to supply the hydraulic system of his apartment / high-pressure water office for the correct operation of humidifying nozzles, and the organization of such service operations as flushing by discharging water from the high-pressure floor water lines 2 and the central treated water supply line 3 into the drainage line 4, which is connected to the central sewerage of the building. Consumer 8 (apartment / office / room 1) means a room or a group of rooms with adiabatic humidification spray nozzles installed inside them, hydraulic fittings (for example, high pressure hoses (HPH), fittings, valve blocks for distribution valves), distribution valves, hygrostats and room humidity control panel. The logic of operation consists in monitoring the level of humidity in the room by means of hygrostats, when it decreases below the set level, the control unit 9 sends a signal to open the humidifying nozzles, after reaching the set maximum humidification, the control unit 9 sends a signal to close the nozzles. The connection of the consumer 8 is carried out by cutting two supply pipes into the floor-by-floor pressure water line. In turn, the floor pressure water line is connected by two pipes to the high pressure pump 6 and through it to the central low pressure water line 3. The central low-pressure water line connects all floors of a building or a group of floors into a single water line, from which a high-pressure pump is powered on each floor. Water treatment station 5 consists of a block of filters of various degrees of purification, as well as a reverse osmosis system. The high pressure pump 6 is a pump fed from a central low pressure water line. The pump delivers high pressure to the high pressure water line. This pump is installed on each floor and its power is calculated based on the number of consumers on this floor. Each pump has its own control unit 7, which regulates the speed of the pump motor in order to maintain a constant pressure in the system. The consumer control unit 9, which is a microcircuit with a processor operating according to a program that provides the necessary logic for the operation of the system, controls the operation of the distribution valves responsible for opening and starting the distribution of liquid based on data received from the hygrostat, and also allows the consumer to set the start and end boundaries moisture. The central control unit 10 includes a chip with a processor and monitors all consumer control units and pump control units, and, based on their data, turns the high pressure pump on or off. The drainage line 4 for flushing is a pipe through which, when the system is discharged or flushed, water from the central water supply line of treated water enters the central sewer. The advantages of the claimed air humidification system is that there is no need for a centralized supply ventilation system; the possibility of point installation in separately localized rooms with the possibility of adjusting the humidity of each room separately; lower cost due to the centralization of the high pressure source and the absence of additional equipment; low maintenance cost.
