EA041609B1 - 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 СР 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 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, a central high-pressure pump, a central system control unit, a hydraulic accumulator block, from which a central high-pressure water line and a drainage water line for flushing depart, from the central high-pressure water supply line, floor-by-floor high-pressure water lines looped for the possibility of flushing, to which consumers are connected, each of which has its own hydraulic system, including adiabatic humidification spray nozzles, hydraulic fittings, distribution valves, hygrostats, room humidity control panel, maintaining air humidity at the set level, the control and management of which is carried out through the consumer control unit, while the central control unit of the system The sensor is configured to receive data from consumer control units. The hydraulic accumulator unit is one or more interconnected membrane storage tanks.

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.

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, floor (PVD) 2 and central (CVD) 3 high pressure water lines (pressure is maintained within 55-70 bar), drainage water line 4 for flushing, station water treatment (osmosis for water treatment) 5, central high pressure pump 6 and hydraulic accumulator unit 7, N-oe number of consumers 8, consumer control unit 9, central system control unit 10.

The principle of operation of the system is as follows.

Unprepared water from the centralized water supply of the house enters the water treatment station 5. Having undergone complete purification, the already prepared water enters the high-pressure pump or group of pumps 6, from where it already enters the storage accumulators 7 under high pressure, which are necessary to maintain constant pressure in the central high-pressure water supply line. pressure 3. The central high pressure water line 3 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, floor-by-floor, looped for flushing, high-pressure water lines 2 depart from the central high-pressure water line, a specific consumer 8 is connected directly to them. The number of possible consumers, as well as floors, is determined by the performance of water treatment equipment 5, the parameters of the pump or group high-pressure pumps 6 and a hydraulic accumulator block 7. Consumer 8 is a separate apartment / office in the building, inside the premises of 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 control of the operation of the nozzles is carried out

through 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 room system 1. Data from the control unit 9 is sent to the central control unit (CBU) 10 of the entire building, which is also a microcircuit with a processor operating according to a program that provides the necessary logic for the operation of the entire system. The central control unit 10 is also responsible for controlling the water treatment station 5, the pump or a group of high-pressure pumps 6, as well as all hydraulic equipment and fittings that ensure the organization of certain system operation scenarios, in particular, the opening of the consumer's valves at the right time to feed into the hydraulic system of his apartment /office/premises with high-pressure water for the correct operation of humidifying nozzles, as well as the organization of such service operations as flushing, by discharging water from the floor high-pressure water lines (HHP) and the central high-pressure water line (HPC) into the drainage line (D ), 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. Consumer 8 is connected by cutting into the floor-by-floor pressure water line of two supply pipes, in turn, the floor-by-floor pressure water line is also connected by two pipes to the central pressure water line. The central pressure water line connects all floors of a building or a group of floors into a single line, powered by a pressure station, including a water treatment station, a central high-pressure pump and a hydraulic accumulator unit. Water treatment station 5 consists of a block of filters of various degrees of purification, as well as a reverse osmosis system. The central high pressure pump or a group of high pressure pumps is a single pump or several pumps combined into one circuit that pump high pressure into the high pressure water line. The hydraulic accumulator unit is one or more interconnected membrane storage tanks. The control unit of the consumer controls the operation of the distribution valves responsible for the opening and start of liquid distribution based on the data received from the hygrostat, and also allows the consumer to set the boundaries for the start and end of humidification. The central control unit includes a microcircuit with a processor and controls all consumer units, and also, based on their data, turns on or off the central high-pressure pump (or group of pumps). The flushing drain line is a pipe through which, when the system is discharged or flushed, water from the high pressure water line enters the central sewer. The advantages of the claimed air humidification system are 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.
