Description

The invention relates to pharmaceutical medical and microbiological technology.

A known construction of a box for working with highly pure substances, containing a horizontal rectangular housing of the working chamber, additional chambers with perforated side walls located on the front wall of the housing, to which exhaust ducts SU 867411 A are connected (Malyutenkov P.S., etc.), 09/30/1981.

The disadvantage of this design is that it does not completely solve the complex problem of the reliability of environmental protection from technological emissions and the cleanliness of the working area.

Another well-known technical solution is an isolated cleanroom containing the enclosing structures of the existing building, a supply and exhaust ventilation system with fine filters, a gray (transitional) zone, a perforated raised floor, collapsible building structures, a transitional vestibule, a clean zone, a perforated suspended ceiling and a ceiling chamber RU 2017525 C1 (Grigoryev V.V.), 08/15/1994.

This design of an isolated cleanroom has several disadvantages:

- the complexity of the design of cleanrooms (perforated raised floor, perforated suspended ceiling, ventilation duct system);

- the remoteness of the supply ventilation filter of fine cleaning from the clean zone;

- lack of exhaust ventilation system serving the transitional vestibule;

- high energy costs for the operation of supply and exhaust ventilation systems;

- lack of reuse of cleanroom air;

- The high cost of air conditioning serving clean rooms.

The closest in essence to the invention is an experimental-technological box containing a room for a working area of a box, a room for a transition zone, a common supply ventilation system equipped with control valves with an air supply duct for supplying ventilation air directly to the upper part of the room of the transition zone, adjustable supply and exhaust devices, corner ducts , sealed enclosing building structures of the premises of the working area and transition zone with suspended ceilings, insulated ovannye ceiling chambers of the premises of the working zone and transition zone, communicated with the corresponding room through their corner ducts and adjustable air intake devices installed in their lower part, ceiling filter chambers installed in the suspended ceiling, fine filters, self-contained supply fan with pressure air duct, self-contained exhaust fan, the intake pipe of which is connected to the insulated ceiling chamber of the premises of the working area RU 2303200 C2 (Grigoryev V.V.), 07.20.2007.

This design has several disadvantages and does not provide comfortable conditions due to:

- the lack of autonomous air coolers in the transitional area and its ceiling chamber;

- the lack of the ability to supply fresh air for ventilation in the isolated supply chamber of the transition zone premises, and in the transition zone;

- the lack of the possibility of intake of the transitional zone of the supply air received into the ceiling chamber and its supply in transit through the duct into the working zone through the ceiling filter chamber.

An object of the invention is to eliminate these disadvantages and improve comfort conditions while reducing energy consumption.

The problem is solved and the technical result is achieved due to the fact that the experimental-technological box contains a working area of the box, a transition zone, a general ventilation system equipped with control valves, an air supply duct for supplying ventilation air directly to the upper part of the transition zone, adjustable supply and exhaust devices, corner ducts, sealed enclosing building structures of the premises of the working area and transitional ones with suspended ceilings, insulated ceiling chambers of the working area and transition zone, communicated with the corresponding room through their corner ducts and adjustable air intake devices installed in their lower part, ceiling filter chambers installed in the suspended ceiling, fine filters, self-contained supply a fan with a pressure duct, an autonomous exhaust fan, the air intake of which is connected to the insulated ceiling chamber of the working area, while new m is that the supply air duct is made in the form of a tee, with the possibility of supplying ventilation air both to the insulated supply chamber of the transition zone room and to the transition zone room, the intake pipe of an autonomous supply air fan is connected to the insulated ceiling chamber of the transition zone room and made with the possibility of sampling received in the ceiling chamber of the transition zone of the supply air zone and its supply in transit through the duct into the working area is placed through the ceiling filter chamber, a branch pipe is made on the pressure duct of the autonomous exhaust fan, with a control valve and communicating with the isolated ceiling chamber of the transition zone room.

The best technical result is achieved due to the fact that air coolers are installed in the transition zone room and its ceiling chamber to cool the incoming air.

An experimental-technological box containing a room 1 of the working area of the box, an isolated ceiling chamber 2 of the room 1 of the working zone, a room of 3 transition zones, an isolated ceiling chamber 4 of the room 3 of the transition zone, an autonomous supply fan 5, its pressure duct 6, and a ceiling filter chamber 7 , autonomous exhaust fan 8, fine filters 9, pressure duct 10 of the autonomous exhaust fan 8, branch pipe 11, tee of the duct 12 for supplying fresh air from a common supply ventilation system 20, control valves 13, air cooler 14 of the transition zone room, air cooler 15 of the ceiling chamber 4 rooms 3 of the transition zone, corner ducts 16, adjustable exhaust devices 17, adjustable air intake device 18, air intake pipe 19, common air supply system 20, air duct 21 general supply ventilation system 20, suspended ceiling 22 of the room 1 of the working area, suspended ceiling 23 of the room 3 of the transition zone.

The principle of operation of experimental technological boxing is as follows. The external supply air from the general supply ventilation system 20 from the duct 21 is separately supplied to the transition zone, part of it is supplied directly to the upper part of the transition zone room 3, and the other part is supplied to its insulated ceiling chamber 4 of the said room 3, from which the incoming air taken by an autonomous supply fan 5 and fed in transit through the duct 6 into the cavity of the room 1 of the working area of the box, through the ceiling filter chamber 7 installed in its suspended ceiling 22.

The supply ventilation air entering the transition zone 3 from the general supply ventilation system 20 is removed from its lower part through adjustable air intake devices 17 and corner ducts 16 connected to its insulated ceiling chamber 4, an autonomous supply fan 5.

Removal of the supply ventilation air from the lower cavity of the room 1 of the working area of the box is carried out by an autonomous exhaust fan 8, the intake pipe 19 of which is connected to an insulated ceiling chamber 2, which communicates with the cavity of the room 1 of the working area through its angular air ducts 16 and through adjustable air intake devices 17 installed at their bottom.

Remote supply ventilation air from the room 1 of the working area, having been cleaned in the fine filter 9, in order to save energy and increase the frequency of air exchange in the cavity of the room 1 of the working area through the branch pipe 11, most of this air is sent to the insulated ceiling chamber 4 of the transition zone 4, and a smaller part is sent to the atmosphere through the pressure duct 10. The quantitative volume of the box directed to the atmosphere removed from the room 1 of the working zone depends on the technological requirements and comfortable working conditions in the working area of the box.

In the warm season, the normative cooling of the supply ventilation air coming from the general supply ventilation system 20 to the transition zone room 3 is carried out in air coolers 14 and 15 installed in the transition zone 3 room 3 and its ceiling chamber 4.

In the device of the experimental-technological box, the energy resource of the supply ventilation air supplied to the room 1 of the box’s working zone is maximally used while ensuring a high air exchange rate in it of clean air. Energy costs for regulatory comfort conditions in the premises of the working area of the experimental-technological box are minimal.
