CZ233891A3 - module air-conditioning unit with heat recuperation - Google Patents

Abstract

The unit consists of independent air-conditioning module parts (10), containing a chamber (6), located in which is a recuperative exchanger. Located on top of the chamber (6) is the first upper horizontal piping piece (1) and below the chamber (6) is the lower horizontal piping piece (3), whose inner space is connected with in the inner space of the chamber (6). The inner space of the second upper horizontal piping piece (2), located next to the first upper horizontal piping piece (1), is also connected to the inner space of the chamber (6), and by means of one wedge piping piece (5). With the purpose of creating a connected set of pipes from individual first (1) and second upper horizontal piping pieces (2) and lower horizontal piping pieces (3), there are independent air-conditioning module parts (10) arranged very close to one another in one row. By this arrangement it is possible to create a row system or paired system of independent module pieces (10). In the case of a paired arrangement of independent module pieces (10) in one alternative of their ordering, below the wedge piping pieces (5), a further piping space is created (4).<IMAGE>

Description

MODULE AIR TECHNICAL UNIT WITH HEAT PURCHASING

Technical field.

The tenla recuperation modular air handling unit relates to the creation of recuperation nodes in central air handling systems and substantially expands the possibilities of utilizing a recuperative heat exchanger according to the invention AO 219973/81. In particular, the improvement relates to the extension of the possibilities of constructing 'recuperation nodes in the form of a kit from a universal, serially' extensible component, which can be repeatedly used to create arbitrary assemblies of different air performance. and

The invention solves a whole complex of problems already arising from the design of recuperation centers in which it is necessary to achieve a state in which the waste air in a logical arrangement in the recuperation exchanger must be swelled with fresh air. In the presently used universal units, it is possible to create groups of various performances, while the mutual involvement of universal units has to be solved in a challenging manner in a non-tertiary way. This creates labyrinth-level assemblies whose utility value is low and the whole is violent. The pressure loss of such a whole is high and degrades its energy efficiency. Built-in filtration and air heating are almost impossible with these assemblies. The large enclosed astronomical space required to create such systems in many cases precludes the retrofitting of recuperation nodes in existing ventilation systems. The constructional, organizational and realization demands are considerable and inevitably entails shortcomings in the area of acquisition costs and thus the return on the whole investment.

SUMMARY OF THE INVENTION.

All these drawbacks are solved by the invention of a modular air handling unit with heat recovery. The essence of the modular component according to the invention, a module of a heat recovery air handling unit, is that by simply assembling several modules together - necessities. The module unit according to the invention further comprises built-in filtration and reheating of fresh air, making the unit non-usable even in the most expensive assemblies.

Description of the invention.

Claimed modular ventilation unit thus recovery / see figures / is composed of a pipe portion horizontally guided goal X, _r 2 J, but two key vitých connector parts ^{and a} chamber 6. The chamber 6 includes a built-in filter 7, its own recuperative heat exchanger 8 and an air heater 9. The unit can be repeatedly assembled into row assemblies or pair assemblies. In-line assemblies can be advantageously used in enclosed spaces. By landing? to the wall, the fourth piping / pressure / space · £ is created in a logical form by the wall and the floor, which also serves as a revision corridor. When creating a paired assembly, the function of the created space is similar. Since the assembled piping spaces are in all cases accessible from the outer space of the whole, the connection of the entire assembly to the external piping system can be solved very easily and according to the specific needs of individual assemblies. Particularly preferred is a row assembly attached to the peripheral wall of the object. While the recuperation node assembly is located in the enclosed space, the ventilation system drive can easily be placed outside the building. This creates the basic conditions for perfect sound insulation of the whole system. Low weight of one module / max. 400 kg / allows you to build in-line assemblies even in hanging galleries without taking over the floor's floor. One of the main advantages of the modular air handling unit with heat recovery is the fact that by repeatedly using the same part, it is possible to design, design and build recuperation nodes with the olynulous removal of the required air output from about 5,000 m / / h. up to 100 000 mVfeod. Modular air handling units with heat recovery can be produced on an almost large-scale level, which inevitably brings the investment unit into significantly more favorable prices. _E From the design point of view, each assembly will form a compact logical unit - without visual or functional violence.

Description of illustrations.

In the upper left part, the array of modular units is spatially depicted with weak lines. In the lower part of the same figure, a modular unit is shown in thick lines as the beginning of the paired assembly.

In the lower part, the actual function of the heat recovery node is shown in two sections of the modular unit row assembly.

In section A-A, one of the possible situations is shown in which the exhaust air is led through the duct 3 to the recuperation exchanger 8 from which it passes through the wedge duct 5.

and the horizontal duct 1 is discharged. In section B-B, fresh air is supplied to the duct space 4, from where it passes through the filter 7 of the recuperation exchanger 8, the heater 9, to the horizontal duct 2. from where it is further led to the distribution piping. In both sections, the function of the wall and the floor, to which the row assembly is added during the formation of the duct 4, is well visible.

Application example. The patent solution is implemented for the first time in the Ceramics factory in Pščín, plant Varnsdorf. The investment plan of Ceramic Plants for the Ventilation of Technological Styrenes resulted in a demand for the inventor to create a reconditioning air-conditioning node with an air output of 40,000 m ^ / h. The whole node had to be built into a space of 2 m X 6 m height 2.5 m. This object has been achieved by the invention. The recuperation node in a row set of four modular units will be put into trial operation in April 1991. (1) A modular air-conditioning unit with a recuperation of the theorem characterized in that a three-point oro-connecting notrubbing system (1 / _r / 2 /, / 3) is formed by the multiple multiple alignment of the same component, the fourth notrubbing nrostor (4) being a wall and a floor. to which the unit is cleaned or the wall and oodlaft with which the unit is equipped. 2) A modular air handling unit according to claim 1, characterized in that the fourth duct space (4) is formed by the rear side of the steam of the unassembled row of modular units and the tension on which the coating assembly is set.
