Description

The utility model relates to the field of ventilation and air conditioning and can be used to create a microclimate in residential, public, administrative and industrial premises.

The inventive utility model relates to priority areas for the development of science and technology "Technologies for creating energy-saving systems for transporting, distributing and consuming heat and electricity" [Alphabetical and subject index to the International Patent Classification in Priority Areas for the Development of Science and Technology / Yu.G. Smirnov, E. V. Skidanova, S. A. Krasnov. - M .: PATENT, 2008. - p. 58 and p. 97].

At negative outside temperatures, as well as with certain combinations of temperature and relative humidity of the air removed from the room, it is possible to freeze the heat energy recuperator included in the ventilation or air conditioning units. To combat freezing, various methods are currently used:

1. For plate cross-flow heat exchangers:

- installation of a pre-heater of the supply air for its heating to temperatures excluding freezing;

- stop the supply fan to defrost the heat exchanger;

- a device for bypassing part of the outside air bypassing the recuperator;

- bypass device with sectional defrosting of the recuperator;

- the use of the mixing section for air recirculation to increase its temperature;

2. For rotary recuperators:

- reducing the rotational speed of the rotor motor;

- stop the supply fan to defrost the heat exchanger.

Thus, solving the problem of uninterrupted functioning of installations for ventilation and air conditioning systems in the winter period of time seems to be an urgent task.

A device for an air conditioning system is known, comprising means for transferring exhaust air and incoming air through an air conditioning system, a heat recovery device having two stages and means for introducing additional heat or cooling energy into the incoming air (SU 1474339 A1, F24F 5/00, published on April 23, 89).

Signs of an analogue that coincide with the essential features of the inventive installation are the availability of means for transmitting and processing incoming and exhaust air through an air conditioning system.

Signs of an analogue that coincide with the essential features of the claimed installation are: means for transmitting and treating the outgoing and external air and a device for the regeneration of thermal energy.

The disadvantage of the prototype is also the insufficient range of its operating temperatures, since the possibility of device stops in the winter period of time due to freezing of individual components of the device is not ruled out.

A device for an air conditioning system comprises heat recovery means and means for supplying additional heating and cooling, in which at least one heating or cooling device is installed in the incoming air stream, the liquid side of which is connected to the heating or cooling device.

A disadvantage of the known device is the high energy consumption for heating and cooling the air, as well as the inability to utilize excess heat.

The problem to which the claimed utility model is directed is to create a device that allows you to work both in summer and in winter.
