Comparison of the claimed technical solution with the prior art known from the scientific, technical and patent documentation on the priority date in the main and related sections did not reveal a tool that has features that are identical to all the features contained in. The utility model proposed by the applicant, including the purpose of the assignment. That is, the set of essential features of the claimed solution was not previously known and is not identical to any known technical solutions, therefore, it is in compliance with the patentability condition of “novelty”.

This technical solution is industrially applicable, since its purpose is indicated in the description of the application and the name of the utility model, it can be manufactured industrially and used to create comfortable temperature conditions in human habitats.

The technical solution is workable, feasible and reproducible, and the distinguishing features of the device allow to obtain the desired technical result, i.e. are significant.

The utility model in the form as described in each of the claims can be implemented using the tools and methods described in the prototype, which became public until the priority date of the utility model. Therefore, the claimed technical solution meets the condition of patentability "industrial applicability".

The device operates as follows.

When air is supplied to the device (Fig. 16) by the fan 12 into the “hot” zone 5 and the “cold zone” 6, hot or cold air is selectively supplied to the consumer 13, and the air of an unused temperature state is thrown out of the inhabited object or disposed of.

The operation of the device according to the embodiment of FIG. 1 for the fuser unit 1 with six batteries 2 is carried out by supplying external or internal air to the fan 12 with preliminary cleaning by the filter 11. Then, the air passes through the intake manifold 7 through all channels 5 and 6 of the fuser 1. It is heated in the channels 5, and in channels 6 it is cooled. Depending on the required temperature, air is either supplied to the consumer 13 either manually or using a processor 33 from the exhaust manifolds 14 or 15. In this case, the supply of hot or cold air is regulated by a lever 26 connected to the blocked thrust 25 by the shutters 27 and 28.

In the embodiment of FIG. 3, the polarity at the terminals 30 of the Peltier modules 3 is changed manually or by means of a processor 33, due to which the temperature in the exhaust manifolds changes from hot to cold, therefore, separate collectors for hot and cold air are not needed here, and the air of the required temperature enters into the same duct.

The practical implementation of the device, for example, on the tram 34, is as follows. Above the doors in the passenger compartment and in the driver's cab, shrouds 4 of a thermal or cooling curtain are installed. These elements of the device can be made according to the design of figure 1 - figure 20 with independent thermal units. To control the temperature of the internal air, heating and cooling devices 35 are installed. A direct current of 600 V DC is supplied to the device according to the circuit shown in Fig. 8. The operation of the devices is controlled by the driver or using the processor 33.

For vehicles with DC batteries, the connection schemes of the device of FIG. 5, FIG. 6, FIG. 7 are used.

When using the device in rooms with AC power 220 / 380AC, the circuit of Fig. 14 is used, where the alternating current in the converter 31 is converted to direct current and supplied to the heating-cooling device. The range of alternating current can be from 110V AC to 660V AC.

Using the device allows you to provide a comfortable environment in a person’s living environment by increasing the radiated power of thermal units and device performance, improving performance by expanding the used DC range.

The heating and cooling device can be used on vehicles in the door zone to protect against penetration of outside air into the cabin, i.e. for the formation of the so-called "thermal curtain".
