FIELD OF THE INVENTION The invention relates to a transport engineering, in particular to air conditioning installations.

The purpose of the invention is to increase efficiency and thermal maneuver.

Pa figs. 1 shows the proposed arrangement for vehicle air conditioning, a general view; in fig. 2 - radiation-convective panel, longitudinal section; in fig. 3 - the same, top view.

The vehicle air conditioning device contains a radiation-convection panel 1, the air channels 2 of which are connected by means of an air duct 3 to a thermoelectric cooling unit 4. The thermoelectric batteries 5 of the panel have thermal contact through the ten-junction layer 6 with separate radiation surfaces plates 8. Air ducts 2 panels have air distribution nozzles 9, which regulate and distribute the air flow, but at the same time filter 11. The heat removal system from the hot junctions of a thermopile consists of an air-liquid radiator 12, a water pump 13 connected via pipelines 14 to liquid heat exchangers 15 of the panel and a cooling unit 16.

The power supply to the thermoelectric batteries of the panel and the cooling unit is supplied from the DC generator 17 through the PU; 1T 18 of the control. The air temperature is monitored using sensor 19, the panel temperature is controlled by sensor 20. The device is turned on using the control panel 18.

The installation works as follows.

With minor thermal loads, the following modes are possible: radiation, in which power is supplied only to thermoelectric panels 5 batteries; convective - thermoelectric batteries of the cooling unit 4 and ventilation are working, in which all thermopiles are disconnected. At highest heat load915

It is possible to use a radiation-convection mode on the vehicle cabin, which is a combination of cooled cabin ventilation

air and radiation cooling.

In this mode, power from the 17 pct generator is supplied to the thermoelectric batteries 5 of the panel and the heating and cooling unit 4. The air that has passed through the heating and cooling unit 4, filter 11, is supplied by the fan 10 through the air duct 3 to the air channels 2 of the panel and through the distribution nozzles 9 is directed to the working area of the cabin.

The installation during the cold period of the year with the help of the control panel 18 is transferred to the heating mode by changing the pat tern of the current supplying the thermopile 5 of the panel and the unit 4. Liquid is drained from the

heat is removed and the power supply from the pump 13 is disconnected. In this case, thermopiles operate as electric heaters.
