Description

The utility model relates to the field of transport engineering, namely to ventilation, heating and air conditioning of the passenger compartment and the creation of comfortable conditions in the car.

A known vehicle heating and ventilation system (prototype - certificate of the Russian Federation No. 24151, class B 60 N 1/24, 1/26, priority date 01/28/2002), which contains an air intake with a fan and an air purification filter connected to the heater having a system of dampers for controlling and distributing air flows with mechanical drives, which is adjacent to an extensive system of heating and ventilation air ducts, on the end parts of which there are guide nozzles. A disadvantage of the known technical solution is the lack of air conditioning in the cabin, which leads to a decrease in consumer millet.

The objective of this utility model is aimed at ensuring the maintenance of a predetermined temperature in the passenger compartment of a vehicle in all weather conditions and increasing consumer demand for air-conditioned cars.

To solve this problem, a passenger car climate system is proposed, equipped with an air conditioning device and comprising a cooling unit, docked on one side with an air intake including a fan and an air purification filter, and on the other hand with a heater having a system of control and distribution airflow flaps with mechanical drives , which adjoins a branched system of heating and ventilation ducts, on the end parts of which there are guide nozzles . In the cooling unit, a condensate drainage device is made and an evaporator with a thermostatic valve, a surface temperature sensor for the evaporator are located.

Comparison of the claimed technical solution with the prior art in scientific, technical and patent documentation as of the priority date in the main and related sections shows that the set of essential features of the claimed solution was not known - therefore, it meets the patentability condition of “novelty”.

The proposed technical solution is industrially applicable, because can be manufactured industrially, efficiently, reproducibly, therefore, meets the patentability condition “industrial applicability”.

The essence of the technical solution is illustrated in the drawings.

The climatic system of the vehicle is a heating, ventilation and air conditioning system designed to distribute and distribute air through the passenger compartment in the heating, ventilation and air conditioning mode of the passenger compartment, and create comfortable conditions in the passenger compartment.

The climatic system of the vehicle includes a heater (1) connected to the air duct (2) for heating the windshield. Left (3) and right (4) side-window heating ducts are installed on the air duct (2), respectively, with nozzles (5.6) at the ends and fixed to the instrument panel (not shown).

The air ducts (7, 8) of the body ventilation are joined with the intermediate housing (9), the outlet of which is connected to the side nozzles (10, 11), which are also fixed on the instrument panel. The central nozzle (12) for ventilation of the body is used for ventilation at the level of the head of the driver and front passenger, it is also attached to the instrument panel and docked with the intermediate housing (9). The air ducts for heating the legs of the driver (13) and the legs of the front passenger (14) are made in the heater body (1). Air ducts (15, 16) for heating the feet of passengers in the rear of the passenger compartment are interconnected and with a heater (1). The cooling unit (17) adjoins the heater (1), in which the evaporator with thermostatic is located

valve (not shown), and in the lower part of the block is a condensate drainage device (18). The cooling unit (17), on the other hand, is adjoined by an air intake (19) with a fan (20) and an air filter (21).

The evaporator with a thermostatic valve located in the cooling unit is connected by pipelines (22, 23, 24) through the receiver-dryer (25) with a condenser (26) on the one hand and through the compressor (27) on the other, forming a closed loop. The control unit (28) with mechanical actuators (29) of the control and air flow dampers. The design of the climate system involves the execution of the drive of the heater control damper by an electric motor reducer (30).

The climate system works as follows. With the fan (20) of the air intake (19), outside air is taken through the filter (21), where it is cleaned, or the air from the passenger compartment and fed through the cooling unit (17) to the heater (1) of the climate system. Moreover, in the air-conditioning (cooling) mode when the compressor (27) is turned on, the air washes the fins of the evaporator and cools, and in the ventilation or heating mode, when the compressor is off and there is no heat removal by the evaporator, the outside air enters the heater without changing the temperature and humidity. In the heater (1), the control damper air is directed in the heating mode through the radiator or, in the ventilation mode of the vehicle interior, as well as air conditioning bypassing it, into the system

air ducts using air distribution dampers. The control unit (28) with mechanical drives or with the help of an electric motor reducer (30) allows you to control the climate system and the optimal distribution of air flows in the cabin through the air duct system (2, 3, 4, 7, 8, 9, 13, 14, 15, 16 ) In addition, by cooling the air with high humidity first in the cooling unit and removing condensing moisture through the condensate drain 918), and then heating it in the heater, the climate system allows for the dehumidification of the air supplied to the passenger compartment and to regulate the humidity in the passenger compartment.

The inventive climate system of ventilation, heating and air conditioning provides uniform distribution, wiring and regulation of air flows in the passenger compartment, increases the efficiency of the system as a whole.
