Description

CLIMATE INSTALLATION OF THE CAR.

The utility model relates to the field of transport engineering, namely to the ventilation system, heating and air conditioning of the cabin, as well as the creation of comfortable conditions in vehicles, such as cars.

The technical solution of the heating and ventilation system of the VAZ-2110 automobile (prototype - “Spare parts catalog VAZ-2110, 2111, 2112, publishing house“ Wheel, Moscow, 2000, p. 127), containing the air intake block with openings for air intake, in which there is a cooling unit with pipelines for the circulation of coolant and a condensate drain pipe, and a heater block with a fan, piping and openings for air to enter the passenger compartment. The blocks are rigidly interconnected and are made in one solid case.

The disadvantage of this system is the limited ability to upgrade the installation associated with binding dimensions in the housing

installations, for example for a cooling unit. The location of the fan in the heater unit suggests increased resistance to air at the inlet to it in the form of an air conditioner evaporator and air intake channels.

Centrifugal fans operate less efficiently with increased inlet air resistance.

The objective of this utility model is aimed at improving consumer properties, increasing the efficiency of the system and ease of packaging with the ability to complete the system with various modifications.

To solve this problem, a car air conditioning system is proposed, containing three blocks: an air intake block, a cooling block, and a heater block. The execution of blocks by separate nodes allows you to assemble the installation in various configurations, for example, with or without air conditioning. In the first case, the climate system is obtained, and in the second, the ventilation and heating system.

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

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

The essence of the technical solution is illustrated in the drawing. Figure 1 - General view of the air conditioning system; Figure 2 is a rear view from the side of the canot; Fig.Z is a general view with an intermediate air duct.

The climate control unit of the car contains three units made up of separate units and joined together: an intake unit (1), a cooling unit (2), and a heater unit (3). The air intake block (1) is made with holes (4) for air intake, one of which has an air filter (5). A hole with a filter (5) is placed under the hood where air is taken from the outside of the cabin and filtered. In block (1) there is a fan (6) for supplying air with an electric motor (7) located at the bottom of the block. Installing a fan (6) in the block (1) of the air intake at the air inlet to the climate system allows you to effectively realize its capabilities. The cooling unit (2) contains an air conditioning evaporator (not shown) assembled with pipelines (8) for circulation of the coolant and a pipe (9) for draining the condensate. The heater block (3) is made of at least two half-shells with pipelines (10) that conduct air through a radiator (not shown) or bypassing it, has openings for air to enter the passenger compartment: hole (11) for blowing the windshield, hole (12) to the ventilation nozzles, openings (13) for blowing the feet of the driver and passengers. At least two distribution and supply flaps (14) are used to adjust the ratio of the amount of air entering each outlet opening. Each

the unit is connected in series in the installation: air intake unit, cooling unit, heater unit. For ease of installation in a vehicle, the heater unit (3) and the cooling unit (2) can be pre-assembled into a single unit, and the air intake unit (1) can be mounted separately from the engine compartment of the vehicle. This air conditioning system allows you to exclude or replace the cooling unit with an intermediate air duct (15), which allows you to modify the air conditioning system according to the wishes of the manufacturer or consumer.

Claims (2)

1. Car air conditioning system, comprising an air intake unit with openings for air intake and a cooling unit with pipelines for circulating coolant and a condensate drain pipe, a heater unit with openings for air outlet into the car interior, a fan, characterized in that the air conditioning system contains at least three units, each of which is made by a separate unit with the possibility of eliminating or replacing the cooling unit with an intermediate air duct, and the fan is located in the air intake unit. 2. Climatic installation of a car according to claim 1, characterized in that the air intake unit has an air filter.
