Abstract

SUMMARY OF THE INVENTION; air is supplied from the body to the air conditioning device and cooled. The streams of treated air are distributed under the ceiling from top to bottom along the middle of the van along its entire length. The air is removed on both sides of its distribution in the immediate vicinity of the last of the streams, which are laid upwards on the walls of the box body. The air handling unit is in communication with a distribution duct located under the ceiling along the middle of the van along its entire length. The unit is connected with intake ducts with overlapping ventilation adjustable grilles. Intake ducts are located under the ceiling on both sides of the distribution duct, in the immediate vicinity. 1 s.p., f-ly, 3 ill.

Description

The invention relates to ventilation and air conditioning in vehicles, mainly in box bodies.

The purpose of the invention is to reduce energy costs and improve working conditions while improving the thermal regime of the equipment.

In FIG. 1 shows a ventilation system for implementing the inventive method of ventilating a vehicle; figure 2 - cross section aa in fig. 1; on figs - section BB in fig. 1.

A ventilation system for implementing a method of ventilating a vehicle, preferably a van body, having a working compartment 1 with control panels 2 located therein.

apparatus and other equipment with insignificant heat dissipation and the technical compartment 3 with increased heat dissipation from equipment 4, contains an air treatment unit 5 (for example, used for processing a refrigeration machine) located outside the box body, a distribution duct 6 and intake ducts 7 with a valve adjustable grilles 8, respectively overlapped holes for the distribution and intake of air from the body, located in the upper part of the body and separated by longitudinal spans Horns 9c with thermal insulation. Between the lower 10, side 11 surfaces of the body fences and the lower 12, rear 13 walls of the equipment 2, 4

channels 14 for drawing air from the body are formed. In the upper areas of the body, channels 14 are created by installing additional decorative heat-insulated partitions 15 with a gap along the fence.

The ventilation system for implementing the vehicle ventilation method operates as follows.

Cooked (chilled, heated, moistened or drained) by mouth. The air is supplied through the distribution duct 6 through adjustable grilles 8 into the working 1 and technical 3 compartments from top to bottom, while blowing the equipment 2 and 4 and maintenance personnel with jets with the corresponding ejection ability. The supply air temperature rises along the distribution path, and in technical screening 3 more than in the working compartment 1. The heated air in the body compartments is laid on the floor fencing, unfolds and streams from bottom to top on the walls of the box body through channels 14 to exhaust ducts 7, while increasing its temperature when blowing the rear walls of equipment 2 and 4. In the technical compartment 3, the temperature of the exhaust air may exceed the ambient air temperature when operating the body in-vans during the warm season. Through openings covered by adjustable ventilation grilles 8, air enters the intake ducts 7 and through them into the air treatment unit 5. for subsequent processing. After air treatment in unit 5, the process of cooling and ventilation of the box body with the equipment is repeated. . . By adjusting the ventilation grates 8 of the amount of air removed from the compartments 1 and 3 or individual zones of the room, mixing of air flows with different temperatures is achieved both in the room itself and in the channels 14 along the fence; an increase in air temperature near individual sections of the enclosures or equalization in temperature of the removed flows in the channels 14; a change in the temperature perapad between the air in the channels 14 and the environment both in separate sections of the fences and throughout them, which as a whole makes it possible to reduce the energy consumption for maintaining the temperature and humidity conditions in vehicles, mainly in van bodies. Flooding of the working area. Supply air with the possibility of

regulation of the ejection ability of its flows provides standardized working conditions in the workplace,

Removing air from the wagon

both sides of the place of its distribution, flowing from bottom to top on the walls of the wagon body, eliminates stagnant zones near equipment 2 and 4 and allows ventilation from all sides,

Claims (3)

thereby improving its thermal regime. SUMMARY OF THE INVENTION 1. A method of ventilating a vehicle, preferably a van body, comprising a working compartment with heat dissipation and a technical compartment with increased heat dissipation from the equipment, including supplying air from the body to the air conditioning devices, cooling and subsequent distribution flows of treated air from the ceiling from top to bottom along the middle of the van along its entire length, characterized in that, in order to reduce energy costs and improve working conditions at the same time Variable thermal improvement of equipment, air removal is carried out on both sides of the place of its distribution in the immediate vicinity of the last of the streams, which are laid upward on the walls of the box body. 2. The ventilation system of the vehicle, mainly a box body containing a working compartment with heat and a technical compartment with increased heat emissions from the equipment, an air treatment unit connected to a distribution duct located under the ceiling along the middle of the van throughout its length, and with an intake duct with overlapping adjustable ventilation grilles, and the fact that, in order to reduce energy costs and improve working conditions while improving the thermal regime of the equipment, the system additionally contains an intake duct with overlapping adjustable ventilation grilles, while the intake ducts are located under the ceiling on both sides of the distribution duct in the immediate vicinity of the latter. 3. The system according to claim 2, characterized in that the intake and distribution ducts are made in the form of a common duct, separated by longitudinal partitions with thermal insulation. 5 .. 7 & "5 3 4 , I {phoF.  ° d ° d yes tg / up :.-i-lЈ 3: to. l I: .I. - /} b 71 7
