Embodiment Construction

[0032] [32] If figure 1 As shown, a passenger rail vehicle 2 has a passenger compartment 4 defined by side surfaces 6 , a floor 8 and a roof 10 .

[0033] [33] In the remainder of this specification, the "top" of the compartment refers to the compartment space located near the roof 10 , while the "bottom" of the compartment refers to the compartment space located near the floor 8 .

[0034] [34] The vehicle 2 has an air conditioning system 12 for the passenger compartment 4, the air conditioning system comprising: an air conditioning unit 14 for generating cooled air or heated air; the air generated by the air conditioning unit 14 is distributed to the bottom of the compartment 4 and a second net 18 that distributes the air generated by the air conditioning unit 14 to the roof of the cabin 4 .

[0035] [35] The air conditioning unit 14 includes: a main air handling unit 20 for air heating or cooling; a set of powered fan units (GMV) 22 for forcing airflow through the air hand...

Abstract

The invention discloses an air conditioning system of a rail vehicle carriage, a corresponding rail vehicle carriage and an air conditioning method. The air conditioning system comprises air processing devices (20, 28) for heating and/or cooling air; a first net (16) for delivering air to the carriage bottom, and a second net (18) for delivering air to the carriage bottom. According to one aspectof the invention, the air processing devices (20, 28) are arranged to deliver a first air flow (F1) and a second flow (F2) with different temperatures through the first net (16) and the second net (18).

Description

technical field [0001] [01] The present invention relates to an air-conditioning system for a vehicle compartment, an air-conditioning system of this type comprising: [0002] [02] Air handling units for heating and / or cooling air; [0003] [03] a first net for distributing air to the bottom of the compartment, and [0004] [04] A second net for distributing air to the roof of the cabin. Background technique [0005] [05] Document EP 1 442 954 A1 describes an air-conditioning system for railway vehicles of the aforementioned type, which comprises distribution means for distributing the treated air towards a first net or a second net, in order to distribute more Air is supplied to the top of the compartment or more air is supplied to the bottom of the compartment. [0006] [06] Of course, such a system cannot maintain the temperature with a controlled temperature gradient between the top and bottom of the railroad car cars, and thus cannot guarantee a satisfactory level of...
