Abstract
A compression-type air-conditioning system for a railraod car, intended in particular for a high-speed train, includes a refrigerant compressor, a condenser with tubes in which compressed fluid is cooled by circulation of air around the tubes and is thereafter liquified, an expansion valve supplying a low-temperature refrigerating gas, and an evaporator following the expansion valve. The tubes of the condenser form an oblique bank between a floor of the railroad car and an underframe of the air-conditioning system. The oblique bank enables, on the one hand, the number of the tubes and consequently the cooling capacity of the air-conditioning system to be increased. On the other hand, space is freed up in a vertical direction for fitting damping devices at different fastening points on the condenser. As a result of the invention, there is an improvement in the comfort of passengers, both in terms of air-conditioning and in terms of reducing vibrations. Furthermore, there is a reduction in operating costs.
