An object of the present invention is to provide an air conditioner for a rail vehicle that is excellent in cleanliness and comfort by cleaning the air conditioner at an appropriate timing without causing discomfort to passengers. An air conditioner for a rail vehicle including a vehicle control system includes: a refrigeration cycle device 3 that can execute a cleaning operation; and an air conditioning control device 4 that controls the refrigeration cycle device, and the air conditioning control device 4 can communicate with the vehicle control system 2 and causes the refrigeration cycle device 3 to execute a cleaning operation on the basis of status information obtained from the vehicle control system 2.

A rail car air-conditioning device is equipped with: a refrigerant circuit that has a compressor and an outdoor heat exchanger; an outdoor blower; a compressor operation frequency deriver that derives a compressor operation frequency of the compressor on the basis of a rail car interior setting temperature and a rail car interior temperature; an inverter for compressor use that drives the compressor at the compressor operation frequency; an outdoor blower operation frequency deriver that, in accordance with a predetermined correspondence relationship, derives a blower operation frequency of the outdoor blower corresponding to the compressor operation frequency; and an inverter for outdoor blower use that drives the outdoor blower at the blower operation frequency. The outdoor blower operation frequency deriver has a highly energy efficient energy-saving mode and a low-energy efficiency low-noise mode, and can switch between the energy-saving mode and the low-noise mode.

A compressor module, as a component of a refrigerant cycle device, is attached to a casing that houses a refrigeration cycle device. The compressor module includes a compressor that compresses refrigerant, a supporting member that supports the compressor, a vibration-reducing rubber body that is attached to the supporting member, ancillary equipment that is added to the compressor, a base supporting the supporting member via the vibration-reducing rubber body and supporting the ancillary equipment with a portion of the base other than the portion supporting the supporting member.

An air handling system (1) for a land transport vehicle, in particular a railway vehicle (M) is disclosed. The system includes: one or more air handling units (2) distributed within the vehicle (M); a cooling machine (4) that supplies frigories to the air handling units; and a frigories storage unit (8) that is capable of being loaded by the cooling machine and of supplying frigories to the air handling units when the vehicle is travelling in an enclosed or partially enclosed space. When the vehicle (M) is travelling in the open air, the cooling machine (4) supplies frigories to the air handling units (2) and loads the frigories storage unit (8) if a surplus of frigories is produced, by discharging into the exterior of the vehicle (M) the heat extracted from an interior volume of the vehicle.
