METHOD OF AND AIR CONDITIONING SYSTEM FOR INDIVIDUAL CONTROL OF AIR TEMPERATURE IN COMPARTMENTS OF PASSENGER CAR (VERSIONS) Russian patent published in 2006 - IPC B61D27/00 B60H1/00 

FIELD: railway transport; passenger car air conditioning systems.

SUBSTANCE: invention is designed to provide comfort conditions for passengers of railway cars. According to proposed method, outside and recirculation air is taken in, and outside or mixture of outside and recirculation air is separately processed and delivered into central induced air duct with outlets in each car compartment, and only recirculation air is processed. Control of flow rate of recirculation air is provided by setter depending on temperature of air in compartment. To provide constant consumption of recirculation air in outlets of other compartments, constant static pressure is maintained in recirculation air delivery air duct controlled by static pressure sensor. Passenger car air conditioning system includes monoblock air conditioner containing cooling machine, outside and recirculation air suction branch pipes and two branch pipes for delivering outside and recirculation air processed in air conditioner into two central air ducts with one unit for distributing air between compartments. Each unit for distributing air between compartments is provided additionally with air ducts for partial bypassing of recirculation air into car passage. System is furnished additionally with recirculation air duct placed along car and connected with air ducts for partial bypassing of recirculation air and with recirculation air branch pipes of air conditioner.

EFFECT: provision of individual control of air temperature in each compartment of passenger car at preservation of uniform distribution of air along line of recirculation air duct.
