Unique HVAC system to keep MCC riders warm

Unique HVAC system to keep MCC riders warm
A smart heating, ventilation and air conditioning (HVAC) system will keep trains warm when stopped at stations.

Heat screens will keep Lastochka  commuter trains on the Moscow Central Circle (MCR) warm. Warm air will blow automatically in front of carriage doors when trains stop at stations. This is part of the trains’ smart HVAC system.

“Warm air is blown in front of the carriage doors, creating a heat screen and preventing cold air from entering the train,” the Russian Railways press service said.

The warm blowing air will shield riders from extreme temperature changes and will keep the trains warm when stopped at stations. Also, the doors only open by request to better control interior temperatures. Graphics remind users to push a button to enter or exit. Buttons are operational at full stops only. The button turns green when the door is ready to open.

The smart HVAC system keeps comfortable temperatures in trains all the year round. The press service explained that the heating system is activated automatically when the ambient temperature drops below interior temperatures.

Unlike commuter trains, Lastochka carriages have no vestibules. This allows riders to quickly enter and exit their compartments.

“This is particularly important for the MCR where stations are located only two or three minutes apart,” press service officials noted.

Besides, each MCR train has an air filtration system protecting riders from possible infections and viruses. The system’s filter is part of each carriage’s HVAC system, the Russian Railways press service said.

In all, 28 fast and quiet Lastochka trains can reach 120 kph on the MCR. Peak hour intervals are about six minutes, and are 11-15 minutes the rest of the day. It takes about 75 minutes to take one complete lap. The MCR was opened on 10 September, and 26 of the 31 stations, 12 with metro station changes, are now open. The other stations are to open by late October.
