Benefits

• Variable speed
• Low power consumption
• Saves on OPEX

Overview:

It is proposed for BTS sites where the acceptable inside temperature is 50 Deg C. The Design is suitable for various combinations of equipment’s within a shelter.

Solution Description:

The Ventilation system will have main components Fan Out unit , Filter Unit and Controller unit. Filter unit to be placed on lower level w. r. t. floor preferably at door. Fan outlet unit should be placed on height closer to roof of shelter on diagonally opposite wall. Ensure that the Fan Unit is installed as possible near to BTS so as hot air gets directly escaped to atmosphere. Micro-controller with in-built intelligent logic is able to ON/OFF and control the speed of fan and ON/OFF upto 2 air-conditioners based on the Ambient and Shelter Temperature thereby air-conditioner run hours is reduced and bringing energy savings.

Controller Features:

• Equal run Hour for both AC
• In Case AC 1 fail auto switch to other AC
• Both AC fail auto switch to Emergency cooling
• Display of FCU run hour
• Display of FCU count
• Display of AC1 and AC2 run hour
• Controller can operate on 230 Vac. Incase Grid fail auto switch to 48VDC
• Dual Display
• Auto fan speed reduction in case of lower ambient to save energy
• 10.DC voltage Protection -In case DC battery voltage goes very low/High FCU shuts off
• 11.Emergency cooling in case Aircon cooling fail/ Grid voltage lose/over/under voltage
• 12.LED display indication and PFC alarm in case failure to fan/ sensor /HT
• 13.All operational details are displayed on controller Box itself
