# TSYS Group - HQ data center documentation - cooling
|
|
|
|
## Introduction
|
|
|
|
Cooling is a critical component of any data center. It is often the dominate consumer of energy.
|
|
|
|
We keep our data center at about 70 degrees F.
|
|
|
|
## Make / model
|
|
|
|
We have a
|
|
|
|
* HiSense Portable Air Conditioner (standalone) the manual lists several possible models, unsure which exact one we have. It was about 700.00 at Lowes with a multiple year replacement warranty.
|
|
|
|
which is rated for:
|
|
|
|
* 15,000 BTU
|
|
|
|
It draws about 7 amps when the compressor is running.
|
|
|
|
With our heat load, the compressor does cycle on/off ,so it keeps cool pretty efficiently from an energy perspective.
|
|
|
|
## Tips/tricks
|
|
|
|
* Extended exhaust house
|
|
|
|
We moved the air conditioner to the front of the racks (cold aisle) and extended the exhaust
|
|
hose todo so.
|
|
|
|
* Heat barrier
|
|
|
|
We deployed a cardboard heat barrier above the racks, to keep hot air behind the racks. We also have a vent duct (made of cardboard) to a panel we removed above the doorway.
|
|
|
|
* Insulation
|
|
|
|
* Insulate the exhaust hose!
|
|
|
|
* Air movers
|
|
* We have a tower fan in the hot row (back), pushing the heat towards the duct.
|
|
* We have two small blowers in the cold row (front) helping "kick back" the air blowing from the HiSense.
|
|
|
|
## Instrumentation
|
|
|
|
We use:
|
|
|
|
* temper usb probe
|
|
* lm-sensors
|
|
* DRAC
|
|
|
|
all consumed via SNMP by librenms to monitor/alert on temperature.This lets us find hot/cold spots across the racks and make any necessary adjustments. |
