FAQs - Air Conditioning

Air conditioning sizing, installation, maintenance and energy efficiency.

The Energy Efficiency Ratio (EER) is the rate of efficiency of the mechanical chilling systems and indicates the ratio of cooling capacity (measured in kW) to the power input (measured in kW). The higher the EER the more efficient the air conditioner. The Energy Efficiency Ratio cannot always be used to make a comparison between air conditioner manufacturers as some use ‘total’ cooling capacity as their reference point and others ‘sensible’ cooling capacity.

Cooling capacity is the extent to which an air conditioner can cool the server room or datacentre. Cooling capacity specifies the maximum amount of heat the air conditioning unit can take in and convey to the outside. Cooling capacity is measured in kilowatts (kW).

We recommend atleast two preventative maintenance visits a year for server room and datacentre air conditioners to ensure their operation is trouble free. The preventative maintenance visit will cover inspection, cleaning and consumables replacement as required.
