Air-conditioning systems for data centers are designed for year-round cooling with very high cooling intensity per square foot of floor area. The high sensitivity of electronic components in such facilities requires that temperature, humidity, air movement and air cleanliness must be kept consistent and within specific limits to prevent premature equipment failures and costly downtime. Refrigeration and Air Conditioning requires a variety of skills in mechanical systems, electrical/electronic systems and systems troubleshooting. Learners will understand and practice safe procedures to comply with the Occupational Health & Safety handbook and WHMIS procedures.

From 2015, it will be illegal to use Hydrochlorofluorocarbons ( HCFCs ), including the ozone-depleting refrigerant gas R22, in refrigeration, heat pump and air conditioning (AC) systems. R22 is commonly used in AC systems pre-dating 2004 and so its ban will have a major effect on air-conditioning costs.
