Computer Room Evaporative Cooling (CREC) Calculator

Adjust the editable figures below to best meet your requirements and click Calculate to assess the number of Evaporative Cooling Units you would need and the approximate savings you would make as compared to a conventional Refrigeration based system.

SERVER ROOM REQUIREMENTS
Cooling Demand	kW	Enter the total IT load
Δt through Server	C	A typical 1U server has a ΔT of 10C, blade servers go up to 15C. This is used to calculate the total flow of air. Normally use 10C
Mass flow rate Kg/s	2.5 Kg/s
Air Flow Rate	2.1 m³/s

	Refrigeration	EcoCooling
Coefficient of performance		23.8	The Coefficient of Performance (COP) of computer room equipment varies. The very best CRAC's with full free cooling options and variable speed fans operate at a COP of ~3.7. In reality most 'good' systems achieve a COP of ~2.0. Many sites put as much energy into their cooling systems as they put into their IT equipment meaning the true COP is 1.0.
Fridge Electricity Use	12.5	0 kW
EcoCooler Fan Power		kW/m³/s	An EcoCooler produces 3m³/s of air using 1.5kW of electicity
True Coefficient of performance	2.0	23.8
Total Electricity Usage	12.5	1.1 kW
	100%	8.1%
Annual Usage
Annual Running Hours			24hrs x 365 days
	Refrigeration	Ecocooling	SAVINGS
Electricity Consumption	109500	9198
Electricity Cost	p/kWhr
Total Operating Cost	£10,950	£919.1	£10,030.1
Carbon Dioxide Impact	58.1	4.1	53.1 tonnes
	0.53702 kg/kWhr Carbon Dioxide UK value

RESULTS

Savings	Cost	Carbon
Annual	£10,030.1	53.1 tonnes
5 Year	£50,151	269.1 tonnes

EcoCoolers
Flow Rate	m³/hr	This is dependent upon the EcoCooler type and the ductwork or air distribution resistance.
Number Required	0.8
Design Number Required	1
Redundancy		This is the design redundancy or resilience required of the system.
Net Requirements	2
