Indirect outdoor air conditioning unit

Published on : Tuesday 30-11--0001

Features

• Energy savings and carbon dioxide reduction throughout the year (coefficient of performance (COP) 10, annual average, in Tokyo)
• There is no concern about mixing in contamination from the outside (PM 2.5), SOx, NOx, etc. because indirect outdoor air cooling is performed without directly introducing the outdoor air.
• The required utility is only a power supply (no chilled water, no cooling water are required).
• Heat generation from the servers is handled using a heat exchanger indirectly with an outdoor air cooling system and a cooling system with heat pump type refrigeration.

(Air cooling + refrigerant system)

In winter, only the outside air is used, and in between seasons and in summer, the use of the outdoor air plus refrigeration reduces the annual electricity consumption.

When operating at a cooling capacity of 40 kW throughout the year:

• About 1,230,000 yen in electricity charges per unit can be reduced.
• About 36 tons of carbon dioxide per unit can be reduced

Conditions:

Cooling capacity: 40 kW, supplied air (SA) temperature: 26°C, supplied air (SA) volume: 8500 m3/ h, at average temperature in Tokyo, coefficient of performance (COP) of the general air conditioner compared = 3.5, electricity charges: 19 Yen / kWh, carbon dioxide consumption unit: 0.55 kg - CO2 / kWh.

Application example

Type of data center

F-COOL NEO is the ideal air conditioner for data centers that require cooling air conditioning with clean air throughout the year, as well as in the precision processing and food chemistry fields.

 

It is used in Food and Chemical industry.
