Close Control Air Conditioning
This Certification Programme applies to factory-made units intended for Close Control Air Conditioning. This programme includes units with cooling capacities up to 100 kW under the specified test conditions. Participating companies must certify all production models within the scope of the programme.
2.1 Direct expansion close control air conditioner
Unit containing complete refrigeration system, designed to satisfy the requirements of the process carried out in the conditioned enclosure.
2.2 Chilled water close control air conditioner
Factory built assembly designed to satisfy requirements of the process carried out in the conditioned enclosure; it is connected to a chilled fluid generator which contains a refrigeration circuit.
2.3 Total cooling capacity
Heat removed by the air conditioner from air within a defined interval of time.
2.4 Sensible cooling capacity
Capacity of the unit for removing sensible heat from the evaporator intake air.
2.5 A-weighted sound power
A single figure on a specific scale which can be related to the subjective assessment of the loudness of a noise.
2.6 Effective power input
Average electrical power input to the unit obtained from:
- the power input for operation of the compressor and any power input for defrosting excluding additional electrical heating devices not used for defrosting
- the power input of all control and safety devices of the unit
- the proportional power input of the conveying devices (e.g., fans, pumps) for ensuring the transport of the heat transfer media inside the air conditioner
