Precision Air Conditioning -V Dimensional & Installation Data POSITIONING Standard Front Return (1) (2) The unit is designed for use with either ducted discharge or a plenum. If neither is used, protection from rotating parts in the form of a grille must be used on the discharge air outlet. Placing objects near an unguarded fan may cause injury.
Precision Air Conditioning -V Controls GENERAL GENERAL As standard the units are supplied with an connected to a 4x20 back-lit LCD display keypad. microprocessor controller The microprocessor controller can be linked together locally to provide run/standby operation. Windows based supervisor software is also available for local or remote networking. This modular approach provides great flexibility while at the same time reducing installation and maintenance costs.
Precision Air Conditioning -V Controls STANDARD FEATURES The default screen shows the unit status and room condition (°C/RH %) without the need for interrogation and an easy to navigate menu structure for further interrogation and adjustment. Password Protection The control system integrity can be maintained by restricting access with a password PIN number. CAUTION IMPORTANT: To change the PIN number; please contact Airedale at time of order with the preferred 4 digit number.
-V Precision Air Conditioning Controls GENERAL STANDARD FEATURES Duty/Standby Operation The controller enables units to operate in run/standby mode, with up to 6 units networked together, without the need for additional hardware or controllers. Standby units can be configured to start when the run unit has a critical alarm and/or a high/low return air temperature alarm. Duty Rotation Networked units can be configured to duty rotate, providing equal hours run of fans and compressors.
Precision Air Conditioning -V Sound Measurement Method MEASUREMENT OF SOUND DATA All Sound Power Levels quoted are calculated from measured sound intensity according to BS EN ISO9614 Part 1 : 1995. SEMI HEMISPHERICAL Sound Pressure Levels are calculated from sound power using the semi-hemispherical method where the noise source is in junction with 2 boundaries i.e. the floor and 1 wall.
Precision Air Conditioning -V Design Features & Information Thermostatic Expansion Whilst offering versatile control at the full design duty of the unit, TEVs do not automatically optimise themselves to all operating conditions. Therefore, if the Valves (TEV) refrigeration system is operating at 40% or 50% of full load, especially at a lower ambient temperature than that for which the valve was sized, the conventional TEV must have the design head pressure available to ensure good refrigerant control.
Precision Air Conditioning -V Design Features & Information CONDENSATE PUMP (OPTIONAL EXTRA) The following illustrates the TOTAL static (head) pressure available. The system horizontal pipe losses and vertical lift should be factored in when calculating the condensate pump performance.
Precision Air Conditioning -V Design Features & Information Controlled by the microprocessor, electronic expansion valves are unlike their conventional thermostatic counterparts in that they can modulate independently of controller to the suction line temperature. This unique feature allows the (Only available with raise the superheat set-point, in turn dropping the evaporating temperature to a point at Electronic Expansion Valves which considerable de-humidification takes place.
Precision Air Conditioning -V Design Features & Information HUMIDIFICATION In a humidifier with electrodes, steam is produced by passing a current between electrode plates to generate heat. The higher the current being passed between the electrodes, the greater the quantity of steam that is produced. To modulate the rate of steam production, this system varies the level of water within the cylinder, thereby increasing the immersion level of the electrodes and the current being passed between them.
