1 General

1.1 Purpose

This specification is to define the basic engineering design data for use in the HVAC

system of the ITR of the Phase lll Development Project in Shanayel, comprising the general

requirements to be complied with in the project and a descriptive system.

The air conditioning systems are intended to ensure appropriate conditions for occupants

and equipment, through the cooling indoor air.

2 Description and System Operation of Air Conditioning System

It is about an installation designed to cool the air with operation 24 hours per day, in an ITR.

The system will consist of single packaged air ACCU with high-capacity, mini split type, two

effective and two redundant. They will attend the entire area of the ITR.

It will be used as refrigerant R-410A and equipment operation will be cooling only. The ACCU

will be air-cooled, with direct expansion and will have a redundancy level (2x50%). The ACCU

will be installed internally on an appropriate basis. The air conditioning system will have a local

control panel.

The temperature control will be performed by a remote controller, with signals from temperature

sensors installed in the environment.

The HCP will provide the power control and the automation control of the ACCU. In case of fire

accident, the HVAC systems will automatically turn off. The actuation of the smoke detectors

shall result the HVAC operation in recirculation mode.

3 Design Criteria

Humidity, Over Pressure and Fresh air flow are not requirement for the ITR.

3.1 External Conditions

Design temperature


8/14



Doc. No. : 44-21-39-3602 Page 5 of 11

- Summer : 48℃ db / 30℃ wb

- Winter : 6℃ db – HR 90%

- Outdoor daily range : 15℃

- Summer ambient temperature for selection of external units : 52℃

The HVAC equipment will be selected to provide a down grated cooling capacity at maximum

outdoor dry bulb temperature (DBT) of 46 ℃ on condenser side.

3.2 Indoor Conditions

Design temperature

- Summer required temperature : 25℃

- Winter required temperature : 20℃

3.3 Heat Dissipation & Safety Factor

The calculation of the heat dissipation and the overall balance for the ITR will be done

taking into account :

44-21-40-3610_POWER CONSUMPTION & HEAT DISSIPATION – OSBL_RevD ;

Latent and sensible heat gains due to people (0 people per ITR) ;

External heat losses due to Solar radiations, walls, ceiling and floor transmissions ;

Additionally, the cooling load calculation includes a 15% safety factor.
