For 50HH01A/B calcualation:As per article 10: No heaters were added due to the assumption that at
least 50% of internal load are available at all timesAs per heat dissipation load: total load is 4789W (from CCR) + 21718W(From IER).
As per calculation, re-heat coil load is 5.6kW for zone 1 (CCR) and19.2kW for zone 2 (IER)Following the calculation, heaters must be required. But vendor confirmNo heaters were addedVendor to clarify

1. GENERAL
1.1. Background
Thien Ung field is located in the middle part of Block 04-3 in the Nam Con Son Basin, offshore
the Socialist Republic of Vietnam, approximately 15 km of Dai Hung field, and approximately270 km southeast of Vung Tau. The Block 04-3 covers an area of approximately 2600 km2. The
Thien Ung field is including its 2 structural parts. Thien Ung structure discovery was made in
2004 with the 04- 3-TU-1X well. Two subsequent appraisal wells (04.3-TU-2X and 04.3-TU-3X),
drilled and tested respectively, delineated the field.
Location of Thien Ung field is shown in Figure 1.1 below.
Figure 1.1: Thien Ung Reservoir Location
1.2. Purpose of document
This document is to define the required capacity for the HVAC systems. It will be use as a basisfor equipment sizing, duct sizing as well as electrical and other utilities consumption requirement.
This calculation utilizes the Carrier E-20 HAP software which heat load analysis is based on
the ASHRAE transfer function method for load calculations and detailed 8760 hour-by-hour
simulation techniques for the energy analysis.

3. DESIGN BASIS
A minimum of 800 l/s of fresh air are introduced into the system to provide pressurization. These
amounts are generally sufficient to cater for leakages and also providing fresh air for the
personnel. Except for Battery room where the amount of fresh air will have to replace the air
exhausted out where 100% fresh air will be supplied.
A minimum of 50% electrical loads are assumed to be working at all time. No heater will
be provided if the heating requirement is less than 50% of internal loads.
An additional safety factor of 10 % (sensible) and 10 % (latent) heat gain shall be provided in
this calculation.
Values used for solar heat gain are based on peak hour periods.
Internal loads used are assumed to occur or coincided at the peak load condition. Sensible and
latent heat gain for peoples shall be included in this heat load calculation.
Bypass factor (BF) used for the cooling coil is 0.10 and is industry standard for typical comfort
application.
Winter design heating calculation was done to give the required heater capacity during
the minimum temperature condition. The calculation will provide the heater size when there is
no space load on the system. The given heater size will maintain design temperature and
humidity range.
Part load condition may also be calculated from Air System Design Load Summary Table.
The heat gain estimation from lighting is considered in this calculation. Lighting power densities
is 20W/m2.

Fresh air requirement for HVAC system shall be the greater value of the following two criteria:
Total fresh air required per standard (The fresh air supply shall be 8.5 liters per second per
occupant for manned areas).
Fresh air requirement as total exhaust air (mechanical exhaust air plus leakages) for pressure
room >0Pa.
Fresh air requirement as total exhaust air (mechanical exhaust air except infiltration air) for
pressure room

Note:
1. Total outdoor air required shall be based on fresh air required for human.
Reference from ASHRAE standard 62.1-2010 "Ventilation for Acceptable Indoor Air Quality",
Table 6.1: Minimum Ventilation Rates in Breathing Zone.
2. Leakage area required shall be based on area of door, wall, floor and roof.
- 2001 ASHRAE Handbook - HVAC Fundamentais, Chapter 26 - Ventilation and Infiltration.
- 2007 ASHRAE Handbook - HVAC Applications, Chapter 52 - Fire and Smoke Management.
3. Required ventilation air shall be based on either directly exhaust air plus exfiltration air or outdoor air required based on ASHRAE
standard 62.1-2010 requirement, whichever is higher.
4. Conditioned supply air shall be selected based on minimum required air change per hour per room or calculated airflow based on
heat load requirements, whichever is higher.
5. Ventilation for Battery room based on below equation (EN 50272-2):
Flow rates (m3/h) = 0.05 m3/Ah * n * Igas (mA/Ah) * Crt (Ah) *10-3
n = 364 cells- number of cells
Igas = 8 mA/Ah - Current producing gas
Crt = 1200 Ah - Rated capacity
6. Number of Air Change per Hour is selected based on Ashrae Application 2007
7. Abbreviations:
AC - AIR CONDITIONED
MV - MECHANICAL VENTILATION
ACH - AIR CHANGE PER HOUR
OA - OUTDOOR AIR8. Formula for calculating flow rate based on number of Air Change per Hour:
Flow rates (L/s) = Room volume (m3) * ACH/3.6
9. Formula for calculating flow rate based on sensible heat gains from equipment loads
Flow rates (L/s) = Sensible load (W) / {Specific heat (kJ/kg.K) * Density (kg/m3) * Delta T (K)}
Specific heat = 1.007 kJ/kg.K at 41.5 deg. C
Density = 1.122 kg/m3at 41.5 deg. C and 98% RH
Delta T = 5(K), Design room max. 44 deg. C (Ventilation only).

10. CONCLUSION
Equipment shall be sized to maximum ambient condition of 39 C and minimum ambient of
21 C. No heaters were added due to the assumption that at least 50% of internal load are
available at all times. The result shows that the amount of re-heat requirement for
humidity/temperature control are less than the available internal heat load.
