EXECUTIVE SUMMARY

This document is submitted by Loch Harbour Group, 3060 Williams Drive, Suite 510, Fairfax, Virginia 22031, to satisfy CLIN 00100 DI-034-00 Heating, Ventilation and Air Conditioning

System Report, of Contract No. 6913G623P800007.

The purpose of this report will be to explain the level of details provided in the drawing along with the supporting calculations and representing the salient features and components of each HVAC system.

The report shall define the overall system configuration and will include preliminary supporting calculations for major system components, and system performance capability for each HVAC system in the next design phase.

Drawings have been prepared for each HVAC system identifying equipment and components, preliminary duct sizes, and material schedule for the next design phase.

The vessel shall be designed to have A1, Passenger Vessel, Great Lakes Service, Ice Class IE, AMS, HAB and COMF notations as per ABS.

Government REVIEW and COMMENT of this report is REQUIRED.

A. DESCRIPTION

Mechanical ventilation systems shall be provided in machinery spaces, crew accommodation areas, cargo areas, passenger spaces and other compartments or voids containing navigation and electronic equipment.

Individual and combined supply/exhaust fans were both incorporated in the design. Individual supply/exhaust fans were provided for the Aux machinery room, battery room, Engine room, main passenger deck 01 (level) and pilot house deck (02 level). Spaces other than those mentioned above have various combined supply/ exhaust fans based on the requirement.

The HVAC system is a multi-zone system capable of providing an adjustable range of air temperatures between 64 °F (17 °C) and 80 °F (26.5 °C). The system is split into passenger zones and crew/cargo zones. These zones shall have the ability to be segregated and allow for winterization to reduce the amount of cooling and heating load during winter lay-up months or periods without passengers and minimal crew. In all passenger accommodation and recreation spaces the temperature shall be maintained by temperature controllers. The Contractor shall be responsible for completing the detail design, final component selection and system commissioning. The installation shall be completed to the satisfaction of the NPS or their representative.

d) Passenger Lounges

e) Passenger Heads

f) Passageways

g) Guest Staterooms

h) Engineering Compartment (ECR, Workshop, Engine Room)

i) Battery Room

j) Spaces containing main and ship service switchboards, and propulsion and thruster variable speed drives and converters, if installed.

k) IT Closet and other compartments or voids containing navigation and electronic equipment.

The air conditioning system, boiler units and electrical heaters provided shall be capable of maintaining the indoor climate requirements outlined in Table 1 and have the ability to isolate/winterize during the off season.

For Ranger IV, the Air Conditioning system is required to operate during the summer months when temperatures near the ports and islands rise rapidly. The system's capacity will be accurately determined during the Detailed Design and Construction (DD&C) phase with assistance from a specialized vendor.

Two boiler units (main and auxiliary) shall be provided. The boiler units shall be fuel fired and heat water in hydronic loops through individual HVAC zones. Each boiler unit shall be capable of supplying the full heating load of the vessel's hydronic heating system.

The heating system shall be capable of maintaining the indoor climate requirements outlined in Table 1 and have the ability to isolate/winterize.

Electric heaters may be incorporated in cargo or machinery areas for supplemental heating. Use of any electric heaters to satisfy climate requirements shall be approved by the NPS or their representative.

Preliminary/Contract Design of Motor Vessel Ranger IV

HVAC System Report

The below HVAC system depicts the major components with salient characteristics, preliminary ducting size, major vent trunks, space requirements and locations.

These calculations were performed based on preliminary inputs from available vendor information. The AC system's capacity will be determined during the Detailed Design and

Construction (DD&C) phase, which falls within the vendor's scope of work. Consequently, the relevant calculations and drawings are not included in this report.

2.0 CALCULATE MINIMUM SUPPLY FAN CAPACITY

2.1 Minimum Supply Fan Capacity based on Air Changes

Minimum Required air changes for Bow Thruster Room 10 Air changes/hr (Appendix-2)

The quantity of air required for Bow Thruster Room, QA = BTRL*BTRB*BTRD*Air changes

= 417.07 cfm
