Royal Thai Embassy

The new site for the Royal Thai Embassy saw Fletcher Construction completely gut the existing two storey tavern (which had become a blot on the local landscape after 15 years of abandonment) and add a third level extension providing function space and accommodation.

The Challenge

This building is mainly office space, but the extension houses large function and pre function spaces, a commercial kitchen on the ground floor and four two bedroom apartments above. All of which require heating, cooling and adequate ventilation.

The challenge was to design an air conditioning system that suited the many different spaces and purposes. The building required a number of different products to ensure that all spaces were provided with the heating or cooling they needed. Added to this, the outdoor condenser plant decks were very tight – so finding a logical site would require its own solution.

Added to the practical nature of the project was the challenge of ensuring that our customer, Aquaheat, was made to feel like we were on top of the project the entire time as we were the main supplier for most of the building’s mechanical services.

The Solution

230kW of City Multi R2 Series simultaneous heating and cooling condensers were installed to serve the office areas. These office areas are exposed to all four orientations creating a huge potential for heat recovery. The indoors are primarily low profile (250mm) mid static ducted units, offering up to 150Pa of external static pressure. Three four way blow cassettes have been installed in a detailed ceiling within the reception area.

A further 134kW of S and Y Series condensers have been used for the remainder of the building. The Y series condensers have been utilised to build large 28kW ducted split systems, one in each of the 3 conferences spaces. A portion of tempered fresh air is brought onto the rear of these indoors to meet the building code. The S Series condensers have been utilized to build a three-headed multi to service the living room, and 2 bedrooms in each of the four apartments. To address the tightness of the plant decks it was decided that two separate spaces on the site were required.
