Fateh Prakash Palace Hotel stands majestically along the
shore of Lake Pichola in Udaipur.

Modern Technology for

Air Conditioning a
Heritage Palace-turned-Hotel
By Pankaj R. Dharkar, Member ASHRAE,
ISHRAE
At the time of independence from British
rule in 1947, India had more than 500 princely states, referred to as “native” states by the
rulers, which had not been conquered or
annexed by the British and were not part
of British India. All of these princely states
were merged into the Indian Union and
the palaces of the rulers, or “Maharajahs,”
were slowly converted into luxury hotels for
tourists, anxious to savor the opulence and
living style of the Maharajahs.
One such heritage palace that was
turned into a hotel is the Fateh Prakash
Palace, named after Maharana Fateh
Singh of Mewar, who ruled from 1885
to 1935. Standing majestically along the
shore of Lake Pichola in Udaipur, in the
present-day state of Rajashtan, the palace
is about 100 years old and has one of the
country’s largest Durbar Hall (or banquet
hall). It is a column-less structure with
huge steel girders that were shipped all
the way from England.
The present day hotel, with distinctive
turrets and majestic domes, is a treasure
trove of exquisite chandeliers, priceless
paintings, unique crystal and crockery
collections and has been certified as the
best heritage hotel in the “Heritage Grand”
category by the Department of Tourism,
Government of India.

Synopsis of System Design
The owner desired the renovation of
the palace to be carried out so that some
of the existing areas could be refurbished
and used commercially. Development was
to be carried out in two phases because
the hotel was to be kept operational for
guests throughout the retrofit work.
In Phase 1, it was proposed to replace
the existing 75 ton (265 kW) DX plant for
the Durbar Hall and a 15 ton (53 kW) DX
plant for the Galleria restaurant (which
runs parallel to the hall and overlooks the
lake) with a VRF system.
Retrofitting the old DX plant with
compact VRF technology was the only
option that could have given the flexibility
required and, at the same time, save considerable space from the area vacated by
the old DX plants. The space was enough
to create six new additional guest rooms,
as well as a new banquet hall of 5,000 ft2
(465 m2) with its kitchen at a lower level,
which was originally used as a store and
utility area.
After the successful completion of
Phase 1, including the creation of six new
guest rooms and banquet hall, the management decided to increase the capacity
after seeing the growing popularity of
the hotel.
Phase 2, comprises an additional 32
luxurious guest rooms, presently under
construction.

Air-Conditioning System
Durbar Hall and Galleria Restaurant (or
existing areas)
• Durbar Hall was continuously reserved for some function or the
other, and so the installation work
had to be carried out with minimum shutdown periods and at
odd hours.
• A total of 75 ton (265 kW) for the
Durbar Hall and 15 ton (53 kW)
for the Galleria was the new VRF
capacity. With the constraints of
a heritage building, the five new
15 ton (53 kW) air-handling units
were located in Durbar Hall in the
same niches where the old DX
units were placed to maintain the
integrity of the heritage structure
and to avoid altering or breaking
any of the walls. The units, weighing 0.66 tons (600 kg), had to be
