CRS delivers fast-track air conditioning hire solution for Kensington's Royal Garden Hotel
Carrier Rental Systems (UK) Limited has provided a temporary air conditioning solution for one of London’s top hotels.
When a chiller serving Kensington’s prestigious Royal Garden Hotel failed during a busy period, they contacted CRS to see if we could provide a fast-track hire solution until the system could be replaced.
Tim Walker, Technical Services Manager at the hotel, explained: “We pride ourselves on providing guests with the highest levels of comfort, and air conditioning is obviously an essential element of the five-star experience.
“It was a particularly busy period, with full occupancy during a major international sporting event. A breakdown of one of our long-serving chillers reduced cooling capacity by 50 per cent, and presented us with a problem that required immediate action.”
The hotel asked CRS to evaluate whether a temporary solution could be provided to supply the necessary level of cooling and quickly replace the lost air conditioning capacity.
CRS recommended temporary installation of two high performance Carrier Aquasnap air-cooled 30RB 522 chillers, based on R410A and the latest rotary scroll compressors. These provided up to 1.2MW of cooling to the hotel, fully replacing lost capacity from the out-of-commission machine, with some extra ‘headroom’ capacity to spare.
With micro-channel condensers and high efficiency fans, the chillers operate with full load EER values of up to 10.3.
Marc White, CRS director, said: “The scroll compressor-based machines have multiple refrigerant circuits, giving excellent resilience and a high level of assurance for end users in critical applications such as hotels. Due to the use of Bauer hoses, fittings and couplers we were able to fast-track the installation, to ensure full service was resumed extremely quickly.”
The chillers are equipped with stand-alone controls, and can also be connected to a building’s existing BMS, enabling them to be operated alongside other systems as a fully integrated plant.
CRS delivered, installed and commissioned the chillers over a weekend, minimising downtime and inconvenience for the hotel. Due to space constraints on site, the units were sited in the hotel’s goods delivery area.
The hire package included all maintenance during the 10 month rental period, plus full emergency response and repair in the event of a problem.
Tim Walker said: “Although space was fairly limited in the vicinity of the chillers, it provided a good solution as it was close enough to connect into the hotel’s existing air conditioning system and, at the same time, with the excellent noise performance of the temporary chillers, not create disturbance for guests.”
He added: “The hire option provided a swift and effective solution that solved the immediate need, and gave us time to properly assess the requirements for repair or replacement of existing plant. In the end, we decided to replace the previous unit with a new Carrier machine.”
