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, the hotel contacted Carrier Rental Systems to request a fast-track hire solution until the equipment could be replaced.
“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,” said Tim Walker, technical services manager, Royal Garden Hotel. “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 the hotel’s cooling capacity by fifty percent, and presented us with a problem that required immediate action.”
The hotel asked Carrier Rental Systems to evaluate whether a temporary solution could be provided to supply the necessary level of cooling and quickly replace the lost air conditioning capacity.
Carrier Rental Systems recommended the temporary installation of two high performance Carrier AquaSnap® air-cooled 30RB 522 chillers, with rotary scroll compressors. These provided up to 1.2MW of cooling capacity to the hotel, fully replacing lost capacity from the out-of-commission unit with some extra capacity to spare.
With micro-channel condensers and high-efficiency variable condenser fans, the AquaSnap 30RB chillers operated with full load Energy Efficiency Ratio (EER) values of up to 10.3.
“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,” said Marc White, director, Carrier Rental Systems. “We were pleased to be able to fast-track the installation to ensure full service was resumed quickly.”
The AquaSnap 30RB chillers are equipped with stand-alone controls, and can also be connected to a building’s existing building management systems (BMS), enabling them to operate alongside other systems as part of a fully integrated building.
Carrier Rental Systems delivered, installed and commissioned the AquaSnap 30RB chillers over a weekend, minimising downtime and inconvenience for the hotel. Due to space constraints onsite, the temporary units were installed in the hotel’s goods delivery area.
“Although space was fairly limited in the vicinity of the chillers, the location provided a good solution,” said Walker. “While it was close enough to connect into the hotel’s existing air conditioning system, it did not create a disturbance for guests thanks to the quiet operation of the temporary chillers.”
The hire package included all maintenance during the 10 month rental period, plus full emergency response and repair service in the event of a problem.
“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,” said Walker. “In the end, we decided to replace the previous unit with a new Carrier machine.” Carrier Rental Systems holds a comprehensive range of temperature control rental equipment at locations around the UK, enabling a rapid response to HVAC breakdowns. Rental periods can be as short as one day to however long the temporary cooling solution is required.
