“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.”
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 operate with full load Energy Efficiency Ratio (EER) values of up to 10.3.
Marc White, director, Carrier Rental Systems, 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. 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.
