Daikin water cooled chiller.
Available in a wide range of cooling capacities and component combinations, the new B Vintage chillers have been designed to deliver optimal performance at both full and part-loads. They can also operate with a choice of refrigerant* including low global warming potential (GWP) R513A and R-134a in single or dual compressor models.
This is in line with the company’s philosophy of offering increased refrigerant choice to ensure customers comply with regulatory requirements, but without any need to sacrifice system performance.
DAPUK manufactures several types of centrifugal chiller to meet a wide variety of applications, including commercial cooling, district energy systems and manufacturing processes. Its centrifugal compressor has also been designed for simplicity with minimal components to improve durability and reliability.
The single compressor version of the B Vintage range (DWSC) provides excellent full and part-load performance. The dual compressor version (DWDC) provides outstanding part-load efficiency as well as system redundancy equivalent to two chillers, but at 35% lower cost than installing two separate chillers thanks to reduced hardware, installation and components.
B Vintage chillers can be accurately sized to meet the specific needs of a project thanks to the availability of DAPUK’s ‘right-sizing’ selection programme. The inverter also features flexible control functions that closely match the chiller’s performance to operating conditions. This means the system can deliver the required cooling capacity, but at minimal running speed so significantly reducing energy consumption.
Daikin’s inverter uses fewer and lighter internal components than other models available on the UK market. This creates the right balance between cost and performance while also reducing vibration and ensuring the chiller operates in the appropriate gear ratios to provide optimum impeller speed whatever the application. This compares favourably with older direct-drive designs, which could suffer from high levels of vibration and stress on the shaft and motor.
* R-134a is a chlorine-free refrigerant with zero ozone depletion potential and R513A has lower GWP. Both will remain available in the long-term under the terms of F-Gas regulation phase down process to support the operating life of the new DAPUK chillers.
