EUROPE: Daikin is expanding its heat pump range with the launch of the new EWYK-QZ R290 (propane) modular air-to-water heat pump at this month’s ISH in Frankfurt.
Providing cooling and heating capacity from 100 kW in a single module to 2000 kW in a multi-module system, the EWYK-QZ is designed for a wide range of applications including heating, cooling and hot water supply.
The system is officially scheduled to launch later this year, but visitors to ISH Frankfurt will be able to see the prototype for the first time from March 17 to 21.
The system can replace conventional boilers and provide hot water up to 75°C. In cooling mode, it is claimed to operate effectively at temperatures from -15°C to 27°C at the evaporator outlet and can operate at ambient temperatures from -20°C to 46°C.
The modular concept allows multiple units to be connected and controlled as a single unified system, making it an easy to implement plug and play solution when used with a Daikin manifold kit and pump module.
Additional modules can be easily integrated into building extensions to increase heating or cooling capacity. Each module comes in 100 kW or 125 kW versions, and up to four modules can form a 500 kW array. Four arrays (16 modules) can be combined to create a 2,000 kW system controlled by Daikin’s Intelligent Chiller Manager (iCM) control system.
Using propane refrigerant, Daikin has incorporated a number of safety features to ensure safe and reliable operation, including two refrigerant leak detectors – one on the refrigerant circuit and one inside the junction box. Also included is an exhaust fan to quickly dissipate refrigerant in the event of a leak and a junction box fan for added safety. In addition, visual and audible alarms are also built in.
To ensure performance, the EWYK-QZ uses inverter-controlled scroll compressors and brushless fans.
