Daikin said that his new EWWH-VZ has water-cooled inverter kuiter and heat pump cooling and heating capacity, ranging from 400 kW to 1,900 kW. The system uses R1234ze as the coolant.
The manufacturer of the Japanese heating system Daikin has launched a new heat pump system for applications in industrial buildings and district heating.
The EWWH-VZ-Water-cooled inverter cooling machine and heat pump system uses Daikin’s Several screw compressors with a variable volume ratio (VVR) own technology, which reportedly calibrates the internal volume ratio according to the operating conditions of the unit.
“This system includes a mechanical mechanism that modulates the volume of the discharge gate, so that the compressor can delay or anticipate the end of the compression cycle,” the company said in a statement. “This minimizes under- or over-compression, reducing operating costs and improving long-term reliability. These benefits are particularly valuable in the demand of industrial applications where long-term performance and sustainability are crucial.”
The heat pump has cooling and heating capacity ranging from 400 kW to 1,900 kW and, according to the manufacturer, can reach hot water at temperatures up to 90 ° C.
The system uses R-1234ZE, a hydrofluorolefin (HFO) coolant with a warming potential (GWP) of 1.4. It also contains one Seasonal energy -efficiency (seer) ranging from 8.61 to 9.03.
The smallest system of the series Meet 2123 mm x 1,178 mm x 3.722 mm and has a weight of 2,892 kg. The largest unit has a size of 2,498 mm x 1.753 mm x 4,750 mm and weighs 8,260 kg.
“One of the most important strengths of the EWWH-VZ unit lies in its exceptional installation flexibility, making it ideal for limited spaces,” said Daikin. “This is made possible by the innovative knock-down electrical panel, which can be installed at a maximum of five meters from the head unit. This function makes installation in even the smallest technical rooms possible for replacing gas boilers.”
