Euroklimat high temperature heat pumps for an important hotel in Dubai
During the year 2020, Euroklimat designed, built and tested 6 high temperature heat pumps HPV-W-HHT 592-C-1 units for one of the most important and evocative hotels in Dubai in the United Arab Emirates. This solution made it possible to replace an obsolete Domestic Hot Water production system based on electric resistances with a much more effective and efficient system that uses a vapor compression refrigeration cycle. The major consequence is that at the same level of comfort, 3.9 million kWh are saved every year (equivalent to the consumption of more than 270 homes) and consequently the emission of 1.5 million kg of CO2 into the atmosphere is also avoided.
Going into more detail, all the units contain the R134a refrigerant fluid and are classified as Water-to-Water type, therefore suitable for indoor applications. Each unit is equipped with a two-stage screw compressor which allows to obtain high efficiency and reliability, together with wide operative limits. Furthermore, the use of an inverter whose task is to vary the operating frequency of the compressor, allows to follow the thermal load with extreme precision, reducing any type of inefficiency especially in partial load conditions. Each unit is also equipped with a direct expansion Shell & Tube evaporator, a double pass Shell & Tube condenser, a brazed plate economizer and an electronic expansion valve.
The units have been divided on two sides of the imposing structure, 3 used on the East side and 3 used on the West side. Furthermore, each group of units is managed with Master-Slave logic, which can be implemented through the latest generation of advanced controllers. This unit management mode allows to achieve high levels of efficiency, as a unit is activated only if necessary and if energy-efficient.
Each unit at full load capacity can produce 613 kW with hot water at 70 °C and with the source at 10 °C. In this condition, the COP (Coefficient of Performances) is equal to 3.23.
