1. Hydraulic Kit (pump and tank) Pictures from prototype

2. Hydraulic Kit (pump and tank) Main Characteristics Size and shape = 5 HP unit 100 litre tank for all models Separate power supply Anti Freeze protection

3. Qx1000 x  t V =  xdxCw x n 100 litre tank for all models ? The water (glycol) volume should be so big that the time necessary to pull down the water temperature equal to the thermostat difference, is half the time of the anti-recycling time Q = Cooling Capacity at the lowest capacity step (W) t = Anti-recycling time of the compressor (s)  = Specific mass of the fluid (kg/m³) d = Thermostat difference (step length) (°C) Cw = Specific heat of the fluid (J/kg°C) (4186 for water) n = Nr of compressors that can work independently

4. 7 6 Thermostat Difference 5 100 litre tank for all models ? Water Out (°C) More Water Less Water Time sec.) The water (glycol) volume should be so big that the time necessary to pull down the water temperature equal to the thermostat difference, is half the time of the anti-recycling time

5. 7 6 Thermostat Difference 5 Anti Recycling Timer 100 litre tank for all models ? Water Out (°C) Water Volume should be selected to cope with the anti-recycling timer of the compressor Compressor On Compressor On Time sec.) 240 The water (glycol) volume should be so big that the time necessary to pull down the water temperature equal to the thermostat difference, is half the time of the anti-recycling time

6. Only 1 compressor: Example: EUWA20HZ Nominal Cooling Capacity: 42 kW Load: 21 kW Capacity Step: 0 - 100% Thermostat Difference: 1,5 °C Anti Recycling Timer: 240’’  Only half the capacity of the chiller is required… The water (glycol) volume should be so big that the time necessary to pull down the water temperature equal to the thermostat difference, is half the time of the anti-recycling time

7. For 1 compressor: During On - mode: System will cool down with a capacity of 21 kW During Off - mode: System will heat up with a capacity of - 21 kW The water (glycol) volume should be so big that the time necessary to pull down the water temperature equal to the thermostat difference, is half the time of the anti-recycling time

8. Thermostat Difference Anti Recycling Timer For 1 compressor: Water Out (°C) Cooling 21 kW Heat Up: 21 kW Time sec.) Compressor Off 240 The water (glycol) volume should be so big that the time necessary to pull down the water temperature equal to the thermostat difference, is half the time of the anti-recycling time

9. m =  * V cwater = 4186 J/kg°C V = 21000 W * 120 s 4186 J/kg°C* 1,5 °C For 1 compressor: Out of the formula Q = m * c * T Q = m / (t) * c * T m = (Q *  t) / (c * T) V = 400 l The water (glycol) volume should be so big that the time necessary to pull down the water temperature equal to the thermostat difference, is half the time of the anti-recycling time

10. For 2 compressors: Example: EUWA20HZ Nominal Cooling Capacity: 42 kW Load: 21 kW Capacity Steps: 0 - 50 - 100% Thermostat Difference: 1,5 °C Anti Recycling Timer: 240’’ The water (glycol) volume should be so big that the time necessary to pull down the water temperature equal to the thermostat difference, is half the time of the anti-recycling time

11. For 2 compressors: Compressor 1 can operate continuously Compressor 2 is continuously switched off Capacity = Load Constant Temperature is obtained  no buffer tank needed The water (glycol) volume should be so big that the time necessary to pull down the water temperature equal to the thermostat difference, is half the time of the anti-recycling time

12. Thermostat Difference Anti Recycling Timer For 2 compressors: Water Out (°C) Time sec.) Compressor Off 240 The water (glycol) volume should be so big that the time necessary to pull down the water temperature equal to the thermostat difference, is half the time of the anti-recycling time

13. For 2 compressors: Example: EUWA20HZ Nominal Cooling Capacity: 42 kW Load: 10,5 kW Capacity Steps: 0 - 50 - 100% Thermostat Difference: 1,5 °C Anti Recycling Timer: 240’’ The water (glycol) volume should be so big that the time necessary to pull down the water temperature equal to the thermostat difference, is half the time of the anti-recycling time

14. On Off 21 kW 10,5 kW Cooling Down 1 2 2 2 0 kW - 10,5 kW Heating Up 1 1 1 21 kW 10,5 kW Cooling Down 2 0 kW - 10,5 kW Heating Up For 2 compressors: Auto lead - lag switching CAPACITY LOAD The water (glycol) volume should be so big that the time necessary to pull down the water temperature equal to the thermostat difference, is half the time of the anti-recycling time

15. Compressor 1 On Compressor 2 On Thermostat Difference Anti Recycling Timer For 2 compressors: Water Out (°C) Cooling 10,5 kW Heat Up: 10,5 kW Compressor Off Time sec.) 240 The water (glycol) volume should be so big that the time necessary to pull down the water temperature equal to the thermostat difference, is half the time of the anti-recycling time

16. For 2 compressors: V = 10500 W * 60 s 4186 J/kg°C* 1,5 °C V = 100 l The water (glycol) volume should be so big that the time necessary to pull down the water temperature equal to the thermostat difference, is half the time of the anti-recycling time

17. 10 + 10 + 10 The max. water volume is determined by the capacity of a 10 Hp compressor
