1 IT COOLING

2 Range of precision air conditioning units for IN-ROW installation available in the following versions: i. Direct Expansion air cooled: 2 models with nominal cooling capacity 25 & 40 kw. Water cooled version under evaluation ii. Chilled water: 2 models with nominal cooling capacity 50 & 60 kw. The COOL ROW range alongside the actual COOLSIDE EVO increasing the RC Group offer for precision air conditioning units for application in a fast growing market. 2

3 COOL ROW: fan section cold isle side with closed door 3

4 The ENERGY SAVING oriented general / operating characteristics as well as the fitted components allow to fully meet various and sophisticated needs of today Data Halls with hot spots / high concentrated loads: i. Application in installations with hot / cold isle lay-out, with or without containment ii. iii. iv. Installations requiring load sharing working logic, with ALL units in operation at partial load for maximum energy saving Cold isle temperature control through cooling capacity modulation based on supply air temperature Hot isle temperature or differential pressure control through air flow modulation 4

5 COOL ROW DX: main characteristics: i) Single cabinet for both models: 600 x 1200 x 2000(h) mm. ii) iii) iv) Back air return from hot aisle and frontal or side air supply into cold isle Built-in single scroll BLDC inverter compressors (EC compressor) specific for R410A Nr. 4 x Plug Fan Radical type with brushless EC electric motors in compliance with the ERP 2015 norm v) Finned package high efficiency evaporator with copper tubes and aluminum fins vi) Electronic expansion valve BLDC SCROLL COMPRESSOR ELECTRONIC EXPANSION VALVE VENTILATORE PLUG FAN Con motore elettrico di tipo EC 5

6 COOL ROW: fan section cold isle side with open door 6

7 COOL ROW DX: control system: Same advanced microprocessor fitted in NEXT EVO INVERTER for simultaneous control of cold isle temperature and either temperature or differential pressure of hot isle. Two control logic based on cooling capacity and air flow control: LOGIC 1: i. Cold isle temperature control through cooling capacity modulation. The BLDC inverter compressor changes the speed following the supply air temperature (supply air temperature control) ii. Hot isle temperature control through fan speed modulation. The Plug Fan EC type fans change the speed following the return air temperature (return air temperature control) 7

8 COOL ROW DX: control system: LOGIC 2: i. Cold isle temperature control through cooling capacity modulation. The BLDC inverter compressor changes the speed following the supply air temperature (supply air temperature control) ii. Hot isle differential pressure control through fan speed modulation. The Plug Fan EC type fans change the speed following the differential pressure between hot and cold isle (differential pressure control) 8

9 COOL ROW : i. CHW coil ii. electric panel iii. differential pressure sensor hot isle side with open door 9

10 COOL ROW DX: main accessories: i) Additional water coil ( extra-circuit) ii) iii) iv) 3 stage electric heater: 3 x 850 W Adiabatic ultrasonic humidifier: 1.0 kg/h Isotherm electrode humidifier: 2.0 kg/h v) G4 efficiency return air filter vi) Microprocessor accessories: same as NEXT EVO INVERTER 10

11 COOL ROW CW: main characteristics: i) Single cabinet for both models : 600 x 1200 x 2000(h) mm. ii) iii) iv) Back air return from hot aisle and frontal or side air supply into cold isle Nr. 4 x Plug Fan Radical type with brushless EC electric motors in compliance with the ERP 2015 norm Finned package high efficiency CHW coil with copper tubes and aluminum fins v) 2-way CHW valve 11

12 COOL ROW CW: control system: Same advanced microprocessor fitted in NEXT EVO CW for simultaneous control of cold isle temperature and either temperature or differential pressure of hot isle. Two control logic based on cooling capacity and air flow control : LOGIC 1: i. Cold isle temperature control through cooling capacity modulation. The CHW valve opens or closes following the supply air temperature (supply air temperature control) ii. Hot isle temperature control through fan speed modulation. The Plug Fan EC type fans change the speed following the return air temperature (return air temperature control) 12

13 COOL ROW CW: control system: LOGIC 2: i. Cold isle temperature control through cooling capacity modulation. The CHW valve opens or closes following the supply air temperature (supply air temperature control) ii. Hot isle differential pressure control through fan speed modulation. The Plug Fan EC type fans change the speed following the differential pressure between hot and cold isle (differential pressure control) 13

14 COOL ROW CW: main accessories: i. PICCV type CHW valve, independent from the pressure ii. iii. iv. Additional water coil (extra-circuit) 3 stage electric heater: 3 x 850 W Adiabatic ultrasonic humidifier: 1.0 kg/h v. Isotherm electrode humidifier: 2.0 kg/h vi. vii. G4 efficiency return air filter Microprocessor accessories: same as NEXT EVO CW 14

15 COOL ROW CW: the PICCV chilled water valve: Chilled water valve type PICCV (Pressure Independent Cooling Control Valve) One common body housing: - control valve - balancing valve - stop valve Advantages: - constant water flow when pressure changes - energy consumption optimization - simplified design - No balancing necessary for the plant 15

16 COOL ROW: i. CHW coil ii. PICCV valve iii. IN/OUT CHW pipes hot isle side with open door 16

17 COOL ROW: selling points i. Scroll inverter compressors BLDC (Brushless Direct Current) type (EC compressors) with very high energy efficiencies; higher than the ones of scroll inverter compressors no BLDC ii. iii. iv. Plug Fan EC radical type fans in accordance with the ERP 2015 Norm Large accessories availability, including PICCV type CHW valve Internal components lay-out, design of refrigerant /water pipes to minimize pressure drops on both air & refrigerant/watersides 17
