FX-G05 - Low GWP refrigerant

All-round approach to sustainability

Delivering brilliant annual efficiency is

fundamental, but is not enough.

New regulations like the EU F-gas and the

Kigali Amendment to the Montreal Protocol are

driving the industry towards new low GWP

refrigerants.

Today, an extended approach is the only way to effectively

reduce the Total Equivalent Warming Impact (TEWI).All-round sustainability

39


Possible alternatives

Sniffer function: When there is no request for cooling production, the primary pumps (built-in or external) are switched off and activated periodically only to let the unit

read the water temperature and sense the cooling request inception. Compatible with both constant and variable flow control.

46


Variable primary flow

The VPF control series (Variable Primary Flow) doesn’t only adjust the pump speeds on the basis of the

plant’s thermal load, but also dynamically optimizes the unit’s thermoregulation for variable flow

operation, thus ensuring both the highest pump energy savings and chiller stable operation.

Systems with only the primary circuit. Systems with primary and secondary circuits separated by a hydraulic decoupler.

VPF.D: constant ∆TVPF: constant ∆P

With the VPF system, the water flow can be reduced to 50% of the unit nominal water flow, with regards to the selection conditions, provided that the minimum water flow required by the unit’s heat exchanger is respected.

47


Pump group composition

The factory-mounted components of the pump groups are:

• Single-stage, close-coupled pumps by Grundfos.

• SiC/SiC (silicon carbide) primary seal pairing, extremely

resistant against wear, abrasive particles and wear.

• EPDM bellows seal prevent the risk of deposits, such as

rust, on the shaft.

• Pull-out design: during maintenance the power head can

be pulled out without removing the pump housing from the

pipework.

In-line pumps End-suction pumps

• Pumps*1 or 2 pumps, 2 or 4 poles, low or high head,

Fan speed controls

Variable speed DVVF (std):

Device for controlling the condensation by adjusting the fan speed with

voltage steps (auto-transformer), fitted with a ventilation distribution

system in case of external air low temperature.

EC fans (Opt. 808):

Electronically commutated fans with brushless motor to continuously

adjust the speed in order to minimize energy consumption and noise

emissions, especially at part loads (+1% of EER, +5% of SEER).

Input and connection

4-20 mA (Opt. 6161):

Enables remote set-point adjustments (analog input).

Double set-point (Opt. 6162):

Enables the remote switch between 2 set-points (digital input).

Demand limit (Opt. 6171):

Limits the unit's power absorption for safety reasons or in temporary

situations (digital input).

Auxiliary

input

Connectivity

BMS connection: Serial card interface module to allow integration with BMS protocols:

Modbus (Opt. 4181) LonWorks (Opt. 4182)

BACnet MS/TP (Opt. 4184) BACnet over IP (Opt. 4185)

M-Net interface kit (Opt. 4187):

Interface module to allow the integration of the unit with Mitsubishi

Electric proprietary communication protocol M-Net.

65


Electrical accessories

Energy meter for BMS (Opt. 5924):

Acquires the electrical data and the power absorbed by the unit and

sends them to the BMS for energy metering (Modbus RS485).Energy meter

Compressor rephasing (Opt. 3301):

The capacitors on the compressors’ line increase the unit’s power factor.

Automatic circuit breakers for compressors (Opt. 3411)

or all major electrical loads (Opt. 3412):

Protect the compressors or the compressors and fans from possible

current peaks, over-current switches are provided in place of the

standard fuses.

Soft-starter (Opt. 1511) or 3-phase soft-starter (Opt. 1513):

Manages the inrush current enabling lower motor windings’ mechanical

wear and avoidance of mains voltage fluctuations during starting.

Electrical

66


Refrigerant circuit accessories

Dual pressure relief valves with switch (Opt. 1961):

One valve is isolated from the refrigerant circuit while the other is in

service. The user can work on the isolated valve for periodic maintenance

or replacement, without removing the refrigerant from the circuit.

Compressor suction valve (Opt. 1901):

Installed on each compressor suction line, simplify maintenance activity

(discharge valves are present as per standard).

Refrigerant

circuit

Leak detector (Opt. 3431):

Factory installed device, placed within the compressor enclosure. In case

of a gas leak detection it raises an alarm.

Leak detector + compressor off (Opt. 3433):

Factory installed device, placed within the compressor enclosure. In case

of a gas leak detection it raises an alarm and stops the units.

Leak

67


Hydraulic and mechanical accessories

Water flow switch (Opt. 1801):

Designed to protect the unit where the water flow across the evaporator

is not sufficient and falls outside of the operating parameters.

Delta T > 8°C (Opt. 2881):

Evaporator designed to operate with low primary circuit water flow.

Flanged hydraulic connections (Opt. 2911):

Grooved coupling with flanged counter-pipe.

Hydraulic

Anti-intrusion grilles (Opt. 2021):

Perimeter metal grilles to protect against the intrusion of solid bodies into

the unit structure.

Rubber type (Opt. 2101) or spring type (Opt.2102)

anti-vibration mountings:

Reduce vibrations, keeping noise transmission to a minimum.

Mechanical

Packing

Standard

Container packing (Opt. 9979)

Nylon packing (Opt. 9966)

Reinforcing bars (Opt. 1971): steel brackets used to strengthen the unit structure. Suggested in case of long truck transport.

FX-G05 is provided with nothing but the lifting eye-plates,

to load the unit into a truck.

FX-G05 is covered with a protective nylon layer and provided with the lifting eye-plates,

to load the unit into a truck.

FX-G05 is covered with a protective nylon layer, provided with structural reinforcing bars and equipped

with both lifting eye-plates and handling devices to load it on a container (metal slides, front handling bar).

From the facility, the unit can be loaded directly into a container, or into a truck for a future container load.
