CLOSE CONTROL SYSTEM

Energy Saving Technology

Low Running Cost

The inverter driven compressors can maximize the energy efficiency of PFD series, leading to reduction of power consumption. PFD series coefficient of performance (COP) are over 3.00 in cooling mode. [Sensible heat factor (SHF) : 0.93]

Low Power Consumption

Plus, new PFD series adopt advanced R410A refrigeration and control technology to offer lower power consumption.

Minimum Humidifiers

PFD series work without a humidifier in most specifications. Due to the use of an optimized inverter driven compressor, PFD series minimize the excessive dehumidification whereas other systems need a separate humidifier for each indoor unit.

CLOSE CONTROL SYSTEM

MITSUBISHI ELECTRIC’s Close Control System (PFD series) is specifically designed for computer rooms, laboratories etc, where strict control of humidity and temperature is a must. It possesses “High Reliability”, “Energy Saving Technology”, and “Easy Installation / Maintenance”. It can be connected to a computer network using our AG-150A controller, in order to monitor from a distance and provide remote email alarms.

High Reliability

Precise Room Temperature Control

(Cooling)

PFD series maintain a nearly constant room temperature (within ±1.0

˚C) without the typical temperature changes that occur with conventional ON/OFF control systems with inverter driven compressor.

Suction air temp

Time

Quick Recovery from Power Failure

After an initial setting of outdoor unit is completed within 20 seconds of power recovery, thermo ON

signal will turn on and it will take 5 seconds for an outdoor unit fan and compressor operation to start.

PFD unit will restart within 20 seconds+(indoor unit address/2). To prevent the inrush current when

recovering from power failure, the indoor unit system will restart one by one.

Protection of Confidential Information

As a compressor has been incorporated into the outdoor unit, the compressor can be serviced without entering a computer room. Our close control system can protect confidential information.

available with both air and water cooled outdoor unit.

PFD + Air cooled outdoor unit

When connecting PFD-P500VM-E and P500 outdoor unit, either 1 or 2 refrigerant circuit connection is available depending on system size and usage. With 2 refrigerant circuit connection, one circuit can back up the other. If installation and large number of units are to be installed, single refrigerant circuit can be selected.

Because the system is water

cooled, the outdoor air temperature

does not affect capacity. Futhermore, water cooling means no defrost operation is required, so rapid starting assures quick and continuous cooling in the hottest conditions.

City Multi WR2 series, Heat recovery

between Heat Source Units is possible.
