DESCRIPTION

GLOBAL COLD  is air conditioning systems heat pumpsin direct expansion provider and installer using FUJITSU GENERAL Ltd brand, using R410A refrigerantusing one outdoor units connected to multiple indoor units of all types.

VRF is a direct direct expansion system that uses one indoor unit for each room or space, and all the indoor units are connected to a single outdoor unit which uses a refrigeration system adapting its power  to meet the needs of each indoor units  in order to the needs  of the spaces where it is installed anytime of the day a specially designed electronic valve injects the exact amount of refrigerant needed by any unit .

• the option of VRF2 pipe, all indoor units are identically connected to the same group(Heating and cooling)

• reversible VRF provides heating as well as cooling.

The VRF series V is a system that can work win one group (outdoor unit) with up to 48 indoor unts of different types (floor standing, cassette as well as wall mounted indoor units).

Except for the 8HP group, all our models are compatible either by using the COP or oe a map of compact groups. The total the length of pipes can be increased of 300m to 500m, with a hight difference of 50m between the indoor and outdoor units, the energy efficiency is globally improved. Te EER at full lead COP of 2.3 in coolo,gmode 3.8 in heating mode.

VRF SERIES V is equipped with a computing device and an automatic charge commissioning and technical monitoring of the facility.

Features

V series VRF systems are easily adaptable to the changes in room and indoor units can be added to the system up to a power level of 150% of a single unit and up to 150% of a bi-split and up to 130% of a tri-split.

With V series VRF system, the length of piping system  calculation is no longer necessary thanks to the innovative technology the compressor especially designed for the multi indoor unit system.

• low noise level in night mode max 8db

• anti corrosion treatment of the heat exchangers makes it 5 to 6 times more resistant to corrosion.

• The use of double back up function in case of compressor failure be it either remote control or on-site controller in the indoor unit and the outdoor unit

Automatically starts emergency compartment of a secondary compressor to maintain a provisional maximum power for 8 hours.

• minimum quantity of refrigerant gas in the system

• presence of a device equalizing the pressure within the compressor to help restart.

• Refrigerant oil recovery cycle (after 8 hours running) the inverter compressor is powered at higher frequency than that of a standard compressor , the 4way valve set off for cooling mode and electronic expansion valve at high run mode.

Auto diagnosis

• detects the malfunction of the main parts of the system and displays the type of malfunction which improves maintenance and troubleshooting.

• anti short-circuit a minimum downfall of 5min is provided.
