VRV-IV-Q

 

Reusing existing piping for speedy replacement to an advanced energy-saving air conditioning

Upgrading air conditioning systems in the past used to require replacement of refrigerant piping in buildings, leading to major construction and costs exceeding those of the original installation.

To save time and cost, Daikin developed the VRV IV Q Series as a model specializing in system replacement, This revolutionary system reuses existing piping and enables quick and high quality replacement to the latest energy-saving air conditioning system without renovation work for new piping.

 

Reusing existing refrigerant piping minimizes:

  • Piping removal and new construction along with installation time and cost
  • Impact to the interior and exterior of buildings
  • Suspension of daily business operations for renovation

 

Improvement in capacity and greater number of indoor units with VRV IV Q Series:

  • Increase in capacity is possible while using existing piping
  • Moor indoor units can be connected in a single system, enabling consolidation of existing piping.

 

An automatic refrigerant charge function enables high quality installation for the VRV IV Q Series:

  • The system is automatically charged with the proper amount of refrigerant even when the length of the existing piping is unknown
  • Equipment automatically performs a sequence of tasks from refrigerant charging to test operation

VRV-IV-AHU System

AHU1

 

VRV AHU Introduction

Daikin released  2 series of VRV AHU,standard series model AHUR-DBV/CBV and outdoor air series model AHUR-DBL/CBL. It is a DX AHU that is specially designed to operate with VRV IV outdoor unit. This enabled the users to  reduce maintenance costs and enjoy more space savings.

Daikin VRV AHU improves the indoor air quality caused by haze, pollutants, etc with options of pre-fillers and primary filters.

This is the only total AHU solutions provided and manufactured completely by Daikin.

AHU2

What is VRV?

Daikin VRV system is a multi-split tye air conditioner for commercial buildings that uses variable refrigerant flow control invented by Daikin.

AHU3

It allows one touch selection control using intelligent Touch Manager and includes options to link with BACnet to enhance the Building Management System (BMS).

 

VRV AHU Application

From small to large commercial spaces, Daikin offers a wide range of R-410A inverter condensing units for use in conjunction with Air Handling Units(AHU) from 6 HP to 120 HP.

AHU provides large air volumes and high ESP (External Static Pressure) enabling the use of extensive ductworks. The refrigerant flows through the copper pipes using R-410A and operates like a large VRV fan coil unit.

Daikin AHU represents the ideal solution for large storage places, atrium, lobby, banquet halls, showrooms, exhibition halls, shopping malls, etc.

It also has the options to customize the specifications such as the filtration type, direction of air in-take and discharge, servie access door and blower type(backward or forward curves and plug fan).

VRV User Benefits

 

For property OWNERS

First launched in 1982, the Daikin VRV system has been providing comfort and reliability to building owners and their tenants for over 35 years. Leveraging the latest in energy-              saving technology, Daikin has further improved energy savings while reducing space requirements. This added value is one reason why Daikin is the right choice for building                  owners.

 

Energy saving & comfortable environment

  • Based on the idea of using only as much space as absolutely required, Daikin first launched its commercial multi-split air conditioning systems in 1982. Since then, customers have benefitted from much increased energy efficiency. Now, our revolutionary new systems dramatically reduce energy with VRT Smart Control. During operating periods, control programs ensure thermal loading is generally low, thus boosting energy efficiency. This greatly reduces the amount of energy required for building air conditioning. While optimally operating at low load, it maintains a comfortable indoor environment.

 

X11x12

 

Efficient space utilisation

Daikin VRV system can be used to develop a large-scale air conditioning system on a single refrigerant system, thus reducing the space required for air conditioning equipment. Because the difference in height between the indoor and the outdoor unit can be as large as 90 m, even with a 20-storey building all of the outdoor units can be placed on the rooftop for more efficient utilisation of space.

X13

 

High reliability

Double backup operation

  • Daikin VRV outdoor unit goes beyond just highly reliable compressors with a backup system that ensures continued operation.

Unit backup

  • Should one outdoor unit in a multiple unit system fail, the other outdoor units switch to emergency operation. If for some reason a failure occurs, the system for that unit does not completely stop, and air conditioning is maintained.

Compressor backup

  • Since units are equipped with two compressors, even if one compressor fails, the other compressor carries on in emergency mode

X14

 

For USERS

Comfortable environment

  • While operating optimally at low load, VRT smart operation maintains the indoor temperature and ensures a comfortable environment.

x15

 

Residential indoor units

  • Because indoor units developed for residential use can be connected, it is possible to realise quiet operation. You can include indoor units that operate at min.19 dB(A), and to reduce the noise of refrigerant passing through the piping by remotely installing an BP unit.

*For indoor units connectability, please refer to the indoor unit product lineups.

X16

 

For CONSULTANT and DESIGN OFFICES

Varied lineup of models

  • System applications range from family residences to large commercial buildings. With various types of indoor units available, comfortable airow is ensured in every space

 

Long piping provides more flexible system design

  • Greater design freedom is provided because equivalent piping between indoor and outdoor unit can run as large as 190 m and reach a maximum height difference of 90 m.

X17

 

Compatible with engineering software

  • We at Daikin provide the software, the simulation results, and drawing materials to support the business-information modeling (BIM) currently entering the mainstream in construction industries.

 

Energy efficient

  • Daikin’s innovative energy-saving technology helps you to achieve your green building solution.

X18x19

 

For Installers

Automatic refrigerant charge function

  • The automatic refrigerant charge function automates the charging of the proper refrigerant amount and the closing of shut-off valves by simply pressing a switch after pre-charging. Simplified installation eliminates excessive and insufficient refrigerant charge amounts due to calculation mistakes, and this has led to higher installation quality

Lightweight and compact large-capacity single units

  • Systems can be configured with single modules providing up to 20 HP. The lightweight and compact bodies are both easy to install and can be transported in elevators.

Simple piping, easy wiring

  • The REFNET piping system and DIII-NET system simplify refrigerant piping and control wiring installation.

Efficiency During Actual Operation

X23

 

Optimum utilisation of VRT Smart Control and VRT Control

Effectiveness can be demonstrated for VRT Smart Control and VRT Control when all the indoor units operate under low load conditions in a similar manner. Low load conditions are the time when room temperature approaches set temperature. For this reason, please note the following to maximise energy .

When selecting indoor units

      Indoor units are installed in a system so that they operate largely under the same conditions.

      Energy efficiency decreases for the installation patterns shown below.

      Example:

  1. A load imbalance occurs because an indoor unit in the same system is installed near the perimeter of the room or in the vicinity of a room entrance.
  2. Different operating hours for indoor units.

 

Time of Use

  1. Energy efficiency decreases when the set temperature of a specified indoor unit is excessively lowered during cooling operation.
  2. The airflow rate setting is set to "Auto" during VRT Smart Control.
