• • MRV AHU Connector
  • System Overview

• • An MRV AHU connector is an interface device that allows third-party air handling units (AHUs) to be connected to a multi-connection VRF (variable refrigerant flow central air conditioning system), such as the Haier MRV system. The system has the following characteristics:
  • Expand the connection capacity of the AHU per kit from 3.5 kW to 73 kW, meeting the needs of small, medium, and large buildings.
  • Add 0-10V signal control function.
  • The feed air temperature (from DDC) or return air temperature is adjustable.
  • Dismantle the gas pipeline, it will be more convenient for installation.
  • For Haier’s third-generation air handling unit (AHU): AH1-***C, the following new features are added: 01. Can be connected to a third-party CO2 sensor 02. Has an emergency stop function 3. Equipped with fault warning and fault display function 4. Can be linked to a fresh air supply system

• • Product Description
  • The Haier AHU kit offers a variety of solutions for connecting Haier MRV outdoor units to a third-party AHU.

• • Solutions for apartments or hotels that use their own resources
  • Model HA-AA110AD
  • The HA-AA110AD is Haier’s Communication Amplifier/Repeater, used in the MRV central air conditioning system. Main purpose
  • Amplify and clean the communication signal on the control line between the outdoor unit and the indoor unit.
  • Help the system transmit signals stable when the line is long, avoiding loss or communication errors.
  • Used when the communication distance exceeds about 200 m or the system is large-scale
  • Up to 2 sets of HA-AA110AD can be used in one system.
  • When using a repeater, the maximum SpaceLink communication distance can be up to 600 m.
  • One system support kit with up to 30 indoor units
  • Model MTC-001
  • MTC-001 is a module that protects/maintains the Standby state for the indoor unit when the power supply of the indoor unit is forcibly disconnected. When an indoor unit loses power, the MTC-001 supplies DC power to the PCB of the indoor unit so that the board remains in the Standby state. At the same time, the throttle is closed and the control signal is blocked, so that the MRV system does not report a loss of connection to the indoor unit and avoids affecting the operation of the whole system
  • It is especially useful in:
  • The building has many households that use their own circuit breakers: each indoor unit has its own CB, which the tenant can disconnect the CB himself.
  • Hotel: the key-tag system can directly cut off the power to the indoor unit when guests leave the room.
  • Accessories:
    • Gas divider

• • Function: Used to branch, divide or consolidate refrigerant (gas) pipes connecting outdoor units in the Haier MRV central air conditioning system.
  • Application: Installation in commercial and industrial air conditioning systems such as buildings, offices, commercial centers, workshops.
  • Maximum number of connections: Supports connecting up to 2-4 outdoor units in a group
  • Models: HZG-20A, HZG-30A, HZG-20B, HZG-30B, HZG-R20A, HZG-R30A, HZG-R20B, HZG-R30B, HZG-R40B are used to divide the gas outdoor unit.
  • Model: FQG-B335A (max allowable connection 33.5KW), FQG-B506A (max allowable connection 50.6KW), FQG-B730A (max allowable connection 73KW), FQG-B1350A (max allowable connection 135KW), FQG-B2040A (max allowable connection 204W), FQG-R335A (max allowable connection 33.5KW), FQG-R506A (max allowable connection 50.6KW),  FQG-R730A (maximum connection allowed 73KW), FQG-R1350A (maximum connection allowed 135KW), FQG-R2040A (maximum connection allowed 204KW) are used to divide the gas for the indoor unit.
  • VP box
    
  • Haier’s VP Box (Valve Pipe Box) is a control device used in commercial VRF air conditioning systems that have a heat recovery function, allowing different rooms to simultaneously perform cooling and heating modes. Functions of VP Box:
    • Simultaneous operation (allows one indoor unit to cool while another unit heats on the same outdoor unit system)
    • Refrigerant coordination (manages the flow of high-pressure gases, suction gases, and liquid refrigerants in a 3-pipe system)
    • Zone control (connects to multiple indoor units via electronic valves to control the temperature independently in each zone).
  • Main features:
    • Connectors (single-port or multi-port options available – e.g., 4-port type – to support multiple indoor units)
    • System compatibility (specifically designed for Haier MRV – Multi-Refrigerant Volume heat recovery outdoor units)
    • Valve system (uses a built-in electronic throttle to precisely regulate refrigerant pressure and flow).
  • Model: VP1-112A, VP1-180A, VP1-280A, VP1-112C, VP1-180C, VP1-280C, VP4-450A, VP4-450C

 

• • Shut off box
  • Haier’s SVP-160A is an automatic shut-off valve for VRF central air conditioning systems (such as the Haier MRV7 S R32 VRF System).
  • Main Functions
    • Leak Isolation: Automatically locks and shuts off the circuit area with a refrigerant leak (R32 refrigerant gas) when a problem is detected.
    • Stay Operational: Helps keep other areas or indoor units in the system operating properly without having to shut down the entire network.
    • Safety: Coordinate with the built-in leak sensor system on the indoor unit to trigger alarms and emergency handling

  • With Haier’s MRV selection software, engineers and consultants can easily design, layout, and prepare a complete MRV system for quotation in just a few steps. The software will automatically select models that match the building’s load requirements and calculate piping and wiring diagrams automatically or manually. Drawings can be imported in dwg or jpg format. The selection software will guide you through compliance with the design rules and provide a comprehensive system design report in pdf, word, or excel format.
  • TD-03 service tool with monitoring software
    
  • Installation technicians can use the TD-03 service tool together with the monitoring software to realize real-time monitoring of the operation data of the VRF system through a computer. The operation data and parameters can be used for fault analysis for quick troubleshooting. You can also save the data for further analysis.
