Preface
This manual specifies safe operation requirements for GMV5 series VRF units from perspectives of
engineering and installation, commissioning and maintenance, as well as basic principles and implementation
methods. Professional operators must abide by relevant national (local) safety requirements and technical
specifications set forth in this manual during operations; otherwise, the air conditioning system may fail or be
damaged, and personnel safety accident may also occur.

Chapter 1 Introduction to Basic Features of
Units
1 Basic Operating Principle
Outdoor unit of VRF unit can be connected through module combination in parallel, and indoor unit can
also be connected by multiple units in parallel. The operating principle: Under different modes, the pipes of
heat recovery VRF unit won’t change according to the change of mode exchanger. It will provide three kinds of
stable refrigerant (high pressure, medium pressure and low pressure) for system. Indoor unit will automatically
adjust the refrigerant flow direction to realize heating and cooling according to its operation status and through
mode exchanger and other devices.

2.4 Names and Main Functions of Components
No.
Name
Main Function
1
Compressor
Adjusts its own rotational speed based on the actual
requirement of the system to implement capacity control.
2
Compressor heat tape
Maintains a proper oil temperature in the compressor when
the compressor is in standby status, ensuring the reliability
during compressor startup.
3
High-pressure circuit breaker
Protects a compressor by sending feedback signal to stop the
system when the compressor's discharge temperature
exceeds the operating value of high-pressure circuit breaker.
4
One-way valve
Control refrigerant flow direction, preventing its counterflow.
5
Oil extractor
Separates the gas and oil in the system to ensure compressor
reliability.
6
Four-way valve
Used for the switching between the cooling and heating
functions of system IDU.
7
Filter
Prevents impurities from entering components and parts.

6
8
High-pressure sensor
Detects the high pressure value in the system in real time
mode for compressor protection and other control functions.
9
Low-pressure sensor
Detects system low pressure to avoid extra-low operating
pressure.
10
Fan
Strengthens heat exchanging.
11
Electronic expansion valve for heating
Controls refrigerant adjustment in heating mode.
12
Sub cooler electronic expansion valve
Controls the degree of sub cooling of tube refrigerant when
the system is running in cooling mode, and reduces the
capacity loss on pipes.
13
Sub cooler
Controls the degree of sub cooling of tube.
14
Dry strainer
Avoid impurities getting into the electric parts. Meanwhile,
absorb the water inside the liquid status to prevent ice
blockage.
15
Unloading valve
Opening if the pressure inside the liquid pipe is too high.
16
Refrigerant adjustment tank
Adjust the system refrigerant circulation volume.
17
Gas-liquid separator
Separate gas and liquid to prevent the system from running
when the refrigerant flows back to the compressor.
18
High pressure gas pipe valve
Stop valve, closed when the unit is delivered from the factory
and will be opened after installation.
19
Liquid valve
Stop valve, closed when the unit is delivered from the factory
and will be opened after installation.
20
Low pressure gas pipe valve
Stop valve, closed when the unit is delivered from the factory
and will be opened after installation.
21
Low-pressure measurement valve
Detects the low pressure value or charges refrigerant during
system running.
23
Capillary tube
Supports flow regulating and pressure reduction.
24
Heat exchanger
Used for outdoor heat exchange.
25
Oil return solenoid valve
Oil return control for the compressor
26
Gas-bypass valve
Make sure pressure of the system is balanced
27
High height difference valve
It‘s the pressure-drop device when the height difference
between indoor unit and outdoor unit is big.
28
Pressure-balanced valve
Ensures success startup of compressor.
29
Pressure valve
Pressure control valve for refrigerant adjustment tank
30
Liquid intake valve
Liquid intake control valve for refrigerant adjustment tank
31
Pressure balance valve
Press control valve inside the refrigerant adjustment tank
32
Drain valve for cooling
Drainage control valve for cooling of refrigerant adjustment
tank
33
Drain valve for heating
Drainage control valve for heating of refrigerant adjustment
tank
34
Compressor casing-top temperature
sensor
Detects a compressor's exhaust gas temperature for
compressor control and protection.
35

Used for defrosting detection.
37
Liquid outlet temperature sensor of sub
cooler
Detects tube temperature.
38
Gas outlet temperature sensor of sub
cooler
Detects gas temperature of sub cooler.
39
Inlet temperature sensor of gas-liquid
separator
Detects the inlet temperature of gas-liquid separator to
prevent the system from running when the refrigerant flows
back to the compressor.
40
Outlet temperature sensor of gas-liquid
separator
Detects internal status of gas-liquid separator to further
control the compressor suction performance.

3.2 Basic Parameters for Mode exchanger
The exchanger of heat recovery heat recovery mode is used for connecting outdoor unit and indoor unit,
and providing high pressure, low pressure and medium pressure refrigerant provided by outdoor unit for
cooling or heating mode and complete the refrigerant system circulation for the purpose of adjusting indoor
temperature.
(1) The exchanger of GMV5 HR heat recovery mode provides multiple branch combination forms, which can
connect different kinds of lower branches. Each branch of the exchanger of heat recovery exchanger can
connect 8 indoor units at the most and the total capacity should be no more than 14.2kw.
(2) The exchanger of GMV5 HR heat recovery mode provides multiple branches used for connection lower
indoor units. It’s convenient for installation, leakage detection and maintenance.
(3) The exchanger of GMV5 HR heat recovery mode is supplied power independently, which connects indoor
unit and outdoor unit with communication wire. It’s convenient and flexible for installation and construction.
