8. TESTING & COMMISSIONING PROCEDURE FOR VRV SYSTEM WITH

REFRIGERANT R 410A

When installing equipment using R410A refrigerant, there are a number of standards that must

be met:

Ester oil is used for R410A It's important to work with absolute cleanliness

Brazing must be done with the use of Nitrogen (OFN)

The system must be evacuated thoroughly (triple evacuation)

A strength test in accordance with BS EN378 must be carried out The system must always be

charged in the liquid phase.

of 91

Pressure Testing After brazing the system has to be checked for any leakages and arrest the same , Complete leak

testing and proper evacuation is is must for non-condensable gases, and moisture in the systems

has to be removed. To avoid ill effect on the systems.

Pressure Testing

Visually inspect all the pipes for proper brazing, Attach a manifold valve and dry the nitrogen

gas cylinder to both suction and liquid ports of service valves.Use TEE connection for

connecting both liquid and suction service valves., Always pressurize both suction and liquid

side of piping systems. Pressurize the system in steps of 100,200,300,400 & 550psig, Check for

any leak in each step using soap bubbles, Pressure must be within 2psig after two hours.

Do a leaK test of all joints of the tubing any bubbles indicate a leak Wipe off the soap with clean

cloth. Keep the system pressurized for 12.24 Hours and check for any drop in Pressure.After

system is found to be free of leaks , release the nitrogen pressure.

II) UV Protection.

Exposed insulated pipes are prone to heavy weathering, They must be withstand summer

monsoon and winter, Providing UV Protection enhances its life manifold, UV coating must be

done bu a compound which is a specially formulated water based coating suitable for protection

of flexible thermal insulation materials against sunlight. To increase its resistance coating can be

further strengthened by sand witching a glass fiber mesh between two coats of rubber adhesive

over insulated pipes.

B. Evacuation To ensure problem-free operation of any air-conditioning system, it is crucial to carry out

thorough evacuation of the system. During the evacuation any moisture is removed from all of

the system components and the pipe work.

The importance of thorough evacuation in any refrigeration system in order to prevent the

following harmful effects:

Any non-condensable product left in the system can cause the pressure in the condenser to

increase and in turn, the compression temperature to rise.

Moisture will result in adverse reactions in the refrigerant circuit.

The polyester oils used in the R410A refrigeration systems are hydroscopic, which means that

they absorb moisture from the air.

To prevent chemical reactions in the system, any moisture must be removed at all costs. Oxygen

(air) reacts with the refrigeration unit oil and can lead to faults such as compressor failure.

To be able to remove moisture from the system it must be evaporated.

The pressure in the pipe work must be reduced to such an extent that the ambient

temperature is sufficient to evaporate the moisture.

Essential tips for good evacuation Before evacuating a system, it is essential to check for any potential leaks. Such leaks may be

discovered at brazed or flared joints. Evacuation can only start once the system has been properly

pressure tested and found to be completely leak proof.

Leak Testing in 3 steps

Step 1 3.0 bar (N2) - Test for a minimum of 3 minutes

Step 2 15.0 bar (N2) - Test for a minimum of 3 minutes

Step 3 33.3 bar (N2) - Test for a minimum of 24 hours (if using R410A)

Triple evacuation in 6 steps

Step 1 Evacuate the system to 10 'Tarr' from both service valves.

To measure the vacuum a 'Torr gauge' must be used at all times - do not use a system manifold

gauge

of 91

Step 2 Break the vacuum with OFN to 1 bar

Step 3 Evacuate to 5 'Toff'

Step 4 Repeat Steps 2

Step 5 Evacuate to the lowest pressure that the pump will achieve (2 `Torr' for 1 hour minimum)

Step 6 The rise test must then be carried out for a minimum of 30 minutes.

C. When using copper pipe work

D. The importance of correct brazing Brazed joints should only be made using Nitrogen (CFN) as without it carbon deposits are left on

the pipe surface. The carbon deposits are then washed off of the surface of the pipe when the

refrigerant is circulated and it then travels with the refrigerant. Carbon deposits can cause the

refrigerant and refrigeration unit oil to decompose, This is likely to result in operation defects

and warranty will become null and void.

Basic Brazing Process

E. Tools & Accessories

The right tools are required in to enable the refrigeration system to be properly evacuated and

dried.

These include R41 OA Manifold Gauges, Flaring Tool, Torque Wrench, Vacuum Pump,

Refrigerant Weighing Scales

A solid manifold gauge specifically used for R410A. Manifold gauges with sight

gauges should never be used due to the higher operating pressures, unless specified for use on

R41 OA.

Nitrogen Pressure Gauge (up to 160 bar) A higher range Nitrogen Regulator must be used due to the higher-pressure testing requirements

when strength testing to conform with BS EN378.

Torr Gauge. A Torr gauge to be used to provide an accurate evacuation level required.

Vacuum Pump A Vacuum pump of sufficient quality and working order to be used to pull the correct vacuum to

negate any moisture being present in the system (pump oil needs to be regularly changed). The

refrigerant manifold gauges are not suitable for measuring vacuum,

Flaring A suitable Flaring tool to be used so as-not to compromise the integrity of the copper

when flared. Torque Spanners Torque spanners must be used at all times to tighten flares in

accordance with manufacturers guidelines. Oxygen free nitrogen for brazing

OFN to be used at all times during brazing to prevent oxidation within the copper pipe work.

Oxygen free nitrogen for strength and leak test

OFN to be used for strength and leak testing with the higher-pressure regulator, Refrigerant

charging weighing scales any additional refrigerant required for the installed system must be

weighed in the liquid phase using charging scales.

Suitable vacuum measuring gauges

To determine accurately the pressure in the system and whether the desired vacuum has been

attained, a vacuum or torr meter is indispensable. A professional evacuation requires such an

instrument.

To get the best from R41 DA Use the correct tools Adhering to BS EN378

Strength test to 1.3 x Ps (43 bar)

Leak test to 1.0 x Ps (33 bar)

Observe regulations (Health & Safety at work, pressure equipment etc )

Use correct copper pipe work with appropriate wall thickness

Follow good working practice at all times (Nitrogen brazing, proper .11,1 evacuation, etc_)
