- Points to bear in mind at the system design sien34 705
- How these installation problems affect an equipment are shown below
- General information
- The installation is of vital importance
- Striking a balance between system installation and general construction work comprehensive flow chart
- Note 1 the division of the work should be thoroughly clarified this applies particularly to work relating to the connection of control wiring fitting of remote control and central control panel boundary work on areas such as connection of drain piping and humidification supply piping inspection and foundation 2 keep a constant check on the progress of the construction work to avoid deviations from the air conditioning work schedule 3 for sleeve and insert work the positions of ceiling girders should be confirmed and sleeve and insert requirement hole diameters positioning and numbers decided this is particularly important in the case of sleeves for drain piping
- The following points should be borne in mind when preparing the contract drawings from the original drawings and the execution drawings the contract drawings for the air conditioning system are blueprints for the performance of the necessary work which are drawn up on the basis of the original drawings in such a way that a working balance is achieved between the specific requirements of each individual aspect of the work
- The following is a list of the main points to be considered when preparing contract drawings for the iii system and should be used as a reference during this stage of the work
- Points to bear in mind when preparing the contract drawings
- Objectives include the drawings should be easily comprehensible to those carrying out the work the contents of the drawings should not be subject to subsequent alteration
- Contract drawing
- At the contract drawing stage the following points are critical
- Sien34 705 points to bear in mind at the system design
- Note with the vrv iii r 410a heat pump cooling only series unit no is determined through automatic addressing therefore readout unit nos after activating the power
- Mark each outdoor unit with a code 2 add field settings and data for outdoor units and outdoor unit no if using sequential start 3 add the model number of each indoor unit connected to each refrigerant circuit 4 assign each indoor unit a code 5 fill in the location of each indoor unit 6 group indoor units controlled by one or two remote controls group or individual control 7 assign central group nos if using centralized control 8 add field settings and optional equipment for indoor units 9 add unit no if making separate field settings for each indoor unit under group control
- Main considerations in preparation of control circuit diagrams
- In addition to the design of the appropriate this system configuration it is also essential that the control system be made amply clear if the system is designed and installed without a clear comprehensive plan then problems are inevitably going to occur during the test run servicing too will become much more time consuming than necessary however if control circuit diagrams are prepared along with the contract drawings in order to make the total system clearly visible then the essential points relating to the electrical connections will be easily understood the test run will go off without a hitch and the whole system will be rendered fully effective

- Flare gauge adapter corresponding to the new rank when using the later use a flare gauge to take out the pipe from the gauge bar adjust it and then carry out the flare processing
- Flare connection
- D coat the inner and outer surface of the flare with refrigerator oil ester or ether oil this ensures that the flare nut passes smoothly preventing the pipe from twisting do not use suniso 4gs oil
- A stiffened pipe must always be annealed at least once prior to the flaring work b a pipe cutter must be used to cut the pipe a large pipe cutter must be used where the pipe has a large diameter when cutting a pipe which is too big for the pipe cutter a metal saw may be used but care must be taken to ensure that the debris from sawing does not get into the pipe c set the flaring tool to make sure the flare size remains within the prescribed limits
- Size from the dice surface to the copper tip in mm
- New rank compatible flare tool compared to previous refrigerants the components of a hfc refrigerant is small r 410a also has a higher pressure than other refrigerants therefore in order to strengthen the intensity of the form and size of the flare section used for r 410a class 2 apparatus unlike the specification of the conventional refrigerants it was set up with different standards when carrying out flare processing use a new rank compatible flare tool or a conventional flare tool

- General information
- Checking for leaks
- Check 2 when searching for a minor leak or when there has been a fall in pressure while the system has been fully pressurized but the source of the leak cannot be traced 1 release the nitrogen until the pressure reaches 0 mpa 2 increase pressure to 1 mpa using gaseous flon gas r 410a nitrogen and flon gas mixed 3 search for the source of the leak using a leak detector 4 if the source of the leak still cannot be traced then repressurize with nitrogen up to 4 0mpa and check again the pressure must not be increased to more than 4 0mpa
- Check 1 where pressure falls while carrying out steps 1 to 3 described on previous page check by ear listen for the sound of a major leak check by hand check for leak by feeling around jointed sections with hand soap and water check snoop bubbles will reveal the presence of a leak
- Key points lower the degree of vacuum to below 755mmhg
- What is vacuum drying
- Vacuum drying is the use of a vacuum pump to vaporize gasify the moisture liquid inside the pipes and expel it leaving the pipes completely dry inside at 1 atm 760 mmhg the boiling point evaporating temperature of water is 100 c but if a vacuum is created inside the pipes using a vacuum pump then the boiling point is rapidly reduced as the degree of the vacuum is increased if the boiling point is reduced to a level below that of the ambient temperature then the moisture in the pipes will evaporate
- Vacuum drying
- The evacuation of air conditioner piping provides the following effects 1 vacuum drying 2 removes air and nitrogen used in air tightness test from the inside of pipes therefore it is necessary to ensure that the both purposes have been achieved in the vacuum drying operation
- Choosing a vacuum pump
- When selecting a vacuum you should select one which is capable of achieving 0 torr of ultimate vacuum
- Vacuum pump maintenance because of their nature most vacuum pumps contain large amounts of oil which lubricates bearings etc and functions to enhance airtightness of pistons when using a vacuum pump to discharge air from refrigerant piping moisture in the air tends to get mixed in with the oil you must therefore change oil periodically and make sure the proper oil level is maintained perform periodic inspections in accordance with the operating instructions
- Sien34 705 installation
- General information 41
- Degree of vacuum measurement an extremely accurate vacuum gauge is required to test degree of vacuum you cannot accurately measure degree of vacuum with the compound gauge on the gauge manifold a pirani vacuum gauge is required to measure degree of vacuum accurately because pirani gauges are very sensitive and require extreme care when using they are not very suitable for use in the field you should therefore use the pirani gauge to calibrate the attached vacuum gauge on the gauge manifold and the degree of vacuum of the vacuum pump
- Degree of vacuum is expressed in torr micron mmhg and pascal pa the units correlate as follows
- 2 degree of vacuum ultimate vacuum varies largely according to use of the vacuum pump vacuum pumps used for vacuum forming cannot be used for vacuum drying a vacuum pump with a high degree of vacuum is required
- Many handy pumps fall into this category
- Installation sien34 705
- General information
- Calibration method 1 connect a pirani vacuum gauge and the gauge manifold vacuum gauge 0 760 mmhg to the vacuum pump at the same time and run the pump for about 3 minutes 2 make sure the reading of the pirani vacuum gauge is 5 torr 667 pa or less the reading of conventional vacuum pumps lowers to about 0 torr if the reading is not 5 torr or less check the vacuum pump oil oil is low in many cases 3 check the attached gauge on the gauge manifold adjust the gauge if the reading is not exactly correct 4 adjust the gauge manifold valve so that the pirani vacuum gauge reads 5 torr 5 mark the position indicated by the gauge manifold gauge with an oil based ink pen 6 use the mark of the gauge manifold as a target when vacuuming in the field

- The pipework should be kept as short as possible and the number of indoor units per group kept to a minimum
- It is standard work practice to make connections to the main pipe from above the pipe down from the combination should be as large as possible
- Installation sien34 705
- Important points 1 the drain pipe should be at least equal in size to that of the indoor unit 2 the drain pipe is thermally insulated to prevent the formation of condensation inside the pipe 3 the drain up mechanism should be fitted before the indoor unit is installed and when the electricity has been connected some water should be added to the drain pan and the drain pump checked to see that it is functioning correctly 4 all connections should be secure special care is needed with pvc pipe the use of a colored adhesive with pvc pipes will help you to remember to connect them up
- If a drain pan made of polystyrene foam is used then an auxiliary drain hose flexible is also essential a flexible drain hose permits the drain socket and drain pipe to be connected without difficulty and prevents any undue strain being placed on the drain pan
