Why R22 renewal?

An important drive to further reduce the potential damage to our ozone
It is often said that legislation is ruling our lives but sometimes it is there to help save lives. R22 phase out can be described as one of these and from Jan 1st 2010 the use of Virgin (new) R22 refrigerant was banned within the European Community.

Panasonic are doing our part
We at Panasonic are also doing our part – recognising that all finances are under pressure at the moment. Panasonic has developed a clean and cost effective solution to enable this latest legislation to be introduced with as minimum an effect on businesses and cash reserves as possible.
The Panasonic renewal system allows good quality existing R22 pipe work to be re-used whilst installing new high efficiency R410A systems.

By bringing a simple solution to the problem Panasonic can renew all Split Systems and PACi systems; and depending upon certain restrictions we don’t even limit the manufacturer’s equipment we are replacing. 

By installing a new high efficiency Panasonic R410A system you can benefit from around 30% running cost saving compared to the R22 system. The installation can also qualify for the government’s ECA (Enhanced Capital Allowance Scheme) which enables you to offset the cost against your Capital Gains Tax.

1. Check the capacity of the system you wish to replace
2. Select from the Panasonic range the best system to replace it with
3. Follow the procedure detailed in the brochure and technical data Simple...

R22 - The reduction of Chlorine critical for a cleaner future
Reuse of existing piping (Renewal Design & Installation)
Notes on Reuse of Existing Refrigerant Piping
It is possible for each series of PE1 type and PEY1 type outdoor unit to reuse the existing refrigerant piping without cleaning when obtained a certain condition. Make sure that the requirements under the section “Notes on Reuse of Existing Refrigerant Piping”, “Measurement Procedure for Renewal” and “Refrigerant Piping Size and Allowable Piping Length” will be satisfied in order to carry out . Also, check the items with regard to section “Safety” and “Cleaning”. 
1. Prerequisite
  • If the refrigerant used for the existing unit is other than R22, R407C and R410A, the existing refrigerant piping cannot be used.
  • If the existing unit has another use than air conditioning, then existing refrigerant piping cannot be used.
2. Safety
  • If there is a hollow, crack or corrosion on the piping, make sure to install new piping.
  • If the existing piping is other than capable of reuse of piping as shown in the flowchart, make sure to install new piping.
  • In case of multiple operation type, use our genuine branch piping for refrigerant R410A. 
A local supplier shall assume responsibility for the defects and hollows on the reuse of existing piping surface and recognition of reliability of the piping strength. There is no guarantee that we take responsibility for such damages. The operational pressure of the refrigerant R410A becomes higher compared to R22. In the worst case, a lack of compressive strength may lead to piping explosion.

3. Cleaning
  • When the refrigerant oil used for the existing unit is other than the listed below, make sure to install new piping or wash it thoroughly before reusing it.
    [Mineral Oil] SUNISO, FIORE S, MS
    [Synthesized oil] alkyl benzene oil (HAB, parallel freeze), ester oil, ether oil (PVE only) 
If the existing unit is GHP type, it is necessary to wash the piping thoroughly.
  • If the existing pipes in the outdoor and indoor units remain disconnected, make sure to install a new piping or wash it thoroughly before reusing it.
  • If the discolored oil or residue remains in the existing piping, make sure to install a new piping or wash it thoroughly before reusing it. See “Deterioration Criteria for Refrigerant Oil” in table 3.
  • If the compressor of the existing air conditioner has a failure history, make sure to install a new piping or wash it through thoroughly before reusing it. 
When reusing the existing piping as it is without removing dirt and dust, inadequate piping could result a renewal appliance in failure.
Notes on Renewal for Simultaneous Operation of Multiple Units
Only main pipe is applicable for using the different diameter size. In case of different diameter size for the branch pipes, a new installation work for a standard size is necessary. Be sure to use our genuine branch piping for refrigerant R410A.
  • Only the main pipe L can be used among different diameter’s existing piping.
  • Installation work as a standard size is capable for L1, L2, ℓ1 - ℓ4 piping.
  • Be sure to use our genuine branch piping for refrigerant R410A. 
1. In case of single unit
It is not necessary to charge with additional refrigerant until the charge less pipe length in the table 2.
If the pipe length is exceeding the charge less pipe length, charge with additional refrigerant amount per 1 m according to the equivalent length.

2. In case of simultaneous operation of multiple units
Calculate the refrigerant charging amount according to the calculating method of the standard piping diameter.
As to the additional refrigerant charging amount per 1 m, refer to the additional amount in the table 2.

Notes on Renewal for Simultaneous Operation of Multiple Units
Capacity class (Standard piping size):
  • Type 50: Ø6.35 Liquid pipe / Ø12.7 Gas pipe 
  • Type from 60 to 140: Ø9.52 Liquid pipe / Ø15.88 Gas pipe 
  • Type 200: Ø9.52 Liquid pipe / Ø25.4 Gas pipe 
  • Type 250: Ø12.7 Liquid pipe / Ø25.4 Gas pipe

Refrigerant Piping Size and Allowable Piping Length
Check if reuse of existing refrigerant piping is possible based on the following chart. The standards other than this one (difference of elevation, etc.) are identical to the requirements of ordinary refrigerant piping.

Table 2 - 1 Refrigerant piping size: 3.6 - 14.0 kW type (mm)
How to see table definition (example):
In case of type 71, standard size is liquid pipe Ø9.52 / gas pipe Ø15.88.
There is a limitation to liquid pipe Ø9.52 / gas pipe Ø12.7and to liquid pipe Ø12.7 / gas pipe Ø15.88.
However, they are applicable for different diameter’s pipes.

Table 3 Deterioration Criteria for Refrigerant Oil
Renewal / Replacement Technology 
  •  Test should also be carried out to ensure the oil within the system is not acidic.
  • Most kinds of test kit are acceptable including suction line tests.
  • If the system has had a history of burnouts it is more than likely the system will not be a good candidate for a renewal/replacement technology.
