Panasonic Guide to R32

Friday, April 29th, 2016

Panasonic introduces R32, the new refrigerant reducing global warming impact.

R-32 (Difluoromethane or HFC-32), is based on methane, except that two of the four hydrogen atoms have been replaced by fluorine atoms. Hence the formula is CH2F2 instead of CH4 for normal methane.

R32 products have been introduced in to our product portfolio by both Panasonic and Toshiba Air Conditioning in both of their wall mount ranges.

Please contact CDL for further information.

Each newsletter we aim to add details on commonly asked technical questions.  This post we are looking at how to control air to air heat exchangers in a basic format. If the requirement is for the HEX to operate when an indoor unit was turned on, then this is controlled by using the RBC-SMFI accessory. External switches can be used to operate fan speed and damper.
