New type of AC replaces refrigerant with water
A multidisciplinary team at Harvard University is working on a design for a new type of air conditioner that it says uses a fraction of the energy typically needed by current models. The device uses water in place of refrigerants. Dubbed ColdSNAP (SNAP stands for “superhydrophobic nano-architecture process”), the design incorporates a coating that, inspired […]
IOR releases refrigerant selection guide
The Institute of Refrigeration (IOR) has released a new Guidance Note, a guide to refrigeration selection. The guide aims to provide an overview of the critical points that should be considered in selecting refrigerants. The IOR says the guide, which it refers to as Guidance Note 37, will be of particular interest to equipment owners, […]
RRA offers $10 a kilo for recovered refrigerant
Refrigerant Reclaim Australia (RRA) is increasing the rebate for recovered refrigerant rebate to $10 per/kg as part of the Gas Seeker Initiative. The new rate, which will apply from January 1 to June 30, 2021, is more than triple the current rebate of $3 per kilogram. RRA says that the initiative is intended to give […]
RRA launches augmented reality app
Refrigerant Reclaim Australia (RRA) has released a series of new digital training resources that provide an innovative and hands-on way for apprentices to understand the refrigerant recovery processes for various types of equipment. “The processes for recovering refrigerant, pressure testing, evacuating and re-charging systems are critical for both upholding industry best practice and reducing the […]
Cash for refrigerant data
Refrigerant Reclaim Australia (RRA) is seeking help from HVAC&R technicians to better understand what happens to refrigerant from split system air conditioners when they are replaced. And it is paying for the data. RRA is a not-for-profit organisation that works with industry to recover, reclaim and destroy surplus and unwanted refrigerants. The organisation is offering […]
Free refrigerant course offers certification
REAL Alternatives 4 Life is a free online course that provides education on the safe use of alternative refrigerants such as ammonia, hydrocarbons and carbon dioxide. The course was developed in response to the European F-Gas Regulation, which encourages wider adoption of refrigerants with a lower global warming potential (GWP). The program is now offering […]
Free online refrigerant course
Industry groups have joined together to create a free online course called Real Alternatives 4 Life, to provide education on the safe use of alternative refrigerants such as ammonia, hydrocarbons and carbon dioxide. The course has been developed in response to the European F-Gas Regulation, which encourages wider adoption of refrigerants with a lower global […]
The new successor to R410A?
The American Society of Heating, Refrigerating and Air Conditioning Engineers (ASHRAE) has given Honeywell’s new stationary air conditioning refrigerant R466A (also known as Solstice N41) the official designation A1 – non-toxic and non-flammable. The classification could be a key factor for manufacturers deciding which refrigerant to use in their systems in the medium-term. As a result of […]
Crackdown on refrigerant offences
The Department of the Environment and Energy has issued a number of fines for offences under the Ozone Protection and Synthetic Greenhouse Gas Management Act 1989. A New South Wales-based refrigeration mechanic has been fined $2,520 for discharging R410A while installing an air conditioning system. According to the Department, the offender holds a permit issued […]
