Proactive HVAC contractors have been working to educate their employees and clients on the inevitable phaseout. And, with the price of R-22 already starting to rise in many areas, educated contractors are finding it easier to convince customers to replace aging R-22 units with newer, more efficient models.
Choosing the correct line size is very important to the overall success of the installation. Incorrectly sized refrigerant lines can lead to system problems, excessive energy consumption, and higher installation and operation costs.
Supermarket owners want refrigeration systems that are energy efficient to hold down costs and pro-environmental to portray political correctness. But, for engineers, contractors, and technicians, that approach may not be that easy when opening a new store or retrofitting an existing location.
The line set flushing process can be time consuming and costly, especially if a second person is required. For that reason, ICOR International has produced a short video to demonstrate how to construct a universal looping kit that will improve line set flushing efficiency by reducing waste and making the process a one person job.
Now that we are in a new year of greatly reduced supplies of new and imported HCFC-22, it is important to note that there is no ban on the use of R-22. You can use R-22 for as long as supplies last and you have well running R-22 equipment to service.
The refrigerant landscape is preparing for a regulatory makeover. By 2018, approximately 80 percent of commercial refrigerators and ice machines will have to go through a redesign to meet new DOE standards for efficiency; the EPA is proposing to delist R-404A and R-134a in many commercial refrigeration applications; and more.
Last summer, Australia repealed its carbon tax, which, since July 2012, had been imposed on the country’s leading emitters of synthetic greenhouse gases controlled by the Kyoto Protocol. Could a tax that targets carbon dioxide emissions and refrigerants be headed to U.S. shores?
A/C Zero Leak contains no polymers, creates a permanent flexible seal, and will not harden inside the operating system, eliminating blockages and sticking problems.
Mexichem announced that its subsidiary, Mexichem Fluor, has appealed the U.S. International Trade Commission (ITC) ruling that the import of Chinese refrigerants does not harm the U.S. refrigerant gas industry.
Honeywell announced that it has started full-scale commercial production of a low-global warming potential (GWP) material used as an aerosol propellant, insulating agent, and refrigerant.
