USA: Commercial refrigeration equipment
New energy conservation standards

The U.S. Department of Energy (DOE) is continuously updating energy conservation standards and test procedures for refrigeration and air conditioning equipment.
The expected results of these amendments is that consumers save money on their utility bills and reduce carbon dioxide emissions.

This is possible thanks to high efficiency technologies already available in the market that are constantly being improved. This paper presents the last energy conservation standards for commercial refrigeration equipment, with the purpose of facilitating to stakeholders the understanding of the regulation and how it should be applied.

Flammable refrigerants: focus on hydrocarbons

The damage caused by chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs) to the ozone layer and the fact that their synthetic alternatives, hydrofluorocarbons (HFCs), contribute to global warming, have focused attention on “green” alternative refrigerants that both are ozone-friendly and have limited or, possibly, null effect on global warming.
Among the various green possibilities (CO2, water, ammonia), hydrocarbons are one possible way forward, with both advantages and disadvantages. 
This document examines the current panorama regarding the use of hydrocarbons as refrigerants and the standards affecting their wider use.

Ecodesign and Energy Labelling
Impact on refrigeration and air conditioning products

Do you know that more than 80% of the environmental impact of a product is determined at the design and most of the costs are committed then?
On that account, Ecodesign Directive is actively working in the definition of new regulations that will result in more efficient and “green” products.
Chillers, ventilation units, condensing units and refrigeration cabinets are among the products affected, with a high percentage of units going out of the market unless they are accordingly redesigned. This document aims to summarize the new mandatory requirements for these applications, with the purpose of facilitating the understanding to stakeholders and make it easier its application.

Refrigerant scenario
Rules and trends in the near future

Concerns on environmental issues such as the greenhouse effect are driving governments to create new rules to control emissions.
In the coming years, significant actions are planned, and refrigerants will be particularly affected. Information is continuously being updated and the specificities of regulations create many questions among manufacturers and users:
How do the rules affect the most common refrigerants? What are the trends? Which is the best refrigerant for each application?
CAREL can help you answer these questions and find solutions that are compatible with the new regulations worldwide.
