The refrigeration industry has been working overtime by lobbying MEPs to relax the targets set by the European ENVI committee in June.

Refrigeration bodies throughout Europe such as ACRIB, BRA, EPEE and AREA have combined their strengths and say they are redoubling efforts to convince European policymakers that the proposals from the European Parliament ENVI Committee (Environment, Public Health and Food Safety) agreed last week are too stringent.  Here, we publish an article that RACPlus featured as the news hit:

Call for compromise on F-Gas Targets

Refrigeration bodies believe that compromise is needed to ensure that the refrigeration, air conditioning and heat pump industry does not bear the brunt of costs for an accelerated phase-down of HFCs and early new equipment bans in key sectors, from large refrigeration systems to air conditioning.

As it stands, the following key bans to equipment ‘placed on the market’ in Europe have been proposed:

  • Ban on stationary refrigeration equipment containing F-gases with GWP of 2500 or more from 1 January 2016 (except equipment intended for use at operating temperatures of below -50 deg C)
  • Ban on stationary refrigeration equipment containing any F-gases from 1 January 2020  (except equipment intended for use at operating temperatures of below -50 deg C)
  • Ban on stationary air conditioning equipment containing F-gases from 1 January 2020
  • Ban on for commercial refrigerators and freezers, containing HFCs with GWP of 2150 (down from 2500 in original Commission proposal from 1 January 2015 (instead of 2017).
  • Ban on commercial refrigerators and freezers containing HFCs in general from 1 January 2018 (instead of 2020 and original threshold of GWP removed)
  • Ban on AC equipment in cargo ships containing F-gases as of 1 January 2020
  • Ban on mobile refrigeration equipment containing F-gases from 1 January 2025

The ENVI committee has made amendments which appear to take energy efficiency into account when applying the ban but at the same time, it has tightened the criteria so it applies to total lifecycle emissions.

A Guide to Common Refrigerants and Ozone Depletion Potential (ODP) and Global Warming Potential (GWP) are indicated below.

  • Ozone Depletion Potential (ODP) of a chemical compound is the relative amount of degradation it can cause to the ozone layer.
  • Global Warming Potential (GWP) is a measure of how much a given mass of a gas contributes to global warming. GWP is a relative scale which compares the amount of heat trapped by greenhouse gas to the amount of heat trapped in the same mass of Carbon Dioxide. The GWP of Carbon Dioxide is by definition 1.

A new research centre combining the HVAC expertise of four British Universities has been created to develop cost-effective and energy-efficient heating and cooling technologies.

The project, led by London South Bank University (LSBU), who successfully secured funding from the Engineering and Physical Sciences Research Council (EPSRC) to investigate how to reduce UK energy consumption from cooling systems by 2050.

The £1.2 million funding is part of a £5.25 million project, led by the University of Warwick, to investigate heating, cooling and heat storage. The goal of the project is to minimize future greenhouse gas emissions and energy consumption.

With more than 40 per cent of fossil fuels used for low temperature heating and 16 per cent of electricity used for cooling, these are key areas to address if the UK is to meet its targets of reducing greenhouse gas emissions by 80 per cent by 2050.

The Interdisciplinary centre for Storage, Transformation and Upgrading of Thermal Energy (i-STUTE), which will house the project, will also bring together technologists from the University of Ulster and Loughborough University.

The collaborating institutions working will work in the i-STUTE to develop technologies to reduce energy consumption and deliver cost-effective heating and cooling.

LSBU's team will consist of Lecturers and Researchers from the Faculty of Engineering, Science and the Built Environment, including Dr Deborah Andrews, Dr Issa Chaer, Dr Gareth Davies, Dr Alex Paurine, Professor Judith Evans, and Professor Graeme Maidment.

Professor Graeme Maidment said: "Cooling is an important technology for many things we take for granted, it is critical to food manufacture, development of pharmaceuticals and chemicals, as well as keeping datacentres and the internet servers cool.

As a large user or electricity and greenhouse gas producer, it is essential that we develop better cooling technologies for the low carbon economy. This project will provide new technologies and knowledge to enable industry to adapt and meet future challenges."

Minimising the heat gains on refrigerated cabinets and cold rooms cuts the cooling load on your refrigeration system and saves you energy and money.

Any energy efficiency initiative dealing with refrigeration should start by reviewing the heat gains on your system.  If you understand the nature of these gains, you’ll be able to manage the amount of cooling that needs to be done and make energy savings. Heat gains include warm air entering the cabinet or cold room and heat produced by electrical equipment within the cooled space.

This guide covers in detail two opportunities to reduce heat gains: reducing cold air changes using strip curtains, and using EC (electronically commutated) replacement motors for evaporator fans.

The business case - You will find opportunities for reducing heat gains on refrigerated cabinets and cold rooms in most applications.  Improving door management in cold rooms results in substantial energy savings. For example, installing plastic strip curtains to a cold room can give savings of up to 30%, and have a payback period of around a year.

Replacing conventional shaded-pole fan motors with equivalent EC motors can cut their energy use by 65%, as well as generating less heat and reducing your maintenance replacements.  You can maximise the saving achieved by fitting a whole new fan assembly instead of just replacing the motor. In most applications the payback period for fitting EC motor fans is one to two years, but it can be much shorter.

Reducing the heat load on your existing large refrigeration systems can save energy and cut your running costs. It can also reduce the capital cost of a new plant and even eliminate the need to invest in a new plant altogether.

This guide is aimed at users of existing large refrigeration systems such as those in supermarkets, central air conditioning systems, large cold stores and large industrial processes. It will help you to minimise your cooling needs and to meet them as efficiently as possible using the most suitable refrigeration system.  Both of these will result in energy savings.

Before you start any refrigeration energy efficiency initiative it is vital to review the heat loads on your cooling plant. If you understand the nature of your loads you can make sure they are met while at the same time minimising the energy cost of your refrigeration systems.

The business case - There are opportunities to reduce the heat load on refrigeration systems at almost all sites.  Savings and costs will vary depending on the type of opportunity.  Often payback periods are less than one year, and sometimes even no-cost heat load reductions are possible.

If you are planning to install a new plant, reducing its heat load could reduce the capital cost. If your existing refrigeration system currently struggles to supply enough cooling, reducing the heat load on your system could avoid the need for an expensive new plant altogether.
