  • Maintenance is as important as having insurance

    Why should we get our Catering, refrigeration, Chilled Water and air conditioning equipment serviced regularly?

    The benefits of having your Air conditioning and refrigeration equipment maintained are as follows:

    Air Conditioning Services by Hawkes Essex

    • Better Energy Efficiency 
      Regularly servicing your air conditioning and refrigeration equipment will help it run more efficiently. Clogged dusty air filters, dirty outdoor condenser coils and other problems mean that the system has to work harder to do maintain the temperature – using up unnecessary excess energy in the process. An inefficient air conditioning system is going to increase your energy bill and leave a larger carbon footprint on the environment. Routine servicing will result in saving you running costs and a smaller carbon footprint.
    • Longer Operational Life
      As with any major equipment, a regular service will extend your systems operational life. There’s a limit to how long any model is going to last, (generally 10 to 15 years) but the right amount of care and attention ensures that you’ll make the most of your air conditioning system. Remember that one faulty or malfunctioning part can lead to stress on other components. The sooner you fix it, the better the system will operate overall.
    • Lower Overall Repair Costs 
    • We’ve all been there. Your air conditioning system appears to be operating just fine, when – out of the blue – the entire system stops working. Suddenly, you’ve found yourself in need of costly emergency repairs. All too often, these repairs could be managed or even avoided through routine service and maintenance.

      • When you call out Hawkes Refrigeration’s Engineers to service your equipment, the technician will check for damaged or worn-down parts and recommend their immediate replacement or repair. Likewise, cleaning components such as the condensers and filters and evaporating coils will ultimately extend the life of various parts and put off the need to replace them.

      • Better Air Quality 

        Dust built up in the filter and surrounding areas results in less effective filtration this reduces the purifying of the air as it passes through. Regular service ensures that your filters and other purification methods are working as designed to original specification.

    • We can conduct TM44 compliant surveys

    All existing air conditioning systems with an effective rated cooling output of more than 12kW needs a Statutory TM44 Inspection every 5 years, or within 5 years from the systems commissioning date.

    We provide guidance on how to comply with the TM44 Inspection Regulations and deliver the TM44 inspection, certificate and report.

    Concentration Simulator

    See how nanoe™ X fills space

    nanoe™ X Concentration Simulator lets you see the distribution of nanoe™ X over time and
    learn its concentration level with expected benefits.

    Huge amount of nanoe™ X are distributed by the air flow of air conditioners and air purifier to actively fill the
    entire space. They create the certain level of concentration, based on the size of the space.

    nanoe™ X can inhibit certain bacteria and viruses, moulds, allergens, pollens, and
    hazardous substances, as well as deodorising.
    They are all invisible but pollutants are existing around you and nanoe™ X reacts on them.

    The decisive factors are the hydroxyl radicals.
    The more amount of hydroxyl radicals are generated, the more benefits are expected.

  • F-GAS Calculate the carbon dioxide equivalent quantity of an F gas

     

    Find out how to express the mass of a fluorinated greenhouse gas (F gas) in terms of CO2 so that you comply with regulations on F gases.

    Carbon dioxide (CO2) equivalent is a measure of how much a gas contributes to global warming, relative to carbon dioxide.

    You calculate the carbon dioxide equivalent of a quantity of F gas by multiplying the mass of the gas (in tonnes), by the gas’ global warming potential (GWP).

    You’ll usually find the mass of an F gas expressed in kilograms (kg) on product labels. To convert the mass to tonnes, divide by 1,000.

    See global warming potentials for F gases in the table of F gases.

    Example calculation

    The amount in tonnes of CO2 equivalent is the mass (in tonnes) of F gas multiplied by the GWP of that F gas.

    For example the global warming potential of HFC 404A is 3,922. Therefore the tonnes CO2 equivalent of 10kg of HFC 404a is calculated as follows:

    1. Mass (in tonnes) of F gas multiplied by GWP of F gas
    2. = (10/1,000) * 3,922
    3. = 39.2 tonnes CO2 equivalent

    Table of CO2 equivalent thresholds for common F gases

    For some common F gases, this table lists:

    • global warming potentials
    • the quantities that are equivalent to CO2 size thresholds used in the EU regulation

  • Refrigerant Gas R404A No Longer As Of January 2020

    Hawkes Refrigeration Engineers Limited is a registered installation and maintenance company to allow us to work with Hydro-Carbon Refrigerant gases safely.

    R404a Refrigerant Gas usage will not be allowed in new equipment after 1st January 2020

    Use of R404A

    The use of HFCs with a GWP above 2,500 will be banned in all new commercial refrigeration equipment placed on the EU market after January 1st 2020. Therefore no a/c or refrigerator/freezer manufacturer will be able to sell equipment after 1 January 2020 if it uses R404A.

    Why stop using R4040A now?

    Recently one of the largest manufacturers of refrigerants stated that they intend to stop selling high GWP refrigerants such as R404A in Europe from 2018. The price of R404A has risen dramatically over the last year!

    Legislation impacting use of R404A The revised f-gas regulations will become law from 1 January 2015. Three key areas of legislation will impact the future choice of refrigerant gas. These are:

    1. Cap and phase-down of the supply of HFCs via a CO₂ e-based quota system.
    2. Bans on the sale of new refrigeration and air conditioning equipment using higher GWP Fgases.
    3. Service and maintenance bans that will ban the use of virgin HFCs with a GWP of 2500 and above in refrigeration equipment with a charge size of greater than 40 tonnes CO2 equivalent, from 2020.

    All HFC refrigerants will be subject to the supply phase-down. However, gases with a high GWP will be more severely impacted due to their requirements for large amounts of supply quota. These gases will also be subject to additional control due to restrictions on the supply of new equipment using them, and service and maintenance bans impacting their use in existing equipment.

    R404A (GWP 3922) is the most widely used gas in the EU in stationary refrigeration systems, commonly used in low-temperature commercial systems such as those used in supermarkets. The use of R404A will be impacted by all three of the legislation measures detailed above. Therefore a solution is needed to replace this refrigerant whilst continuing to deliver the required cooling reliably and efficiently.

    Alternatives to R404a

    Using another gas in place of R404a will depend on the equipment in use and its purpose. Hawkes can advise on what to do for both new equipment and existing, please contact us if you need help

    Until now there have been three main replacements for R404A.

    Two are sister refrigerants to R407C, the initial favourite for use in unitary air conditioning systems using different percentages of the HFC refrigerants R134a, R125 and R32. Also R407A – a blend of 40% R134a, 40% R125 and 20% R32 – with a GWP of 1990.26 Feb 2014.

    R22 Refrigerant Gas is now phased out as of 1st January 2015

    If your equipment is still using R22 gas, Hawkes Refrigeration Engineers can provide a full consultancy, installation and replacement service to help make your transition to industry compliant refrigeration equipment safe, economic and efficient. Most importantly,
    the careful and safe removal of the R22 and its integral chemicals is foremost to an effective exchange.
