SUPERMARKET REFRIGERATION
m ost energy efficient cabinet to date. Designed specifically for forecourts and
convenience stores the new remote Eco-Lichfield will lead the way in refrigeration design and energy efficiency within the refrigeration cabinet sector. The ETL listed product was independently t ested by an ECA accredited Assessor.
The new Eco-Lichfield range has been designed taking into account the fact the cabinets will be designed with doors, sliding or hinged and with duties/loadings calculated, which means the efficiencies of the chilled cabinets far exceeds w hat is currently the norm, resulting in the new E co Lichfield chilled cabinets having an energy rating label (A).
This is predominantly due to the evaporator coil being designed and sized for the specific volume of a chilled cabinet with doors and not making allowances in duties/loadings for a chilled cabinets that may or may not have doors fitted at the request of the customer.
Compressors are a vital element in cooling appliances, ensuring that the entire system runs smoothly and efficiently. The effectiveness of a compressor is the optimization of all components, i ncluding motor type and inverter type.
Variable speed compressors have a number of
a dvantages over fixed speed alternatives, mainly because they can be adjusted to cover a broad r ange of refrigeration loadings/demands on the s ystem
When using a variable speed compressor with an inverter in a refrigeration system, it is possible to lower the condensing temperature. In addition, a high evaporator temperature at low load rate c an be applied so that when a refrigeration s ystem isn’t fully loaded the compressor will w ind-down and not have to work as hard to keep items chilled. This can result in energy consumption savings when compared against refrigeration systems that utilize a fixed speed compressor.
T he positioning of any new external
r efrigeration plant on most MCC Sites can and often does present its own issues as most MCC stores are surrounded by residential dwellings with very limited options for external refrigeratio n plant and stringent local noise emission controls. With the extraction rates quoted by The Bond G roup we are able to offer much smaller external refrigeration plant to service the new Eco Lichfield Chilled cabinets which directly offers more external plant positioning options and flexibility for remote refrigeration systems.
Overall, a variable speed drive compressor offers engineers far more options by altering the settings for each individual device built, efficiency gains can be made that both benefit a business and the customer.
The initial investment might be slightly higher by specifying a compressor with inverter but the operating costs and therefore the total cost of ownership will be significantly lower. Especially in high priced energy markets, the payback time is extremely short.
The New Eco Lichfield remote chilled cabinets have significantly reduced extraction rates on what is currently the norm, this directly changes the interconnecting pipe sizes, which is also a cost saving for the customer and also brings more options to the on-site installation teams when routing smaller sized pipework and less intrusive to the structural fabric make-up of the building.
24-Seven Cooling also found a significant saving on the refrigerant cost and the
total volume of refrigerant that went into the system, with all these gains from both the Eco- Lichfield and the chosen inverter condensing unit were the perfect combined package for MCC.
