Chiller Unit Energy Saver

Refrigeration systems account for around two hundredth of the world’s energy consumption and that we have extended sensible expertise to demonstrate there's real potential to realize dramatic reductions in energy prices - improve instrumentality performance and dependability - at constant time providing additional correct management of the temperature of hold on food product.

CUES could be a vary of energy saving and temperature watching product designed to boost the effectivity of refrigeration systems. they're used primarily in business applications.

The downside

The main objective of business refrigeration systems is to store food product at a pre-determined temperature so as to increase product time period. In the majority cases a thermostat is incorporated within the enclosure that measures the temperature of the air within the cupboard, that successively directly switches the mechanical device on or off in a very series of cycles.

The theory is simple… by maintaining the temperature of the ‘air’ within the cupboard at a predetermined level it's anticipated that the food will strive against constant temperature. However, as a result of air features a fully completely different thermal characteristic to the majority food product it's quite traditional for the owner/operator to habitually take temperature samples of the hold on food product via a handheld probe, so in several regions this is often thought of essential therefore on guarantee food is properly preserved. So… we all know that ‘air’ temperature isn't AN correct live of ‘food’ temperature.

Air coming into a cold area has little or no thermal energy compared to the considerably larger thermal mass of most food product, and however anytime a door is opened and heat air comes into contact with the thermostat, there are often a reasonably immediate response that results in the mechanical device being energized albeit the temperature of the food has not modified.

Furthermore anytime a mechanical device starts up there square measure high energy demands on the motor windings and also the motor can ab initio work tougher to create up the suction pressure level because the cooling cycle begins, within the meanwhile but the least thermal energy that entered the enclosure can have already began to be absorbed into the considerably larger thermal mass among the enclosure which implies that in most cases, thermal equivalence is achieved by a natural entropic method instead of forced cooling by the mechanical device.

Does this mean that the mechanical device is typically running needlessly with no helpful result on the temperature of the food hold on within the cabinet? In several cases yes!

A further downside exists among the look of the mechanical device itself. 

In the majority cases one ac induction motor is employed to drive the mechanical device and additionally move the agent round the system. mechanical device motors square measure usually factory-made in a very series of normal convenient sizes, and square measure designed to deal with the worst case situation, for example; over furnished cupboard with ‘warm’ food product being another, doors left open for extended periods, unco high close temperature and variable (often low) power provide on the National Grid. 

Also, the load profile of the motor is such it needs considerably additional energy within the initial jiffy following start-up than it'll for the rest of the cycle, but the motor has no intelligent manner of adjusting the quantity of energy it attracts throughout every section of the cycle. All of this contributes to a motor and mechanical device that's outsized on purpose, uses additional energy than it must, beneath ‘normal’ in operation conditions.

Does this mean that once the mechanical device is needed to run it's drawing additional energy than is basically required to finish the task of work? In the majority cases yes!

In a shell this implies that the mechanical device is usually running once it ought to be ‘off’, and on the occasions once it's needed to run it's nearly always victimization additional energy than it must.

The answer

Enigin PLC have developed a singular combination of synergistic product that directly target these issues in a very new holistic manner. These groundbreaking solutions square measure the results of thirty years expertise in each temperature and intelligent control technology. they're currently subject to patent applications, logos and copyright style.

CUES – correct Food Temperature measuring

As a part of the CUES answer we offer a proprietary Food Mimicking Thermostat that's put in in intimate contact with the prevailing air thermostat. this implies we tend to square measure currently ready to make sure the mechanical device solely runs once there's a real would like. internet result's that the mechanical device can currently energise less typically however once it will run it'll give longer and deeper cooling cycles. generally startups are going to be reduced by between 50-70%.

The CUES Food Mimicking Thermostat contains a specially mingling food simulant wax that has constant thermal characteristics (thermal physical phenomenon and thermal mass) as typical food product. it's inherently food safe, easy to put in and allows way more correct management of food temperature.

To modify correct standardisation of the thermostat and to confirm we tend to square measure maintaining food at the proper temperature we've got additionally developed a CUES Food Block Probe. this permits non-invasive correct measuring of the hold on food among the cupboard. The CUES Food Block Probe is often positioned for good aboard alternative food product within the cupboard. a conveyable hand-held meter is then merely obstructed into the block and also the temperature are often simply scan and recorded. 

Because we tend to square measure mensuration ‘food’ instead of ‘air’, typically we tend to square measure ready to set the thermostat one or 2 degrees higher with total confidence that we tend to square measure maintaining the desired core temperature, resulting in even larger savings.

CUES – Intelligent control

Enigin PLC have extended expertise with intelligent control across several sectors, each business and industrial producing processes. but there square measure many anomalies among hermetically sealed refrigeration compressors that warrant special attention so as to maximise on the energy saving potential.

By mensuration the torsion demand on a refrigeration mechanical device motor it are often clearly seen that when the motor has overcome its initial start-up section the demand backs off considerably because the motor merely maintains the momentum throughout the rest of the cooling method. but as a result of it's no intelligent manner of matching the input power to the load demand it implies that the motor can still draw additional energy that it must.

The first law of physical science states that energy can not be created or destroyed, it will solely be regenerate to a different supply, during this case heat. this implies that the surplus current being needlessly drawn by the mechanical device motor is being regenerate to harmful ‘heat’. To any compound the matter in a very hermetically sealed mechanical device (which most are) this wasted heat is then being another to the coolant… the mechanical device then needs to run longer to beat its own unskillfulness all the whereas exasperating the matter. 

This additionally implies that once the wasted heat is finally purged from the cooling it then enters the close air round the cupboard and in a very heat climate needs to then be removed by the air-conditioning system.

The CUES intelligent control technology can perpetually monitor the performance of the motor and guarantee solely the proper quantity of energy is employed throughout every section of the duty cycle. Also, since the CUES Food Mimicking Thermostat is providing fewer however deeper cooling cycles, the addition of the CUES Intelligent Motor Controller implies that the results square measure combined with actually synergistic edges. currently the motor can pay proportionately additional of its run time in a very gently loaded state (due to the less start-ups) wherever the most effective savings square measure achieved as a result of solely the precise quantity of energy are going to be provided to try and do the task of labor – no additional – no less!

The CUES vary of Chilled Unit Energy Savers will:-

Save up to half-hour in energy prices

Provide additional correct food temperature management

The Next Generation

Enigin PLC square measure presently within the final stages of developing a spread of product ANd solutions that mix into an “Eco-system”. this is often a spread of load aspect energy saving product that square measure connected to AN Eniscope Hybrid Real Time Energy Management System, thereby providing remote web-enabled watching of individual things. this implies we are going to be ready to mechanically establish energy leaks at a granular level.

The new CUES Hybrid, because of be launched in 2013, can mix all of the advantages of the whole CUES vary into one easy product. additionally CUES Hybrid will communicate to the computer network via Eniscope in real time on vital matters like; mechanical device run time and temperature, internal food temperature, close temperature, instrumentality potency and specific running prices.

CUES Hybrid will be ready to give pre-emptive maintenance alerts well prior to a drag physically manifesting itself. this implies that homeowners, operators and engineers are often mechanically notified via email or SMS once either a mechanical device is beneath force and requiring maintenance or the temperature of hold on food being served from a show cupboard is in danger of not being adequately cooled.

All of this info are going to be archived in a very cloud-based system - 24/7/365 - and any combination of salient reports are often accessed and provided at website level to satisfy the foremost tight compliance necessities whereas at constant time providing optimum management and management of all the energy utilized in the building.
