Calculator for refrigeration racks
FIND OUT WHETHER to invest in new tech- nologies by using the new calculation tool from Advansor which provides pay-back time and energy savings.
Advansor has developed the calculation tool for organisations investing in a refrigera- tion rack. The calculation is based on the spe- cific rack, the technology and surrounding climate.
Advansor technical director, Kenneth Bank Madsen, said it is great to have technol- ogy with plenty of functions and features, but they don’t always provide higher efficiency or reduce energy consumption.
“If that is the case we do not recommend it to our customers – we want to make sure they get value for money,” he said.
For beginners Advansor recommends at least investing in permanent magnet motors. “This is usually always a highly efficient so- lution that reduces the pay-back time for re-
frigeration racks above 30 kW,” he said.

“Depending on the compressors and the rack, it might also be worth adding new cylinder unloading technology to a rack specification.
“By using the new cylinder unloading tech- nology a better capacity regulation with less compressors is achieved and thereby the en- ergy efficiency is improved.”
This technology can be applied to all racks from 30 kW and up using Bitzer compressors and is used by European retail chain COOP.
Another new option to add is the Ultra- Low Superheat Module, which can replace the complex pump systems.
It allows a very low returning temperature from the evaporators and collects any re- turning liquid.
It is suited to warm climates and is even more efficient when combined with a gas ejector.
The ULS Module can be attached to just about any Advansor rack from around 100 kW and up and is being used by medium sized supermarkets and big warehouses.

Ultrasonic energy meter
THE SERIES UBT clamp-on ultrasonic thermal energy meter is an economical clamp-on ultra- sonic heat meter.
It is an ultrasonic alternative to the traditional inline thermal energy meters. The series uses temperature sensors for energy measurement and ultrasonic waves with time differentials for flow measurement.
It can be used in building services, energy management and chilled water circuits.
Dwyer Instruments has also released the Se- ries UFM2 compact ultrasonic flowmeter.
These economical, clamp-on, ultrasonic flow- meters use the transit-time difference to meas- ure flow rates in pipes and can measure velocity and flow in pipes with outside diameters ranging from 3/4 to 7" (25 to 180 mm).
This model comes with a volume pulse and 4-20 mA flow rate output to provide non invasive pipe measurement.
