Traditionally, condensing units use fixed speed compressors to cool refrigeration display equipment and have to be designed to handle the peak load that will be faced on the hottest days of operation. Most of the year, the cooling load is much lower because the outside temperature is not so high. This means that for most of the year, refrigeration systems containing fixed speed compressor technology are inefficient and often over-sized, wasting energy and adding substantial costs to a business.Energy Cost Savings of £400 or More Per YearIdeal for applications involving display cabinets and cold storage areas crucial to the convenience retail market sector, the Optyma™ Plus Inverter condensing units combine ease of use with maximum energy efficiency. Unlike standard fixed speed compressors that can only run at one speed and 100% power, the Optyma™ Plus INVERTER compressors are able to continuously adjust their speed (stepless 30Hz – 100Hz), up or down to reduce energy usage and precisely manage the cooling load.Cold storage energy savings of up to 25% are possible when using the latest Danfoss Optyma™ Plus INVERTER condensing units. In real terms, energy usage cost savings of up to £400 or more are achievable each and every year of operation when comparing a Danfoss Optyma™ Plus INVERTER condensing unit with a fixed speed alternative. In addition, less product wastage occurs because chilled products are maintained far more closely to their optimum storage temperature and humidity levels.Compared to standard fixed speed compressor technology, Danfoss inverter compressors used in the Danfoss Optyma™ Plus INVERTER condensing units also have greatly reduced start/stop and short cycling functions as they precisely match the required load from the system. As a result, they experience far less stress on the compressor motor, leading to increased reliability, longer system life, less breakdowns and reduced costs associated with engineer’s call out charges.
