The objective was to evaluate the temperature performance and energy consumption of a standard Precision LCU323 three door freezer counter cabinet.
\nTemperature performance and energy consumption was tested to EN153 over a 24 hour period with the cabinet empty of product and the door closed.<\/p>\n
The tests focused on four areas;<\/strong><\/p>\n (1) Pulldown time<\/strong>: the quicker the time, the greater the energy saved (lower running costs);<\/p>\n (2) Recovery time after defrost<\/strong>: similar benefits to pulldown time;<\/p>\n (3) Maximum Discharge temperature<\/strong>: impacts on life of compressor and whole-life performance of equipment \u2013 the most critical test from Precision\u2019s perspective;<\/p>\n (4) Energy consumption<\/strong>: measured in kWh over 24 hours. The results of this test demonstrated that the Honeywell product Solstice\u00ae N40 was found to exceed the refrigeration performance of R-404A, whilst at the same time, exhibiting lower recovery time and improved pull-down time. Not to forget its lower GWP value of 1387, around a 65% reduction on R-404A<\/strong>.<\/p>\n N40 provides a non-flammable solution, with faster pull down time than R-404A.<\/p>\n
