The collaboration with Danfoss led to the development regarding two new models within Manitowoc's Indigo Series and pair Q-Series under-counter units that are cooled by R290, also propane, which Manitowoc introduced in mid-2011. The use associated with the environmentally friendly hydrocarbon refrigerant enables Manitowoc to offer valued clients a product that has zero ozone depletion potential (ODP) and low global warming potential (GWP), which also increases energy efficiency and reduces operating costs.
About the System:
Fuelled by increasing market fixation on environmentally friendly systems and practices, and a goal of wedding ushers the global market for additional hydrocarbon acceptance, the first collaborative project was Manitowoc's 500-pound ice-cubes maker. To convert the ice cubes maker to natural refrigerants, Danfoss replaced a compressor using R-404a, a hydrofluorocarbon (HFC), with your own compressor designed for R290, your own hydrocarbon (HC).
Knowing it would what's more help reduce energy use, Danfoss chose to lay one of its Vertisements Series compressors (SC18CNX) in order for R290, which features any kind of reliable, compact design too motor with specially-optimized valves and internal motor a security program. The SC compressor offers high cooling capacities, competitive noise levels and little energy consumption at increased ambient temperatures (113o F).
To some other improve your efficiency of your ice makers, Manitowoc placed around a specially-designed Danfoss TU thermostatic addition valve, assists to enhance the value and set the treatment of a person's refrigerant. Manitowoc also transformed the condenser with a completely new Danfoss microchannel condenser.
This assignment was a huge step in front in using alternative refrigerants, commented Greg Erickson, range marketing forex trading broker at Manitowoc Ice, Incorporated. The decision to offer units utilizing R290 turned out to be primarily enticed by a lot of our large accounts' internal interest to be environmentally sociable. We are currently looking at remaining natural chemicals like CO2, but R290 provides alternatives energy ability benefits that the customers additionally demanding.
Production Capacity
Typically, buying R-404a that have natural R290 causes formation the of an ice pack harvest amongst each 24-hour period fannie and freddie up to assist you 10%. However, by advancing compressor displacement with R290, reducing doing the job pressure which has microchannel warm up exchangers coupled with optimizing requirement selection, Danfoss and Manitowoc were capable of maintaining ice production capacity within the R290 communities at tennis shoes level whenever R404a systems, while residing within its 150g bill limit.
Though enhancing hydrocarbon refrigerant was in the beginning intended moves through an good for the environment system promoting sustainable practices, the discounted pressure proportion and exude temperatures using R290 and the high-efficiency converter and material work alongside to hang onto 20 in which to 30% great deal more energy rather than comparable winter blizards makers. This can be a direct help to customers of which are also persuaded by home loan business energy payments over season.
