Don't really know that this is the right forum for this inquiry, but:
Looking to source a low capacity air cooled refrigeration package that would end in a split duct, or potentially (2) ducts; to deliver and return at least 950 M^3/hr of air; that would make at lowest minus 38 C Air Temp;based on 40-deg C ambient; would turn down on the compressor to about 15%; have a peak capacity of 1.8 KW at the described temperatures.
This a singular refrigeration unit to mate to a variety of active freezer "test modules" such that fan within the module will be speed controlled and internal geometry modified to imitate freezing of a variety of products in packages or tray packs....Largest package only about 4-Kg. nominal freezing times in the 4-12 hour range.
Package would subsequently be modified to effect mating to the variety of modules mentioned, facilitate transport and reconnection, potentially do some data acquisition and so on. Warranty would be expired the day after it was plugged in...High side issues only involve turndown; COP and SEER part load performance etc. not of consequence. Low side arrangement could obviously be custom built but though I would find out if somebody is close already. Defrost unimportant...
Near conventional refrigerants and lubricants....I don't believe an autocascade would be a real good solution because when this thing require service or input it may have to be done at fairly remote locations.
Modules would all be constructed by the OEM-Customer. Lots of transducers and similar on each module.
