FIELD: the invention refers to testing materials namely to testing ground on frost-resistance.
SUBSTANCE: the aim of the invention is in improving manufacturability in the process of tests at application of a compact autonomous refrigerating equipment located in room type premises. For achievement of this aim inside the arrangement in its lid a cavity having a gag with thermal protection is fulfilled and there are posts fixing the position of the lid in relation to the horizon of water and a grate fixed to the lid.
EFFECT: improves manufacturability of a compact refrigerating equipment.
