Полезная модель относится к области климатических испытаний крупногабаритных натурных конструкций авиационной, транспортной и другой техники, работающей в условиях низких температур окружающей среды, в частности техники арктического базирования. Предлагается устройство для климатических испытаний, содержащее холодильную камеру в виде надувного ангара, холодильную установку в виде низкотемпературного безмашинного азотно-воздушного хладогенератора и систему подачи хладоносителя в виде перфорированного трубопровода. Внутри холодильной камеры установлен дополнительный защитный контур в виде тента на каркасе из парусины, локализующий испытываемый объект от внутренней атмосферы камеры. Система подачи хладоносителя размещена под тентом над объектом испытаний, что обеспечивает омывание испытываемого объекта свежим хладоносителем из хладогенератора при температуре, заданной программой испытаний. Отработанный хладоноситель выходит в камеру через окна в нижней части тента на уровне пола. Техническим результатом является экономия жидкого азота, за счет подачи хладоносителя в ограниченный объем под тентом. Омывание объекта испытаний хладоносителем с заданной температурой прямо из хладогенератора обеспечивает точность воспроизведения программы испытаний. Отработанный холодный хладоноситель, поступающий из-под тента во внутреннюю полость камеры, образует защитный слой холодного воздуха между двумя контурами - стенкой ангара и тентом над объектом, компенсирующий теплопритоки от стенок ангара.

A helium management control system for controlling the helium refrigerant supply from a common manifold supplies cryogenic refrigerators with an appropriate helium supply. The system employs sensors to monitor and regulate the overall refrigerant supply to deliver an appropriate refrigerant supply to each of the cryogenic refrigerators depending on the computed aggregate cooling demand of all of the cryogenic refrigerators. An appropriate supply of helium is distributed to each cryopump by sensing excess and sparse helium and redistributing refrigerant accordingly. If the total refrigeration supply exceeds the demand, or consumption, excess refrigerant is directed to cryogenic refrigerators which can utilize the excess helium to complete a current cooling function more quickly. If the total refrigeration demand exceeds the total refrigeration supply, the refrigerant supply to some or all of the cryogenic refrigerators will be reduced accordingly so that detrimental or slowing effects are minimized based upon the current cooling function. 1.
