The Refrigeration Van of Low Temperature Supporting type intercepting Inflow and Incoming of Inner Air and Outer Air of Container of Spouting Air to open the Door

摘要

The present invention is a low temperature refrigeration tower vehicle equipped with a container made of a refrigerator and a heat insulating outer wall, and a barrier forming device by air discharge consisting of a motor, an impeller, an air direction panel, a limit switch, and a case. The cold air inside the container is prevented from leaking out, and the blocking film forming apparatus by the air discharge that prevents the inflow of outside air can be maintained to maintain the freezing temperature inside the container at an appropriate level. The quality of frozen products such as sensitive ice creams and frozen meats does not change, and they can be transported to the destination, and the freezing performance is improved by preventing the frost on the evaporator part of the freezer due to the internal and external temperature difference generated when the door is opened. Outflow of inside and outside air by the discharged air when opening the door of the structure Is designed for low temperature refrigeration retained tapcha to block the influx.
