A cooling storage cabinet in which condensation is prevented from being produced under such conditions that the condensation occurs on the glazing of its doors. The cooling storage cabinet is formed of a heat insulating housing having an opening that is opened and closed by one or more slidable doors. Each of the doors is constructed of a heat insulating wall with the periphery portion of each of two opposing sides being thinner and a door sash into which each peripheral portion is fitted to slide on the cabinet adjacent the opening.

Cooling storage cabinet

A refrigerating apparatus capable of reducing the start noise of the compressor comprises a compressor 1, a condenser 2, a capillary tube 4, and an evaporator 6, serially connected by piping to form a closed loop. The apparatus further comprises a solenoid valve 3 installed between the outlet of the condenser 2 and the capillary tube 4 and a control unit C controlling the compressor 1 and the solenoid valve 3. The control unit opens and closes the solenoid valve 3 in response to the operation and stop of the compressor 1 and in particular closes the solenoid valve 3 before the compressor 1 stops.

Refrigerating apparatus

A heat insulating structure having a lower case whose top surface is arranged to be an opening through which goods are inserted and withdrawn and an upper case whose front surface is arranged to be an opening through which goods are inserted and withdrawn, the upper and lower cases each being formed by inner and outer boxes leaving a gap therebetween the heat insulating structure comprising: two pour holes formed in a wall of the upper case; a passage for establishing communication between the gaps of the upper case and the lower case; a heat insulating pipe having an end portion communicating with one of the pour holes of the upper case and extending from the one pour hole and through the gap of the upper case and having its other end portion communicating with the gap of the lower case; foam heat insulating material is injected, in the form of a foaming agent, through the other pour hole of the upper case to the gap of the upper case so as to foam and solidify; and foam heat insulating material in the form of a foaming agent is also injected through the pour hole of the upper case and through the pipe to the gap of the lower case to foam and solidify.

Heat insulating box structure and manufacturing method therefor

In manufacturing an insulating box used for a low-temperature show case having a slidable transparent windows on the top opening thereof, a recess is formed on the upper front ends of inner and outer boxes of an insulating box, said recess being provided with a frame covering the gaps between said inner and outer boxes and having a groove for receiving therein a multi-layer transparent panel. After the multi-layer transparent panel is installed in the groove and fixed with a fixation frame, an expandable insulating material is injected into the spaces between said inner and outer boxes to form said insulating box.
