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structure having a lower case whose top surface is arranged to be an opening through which goods are inserted and withdrawn and an upper case whose front surface is arranged to be an opening through which goods are inserted and withdrawn, the upper and lower cases each being formed by inner and outer boxes leaving a gap therebetween the heat insulating structure comprising: two pour holes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

A low-temperature show case comprising an upper case having a front opening to be covered with revolving transparent glass doors, and a lower case having upper opening to be covered with slidable transparent glass doors, said upper case being constructed in the form of oriel with its transparent side walls oriented oblique towards the front opening, and being provided with an outlet for effusing cold air to form an air curtain just behind the opening, the outlet having larger width than the front opening so as to prevent the ambient air to flow into the case.

Low-temperature show case

A refrigeration showcase comprising a display case, a machine case and an air duct connecting the display case to the machine case, the display case comprising a display table for displaying commodities as placed thereon, a cover member openably covering the display table from above to define a commodity chamber above the display table and permitting the commodity chamber to be seen therethrough from outside, and an air passage member disposed under the display table and providing a cold air supply portion for supplying cold air therethrough to the commodity chamber and a cold air discharge portion independent of the supply portion for discharging cold air from the commodity chamber therethrough, the machine case comprising a case body, a refrigerator housed in the case body and providing a refrigeration cycle and a cold air circulating blower for supplying air cooled by the evaporator in circulation, the air duct having a forward air channel for transporting the cold air, and a return air channel independent of the forward air channel.
