An object is to provide a method of manufacturing a low-temperature storage in which an insulating performance of an insulating box article is enhanced, and an amount of contents of an inner box can be enlarged. In the low-temperature storage comprising: the insulating box article constituted by placing a foamed insulating material between an outer box and the inner box; and a vacuum insulating panel disposed on the surface of the outer box on the side of the foamed insulating material, a thickness dimension of the foamed insulating material between the inner box and the vacuum insulating panel is set so that a temperature of the surface of the vacuum insulating panel on the side of the inner box is not less than a predetermined temperature.

Method of manufacturing low-temperature storage, and low-temperature storage

The invention has an object to provide a door unit for a cold storage, enabling easy opening and closing operations of a door by engaging a latch with a latch receiver. The door unit includes a handle pivotally mounted on the side face of an outer door on its non-pivotal side at a predetermined height, and a latch receiver provided on the forward portion of a side surface of a main body at a height corresponding to the handle. The handle includes a grip to be grasped by fingers of a hand, and a latch detachably engageable with the latch receiver so that the latch engages a roller of the latch receiver in a state of the substantially vertical grip, and when the grip is pivotally moved in a direction away from the main body to a position where the grip intersects a horizontal plane at a predetermined angle, the pivotal movement of the handle is stopped and the latch disengages from the roller of the latch receiver.

Door unit for cold storage

An entry of air from the outside of an incubator into an incubation room is prevented. The incubator comprises an adiabatic box main body having an opening on a front face thereof, an adiabatic door mounted to the adiabatic box main body to be opened/closed, a transparent inner door which closes the opening to be opened, and a storeroom surrounded with the inner door and the adiabatic box main body to incubate samples such as cells or microbes. The adiabatic box main body comprises a metal outer box, a metal inner box, a heat insulating material arranged in the outer box between the outer box and the inner box, and an air layer arranged more inside than the heat insulating material. Pressure of the storeroom is set higher than that of an outside space of the incubator.

Incubator

A low-temperature storage cooled/maintained in an ultra low temperature range, in which door lowering is automatically modified by an opening/closing operation of a thermal insulating door, and a concave/convex portion which is a contact portion with respect to a door switch disposed on the door can be secured. The low-temperature storage includes a thermal insulation box main body having an opening in a front surface thereof; a thermal insulating door openably/closably attached to the thermal insulation box main body by a plurality of hinges to close the opening; and a cooling device which cools a storage chamber formed by the door and the main body, wherein a spacer having a guide surface to forcibly correct door lowering by a closing operation of the thermal insulating door is disposed on a side on which any hinge is not disposed.

Low-temperature storage

An object is to provide a low-temperature storage capable of further dividing a medium storage chamber divided by a medium partition into upper/lower small sections (small storage chambers) by adding of an optional component and changing of an inner door, and the storage comprising; a thermal insulation box main body having an opening in a front surface thereof; a thermal insulating door openably/closably attached to the thermal insulation box main body; a medium partition which divides the opening into upper/lower medium openings; a shelf which divides a storage chamber formed by the thermal insulating door and the main body into upper/lower chambers in a position of the medium partition; a cooling device which cools the storage chamber; a metallic optional partition member which further divides the medium openings into upper/lower openings; a frame member formed of a resin and attached to a front part of the partition member to support an optional gasket; and a plurality of inner doors which openably close small openings divided by the partition member.

There is disclosed a cold storage which improves a door insulating performance, and which is preferable particularly for low-temperature insulation of chemicals, and the like. A low-temperature insulating showcase is formed by openably closing a storage chamber opening constituted in an insulation box by a door, the door is constituted of a transparent panel and a see-through composite layer glass, and a panel is detachably attached to the storage chamber side of the composite layer glass.

Cold storage

A refrigerating apparatus improves the insulating effect of a refrigerating chamber which is maintained at ultra low temperatures by a twin refrigerating apparatus. A vertical ultra low-temperature freezer,is composed of an insulating frame with a composite structure of a vacuum insulating panel and a foam insulating material, an insulating door with a composite structure of vacuum insulating panels and a foam insulating material, and a twin refrigerating apparatus which cools goods stored in the insulating frame. Ultra low temperatures are produced by the twin refrigerating apparatus in which a high-temperature side refrigerant circuit and a low-temperature side refrigerant circuit are in cascade connection.

Refrigerating apparatus

Low temperature storage cabinet

A temperature controlling pseudo load container for an insulated cold cabinet is provided in which the pseudo load container contains water or physiological saline and comprises at least one sealable opening portion for pouring water or physiological saline into the container and sensor arranging portions in which a temperature controlling sensor, and preferably a temperature recording sensor in addition, can be mounted closely to an external wall of the container and kept out of direct touch with the cold air in the insulated cold cabinet.

Temperature controlling pseudo load container for insulated cold cabinet

A heat insulating structure comprising a vacuum insulator fixed to a surface on which the vacuum insulator is to be applied is provided for the purpose of improving the workability in fixing the vacuum insulator to the surface to be applied. A thermally adherable layer comprising a thermally adherable material is made between the vacuum insulator and the surface to be applied, and the thermally adherable layer is heated and melted whereby the vacuum insulator is fixed to the surface to be applied.
