Abstract: A cryogenic freezer with cryogenic vapor control is disclosed. The cryogenic freezer is characterized in that the vapor control system is adapted to control the speed of the transition fan which moves some of the cryogen from a first cryogenic freezer to a second freezer in response to differences between the temperature of the process room, operating temperature of the cryogenic freezer; and a temperature of the exhaust. By adjusting the transition fan speed in response to such temperature differences the vapor control system operates to limit the flow of air from the process room into the freezer and also limits cryogen vapor flow from the freezer to the process room.

Abstract: When the start button is pushed after the door of the supply chamber is closed, carbon dioxide gas is ejected from the nozzle placed at the upper part of the horn. The carbon dioxide gas is converted to powdered dry ice by adiabatic expansion in the horn, and the dry ice falls on fresh food or other items to be cooled in a box or plastic bag placed under the horn. In order to obtain a desired amount of dry ice constantly, the ambient temperature, the pressure of the carbon dioxide gas, the interval time since the last ejection are counted in determining the carbon dioxide ejecting time length.

Abstract: A self-contained cooler/freezer apparatus for carrying items in a frozen or refrigerated environment. The apparatus comprises an insulated container which is divided into two portions. The first portion is utilized for item storage and the second portion houses a pressurized coolant compartment for storing a solid coolant; namely, solid carbon dioxide or dry ice. The pressurized coolant compartment comprises removable insulation panel. These insulations panels are utilized to control the rate of heat transfer from the first portion to the dry ice within the pressurized coolant compartment. Based upon number of factors including desired temperature, storage duration, total item weight, the quantity of dry ice and the number of removable insulation panels can be determined. In essence, the pressurized coolant compartment is a controllable heat sink. Within a short period of time, the dry ice starts to sublimate, thereby forming cold gaseous carbon dioxide at a high pressure.

Thermal sensor means sense the temperature in the second chamber and control a liquid CO.sub.2 flow control valve in the liquid CO.sub.2 supply system.

Abstract: Refrigeration is produced by passing liquid carbon dioxide through a narrow slot into an enclosure or conduit having an inlet and an outlet in communication with ambient atmosphere. Liquid carbon dioxide is converted to solid and gaseous phases upon passage through the slot to produce a refrigeration effect and such phases are directed toward the enclosure exit thereby entraining ambient atmosphere in the solid and gaseous stream. This entrainment and mixing is effective to cause a relatively rapid sublimation of the solid carbon dioxide after exiting the enclosure and thus permits uniform refrigeration of a chamber into which the solid and gaseous carbon dioxide is discharged.

Abstract: A cabinet cooler or freezer which efficiently utilizes cryogenic refrigeration either with or without mechanical refrigeration. The freezer intermittently freezes relatively large batches of food by efficiently utilizing the natural expansion effect of a liquid cryogen, in combination with mechanical circulation by blowers, to create an overall circulation that efficiently removes heat from the food. A secondary circulation effect is induced, in a manner similar to the operation of a jet pump, which amplifies the circulation and allows CO.sub.2 to be employed with modulating valve control to achieve uniformly low temperature throughout the cabinet without snow build-up on the cabinet bottom. Some cabinet versions create a cyclonic circulation pattern about a vertical axis that is particularly effective.

Abstract: A holding chamber may be supplied from a storage vessel system with a cryogen, such as liquid CO.sub.2, or it may itself be large enough to take the place of a separate storage vessel. The temperature within the holding chamber is reduced to the triple point or below to form a refrigeration reservoir of solid cryogen, as by removing vapor from the chamber to cause evaporation or by employing mechanical refrigeration. The stored cooling power of the reservoir is later employed to meet a large or a periodic refrigeration demand and is thereafter replenished over a number of hours, preferably during a period of non-peak electric demand. This storage principle can be incorporated into a variety of different refrigeration systems. For example, a CO.sub.2 storage system may be used to produce and store solid CO.sub.2 during a period of low demand upon a coupled mechanical refrigeration system; thereafter, the solid CO.sub.
