摘要： A cooling storage cabinet includes a freezing compartment, a refrigerating compartment, a compressor, a three-way valve, and a control circuit. The control circuit is configured such that: when an internal temperature of the freezing compartment becomes lower than a lower limit temperature during R-compartment F-compartment alternate cooling, starting R-individual overcool preventing control is requested, the rotational speed of the compressor is decreased by one stage and, subsequently, the three-way valve enters “R-side open state”, and individual cooling of the refrigerating compartment is executed; thereafter, every 30 seconds, the rotational speed of the compressor is decreased by one stage; when the refrigerating compartment temperature becomes lower than a lower limit temperature, stopping R-individual overcool preventing control is requested; and then, the process shifts to individual cooling of the freezing compartment, and after the freezing compartment again becomes lower than the lower limit temperature, the compressor is stopped.

摘要： A flow-down-type ice making machine in which ice cubes reliably separate and drop from the lower end of an ice making plate, an ice guiding member can be placed close to the ice making plate, and the amount of ice storage is increased. An ice making section (10) is made up of a pair of ice making plates (12, 12) placed opposed to each other in a substantially vertical position and of evaporation tube (14) provided meandering between the ice making plates (12, 12). The ice guiding member (32) attached to an ice making water tank (22) is placed right under and close to the ice making section (10). The ice guiding member (32) is formed in a reverse V-shaped cross-section and is placed so that the top of the ice guiding member is located in the middle between the back sides of the ice making plates (12, 12). A slope (32a) tilting from the top of the ice guiding member (32) to one side of the top faces below one ice making plate (12), and a slope (32a) tilting from the top of the ice guiding member (32) to the other side of the top faces below the other ice making plate (12). An outwardly projecting lower end projection (20) is formed on each ice making plate (12), at the lower end of its surface facing each ice making region (12) of the ice making plate (12). Because of the presence of the lower end projection (20), an ice cube (M) running onto the lower end projection (20) is separated from an ice making surface.

摘要： In a refrigeration unit including a variable performance compressor driven by an inverter motor, a sensor is configured to detect a physical amount corresponding to a refrigerant pressure on the high-pressure side of a refrigerant circuit. A measured value of the physical amount is compared with a first reference value corresponding to a first predetermined pressure of the refrigerant and a second reference value corresponding to a second predetermined pressure lower than the first predetermined pressure. A protective operation can start if the comparison result indicates that an actual refrigerant pressure is higher than the first predetermined pressure. The performance of the compressor can be gradually lowered if the comparison result indicates that an actual refrigerant pressure is between the first predetermined pressure and the second predetermined pressure.

摘要： A cooling device is provided with an inverter compressor. Set speeds of the inverter compressor can be switched to six stages from a first speed to a sixth speed. The relationship between each of the set speeds of the rotational speed is set so that the stages adjacent to each other have gradually larger differences in rotational speed as the rotational speed becomes higher. With this, independently from the level of the rotational speed, a degree of increase in cooling performance between each of the stages can be equalized. In a case of performing a control to increase or decrease the rotational speed of the inverter compressor stage by stage depending whether an actual temperature drop rate is larger or smaller than a target temperature drop rate, the change amounts in cooling performance that can be substantially equalized, and too high or too low cooling performance does not result, i.e. fluctuation in cooling performance can be minimized. Thus, control to drop the internal temperature in accordance with a predetermined cooling characteristic can be stably performed.

摘要： Disclosed is an abnormality detecting method for an automatic ice making machine that can quickly detect an abnormality to delay an ice-making time or an abnormality to shorten the ice-making time, if occurred. A down flow type ice making machine includes two ice making units, one control means, and an ice storage room. Each ice making unit has an ice making part, an ice-making water tank that stores ice-making water, a circulation pump that feeds the ice-making water stored in the ice-making water tank to the ice making part, and a float switch that detects the amount of the ice-making water in the ice-making water tank. Upon elapse of a preset first abnormality occurring time from a time of first detection of an ice-making complete water level by the float switch in any one of the ice making units, when the float switch in any one of the other ice making units has not detected the ice-making complete water level, the control means decides that an abnormality has occurred in the ice making unit.

摘要： The peel off between an ice making plate and an insulating layer or between the insulating layer and heating means is prevented so that an ice making operation can be performed efficiently. Also, a metal plate is insulated from the heating means reliably.An evaporation pipe 14 and electric heaters H1 to HN are provided in an ice making member 11. A coolant is circulatingly supplied through the evaporation pipe 14 so as to cool the ice making member 11 and ice making water is supplied to the ice making member 11 so as to form an ice block M during the ice making operation. During the deicing operation, heat is generated in the heaters H1 to HN by applying current so that the ice block M is removed from the ice making member 11 by melting. The ice making member 11, in a state that an insulating layer 12b lies between a metal plate 12a to which the evaporation pipe 14 is fixed and the heaters H1 to HN, is formed by bonding the metal plate 12a with the insulating layer 12b, and the insulating layer 12b with each of the heaters H1 to HN by thermocompression. Also, in addition to thermocompression bonding, the external outline of the heating means (H1 to HN) may be located inside the insulating layer 12b.
