[Patent Document 1] JP-A-2004-3867 [Summary of the Invention] However, in recent years, due to the improvement of the freezing capacity, the rapid freezing mode can be used to cool the cold-beam chamber storage room to a low temperature of about a pit to a thief. There is a temperature difference, and dew condensation may occur on the outer wall of (4). At this time, if the compressor is in operation so that the refrigerant having a higher temperature flows in the dew prevention pipe buried in the outer wall, the outer wall can reach, for example, 2 〇t or more. The high temperature prevents condensation from occurring. However, after the rapid freezing mode is completed, the operation is shifted to the normal cooling operation, and the compressor is stopped before the temperature reaches the 〇N temperature of the compressor, for example, _18, so that the freezing storage chamber is cooled to -3 〇 ° C as described above. -4 (When the temperature is around TC, it is necessary to report the temperature of the 〇N of the compressor at room temperature. It is necessary to report the heat leak from the inside for a long time. When the temperature of the outer wall of the case is, for example, a low temperature of less than 20 C, dew condensation will inevitably occur.

The downstream side of the dew-proofing pipe 43 is connected to a switching valve 44' for adjusting the switching flow rate or the flow path. One of the outlet sides of the switching valve 44 is connected to the freezing capillary 47 (hereinafter referred to as F capillary) and the F evaporator. 48 and a pipe of the reservoir 49; and a pipe connecting the second capillary 44 (hereinafter referred to as an R capillary) and the ruler evaporator 46 is connected to the other. The R evaporator outlet side pipe is connected to the inlet side of the F evaporator 48, and the outlet side pipe of the reservoir 49 is connected to the suction side of the compressor 41. A refrigeration defrosting sensor 51 (hereinafter referred to as an RD sensor) for detecting the pipe temperature of the ruler evaporator 46 is attached to the outlet pipe of the R evaporator 46; and the outlet 49 of the detecting F evaporator 48 is provided on the reservoir 49. The defrosting sensor 52 for freezing (hereinafter referred to as FD sensor). ~ The following 'Describes the usual cooling mode. The usual cooling mode is to alternate the cooling age and the cooling mode to cool the chambers. The mode is to switch the valve when the detected temperature of the sensor 54 rises to the temperature of the compressor 41, such as a hole. The 44 action 'reads the cold job to the R evaporator side, thereby cooling the refrigerator compartment 3 and the vegetable compartment 4. On the other hand, the F cooling mode is to operate the switching valve material so that the refrigerant flows to the F evaporator 48 side when the detected temperature of the detector (10) reaches the 〇Ν temperature of the I reducer 41, for example, to cool the cold beam. Room 6 and so on. , I03448-980320.doc 1314984 Furthermore, since the storage compartment in which the cooling is being cooled must be cooled to a minimum, even if the storage compartment that has not been cooled reaches the QN temperature, for a specific time, for example, r cold section mode 2G minutes, F cooling mode 4G minutes And does not switch the cooling mode. Specifically, in the R cooling mode, the R fan 18 is rotated to supply cold air to the refrigerating compartment 3, and the F fan 19 is stopped. In the F cooling mode, the F fan 19 is rotated to supply cold air to the cold 'East chamber 6 or the like'. For the defrosting of the R evaporator 粍, the thief fan 18 reaches the 敎 temperature at the detection temperature of the (10) sensor 51, for example, before generation Continue (four). Thus, the refrigerator compartment 3, the vegetable compartment 4, the specification switching compartment 5, the ice making compartment, and the cold compartment 6 are maintained at an appropriate temperature by sequentially switching the R cooling mode and the f cooling mode alternately. The shrinking machine 41 rotates based on the temperature difference between the set temperature of each of the set sensors and the detection temperature of the sensor or the F sensor, and the storage chamber in the cooling reaches the QFF temperature or is not cooled. The rotation is stopped if the storage chamber does not reach the temperature of (10). The fan 31 changes the rotational speed in synchronism with the number of revolutions of the compressor 41, and stops as the compressor 41 stops. The defrosting mode of the F evaporator 48 will be described below. The defrosting mode is after a specific cooling operation period in which it is considered that the cooling capacity of the F evaporator 48 is lowered due to frost formation. For example, after the operation cumulative time of the compressor 41 is 8 hours, when F is cold = type = beam Transferred by the usual cooling mode. In addition, it is necessary to cool the freezing chamber 6 and the like in order to suppress the temperature rise due to defrosting, and to increase the temperature at the end of the F cooling mode. Cooling operation. After shifting to the defrost mode, the defrost heater 20 is energized for defrost until the detected temperature of the FD sensor 52 reaches the defrost end temperature, for example, nrc, 103448-980320.doc 1314984 Defrost heater 20 is powered off And the de-defrosting force balance, etc. 'after a certain period of time, 'transfers to the normal cooling mode. mode. Subsequently, the compressor 41 is stopped after 6 minutes of the refrigeration cycle. The rapid cooling is described with reference to Fig. 1; the east mode. Rapid cooling; beam mode is rapid cooling, after the east switch 14 is operated, if the to-timing is in the normal cooling mode, it will be transferred immediately; if it is in the defrost mode or the pre-cooling operation, it will be transferred after the defrost. In the idle material mode, in order to rapidly cool the food stored in the cold heading 6 or the like, while shifting to the F cooling mode, the compressor 41 is rotated at a high speed regardless of the temperature in the storage chamber, for example, at a rotation frequency of 63 & Speed transport =. At this time, the F fan 19 and the blower fan 31 are also rotated at a high speed to increase the supply of cold air, thereby improving the heat radiation effect and performing rapid cooling. When the indoor temperature of the refrigerating compartment 3 reaches the temperature of (10) during the cooling, if the temperature of the refrigerating compartment 3 or the vegetable compartment 4 is increased by continuing the cold freezing of the shellfish compartment, the temperature is transferred to the R cooling mode to cool the refrigerated storage compartment. When the temperature of the storage chamber reaches • 〇 FF temperature, it is transferred to the F cooling mode again at the timing. Further, even if the transfer to the R cooling mode & reducer 41 is operated at a high speed, the temperature in the storage compartment is quickly brought to the 〇FF temperature, and the mode is shifted to the F cooling mode. - rapid cold; the east mode has experienced a pre-set sigh time since the time of transfer to the mode 'for example, 12 minutes or the time set by the user, or the indoor temperature of the cold beam chamber 6 has reached a predetermined value. The temperature, for example, "machine time 7" is considered to have sufficiently cooled the room quickly, and the operation is ended. Hereinafter, the dew condensation prevention mode as the t-embodiment of the present invention will be described. The condensation prevention mode is composed of the i-th specific time and the second specific time, and is transferred at tc timing after the end of the rapid freezing mode of the 103448-980320.doc 1314984, and the first specific time and the present embodiment are 20 minutes. The same control of the cooling mode. In general, even if the normal cooling mode is performed, the indoor temperature of the refrigerating compartment 3 does not reach the on temperature after the rapid freezing mode is completed, and the freezing compartment 6 is equal to or lower than the OFF temperature, and the compressor 41 is in a stopped state. Therefore, the temperature of the outer wall of the casing 2 is lower than the condensation temperature measured by an experiment or the like. Here, since the heat leakage is 20 C or less, condensation may occur, but the F cooling mode is forcibly performed at the time of the enthalpy. At this time, unlike the normal F cooling mode, the compressor 41 is rotated at a low speed, for example, at a rotational frequency of 3 Hz Hz. After the rapid freezing mode is completed, the frozen storage compartment is sufficiently cooled, so there is no need to cool it. However, if the compressor 41 is not rotated, the refrigerant having a high temperature does not flow to the dew prevention pipe 43', and the outer wall of the casing 2 cannot be heated, and is cooled by heat leakage to cause dew condensation. Therefore, it is mandatory to rotate the compressor 4 i to allow the refrigerant gas to flow to the dew prevention pipe 4 3, and the casing 2 can be heated to prevent the occurrence of entanglement. Furthermore, making it rotate at a low speed can prevent useless overcooling, saves power, and 6 is in F cooling mode. Even if it is supercooled, it is different from refrigerating to 3 or vegetable room 4, and there is no food freezing. Happening. Further, after the rapid freezing mode is completed, the first specific time is not passed, and although the compressor 4 is rotated at a low speed as described above to prevent the occurrence of dew condensation, the outer wall of the casing 2 is heated in the rapid cold type. Even if the compressor 41 is stopped, the temperature of the outer wall will be reduced to a dew condensation temperature for a certain period of time. Therefore, the first specific time is shorter than the time when the outer wall temperature of the casing 2 measured by the experiment reaches the dew condensation temperature. To prevent condensation, at the same time, by 103448-980320.doc •12· 1314984, the use of the forced low-speed rotary compressor in the two temples can prevent and use the cooling to save electricity. Do the face to prevent the C fan 31 from stopping in the condensation mode. If the rotation is synchronized with the compressor 41 in the normal state, the temperature of the refrigerant gas flowing to the dew prevention pipe 43 in the condenser 42 or the compressor casing is lowered, which is contrary to the purpose of heating. Therefore, the C fan 31 is stopped, and the refrigerant gas having a ratio of =: can be made to flow to the dew prevention pipe 43, and condensation can occur more. π is only double-prevented to prevent the dew condensation mode from being forced to shift to the F-cooling mode, and the te timing after the second specific time has elapsed, the shift to the normal it is performed, and the second specific time is based on The temperature rise of the cold storage room and the relationship between the phase and the dish degree are calculated by experiments and the like even if the compression clock is used. The r will not fall below the condensation temperature, which is set to 1. After the second specific time is left, the dew condensation prevention mode is released, and it is possible to prevent the low-speed rotation operation of the compressor 4, and the indoor temperature of the chilling room 6 cannot be cooled even if it reaches the 〇N temperature. It can be politically carried out for subsequent cooling. Hereinafter, other embodiments will be described with reference to Fig. 2 . In the present embodiment, when the indoor temperature of the refrigerating compartment 3 reaches the 〇n temperature in the "depreciation prevention mode of the -time shift", it shifts to the rule cooling mode when it is in the state. This is because even if there is no mandatory transfer to the F cooling mode, Transfer to the Ridge mode I reducer 4] Rotate and cool the cold room 3, etc. 'The higher temperature refrigerant gas flows to the dew prevention pipe to prevent condensation. At this time, 'I03448 is quickly transferred due to the cooling requirements of the refrigerating compartment 3. -980320.doc -13- 1314984 To the R cooling mode, it can also prevent the temperature of the refrigerating compartment 3 or the vegetable compartment 4 from rising. $ Further, when the indoor temperature of the refrigerating compartment 3 reaches the 〇ff temperature after shifting to the R cooling mode, In the first specific time and the second specific time, the process shifts to the condensation prevention mode. This is because if the R cooling mode is completed after the end of the R cooling mode in the first specific time and the second specific time, it is cold. The bead chamber 6 does not reach the ON temperature. Since the compressor 41 is not operated, the temperature of the outer wall of the casing (10) may fall below the dew condensation temperature.
