Hereafter, the operation of A central control freezer system having remote separated refrigerators constructed as above according to the present invention will be described.

Referring to Fig. 1, The central freezer 2 including a compressor, a condenser and an evaporator is installed on the compartment of the central freezer system 1 for compressing and circulating the refrigerant, thus the chill air is generated, and it is charged inside of the chill air tank 3.

After the chill air is charged inside of the chill air tank 3 with the

operation of the central freezer 2, the chill air is transferred with the operation of the chill air fan 6 from the chill air tank 3 to the remote separated refrigerators 14 through the main chill air hose 6 and the branch chill air hoses 7, and then the temperature inside of the refrigerators 14 can be lowered for a predetermined temperature set with the temperature controller units 12 by exchanging heat with the chill air supplied from the chill air tank 3.

Whereas the chill air can be suitably supplied to the remote separated refrigerators 14 with the operation of the chill air cutoff valve 26 and the chill air fan 4.

As shown in FIG. 2 shows a sectional perspective view of a temperature controller according to the present invention, the chill air, which is generated by the central freezer 2, is transferred to the plurality of refrigerators 14 by the main chill air fan 4 installed on the central chill air tank 3 through the main chill air hose 6 and the branch chill air hoses 7, Thus the temperature inside of the respective refrigerators 14 can be independently automatically lowered for a predetermined temperature set with the temperature controller units 12 inside of the remote separated refrigerators 14 since the chill air can be controlled with the flow quantity of the chill air, which is passed through the chill air valve 13 of the

automatic temperature controller units 12 inside of refrigerators 14, whereas the chill air valve 13 is operated with a solenoid device on the direction of the automatic temperature controller units 12, and the pressure check valve 16 is operated with a solenoid device on the direction of the automatic temperature controller units 12.

After the temperature is raised by exchanging a heat with the stuff inside of the remote separated refrigerators 14, the chill air valve 13 is automatically opened for a predetermined temperature set with the temperature controller units 12, simultaneously the warm air is discharged out through the pressure check valve 16 installed on the outlet of the refrigerators 14 since it is opened with a raised pressure due to an increased volume of the chill air entered inside of the refrigerators 14 or it is opened with an order of the temperature controller units 12 inside of the refrigerators 14, thus the warmed air is discharged out of the refrigerators 14 through the pressure check valve 16, and then the warmed air is retrieved for preventing to waste a cooling energy in central control freezer system 1, thus the warmed air is returned to the central chill air tank 3 by the retrieve fan 22 through the branch retrieve hoses 17 and the main circulation hose 18, so that the temperature of the warmed air is lowered for a predetermined temperature again in the chill air tank 3

of the central freezer system 1, thus the temperature inside of refrigerators 14 is quietly lowered continuously again for a predetermined temperature set with the temperature control unit 12.

Further the chill air cut off valves 26 are installed on the main chill air hose 6 for interrupting to supply the chill air, so that it can be for preventing to waste a cooling energy in the central freezer system 1 when one of the remote separated refrigerators 14 is not operated or in a pause, and the branch chill air connectors 8 are installed on the remote separated refrigerators 14 connecting/disconnecting with the branch chill air hoses 7 respectively; and the retrieve connector 30 installed on the remote separated refrigerators 14 connecting/disconnecting with the branch retrieve hoses 17 each other for installing easily the remote separated refrigerator 14 on the central freezer system 1 ; The temperature controller units 12 including the temperature sensor 11 and the chill air valve 13 installed on the inlet of remote separated refrigerators 14 respectively, and the pressure check valves 16 installed on the outlet of remote separated refrigerators 14 respectively, and the pressure check valves 16 connected with the temperature controller units 12 through the electric line 10 respectively, thus the chill air valve 13 the pressure check valves 16 are automatically controlled for a predetermined

temperature set with the temperature controller units 12; When the temperature of the chill air is raised after exchanging heat with stuff inside of the remote separated refrigerator 14, the temperature of the air is sensed with the temperature sensor 11 in the temperature controller units 12, accordingly the chill air valve 13 and the pressure check valve 16 can be opened in a procedure for a predetermined temperature set with the temperature controller units 12, thus the chill air is automatically supplied for lowering the temperature inside of the remote separated refrigerator 14 from the chill air tank 3 through the chill air valve 13, also the warmed air is discharged out of the remote separated refrigerators 14 since the pressure check valve 16 is opened with a increased pressure, whereas a pressure is raised inside of the remote separated refrigerator 14 since the volume of the chill air increased inside of the remote separated refrigerator 14 having an insulated solid wall, further another procedure of the operation, the pressure valve 16 can be operated in a procedure with a solenoid device for controlling a predetermined temperature set with the memory of the temperature controller units 12 since the pressure valve 16 is connected with the temperature controller units 12 through the electric line 10, thus the temperature of the chill air is controlled for a predetermined temperature set with the temperature controller units 12 in

a procedure as an automatic feedback system.

When the temperature is over lowered inside of the remote separated refrigerator 14 for a predetermined temperature set with the memory of the temperature controller units 12, the chill air valve 13 is closed for interrupting to supply the chill air to the remote separated refrigerator 14, thus the chill air is not discharged out of the remote separated refrigerator 14 any more, since the pressure check valve 16 is closed with a spring force or with an order of the temperature controller units 12 in a procedure as an automatic feedback system, thus the chill air is not entered inside of the remote separated refrigerator 14, so that a temperature is constantly maintained for a predetermined temperature set with the temperature controller units 12, in a procedure as an automatic feedback system, inside of the remote separated refrigerators 14.

According to this present invention, the cooling temperature can be controlled easily inside of the remote separated refrigerators 14 since it can be controlled with the flow quantity of the chill air and the freezing power of the central freezer 2.
