As shown in figures 1 to 6, when do not need to operate rapidly freezing and only need to carry out separately running ventilation type refrigerating plant 3 time, power-on switch 6 and have power supply, storehouse temperature switch 41 starts because induction storehouse temperature is not enough, first contact 411 of storehouse temperature switch 41 is switched on, 3rd contact 423 and the 6th contact 426 of start selector switch 42 are switched on, first contact 421 of selector switch 42 and the 4th contact 424, second contact 422 and the 5th contact 425 are disconnected simultaneously, adjustment setting timer 43 is also set as ventilation type refrigerating plant 1 continuous running, first contact 431 of setting timer 43, there is power supply to make air cooling compressor solenoid winding 313 by excitatory and start air cooling compressor 31 and freeze because of connection, and the fan 323 of air cooled condenser 32 and the fan 342 of ventilation type evaporimeter 34 are activated, the 8th path 10h is opened by start with making the second freezing magnetic valve 36, because defrosting magnetic valve 35 is without the power supply be switched on, the 7th path 10g magnetic valve 35 that defrosted is blocked, and therefore refrigerant cannot flow to ventilation type evaporimeter 34 through the 7th path 10g, so refrigerant can become the gaseous coolant of HTHP after air cooling compressor 31 compresses, enter air cooled condenser 32 through the 6th path 10f again and lower the temperature into high normal pressure and temperature liquid refrigerants, then, via the input pipe 332 of the exterior bowl 331 of air cooling heat exchanger 33 and the efferent duct 334 of exterior bowl 331, 8th path 10h, second freezing magnetic valve 36, enter after the 3rd expansion valve 37 expands and become low-temp low-pressure liquid refrigerants, ventilation type evaporimeter 34 is entered again through the 9th path 10i, cold energy is provided by ventilation type evaporimeter 34 and is placed in freezing/chilled food hidden in storehouse 5 and carry out heat exchange, the refrigerant of heat exchange is via the tenth path 10j, the input pipe 335 of the inner drum 333 of air cooling heat exchanger 33 and the efferent duct 336 of inner drum 333, return in air cooling compressor 31, namely complete a ventilation type refrigerating plant 3 to operate kind of refrigeration cycle flow process.
As shown in Figure 1 and Figure 7, when pipe cooled refrigerating plant 1 carries out running refrigeration, the door in freezing/storehouse 5, Tibetan is opened, first contact 441 of microswitch is switched on, second contact 442 of microswitch is disconnected, make air cooling compressor solenoid winding 313 by excitatory and start air cooling compressor 31 and freeze, and the fan 323 of air cooled condenser 32 and the fan 342 of ventilation type evaporimeter 34 are activated, and make the second freezing magnetic valve 36 by start thus open the 8th path 10h, because defrosting magnetic valve 35 is without the power supply be switched on, the 7th path 10g magnetic valve 35 that defrosted is blocked, and therefore refrigerant cannot flow to ventilation type evaporimeter 34 through the 7th path 10g, so refrigerant can become the gaseous coolant of HTHP after air cooling compressor 31 compresses, enter air cooled condenser 32 through the 6th path 10f again and lower the temperature into high normal pressure and temperature liquid refrigerants, then, via the input pipe 332 of the exterior bowl 331 of air cooling heat exchanger 33 and the efferent duct 334 of exterior bowl 331, 8th path 10h, second freezing magnetic valve 36, enter after the 3rd expansion valve 37 expands and become low-temp low-pressure liquid refrigerants, ventilation type evaporimeter 34 is entered again through the 9th path 10i, cold energy is provided by ventilation type evaporimeter 34 and is placed in freezing/chilled food hidden in storehouse 5 and carry out heat exchange, the refrigerant of heat exchange is via the tenth path 10j, the input pipe 335 of the inner drum 333 of air cooling heat exchanger 33 and the efferent duct 336 of inner drum 333, return in air cooling compressor 31, namely complete a ventilation type refrigerating plant 3 to operate kind of refrigeration cycle flow process, meanwhile, Kai Kumen relay 45 is because there being the power supply be switched on, the contact 451 of Kai Kumen relay 45 is disconnected because energising generation is excitatory, because of unregulated power actuator cold compressor 11, therefore the first pipe cooled evaporimeter 2 and the second pipe cooled evaporimeter 2a do not provide cold energy to carry out heat exchange, so the first pipe cooled evaporimeter 2 and the second pipe cooled evaporimeter 2a can not frostings.Because just ventilation type evaporimeter 34 provides cold energy to carry out heat exchange, therefore, enter freezing/hot-air hidden in storehouse 5 only drawn by ventilation type evaporimeter 34 with the moisture of its aqueous vapor of carrying under one's arms and thing to be frozen and condense into frost.
As illustrated in figures 1 and 8, when freezing/hide the door of room to be opened and to carry out the running of ventilation type refrigerating plant 3, when closing the door of freezing/room 5, Tibetan again, first contact 441 of microswitch is disconnected, second contact 442 of microswitch is switched on thus has power supply can start timing by start-up study relay 46, suppose that the time preset is the contact 461 automatic off delay relay 46 after closing the door five minutes, then after five minutes, the contact 461 of time-delay relay 46 can disconnect automatically, ventilation type refrigerating plant 3 is shut down kind of refrigeration cycle flow process, and change and to be operated kind of refrigeration cycle flow process by pipe cooled refrigerating plant 1, when the contact 461 of time-delay relay 46 does not disconnect, the power supply that the contact 451 of Yin Kaikumen relay still has be switched on for five minutes and Kai Kumen relay 45 is still disconnected and pipe cold compressor 11 cannot be started to freeze.To be still ventilation type refrigerating plant 3 in five minutes to keep on the go kind of refrigeration cycle flow process owing to closing the door, cold energy is provided to carry out heat exchange by ventilation type evaporimeter 34, therefore, enter the hot-air in freezing/storehouse 5, Tibetan and the moisture of its aqueous vapor of carrying under one's arms with thing to be frozen, can be drawn by ventilation type evaporimeter 34 and condense into frost, and do not provide cold energy to carry out heat exchange, so the first pipe cooled evaporimeter 2 and the second pipe cooled evaporimeter 2a can not frostings due to the first pipe cooled evaporimeter 2 and the second pipe cooled evaporimeter 2a.
As shown in Fig. 1 and Fig. 9, when there being the frozen matter that can discharge moisture in freezing/room 5, Tibetan, the moisture of this frozen matter to operate refrigeration because of pipe cooled refrigerating plant 1, and makes first of this pipe cooled refrigerating plant 1 the pipe cooled evaporimeter 2 and the second pipe cooled evaporimeter 2a carry out heat exchange and frosting because providing cold energy.In order to the frost on the eliminate this pipe cooled refrigerating plant 1 first pipe cooled evaporimeter 2 and the second pipe cooled evaporimeter 2a, pipe cooled refrigerating plant 1 and ventilation type refrigerating plant 3 cross-reference can be taked, for example: setting timer 43 presets after pipe cooled refrigerating plant 1 operates five hours and namely stops, and namely change stops after being operated one hour by ventilation type refrigerating plant 3 automatically, operates so in turn.3rd contact 423 and the 6th contact 426 of start selector switch 42 are switched on, and the first contact 421 of selector switch 42 and the 4th contact 424, second contact 422 and the 5th contact 425 are disconnected simultaneously.Suppose that pipe cooled refrigerating plant 1 has operated five hours, now, first contact 431 of setting timer 43 is switched on, start air cooling compressor 31 to freeze, and the fan 323 of air cooled condenser 32 and the fan 342 of ventilation type evaporimeter 34 are activated, and the second freezing magnetic valve 36 is made to be opened the 8th path 10h by start, again, defrosting magnetic valve 35 is because of without the power supply that is switched on, and the 7th path 10g magnetic valve 35 that defrosted is blocked, and therefore refrigerant cannot flow to ventilation type evaporimeter 34 through the 7th path 10g, refrigerant becomes the gaseous coolant of HTHP after air cooling compressor 31 compresses, enter air cooled condenser 32 through the 6th path 10f again and lower the temperature into high normal pressure and temperature liquid refrigerants, then, via the input pipe 332 of the exterior bowl 331 of air cooling heat exchanger 33 and the efferent duct 334 of exterior bowl 331, 8th path 10h, second freezing magnetic valve 36, enter after the 3rd expansion valve 37 expands and become low-temp low-pressure liquid refrigerants, ventilation type evaporimeter 34 is entered again through the 9th path 10i, cold energy is provided by ventilation type evaporimeter 34 and is placed in freezing/chilled food hidden in storehouse 5 and carry out heat exchange, the refrigerant of heat exchange is via the tenth path 10j, the input pipe 335 of the inner drum 333 of air cooling heat exchanger 33 and the efferent duct 336 of inner drum 333, return in air cooling compressor 31, namely complete a ventilation type refrigerating plant 3 to operate kind of refrigeration cycle flow process.Owing to being that ventilation type evaporimeter 34 provides cold energy to carry out heat exchange; Again, because the first pipe cooled evaporimeter 2 and the second pipe cooled evaporimeter 2a do not provide cold energy to carry out heat exchange, frost on first pipe cooled evaporimeter 2 and the second pipe cooled evaporimeter 2a can gasify distillation, and absorbed by ventilation type evaporimeter 34, therefore frost on first pipe cooled evaporimeter 2 of this pipe cooled refrigerating plant 1 and the second pipe cooled evaporimeter 2a, can eliminate.
Defrost timer 47 of the present invention, can add up air cooling compressor 31 and operate the time of freezing.User can preset this defrost timer 47 after running refrigeration a period of time (a few hours) accumulated by air cooling compressor 31, starts defrosting operation.When air cooling compressor 31 is operating refrigeration, if the time that the air cooling compressor 31 that defrost timer 47 presets is accumulated the duration of runs and reached preset, defrost timer 47 can to shut down refrigeration by start air cooling compressor 31, and changes into defrosting operation.When start defrosting operation, refer to again shown in Fig. 1 and Figure 10, first contact 471 of defrost timer 47 is switched on, second contact 472 of defrost timer 47 is disconnected, 3rd contact 483 of the defrosting conversion contactor 480 that power supply is follow connected, open defrosting magnetic valve 35 and open the 7th path 10g, high pressure-temperature gaseous coolant is via the 6th path 10f, 7th path 10g, 9th path 10i and enter ventilation type evaporimeter 34, heating is carried out to ventilation type evaporimeter 34 surface and melts frosting, carry out defrosting work, and the water produced defrosting is discharged by drainpipe 35 after concentrating on water-collecting tray 34.
Suppose that the defrosting time set by defrost timer 47 is 15 minutes, so defrost timer 47 is after 15 minutes, the first contact 471 can be disconnected; Now, second contact 472 is switched on, defrosting conversion contactor 480 is not excitatory, defrosting conversion contactor first contact 481 and defrosting conversion contactor second contact 482 are disconnected, defrosting conversion contactor the 3rd contact 483 and defrosting conversion contactor the 4th contact 484 are switched on, cold energy is provided to carry out heat exchange by ventilation type evaporimeter 34, as shown in Figure 9.
Sometimes because freezing/frosting degree hidden in storehouse 5 seldom completed defrosting in 5 minutes, now, defrost timer 47 can't disconnect the first contact 471 of defrost timer 47 immediately, and just can disconnect after still keeping 10 minutes, now, the temperature of ventilation type evaporimeter 34 responded to by defrosting involution temperature switch 40, learn and complete defrosting work, first contact 401 of defrosting involution temperature switch 40 is switched on, second contact 402 of defrosting involution temperature switch 40 is disconnected, meanwhile, defrosting conversion contactor 480 is because there being power supply can be excitatory, defrosting conversion contactor the 3rd contact 483 and the 4th contact 484 are disconnected, first contact 481 and the second contact 482 are switched on, recover ventilation type refrigerating plant 3 running refrigeration, cold energy is provided to carry out heat exchange by ventilation type evaporimeter 34, as shown in figure 11.
As shown in the above description, the pipe cooled refrigerating plant 1 of the present invention and ventilation type refrigerating plant 3 can carry out running refrigeration simultaneously, compared with so carrying out separately running refrigeration with pipe cooled refrigerating plant 1 or ventilation type refrigerating plant 3, freezing/temperature of hiding in storehouse 5 can be enable to decline rapidly, thus the food in freezing/storehouse 5, Tibetan or article can be made to obtain the effect of IQF/Tibetan.Again, the present invention is when the door in freezing/storehouse 5, Tibetan is opened, because of the effect of microswitch, and make ventilation type refrigerating plant 3 replace the freezing running of pipe cooled refrigerating plant 1, therefore, enter the hot-air in freezing/storehouse 5, Tibetan and the moisture of its aqueous vapor of carrying under one's arms with thing to be frozen, can be drawn by ventilation type evaporimeter 34 and condense into frost, because the first pipe cooled evaporimeter 2 and the second pipe cooled evaporimeter 2a do not provide cold energy to carry out heat exchange, so the first pipe cooled evaporimeter 2 and the second pipe cooled evaporimeter 2a can not frostings; Again, frost due to the first pipe cooled evaporimeter 2 and the second pipe cooled evaporimeter 2a can gasify distillation, and absorbed by ventilation type evaporimeter 34, therefore the frost on the first pipe cooled evaporimeter 2 of this pipe cooled refrigerating plant 1 and the second pipe cooled evaporimeter 2a can be eliminated; Again, because the frosting of ventilation type evaporimeter 34 can melt into water in time defrosting, and discharged by drainpipe 35 after concentrating on water-collecting tray 34, therefore, can not cause freezing/to hide indoor ground moist, and chilled food also can not be caused to be mixed the situation injured by a crashing object by the white block dropped.Again, ventilation type refrigerating plant 3 of the present invention only freezes at defrosting and freezing/the hide door in storehouse 5 Shi Caiyou that is opened, other most of the times are all to be operated refrigeration by pipe cooled refrigerating plant 1, therefore, freezing/each region of hiding in storehouse can reach the refrigeration of comprehensive homogenising, and, because the first pipe cooled evaporimeter 2 and the second pipe cooled evaporimeter 2a can not frostings, therefore the present invention has the raising freeze capacity of refrigerator and effect of efficiency, ideal.
