Below pass through the specific embodiment, and the utility model is described in further detail in conjunction with the accompanying drawings.
The specific embodiment
Referring to Fig. 1, in the present embodiment, in the refrigeration system that constitutes by compressor 1, condenser 2, major loop capillary 4, refrigerator evaporator 6 and freezer evaporator 7, between the port of export and major loop capillary 4 of condenser 2, bypass magnetic valve 3 is set, connect the arrival end of freezer evaporator 7 at the bypass port of export of bypass magnetic valve 3 by bypass capillary 5, adopt mechanical temperature controller 9;
Referring to Fig. 2, temperature controller 9 is set in the present embodiment is double-contact temperature control change-over switch, wherein, the switch contact a of temperature controller 9 is serially connected in the electric power loop of electromagnetic valve coil 10, and the switch contact b of temperature controller 9 is serially connected in the electric power loop of compressor 1; It is in parallel with switch contact b in the temperature controller 9 that quick-frozen switch 8 is set.
In the present embodiment, the control method of mechanical temperature-control direct cooling refrigerator refrigeration system is system works to be set under following dual mode:
First kind: quick-frozen switch 8 is connected, and the electric power loop of compressor 1 remains on on-state, by the on-off of temperature controller 9 control electromagnetic valve coils 10; Reach when stopping cryogenic temperature at temperature of refrigerating chamber, temperature controller 9 is connected the electric power loop of electromagnetic valve coils 10, and magnetic valve 3 switches cold-producing mediums and directly enters freezer evaporator 7 by bypass capillary 5; When refrigerating chamber reached the temperature that needs refrigeration, temperature controller 9 disconnected the electric power loop of electromagnetic valve coil 10, and magnetic valve 3 switches cold-producing medium and enters the refrigerator evaporator 6 and the freezer evaporator 7 of series connection by major loop capillary 4;
Second kind: quick-frozen switch 8 disconnects, and the electric power loop of compressor 1 is by the switch contact b control on-off of temperature controller 9; Reach when stopping cryogenic temperature at temperature of refrigerating chamber, the working power that the switch contact b of temperature controller 9 cuts off compressor 1 stops refrigeration; When refrigerating chamber reaches the temperature that needs refrigeration, the switch contact b of temperature controller 9 connects the working power of compressor 1, disconnect the electric power loop of electromagnetic valve coil 10 simultaneously, cold-producing medium enters the refrigerator evaporator 6 and the freezer evaporator 7 of series connection by major loop capillary 4.
In second kind of working method: when reaching at temperature of refrigerating chamber when stopping cryogenic temperature, the working power that the switch contact b of temperature controller 9 cuts off compressor 1 stops refrigeration, but connected the electric power loop of electromagnetic valve coil 10 simultaneously, at this moment, though do not freeze, electromagnetic valve coil 10 still is in the state of connecting power consumption; For this reason, can be by as shown in Figure 3, quick-frozen switch 8 is set throws off the pass for double-pole is two, wherein, the switch contact c of quick-frozen switch 8 is switch contact b parallel connections of temperature controller 9, and the switch contact d of quick-frozen switch 8 is serially connected in the electric power loop of electromagnetic valve coil 10, when quick-frozen switch 8 disconnects, no matter temperature controller 9 is in any state, keep solenoid 10 for outage, reduce energy consumption with this.
