Abstract

PURPOSE:To prevent cooling efficiency from being lowered at the engine starting time etc. by forming a cooling system as refrigerant is preferentially fed only to a cooling evaporator for a given period of time, when cooling load is high. CONSTITUTION:When a blower change-over switch 11 is turned to the high-position Hi, a relay 12 is electrified, and a circuit electrically communicated to a point of contact 12a, becomes conductive. In this mechanism, a motion timer 13 comes into action, the controller 9 of a refrigerator does not operate even if the power switch 14 of th refrigerator is turned on, a control valve 3 is kept opening, and refrigerant is fed only to a cooling evaporator 1. When the timer 13 indicates that a given period of time passed, the controller 9 of the refrigerator is allowed to operate, and refrigerant is also fed to the refrigerator. In this system, cooling efficiency is prevented from being lowered when cooling load is high.

In the figure a3, through Magnetsu 1 - Kunotsuji △ r Iz
The refrigerant gas compressed by 11130 and driven by the rotating horn of the engine M, which is
11 is liquefied and stored in the liquid receiver on -day.
It is also supplied to the evaporator 2 for the refrigerator. In this example, υIIl] valve 3 has two positions, d3 and closed, set to (j
An electromagnetic on-off valve is used, and the energized state 8 (open state) is used. A thermosensor 5 is installed on the upstream side of the thermosensor, and the opening degree of the automatic expansion tL4 is adjusted based on the temperature sensor No. 11 from the thermosensor. It is controlled so that the superheating of the refrigerant flowing into the engine is maintained at a constant level.
It is installed together with a heating device inside the air conditioning duct installed under the appliance panel. The air conditioning duct has an inlet 11 for air to be conditioned at one end and a 1:1 outlet for conditioned air at the other end. In order to avoid the inconvenience of frost formation on the cooling evaporator 1 due to overcooling of the conditioned air, the air conditioner is controlled based on the signal from the thermistor 6 for detecting the temperature of the cooling air. Device 7 interrupts the current from the power supply to magnetic clutch A, temporarily
Y compressor B (!-) is stopped. On the other hand, a constant 11 expansion valve 8 is interposed on the 1 flow side of the refrigerator evaporator 2, and the low pressure side is set at the set value, and in this case C, 0. When the temperature rises below !ikg/cj (evaporation 4 melon - 20℃), the uiJ valve is activated, and its role is to maintain a constant pressure on the low pressure side.Furthermore, the fI11 control valve 3, which opens and closes in the evening, is operated by a timer circuit. Based on the message 3 from the refrigerator control IT device 9 that has a built-in
is opened and closed. Reference numeral 10 indicates an electric switch J for the air conditioner that cuts off and on the supply of electricity to the magnetic clutch Δ, and 11 indicates a switch for switching on and off the air blower 1G attached to the air conditioning duct and for switching between strong, medium and weak air blowing. In the high (Hi) position, the relay 12 is energized, the circuit on the contact 12a side becomes conductive, and the refrigerator control device 9 is energized via the timer 13 when the refrigerator plI power switch 14 is in the closed state. This control device 9 is a cold ji! 1llii source switch 14 is
II When opening the C cutter control valve 3,
1y-A built-in circuit is forcibly turned off the magnetic clutch 8 regardless of the input direction of the mister 6. A check valve 15 is provided on the flow side of the refrigerator evaporator 2.

As mentioned above, when the force is, for example, 0.5 kgz"cd (evaporation smallpox -20°C), 1.
The temperature is maintained at the set point and the temperature is low enough to make ice. This state in which the control valve 3 is closed continues for a second set time, for example, 15 seconds. Then, when the second setting B, ``1'' has elapsed, the cooling control device 9 supplies power to the control valve 3 again and prevents it from opening.When the control valve 3 listens, the cooling evaporator 1 The refrigerant flows in again 1, and the suction side pressure of the cooling evaporator 1 n- and the IF compressor B is 2 to 3 kQ.
/Cmk Tatsuru. This pressure is much higher than the inner pressure of 0.5 kgz'c♂ of the cooling RIII evaporator 2, but due to the presence of one check valve downstream of this evaporator, the cooling evaporator 1 is The passing refrigerant gas does not flow into the refrigerator seafood container 2 and cause the internal pressure to suddenly rise.

When g/c♂ is exceeded, it automatically closes and stops the supply of refrigerant. Thereafter, the residual refrigerant in the refrigeration IF evaporator 2 continues to gradually evaporate, and is maintained at a low temperature that allows ice to be made. This state is maintained for a first set time determined by a timer built into the refrigerator control device 9, for example, 60 seconds. Thereafter, the opening and closing operations of the control valve 3 are repeated according to the first and second set times.

Since the valve is kept open, the refrigerant flows only into the cooling evaporator 1 and enters a powerful cooling operation. Just then, a signal is sent from the timer 13 to start the intermittent operation of the control valve of the refrigerator control device 90, and the refrigerant supply to Reizo Elementary School is also started. When working late, it takes about 3 minutes at 11 to use the refrigerator P1!'s cooling function, and there is little cost involved, and after about 3 minutes, you can reach a comfortable state of being in the middle room.

As a means of automatically stopping the i&pli function, a timer for the refrigerator is used only when the air conditioner's blower is in high operation. However, another implementation is possible. Then, the hot water temperature detected by the internal indoor air conditioner (=J) exceeds a certain value/: t+;'
It is also possible to use a method to set up a timer for delay activation immediately after cold tlt. However, it is also possible to automatically change the most desirable delay activation time based on the detection signal of mixed use inside the vehicle.
