(Prior Art) Conventionally, this type of refrigeration Machine “C1 analogy (J real 111
As disclosed in Japanese Patent No. 1, 1983-65233, a refrigerant F1 force detection means for detecting the refrigerant pressure in the refrigerant circulation system is provided, and the rotation speed of the blower fan of the condenser is set to a low speed.
When the high pressure in the refrigerant circulation system exceeds the set value for compressor protection, the rotation of the condenser blower fan is switched from the low speed side to the high speed side and the condenser coolant 0.
Increasing the capacity - by increasing the high pressure pressure setting value or higher than 10V? There is a known system in which the FE compressor can be operated continuously without operating the high-pressure switch by suppressing the

圧圧力を設定値に保持制御するのが望ましい。(Problems to be solved by the invention) However, in the conventional method described in 1.
When the rise is suppressed, the high pressure may drop too much below the set value as the condenser blower fan shifts to high-speed rotation. It is desirable to maintain control at a set value.

A control means is installed to control the rotation speed steplessly (no, variable control of the cooling capacity of the condenser is required)
It is conceivable to converge and maintain the value approximately at the set value.

圧力開閉器が作動し、圧縮機の停止を招くことになる。However, the second idea is that in order to maintain and control the refrigerator's steady operating state at a high pressure with a small hunting width, the bending speed of the blower fan must be set at a constant speed of 3
It is necessary to set the time constant (A) large (4T) so that the high pressure and low force can be maintained in a normal operating state. Starting 11 ill has various drawbacks 3.1 IJ-wat3
．． During the start-up of refrigeration, the high pressure tends to drop significantly, but the condenser blower fan nevertheless remains stopped until the high pressure reaches the set value, after which the high pressure reaches the set value. When it exceeds the time constant, gradually increase the rotation speed and start operating!
The increase in the cold combustibility of the condenser was effective against the sudden rise in high pressure.As a result, the high pressure increased abnormally, causing the high pressure switch to operate and causing the compressor to stop. Become.

る。In addition, since the above-mentioned Ql (high pressure abnormality -1: even if the pressure does not rise) is quite large, the hunting width in the process of converging to the set value is large, and The convergence time becomes longer, the evaporator is more likely to be frosted, and the load on the compressor is increased.

By starting the convergence control of the high pressure to the set value only after the high pressure has been set, a sudden rise in the high pressure can be effectively suppressed and the operation of the high pressure switch C can be prevented. To successfully converge a high pressure to a set value in a short convergence time with less hunting.

)'s outdoor blower fan <2a) immediately soft-starts, then continues to rotate at high speed at its maximum rotation speed for a predetermined time (1>
As a result, the high pressure (P) is effectively suppressed from rapidly increasing while the outdoor blower fan (2a
) is approximately stabilized at a predetermined value (Po) that is less than the set value (pset) corresponding to the high speed rotation of the motor. Therefore, the high pressure (P) increases while responding well to the rotation speed control of the outdoor fan (2a), and as a result,
The high pressure (P) has a good transition towards the set value (p5et) and has a short convergence time
) will converge smoothly. J, the high pressure switch does not operate due to the sudden increase in high pressure (P) at startup as in the past, and the compressor (1) can be operated continuously, and the high pressure (P) ) to the set value (Pset), frost formation on the indoor heat exchanger (4) (evaporator) and increase in load on the compressor (1) can be effectively suppressed.
