ある。DETAILED DESCRIPTION OF THE INVENTION The present invention is an air conditioner capable of cooling and heating operation, which reduces the noise generated from the four-way valve when the operation is stopped, and also improves the pressure balance in the refrigeration cycle. It is related to a harmonizer.

ない様になつている。 When a conventional air conditioner is shown in FIG. 1, 1 is a compressor, 2 is a four-way valve, 3 is a condenser, 4 is a pressure reducer, and 5 is an evaporator. During cooling operation, the refrigerant flows as shown by the solid line. During heating operation, the refrigerant flows as shown by the dotted line and heats the room. The electrical circuit of this air conditioner is the second
It is as shown in the figure, 6 is the contact for switching between cooling and heating, 7
is a thermostat, 8 is an extension time contact, and 9 is a blower. The extension time contact 8 is always OFF for T 1 hour (approximately 3 minutes) after the compressor 1 has stopped, and even if the ON signal is input to the compressor 1 within T 1 hour, the compressor 1 will not be turned ON. ing.

るまでに要する時間である。 In the air conditioner as described above, the extended time contact 8 does not restart the cooling operation for T 1 hour (approximately 3 minutes) after the cooling operation is stopped. This T1 hour is the time required until the pressure within the refrigeration cycle is balanced and the compressor 1 can be restarted.

きな音を発生する問題が生ずる。 In order to shorten the T1 time required for balance and to speed up the restart, energize the four-way valve 2, set the slide valve 2' in the four-way valve 2 as shown by the dotted line, and close the condenser 3.
All you have to do is connect the high pressure side and low pressure side of the. If the high-pressure side and the low-pressure side are connected by energizing the four-way valve 2 immediately after the compressor is stopped, a problem arises in that the flow of refrigerant generates loud noise inside the four-way valve.

ランスは早くなる。 The present invention speeds up the pressure balance by energizing the four-way valve T2 hours after the compressor is stopped, thereby shortening the extension time T1 for preventing restart.
The compressor stop time T 2 is, even if the four-way valve 2 is energized,
Determined based on the refrigeration cycle condition, where no particularly loud noise is generated. The energization state to the four-way valve 2 during heating operation is opposite to that during cooling operation. When the energization of the four-way valve 2 is stopped after the heating operation, the four-way valve moves and the pressure balance becomes faster.

いる。 When the electric circuit of the present invention is shown in FIG. 3, the compressor 1
After the four-way valve 2 is turned off, the four-way valve 2 is specially energized or cut off by the control contact 10.

During heating operation, the 4-way valve is ON for 2 hours after the compressor is stopped.
After that, the 4-way valve will be turned off until T 1 hour.

値を高める事が出来る。 As described above, the present invention provides an air conditioner capable of cooling and heating operations, in which the 4-way valve is turned off for T 2 hours after the compressor 1 is stopped during cooling operation, and then the 4-way valve is turned off until T 1 hour.
Turn on the 4-way valve, turn on the 4-way valve for 2 hours after stopping compressor 1 during heating operation, then turn OFF the 4-way valve for 1 hour.
It is possible to speed up the pressure balance within the refrigeration cycle without making too much refrigerant noise, and it is possible to increase product value.
