Air conditioning equipment must be installed on the air conditioning target so that each operation can be performed smoothly.
A parallel-type thermal storage air-conditioning system that connects the storage
Was devised. [0007] The parallel type thermal storage air conditioning equipment
The principle is as shown in FIG. That is,
The heat tank 1 and the air conditioner 2 are connected to the first path W1 and the second path W2.
Are connected in parallel with each other, and the first
The road W1 and the air conditioning target R are connected via the third route W3.
At the same time, the second path W2 on the return side of
The tuning target R is connected via the fourth route W4. And
A route at a branch point of the second route W2 from the third route W3
A switching mechanism 15 is provided. In the air conditioning mode, the path switching mechanism 15 is operated.

In the heat dissipation mode, the arrow b
Depending on the operation mode, such as wind flowing in the direction of
Because the direction of the wind flowing through the heat storage tank 1 will be opposite
is there. Therefore, as shown in the aforementioned publication,
The configuration with a single temperature sensor has the following disadvantages.
Occurs. In the heat storage mode, the conditioned air is stored in the heat storage tank 1.
Is supplied from one end 1a (the first path W1 side) of the
There is a time difference so that the conditioned air arrives with a delay toward end 1b.
It becomes cold. Therefore, the entire heat storage tank is brought into a desired heat storage state.
Only one temperature sensor to detect
In this case, it is arranged near the other end 1b on the side of the air outlet.
It is desirable. On the other hand, in the heat dissipation mode, it becomes the wind entrance
The heat is radiated from the other end 1b side and before the wind exits.
Note that there is a time lag so that the heat is delayed with the end 1a
To determine whether the entire heat storage tank has reached the desired heat release state.
If only one temperature sensor is provided,
It is desirable to arrange it near the one end 1a on the air outlet side.
No. Accordingly, the temperature sensor is suitable for the heat storage mode.
Position, accurate detection operation is expected in the heat dissipation mode.
Can't wait and set at a position suitable for heat dissipation mode

Is set to operate separately from the night control state.
ing. In the daytime control state, the first temperature sensor S1
Only the first temperature sensor S1 is used.
When the temperature is equal to or lower than the predetermined temperature (18 ° C.), the indoor unit 2
Is stopped. And, by heat dissipation
The heat of the heat tank 1 is deprived and the first predetermined temperature (18
° C), the indoor unit 2 starts cooling operation, and the first predetermined
As the difference between the temperature and the detected temperature increases, the indoor unit 2
The control device 41 functions so that the output becomes large.
You. In other words, on a very hot summer day or the like, the heat storage tank 1
Is allowed to cool and the heat storage capsule C on the outlet side exceeds the latent heat temperature
By this time, the indoor unit 2 starts cooling operation with slight output,
I will compensate for my feet. And the shortage of heat storage tank 1 is next
Secondly, that is, the detected temperature of the first temperature sensor S1
Gradually increases, the cooling output of the indoor unit 2 increases.
Control to meet the required cooling capacity as a whole
It is controlled by the device 41. Then, at night, the timer 40
