Embodiments of the present invention will be described below with reference to the drawings.

(First Embodiment) FIG. 1 is a view showing a configuration of a room air conditioning system of a hotel or the like as a first embodiment of the present invention, wherein 1 is a heat exchange fluid (hot or cold water) producing apparatus. The heat exchange fluid produced by the heat exchange fluid production device 1 is pressurized by the pump 2, passes through the main pipe 3,
The water is divided by branch pipes 4 and supplied to guest rooms 5 to 7. And
The fluid that has undergone heat exchange in the guest rooms 5 to 7 joins the main pipe 9 through the branch pipe 8 and circulates back to the heat exchange fluid producing apparatus 1 again.

Next, in FIG. 2, a heat exchange unit 1 for exchanging heat with the heat exchange fluid sent from the branch pipe 4 is provided in the passenger compartment 5.
0 is provided. The heat exchange unit 10 includes a heat exchange unit 11 for cold water and a heat exchange unit 12 for hot water, and when the heat exchange fluid passing through the branch pipe 3 is cold water, the heat exchange unit 11 for cold water is When the heat exchange fluid passing through the branch pipe 4 is hot water or a fluid having a temperature slightly lower than the hot water, the heat exchange fluid is configured to pass through the heat exchange unit 12 for hot water. Then, the flow rate of the heat exchange fluid that has passed through the heat exchange unit 10 is controlled by the adjustment valve 13, merges with the main pipe 9 via the branch pipe 8, and then returns to the heat exchange fluid manufacturing device 1.

Reference numeral 14 denotes a fan coil motor. The fan coil motor 14 is configured to suck air from the passenger compartment 5 and return the air to the passenger compartment 5 again through the heat exchange unit 10. Reference numeral 15 denotes a fan coil that controls the fan coil motor 14.

Reference numeral 16 denotes a controller. The controller 16 includes a pipe temperature of the branch pipe 3 due to the heat exchange fluid flowing through the branch pipe 3 detected by the pipe temperature sensor 17 and a cabin detected by the room temperature sensor 18. The room temperature in 5 is input. The controller 16 has a function of setting mode switching means capable of switching between a cooling mode, a heating mode and an intermediate mode according to the pipe temperature of the branch pipe 3 detected by the pipe temperature sensor 17. Further, the controller 16 controls the temperature of the fan coil motor 14 or the adjusting valve 13 so that the set temperature set by the dial 23 of the control unit 22 described later matches the room temperature detected by the room temperature sensor 18. It has the function of control means. The controller 16 includes:
Switch between setting mode, test mode and confirmation mode,
An expander 19, an energy saving key 20, and a remote signal generator 21 which are not used during normal operation are connected.

A control unit 22 is mounted on a night panel or the like and has a dial 23 as setting means. Reference numeral 24 denotes lighting means as setting mode display means. The lighting means 24 is provided in the vicinity of the dial 23 and has a tube temperature sensor 1
According to the temperature detected at 7, for example, the light is colored green in the cooling mode, orange in the intermediate mode, and red in the heating mode.

When the controller 16 determines that the tube temperature is equal to or lower than the predetermined temperature and is in the cooling mode, the dial 23
Is set to, for example, 25 ° C. At this time, by rotating the dial 23, the set temperature can be changed and set around the reference set temperature as needed (see FIG. 4). Similarly, when the controller 16 determines that the tube temperature is within the predetermined range and the mode is the intermediate mode,
The temperature control is canceled, the middle portion of the dial 23 is set to medium wind, and both ends are set to low wind and strong wind (FIG. 5).
See). Also, as shown in FIG.
However, if it is determined that the tube temperature is equal to or higher than the predetermined temperature and the mode is the heating mode, the reference set temperature at the appropriate temperature position provided at the intermediate portion of the dial 23 is set to, for example, 24 ° C. At this time, by rotating the dial 23, the set temperature can be appropriately changed and set around the reference set temperature.

When the dial 23 is turned off and a remote signal is turned on by the remote signal generator 21, the operation is performed at the heat run temperature in each of the cooling and heating modes according to the input temperature of the tube temperature sensor 17, and the dial 23 is turned on. In this case, the operation is performed by setting the temperature of the control unit 22, and the above operation can be performed by the remote signal of the remote signal generation unit 21 even when the energy saving key 20 is turned off. Further, the dial 23 is designed to be operable as long as the energy saving key 20 is turned on even when the remote signal of the remote signal generator 21 is turned off.

The analog-type cabin temperature control device of this embodiment configured as described above has the following effects. 4, 5, and 6 described here indicate the temperature and the like around the dial 23, respectively, for the sake of explanation. Actually, MIN, MAX, and OFF are displayed.
Is displayed only, and is applied to any mode.

(A) In the cooling mode When the pipe temperature of the branch pipe 4 detected by the pipe temperature sensor 17 is determined to be in the cooling mode, the heat exchange fluid (cold water) flowing through the branch pipe 4 is supplied to the heat exchanger for cold water. 11 and returns to the branch pipe 8 via the adjustment valve 13. At this time, the control unit 2
The second lighting means 24 lights green (see FIG. 4).

Therefore, for example, when the operator in the cabin 5 operates the dial 23 to the middle part to set the set temperature in the cabin 5 to 25 ° C., the air volume of the fan coil motor 14 is controlled by the controller 16 to the room temperature sensor 18. When the temperature difference between the room temperature detected by the above and the set temperature is | 0 to 1 | ° C, the wind is weak; when the temperature is | 1 to 4 | ° C, the wind is medium;
In the case of, it is automatically switched to strong wind. When the set temperature and the room temperature match, the fan coil motor 14 stops if the control method of the apparatus is a motor. When the control method of the apparatus is a valve, the fan coil motor is kept constant by a weak wind, and at that time, the opening degree of the control valve 13 is adjusted to adjust the temperature. Further, even if the set temperature is changed by the dial 23, the same control as described above is performed, and the operation approaches the set temperature.

(B) In the intermediate mode When the pipe temperature of the branch pipe 4 detected by the pipe temperature sensor 17 is determined to be in the intermediate mode, a heat exchange fluid (fluid having a temperature slightly lower than hot water) flowing in the branch pipe 4. Passes through the hot water heat exchange section 12 and returns to the branch pipe 8 via the adjustment valve 13.
At this time, the lighting means 24 of the control unit 22 lights in orange (see FIG. 5). Further, when this mode is switched to the intermediate mode, the temperature control by the dial 23 is canceled, and the dial 23 has a function of merely switching the low, medium and strong winds.

(C) In the heating mode When the pipe temperature of the branch pipe 4 detected by the pipe temperature sensor 17 is determined to be in the heating mode, the heat exchange fluid (hot water) flowing in the branch pipe 4 is supplied to the heat exchange section for hot water. Through the control valve 13, the flow returns to the branch pipe 8. At this time, the control unit 2
The second lighting means 24 lights red (see FIG. 6).

Therefore, for example, when the operator in the cabin 5 operates the dial 23 to the middle part to set the set temperature in the cabin 5 to 24 ° C., the controller 16 controls the fan coil motor by the controller 16 as in the above control (a). 14 air volume,
When the temperature difference between the room temperature detected by the room temperature sensor 18 and the set temperature is │0-1 ℃, the wind is automatically weak when the temperature is │1-4 ℃ and the wind is strong when │4 │ or more ℃. Is switched to When the set temperature and the room temperature match, the fan coil motor 14 stops if the control method of the apparatus is a motor. When the control method of the apparatus is a valve, the fan coil motor is kept constant by a weak wind, and at that time, the opening degree of the control valve 13 is adjusted to adjust the temperature. Further, even if the set temperature is changed by the dial 23, the same control as described above is performed, and the operation approaches the set temperature.

The setting of the temperature at the intermediate portion of the dial 23 in (a) and (c) can be changed as appropriate.

As described above, in the analog cabin temperature control device according to the present embodiment, the same operation of the dial 23, that is, the ergonomic operation of turning the dial 23 to the right to increase the power, increases the all-season in the cabin. Air conditioning operation is easily performed.

In the temperature control in each of the cooling and heating modes, the air flow rate of the fan coil motor 14 is automatically switched according to the temperature difference between the set temperature by the dial 23 and the room temperature, so that the rising speed of the air conditioning is greatly improved. I do.

Further, the cooling mode, the heating mode, and the intermediate mode are displayed in different colors by the lighting means 24, so that the passengers in the room can easily know what the current air conditioning state is. Further, the tube temperature sensor 17 changes the temperature of the heat exchange fluid in a short period of time, for example, a change such that the temperature of the heat exchange fluid shifts to each mode at night.
In this case, the lock can be performed for a certain period of time so that the mode does not shift because the control method is hindered.

(Second Embodiment) As shown in FIG. 7, in this embodiment, a push button 3
In the point that 1-34 were provided, it was different from that of the first embodiment.
Other configurations are the same as those of the first embodiment.

Here, 31 is an off switch, 32 is a minimum switch, 33 is an intermediate switch, and 34 is a max switch. 35 to 37 are lighting means,
For example, it lights in green in the cooling mode, in orange in the intermediate mode, and in red in the heating mode.

Also in this case, in the cooling mode and the heating mode, the temperatures corresponding to the respective switches 32 to 34 are set, and the same control as in the first embodiment is executed.

In the intermediate mode, each switch 32
Are canceled, and the switches 32 to
At 34, switching between a weak wind, a medium wind and a strong wind can be performed. That is, in the intermediate mode, the air-conditioning mode is a controllable air-conditioning mode that is completely unrelated to the temperature control.

Although the embodiment has been described with reference to the drawings, the specific configuration is not limited to the embodiment, and any change or addition without departing from the gist of the present invention is included in the present invention. It is. For example, it is obvious that the control valve 13 in the first embodiment can be omitted and only the fan coil can be controlled.

In the cooling mode and the heating mode of the first embodiment, the temperature is controlled by the dial 23. However, when the dial 23 is turned to the MAX position, the operation may be switched to the strong wind operation regardless of the temperature.
