Abstract

PROBLEM TO BE SOLVED: To appropriately control temperature in a guest room being utilized by an unspecified user by switching a management operation mode based on a management target temperature being set by a manager and a generic temperature-adjustment mode based on an indoor target temperature where the user of the guest room can arbitrarily set for controlling the room temperature. SOLUTION: A temperature-controlling device 1 has a first-setting function part 2 where a manager can set an arbitrary management target temperature, and a second-setting function part 3 where the user of a guest room (an unspecified one) can set an arbitrary indoor target temperature. When the user does not require particular temperature conditions or the room is not used, a control part 4 performs control based on the management target temperature in a management operation mode. When the user of the guest room feels hot or cold, the second-setting mechanism 3 is operated for setting the arbitrary indoor target temperature, thus changing the mode to a generic temperature-adjusting one. The control part 4 allows the management operation mode to be automatically reset after a specific amount of time passes from the time when the second-setting function part 3 is manually set or at the specific time, thus maintaining control due to the appropriate management target temperature being set by the manager.

Next, the overall operation and functions of the floor heating system including the temperature control device 1 will be described with reference to FIGS.

A specific person such as a building equipment manager sets an optimum heating temperature (for example, 25 ° C.) desirable for operation of the heating equipment as a management target temperature in the first setting function unit 2 (FIG. 3: Step A). ), The upper limit (for example, 50 ° C.) of the floor surface temperature is set in the first setting function unit 2 in order to prevent the floor surface temperature from being overheated. The specific person also starts the heating operation in the control mode (general temperature control mode) based on the arbitrary target heating temperature (indoor target temperature) set in the second setting function unit 3 and then starts the first setting function unit The time to return to the heating operation in the control mode (management operation mode) based on the target heating temperature (management target temperature) set to 2 is set in the first setting function unit 2. The settable return time is a concept including both a time interval until the return time and a time to be returned. For example, the time interval is 8 hours and the time is 0:
00, etc., and when both of these two conditions are satisfied, or when at least one of the two conditions is satisfied, the temperature control device 1 is forcibly switched from the general temperature control mode to the management operation mode. Can be configured.

Thus, when the cabin user does not request a special heating temperature condition, or when the room is vacant, the temperature control device 1 sets the temperature condition (the control target temperature) set in the first setting function unit 2. ) Is carried out (FIG. 3: step B). That is, the control unit 4 operates the motor 27,
The pump 19 is driven, and the secondary heat medium circulates through the floor heating circuit 17. High temperature primary heat carrier (hot water or high temperature liquid, etc.)
Is supplied from the supply line 14 to the heat exchanger 12, and the heat exchange action between the primary heat medium flowing through the primary heat source unit of the heat exchanger 12 and the secondary heat medium flowing through the secondary heat source unit of the heat exchanger 12 Thereby, the secondary heat medium is heated to a high temperature range. The secondary heat medium heated by the heat exchanger 12 is supplied to the on-off valve 18 → the pump 19 → the supply pipe 20 → the hot water pipe 25.
… → Reverse pipe 23r → Return pipe 23 → Check valve 22 →
The opening / closing valve 21 circulates through a heat medium circulating circuit comprising a secondary heat source unit of the heat exchanger 12, and heats the floor surface F through a heat exchange action between the hot water pipes 25 and the floor constituent material. Based on the room temperature data detected by the room temperature sensor 34, the control unit 4 controls the motor 27 to turn on and off, and controls the room temperature to a set temperature condition (management target temperature). Based feedback control of the floor heating system is performed.

When the room temperature is equal to the management target temperature (for example, 25
° C) or lower, but the floor temperature sensor 35
If the floor surface temperature detected at the time exceeds the overheating prevention temperature (for example, 50 ° C.), the control unit 4 stops the operation of the motor 27, stops the circulation of the secondary heat medium, and Stop or interrupt heating. Thus, the temperature control device 1
Controls the floor temperature in preference to the room temperature to prevent an excessive rise in floor temperature.

The guest room guest (customer) may respond to the management target temperature (for example, 25 ° C.) set by the manager.
When the user feels heat or cold, the guest room user can set an arbitrary required heating temperature by operating the second setting function unit 3. That is, the guest room user operates the operation button 33c of the operation panel 33p provided on the temperature controller 33,
An arbitrary indoor target temperature (for example, 28 ° C.) can be manually set (FIG. 3: Step C). As a result,
The control unit 4 gives priority to the temperature setting condition of the second setting function unit 3, controls the floor heating system based on the temperature condition, and sets the indoor temperature to the manually set temperature (indoor target temperature: 28 ° C).
The feedback control of the floor heating system is executed so as to adjust the temperature (FIG. 3: Step D). The control unit 4 further includes
The temperature of the first setting function unit 2 is set at a predetermined time, for example, after a lapse of a predetermined time, for example, 8 hours from the manual setting time of the second setting function unit 3, or at a predetermined time such as 0:00 am The heating operation in the management operation mode based on the set conditions is automatically returned, and after the return from the management operation mode, the feedback control of the management operation mode is executed again as described above so that the room temperature converges to 25 ° C. (FIG. 3) : Steps E and F).

[0023] Thus, when the guest room goes to bed with the manual setting temperature set to an excessively high temperature due to, for example, an erroneous operation of the temperature controller in a drunken state, Even if an abnormal heating operation under the general temperature control mode is performed, for example, when a manually set temperature is set in a high temperature range, the temperature control device 1 forcibly returns to the management operation mode at a predetermined time. Accordingly, the transient abnormal operation of the floor heating system is forcibly stopped, and the control based on the appropriate management target temperature set by the administrator is maintained and managed. Therefore, the floor heating system having the above-described configuration that forcibly returns to the appropriate heating operation mode at the set time can prevent an unexpected situation in which an abnormally high temperature atmosphere or the like in the room occurs, and also enables the guest room to perform the heating operation at the time of the tucking out. After stopping the operation, it is possible to avoid an undesired situation such as the next guest room feeling abnormal cold when entering the room.

Further, an arbitrary freezing prevention temperature is set in the antifreezing temperature setting function unit 5 constituting the first setting function unit 2, and the control unit 4 executes control for preventing the floor heating system from freezing. . Such an anti-freezing operation is performed according to a conventional method, such as a forced circulation of the heat medium in the heat medium main pipe system and / or the floor heating circuit 17. Further, the control unit 4 associated with a timing unit such as a timer can also function as a control unit of the night preheating operation of the floor heating system, for example, by setting a set temperature at night to a desired preheating temperature.

In the present embodiment, the temperature controller 33 of the temperature control device 1 has a display unit for displaying the on / off state of the motor 27, and has an allowable range of temperature conditions that can be set by the passenger, ie, A function is provided for setting an upper limit (maximum temperature) and a lower limit (minimum temperature) of the heating temperature.
