Embodiments of the method of the present invention will be specifically described with reference to the drawings. FIG. 1 is a schematic configuration diagram of equipment for carrying out the method of the present invention. Reference numeral 1 is a fan coil unit in which a fan 2 and a heat exchanger 3 are housed in a casing, which is installed near the ceiling of each guest room of a hotel. The room temperature is adjusted by adjusting the amount of cold water or hot water passing through the heat exchanger 3 or adjusting the amount of conditioned air blown into the room. This adjustment
This is an air-conditioning system that is currently adopted in a general hotel, which is operated by each hotel guest so as to reach the optimum room temperature by operating the knob of the control panel A provided on the night table or by remote control operation.

FIG. 2 is a schematic explanatory view of the simplest operation control device in which the air-conditioning operation is automatically started when the customer enters the passenger room and is automatically stopped when the passenger leaves the passenger room, that is, when the customer leaves the room. Reference numeral 4 denotes a conventionally known switch box for controlling electric lights, which is attached to the wall surface in the passenger compartment, and the user unlocks the corresponding passenger compartment with the key K passed at the front desk and then enters the key. The room light cannot be turned on unless the room number display plate K1 attached to the box is inserted into the box 4. Therefore, when the key display plate K1 is inserted into the switch box 4, the fan coil unit 1 is turned on,
If you turn off the power when you remove the display board,
Whenever a customer enters the room, the key display board is inserted into the switch box 4 to turn on the light.
This operation starts the air conditioning operation, and when leaving the room, the key is taken out of the switch box and taken out, so that this operation stops the air conditioning operation.

When the guest room is a single room, two sets of light projectors and light receivers are provided in the passage from the entrance to the guest room, and the entrance and exit of the passengers are detected from the light-shielded order to start the air conditioning operation. It may be possible to control the stop, or when pulling out the key from the key box to the customer at the front desk,
When this is regarded as entering the room, a signal is sent to start the air conditioning operation of the corresponding guest room, and when the customer temporarily deposits the key at the front desk or returns it, it is regarded as leaving the room and sends a signal. Alternatively, the air conditioning operation may be stopped.

FIG. 3 is a schematic explanatory view of an operation mode switching device for changing the operation mode of the fan coil unit when the customer turns off the light or lowers the illuminance for sleeping. The illuminance meter built into the control panel A of the table together with the timer T constantly measures the illuminance in the room after confirming that the customer is in the room. Whether the light switch on the night table is turned off or not. , When the illuminance control knob is adjusted to reduce the illuminance in the room, and when the illuminance at that time is less than or equal to the illuminance preset in the illuminance meter L, the timer T is activated and the illuminance decrease state is maintained for a certain period of time, for example Then, the operation mode switching signal U is output, and the timer T is reset when the illuminance is restored before a certain period of time elapses.

The signal U is input to a control circuit provided in the fan coil unit 1, and the operation mode of the fan coil unit is switched to a sleep mode different from that during normal air conditioning. This sleep mode is an operation mode independent of the normal operation mode, and the rotation speed of the fan 2, the room temperature, the conditioned air blowing amount and other air conditioning conditions are preset so as to satisfy the conditions suitable for sleeping.

Key K handed by the hotel guest at the front desk
After unlocking the door lock of the guest room to be used using and entering the room, insert the display board K1 attached to the key into the switch box 4 mounted on the wall to light up,
At the same time as the lighting, the drive power is applied to the fan coil unit 1 to start the air conditioning operation. The operation in this case is a normal operation, and each customer operates the control panel A by picking or operating the remote controller to adjust the room temperature to obtain an optimum room temperature. When the user leaves the room, that is, when he / she leaves the room, the key K, that is, the display board K1 must be taken out from the switch box 4 and taken out, so that the driving power to the fan coil unit 1 is cut off at the same time when the light is turned off. , Air conditioning operation is stopped.

When the customer turns off the light or lowers the illuminance for sleeping, the comparison circuit in the illuminance meter L measuring the illuminance in the room after the customer's entry is confirmed is compared with the illuminance at that time. When the preset illuminance is compared and it is determined that the illuminance is equal to or less than the set illuminance, an operation signal is transmitted to the timer T. Timer T
Is started by this signal and outputs the operation mode switching signal U after a lapse of a certain time. When the illuminance in the room is restored before this time elapses, the timer T is reset without outputting the signal U. When the signal U is input to the control device of the fan coil unit 1, the switching circuit in the control device operates to switch the operation mode of the fan coil unit 1 from the normal operation mode to the sleeping mode. Is driven in sleep mode.

The sleep mode may be switched to the normal operation mode by recovering the indoor illuminance, but it may be inconvenient if the outside becomes bright during sleep and the mode is automatically switched to the normal operation mode. Therefore, the user may input the wake-up time to the setting device in advance and switch to the normal operation mode 10 to 30 minutes before the time, and control from the front desk by wire or wirelessly during the wake-up call. You can do it.

In recent years, more and more hotels have adopted a card-type key for controlling the opening and closing of the door locking device, and in particular, the so-called IC key using an IC with a large storage capacity is used to open and close the original door locking device. When using a paid facility or facility in the hotel other than control, it is necessary to insert the IC key into the key reader / writer provided for each facility or facility so that it cannot be used, and when the facility or facility is used IC
An increasing number of hotels have adopted a system in which the usage time and fee are entered in the key storage section and the IC key is paid back when the hotel returns to the front desk. If this IC key is used as the key shown in the embodiment of the method of the present invention and the key box is used as a key reader / writer, the heating / cooling conditions specified by the customer when the IC key is issued at the front are input, It is convenient because the user does not need to set the temperature one by one, and it is convenient even when collecting the heating and cooling usage fee.
