Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an air conditioner that air-conditions a working room, and more particularly to a wireless air conditioner that eliminates control lines and wirelessly transmits and receives control signals.

(Prior Art) A conventional air conditioner has a control system consisting of independent sensors such as a temperature sensor and a humidity sensor, and a main body control device. This was a rare occurrence because it was designed to send a signal to the main body control device.

For this reason, in general, the actual location where air conditioning is desired and the sensor position are far apart, resulting in poor control accuracy at the location where air conditioning is desired. The problem was that the air conditioning near the engine intake became inaccurate, making it difficult to obtain reliable data.

In addition, in order to prevent such deterioration of control accuracy, it is often necessary to increase the number of air circulations, change the mounting position of sensors each time, or switch multiple sensors. However, increasing the number of air circulations requires large-capacity fans and air conditioners, raising equipment costs and running costs, and changing the mounting position of sensors requires wired connections. Various problems were inherent, such as the need for a certain amount of troublesome work, and the additional cost of new equipment required to install multiple sensors.

(Object of the Invention) In view of the problems of the prior art described above, the present invention provides a wireless air conditioning system that enables sensors to be moved and installed in any location, thereby greatly contributing to improving air conditioning control accuracy and reducing equipment costs. The purpose is to provide equipment.

(Structure of the Invention) The purpose of this invention is to install sensors all at once and to build a built-in power supply, so that the signals from the sensors can be compared and converted with set values, and a control signal can be output from the transmitting antenna. It is equipped with a portable sensor unit and a receiving unit that receives the control signal via a receiving antenna to drive and control the air conditioner and outside air damper, and the sensors can be installed anywhere in the work room where air conditioning is desired. This is achieved by a wireless air conditioner that can control the air conditioner (by wireless transmission and reception).

(Example) Hereinafter, an example of the present invention will be described based on the accompanying drawings.

In FIG. 1, reference numeral 1 denotes an air conditioning work room, and an air conditioner 4 is connected to the air conditioning work room 1 via an air supply duct 2 and a return duct 3. The air conditioner 4 is a conventional one, and includes a filter 5, a cold water coil 6, a reheating coil 7, and a humidifier 8 from the downstream side to the secondary side. and,
The air conditioner 4 includes a control valve 9 that controls the supply of cold water to the cold water coil 6, a control valve 1o that controls the supply of steam to the reheat coil, and a control valve 1o that controls the supply of steam to the humidifier 8. A solenoid valve 11 for control is also attached. Further, an outside air duct 12 is connected to the primary side of the air conditioner 4, and an outside air damper 14 that is opened and closed by a damper drive device 13 is interposed in the middle of this outside air duct 12.

A sensor unit 15 is installed in the air-conditioning work room 1 to which sensors to be described later are collectively attached. This sensor 27) is attached with a 15tllFt antenna 16), and outputs a control signal to be described later through the transmitting antenna 16. - 10,000, a receiving antenna 17 for receiving the control signal oscillated from the transmitting antenna 16 is installed at an appropriate location within the air conditioning work M1, and is further connected to the receiving antenna 17 by a wiring 18 outside the air conditioning work N1. A receiving unit) 19 is installed. The receiving unit 19 corresponds to a conventional main body control device, and includes the two control valves 9, 10,
Solenoid valve 11, damper drive device 13 and each arrangement 1j
20 to control their drive.

Note that 21 is a fan installed in the air supply duct 2, and 22 is a steam trap attached to the air conditioner 4.

Here, as shown in detail in FIG. 2, the sensor unit 15 includes a temperature sensor 24, a humidity sensor 25, a dust sensor 26, etc. on one side of the casing 23. Co,
In addition to installing sensors such as the sensor 27 all at once, an amplifier 28 is installed in the casing 23 to amplify the signals from the sensors 24 to 27, and the signal amplified by the amplifier 28 is compared with a set value and converted into a control signal. It incorporates a converter 29 that outputs a signal, a transmitter 30 that transmits a control signal from the converter 29 via the transmitting antenna 16, and a power supply device 31 that serves as an operating source for each part. .

Further, as shown in detail in FIG. 13, the receiving unit 19 includes a receiver 32 that directly receives the control signal received by the receiving antenna 17, and an amplifier 33 that amplifies the control signal received by the receiver 32. , and a control section 34 that drives and controls the control valves 9, 10, etc. based on the control signal amplified by the amplifier 33, and is provided with a cable 35 for receiving external power.

Depending on the configuration, in order to air condition the air conditioning work room 1,
In advance, the sensor unit 15 is moved and installed in a place where air conditioning is actually desired, and temperature, humidity, CO8, and dust are set to predetermined values. Then, when the fan 21 is driven, outside air whose air volume is adjusted by the outside air damper 14 is taken into the air conditioner 4 through the outside air duct 12, and return air from the air conditioning work room 1 taken in through the return duct 3 is returned. It can be mixed with.

The air-fuel mixture is adjusted to a predetermined temperature while passing through the filter 5, cold water coil 6, and reheating coil 7 in the air conditioner 4, and is further added with a predetermined humidity by the humidifier 8, after which it is sent to the air supply duct. 2 into the air-conditioning work room 1, and the air-conditioning work room 1
The inside gradually comes to have the predetermined atmospheric conditions.

However, the sensors 24 to 27 of the sensor unit 15 continuously detect atmospheric conditions such as temperature and humidity, including during work, and now if these conditions become different from the set value, A control signal is output from the sensor unit 15, and in response to this, the receiving unit 19 activates the control valve 9.1.
The atmosphere is adjusted by driving and controlling the 0 etc. Kao, CO
, and the ducts are controlled by adjusting the opening degree of the outside air ductper 14.

(Effects of the Invention) As described above in detail, the present air conditioner is equipped with a portable sensor unit that mounts sensors all at once and has a built-in power supply, and a receiving unit that drives and controls the air conditioner and outside air damper. This allows the air conditioning to be controlled by wirelessly transmitting and receiving control signals between the two, which eliminates the need for control lines and allows sensors to be sent to any location or to control the air conditioning at the membership location. (As a result, the number of air circulations can be reduced), and the use of small fans and air conditioners has the effect of reducing equipment costs and running costs. By using the above-mentioned portable sensor unit, it is no longer necessary to change or install multiple sensors, thereby reducing equipment costs.
