Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to trial run control for forcibly operating a compressor during installation or service of an air conditioner.

Conventionally, when installing an air conditioner or servicing an air conditioner when an abnormality occurs, the operating status is checked by mechanically turning on the room temperature controller and forcing the compressor to operate. This control is as shown in the electrical circuit diagram of FIG. In Figure 1, 1 is a power switch, 2 is an indoor blower, 3 is a trial run switch, 4 is a room temperature controller, 5 is a compressor, 6 is a
indicates an outdoor blower, and when the power switch 1 is turned on, the indoor blower 2 is operated. If you turn on the trial run switch 3, the room temperature controller 4 will be forced on.
It is equivalent to the compressor 5 and outdoor blower 6.
The system is used to operate the vehicle.

However, when this method is adopted, for example, the user may turn on the trial run switch 3 when installing or servicing the air conditioner, and then forget to turn it off when using the air conditioner.
Or, if you do not know how to use it and use it during a trial run, the compressor 5 will be forced to operate and the room temperature will drop so much that the air conditioner will not function as intended, and it will become too cold and may cause serious damage to the human body. It has a negative impact on Furthermore, wall-mounted air conditioners and other air conditioners installed in high positions that employ remote control devices have drawbacks such as forgetting to turn on the test run switch 3, and improvements are needed.

The present invention has been devised to solve the above-mentioned conventional drawbacks, and when the trial run input means is turned on, the compressor is forcibly operated, and after that, if a signal for switching the operating state is received, The forced operation of the compressor is canceled and the test run input means is automatically released.

An embodiment of the present invention will be shown below, but since the transmitting/receiving device, refrigeration cycle equipment configuration, etc. may be well-known ones, illustration and description thereof will be omitted.

FIG. 2 is a block diagram of an air conditioner operation control device according to the present invention. This air conditioner operation control device includes a controller 7 consisting of a microcomputer or the like, an input means 10 that receives input via a transmitter 8 and a receiver 9, a trial run input means 11 that receives direct input, and a room temperature detector. 12, a data memory 14 for storing test run modes, etc., and a control means 15 for controlling the compressor and blower.

An example of controlling an air conditioner is shown below using flowcharts shown in FIGS. 2, 3, and 4. A signal for switching the operating state is input from input means 10 to controller 7 via transmitter 8 and receiver 9. Also, almost at the same time, the room temperature data is also determined by comparison means 1.
3 is input by the output temperature signal from 3. Then, the air conditioner is controlled by the controller 7 and the control means 15 in a certain sequence. In addition,
When operating the air conditioner in the test run mode during installation or service, the test run input means 11 is turned on as shown in FIG. At this time, controller 7
is the state of the trial run input means 11 and the data memory 1.
Judging from the contents of 4, the trial run input means 11
After confirming that it has changed from OFF to ON, the test run mode is stored in the data memory 14. At this time,
The controller 7 switches the room temperature detector 12 from the normal mode according to the mode stored in the data memory 14.
The compressor is forcibly switched to a test run mode in which the compressor is operated irrespective of the determination and comparison means 13. When the trial run input means 11 is turned off, the controller 7 cancels the trial run mode of the data memory 14 and switches to the normal mode in which room temperature control is performed. In addition, in the trial run mode, if a signal for switching the operating state, such as changing the set temperature or air volume, is input from the input means 10, the controller detects that the trial run input means 11 is ON as shown in FIG. However, it will switch to normal mode. In this normal mode, the test run input means 11 is turned OFF once, and the data memory 14 is turned off until it is turned ON again.
is memorized.

As described above in detail, the air conditioner operation control device of the present invention includes a determination/input means for controlling the room temperature, and a trial run input means for inputting information for forcibly operating the compressor. , an input means for inputting information for switching the operating state, a controller for controlling the air conditioner using information from each of these means, and a control means for controlling the air conditioner using signals from the controller,
The controller includes a means for forcibly operating the compressor based on an input from the test run input means, and a means for forcibly operating the compressor based on an input from the test run input means during forced operation or an input from the input means. Since the test run is started by turning on the test run input means, and is canceled by either the OFF signal of the test run input means or the signal from the input means,
It is possible to prevent the machine from being accidentally operated after a trial run, to prevent it from becoming too cold, and to have no adverse effects on the human body.
