Title of Invention
WIRELESS AIR CONDITIONER TROUBLESHOOTING SYSTEM
Related Science
Electronics engineering, particularly wireless troubleshooting tools for indoor and outdoor air conditioner units.
Background
Troubleshooting an air conditioning unit nowadays requires that the repairman asks for problem descriptions from the owner and makes direct observations. The repairman then formulates a hypothesis of the cause of the problem based on his own experience. He then examines, repairs or replaces components and parts based on that hypothesis. If the hypothesis turns out to be incorrect, the repair attempt is considered to be a waste of time. If parts were replaced, it would have incurred unnecessary component replacement cost.
Some air conditioners are able to display its operational status in a front display panel. Any abnormal status is shown on the panel so the repairman would be able to formulate a more accurate problem hypothesis. But if the panel shows signs of multiple problems, it is still up to the repairman to use his experience to determine what the problems may be. If the hypothesis is incorrect, the same problem arises where time and cost are wasted. To correctly analyze a problem, one needs to know all the air conditioner's working parameters. Status indication using blinking lights in the front display panel is simply not enough.
To obtain the necessary parameters, a system must be present to obtain and display those values at a given time. It should also be able to suggest preliminary and advanced courses of action. A monitoring unit could be attached to the air conditioner to obtain the necessary data for the repairman. A mobile telephone or other communications device could be used to receive the data. It would then show where the problem lies and what the root cause is. This will allow the repairman to fix the problem accurately and reduce any wasted time and cost.
Nature and Purpose of Invention
The objective of this invention is to create a wireless air conditioner troubleshooting system that is able to identify the location and the cause of a problem. This will allow for a more accurate repair, reduce repair time, and reduce the repair cost.
This invention is a system that could be connected to an air conditioner to monitor its operational status. The status is used for maintenance or repair purposes, applicable to both to
the indoor and outdoor units. The system would relay the information wirelessly to a receiver such as a mobile telephone, a Wifi device, or other communications devices. The data is then displayed on those devices for the repairman to view and analyze, resulting in a more accurate, convenient, and faster repair.

Detailed Description of Invention
Figures 1 and 2 show this invention, the wireless air conditioner troubleshooting system, connected to the indoor and outdoor air conditioning units, respectively. The system could be monitored and controlled via a mobile wireless device. The system comprises a monitoring unit (3), the connection to the indoor air conditioning unit (5), the points of connection (4), the connection to the outdoor unit (6), and the points of connection (7). The monitoring unit processes the data obtained from the air conditioner and sends it wirelessly (2) to the receiving device (1), which displays the data. The wireless medium could be infrared, Wifi, Bluetooth or radio signals that the receiving device (1) is able to receive. The receiving device include a mobile telephone, a tablet, a computer, an infrared receiver unit, or a radio receiver with a display panel.
It is also possible to add a display to the monitoring unit (3) to show the air conditioner's various parameters, in a similar fashion to what is displayed on the wireless receiver device (1).
Figure 310 shows a block diagram of this wireless air conditioner troubleshooting system. The blocks show the components of the monitoring unit (3) that is connected to the air conditioner. Each of the connecting cables has conductive clamp end. The cables comprise a line cable (300), a neutron cable (301), and a communications cable (302). The line (300) and neutron (301) cables are connected to a power source (303) that powers the components. The
communications cable (302) is connected to the communications circuitry (306) that receives data from the air conditioning unit. The data contains information such as the ambient room temperature, the outside temperature, cooling fluid pressure, compressor status, etc. The data is sent to the processing unit (304), to the memory (305), to the wireless communication circuitry (307) and is finally transmitted to the receiving device (1 ).
Figure 4 shows the receiving unit as it receives the data and displays it to the repairman for problem analysis and resolution. The displays shows servicing-related data (150) and the status and parameters (151) of the circuitry of the outdoor unit, which includes the operational status of the compressor (active or inactive), the compressor motor frequency, demand load, and the voltages and currents inside of the air conditioner at that given moment. Other status and parameters (152) show the temperatures of the outdoor unit, the compressor, the tubing, and the ambient temperature. Other data being displayed include the relative humidity, mode of operation (hot or cold), fan operation of the outdoor unit, and the position of the expansion valve.
The fault section (153) shows any abnormal status of the air conditioner. Faults are shown as colored lights. For example, a red light indicates a fault in one of the components. In this manner, the operational status of all major components could be shown at the same time. The code section (154) shows a code related to the fault, such as the number of blinking status lights on the indoor unit's display panel (5). The detail section (155) shows the fault details. If there is more than one fault, the first one detected by the system is displayed first, followed by the next ones in sequence.
Any improvements to this system could be implemented by an expert in this field within the boundaries and objectives of this invention as described and granted by this patent. Best Method of Construction
