When troubleshooting split air conditioning systems be sure to check voltage to
A.
the indoor unit only
B.
both the indoor and outdoor units
C.
the outdoor unit only
Homework Answers
the Answer for the above question is
B.both the indoor and outdoor units
following table indicates the possible failures in in-door & out-door units of a Split-AC, associated with voltage(High or Low)
|
Unit |
Problem |
Possible Cause |
Remedy |
|
In-Door Unit |
The air conditioner does not react after it is powered ( after the plug is inserted, the buzzer does not sound and the remote startup has no response) |
The transformer connection is loose or has bad contact or the transformer has malfunction |
Fasten (tighten) the wiring; measure the output voltage of the transformer, if it is incorrect, change the transformer. |
|
Power voltage is too low |
Check the voltage. If it is lower than 10% of the rated voltage, check the cause, improve the power supply condition and add the stabilized voltage power supply. |
||
|
Out-Door Unit |
In the cooling and heating mode, the outdoor fan runs, but the compressor does not run |
The voltage is too low or too high |
Manostat (a device for automatically maintaining a constant pressure within an enclosure) is recommended. |
From the above information we can conclude that When troubleshooting split air conditioning systems be sure to check voltage to both indoor and outdoor Units.
Thank you, Have a Nice Day :)

Wac (elec) The diagram depicts a portion of a DX air-conditioning system that provides cooling to one zone in a building. The outdoor unit provides heat-rejection and includes the compressor and the condenser fan. The indoor-fan moves air from the conditioned zone, across the cooling coil, and then back to the conditioned zone. The indoor-fan (with directly coupled motor) is located within the air-stream. Electric power consumption of the indoor fan motor is denoted Wm. The electrical power supply for...

A 1500-kg air conditioning unit is being lifted by a crane onto the roof of a building. The unit starts on the ground and is raised straight up to a height of 12.0 m by a cable attached to the crane. The tension in the cable during the lift is 1.54 × 104 N. (Reminders: a free body diagram will probably be helpful, and work can be positive or negative.)

3. A cold storage facility is maintained at 20°F when the outside air temperature is 90°RF by an air conditioning unit operating as a cycle at steady state. The unit must remove 120,000 Btu/h continuously from the facility to maintain the required indoor temperature, and has a power input of 20 hp Determine: the actual coefficient of the air conditioning unit the minimum theoretical horsepower that would be required to operate a cooling unit under these conditions.

1. A firm is considering replacing the existing industrial air conditioning unit. They will pick one of two units. The first, the AC360, costs $26,081.00 to install, $5,081.00 to operate per year for 7 years at which time it will be sold for $7,075.00. The second, RayCool 8, costs $41,244.00 to install, $2,161.00 to operate per year for 5 years at which time it will be sold for $9,015.00. The firm’s cost of capital is 6.92%.

The Ajax Corporation manufactures compressors for commercial air conditioning systems. A new compressor design is being evaluated as a potential replacement for the most frequently used unit. The new design involves major changes that have the expected advantage of better operating efficiency. From the perspective of a typical user, the new compressor would have an increased investment of RM8,600 relative to the present unit, and an annual expense saving dependent upon the extent to which the design goal is met...
