Definitions
- the present disclosure relates to a method for probing pipes of an air conditioner.
- an air conditioner heats and cools an indoor space by circulating a refrigerant.
- the air conditioner is classified into a single type air conditioner and a rrulti type air conditioner in accordance with the number of indoor units connected to each other.
- the single-type air conditioner has one outdoor unit and one indoor unit connected to the outdoor unit.
- the multi-type air conditioner has a plurality of indoor units connected to an outdoor unit.
- the multi-type air conditioner includes a dispenser for dispensing the refrigerant to the plurality of indoor units.
- a dispenser for dispensing the refrigerant to the plurality of indoor units.
- a plurality of dispensers may be provided.
- each of the dispensers has a plurality of valves and a pipe is connected to each of the valves.
- the indoor unit is connected to each pipe.
- the multi type air conditioner is classified into a switched air conditioner and a synchronous air conditioner in accordance with a refrigerant flow method.
- the switched air conditioner the indoor unit is switched from a cooling mode operation to a heating mode operation or vice versa.
- the synchronous air conditioner some of the indoor units operate with the heating mode and others operate with the cooling mode.
- test run After the air conditioner is installed on a building, a test run is performed before performing a normal operation. In the test run, a pipe probing run for probing pipes connected to respective indoor units is performed. By performing the pipe probing run, it becomes possible to individually control the indoor units.
- a pipe probing method of a multi-type air conditioner of a related art has following problems.
- the multi-type air conditioner performs the pipe probing for the indoor units one by one by controlling valves that are arranged on one pipe. Therefore, when there are many interconnected indoor units, the probing time increases significantly. Furthermore, after the pipe probing is completed for one indoor unit, the refrigerant cycle should be stopped for a predetermined time so that a temperature of the indoor unit that is probed can be almost same as that of other indoor units. Therefore, the overall pipe probing time further increases. This causes the increase of the overall test run time of the air conditioner. Disclosure of Invention Technical Problem
