Definitions

  • the present invention relates to a method, as defined by appended independent claim 1, of determining the refrigerant conduit connections between indoor units and control valves in a multi air conditioner system comprising an outdoor unit, a plurality of indoor unit, a plurality of refrigerant paths between the indoor units to the outdoor unit and refrigerant control valves in respective ones of said refrigerant paths.
  • the present invention also relates to a multi air conditioner system as defined by appended independent claim 9 comprising a controller (18) configured to carry out the above method.
  • a conventional multi air conditioner system comprises an outdoor unit, a plurality of indoor units connected in parallel to the outdoor unit, communication lines connected between the outdoor unit and the respective indoor units, power cables and refrigerant pipes.
  • the outdoor unit comprises a compressor, an outdoor heat exchanger and a plurality of motor-operated valves mounted in the refrigerant pipes.
  • An example of the conventional multi air conditioner system is disclosed in KR-A-1998-025714 .
  • an engineer When initially installing a conventional multi air conditioner system, as described above, an engineer connects the indoor units to the outdoor unit by the communication lines, the power cables and the refrigerant pipes. After that, the engineer measures the difference in temperature between the indoor units while opening and closing the motor-operated valves during cooling operation in order to determine which indoor units are connected to which respective refrigerant pipes (or the motor-operated valves).
  • cooling operation is carried out for determining how the indoor units are connected. This can result in the system becoming damaged. Specifically, the amount of refrigerant condensed in the outdoor heat exchanger is increased when the pipe connection determination is being performed in this way when the outdoor temperature is low.
  • the condensed refrigerant may not be sufficiently evaporated by the indoor heat exchangers and, therefore, the refrigerant is introduced into the compressor in a liquid state, which is harmful to the compressor.
  • JP7305879 relates to comparing an outdoor temperature to a threshold, and operating an indoor unit to either heat or cool depending on that comparison. In this way erroneous wiring can be discovered.
  • EP0678718 relates to automatically setting an address of an exterior device.
  • JP 2001 289480 relates to reducing the time required to check wiring in a multi-room air conditioner. Control vales are successively opened and temperature changes of the heat exchangers are discriminated.
  • An aspect of the present invention is a method of determining the refrigerant conduit connections between indoor units and control valves in a multi air conditioner system according to claim 1.
  • Another aspect of the present invention is a multi air conditioner system according to claim 9.
  • a multi air conditioner system comprises an outdoor unit 10, first to fourth indoor units 30, 40, 50, 60, connected to the outdoor unit 10, and a distributor 70 having first to fourth motor-operated valves 71, 72, 73, 74.
  • the outdoor unit 10 comprises a compressor 11 for compressing refrigerant, a four-way valve 12 for guiding the refrigerant flow, discharged from the compressor 11, an outdoor heat exchanger 13 which receives compressed refrigerant from the compressor 11, an outdoor fan 14 for forcibly blowing air across or through the outdoor heat exchanger 13 and an outdoor fan motor 15.
  • the outdoor unit 10 further comprises an outdoor temperature sensor 16 for measuring the outdoor temperature, an accumulator 17 for delivering gaseous refrigerant to the compressor 11, an outdoor unit microcomputer 18 for controlling the various components of the outdoor unit 10 and performing data communication with indoor unit microcomputers 36, 46, 56, 66, which are described below in detail; and a display part 19 for displaying the state of the multi air conditioner system.
  • the first to fourth indoor units 30, 40, 50, 60 comprise first to fourth indoor heat exchangers 31, 41, 51, 61 for performing heat exchange with introduced indoor air; first to fourth indoor fans 32, 42, 52, 62 for introducing indoor air into the first to fourth indoor units 30, 40, 50, 60, guiding the introduced air through the first to fourth indoor heat exchangers 31, 41, 51, 61 and discharging the air out of the first to fourth indoor units 30, 40, 50, 60, and first to fourth indoor fan motors 33, 43, 53, 63 for rotating the first to fourth indoor fans 32, 42, 52, 62.
  • the first to fourth indoor units 30, 40, 50, 60 further comprise first to fourth inlet temperature sensors 34, 44, 54, 64 mounted to pipes connected to the first to fourth indoor heat exchangers 31, 41, 51, 61, through which refrigerant is introduced (when performing a cooling operation), and first to fourth indoor unit microcomputers 36, 46, 56, 66 for controlling the respective components of the first to fourth indoor units 30, 40, 50, 60 and performing data communication with the outdoor unit microcomputer 18.
  • the first to fourth motor-operated valves 71, 72, 73, 74, mounted in the distributor 70, are connected to the first to fourth indoor units 30, 40, 50, 60 via refrigerant pipes to control the refrigerant flow rate into the first to fourth indoor units 30, 40, 50, 60.
  • the outdoor temperature sensor 16 measures outdoor temperature (80) to determine whether the measured outdoor temperature is higher than or equal to a reference temperature (82). If the outdoor temperature is higher than or equal to the reference temperature, cooling is performed (84). If the outdoor temperature is lower than the reference temperature, heating is performed (85).
  • the operating levels of the compressor 11, the outdoor fan 15 and the first to fourth indoor fans 32, 42, 52, 62 are appropriately controlled, according to operation modes, and the first to fourth motor-operated valves 71, 72, 73, 74 are maintained open at predetermined initial levels (86).
  • the temperatures at the inlets of the indoor units are measured by the first to fourth inlet temperature sensors 34, 44, 54, 64 respectively and the measured temperatures are stored (88). At this time, the temperatures at the inlets of the indoor units are temperate at the inlets of the respective indoor heat exchangers (based on the cooling operation).
  • the first motor-operated valve 71 is closed, while the other motor-operated valves 72, 73 and 74 remain open by an unchanged amount (90 and 92).
  • the temperatures at the inlets of the indoor units are measured again (94).
  • the predetermined period of time is set so that a change in temperature, resulting from the closing of the first motor-operated valve 25, is apparent.
  • the differences between temperatures at the inlets of the indoor units before closing the first motor-operated valve 71 and temperatures at the inlets of the indoor units after closing the first motor-operated valve 71 are calculated to determine whether there is an indoor unit where the temperature difference is more than a reference value (96). Such determination is made in order to prevent the temperature change at an indoor unit, where the inlet temperature has changed due to other causes than closing of the first motor-operated valve 71, from being incorrectly regarded as the indoor unit connected to the first motor-operated valve 71.
  • the reference value may be changed according to the system.
  • heating operation high-temperature refrigerant is not supplied to the indoor heat exchanger as the motor-operated valve is closed and, therefore, the temperature at the inlet of the indoor unit gradually decreases.
  • cooling operation low-temperature refrigerant is not supplied to the indoor heat exchanger as the motor-operated valve is closed and, therefore, the temperature at the inlet of the indoor unit gradually increases.
  • determination of whether the temperature at the inlet of the indoor unit has decreased more than the reference value, when the motor-operated valve is closed, is made when performing the pipe connection determination operation during heating operation, and determination as to whether the temperature at the inlet of the indoor unit has been increased more than the reference value as the motor-operated valve is closed is made when performing a pipe connection searching operation during the cooling operation.
  • the operation mode of the system is properly set depending on outdoor temperature when performing the pipe connection searching operation. Consequently, the present invention has the effect of preventing the pipe connection searching operation from being performed in improper operation modes, and therefore, preventing the system from being damaged.
