Definitions

  • the present invention relates to an air conditioner, and particularly to an air conditioner using an absorption type refrigerating machine and a fine coil unit.
  • the absorption type cold/hot water machine or the chiller heat source machine is used as a heat source machine
  • facilities such as a cooling water system, etc. are also required. Therefore, it is sufficient to use only one heat source machine, however, the number of places to which maintenance is required is larger than the case where the outdoor unit having the compressor is used as a heat source machine, and also it is impossible to dispersively set up the heat source machine.
  • the laying of the water pipe in the building must be replaced by the laying of the refrigerant pipe in the building, that is, the pipe laying is carried out again by using a water pipe, and also the fan coil unit must be replaced by the indoor unit.
  • US 5 272 885 A describes an air conditioner according to the preamble of claim 1 wherein during cooling operation the chiller unit serves as a condenser for the refrigerant and during heating operation as evaporator.
  • an obj ect of the present invention is to provide an air conditioner that is equipped with a heat source machine having a compressor therein and supplies heat source from both of a refrigerant pipe and a water pipe to carry out air conditioning operation.
  • the air conditioner is provided with the fan coil unit for circulating cold/hot water in a water pipe to carry out air conditioning operation and also the indoor unit for directly heat-exchanging the refrigerant discharged from the compressor with indoor air. Therefore, the fan coil unit which has been hitherto connected to the water pipe can be directly successively used, and also the air conditioning area can be expanded or the air conditioning performance can be improved by newly laying a refrigerant pipe. Furthermore, the newly laid pipe is the refrigerant pipe, and thus the laying cost in a building can be suppressed to a low cost.

  • a liquid pipe 5a extending from the outdoor unit 1 is connected to one end of the receiver tank 22, and the other end of the receiver tank 22 is branched to two parts at a branch point X.

  • one end of the water pipe 7b is branched and then connected to cold/hot water ports J, L of the refrigerant/water heat exchangers 20a, 20b while the other end of the water pipe 7b is branched and then connected to the other ends of the water heat exchangers 40a, 40b of the fan coil units 4a, 4b.

Therefore, when a heat source machine such as an absorption type refrigerating machine or the like is replaced by the air conditioner of this embodiment, water pipes which have been laid in a building can be successively used. Furthermore, even when an air conditioning area is newly enlarged or the air conditioning performance is improved, a refrigerant pipe for circulating refrigerant discharged from the compressor 11 may be laid, so that the laying cost of the pipe can be reduced to a small level.
  • indoor heat exchanges 30a, 30b for directly heat-exchanging the refrigerant discharged from the compressor 11 of the outdoor unit 1 with indoor air

  • the indoor controllers 32a, 32b for controlling the indoor units 3a, 3b respectively and carrying out communications with the outdoor controller 16 of the outdoor unit 1.
  • the fan coil units 4a, 4b are accommodated the water heat exchangers 40a, 40b for heat-exchanging indoor air with cold water or hot water generated in the chiller unit 2 and circulated by the circulating pump 6, and the cold/hot water valves 41a, 41b for controlling flow of the cold water or hot water flowing into the water heat exchangers 40a, 40b, which are connected to each other through the water pipes, and in the fan coil units 4a, 4b are also accommodated the fan coil controllers 42a, 42b for controlling the fan coil units 4a, 4b respectively and carrying out communications with the chiller controller 24 of the chiller unit 2, respectively.
  • a passage along which the refrigerant supplied from the chiller unit 2 to the using side heat exchangers 30 is heat-exchanged with the cold/hot water can be set to a long value, and thus the heat exchange efficiency between the refrigerant and the cold/hot water can be enhanced.

  • the opening degree of the motor-driven expansion valve 21 of the chiller unit 2 is controlled, and also the cold/hot water valves 41a, 41b of the fan coil units 4a, 4b,are opened, so that the refrigerant discharged from the compressor 11 flows through the four-way valve 12 into the outdoor heat exchanger 13, and the refrigerant is heat-exchanged with outside air and condensed in the outdoor heat exchanger 13.
  • the pressure of the refrigerant thus condensed is reduced in the outdoor expansion valve 14, and the pressure-reduced refrigerant flows into the receiver tank 22 of the chiller unit 2 and is temporarily stocked in the receiver tank 22. Thereafter, the refrigerant flows out from the receiver tank 22 and then it is distributed into two passages.
  • the refrigerant in one distributed passage flows through the refrigerant pipe 5b to the indoor units 3a, 3b.
  • the refrigerant in the other distributed passage flows through the check valve 23a to one port of the refrigerant heat exchanger 20c.
  • the refrigerant flowing into the refrigerant heat exchanger 20c is heat-exchanged with the refrigerant flowing through the refrigerant/water heat exchangers 20a, 20b, and then the refrigerant thus heat-exchanged passes through the motor-driven expansion valve 21 and flows into the refrigerant/water heat exchangers 20a, 20b successively to be evaporated, so that cold water is generated. Furthermore, the refrigerant flows into the other port of the refrigerant heat exchanger 20c and flows out to the refrigerant pipe 5c.

  • the cold water generated in the chiller unit 2 flows through the water pipe 7a by the driving of the circulating pump 6, and is branched into two streams. These refrigerant streams are passed through the cold/hot water valves 41a, 41b and heat-exchanged with indoor air in the water heat exchangers 40a, 40b, and then the refrigerant thus heat-exchanged with the indoor air is passed through the cold/hot water pipe 7b and returned to the chiller unit 2.
  • the indoor expansion valves 31a, 31b of the indoor units 3a, 3b are fully closed, and all the refrigerant discharged from the compressor 11 passes from the receiver tank 22 of the chiller unit 2 through the check valve 23a to the refrigerant heat-exchanger 20c, flows through the refrigerant/water heat exchangers 20a, 20b and then returns to the compressor 11.

  • plate type heat exchangers are used as the refrigerant/water heat exchangers 20a, 20b, and they have high heat-exchanger capabilities. Therefore, there is a risk that the refrigerant which flows from the gas pipe 5c side into the refrigerant/water heat exchangers 20a, 20b and is heat-exchanged with water trapped in the water pipes 7a, 7b to be condensed and then circulated in the refrigerant pipes 5a to 5c runs short temporarily, that is, an out-of-gas state may temporarily occur.
  • the circulating pump 6 is also driven to prevent the water trapped in the refrigerant/water heat exchangers 20a, 20b from being frozen.
  • step S1 it is judged whether the air conditioner 100 is driven or not. If the air conditioner 100 is not driven, the judgment of step S1 is repeated. If the air conditioner 100 is driven, it is judged whether both the fan coil units 4a, 4b are at a stop or under the termo-off operation (step S2). If anyone of the fan coil units 4a, 4b is under the thermo-on operation, the judgment of step S2 is repeated. If both the fan coil units 4a, 4b are at a stop or under the thermo-off operation, it is judged on the basis of detection signals from sensors provided to the outdoor unit 1 and/or the indoor units 3a, 3b whether the air conditioner is under out-of-gas state or not (step S3).
  • the signal is output from temperature sensors, pressure sensors, etc. provided to the outdoor unit 1 and/or the indoor units 3a, 3b.
  • the signals represent the temperature and pressure at the inlet/outlet ports of the outdoor heat exchanger 13 or the opening degree of the outdoor expansion valve 14 or the like.
  • the signals represent the temperature at the suction ports of the indoor units 3a, 3b, the temperature at the discharge ports of the indoor units 3a, 3b, the pressure at the inlet/outlet ports of the indoor heat exchangers 30a, 30b, or the opening degrees of the indoor expansion valves 31a, 31b.
  • step S5 If the air conditioner is not under the out-of-gas state, the processing returns to step S2 to repeat the judgment as to the driving state of the fan coil units 4a, 4b. If the air conditioner is under the out-of-state, the circulating pump is forcedly driven by the chiller controller 24 (step S4), and the motor-driven expansion valve 21 is opened (step S5).
  • the refrigerant which is condensed and trapped in the refrigerant/water heat exchangers 20a, 20b, etc. is pushed out from the inside of the chiller unit 2 to the liquid pipe 5a or the gas pipe 5c. Therefore, the out-of-gas state can be overcome.
