  • a direction of the refrigerant flow in the intake tubes 11 and 18, the exhaust tube 12, the indoor connecting tube 13, and the outdoor connecting tube 14 are controlled by the four-way valve 7. That is, when the exhaust tube 12 is connected to the outdoor connecting tube 14 and the intake tubes 11 and 18 are connected to the outdoor connecting tube 13, the system is operated as a cooling mode. When the exhaust tube 12 is connected to the indoor connecting tube 13 and the intake tubes 11 and 18 are connected to the outdoor connecting tube 14, the system is operated as a heating mode.
  • the service valve 15 functions to form vacuum in a tube, temporarily stop the system operation, and inject and exhaust the refrigerant.
  • the service valve 15 is projected out of the outdoor unit case 10.
  • a liquid-to-suction heat exchanger 8 for eliminating moisture from the refrigerant introduced into the compressor 1 is disposed on a passage of the intake tube 11.
  • the intake tube 18 is disposed on an upstream side of the heat exchanger 8 while the intake tube 11 is disposed on a downstream side thereof.
  • the liquid-to-suction heat exchanger 8 is vertically disposed to simplify the structure of the outdoor unit and reduce the vibration.
  • the exhaust portion of the outdoor heat exchanger 2 is provided with an exhaust pipe connected to the indoor unit by the service valve 22.
  • the exhaust pipe of the outdoor heat exchanger 2 is provided with a dryer 5 for preventing the pipe from corroding by moisture removed from the refrigerant used for the heat exchange and an linear expansion valve 6 for expanding the refrigerant used for the heat exchange.
  • the dryer 5 and the linear expansion valve 6 are vertically disposed to minimize the outdoor unit and attenuate the vibration.
  • an arrangement of the dryer 5, the linear expansion valve 6 and the liquid-to-suction heat exchanger 8 is improved to make the outdoor unit compact.
  • Fig. 2 shows an internal structure of the apparatus room depicted in Fig. 1.
  • FIG. 2 there are shown the compressor 1, the liquid-to-suction heat exchanger 8, the dryer 5, and the linear expansion valve 6.
  • the liquid-to-suction heat exchanger 8 is vertically disposed to make the internal structure of the apparatus room compact.
  • the dryer 5 and the linear expansion valve 6 are vertically arranged along a common vertical line, thereby further making the internal structure of the apparatus room compact and reducing the vibration.
  • a first indoor passage 23 is provided to direct the refrigerant exhausted from the outdoor heat exchanger 2 to a lower portion of the dryer 5.
  • the linear expansion valve 6 is disposed above the dryer 5 along the common vertical line.
  • a second indoor passage 16 is provided to connect an exhaust portion of the linear expansion valve 6 to the liquid -to-suction heat exchanger 8.
  • a third indoor passage 16 is provided to exhaust the refrigerant directed into the liqui d-to-suction heat exchanger. The refrigerant is directed to the service valve 22, successively flowing along the indoor passages 23, 16 and 17
  • the refrigerant exhausted from the four -way valve 7 is directed into the liquid-to-suction heat exchanger 8 through the first intake tube 18, used for the heat -exchange in the liquid-to-suction heat exchanger 8, and then directed into the compressor 1 through the second intake tube 11.
  • the liquid-to-suction heat exchanger 8, the dryer 5 and the expansion valve 6 are vertically arranged in parallel with each other.
  • Fig. 3 shows the liquid-to-suction heat exchanger in more detail.
  • the liquid-to-suction heat exchanger 8 comprises an outer tube 21 along which the refrigerant used for the heat-exchange and exhausted from the outdoor heat exchanger 2 flows and an inner tube 25 along which the refrigerant is directed to the compressor 1. That is, the inner tube 25 is connected either the first intake tube 18 or the second intake tube 11 to allow the low pressure/low temperature refrigerant to flow.
  • the outer tube 21 is connected to the second indoor passage 16. In this state, since gas flowing along the inner tube 25 is subject to heat from the refrigerant of the outer tube 21, no liquid is remained in the gaseous refrigerant flowing along the inner tube 25. In addition, the refrigerant flowing along the inner and outer tubes 25 and 21 flows in an opposite direction to each other as indicated by an arrow, thereby further improving the heat exchange efficiency.
  • Fig. 4 is a plane view of the internal structure of the apparatus room.
  • a disposition angle between the elements is limited in a predetermined range.
  • the disposition angle ⁇ means an angle between a first imaginary line linearly extending toward the second intake tube 11 and a second imaginary line linearly extending toward the linear expansion valve b and the dryer 5.
  • the disposition angle ⁇ is limited in a range of 15-90°. The reason for limiting the disposition angle ⁇ to such a range will be described hereinafter.
  • the pipes arranged around the compressor 1 may be vibrated. Therefore, in order to prevent the vibration, it is preferable that an angle between a horizontal extending line of the second intake tube 11 and the central point B of the compressor 1 is less than 90°. As a length of the intake tube 11 is increased, the more vibration is applied to the intake tube 11. Particularly, since the rigidity of the intake tube 11 is high and disposed close to the compressor, the intake tube 11 is applied with the higher vibration.
  • the disposition angle ⁇ (15-90°) proposed above reduces the vibration applied to the second intake tube 11 and makes the apparatus room compact.
  • the disposition angle ⁇ is less than 15°, there may be an interference between the elements (components). That is, when the vibration is generated by the compressor 1, the elements may collide with each other, thereby generating noise.
  • the disposition angle ⁇ is greater than 90°, since the distance from the linear expansion valve 6 and the dryer 5 from the liquid-to-suction heat exchanger 8 is too far, the vibration of the intake tubes 11 and 18 may be magnified through the second and third indoor passages 16 and 17, making it difficult to make the apparatus room compact.
  • the dryer 5 is vertically connected to the linear expansion valve 6 to make the apparatus room compact.
  • the liquid-to-suction heat exchanger 8 is also vertically disposed.
  • Fig. 5 shows a graph illustrating a compact rate of the outdoor unit with the elements arranged with the above-proposed disposition angle.
  • an X-axis indicates a disposition angle while a Y-axis indicates a compact rate of the outdoor unit.
  • the graph shows a comparison of a component mounting space of the apparatus room to an amount of the component mounting space and a non-mounting space.
  • the compact rate is steeply varied based on critical angles 15° and 90°.
  • the above-described arrangement of the present invention can be applied to an outdoor unit of a cooling -only air conditioning system, an outdoor unit of a multi -type air conditioning system, and an outdoor unit of an accumulator type air conditioning system as well as the outdoor unit of the cooling-heating type air conditioning system.
  • the dryer 5 may be omitted. Even in this case, the disposition angle proposed by the present invention is identically applied.
  • an outdoor unit with a four-way valve is exampled as an embodiment of the present invention, the concept of the present invention can be identically applied to the outdoor unit without the four-way valve.
  • the apparatus room can be designed in the more compact structure, an overall size of the outdoor unit can be minimized, saving the manufacturing costs and time.
  • the vibration generated in the apparatus room of the outdoor unit can be effectively attenuated.
