The specific embodiment

Bottom illustrates one embodiment of the invention with reference to Fig. 1～Fig. 3.

At first with reference to Fig. 1, Fig. 1 is an embodiment skeleton diagram of the formation of expression outdoor unit, its expression: outdoor unit inside is separated into heat exchanger chamber and Machine Room with the dividing plate that extends to vertical direction; In this Machine Room, set compressor of the present invention and refrigerant loop part and the refrigerant piping that is connected these refrigerant loop parts, and in the space that forms by above-mentioned configuration, set a part of part in Denso loop, constitute the Machine Room thus; This outdoor unit also has the last lower clapboard of separating this Machine Room and outdoor control part.For example, external shell 3, the bottom panel 4 by the external shell 2 that covers front and end face, covering side and the back side constituted framework.Be provided with the outlet 10 that heat exchange air has been carried out in discharge in the front of external shell 2, on this outlet 10, be provided with and blow out grid, be used to prevent the outdoor draft fans 20 that barrier is invaded its inboard heat exchanger chamber 7 and infringement is rotated such as stone, prevent to produce and be strayed into finger and wait and accident such as damage.

Handle 12 when the left surface of external shell 3 is provided with this outdoor unit 1 of carrying or carries out installation exercise is provided with breach 13 and distribution mouth 14 on right flank, breach 13 is used to make the tube plate 17 of standing valve 18 to expose; This valve 18 is connected in refrigerant piping the indoor set that is fixed on bottom panel 4; Distribution mouth 14 is terminal boards 29 that the power supply that is used for coming from aforementioned indoor set and communications patching are connected in outdoor control part 9.Establish the opening 15 that atmosphere is led to heat exchanger chamber 7 overleaf.

On bottom panel 4, go up near the pedestal 16 that bottom panel 4 length direction two ends, is provided as the mounting support of this outdoor unit 1 in its lower section towards the direction vertical with this direction; Each part of outdoor control part 9 on the heat exchanger chamber 7, Machine Room 8, its Machine Room 8 of outdoor unit 1 is being set in the above, for supporting them, in margo dexter portion fixing the tube plate 17 of valve 18 is set, this valve 18 be used for refrigerant piping be connected to empty in the unit.

The inside of outdoor unit 1 is divided into heat exchanger chamber 7 and Machine Room 8 by bending to the dividing plate 5 that extends to vertical direction nearly L type, its bend madial wall attaching sound-absorbing material 37; Built-in outdoor draft fan 20, an end are fixed in bottom panel 4 and the other end is hung the outdoor draft fan corner bracket 21 that is used to support outdoor draft fan 20, the outdoor heat converter 19 due to outdoor heat converter 19 in a side heat exchanger chamber 7, and this outdoor draft fan 20, outdoor machine corner bracket 21 and outdoor heat converter 19 mountings sent are on bottom panel 4; In the opposing party's Machine Room 8, compressor 22, accumulator 23, cross valve 24, outdoor motor-driven valve 25, capillary 26 connect with refrigerant piping and are disposed on the bottom panel 4; The reactor 27 of power supply part is fixed in the top of aforementioned separator plate 5 and is built in the Machine Room 8.

On the top of Machine Room 8 lower clapboard 6 is installed, in order to cover the end face of this Machine Room 8; The running control carry out outdoor unit 1 and the outdoor Denso case 28 of communicating by letter with indoor set is set on the lower clapboard 6 on this, is connected terminal board 29, the fuse 31 of power supply from indoor set and communications patching, the connector 30 of relaying distribution of the Machine Room below the lower clapboard 68 on being positioned at, constitute outdoor control part 9 thus.

With reference to Fig. 2 and Fig. 3, Fig. 2 is the figure of Machine Room 8 of outdoor unit 1 of the embodiment of presentation graphs 1; Fig. 3 represents to remove the front external shell of outdoor unit, from the Machine Room seen previously 8 with the figure of outdoor control part 9; With the dividing plate 5 that extends to vertical direction that bends to nearly L type and attach sound-absorbing material 43 in bend inwall side the inside of outdoor unit 1 is separated into heat exchanger chamber 7 and Machine Room 8.According to the present invention, 8 close dividing plate 5 places set compressor 22 in the Machine Room, setting accumulator 23 with respect to the side opposite with dividing plate 5 at this compressor 22 near this compressor ground, is that the center sets other cross valve 24 and motor-driven valve 25 refrigerant loop part such as grade and refrigerant pipings with the inboard by accumulator 23.

Make from the lower position of discharge pipe 33 above this compressor 22 of compressor 22 and turn back,, extend transverse to cross valve 24 lower positions, it is vertically risen making after it vertically descends; In addition, also turn back downwards from the suction line 34 that extend upward accumulator 23 upper ends, and accumulator 23 lower positions with these cylindrical accumulator 23 diameters radius about equally to horizontal bending, after extending to compressor 22 rears it is vertically risen, suction line 34 and discharge pipe 33 are connected on the cross valve 24, thus, discharge pipe 33 is concentrated on compressor 22 rears, suction line 34 also concentrates on around the accumulator 23; Near the dividing plate above the compressor 22 5, guaranteed the space of concentrating, when can set the reactor 27 as a part of part in the Denso loop in this space, establish the sweep that is used to absorb vibration by being provided with in extension from the way of compressor 22 and accumulator 23 extended discharge pipes 33 and suction line 34, restriction is to the cross valve 24 and motor-driven valve 25 refrigerant loop part such as grade and the refrigerant piping transmitting vibrations that are equipped on accumulator 23 inboards.

The discharge pipe 33 that connection is extended from this compressor 22 and accumulator 23 also is fixed on the dividing plate 5 by the fixture 32 with resiliency with the cross valve 24 of suction line 34, but the vibration that self produced to the transmission and the aforementioned cross valve 24 of framework of the vibration of limit compression machine 22 grades thus.

In addition, be located at 8 tops, Machine Room on be provided with on the lower clapboard and be used for relaying is connected to the distribution of compressor 22 in the Machine Room 8 and reactor 27 etc. from outdoor control 9 connector, by being connected, also can put the distribution in the Machine Room 8 thus in order to wherein setting with last lower clapboard 6 near dividing plate 5 then.

Like this, in the present invention, by with mounting in the Machine Room 8 of outdoor unit 1 in the part the heaviest compressor 22 set near dividing plates 5, the position of centre of gravity of outdoor unit 1 is disposed at by middle position as far as possible, when transport operation or installation exercise, the just feasible load homogenising that is added on the

handle

12 and 35 that is located at aforementioned outdoor unit about 1 respectively; In addition, owing to will be equipped on the refrigerant piping part centralized configuration in the Machine Room 8, system separates with the Denso system with refrigerant piping, position assurance below the outdoor control part 9 above the above-mentioned compressor 22 concentrate the space set Denso loop part part, distribution also near dividing plate 5 and last lower clapboard 6, is also put in order distribution.

From the above description, the heaviest compressor is disposed near the dividing plate in the outdoor unit Machine Room, accumulator is equipped on a side opposite of compressor with dividing plate, is that the center sets with other the cross valve and the refrigerant loop part and the refrigerant piping of motor-driven valve etc. with the inboard near aforementioned accumulator, put aforementioned Machine Room inner refrigerant pipe arrangement part in order, the outdoor unit position of centre of gravity can be placed central authorities as far as possible thus, can improve carrying and the operation of installing, owing to can set with Denso system, also can improve the installation and maintenance operation simultaneously with separating refrigerant piping system in the aforementioned Machine Room.
