Explain the operation of the cooling/heating systems that is used for air-conditioner according to the present invention of above-mentioned formation below with reference to Fig. 3 and 6.
At first, describe the situation that air-conditioner moves under refrigerating mode, wherein the flow direction of cold-producing medium is shown in the solid line among the figure.
Compressor 11 refrigerant compressed are carried out heat exchange with the atmosphere that is ventilated by outdoor fan 13a, so that condensation under the two-phase state that gas phase is mixed with liquid phase then by the control supply chamber outer heat-exchanger 13 of cross valve 12.
Condensed refrigerant is supplied with the first muffler 30a under the two-phase state, so that mix equably.Particularly, supply with the cold-producing medium of main body 31 of the first muffler 30a in the diffusion inside of main body 31.At this moment, cold-producing medium flows into the inside of cushion space 34 and antipriming pipe 33 through hole 33a, so the liquid phase that comprises in cold-producing medium can be mixed with its gas phase equably.Then, the mixed uniformly cold-producing medium screen hole type sieve plate 32 of flowing through is so that made gas phase mix with liquid phase more equably before cold-producing medium flows into expansion gear 21.
Expansion gear 21 expands cold-producing medium, and this cold-producing medium mixes with the even of liquid phase by gas phase, and the local pressure reduction of cold-producing medium is eliminated fully.At this moment, the bulbs of pressure are applied on the cold-producing medium equably, and therefore with respect to traditional cooling device of the cold-producing medium expansion that makes inhomogeneous mixing, the mobile noise of cold-producing medium significantly reduces.
Cold-producing medium through expansion gear 21 is supplied with the second muffler 30b once more.Cold-producing medium flows in the main body 31, by antipriming pipe 33, cushion space 34 and sieve plate 32.Because cold-producing medium flows with uniform state, the mobile noise of cold-producing medium is suppressed significantly with respect to the situation that has local pressure reduction.
Cold-producing medium under the uniform state of second muffler 30b discharge is supplied with indoor heat converter 22, and carries out heat exchange with the room air that utilizes indoor fan 22a circulation, so that absorb the surrounding environment heat of air-conditioned room.At this moment, the cooling air emission by indoor heat converter 22 heat exchanges is in air-conditioned room, thus the cooling air-conditioned room.Simultaneously, by discharging refrigerant under uniform state, with respect to cold-producing medium carries out heat exchange under inhomogeneous state conventional apparatus, this can improve evaporation efficiency, thereby improves heat-exchange capacity.
Then, carry out the cold-producing medium of heat exchange by indoor heat converter 22 and supply with compressor 11 once more by acescent 14, above-mentioned circulation repeats, so that cool off air-conditioned room continuously.
In addition, describe the situation that air-conditioner moves now under heating mode, wherein the flow direction of cold-producing medium is represented by the dotted line among the figure.
By the control of cross valve 12, under high temperature and high pressure, supply with indoor heat converter 22 by compressor 11 refrigerant compressed, carry out heat exchange with the room air that ventilates by indoor fan 22a then, thus condensation under the two-phase state that gas mixes with liquid.At this moment, enter in the air-conditioned room by indoor heat converter 22 liberated heat indoor air heated, thus heat rooms.
Then, evenly supplying with expansion gear 21 by the second muffler 30b under the admixture in condensed refrigerant under the two-phase state.The expansion of the cold-producing medium in expansion gear 21 causes cold-producing medium to be converted into the two-phase state or the liquid phase state of low temperature and low pressure.
The cold-producing medium that expands by the expansion gear 21 first muffler 30a that flows through.After cold-producing medium evenly mixes, enter in the outdoor heat converter 13.Cold-producing medium carries out heat exchange with the atmosphere that is ventilated by outdoor fan 13a, so that vaporized refrigerant.Then, the cold-producing medium of evaporation is supplied with compressor 11 once more through acescent 14, and above-mentioned circulation repeats, so that heat air-conditioned room continuously.Under the heating operational mode, the mobile noise of cold-producing medium and expansion noise are suppressed by the first and second muffler 30a and 30b, thereby improve the heat-exchange capacity of air-conditioner, and this and cooling mode of operation are similar.
The cooling/heating systems that is used for air-conditioner according to the present invention has following advantage.
At first,, when cold-producing medium is expanded by expansion gear, can reduce the noise of generation, convert uniform two-phase state to because have cold-producing medium mobile of two-phase state heterogeneous as the sieve plate of noise suppression type filter except filtering function.
The second, because the cold-producing medium that expands by expansion gear utilizes muffler to convert uniform two-phase state to, in refrigerant pipe, eliminated local pressure reduction, thereby prevented to produce the noise that flows by this pressure reduction.
The 3rd, because muffler has the feature of the combination of expansion type silencer and sympathetic response formula silencer, the noise source of different frequency can be eliminated or reduce to this device.
The 4th, eliminated the pressure reduction in the refrigerant pipe, and expansion gear evenly expands cold-producing medium, therefore improve evaporation efficiency, thereby improved the thermal efficiency of air-conditioner.
At last, because muffler is designed to filtering function is combined with noise suppression function, the space that indoor unit occupies can reduce.
For the person of ordinary skill of the art, obviously can carry out different modifications and variations to the present invention.For example, muffler can be arranged on the refrigerant pipe place of outdoor unit and indoor unit.Like this, desire of the present invention covers its all modifications and improvement, as long as they are in the scope and equivalent scope thereof of accompanying Claim book.
