The operation of above-mentioned air regulator is as follows.During refrigerating operation (solid arrow in Fig. 1), in refrigerant pipe
The refrigerant stream into compressor unit 32 at part connector 47 by four-way valve 39 and is introduced into collector 38.Work as warp
When crossing collector, associated liquid refrigerant is detached with gaseous refrigerant and liquid refrigerant is temporarily stored at collector
In 38.
Then, gaseous refrigerant is introduced into compressor 37 and is compressed.Compressed refrigerant is via the first refrigeration
Agent conduit coupling 42,35 and refrigerant pipe fitting 71 are introduced into heat exchanger of heat source unit 31.Refrigerant, which passes through, has heat source
The heat exchanger 5 of the plate 6,7 of heat exchanger unit 31, thus refrigerant generation condense (heat exchanger 5 is used as condenser).Cause
This, heat is passed to the extraneous air of the heat exchanger element 6,7 parallel across heat exchanger 5.Expansion valve 33 is opened completely, with
Cooling period is avoided to have high pressure drop.Then, refrigerant is flowed via third refrigerant pipe connecting component 34,43 and refrigerant pipe fitting
Enter in compressor unit 32.In compressor unit 32, refrigerant pipe fitting 52 is flowed through to refriger-ant section, and then flows through secondary cooling
Expansion valve 41 and secondary cooling heat exchanger 40, partially flow through the refrigerant pipe introduced via third refrigerant pipe connecting component 46
Part 49, refrigerant pipe fitting and third refrigerant connector 54, get in unit 50.Then, refrigerant is by indoor expansion valve 56
Further expansion, the evaporation in heat exchanger 53 (heat exchanger 53 is used as evaporator), to cooling space 72 to be regulated.Cause
This, heat is transmitted to the refrigerant for flowing through heat exchanger 53 from the air in space to be regulated.While cooling, secondary cooling heat exchanger
40 main purpose is to carry out secondary cooling to flowing to the liquid refrigerant of indoor unit 50 by refrigerant pipe fitting 49.Finally, then
It is secondary that refrigerant is introduced into compressor unit 32 via the 4th refrigerant pipe connecting component 55,47 and refrigerant pipe fitting.
It is well known that the performance of indoor air regulator is equal to the product of enthalpy stream and quality stream.Therefore, when enthalpy stream increases
When, reduced quality stream can be used.The cooling heat exchanger of pair is for increasing indoor enthalpy stream.Therefore, performance can not damaged
In the case of, reduce quality stream.As a result, the pressure drop in liquid line can be reduced so that compressor 37 needs the work transmitted to reduce,
To improve the efficiency of whole system.
During heating, which is reversed, wherein shows to heat with the dotted arrow in Fig. 1.This process is in original
It is identical in reason.However, during heating, first heat exchanger 5 is used as evaporator, and second heat exchanger 53 is used as condensation
Device.Particularly, refrigerant is introduced into via the first refrigerant pipe connecting component 42 in compressor unit 32, is flowed via four-way valve 39
Enter in collector 38, then compressed in compressor 37, flowed into four-way valve 39 later and passes through the 4th refrigerant pipe fitting
Connector 47,55 and refrigerant pipe fitting, 50 (specifically, the indoor heat exchanger of indoor unit being condensed into wherein refrigerant
53) (indoor heat exchanger 53 is used as condenser).Then, refrigerant inflated valve 56 expands, then via third refrigerant pipe
Part interconnection piece 54,46 is introduced again into, and into compressor unit 32, in compressor unit 32, refrigerant flows into pipe fitting 49
In and by secondary cooling heat exchanger 40.
By carrying out refrigerant injection after the evaporator, the sucking overheat before compressor can be optimized.As a result, can be with
Discharge temperature is reduced, brings system effectiveness more preferable therewith and service life extended advantageous effect.When heated, secondary cooling heat exchanger
40 for improving at the suction port of compressor via the refrigerant pipe fitting 52 being connect with the refrigerant pipe fitting 51 of 37 upstream of compressor

Two phase refrigerant evaporation in refrigerant pipe fitting 49.
Then, the part in refrigerant flows into refrigerant pipe fitting 52, expands and flows through in pair cooling expansion valve 41
The cooling heat exchanger 40 of pair, is introduced again into the refrigerant pipe fitting 51 of 38 upstream of collector, later thus to flowing through by pair
The refrigerant of the refrigerant pipe fitting 49 of cooling heat exchanger 40 is precooled.Remainder is connected via second refrigerant pipe fitting
Part 43,34 and refrigerant pipe fitting flow into heat exchanger of heat source unit 31.Refrigerant is by the master in heat exchanger of heat source unit 31
Expansion valve 33 further expands, then the evaporation in heat exchanger 5 (heat exchanger 5 is used as evaporator), later via the first refrigeration
Agent pipe connecting component 35 and 42 and refrigerant pipe fitting be reintroduced into compressor unit 32.
Because of the separation of compressor unit 32 and heat exchanger of heat source unit 31, compressor unit 32 may be mounted to that
To in the region of insensitive for noise so that both made setting indoors, noise jamming will not be caused because of compressor.In addition, can
The shell 44 of compressor unit 32 is well isolated from using sound insulation.In addition, due to the heat that can be passed in space to be regulated
Separation design between source heat exchanger unit 31 and compressor unit 32, leads to the air for flowing through heat exchanger of heat source unit 31
In there is no compressor noise.
Because the Unit Weight of heat exchanger of heat source unit 31 and compressor unit 32 is lighter, installation is improved.
In addition, compressor unit 32 may be mounted to that on floor so that heavy-duty comprssor unit need not be promoted.Because of compressor unit
32 area occupied (width and depth) is relatively small and compressor unit 32 be especially its shell height it is relatively low, so pressure
Contracting machine unit 32 can be even hidden when being disposed in room to be regulated, such as in cabinet or under-counter.
Heat exchanger of heat source unit 31 also has the advantages that do not have noise jamming.Because in heat exchanger of heat source unit 31 not
Including compressor, so the noise that unique sound in the gas flow is fan can be carried secretly, to which the noise in air-flow strongly reduces.
In addition, shell 2 can be completely enclosed, become space 72 to be regulated so that no sound is passed in space.In addition, can profit
The shell is well isolated from sound insulating member.Because the height of heat exchanger of heat source unit 31 is relatively low, it is easy unit being hidden in
Such as in ceiling.Therefore, unit 31 is invisible from outside.Compared with the unit with compressor in same housing,
Because the height of heat exchanger of heat source unit 31 is relatively low, installation is also improved.Particularly, lower height is to use
The heat exchanger 5 of " V " shape shape is enable to efficiently as auxiliary and height is relatively low.
Because the especially secondary cooling heat exchanger of secondary cooling unit is integrated into compressor unit rather than heat exchanger of heat source
In unit, so the long gaseous refrigerant pipeline that the suction side of heat exchanger of heat source and compressor connects can be compressed machine
The shorter tube line 52 for including in unit replaces.It is therefore possible to shorten making the major diameter pipeline needed for gaseous refrigerant flowing.In other words
It says, it can be by the cooling heat exchanger of pair being placed in compressor unit and cyclization connection passes through heat exchanger of heat source module
Compressor unit and the refrigerant pipe fitting of indoor unit connection are attached between heat exchanger of heat source unit and indoor unit to avoid
Add route.
If the cooling heat exchanger of pair is arranged in heat exchanger of heat source module and the fluid between unit 31 and 50 connects
The shell 44 by compressor unit 32 will not be surround but be directly connected to by connecing, then third heat exchanger of heat source must compress
Have at machine unit 32 by compressor unit 32 and the connection of heat exchanger of heat source unit 31 to realize the extension wire of pipeline 52.Cause
This, compared with this situation, present embodiment is improved, bringing the result is that installation is simpler and installation cost is lower.
In addition, because main expansion valve 33 is arranged in heat exchanger of heat source unit 31, can compensate for by compressor unit
Refrigerant pressure drop caused by relatively long refrigerant pipe fitting between 32 and heat exchanger of heat source unit 31 and two-phase flow noise can
It is decreased at least to a certain degree.
