Section.
Referring to Fig. 1, four-way valve 9 is used as switching valve, and four openings can be at following two connected state.
The first: the first opening 91 of four-way valve 9 is connected to the 4th opening 94 of four-way valve 9, the second opening of four-way valve 9
92 are connected to the third of four-way valve 9 opening 93.This situation is suitable for the idle call circulatory system and is in the first operating mode.
Second: the first opening 91 of four-way valve 9 is connected to the second opening 92 of four-way valve 9, the third opening of four-way valve 9
93 are connected to the 4th opening 94 of four-way valve 9.This situation is suitable for the idle call circulatory system and is in the second operating mode.
After four-way valve 9 is arranged, when the idle call circulatory system is in the second operating mode, refrigerant is flowed according to following path:
The refrigerant that compressor 1 comes out flows to four-way valve 9, First Heat Exchanger 2, the heat exchange branch 411 of the first gas-liquid separator 41, second changes
Hot device 3, four-way valve 9, the first gas-liquid separator 41 gas-liquid separation branch 412 selectively, then flow back to compressor 1.
After four-way valve 9 is arranged, when the idle call circulatory system is in the first operating mode, refrigerant is flowed according to following path:
The refrigerant that compressor 1 comes out flows to four-way valve 9, the second heat exchanger 3, the heat exchange branch 411 of the first gas-liquid separator 41, first changes
Hot device 2, four-way valve 9, the first gas-liquid separator 41 gas-liquid separation branch 412 selectively, then flow back to compressor 1.
In one or more embodiments, First Heat Exchanger 2 includes shell and tube exchanger, and/or, the second heat exchanger 3 packet
Include finned heat exchanger.
Full-liquid type case tube heat exchanger has the characteristics that refrigerating capacity is big, Energy Efficiency Ratio is high, so, First Heat Exchanger 2 is used as room
It is preferable using shell and tube exchanger when interior heat exchanger.Above-mentioned technical proposal can utilize its refrigerating capacity using First Heat Exchanger 2
Greatly, the high advantage of Energy Efficiency Ratio.
For using the idle call circulatory system shown in FIG. 1, a specific embodiment is introduced.
Referring to Fig. 3, when refrigeration cycle: refrigerant subsequently flows to the first gas-liquid separator in the shell fluid flow of First Heat Exchanger 2
41 heat exchange branch 411, the second heat exchanger 3.Then there are two types of selectable circulation styles: mode one is to flow directly into the second gas
Liquid/gas separator 42；Mode two is the gas-liquid separation branch 412 for first flowing to the first gas-liquid separator 41, then flows to the second gas-liquid point
From device 42.In aforesaid way one, refrigerant only carries out gas-liquid separation (referred to as strategy one) by the second gas-liquid separator 42.Above-mentioned side
In formula two, refrigerant all carries out gas-liquid separation (referred to as strategy two) by the first gas-liquid separator 41 and the second gas-liquid separator 42.
The refrigerant for flowing back to compressor 1 is compressed by compressor 1, and compressed high pressure gas enters first through high-pressure exhaust pipe
Heat exchanger 2 is condensed into high-temperature liquid state refrigerant, and the heat of releasing is pulled away.Then pass through the first gas-liquid separator 41, with evaporator
The low temperature liquid refrigerant of outlet exchanges heat in gas-liquid separator, reduces the temperature (promoting degree of supercooling) of high-temperature liquid state refrigerant,
Cryogenic gaseous refrigerant temperature (promoting the degree of superheat) is promoted simultaneously.High-temperature liquid state refrigerant after heat exchange passes through after coming out from gas-liquid separator
Electric expansion valve throttling is crossed, becomes low-pressure liquid refrigerant, enters back into the second heat exchanger 3, complete the circulation of refrigerant.In the case of this
One valve 5 is opened, and the second valve 6 is closed.
Seldom had under high-temperature condition band liquid situation, for solve worst hot case under unit harmful degree of superheat, it is implementable such as
Lower operation.Refrigerant absorbs the heat of the refrigerating medium in tube side in the shell fluid flow of the second heat exchanger 3, and constantly evaporates.When arriving
Up to gas is become when the outlet of the second heat exchanger 3, the first valve 5 is closed, and the second valve 6 is opened, and refrigerant is without the first gas-liquid separator
41, only pass through the second gas-liquid separator 42,1 entrance of compressor is entered after gas-liquid separation, completes gas-liquid separation and enter the pressure of compressor 1
Contracting.Enter First Heat Exchanger 2 through high-pressure exhaust pipe by the compressed high pressure gas of compressor 1 and be condensed into high-temperature liquid state refrigerant,
The heat of releasing is pulled away.Then pass through the first gas-liquid separator 41, from gas-liquid separator come out after by electric expansion valve section
Stream, becomes low-pressure liquid refrigerant, enters back into the second heat exchanger 3, complete the circulation of refrigerant.
In refrigeration cycle, gas-liquid separation can be carried out using several gas-liquid separators using corresponding policy control.Also
Above-mentioned two strategy can be used at times.Above-mentioned technical proposal realizes the heat-exchange capacity for controlling refrigerant more flexiblely, makes
Unit performance is obtained to greatly improve.
The principle of defrost circulation and refrigeration cycle is essentially identical.When unit defrost, above-mentioned technical proposal is by using two
A gas-liquid separator only carries out gas-liquid separation by the second gas-liquid separator 42.By gas-liquid separator twice, two are carried out
Grade gas-liquid separation, can greatly reduce liquid hammer possibility, extend the service life of compressor 1 and the reliability of unit.
When set heat exchange amount is enough, control refrigerant only by 42 gas-liquid separation of the second gas-liquid separator, avoids transition heat exchange bring
Problem.
Referring to fig. 2, when heating circulation: 93 conducting of the second opening 92 and third opening of four-way valve 9, the first of four-way valve 9
94 conducting of opening 91 and the 4th opening.Refrigerant is introduced into the of the second heat exchanger 3 after the outflow of the refrigerant exit 12 of compressor 1
Two openings 32, then from 31 outflow of the first opening of the second heat exchanger 3.Enter the first gas-liquid separation after electric expansion valve 7
The heat exchange branch 411 of device 41.After the heat exchange outflow of branch 411, the second opening 22 of First Heat Exchanger 2 is entered, is changed from first
The second opening 92, the third opening 93 of four-way valve 9 are reached after 21 outflow of the first opening of hot device 2.Then there are two types of circulation styles.
First way is, without the gas-liquid separation branch 412 of the first gas-liquid separator 41, is directly open from the third of four-way valve 9
93 flow to the second gas-liquid separator 42, then flow to the refrigerant inlet 11 of compressor 1.The second way are as follows: the third of four-way valve 9
The refrigerant of 93 outflow of opening is flowed into the gas-liquid separation branch 412 of the first gas-liquid separator 41, then flows to the second gas-liquid separation
Device 42 is finally flow back into compressor 1.
