Technical field
The present invention relates to air-conditioning technical field, particularly to a kind of air-conditioning system and operation method thereof.
Background technology
Air-conditioning system be by compressor to refrigerant compress after, make refrigerant carry out heat in indoor and outside
Exchange, thus realize the purpose to indoor temperature regulation.As a example by refrigeration, refrigerant is compressed into by compressor
Outdoor heat exchanger, the gaseous coolant of HTHP liquid in outdoor heat exchanger is sent into after the gaseous state of HTHP
Turn to the liquid refrigerants of cryogenic high pressure, discharge heat to outdoor environment simultaneously, be then depressured through throttling arrangement
After the liquid refrigerants of low-temp low-pressure gasify in indoor heat exchanger the gaseous coolant to low-temp low-pressure, simultaneously
Absorb the heat in indoor environment, eventually pass back to compressor, form a kind of refrigeration cycle.
As can be seen here, air-conditioning system is during properly functioning, and the pressure in each parts is different from,
After air-conditioning system is shut down, provide the most dynamic output of compressor of power for refrigerant circulation, then
In the case of unpowered, the refrigerant in air-conditioning system will spontaneously migrate to the parts of low pressure,
As in cooling mode, refrigerant can be migrated to indoor heat exchanger by outdoor heat exchanger；In a heating mode,
Refrigerant can be migrated to outdoor heat exchanger by indoor heat exchanger, until it reaches isobaric state.Now will go out
Existing refrigerant heat of absorption chamber external environment in outdoor heat exchanger, or to indoor ring in indoor heat exchanger
Border release heat, causes the loss of air-conditioning system energy virtually.
Additionally, after air-conditioning system is again started up, a very long time is needed to set up system pressure difference and cold
Matchmaker's best distribution in systems, causes the refrigerating/heating amount when just starting delayed, it is difficult to meet user fast
The demand of speed refrigerating/heating.

Within protection domain.
The present invention proposes a kind of air-conditioning system.As it is shown in figure 1, this air-conditioning system includes being sequentially communicated to be formed
The compressor 10 of refrigerant circulation circuit, cross valve 20, indoor heat exchanger 30, throttling arrangement 40 and outdoor are changed
Hot device 50.In order to still be able to keep system pressure difference during its running status after air-conditioning system is shut down, at sky
Being additionally provided with the control valve for control piper break-make on the pipeline of adjusting system, specifically, this control valve includes
The first control valve 61 being disposed in the interior on the pipeline between heat exchanger 30 and outdoor heat exchanger 50.Work as air-conditioning
After system is closed (owing to the power source of refrigerant circulation is to be provided by compressor 10, air-conditioning the most herein
System closedown is refered in particular to compressor 10 and is closed), simultaneously close off the first control valve 61.Due to compressor 10 and
One control valve 61 simultaneously closes off, and has blocked the pipeline of circulation between indoor heat exchanger 30 and outdoor heat exchanger 50,
Prevent refrigerant mutually to migrate between indoor heat exchanger 30 and outdoor heat exchanger 50, on the one hand avoid sky
The loss of adjusting system energy；On the other hand the air-conditioning system system pressure difference when running status can be kept,
Upper once start time can set up rapidly system pressure difference and refrigerant best distribution in systems, reach fast
The requirement of speed refrigerating/heating.
In the above-described embodiments, the quantity of this first control valve 61 is preferably two, two first control valves 61
Be separately positioned on indoor heat exchanger 30 and throttling arrangement 40, and throttling arrangement 40 and outdoor heat exchanger 50 it
Between pipeline on.It is further preferred that be disposed in the interior between heat exchanger 30 and throttling arrangement 40 first
Control valve 61 is arranged near indoor heat exchanger 30；It is arranged between throttling arrangement 40 and outdoor heat exchanger 50

The refrigerant that second control valve 62 is possible to prevent in indoor heat exchanger 30 is to compressor 10 or gas-liquid separator 70
Direction migrates；3rd control valve 63 is possible to prevent the refrigerant in outdoor heat exchanger 50 to compressor 10 or gas
Liquid/gas separator 70 direction migrates.It is further preferred that the second control valve 62 sets near indoor heat exchanger 30
Putting, the 3rd control valve 63 is arranged near outdoor heat exchanger 50, and its principle is similar with the first control valve 61,
Do not repeat them here.
Based on above-described embodiment, this air-conditioning system also includes a control device (not shown), and this control fills
Put and be connected with control valve, for controlling the unlatching/closedown of control valve, when air-conditioning system is closed, this control
Device controls control valve and simultaneously closes off with compressor 10.This control device may also include a timer (in figure
Do not show), when air-conditioning system starts, control device and opening control after compressor 10 starts Preset Time
Valve processed, this timer i.e. completes the work of Preset Time timing.Control valve postpones unlatching and is prevented from pressure
The initial stage refrigerant that contracting machine 10 starts flows backwards.
All throttling arrangements 40 that the embodiment of the present invention is mentioned can be capillary, electric expansion valve, throttling
Valve or other parts possessing throttling action or assembly.
The present invention is additionally based upon above-mentioned air-conditioning system and proposes the operation method of a kind of air-conditioning system, and the method is concrete
Including:
Step S10, is receiving user or other equipment after the shutdown command that air-conditioning system sends, simultaneously
Close compressor and control valve；
Step S20, is receiving user or other equipment after the enabled instruction that air-conditioning system sends, is first opening
Open compressor, be then turned on control valve.
In the above-described embodiments, step S20 specifically includes:
Step S21, the enabled instruction that reception user or other equipment send to air-conditioning system；
Step S22, opens compressor according to enabled instruction；
Step S22, postpones opening controlling valve after Preset Time.
