When difference reaches setting range, third control valve 3 and the 4th control valve 4 can be adjusted, third control valve 3 is made to open c/d,
4th control valve, 4 standard-sized sheet, refrigerant largely flows to refrigerator at this time, and small part flows to indoor heat exchanger 30, so that refrigerator and air conditioner one
Body machine preferentially freezes to refrigerator, since room temperature has been adjusted in place substantially at this time, even if keeping refrigerant most of
Flow to refrigerator, it is also ensured that room temperature is maintained within the scope of set temperature, and user is made to obtain suitable room temperature.
Since cold regulation herein is realized by control cold medium flux size, the bulk flow of refrigerant is not sent out
It is raw to change, therefore the refrigeration needs of indoor heat exchanger 30 and refrigerator can be met always.This be utilized structurally reasonablely refrigerator and
The design feature of air-conditioning provides refrigerating capacity to refrigerator and indoor heat exchanger 30 simultaneously using the outdoor heat exchanger 20 of air-conditioning, effectively
Ground realizes having complementary functions for air-conditioning and refrigerator, reduces equipment investment, reduces equipment cost, improves air-conditioning refrigerator one
The overall operation efficiency of machine, so that the operational efficiency of air-conditioning refrigerator all-in-one machine is higher, energy distribution is more reasonable.A/b herein
Numerical value with c/d is less than 1, can specifically be adjusted according to the actual situation.
Controlling the first control valve 1, the second control valve 2, the 4th control valve 4 and 6 standard-sized sheet of the 6th control valve, third control valve
After the step of 3 open c/d, control the 5th control valve 5 and the closing of the 7th control valve 7, progress control method further include: obtain cold
Freeze the temperature in area 412 and chill space 411；When the temperature of freeze space 412 and chill space 411 reaches set temperature, control first
Control valve, the second control valve, third control valve, the 4th control valve 4 and 6 standard-sized sheet of the 6th control valve control the 5th control valve 5 and the
Seven control valves 7 are closed, and are made outdoor heat exchanger 20, indoor heat exchanger 30 and refrigerator while being opened, and the first by-passing valve and second is controlled
By-passing valve is closed, and 10 low-frequency operation of compressor is controlled.
When the temperature of freeze space 412 and chill space 411 reaches set temperature, since room temperature before is basic
On be adjusted in place, the temperature of refrigerator inside freeze space 412 and chill space 411 at this time also it is adjusted in place, therefore only need compared with
Few refrigerating capacity is just able to maintain that current room temperature and freeze space 412 and 411 temperature of chill space, can control pressure at this time
10 low-frequency operation of contracting machine reduces the energy consumption of compressor 10.The integrally cooling amount as needed for indoor heat exchanger 30 and refrigerator reduces,
Even if therefore compressor 10 frequency reduce, room temperature and freeze space 412 and 411 temperature of chill space will not be caused compared with
It is big to influence, it still can guarantee that room temperature and freeze space 412 and 411 temperature of chill space maintain target temperature range, mention
The operational energy efficiency of high air-conditioning refrigerator integrated machine reduces its energy charge, saves the energy.
Progress control method further include: as temperature deviation pn >=T1, control the first control valve 1, the second control valve, third
6 standard-sized sheet of control valve and the 6th control valve, the 4th control valve 4 of control open a/b, control the 5th control valve 5 and the 7th control valve 7 closes
It closes, make outdoor heat exchanger 20, indoor heat exchanger 30 and refrigerator while opening, control the first by-passing valve and the second by-passing valve is closed,
Control the operation of 10 high frequency of compressor.
After air-conditioning refrigerator all-in-one machine is switched on operation a period of time, if temperature deviation is still not up to setting range,
Illustrate that room temperature is not still adjusted in place, need to continue temperature in all one's effort quickly-conditioning indoor, therefore is cold there is still a need for making at this time
Matchmaker is most of to be flowed to indoor heat exchanger 30, can continue that the 4th control valve 4 is kept to open a/b, thus to the flow of refrigerant into
Row regulation.After room temperature is adjusted in place, so that it may continue to control each control valve according to above-mentioned control strategy,
It can be adjusted in place to make room temperature and ice the temperature inside the box.
Progress control method further include: when air-conditioning refrigerator all-in-one machine heating operation, control the first control valve the 1, the 4th control
Valve 4, the 5th control valve 5 and the 7th control valve 7 processed are opened, and the second control valve 2, third control valve 3, the 6th control valve 6 are closed, control
It makes the first by-passing valve and the second by-passing valve is closed, control outdoor heat exchanger 20 is closed, and it controls indoor heat exchanger 30 and refrigerator is opened,
Control the operation of 10 high frequency of compressor.
In the above-described embodiments, when 40 all-in-one machine heating operation of air-conditioning refrigerator, by controlling the first control valve the 1, the 4th
Control valve 4, the 5th control valve 5 and the 7th control valve are opened, and the second control valve 2, third control valve 3, the 6th control valve 6 are closed,
Room conditioning, refrigerator 40 and compressor 10 can be enabled to form a complete circuit, in the circuit, when refrigerant flows through air-conditioning
Heat release is condensed, thus achieve the purpose that air-conditioning heating, evaporation endothermic when flowing through refrigerator 40, to reach the mesh of the refrigeration of refrigerator 40
, while 10 high frequency of compressor is run, and is facilitated air-conditioning and is quickly met heating needs, refrigerator 40 quickly meets refrigeration demand.
Optionally, in the above-described embodiments, further includes: whether detection 40 freeze space 412 of refrigerator and chill space 411 reach and set
Determine the temperature deviation between temperature, or detection indoor environment temperature and set temperature；When 40 freeze space 412 of refrigerator and chill space
411 reach set temperatures or when temperature deviation pn < T2, the first control valve 1 of control, the 4th control valve 4, the 5th control valve 5 and the
Seven control valves 7 are opened, and the second control valve 2 of control, third control valve 3 and the 6th control valve 6 are closed, and control refrigerator 40 and interior is changed
Hot device 30 is opened, control 10 intermediate frequency of compressor operation.
When 40 freeze space 412 of refrigerator and chill space 411 reach set temperature, illustrate current 40 refrigeration demand of refrigerator compared with
Low, 10 intermediate frequency of compressor runs the refrigeration demand that just can satisfy refrigerator 40.As temperature deviation pn < T2, illustrate current room
Temperature deviation is smaller between interior environment temperature and set temperature, and the heating needs of air-conditioning are lower, and 10 intermediate frequency of compressor runs energy
Enough meet the heating needs of air-conditioning, additionally it is possible to achieve the effect that save resource.
Optionally, in the above-described embodiments, when 40 freeze space 412 of refrigerator and chill space 411 reach set temperature and temperature
