Adjust refrigerator all-in-one operationally, compressor the coolant flowed out temperature after vaporizer is relatively low, due to air conditioning box body and
Connecting pipe is offered, so that the relatively low coolant part of this temperature flows to air-conditioning so that Indoor Temperature between refrigerator box body
Spend the higher air coolant relatively low with temperature carry out heat exchange reduce indoor air themperature, another part flows to refrigerator
Refrigerator is freezed, thus realizes air-conditioning and refrigerator can share a set of blood circulation, save system cost.But,
Owing to the coolant that temperature is relatively low is divided into two parts, a part flows to air-conditioning and another part flows to refrigerator, so makes to have leisure
The refrigeration adjusted is less desirable.And this programme is when the first indoor set runs heating mode, the coolant that temperature is higher
Being realized the intensification of room air by heat release, and the refrigerant temperature after heat release is relatively low, the first indoor control module is according to temperature
Temperature in the refrigerator of degree detection module detection controls the first electric expansion valve unlatching with the pre-set target temperature of refrigerator, comes
The coolant making temperature relatively low enters into and realizes the cooling to refrigerator in refrigerator, thus avoids when indoor set heats mould in operation
Under formula, the coolant energy of this part can only be discharged in air waste energy resource, it is achieved that the first indoor set is in system
The energy regenerating of the coolant under heat pattern, improves energy utilization rate.What in this programme, refrigerator utilized is that air-conditioning is to room
After inside heating, in the energy input should being discharged in air to refrigerator itself, thus realize the recovery to energy.
Compared in prior art, the heating effect that this programme will not make air-conditioning itself realize declines.

Temperature in cabinet, according to the pre-set target temperature of the temperature in refrigerator Yu refrigerator control the unlatching of the first electric expansion valve with
Close.When the first indoor set runs heating mode, the coolant that temperature is higher realizes the intensification of room air by heat release, passes through
Refrigerant temperature after heat release is relatively low, and the temperature in the refrigerator that the first indoor control module detects according to temperature detecting module is with cold
The pre-set target temperature hiding cabinet controls the first electric expansion valve unlatching, and the coolant making temperature relatively low enters in refrigerator and realizes
Cooling to refrigerator, thus avoid, when indoor set is under running heating mode, can only being discharged to greatly by the coolant energy of this part
Gas is wasted energy resource, it is achieved that the energy regenerating of the coolant that the first indoor set is in a heating mode, improves energy
Source utilization rate；On the other hand, after the coolant that temperature is relatively low enters in refrigerator the cooling that heat absorption realizes refrigerator, this is cold
Matchmaker is raised by endothermic temperature and enters in compressor, compared to existing technology in refrigerant temperature after heat release is relatively low directly enters
Enter in compressor, reduce the power consumption of compressor, thus extend the life-span of compressor.
The above, above example only in order to the technical scheme of the application to be described, is not intended to limit；Although with reference to front
State embodiment the application has been described in detail, it will be understood by those within the art that: it still can be to front
State the technical scheme described in each embodiment to modify, or wherein portion of techniques feature is carried out equivalent；And these
Amendment or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of the application each embodiment technical scheme.
