The embodiment of air-conditioning of the present utility model is described referring to Fig. 1.
Air-conditioning in the present embodiment is multi-gang air-conditioner, and it has two indoor sets be arranged in parallel.Air-conditioning comprises two heat-exchange systems, one is the first conventional heat-exchange system, comprise the first compressor 2, oil eliminator 15, cross valve 3, outdoor heat exchanger 4, outdoor electrical expansion valve 5, two indoor heat exchangers be arranged in parallel 6 and gas-liquid separator 9, each indoor heat exchanger 6 correspondence arranges an indoor electronic expansion valve 7, its annexation is identical with existing air-conditioning, does not repeat them here.Another one is the second heat-exchange system, the air intake duct that the first refrigerant that part flows through pipeline between outdoor heat exchanger 4 and indoor heat exchanger 6 is directly introduced the first compressor 2 by a refrigerant branch road 8 is set, the heat that the second heat-exchange system Absorbable rod air-conditioning internal heat generation parts distribute the first refrigerant passed to by the heat of absorption in refrigerant branch road 8.
In the present embodiment, refrigerant branch road 8 accesses on the pipeline between outdoor heat exchanger 4 and outdoor electrical expansion valve 5, certainly, also on accessible pipeline between outdoor electrical expansion valve 5 and indoor heat exchanger 6.
Further, refrigerant branch road 8 being provided with branch road electric expansion valve 10 and branch road heat exchanging part 121, controlling by regulating the aperture of branch road electric expansion valve 10 amount directly introducing the first refrigerant in the first compressor 2 air intake duct.Also can arrange controller, controller regulates the aperture of branch road electric expansion valve 10 according to the mode of operation of the first heat-exchange system.Controller can be arranged separately, also can be the master controller of air-conditioning.The exchange of heat is carried out by branch road heat exchanging part 121.
As a kind of preferred embodiment, the second heat-exchange system comprises the closed circuit of the second refrigerant, absorbs the heat that electrical appliance kit 1 distributes and the first refrigerant passed to by the heat of absorption in refrigerant branch road 8 by second refrigerant that circulates.Concrete, the second refrigerant circulation circuit is provided with the second compressor 11, first heat exchanging part 122, heat-exchanging electronic expansion valve 13 and the second heat exchanging part 141.Air-conditioning internal heat generation parts can but to be not limited to be the electrical appliance kit 1 of air-conditioning.
Specifically Each part is introduced for electrical appliance kit 1 in this enforcement.Second heat exchanging part 141 is arranged at electrical appliance kit 1 place, for the heat utilizing the second refrigerant absorption electrical appliance kit 1 to distribute.First heat exchanging part 122 is arranged at branch road heat exchanging part 121 place of refrigerant branch road 8, and the heat for being absorbed by the second refrigerant passes to the first refrigerant in refrigerant branch road 8.The first heat-exchanger rig 12 is formed by branch road heat exchanging part 121 and the first heat exchanging part 122, the radiator 142 of the second heat exchanging part 141 and electrical appliance kit 1 forms the second heat-exchanger rig 14, second heat exchanging part 141 one end connects heat-exchanging electronic expansion valve 13, and the other end connects the air entry of the second compressor 11.
For above-mentioned air-conditioning, additionally provide the control method of air-conditioning.
When the first heat-exchange system running refrigerating pattern, environment temperature is all generally worst hot case, and multi-connected machine is all adopt frequency conversion drive, caloric value is relatively large, the general caloric value that can reach a few hectowatt, now branch road electric expansion valve 10 is opened, and allow part after branch road electric expansion valve 10 throttling, become low pressure refrigerant through the first refrigerant of condensation and enter the first heat-exchanger rig 12, and the second refrigerant compressed through the second compressor 11 in the second heat-exchange system also enters the first heat-exchanger rig 12.In the first heat-exchanger rig 12, the first refrigerant in branch road heat exchanging part 121 absorbs the heat of the second refrigerant release in the first heat exchanging part 122, the first refrigerant being heated into gaseous state is drained into the air intake duct of the first compressor 2, increase the suction superheat of the first compressor 2, the suction side being conducive to guarantee first heat-exchange system is like this gaseous coolant, that avoids the first compressor 2 returns liquid hidden danger, increases the reliability of system.Second refrigerant after release heat, enters the second heat-exchanger rig 14 in the first heat-exchanger rig 12 after heat-exchanging electronic expansion valve 13 throttling, and at the second heat-exchanger rig place, the second refrigerant absorbs the heat that electrical appliance kit 1 distributes, and reaches the object of cooling electrical appliance kit 1.According to the electric operation situation of electrical appliance kit 1, the adjustment of heat-exchanging electronic expansion valve 13 aperture can be carried out, thus reaches the object of controlled cooling model effect simultaneously.
In like manner, when the first heat-exchange system runs heating mode, the outdoor heat exchanger 4 of the first heat-exchange system is in evaporation side, need to meet from environment temperature absorption heat to heat requirement, but now environment temperature is lower, first heat-exchange system exchange capability of heat is poor, controlling brancher electric expansion valve 10 is opened greatly, allow the first refrigerant of part low-temp low-pressure in the first heat-exchanger rig 12, absorb the heat of high temperature of the second refrigerant release, significantly can improve heat transfer boundary condition, increase heat transfer effect, reach the object of cooling electrical appliance kit 1, simultaneously, part first refrigerant is directly conducting to the low pressure air suction side of the first compressor 2, improvement system cold medium flux and overheat condition.
When the first heat-exchange system runs defrost pattern, the outdoor heat exchanger 4 of the first heat-exchange system is in condensing state, but exist owing to now there being frost, system condensing pressure and condensation temperature are all in a lower state, cooled liquid first refrigerant is after branch road electric expansion valve 10 throttling, enter in the first heat-exchanger rig 12, heat is absorbed from the condensation side of the second heat-exchange system, become the low-pressure side that gaseous coolant enters the first compressor 2, participate in again in defrost through the first compressor 2, the heat that the electrical appliance kit 1 that second heat-exchange system absorbs distributes is for the defrost of the first heat-exchange system, simultaneity factor stream is shorter, not exclusively pusher side absorbs heat indoor, the defrost of the first heat-exchange system can be accelerated, improve the comfort of user.
Wherein, the concrete structure of the first heat-exchanger rig 12 is not limit, the structure of heat exchange between branch road heat exchanging part 121 and the first heat exchanging part 122 can be realized, such as branch road heat exchanging part 121 and the first heat exchanging part 122 are heat exchanger tube, or the first heat exchanging part 122 is the space in a housing, branch road heat exchanging part 121 is heat exchanger tube in housing etc.
The concrete structure of the second heat-exchanger rig 14 is not also limit, and can realize the structure of heat exchange between the second heat exchanging part 141 and radiator 142.As a kind of preferred embodiment, radiator 142 is gilled radiator, and the second heat exchanging part 141 in coil-like, and is arranged in the fin of radiator 142.
Certainly, be understandable that, the first heat-exchanger rig 12 and the second heat-exchanger rig are all not limited to said structure, as long as can realize the structure that between the first refrigerant and the second refrigerant, heat transmits.It is multi-connected machine that air-conditioning is also not limited to, even multi-connected machine, the quantity of indoor set is also not limited to two.First refrigerant and the second refrigerant can be the same or different.
