Description
Technical field
The utility model relates to air-conditioning technical field, particularly a kind of one drag two air-conditioner outdoor unit.
Background technology
The fixed air-conditioning of double-compressor one drag two frequently be made of two indoor sets and off-premises station that two evaporimeters constitute respectively, but outdoor refrigeration system is to be made of two compressors, two capillaries and a public condenser etc.; Air circulation system is made up of turnover wind apparatus, air ducting, fan and fan electromotor etc.
Each compressor links to each other with the condenser inlet pipe by blast pipe, condenser links to each other with capillary by the condensator outlet pipe, by connect the respectively evaporimeter of two indoor sets of stop valve, each indoor set links to each other with off-premises station by the high-low pressure tube connector respectively afterwards.Condenser is made up of copper pipe and fin, and it can be single, also can be double.
In the air-conditioner of prior art, existing one drag two off-premises station heat exchanger is divided into two parts independent of each other up and down, though both are in full accord for indoor set, but it is outdoor because the difference of dimensional structure (the U type pipe quantity of two systems may be different) or air-out mode, cause this two parts heat exchange situation also different, therefore, its throttling arrangement (capillary) is generally all inequality, and coolant quantity also may be inequality.
As shown in Figure 1, be conventional one drag two outdoor heat exchanger, comprise condenser first inlet tube 1, condenser first outlet 2, condenser first inlet tube 3, condenser second outlet 5, left plate 7, right plate 4, radiating fin 6, U type pipe 8.This condenser is divided into A system and B system, two systems are independent fully, when whole system is moved, because two parts heat exchanger heat exchange effect is inhomogeneous, it is better a part of heat exchanger heat exchange effect to occur, and the phenomenon of other a part of heat exchanger heat exchange weak effect, therefore, system can't bring into play the exchange capability of heat and the effect of whole air-condition heat exchanger, and whole efficiency is lower.
Like this, even if indoor refrigeration system is the same, but because outdoor refrigeration system U type pipe quantity difference, or condenser locations is asymmetric, or the heat exchange inequality that causes of air-out mode difference, just need design and mates each refrigeration system, not only time-consuming, and because monoblock type heat exchanger size is bigger, required input to dash curved equipment such as rise bigger, spillage of material is big.
The utility model content
The technical problems to be solved in the utility model provides a kind of off-premises station that adopts condenser small-sized, the position symmetry, the different Heat Exchanger in Refrigeration System heat exchange effects of this off-premises station are identical, match time and energy are few, and highly versatile can be given full play to the whole exchange capability of heat of heat exchanger.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of air-conditioner outdoor unit, comprise installation chassis, throttle capillary tube, fan system and compressor, installation chassis is separately installed with first condenser and second condenser along the position of diagonal symmetry, first condenser and second condenser be at the edge of installation chassis, and first condenser and second condenser are connected with throttle capillary tube with separately compressor respectively.
Described first condenser comprises first member plate, right end plate, fin and condenser pipe, described first member plate places the fin left side, right end plate places the fin right side, condenser pipe passes fin and is connected between first member plate, the right end plate, and the import of condenser pipe and the outlet of condenser pipe are stretched out from the side plate of condenser; First structure of condenser and second condenser are along the diagonal symmetry.
Described fin is a radiating fin, and the pitch of fins of fin is identical.
Described condenser pipe is a U type pipe.
Described first condenser and the second condenser end plates side are provided with and are used for the hole that is fastenedly connected with installation chassis.
Described fan system is the top air-out mode.
Scheme of the present utility model also can offer the air-conditioning reference of four compressors except being suitable for the double-compressor air-conditioning device.
The utility model with respect to the beneficial effect of prior art is: the condenser size that the condenser size of the utility model off-premises station is more traditional significantly reduces, and inputly dashes curved equipment die size such as rise and greatly reduces, and spillage of material is little; The utility model off-premises station uses two condensers that are symmetric form, condenser is installed in around the air-conditioner outdoor unit chassis, can guarantee that every cover refrigeration system operation conditions is in full accord, air-conditioning refrigeration system is structurally symmetrical fully like this, only need coupling one cover capillary, just can realize coupling, save time and effort a whole set of air-conditioning, simultaneously, improve heat exchange efficiency; If one of them condenser is damaged, the another one condenser can also continue to use, and in this case, only needs to change one of them condenser, reaches the purpose of saving cost.
