The structure of condenser schematic diagram that Fig. 3 relates to for the utility model.
Be labeled as among the figure: condenser 1, blower fan 2, compressor assembly 3, sound panel 4, condenser partition wall 5, wind isolation board 6, cover plate 7, side plate 8, cooling fin 11, condenser pipe 12, internal layer condenser pipe 121, outer condenser pipe 122.
The specific embodiment
As Fig. 1, Fig. 2, shown in Figure 3 be the high off-premises station that is used for central air-conditioning of a kind of heat exchange efficiency that the utility model provides.Described off-premises station comprises the condenser 1 of two cover independent operatings, two groups of blower fans 2 and casings, condenser 1 and blower fan 2 are installed in the casing, one group of blower fan 2 of the installation of every cover condenser 1 outside correspondence, every cover condenser 1 and corresponding blower fan 2 constitute the air discharge structure that a cover independently can be controlled.Like this, by constituting the air discharge structure that a cover independently can be controlled, every cover heat exchange system can independently be controlled, thereby improved the heat exchange efficiency of air-conditioner outdoor unit greatly between every cover condenser 1 of off-premises station and the corresponding blower fan 2, both save the energy, reduced use cost again.
Certainly also comprise the existing compressor assembly 3 of two covers in the above-mentioned embodiment, and two cover compressor assemblies 3 remain the mo(u)ld bottom half structural configuration, so when work, its noise is also bigger, on the distribution of weight of structure, center of gravity is higher, also is not easy to transport.Noise when working in order to reduce off-premises station is beneficial to transportation simultaneously, and the casing of off-premises station is a cover single-piece frame, and the compressor assemblies 3 of two cover independent operatings are installed in the lower right side in the casing.Further for the structure that makes air discharge structure try one's best simple, that manufacturing cost is tried one's best is low, two cover condensers 1 are installed in upper left side and the lower-left side in the casing respectively, are installed in sound panel 4 on vertical between condenser 1 and the compressor assembly 3; Described air discharge structure comprises condenser 1, blower fan 2, condenser partition wall 5, wind isolation board 6, cover plate 7, side plate 8 and sound panel 4; Condenser partition wall 5 is between two cover condensers 1, and wind isolation board 6 is between two adjacent groups blower fan 2, and cover plate 7, sound panel 4 and side plate 8 belong to the part of casing, and sound panel 4 and side plate 8 lay respectively at the right side and the front side of blower fan; 7 fens upper cover plates of cover plate and lower cover lay respectively at the upside and the downside of blower fan 2, so just can in every cover heat exchange system, form one simple in structure, low cost of manufacture, the air discharge structure that can independently control again.
We know, the quality of air-conditioner outdoor unit heat exchange effect, except outside the Pass the air discharge structure with the outside has, the arrangement of the condenser pipe 12 of condenser 1 inside, and it is also most important with the circulation form of refrigerant in condenser pipe 12, in order effectively to improve heat exchange efficiency, described condenser 1 comprises cooling fin 11 and the condenser pipe 12 that is arranged in the cooling fin 11; Condenser pipe 12 makes progress respectively to the lower edge folk prescription in being coiled in cooling fin 11 from the centre of condenser 1, and refrigerant temperature is changed along the pipeline coil direction, avoids the overlapping of condenser pipe 12 high-temperature regions and low-temperature space; Condenser pipe 12 also can avoid refrigerant to be back near the compressor import and export from the centre upwards coiling downwards respectively of condenser 1 simultaneously, reaches the stability of raising system operation, the purpose that prolongs the compressor life-span.
In heat exchanging process, carry out whether existing between the material of heat exchange the size of the temperature difference and the temperature difference, it is the key of decision heat exchanger effectiveness height, in order effectively to improve heat exchanger effectiveness, condenser pipe 12 in condenser 1 comprises that internal layer condenser pipe 121 is communicated with the top and the bottom of outer condenser pipe 122 at condenser 1 near the internal layer condenser pipe 121 of blower fan 2 with away from the outer condenser pipe 122 of blower fan 2; The refrigerant inlet is positioned on the internal layer condenser pipe 121 at middle part, and outlet is positioned on the outer condenser pipe 122 at middle part, and the gateway end of compressor assembly 3 is connected with the refrigerant gateway end of condenser 1 respectively.During refrigeration, refrigerant enters condenser 1 from the inlet at internal layer condenser pipe 121 middle parts, enter the outer condenser pipe 122 of same level circle again in condenser 1 upper and lower through internal layer condenser pipe 121 cooling backs, and then cooling in outer condenser pipe 122, flow out until outlet from the outer condenser pipe 122 at middle part, therefore the refrigerant temperature in the internal layer condenser pipe 121 is higher than the refrigerant temperature in the outer condenser pipe 122 all the time, and internal layer condenser pipe 121 ambient air temperature also are higher than outer condenser pipe 122 ambient air temperature, therefore remain a temperature difference between refrigerant and the air, thereby effectively raise heat exchange efficiency.More than be according to when refrigeration refrigerant the outlet of turnover definition and inlet and refrigerant flow to, refrigerant flows to opposite when heating.
