The outdoor unit of the central air conditioner comprises a condenser set arranged between a machine roof 3 and a partition plate 4 and a blower 2 arranged on the machine roof 3, wherein the condenser set is formed by a plurality of condensers 1 which are arranged at the periphery of the blower 2 and perpendicular to the machine roof 3; and the partition plate 4, the machine roof 3 and the peripheral condensers 1 enclose to form a closed space. Compared with the prior outdoor unit of V-shaped condensers, the outdoor unit is small in overall size and energy-saving, and is applicable to the construction of the central air conditioning system.
Description
Technical field
The utility model relates to a kind of heat transmission equipment, especially a kind of off-premises station of central air-conditioning.
Background technology
At present, the central air-conditioning off-premises station adopts two independently condenser composition " V " type structures usually, two respectively corresponding compressors of condenser, thereby constitute the multisystem off-premises station, and employing top air-out mode, promptly " V " type opening is upwards arranged, blower fan is installed in off-premises station machine top, but " V " type structural base causes whole bottom heat exchange efficiency low owing under the free air space, cause air quantity less than normal, exchange capability of heat does not make full use of, Energy Efficiency Ratio is lower during the air-conditioner operation, and power consumption is big, causes the waste of the energy.
The utility model content
For the deficiency of the off-premises station that overcomes existing central air-conditioning, technical problem to be solved in the utility model provides the off-premises station of a kind of heat exchange efficiency height, energy-conservation central air-conditioning.
The technical scheme that its technical problem that solves the utility model adopts is: the off-premises station of central air-conditioning, comprise the blower fan that is arranged on condenser group between machine top and the dividing plate, is arranged on the machine top, described condenser group is by being arranged in around the blower fan and forming with the perpendicular a plurality of condensers in machine top, by dividing plate, machine top and around condenser surround the formation confined space.
The beneficial effects of the utility model are: by improving the circulation of air between condenser and the blower fan, the especially circulation of air of condenser bottom has improved the heat exchange efficiency of bottom, and the heat exchange efficiency height has been saved the energy.
After the condenser heat exchange efficiency improves, in order fully to be beneficial to the exchange capability of heat of condenser, described a plurality of condensers are divided into many groups, and every group condenser is by outlet distributor and inlet dispenser parallel connection, thereby increased the condensation efficiency of condenser, by with the coupling of high-efficient compressor and air-foil fan, can reduce number of compressors, thus when guaranteeing equal refrigerating capacity, can reduce the volume of off-premises station, save installing space, and further reduce power consumption, reach purpose of energy saving.

The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
As shown in Figure 1, the off-premises station of central air-conditioning of the present utility model, comprise the blower fan 2 that is arranged on condenser group between machine top 3 and the dividing plate 4, is arranged on machine top 3, described condenser group is by being arranged in around the blower fan 2 and pushing up 3 perpendicular a plurality of condensers 1 with machine and forms, by dividing plate 4, machine top 3 and around condenser 1 surround the formation confined space.Described a plurality of condenser 1 is divided into many groups, and every group condenser 1 is by outlet distributor 12 and inlet dispenser 11 parallel connections.
Concrete, as Fig. 2, Fig. 4, Fig. 5, shown in Figure 6, described condenser group is to comprise the rectangular configuration of four " L " type condensers 1 and be divided into two groups, two condensers 1 of every group are by outlet distributor 12 and inlet dispenser 11 parallel connections, because described each condenser 1 comprises a plurality of condensation branch roads 13, so the outlet 132 of each condensation branch road 13 is passed through outlet distributor 12 and inlet dispenser 11 parallel connections respectively with inlet 131.
Scheme of the present utility model is by improving the circulation of air between condenser 1 and the blower fan 2, and the especially circulation of air of condenser 1 bottom has improved the heat exchange efficiency of bottom, and the heat exchange efficiency height has been saved the energy.And after the raising of condenser 1 heat exchange efficiency, in order fully to be beneficial to the exchange capability of heat of condenser 1, increased the condensation efficiency of 1 pair of refrigerant of condenser by the mode of parallel connection, and the multiple branch circuit structure has also further increased the efficient of condensation, by with the coupling of high-efficient compressor and air-foil fan, can reduce number of compressors, thereby when guaranteeing equal refrigerating capacity, can reduce the volume of off-premises station, save installing space, and further reduce power consumption, reach purpose of energy saving.
The shape that condenser was surrounded as also can adopt polygon, circle etc. except adopting rectangle, and the shape of condenser, what and grouping should be selected and mate according to concrete demand.
In order further to improve heat exchange efficiency, the pipeline of described each condensation branch road 13 is coiled into internal layer and the skin that two rows lay respectively at condenser, and the inlet 131 of condensation branch road 13 is communicated with internal layer pipeline 142.During refrigeration, refrigerant 131 enters from entering the mouth, through entering the outer pipeline 141 of same circle after 142 coolings of internal layer pipeline again, and then enter the internal layer pipeline 142 of next circle, circulate successively until flowing out from exporting 132, therefore the refrigerant temperature in the internal layer pipeline 142 is higher than the refrigerant temperature in the outer pipeline 141 of same circle all the time, and internal layer pipeline 142 ambient air temperature also are higher than outer pipeline 141 ambient air temperature, therefore remain a temperature difference between refrigerant and the air, thereby further improved heat exchange efficiency.
It is the turnover definition of refrigerant during according to refrigeration that outlet described here and inlet and refrigerant flow to.Refrigerant flows to opposite when heating.
