Description
Technical field
The utility model relates to air-conditioner technical field, particularly a kind of variable-frequency multi-connection type air-conditioner.
Background technology
See accompanying drawing 2, the variable-frequency multi-connection type air-conditioner that the multiple room of existing household and working environment use, comprise off-premises station and at least two indoor sets, off-premises station comprises frequency-changeable compressor 8, outdoor heat exchanger 2, outdoor fan 3, liquid pipe 4, tracheae 5 and oil equalizing pipe 9; Indoor set comprises indoor heat exchanger 6 and indoor fan 7.Its frequency-changeable compressor 8 is all with lubricating oil, and lubricating oil enters into heat exchanger with kind of refrigeration cycle, and the oil film formed at heating surface becomes thermal resistance, greatly affects the heat exchange efficiency of heat exchanger.When block combiner uses, need to arrange equal 9 and oily equilibrium code, make construction and installation loaded down with trivial details, refrigeration system and control program complexity, not only increase the cost of whole system, and increase maintenance cost, control the improper compressor that easily causes to burn, whole multiplex system cannot normally be worked.And fluctuations in indoor temperature scope is large, difficulty reaches more comfortable, more energy-conservation environment.
Utility model content
The utility model is in order to solve the problems of the technologies described above, a kind of variable-frequency multi-connection type air-conditioner is provided, adopts without oily frequency-changeable compressor, in kind of refrigeration cycle, there is no lubricating oil, thus the heat exchange efficiency of heat exchanger can be improved, and oil equalizing pipe when can cancel block combiner, simplify installation operation, also can cancel oil balance and control, simplify refrigeration system and control program, easy to maintenance, and it is less to realize fluctuations in indoor temperature scope, reaches more comfortable, more energy-conservation.
To achieve these goals, the utility model provides following technical scheme:
A kind of variable-frequency multi-connection type air-conditioner, it is characterized in that, comprise off-premises station and at least two indoor sets, described off-premises station comprises frequency-changeable compressor, outdoor heat exchanger and outdoor fan, described frequency-changeable compressor is magnetic suspension or air-suspending DC frequency-changing vortex or rotor compressor, described indoor set comprises indoor heat exchanger and indoor fan, and described at least two indoor sets are connected in parallel on described off-premises station.
Further, described off-premises station is multiple stage, and multiple stage off-premises station is combined into modular refrigeration system, and described multiple stage off-premises station is connected in series.
Further, described outdoor fan and described indoor fan are direct current or AC blower fan.
Further, described outdoor heat exchanger and described indoor heat exchanger are copper aluminum finned tube heat exchanger or full aluminium micro-channel heat exchanger.
The beneficial effects of the utility model are:
Overcome existing variable-frequency multi-connection type air-conditioner band oil run make that the heat exchange efficiency of heat exchanger declines, the defect of refrigeration system and control program complexity, adopt without oily frequency-changeable compressor, lubricating oil is not had in kind of refrigeration cycle, thus the heat exchange efficiency more than 15% of heat exchanger can be improved, and oil equalizing pipe when can cancel block combiner, simplify installation operation, also can cancel oil balance to control, simplify refrigeration system and control program, easy to maintenance, and fluctuations in indoor temperature scope control can be realized at ± 0.05 DEG C, reach more comfortable, more energy-conservation.
Accompanying drawing explanation
Fig. 1 is the utility model system schematic;
Fig. 2 is existing variable-frequency multi-connection type air-conditioner system schematic diagram.
In figure: 1 be frequency-changeable compressor, 2 be outdoor heat exchanger, 3 be outdoor fan, 4 be liquid pipe, 5 be tracheae, 6 be indoor heat exchanger, 7 be indoor fan, 8 be frequency-changeable compressor, 9 for oil equalizing pipe.
Detailed description of the invention
Elaborate below in conjunction with the detailed description of the invention of accompanying drawing to the utility model variable-frequency multi-connection type air-conditioner.
See accompanying drawing 1, variable-frequency multi-connection type air-conditioner comprises off-premises station and at least two indoor sets, and off-premises station comprises frequency-changeable compressor 1, outdoor heat exchanger 2, outdoor fan 3, liquid pipe 4 and tracheae 5; Frequency-changeable compressor is magnetic suspension or air-suspending DC frequency-changing vortex or rotor compressor, is oil-free compressor.When multiple stage off-premises station is connected in series, be combined into modular refrigeration system.The quantity of indoor set at least two, is connected in parallel use according to environment for use, is generally 3 to 10.Indoor set comprises indoor heat exchanger 6 and indoor fan 7.
Outdoor fan and described indoor fan are direct current or AC blower fan, and outdoor heat exchanger and described indoor heat exchanger are copper aluminum finned tube heat exchanger or full aluminium micro-channel heat exchanger.
Operation principle of the present utility model is as follows:
See accompanying drawing 1, owing to adopting oil free type frequency-changeable compressor 1, in kind of refrigeration cycle, there is no lubricating oil, lubricating oil is not had to enter into outdoor heat exchanger 2 and indoor heat exchanger 6, do not form the heat exchange of oil film effect heat exchanger, thus can improve the heat exchange efficiency of heat exchanger, the efficiency of whole system gets a promotion.Therefore can cancel the oil equalizing pipe 9 during block combiner, simplify installation operation, also can cancel oil balance and control, simplify refrigeration system and control program.The cost of whole system can not only be reduced, and can maintenance cost be reduced.And refrigeration is faster, can realize fluctuations in indoor temperature scope control at ± 0.05 DEG C, reach more comfortable, more energy-conservation.
See accompanying drawing 2, adopt frequency-changeable compressor 8, with lubricating oil in kind of refrigeration cycle, lubricating oil enters into outdoor heat exchanger 2 and indoor heat exchanger 6, forms the heat exchange of oil film effect heat exchanger, thus reduces the heat exchange efficiency of heat exchanger, the efficiency of whole system is reduced.And during block combiner, need oil equalizing pipe 9 and the control of oil balance, make construction and installation loaded down with trivial details, refrigeration system and control program complexity, not only increase the cost of whole system, and increase maintenance cost.
The implementation of this utility model can have following improvement mode:
Indoor set can increase configuration humidifying component, the new blower fan of permanent oxygen or oxygen permeable membrane aeration system, realizes the permanent net work energy of the permanent oxygen of constant temperature and humidity.
Indoor heat exchanger can increase dehydrating unit, and dehydrating unit comprises dehumidifying flow controller and dehumidifying magnetic valve, and dehydrating unit is connected with indoor heat exchanger.
The utility model can be used for frequency conversion one-driving-one air conditioner, adopts without oily frequency-changeable compressor, the effect that same realization is more comfortable, more energy-conservation.
The above is only preferred embodiment of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
