Further, also be laid with electric heater unit on the chassis of described casing.
Further, described solar energy power accumulating device comprises photovoltaic and batteries, and described photovoltaic connects described batteries by charge controller, and the output of described batteries connects the feeder ear of described electric heater unit.
Further, also comprise system control unit and be arranged on the temperature sensor at the cylinder body place of compressor that described system control unit receives the output signal of described temperature sensor and then controls described electric heater unit and starts or stops.
Further, described electric heater unit is heat tape, and this heat tape is wrapped on the described cylinder body.
Further, described heat tape is wrapped in described cylinder body lower end.
Further, heat tape is laid in the condenser place on the described casing chassis, and is fixed on the chassis by fixture.
Further, described fixture is geometrical clamp.
Alternatively, described electric heater unit is electrical heating cover or electrical heating wire.
Compared with prior art, advantage of the present utility model and good effect are as follows: the utility model is by installing solar energy power accumulating device and electric heater unit additional at air-conditioner outdoor unit, taking full advantage of the solar energy power accumulating device on the one hand is that electric energy is powered to electric heater unit with conversion of solar energy, very big energy savings, heat to compressor casing by electric heater unit on the other hand, guarantee in low-temperature condition lower compression machine lubricating oil proper flow, improve oil return efficient, thereby improve the service life of compressor.
The utility model is simple in structure, does not influence other performances of air-conditioner, owing to directly do simple refit at air-conditioner outdoor unit, thereby processing is simple, cost is lower, has improved the cost performance of air-conditioner.
After reading the specific embodiment of the present utility model by reference to the accompanying drawings, other characteristics of the present utility model and advantage will become clearer.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to do one to the accompanying drawing of required use in embodiment or the description of the Prior Art below introduces simply, apparently, accompanying drawing in describing below is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the control principle block diagram of the utility model embodiment;
Fig. 2 is the structural representation of the utility model embodiment;
Fig. 3 is the vertical view of casing internal structure described in the embodiment;
Fig. 4 is the compressor arrangement schematic diagram;
Among each figure: 1, casing; 1-1, chassis; 2, solar energy power accumulating device; 3, condenser; 4, heat tape; 5, compressor; 6, geometrical clamp.
The specific embodiment
For the purpose, technical scheme and the advantage that make the utility model embodiment clearer, below in conjunction with the accompanying drawing among the utility model embodiment, technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
With reference to figure 2, Fig. 3 and Fig. 4, the present embodiment air-conditioner outdoor unit comprises casing 1, parts such as compressor 5 and condenser 3 are installed in the casing 1, be wound with electric heater unit on the cylinder body of described compressor 5, described casing top is equipped with in order to give the solar energy power accumulating device 2 of described electric heater unit power supply, the present embodiment electric heater unit is heat tape 4, also can adopt electrical heating cover or electrical heating wire etc. certainly.
Present embodiment is not worked or the work initial stage at compressor, give compressor 5 heating by heat tape 4, for saves energy, present embodiment is wrapped in heat tape 4 bottom of compressor 5 cylinder bodies, its reason is: lubricating oil is positioned at the bottom of compressor 5, when outdoor temperature is about 0 ℃, oil body can increase, mobile variation, service efficiency can reduce, heat tape 4 is wrapped in the cylinder body bottom, is exactly to lubricating oil heating, the easier startup of compressor so in fact.But for preventing compressor temperature too high service life that influences compressor, the heating of heat tape on when compressor operating is about five minutes, need disconnecting cylinder body, specifically can control by control module in house software program, when beginning to heat as heat tape on to cylinder body, start timer, and in advance timer is set 5 minutes timing, timing arrives, and control module cuts off the feeder ear of heat tape.
Because casing chassis 1-1 is provided with osculum, in order to prevent when temperature is low, osculum place water freezing stops up osculum, present embodiment also is laid with heat tape 4 on the 1-1 of the chassis of casing, the concrete laying of heat tape 4 is with reference to figure 3, heat tape 4 is laid along condenser, and is fixed on the 1-1 of chassis by geometrical clamp 6, certainly also can be by immobilization with adhesive tape.Like this, the heat tape of laying makes the operating ambient temperature of off-premises station improve, avoid on the one hand osculum easily to freeze under the cold environment in the winter time and the phenomenon of the easy frosting of condenser, guaranteed on the other hand in low-temperature condition lower compression machine lubricating oil proper flow, improved oil return efficient.
Thereby for fear of the service life of the too high influence compression of whole off-premises station operating ambient temperature, can limit by the power supply output to the solar energy power accumulating device on the one hand, with reference to figure 1, the described solar energy power accumulating device of present embodiment comprises photovoltaic and batteries, described photovoltaic connects described batteries by charge controller, the output of described batteries connects the feeder ear of described electric heater unit, selecting suitable output voltage can protect compressor is operated under the suitable temperature, thereby promote heating energy efficiency ratio to greatest extent, the present embodiment output voltage is controlled about 30 ℃ for the temperature that can guarantee heat tape; Also can control to realize by system on the other hand, as at the cylinder body place of compressor mounting temperature sensor, this temperature sensor links to each other with system control unit, and described system control unit receives the output signal of described temperature sensor and then controls described electric heater unit and starts or stops.
It should be noted that at last: above embodiment only in order to the technical solution of the utility model to be described, is not intended to limit; Although with reference to previous embodiment the utility model is had been described in detail, those of ordinary skill in the art is to be understood that: it still can be made amendment to the technical scheme that aforementioned each embodiment puts down in writing, and perhaps part technical characterictic wherein is equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution break away from the spirit and scope of each embodiment technical scheme of the utility model.
