Abstract
The utility model relates to an air conditioning equipment, in particular to an air conditioner with an auxiliary defroster. The utility model comprises a control switch and an electronic heated device, wherein the electronic heated device which is arranged on a heat exchanger outside of the air conditioner is connected with the control switch. The electronic heated device is recumbently arranged along the length direction of a heat exchange tube of the heat exchanger outside or arranged parallel to the heat exchange tube of the heat exchanger outside. The utility model is capable of delaying frost accumulate on the heat exchanger outside and shortening defrost time of the air conditioner.
Description
Technical field
The utility model relates to air-conditioning equipment, particularly relates to a kind of air-conditioner with auxiliary defroster.
Background technology
Present heat pump type air conditioner, under the situation of environment abominable (referring generally to the climate condition of low temperature and high relative humidity), the frequent frost of knot on outdoor heat exchanger that occur removes clean or the long too much phenomenon of indoor temperature decline that makes of defrosting time during heating operation in the winter time.When serious, also can on outdoor heat exchanger and chassis, gather thick ice sheet, stop up outdoor heat exchanger, efficiency of heat exchanger greatly be descended, thereby further influence the heating effect of air-conditioner.In order to address the above problem, the existing measure that improves this respect occurs, as the patent of announcing on May 31st, 2,000 99221688.5 that is called " a kind of heat pump type air conditioner with auxiliary defroster " of company of Haier application; Disclose on a kind of off-premises station chassis at air-conditioner and adorned a heating wire or electrothermal tube, this heating wire or electrothermal tube were fixed on the chassis with the colloid fixture around one week of heat exchanger of air-conditioner.This has solved the situation that thick ice sheet gathers to a certain extent on the chassis, but does not have effect to delaying the defrosting time that gathers and shorten air-conditioner of frost on outdoor heat exchanger.
The utility model content
Technical scheme provided by the utility model is exactly in order to address the above problem, to delay the defrosting time that gather and shorten air-conditioner of frost on outdoor heat exchanger.
Technical scheme provided by the utility model is exactly: a kind of air-conditioner with auxiliary defroster, comprise control device, electric heater unit, and electric heater unit is connected with gauge tap, and electric heater unit is laid on the outdoor heat exchanger of described air-conditioner.
Especially, described electric heater unit is parallel to the heat exchanger tube layout on the described outdoor heat exchanger.
Especially, described electric heater unit is along the layout that reclines of the heat exchanger tube length direction on the described outdoor heat exchanger.
Utilize the utility model to be equivalent on the off-premises station heat exchanger of air-conditioner, install a heat source generator, this heat source generator under the control of control device, by heat conducting mode with the heat diffusion that produces other parts to the outdoor heat exchanger.Under defrosting operating condition, can quickly defrosting, shorten defrosting time; Under heating condition, can effectively prevent frosting, to improve frost gathering on outdoor heat exchanger.Thereby reach the purpose of improving the air-conditioning heating effect.
Description of drawings
Fig. 1 is that the electric heater unit on the utility model embodiment 1 outdoor heat exchanger is arranged schematic diagram;
Fig. 2 is that the A of Fig. 1 is to view;
Fig. 3 is that the electric heater unit on the utility model embodiment 2 outdoor heat exchangers is arranged schematic diagram.
The specific embodiment
First embodiment
As illustrated in fig. 1 and 2, an air-conditioner outdoor unit comprises outdoor heat exchanger 1, auxiliary defroster, central controller, and described auxiliary defroster comprises gauge tap, electric heater unit 4.Outdoor heat exchanger 1 is made up of complex root heat exchanger tube 2 and multi-disc heat exchange fin 3 and the side plate that conveniently installs and fixes, and described heat exchanger tube 2 passes the hole that is preset on the heat exchange fin 3 according to certain mode; Described electric heater unit 4 is arranged in heat exchanger tube 2 modes that are parallel on the described outdoor heat exchanger 1, is installed in other headspaces that are parallel to heat exchanger tube 2 on the outdoor heat exchanger 1.Described electric heater unit 4 is connected on the described gauge tap, is connected on the described central controller by gauge tap.When air conditioner enters the Defrost operation pattern, central controller sends heating signal to auxiliary defroster, electric heater unit 4 begins to heat up to the end of Defrost operation pattern or of short duration time-delay is arranged, heat that electric heater unit 4 produces and air-conditioner inverted running at the heat that is produced on the outdoor heat exchanger by heat conducting mode with heat diffusion other parts to the outdoor heat exchanger, all remove with the frost of the formation on the assurance outdoor heat converter.
Second embodiment
As shown in Figure 3, described electric heater unit 4 is along the layout that reclines of heat exchanger tube 2 length directions on the described outdoor heat exchanger 1; Described heat exchanger tube 2 passes the hole that is preset on the heat exchange fin 3 according to certain mode.
In addition, the outdoor temperature induction installation also is housed on off-premises station, when the outdoor temperature induction installation is experienced outdoor temperature and is lower than a certain setting value, central controller also can send heating signal to auxiliary defroster, thereby compensation is because outdoor temperature is crossed the problem of the air conditioner heat-production poor effect that low outdoor heat exchanger decrease in efficiency causes.Simultaneously,, can delay the formation of frost on the outdoor heat exchanger under the low temperature situation, prevent that air-conditioner from owing to the frequent defrosting phenomenon that frosting causes, helping improving the heating effect of air-conditioner because the electric heater unit additional heat is arranged.
Heating wire or electric heating tube that described electric heater unit 4 encapsulates for the resistant to elevated temperatures silicon rubber that adopts high-insulation, its leakage rate only is 0.01mA at 2000V voltage (placing in the water), can also adopt change power constant temperature electric heating silk, the electric heating tube of other types.
The utility model is simple in structure, and hardly with the structure of changing existing air-conditioner, but effect is remarkable, is the feasible measure that improves air-conditioner defrosting and heating effect.Through the contrast experiment, utilize the utility model (defrosting 2 to 3 minutes) and can not shorten more than 6 minutes than utilizing the utility model (defrosting 8 to 10 minutes) defrosting time.Under the identical condition of heating effect, utilize the utility model (defrost interval 75 to 90 minutes) than not utilizing the utility model (defrost interval 45 to 60 minutes) defrost interval time can prolong more than 30 minutes.
