Abstract
The utility model provides an air conditioner outdoor unit with a defrosting heater. The air conditioner outdoor unit comprises an outdoor unit body, a radiating fan, a heat exchanger and an outer casing, wherein the radiating fan, the heat exchanger and the outer casing are fixed on the outdoor unit body, the defrosting heater is mounted at an air inlet of the outer casing or on the heat exchanger, and the defrosting heater is electrically connected with the outdoor unit body. The defrosting heater adopted on the air conditioner outdoor unit can remove frost on the heat exchanger at lower temperature outdoors, thereby increasing heat exchanging effect of an air conditioner with the external and strengthening heating capacity of a heat pump of the air conditioner. The air conditioner outdoor unit with a defrosting heater can be widely used in cold region in winter.
Description
Technical field
The application relates to the air-conditioner technical field, especially the device of the heating of air-conditioner defrosting.
Background technology
Because winter temperature is lower, is positioned at the northern China place and has heating installation usually.But consider that for convenience increasing family adopts air conditioning and heating.For the heating of air-conditioning, can control at any time, but when outdoor temperature is lower than zero degree, the easy frosting of outdoor heat converter, must defrost this moment with defrosting mode.Particularly when temperature was lower than-5 ℃, even defrosting back heating effect is still very poor, this can assist defrosting and heating efficiency is provided with regard to a kind of mode of eager needs.
Chinese patent (patent No. 99228217.9) discloses a kind of quickly defrosting air-conditioner patent, its composition comprises compressor, reversal valve, condenser, choke valve, evaporimeter, working medium surge drum, connecting line, through reversal valve, surge drum to the air-breathing loop of circulating of the thermal technology between the compressor electric heater unit of being made up of heating, insulation sleeve and cable is being installed from evaporimeter.Electric heater unit is to the heating of the liquid refrigerant in air-breathing loop vaporization, the working medium form that compressor is sucked is saturated dry saturated steam, reach the purpose of quickly defrosting, regulate, just can make heat pump give play to best heating effect by electric heater unit being carried out suitable temperature control.
Above patent uses electrical heating to assist defrosting, and effect is preferably arranged.But because the principle of defrosting is to utilize the working medium after gasifying to defrost, reduced the temperature of working medium, made heating effect be affected.
Summary of the invention
Technical problem to be solved in the utility model is the deficiency that overcomes prior art, provide a kind of simple in structure, can assist defrosting, and then improve the air-conditioner outdoor unit of heating effect.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of air-conditioner outdoor unit that has Defrost heater, contain off-premises station main body, radiator fan, heat exchanger, shell, radiator fan, heat exchanger, shell are fixed on the off-premises station main body, its structural feature is: on the air inlet place of shell or heat exchanger Defrost heater is installed, Defrost heater is electrically connected with the off-premises station main body.
Above-mentioned Defrost heater is any or several composition in heater strip, heating plate, heating tube, the heating plate, and that Defrost heater is is netted, grid-like, any or several shape in the serpentine bend shape.
The outer insulating barrier that is with of above-mentioned Defrost heater.
The beneficial effects of the utility model are:
1, directly adopt heating element heater to heat at off-premises station heat exchanger air intake oral-lateral, the effect that plays defrosting that can maximum efficiency, and improve the heat pump heating effect.
2, the design of this patent need not existing structure is changed especially, and is portable strong, can be widely used on the off-premises station of cold and hot type heat pump air conditioner.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is embodiment 1 structural representation of the present utility model.
Fig. 3 is embodiment 2 structural representations of the present utility model.
Below in conjunction with drawings and Examples the utility model is further specified.
The specific embodiment
A kind of air-conditioner outdoor unit that has Defrost heater, as shown in Figure 1 and Figure 2, contain off-premises station main body, radiator fan, heat exchanger, shell, radiator fan, heat exchanger, shell are fixed on the off-premises station main body, air inlet place at shell is equipped with Defrost heater, and Defrost heater is electrically connected with the off-premises station main body.It is netted that Defrost heater is that heater strip is.The outer insulating barrier that is with of Defrost heater.
A kind of air-conditioner outdoor unit that has Defrost heater, as shown in Figure 3, contain off-premises station main body, radiator fan, heat exchanger, shell, radiator fan, heat exchanger, shell are fixed on the off-premises station main body, Defrost heater is installed on heat exchanger, and Defrost heater is electrically connected with the off-premises station main body.Defrost heater is that heating tube is the serpentine bend shape, the outer insulating barrier that is with of Defrost heater.
Operation principle: when outdoor temperature is low,, all reach subzero, on heat exchanger 3, generate frost at this moment easily, thereby hinder the heat exchange of heat exchanger 3 and air, influence the heating effect of heat pump because refrigerant and outdoor temperature in the heat exchanger 3 are very approaching.Allow Defrost heater 5 energising work by control off-premises station main body 1 this moment, the heat that produces heats Defrost heater 5 ambient airs, and under 2 effects of heat exchange fan, heat exchanging device 3 heats, thereby the frost of knot on the heat exchanger 3 is removed, increase the heat exchange effect of heat exchanger 3, improve the heating capacity of heat pump.
