The air conditioner indoor unit can adjust the position states of the electric heater, and is beneficial for reducing the affects of an auxiliary electric heater to system air quantity and system performance.
Description
Technical field
The utility model relates to air-conditioning technical field, particularly a kind of air conditioner room unit with the auxiliary heating function of electricity.
Background technology
Have the constant speed domestic air conditioner now, have the problem of winter refrigeration poor effect more.This is because mostly heat pump type air conditioner is that according to the cooling condition designed system heating performance of air-conditioning descends along with the decline (rising of humidity) of outdoor temperature obviously; And owing to outdoor temperature, will cause evaporimeter frosting during winter heating; Usually, air-conditioner needed to stop heating and defrosting after operation a period of time, caused heating effect relatively poor thus.
In the prior art, convertible frequency air-conditioner is by improving compressor frequency, and the constant speed air-conditioning modes that adopt indoor increase electrical auxiliary heater (being generally PTC, semistor) to remedy the problem of heating capacity deficiency more.Air conditioner room unit as shown in Figure 1, electric heater 1 are fixedly mounted in the air channel 4 between indoor heat exchanger 2 and the tubular wine wheel 3.Unadjustable because of the location status of electric heater 1, the air quantity of system is had considerable influence: be placed on the big place of air quantity, influential to the performance of system, particularly the refrigeration situation that need not use is more outstanding; Be placed on the less place of air quantity, then the heat of heater 1 generation is difficult for taking away, and causes temperature rising in the air channel easily, increases condensation load, influences heating capacity.
The utility model content
The utility model purpose is, a kind of air conditioner room unit is provided, and can reduce the influence of electrical auxiliary heater to systematic air flow and systematic function.Make in the situation that does not influence systematic air flow and ability as far as possible, especially when not using the refrigeration situation of electric heater, increase the heating capacity of system, improve users'comfort.
At above-mentioned technical problem, the air conditioner room unit that the utility model provides comprises electric heater, is installed in the air channel between indoor heat exchanger and the tubular wine wheel; Also comprise motor, be fixed on the side end panel, and be connected with the automatically controlled plate of air conditioner room unit; One end of described electric heater connects described motor, and the other end connects side end panel.
Described electric heater vertically parallel with the central axis of described tubular wine wheel.
Described indoor heat exchanger is a multi-fold structure.
Described electric heater is installed in the position of air quantity maximum in the described air channel.
Described electric heater comprises the many resistors that are arranged in parallel.
Described resistor is two.
Described resistor is cylindrical.
Described resistor is provided with fin.
Described resistor is a semistor.
Compared with prior art, electrical heating electric heater in the indoor set air-conditioner of the present utility model connects motor, thereby can sway, can adjust the location status of electric heater thus, this helps reducing the influence of electric heater to systematic air flow and systematic function.Especially, heater is installed in the position of air quantity maximum in the air channel: when heating, the one side that electric heater is wide is facingd the wind, and can take away the heat of electric heater as far as possible, can not cause the temperature in the air channel to rise, and does not influence the performance of system; When refrigeration, electric heater is turned to narrower one side facing the wind, reduce front face area, reduce influence to systematic air flow.

The specific embodiment
Basic design of the present utility model is that electric heater connects motor, and it can be swayed, thereby adjusts the location status of electric heater.
Describe below in conjunction with accompanying drawing and embodiment.
Referring to Fig. 2, Fig. 3, among the embodiment of the utility model air conditioner room unit, resistance-type electrical auxiliary heater 1, be installed in the air channel 4 between indoor heat exchanger 2 and the tubular wine wheel 3, vertically parallel with tubular wine wheel 3 central axis, one end of this electric heater 1 is fastened on the motor 6 on the side end panel 5, and the other end is connected on the side end panel 7, and motor 6 connects automatically controlled plate (scheming not shown).
As shown in Figure 2, because indoor heat exchanger 2 mostly is multi-fold structure, under the effect of tubular wine wheel 3, the wind speed profile in the air channel 4 between indoor heat exchanger 2 and the tubular wine wheel 3 is also inhomogeneous, therefore electric heater 1 is placed in the position of air quantity maximum in the air channel 4.
Referring to Fig. 4, Fig. 5, two cylindrical resistance 11 of electric heater 1 preferred employing in the present embodiment are arranged in parallel, it is provided with the fin 12 of augmentation of heat transfer, can quicken the heat transfer between electric heater 1 and the air thus, prevents that the surface temperature of electric heater 1 is too high.And the cylindrical structural of resistance 11 facings the wind, and can reduce windage, reduces the influence to systematic air flow.
Referring to Fig. 6, when stopping in system, electric heater 1 narrow one side is facingd the wind, and puts according to air quantity maximum wind direction.When refrigeration, indoor heat exchanger 2 evaporates through the cold-producing medium of the gas-liquid two-phase behind the capillary-compensated absorbs heat in evaporimeter after as evaporator operation.Because systematic air flow is bigger than condenser for the influence of evaporimeter, the front face area of electric heater 1 is reduced, to the influence of systematic air flow less than original structure, for the influence of systematic function also less than original structure.Therefore, the position of electric heater 1 is motionless when refrigeration.
Referring to Fig. 7, system is when heating operation, the position of electric heater 1 then changes to some extent, it is signal that its position changes with the indoor environment temperature temperature that temperature sensor was detected: when heating, indoor heat exchanger 2 is as condenser working, gaseous refrigerant heat release condensation in condenser of the HTHP that compressor is got rid of.Because the caloric value of electric heater 1 is bigger, the rising of temperature is the influence of the rising of condensation temperature for condenser in the air channel, change bigger than systematic air flow to condenser, so for condenser, it is bigger that the influence that air quantity that electric heater 1 brings down with the wind changes can not in time blow away the influence that brings than the heat of electric heater 1, and this makes electric heater 1 in the present embodiment can improve the efficient of system effectively.
The position adjustment of electric heater 1 is: when indoor environment temperature during less than 20 ℃, the decrease in efficiency of system, electric heater 1 is under the effect of motor 6, and dextrorotation turn 90 degrees, electric heater 1 unlatching work; System quit work or the indoor environment temperature temperature greater than after 20 ℃, electric heater 1 quits work, and is rotated counterclockwise 90 degree, returns back to the home position.
Only be preferred implementation of the present utility model below, should be pointed out that above-mentioned preferred implementation should not be considered as restriction of the present utility model, protection domain of the present utility model should be as the criterion with claim institute restricted portion.For those skilled in the art, in not breaking away from spirit and scope of the present utility model, can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
